2.8 Common Procedures in Alarm Troubleshooting
Alarm Troubleshooting
This chapter gives a description, severity, and troubleshooting procedure for commonly encountered Cisco ONS 15327 alarms and conditions. Table 2-1 through Table 2-4 give lists of ONS 15327 alarms organized by severity. Table 2-5 gives a list of alarm organized alphabetically. Table 2-6 gives a list of alarms organized by alarm type. For a comprehensive list of all conditions, refer to the Cisco ONS 15454 and Cisco ONS 15327 TL1 Command Guide.
The troubleshooting procedure for an alarm applies to both the Cisco Transport Controller (CTC) and TL1 version of that alarm. If the troubleshooting procedure does not clear the alarm, log onto http://www.cisco.com/tac for more information or call the Cisco Technical Assistance Center (TAC) to report a service-affecting problem (1-800-553-2447).
For alarm profile information, refer to the Cisco ONS 15327 Procedure Guide.
2.1 Alarm Index by Default Severity
The alarm index by severity tables group alarms and conditions by the severity displayed in the CTC Alarms window in the severity (SEV) column. The default standby severity for all ONS 15327 alarms on unprovisioned card ports is Minor, Non-Service Affecting, as defined in Telcordia GR-474. All severities listed in the alarm entry are the default for the active card, if applicable. Alarm severities can be altered from default settings for individual alarms or groups of alarms on a card, node, or network basis.
Note 
The CTC default alarm profile contains alarms that apply to multiple product platforms. The alarms that apply to this product are listed in the following tables and sections.
2.1.1 Critical Alarms (CR)
Table 2-1 lists Critical alarms.
2.1.2 Major Alarms (MJ)
Table 2-2 lists Major alarms.
2.1.3 Minor Alarms (MN)
Table 2-3 lists Minor alarms.
2.1.4 Conditions (NA or NR)
Table 2-4 lists Not Alarmed or Not Reported conditions.
2.2 Alarms and Conditions Indexed By Alphabetical Entry

2.4 Trouble Notifications
The ONS 15327 uses standard Telcordia categories to characterize levels of trouble. The ONS 15327 reports alarmed trouble notifications in the CTC Alarms window and Not Alarmed (NA) trouble notifications in the Conditions window. Alarms signify a problem that the user needs to fix, such as an LOS (OC-N) alarm (see page 2-83). Conditions notify the user of an event which does not require action, such as a SWTOSEC condition (see page 2-115) or a MANRESET condition (see page 2-88).
Telcordia further divides alarms into Service-Affecting (SA) and NSA status. An SA failure affects a provided service or the network's ability to provide service. For example, a TRMT-MISS alarm (see page 2-121) is characterized as an SA failure. TRMT-MISS occurs when the cable connector leading to a DS-1 port on an XTC card is removed. This affects a provided service because traffic switches to the protect card. The HITEMP alarm (see page 2-71) means that the alarm object is hotter than 122 degrees Fahrenheit (50 degrees Celsius). HITEMP is an NSA failure for a single piece of equipment, or an SA failure for the NE. For example, if the HITEMP alarm is raised against a port with an EQPT object, the alarm is NSA because port and card traffic is protected. If the HITEMP alarm is raised against the NE (shelf), however, it is an SA alarm because a high temperature affects the network's ability to provide service.
2.4.1 Conditions
When an SA failure is detected, the ONS 15327 also sends an AIS condition (see page 2-16) downstream. When the node receives the AIS, the node sends an RFI-L condition (see page 2-101) upstream. AIS and RFI belong in the conditions category and show in the Conditions window of CTC. However, unlike most conditions which are Not Alarmed (NA), Telcordia classifies these conditions as Not Reported (NR).
Both CTC and TL1 report NRs and NAs as conditions when conditions are retrieved. NAs are also reported as autonomous events in TL1 and in the History window of CTC. For a comprehensive list of all conditions, refer to the Cisco ONS 15454 and Cisco ONS 15327 TL1 Command Guide.
2.4.2 Severities
The ONS 15327 uses Telcordia standard severities: Critical (CR), Major (MJ), and Minor (MN). Critical indicates a severe, service-affecting alarm that needs immediate correction. Major is a serious alarm, but the failure has less of an impact on the network. For example, with an LOS (DS-1), a Major alarm, 24 DS-0 circuits lose protection. But with a LOS (OC-N) for an OC-48 card, a Critical alarm, approximately 25,000 DS-0 circuits lose protection.
Minor alarms, such as the FSTSYNC alarm (see page 2-71), do not have a serious affect on service. FSTSYNC lets you know that the ONS 15327 is choosing a new timing reference because the old reference failed. The loss of the prior timing source is something a user needs to look at, but it should not immediately disrupt service.
Telcordia standard severities are the default settings for the ONS 15327. A user may customize ONS 15327 alarm severities with the alarm profiles feature. For alarm profile procedures, refer to the Cisco ONS 15327 Procedure Guide.
This chapter lists the default alarm severity for the active reporting card, if applicable. The default severity for alarms reported by standby cards is always Minor, Non-Service-Affecting.
2.5 Safety Summary
This section covers safety considerations designed to ensure safe operation of the ONS 15327. Personnel should not perform any procedures in this chapter unless they understand all safety precautions, practices, and warnings for the system equipment. Some troubleshooting procedures require installation or removal of cards, in these instances users should pay close attention to the following caution and warnings:
Caution Hazardous voltage or energy might be present when the system is operating. Use caution when removing or installing cards.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Warning Class 1 laser product.
Warning Class 1M laser radiation when open. Do not view directly with optical instruments.
2.6 Alarm Procedures
This section list alarms alphabetically and includes some conditions commonly encountered when troubleshooting alarms. The severity, description, and troubleshooting procedure accompany each alarm and condition.
Note When you check the status of alarms for cards, ensure that the alarm filter icon in the lower-right corner is not indented. If it is, click it to turn it off. When you are done checking for alarms, click the alarm filter icon again to turn filtering back on.
Note When checking alarms, make sure that alarm suppression is not enabled on the card or port. For more information about alarm suppression, see the Cisco ONS 15327 Procedure Guide.
2.6.1 AIS
•Not Reported (NR), Non-Service Affecting (NSA)
The Alarm Indication Signal (AIS) condition in the SONET overhead is secondary to another alarm occurring simultaneously in an upstream node. An incomplete circuit path causes an AIS, for example, when the port on the reporting node is in service (IS) but the DS-3 or OC-N port on a node upstream on the circuit is not in service. The upstream node often reports a loss of service or has an out-of-service (OOS) port. The AIS clears when you clear the primary alarm on the upstream node. However, the primary alarm node might not report any alarms that indicate it is at fault.
Procedure: Clear the AIS Condition
Step 1 Verify whether there are alarms on the upstream nodes and equipment, especially an LOS (OC-N) alarm (see page 2-83) or OOS ports.
Step 2 Clear the upstream alarms using the applicable procedure(s) in this chapter.
Step 3 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.2 AIS-L
•Not Reported (NR), Non-Service Affecting (NSA)
The AIS Line (AIS-L) condition means there is an error in the SONET overhead at the line layer. The AIS-L condition is secondary to another alarm occurring simultaneously in an upstream node. An incomplete circuit path causes an AIS-L, for example, when the port on the reporting node is in service (IS) but a node upstream on the circuit does not have its OC-N port in service. The upstream node often reports an LOS (OC-N) alarm (see page 2-83) or has an OOS port. The AIS-L clears when you clear the primary alarm on the upstream node. However, the primary alarm node might not report any alarms that indicate it is at fault.
Procedure: Clear the AIS-L Condition
Step 1 Complete the "Clear the AIS Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.3 AIS-P
•Not Reported (NR), Non-Service Affecting (NSA)
The AIS Path (AIS-P) condition means there is an error in the SONET overhead at the path layer. The AIS-P condition is secondary to another alarm occurring simultaneously in an upstream node. The AIS-P is caused by an incomplete circuit path, for example, when the port on the reporting node is in service (IS), but a node upstream on the circuit does not have its port in service. The upstream node often reports an LOS (OC-N) alarm (see page 2-83) or has an OC-N port OOS. The AIS-P clears when the primary alarm on the upstream node is cleared. However, the node with the primary alarm might not report any alarms to indicate it is at fault. AIS-P occurs at each node on the incoming OC-N path.
Procedure: Clear the AIS-P Condition
Step 1 Complete the "Clear the AIS Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.4 AIS-V
•Not Reported (NR), Non-Service Affecting (NSA)
The AIS Virtual Tributary (VT) condition means there is an error in the SONET overhead at the VT layer. The AIS-V condition is secondary to another alarm occurring simultaneously in an upstream node. An incomplete circuit path causes an AIS-V, for example, when the port on the reporting node is in service (IS) but a node upstream on the circuit does not have its OC-N port in service. The upstream node often reports an LOS (OC-N) alarm (see page 2-83) or has an OOS port. The AIS-V clears when the primary alarm is cleared. The node with the OOS port might not report any alarms to indicate it is at fault.
An AIS-V error message on the electrical card is accompanied by an AIS-P condition (see page 2-16) on the cross connected OC-N card.
Note If the AIS-V occurred on an XTC-28-3 unused circuit, complete the "Clear AIS-V on XTC-28-3 Unused VT Circuits" procedure on page 1-67.
Procedure: Clear the AIS-V Condition
Step 1 Complete the "Clear the AIS Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.5 APSB
•Minor (MN), Non-Service Affecting (NSA)
The Automatic Protection Switching (APS) Channel Byte Failure (APSB) alarm occurs when line terminating equipment detects protection switching byte failure in the incoming APS signal. The failure occurs when an inconsistent APS byte or invalid code is detected. Some older, non-Cisco, SONET nodes send invalid APS codes if they are configured in a 1+1 protection scheme with newer SONET nodes, such as the ONS 15327. These invalid codes causes an APSB on an ONS node.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the APSB Alarm
Step 1 Use an optical test set to examine the incoming SONET overhead to confirm inconsistent or invalid K bytes.
For specific procedures to use the test set equipment, consult the manufacturer. If corrupted K bytes are confirmed and the upstream equipment is functioning properly, the upstream equipment might not interoperate effectively with the ONS 15327.
Step 2 If the alarm does not clear and the overhead shows inconsistent or invalid K bytes, you might need to replace the upstream cards for protection switching to operate properly.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.6 APSCDFLTK
•Minor (MN), Non-Service Affecting (NSA)
The APS Default K Byte Received (APSCDFLTK) alarm occurs when a bidirectional line switched ring (BLSR) is not properly configured, for example, when a four-node BLSR has one node configured as a unidirectional path switched ring (UPSR). A node in a UPSR or 1+1 configuration does not send the two valid K1/K2 APS bytes anticipated by a system configured for BLSR. One of the bytes sent is considered invalid by the BLSR configuration. The K1/K2 byte is monitored by receiving equipment for link-recovery information.
Troubleshooting for APSCDFLTK is often similar to troubleshooting for a BLSROSYNC alarm (see page 2-30).
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the APSCDFLTK Alarm
Step 1 Complete the "Identify a Ring ID or Node ID Number" procedure to verify that each node has a unique node ID number.
Step 2 Repeat Step 1 for all nodes in the ring.
Step 3 If two nodes have the same node ID number, complete the "Change a Node ID Number" procedure to change one node's ID number so that each node ID is unique.
Step 4 If the alarm does not clear, verify correct configuration of east port and west port optical fibers. (See the "E-W-MISMATCH" section.) West port fibers must connect to east port fibers, and vice versa. The Cisco ONS 15327 Procedure Guide provides a procedure for fibering BLSRs.
Step 5 If the alarm does not clear and if the network is a BLSR, make sure that each protect fiber is connected to another protect fiber and each working fiber is connected to another working fiber. The software does not report any alarm if a working fiber is incorrectly attached to a protection fiber.
Step 6 If the alarm does not clear, complete the "Verify Node Visibility for Other Nodes" procedure.
Step 7 If nodes are not visible, complete the "Verify or Create Node DCC Terminations" procedure to ensure that SONET DCC terminations exist on each node.
Step 8 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.7 APSC-IMP
•Minor (MN), Non-Service Affecting (NSA)
An Improper SONET APS Code (APSC-IMP) alarm indicates invalid K bytes. The APSC-IMP alarm occurs on OC-N cards in a BLSR configuration. The receiving equipment monitors K bytes or K1 and K2 APS bytes for an indication to switch from the working card to the protect card or vice versa. K1/K2 bytes also contain bits that tell the receiving equipment whether the K byte is valid. APSCIMP occurs when these bits indicate a bad or invalid K byte. The alarm clears when the node receives valid K bytes.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the APSC-IMP Alarm
Step 1 Use an optical test set to determine the validity of the K byte signal by examining the received signal.
For specific procedures to use the test set equipment, consult the manufacturer.
If the K byte is invalid, the problem is with upstream equipment and not in the reporting ONS 15327. Troubleshoot the upstream equipment using the procedures in this chapter, as applicable. If the upstream nodes are not ONS 15327s, consult the appropriate user documentation.
Step 2 If the K byte is valid, verify that each node has a ring ID that matches the other node ring IDs. Complete the "Identify a Ring ID or Node ID Number" procedure.
Step 3 Repeat Step 2 for all nodes in the ring.
Step 4 If a node has a ring ID number that does not match the other nodes, make the ring ID number of that node identical to the other nodes. Complete the "Change a Ring ID Number" procedure.
Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.8 APSCINCON
•Minor (MN), Non-Service Affecting (NSA)
An APS Inconsistent (APSCINCON) alarm means that an inconsistent APS byte is present. The SONET overhead contains K1/K2 APS bytes that notify receiving equipment, such as the ONS 15327, to switch the SONET signal from a working to a protect path. An inconsistent APS code occurs when three consecutive frames do not contain identical APS bytes. Inconsistent APS bytes give the receiving equipment conflicting commands about switching.
Procedure: Clear the APSCINCON Alarm
Step 1 Look for other alarms, especially an LOS (OC-N) alarm (see page 2-83), an LOF (OC-N) alarm (see page 2-79), or an AIS condition (see page 2-16). Clearing these alarms clears the APSCINCON alarm.
Step 2 If an APSINCON alarm occurs with no other alarms, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.9 APSCM
•Major (MJ), Service Affecting (SA)
The APS Channel Mismatch (APSCM) alarm occurs when the ONS 15327 expects a working channel but receives a protection channel. In many cases, the working and protection channels are crossed and the protect channel is active. If the fibers are crossed and the working line is active, the alarm does not occur. The APSCM alarm occurs only on the ONS 15327 when bidirectional protection is used on OC-N cards in a 1+1 configuration.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the APSCM Alarm
Step 1 Verify that the working-card channel fibers are physically connected directly to the adjoining node's working-card channel fibers.
Step 2 If the fibers are correctly connected, verify that the protection-card channel fibers are physically connected directly to the adjoining node's protection-card channel fibers.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.10 APSCNMIS
•Major (MJ), Service Affecting (SA)
The APS Node ID Mismatch (APSCNMIS) alarm occurs when the source node ID contained in the K2 byte of the incoming APS channel is not present in the ring map. The APSCNMIS alarm might occur and clear when a BLSR is being provisioned. If so, you can disregard the temporary occurrence. If the APSCNMIS remains, the alarm clears when a K byte with a valid source node ID is received.
Procedure: Clear the APSCNMIS Alarm
Step 1 Complete the "Identify a Ring ID or Node ID Number" procedure to verify that each node has a unique node ID number.
Step 2 If the Node ID column contains any two nodes with the same node ID listed, record the repeated node ID.
Step 3 Click Close in the Ring Map dialog box.
Step 4 If two nodes have the same node ID number, complete the "Change a Node ID Number" procedure to change one node's ID number so that each node ID is unique.
Note If the node names shown in the network view do not correlate with the node IDs, log into each node and click the Provisioning > BLSR tabs. The BLSR window shows the node ID of the login node.
Note Applying and removing a lock out on a span causes the ONS 15327 to generate a new K byte. The APSCNMIS alarm clears when the node receives a K byte containing the correct node ID.
Step 5 If the alarm does not clear, use the "Lock Out a BLSR Span" procedure to lock out the span.
Step 6 Complete the "Clear a BLSR Span Lock Out" procedure to clear the lock out.

2.6.11 APSMM
•Minor (MN), Non-Service Affecting (NSA)
An APS Mode Mismatch failure (APSMM) alarm occurs when there is a mismatch of the protection switching schemes at the two ends of the span. If one node is provisioned for bidirectional switching, the node at the other end of the span must also be provisioned for bidirectional switching. If one end is provisioned for bidirectional and the other is provisioned for unidirectional, an APSMM alarm occurs in the ONS node that is provisioned for bidirectional. The APSMM alarm occurs in a 1+1 configuration.
Procedure: Clear the APSMM Alarm
Step 1 For the reporting ONS 15327, display the node view and verify the protection scheme provisioning:
a. Click the Provisioning > Protection tabs.
b. Choose the 1+1 protection group configured for the OC-N cards.

2.6.29 BKUPMEMP
•Critical (CR), Non-Service Affecting (NSA)
The Primary Non-Volatile Backup Memory Failure (BKUPMEMP) alarm refers to a problem with the XTC card's Flash memory. The alarm occurs when the XTC card is in use and has one of four problems: the Flash manager fails to format a Flash partition; the Flash manager fails to write a file to a Flash partition; there is a problem at the driver level, or the code volume fails the cyclic redundancy check (CRC). CRC is a method to verify for errors in data transmitted to the XTC.
The BKUPMEMP alarm can also cause the EQPT alarm (see page 2-49). If the EQPT alarm is caused by BKUPMEMP, complete the following procedure to clear the BKUPMEMP and the EQPT alarm.
Caution It can take up to 30 minutes for software to be updated on a standby XTC card.
Procedure: Clear the BKUPMEMP Alarm
Step 1 Verify that both XTC cards are powered and enabled by confirming lighted ACT/STBY LEDs on the XTC cards.
Step 2 If both XTC cards are powered and enabled, reset the active XTC card to it standby and make the standby XTC card active. Complete the "Reset the Active XTC Card in CTC" procedure.
Verify that the active card you reset is now standby. The ACT/STBY LED of this card should be amber, and the newly active XTC card LED should be green.
Step 3 If the XTC you reset does not reboot successfully, or the alarm has not cleared, call TAC (1-800-553-2447). If the TAC technician tells you to reseat the card, complete the "Remove and Reinsert (Reseat) the Standby XTC" procedure on page 3-3. If the TAC technician tells you to remove the card and reinstall a new one, follow the "Physically Replace a Card" procedure.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
2.6.30 BLSROSYNC
•Major (MJ), Service Affecting (SA)
The BLSR Out Of Synchronization (BLSROSYNC) alarm is caused when you attempt to add or delete a circuit and a node on a working ring loses its DCC connection because all transmit and receive fiber has been removed. CTC cannot generate the ring table and causes the BLSROSYNC alarm.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Procedure: Clear the BLSROSYNC Alarm
Step 1 Reestablish cabling continuity to the node reporting the alarm.
When the DCC is established between the node and the rest of the BLSR, it becomes visible to the BLSR and should be able to function on the circuits.
Step 2 If alarms occur when you have provisioned the DCCs, see the "EOC" section.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.31 CARLOSS (EQPT)
•Major (MJ), Service Affecting (SA)
A Carrier Loss on the LAN Equipment (CARLOSS) alarm occurs when the ONS 15327 and the workstation hosting CTC do not have a TCP/IP connection. The problem involves the LAN or data circuit used by the RJ-45 (LAN) connector on the XTC card. The CARLOSS alarm does not involve an Ethernet circuit connected to an Ethernet port. The problem is in the connection and not CTC or the ONS 15327.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the CARLOSS (EQPT) Alarm
Step 1 Verify connectivity by pinging the ONS 15327 that is reporting the alarm:
a. If you are using a Microsoft Windows operating system, from the Start Menu choose Programs > Accessories > Command Prompt.
b. If you are using a Sun Solaris operating system, from the Common Desktop Environment (CDE) click the Personal Application tab and click Terminal.
c. For both the Sun and Microsoft operating systems, at the prompt type:
ping [ONS 15327 IP address]
For example, ping 192.1.0.2.
If the workstation has connectivity to the ONS 15327, it shows a "reply from [IP Address]" after the ping. If the workstation does not have connectivity, a "Request timed out" message appears.
Step 2 If the ping is successful, an active TCP/IP connection exists. Restart CTC:
a. Exit from CTC.
b. Reopen the browser.
c. Log into CTC.
Step 3 Verify that the straight-through (Category 5) LAN cable is properly connected and attached to the correct port.
Step 4 If the straight-through (Category 5) LAN cable is properly connected and attached to the port, verify that the cable connects the card to another Ethernet device and is not misconnected to an OC-N card.
Step 5 If you are unable to establish connectivity, replace the straight-through cable with a new known-good cable.
Step 6 If you are unable to establish connectivity, perform standard network or LAN diagnostics. For example, trace the IP route, verify cable continuity, and troubleshoot any routers between the node and CTC.
Step 7 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.32 CARLOSS (E Series)
•Major (MJ), Service Affecting (SA)
A Carrier Loss alarm on the LAN E-series Ethernet (traffic) card is the data equivalent of an LOS (OC-N) alarm (see page 2-83). The Ethernet card has lost its link and is not receiving a valid signal. The most common causes of the CARLOSS alarm are a disconnected cable or an improperly installed Ethernet card. Ethernet card ports must be enabled (in service, IS) for CARLOSS to occur. CARLOSS is declared after no signal is received for approximately 2.5 seconds.
The CARLOSS alarm also occurs after a node database is restored. After restoration, the alarm clears in approximately 30 seconds after the node reestablishes Spanning Tree Protocol (STP). The database restoration circumstance applies to the E-series Ethernet cards but not the G1000-2 card, because the G1000-2 card does not use STP and is unaffected by STP reestablishment.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the CARLOSS (E-Series) Alarm
Step 1 Verify that the straight-through (Category 5) LAN cable is properly connected and attached to the correct port.
Step 2 If the straight-through (Category 5) LAN cable is properly connected and attached to the port, verify that the cable connects the card to another Ethernet device and is not misconnected to an OC-N card.
Step 3 If no misconnection to an OC-N card exists, verify that the transmitting device is operational. If not, troubleshoot the device.
Step 4 If the alarm does not clear, use an Ethernet test set to determine whether a valid signal is coming into the Ethernet port.
For specific procedures to use the test set equipment, consult the manufacturer.
Step 5 If a valid Ethernet signal is not present and the transmitting device is operational, replace the straight-through (Category 5) LAN cable connecting the transmitting device to the Ethernet port.
Step 6 If a valid Ethernet signal is present, complete the "Remove and Reinsert (Reseat) a Card" procedure for the Ethernet (traffic) card.
Step 7 If the alarm does not clear, complete the "Physically Replace a Card" procedure for the Ethernet (traffic) card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 8 If a CARLOSS alarm repeatedly appears and clears, use the following steps to examine the layout of your network to determine whether the Ethernet circuit is part of an Ethernet manual cross-connect.
Step 9 If the reporting Ethernet circuit is part of an Ethernet manual cross-connect, then the reappearing alarm might be a result of mismatched STS circuit sizes in the setup of the manual cross-connect. Perform the following steps unless the Ethernet circuit is part of a manual cross-connect:
a. Right-click anywhere in the row of the CARLOSS alarm.
b. Click the Select Affected Circuits dialog box that appears.
c. Record the information in the Type and Size columns of the highlighted circuit.
d. From the examination of the layout of your network, determine which ONS 15327 and card host the Ethernet circuit at the other end of the Ethernet manual cross-connect:
•Log into the ONS 15327 at the other end of the Ethernet manual cross-connect.
•Double-click the Ethernet card that is part of the Ethernet manual cross-connect.
•Click the Circuits tab.
•Record the information in the Type and Size columns of the circuit that is part of the Ethernet manual cross-connect. The Ethernet manual cross-connect circuit connects the Ethernet card to an OC-N card at the same node.
e. Determine whether the two Ethernet circuits on each side of the Ethernet manual cross-connect have the same circuit size from the circuit size.
f. If one of the circuit sizes is incorrect, complete the "Delete a Circuit" procedure and reconfigure the circuit with the correct circuit size. For more information, refer to the Cisco ONS 15327 Procedure Guide.
Step 10 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.33 CARLOSS (G Series)
•Major (MJ), Service Affecting (SA)
A Carrier Loss alarm on the LAN G-Series Ethernet (traffic) card is the data equivalent of an LOS (OC-N) alarm (see page 2-83). The Ethernet card has lost its link and is not receiving a valid signal.
CARLOSS on the G1000-2 card is caused by one of two situations:
•The G1000-2 port reporting the alarm is not receiving a valid signal from the attached Ethernet device. The CARLOSS can be caused by an improperly connected Ethernet cable or a problem with the signal between the Ethernet device and the G1000-2 port.
•If a problem exists in the end-to-end path (including possibly the far-end G1000-2 card), it causes the reporting G1000-2 card to turn off the Gigabit Ethernet transmitter. Turning off the transmitter typically causes the attached device to turn off its link laser, which results in a CARLOSS on the reporting G1000-2 card. The root cause is the problem in the end-to-end path. When the root cause is cleared, the far-end G1000-2 port turns the transmitter laser back on and clears the CARLOSS on the reporting card. If a turned-off transmitter causes the CARLOSS alarm, other alarms such as a TPTFAIL (G-Series) alarm (see page 2-119) or OC-N alarms or conditions on the end-to-end path normally accompany the CARLOSS (G-Series) alarm.
Refer to the Cisco ONS 15327 Reference Manual for a description of the G1000-2 card's end-to-end Ethernet link integrity capability. Also see the "TRMT" section for more information about alarms that occur when a point-to-point circuit exists between two G1000-2 cards.
Ethernet card ports must be enabled (in service, IS) for CARLOSS to occur. CARLOSS is declared after no signal is received for approximately 2.5 seconds.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the CARLOSS (G Series) Alarm
Step 1 Verify that the straight-through (Category 5) LAN cable is properly connected and attached to the correct port.
Step 2 If the straight-through (Category 5) LAN cable is correctly connected and attached, verify that the cable connects the card to another Ethernet device and is not misconnected to an OC-N card.
Step 3 If no misconnection to the OC-N card exists, verify that the attached transmitting Ethernet device is operational. If not, troubleshoot the device.
Step 4 If the alarm does not clear, use an Ethernet test set to determine that a valid signal is coming into the Ethernet port.
For specific procedures to use the test set equipment, consult the manufacturer.
Step 5 If a valid Ethernet signal is not present and the transmitting device is operational, replace the straight-through (Category 5) LAN cable connecting the transmitting device to the Ethernet port.
Step 6 If the alarm does not clear and link autonegotiation is enabled on the G1000-2 port, but the autonegotiation process fails, the G1000-2 turns off its transmitter laser and reports a CARLOSS alarm. If link autonegotiation has been enabled for the port, verify whether there are conditions that could cause autonegotiation to fail:
a. Confirm that the attached Ethernet device has autonegotiation enabled and is configured for compatibility with the asymmetric flow control on the G1000-2.
b. Confirm that the attached Ethernet device configuration allows reception of flow control frames.
Step 7 If the alarm does not clear, disable and reenable the Ethernet port to attempt to remove the CARLOSS condition. (The autonegotiation process restarts.)
Step 8 If the alarm does not clear and a TPTFAIL (G-Series) alarm (see page 2-119) alarm is also reported, complete the "Clear the TPTFAIL (G-Series) Alarm" procedure. If the TPTFAIL alarm is not reported, continue to the next step.
Note When the CARLOSS and the TPTFAIL alarms are reported, the reason for the condition might be the G1000-2's end-to-end link integrity feature taking action on a remote failure indicated by the TPTFAIL alarm.
Step 9 If the TPTFAIL alarm was not reported, verify whether a terminal loopback has been provisioned on the port:
a. In node view, click the card to go to card view.
b. Click the Conditions tab and the Retrieve Conditions button.
c. If LPBKTERMINAL is listed for the port, a loopback is provisioned. Go to Step 10. If in service (IS) is listed, go to Step 11.
Step 10 If a loopback was provisioned, complete the "Clear a Loopback" procedure.
On the G1000-2 card, provisioning a terminal loopback causes the transmit laser to turn off. If an attached Ethernet device detects the loopback as a loss of carrier, the attached Ethernet device shuts off the transmit laser to the G1000-2 card. Terminating the transmit laser could raise the CARLOSS alarm because the loopbacked G1000-2 port detects the termination.
If the does not have a LPBKTERMINAL condition, continue to Step 11.
Step 11 If a CARLOSS alarm repeatedly appears and clears, the reappearing alarm might be a result of mismatched STS circuit sizes in the setup of the manual cross-connect. Perform the following steps if the Ethernet circuit is part of a manual cross-connect:
Note An Ethernet manual cross-connect is used when another vendors' equipment sits between ONS 15327s, and the OSI/TARP-based equipment does not allow tunneling of the ONS 15327 TCP/IP-based DCC. To circumvent a lack of continuous DCC, the Ethernet circuit is manually cross connected to an STS channel riding through the non-ONS network.
a. Right-click anywhere in the row of the CARLOSS alarm.
b. Right-click or left-click the Select Affected Circuits dialog box.
c. Record the information in the Type and Size columns of the highlighted circuit.
d. Examine the layout of your network and determine which ONS 15327 and card host the Ethernet circuit at the other end of the Ethernet manual cross-connect:
•Log into the ONS 15327 at the other end of the Ethernet manual cross-connect.
•Double-click the Ethernet (traffic) card that is part of the Ethernet manual cross-connect.
•Click the Circuits tab.
•Record the information in the Type and Size columns of the circuit that is part of the Ethernet manual cross-connect. The cross-connect circuit connects the Ethernet (traffic) card to an OC-N card at the same node.
e. Determine whether the two Ethernet circuits on each side of the Ethernet manual cross-connect have the same circuit size from the circuit size information you recorded.
f. If one of the circuit sizes is incorrect, complete the "Delete a Circuit" procedure and reconfigure the circuit with the correct circuit size. Refer to the Cisco ONS 15327 Procedure Guide for detailed procedures to create circuits.
Step 12 If a valid Ethernet signal is present, complete the "Remove and Reinsert (Reseat) a Card" procedure.
Step 13 If the alarm does not clear, complete the "Physically Replace a Card" procedure for the Ethernet (traffic) card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 14 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

2.6.44 DS3-MISM
•Not Alarmed (NA), Non-Service Affecting (NSA)
The DS-3 Frame Format Mismatch (DS3-MISM) condition indicates a DS-1 frame format mismatch on a signal transiting the XTC-28-3 card. The condition occurs when the provisioned line type and incoming signal frame format type do no match. For example, if the line type is set to D4 for a DS-1 transiting the XTC-28-3 card, and the incoming signal's line type format is detected as unframed, then the ONS 15327 reports a DS3-MISM condition.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Note You can only provision DS-1 line frame format on the XTC-28-3 card. DS-3 line format is not provisionable.
Procedure: Clear the DS3-MISM Condition
Step 1 Display the CTC card view for the reporting (active) XTC-28-3 card.
Step 2 Click the Provisioning > DS1 > Line tabs.
Step 3 For the row on the appropriate port, verify that the Line Type column is set to match the expected incoming signal (ESF, D4, or unframed).

Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Note If a circuit shows an incomplete state when the EOC alarm is raised, it occurs when the logical circuit is in place and will be able to carry traffic when the DCC termination issue is resolved. You do not need to delete the circuit when troubleshooting this alarm.
Procedure: Clear the EOC Alarm
Step 1 If an LOS (DS-1) alarm (see page 2-81) is also reported, complete the "Clear the LOS (DS-1) Alarm" procedure.
Step 2 If the alarm does not clear on the reporting node, verify the physical connections between the cards and the fiber-optic cables that are configured to carry DCC traffic.
Step 3 If the physical connections are correct and configured to carry DCC traffic, verify that both ends of the fiber span have in-service (IS) ports by checking that the ACT LED on each OC-N card is illuminated.
Step 4 If the ACT LEDs on OC-N cards are illuminated, complete the "Verify or Create Node DCC Terminations" procedure to verify that the DCC is provisioned for the ports at both ends of the fiber span.
Step 5 Repeat Step 4 at the adjacent nodes.
Step 6 If DCC is provisioned for the ends of the span, verify that the OC-N port is active and in service:
a. Confirm that the OC-N card shows a green LED in CTC or on the physical card.
A green LED indicates an active card. An amber LED indicates a standby card.
b. To determine whether the OC-N port is in service, double-click the card in CTC to display the card view.
c. Click the Provisioning > Line tabs.
d. Verify that the State column lists the port as in service (IS).
e. If the State column lists the port as OOS, click the column and click IS from the drop-down menu. Click Apply.
Step 7 If the OC-N card is in service, use an optical test set to verify whether signal failures are present on fiber terminations.
For specific procedures to use the test set equipment, consult the manufacturer.
Caution Using an optical test set disrupts service on the OC-N (traffic) card. It might be necessary to externally switch traffic carrying circuits over to a protection path.
Step 8 If no signal failures on terminations exist, measure power levels to verify that the budget loss is within the parameters of the receiver. See the "Optical Card Transmit and Receive Levels" section on page 1-77.
Step 9 If budget loss is within parameters, ensure that fiber connectors are securely fastened and properly terminated. For more information refer to the "Install the Fiber-Optic Cables" procedure in the Cisco ONS 15327 Procedure Guide.
Step 10 If fiber connectors are properly fastened and terminated, complete the "Reset the Active XTC Card in CTC" procedure.
Verify that the active card you reset is now standby. The ACT/STBY LED of this card should be amber, and the newly active XTC card LED should be green.
If the alarm clears when the ONS 15327 switches to the standby XTC, the user can assume that the original active XTC is the cause of the alarm.
Step 11 If the XTC replacement does not clear the alarm, delete the problematic DCC termination:
a. Click the Provisioning > SONET DCC tabs.
b. Highlight the problematic DCC termination.
c. Click Delete.
d. Click Yes at confirmation dialog box.
Step 12 Recreate the DCC termination using the "Provision SONET DCC Terminations" procedure in the Cisco ONS 15327 Procedure Guide.
Step 13 Verify that both ends of the DCC have been recreated at the optical ports.
Step 14 If the alarm has not cleared, call TAC (1-800-553-2447). If the TAC technician tells you to reseat the card, complete the "Remove and Reinsert (Reseat) the Standby XTC" procedure on page 3-3. If the TAC technician tells you to remove the card and reinstall a new one, follow the "Physically Replace a Card" procedure.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
2.6.50 EQPT
•Critical (CR), Service Affecting (SA)
An Equipment Failure (EQPT) alarm indicates that a hardware failure has occurred on the reporting card.
If the EQPT alarm occurs with a BKUPMEMP alarm, see the "BKUPMEMP" section. The BKUPMEMP procedure also clears the EQPT alarm.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the EQPT Alarm
Step 1 Complete the "Reset a Traffic Card in CTC" procedure for the reporting card:
•While the card resets, the FAIL LED on the physical card blinks and turns off.
•While the card resets, the white LED with the letters "LDG" appears on the reset card in CTC.
Step 2 Verify that the reset is complete and error-free:
•No new alarms appear in the Alarms window in CTC.
•If you are looking at the physical ONS 15327, the ACT/STBY LED is illuminated.
•If you are looking at the node view of the ONS 15327, an amber LED depiction with "Sby" has replaced the white "LDG" depiction on the card in CTC.
Step 3 If the CTC reset does not clear the alarm, complete the "Remove and Reinsert (Reseat) a Card" procedure.
Step 4 If you reinsert a high-speed card, verify the following LED behavior:
•The FAIL LED blinks for approximately 30 seconds.
•All LEDs blink once and turn off.
•The ACT/STBY LED is green (active).
Step 5 If the physical reseat of the card fails to clear the alarm, complete the "Physically Replace a Card" procedure.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 6 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.51 EQPT-MISS
•Critical (CR), Service Affecting (SA)
The Replaceable Equipment or Unit Missing (EQPT-MISS) alarm is reported against the fan-tray assembly unit. It indicates that the replaceable fan-tray assembly is missing or not fully inserted.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the EQPT-MISS Alarm
Step 1 If the alarm is reported against the fan, verify that the fan-tray assembly is present.
Step 2 If the fan-tray assembly is present, complete the "Remove and Reinsert Fan-Tray Assembly" procedure.
Step 3 If no fan-tray assembly is present, obtain a fan-tray assembly and complete the "Install the Fan-Tray Assembly" procedure in the Cisco ONS 15327 Procedure Guide.
Step 4 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.52 E-W-MISMATCH
•Major (MJ), Service Affecting (SA)
A Procedural Error Misconnect East/West Direction (E-W-MISMATCH) alarm occurs when nodes in a ring have an east slot misconnected to another east slot or a west slot misconnected to another west slot. In most cases, the user did not connect the fibers correctly, or the ring provisioning plan was flawed. You can physically reconnect the cable to the correct slots to clear the E-W-MISMATCH alarm. Alternately, you can delete and recreate the span in CTC to change the west line and east line designations. The CTC method clears the alarm, but might change the traditional east-west node connection pattern of the ring.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Note The E-W-MISMATCH alarm also appears during the initial set up of a ring with its East-West slots configured correctly. If the alarm appears during the initial setup, the alarm clears itself shortly after the ring setup is complete.
Note The lower numbered slot at a node is traditionally labeled as the west slot and the higher numbered slot is labeled as the east slot. For example, Slot 1 is west and Slot 4 is east.
Note The physical switch procedure is the recommend method of clearing the E-W-MISMATCH alarm. The physical switch method reestablishes the logical pattern of connection in the ring. However, you can also use CTC to recreate the span and identify the misconnected slots as east and west. The CTC method is useful when the misconnected node is not geographically near the troubleshooter.
Procedure: Clear the E-W-MISMATCH Alarm with a Physical Switch
Step 1 Diagram the ring setup, including nodes and spans, on a piece of paper or white board.
Step 2 In node view, click View > Go to Network View.
Step 3 Label each of the nodes on the diagram with the same name that appears on the network map.
Step 4 Right-click each span to reveal the node name/slot/port for each end of the span.
Step 5 Label the span ends on the diagram with the same information. For example, with Node1/Slot12/Port1 to Node2/Slot6/Port1 (2F BLSR OC48, Ring ID=0), label the end of the span that connects Node 1 and Node 2 at the Node 1 end as Slot 12/Port 1. Label the Node 2 end of that same span Slot 6/ Port 1.
Step 6 Repeat Steps 4 and 5 for each span on your diagram.
Step 7 Label the highest slot at each node east and the lowest slot at each node west.
Step 8 Examine the diagram. You should see a clockwise pattern of west slots connecting to east slots for each span.
Step 9 If any span has an east-to-east or west-to-west connection, physically switching the fiber connectors from the card that does not fit the pattern to the card that continues the pattern should clear the alarm.
Step 10 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
Procedure: Clear the E-W-MISMATCH Alarm in CTC
Step 1 Log into the misconnected node. A misconnected node has both ring fibers connecting it to its neighbor nodes misconnected.
Step 2 Click the Maintenance > BLSR tabs.
Step 3 From the row of information for the fiber span, complete the "Identify a Ring ID or Node ID Number" procedure to identify the node ID, ring ID, and the slot and port in the East Line list and West Line columns. Record the information.
Step 4 Click View > Go to Network View.
Step 5 Delete and recreate the BLSR:
a. Click the Provisioning > BLSR tabs.
b. Click the row from Step 3 to select it and click Delete.

Step 9 Click OK.
Step 10 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.53 EXCCOL
•Minor (MN), Non-Service Affecting (NSA)
The Excess Collisions on the LAN (EXCCOL) alarm indicates that too many collisions are occurring between data packets on the network management LAN, and communications between the ONS 15327 and CTC might be affected. The network management LAN is the data network connecting the workstation running the CTC software to the XTC card. The problem causing the alarm is external to the ONS 15327.
Troubleshoot the network management LAN connected to the XTC card for excess collisions. You might need to contact the system administrator of the network management LAN to accomplish the following steps.
Procedure: Clear the EXCCOL Alarm
Step 1 Verify that the network device port connected to the XTC card has a flow rate set to 10 Mb, half-duplex.
Step 2 If the port has the correct flow rate and duplex setting, troubleshoot the network device connected to the XTC card and the network management LAN.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.54 EXERCISE-RING-REQ
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Exercise Request on Ring (EXERCISE-RING-REQ) condition occurs when optical (traffic) cards in two-fiber BLSRs are tested using the EXERCISE RING command.
Note EXERCISE-RING-REQ is an informational condition. It does not require troubleshooting.
2.6.55 EXERCISE-SPAN-REQ
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Exercise Request on Span (EXERCISE-SPAN-REQ) condition occurs when optical (traffic) cards in a BLSR are tested using the EXERCISE SPAN command.
Note EXERCISE-SPAN-REQ is an informational condition. It does not require troubleshooting.
2.6.56 EXT

Step 2 Perform your standard operating procedure for the environmental condition.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.57 EXTRA-TRAF-PREEMPT
•Major (MJ), Service Affecting (SA)
An Extra Traffic Preempted (EXTRA-TRAF-PREEMPT) alarm occurs on OC-N cards in two-fiber BLSRs because low-priority traffic directed to the protect system has been preempted by a working system protection switch.
Procedure: Clear the EXTRA-TRAF-PREEMPT Alarm
Step 1 Verify that the protection switch has occurred by checking the Conditions tab.
Step 2 If a ring switch has occurred, clear the alarm on the working system by following the appropriate alarm procedure in this chapter.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.58 FAILTOSW
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Failure to Switch to Protection (FAILTOSW) condition occurs when a working electrical or optical (traffic) card cannot switch to the protect card in a protection group, because another working electrical or optical card with a higher-priority alarm has switched to the protect card.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the FAILTOSW Condition
Step 1 Look up and troubleshoot the higher-priority alarm. Clearing the higher-priority condition frees the 1:N electrical card or 1+1 optical card and clears the FAILTOSW.
Step 2 If the condition does not clear, replace the working card that is reporting the higher priority alarm by following the "Physically Replace a Card" procedure. This card is the working optical card using the 1+1 protection and not reporting FAILTOSW.
Replacing the working electrical card that is reporting the higher-priority alarm allows traffic to revert to the working slot and the card reporting the FAILTOSW to switch to the protect card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 3 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.59 FAILTOSW-PATH
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Fail to Switch to Protection Path (FAILTOSW-PATH) condition occurs when the working path does not switch to the protection path on a UPSR. Common causes of the FAILTOSW-PATH alarm include a missing or defective protection card or a lock out set on one of the UPSR nodes.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the FAILTOSW-PATH Condition in a UPSR Configuration
Step 1 Look up and clear the higher priority alarm. Clearing this alarm frees the standby card and clears the FAILTOSW-PATH condition.
Note A higher-priority alarm is an alarm raised on the working DS-N card using the 1:N card protection group. The working DS-N card is reporting an alarm but not reporting a FAILTOSW condition.
Step 2 If the condition does not clear, replace the active OC-N card that is reporting the higher priority alarm. Complete the "Physically Replace a Card" procedure. Replacing the active OC-N card that is reporting the higher priority alarm allows traffic to revert to the active slot. Reverting frees the standby card, which can then take over traffic from the card reporting the lower priority alarm and the FAILTOSW-PATH alarm.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 3 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.60 FAILTOSWR
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Fail to Switch to Protection Ring (FAILTOSWR) condition occurs when a ring switch did not complete because of internal APS problems.
FAILTOSWR clears when one of the following actions occurs: a higher priority event, such as an external switch command occurs, the next ring switch succeeds, or the cause of the APS switch [such as an SD condition (see page 2-104) or an SF condition (see page 2-106)] clears.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.

The Loss of Frame (LOF) BITS alarm occurs when a port on the XTC BITS input detects an LOF on the incoming BITS timing reference signal. LOF indicates that the receiving ONS 15327 has lost frame delineation in the incoming data.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Note The procedure assumes that the BITS timing reference signal is functioning properly. It also assumes that the alarm is not appearing during node turn up.
Procedure: Clear the LOF (BITS) Alarm
Step 1 Verify that the framing and line coding match between the BITS input and the XTC:
a. In node view or card view, note the slot and port reporting the alarm.
b. Find the framing and coding formats of the external BITS timing source. The formats should be in the user documentation for the external BITS timing source or on the timing source itself.
c. Click the Provisioning > Timing tabs to display the General Timing window.
d. Verify that the Coding field matches the coding of the BITS timing source (B8ZS or AMI).
e. If the coding does not match, click Coding and choose the appropriate coding from the drop-down menu.
f. Verify that the Framing field matches the framing of the BITS timing source, either SF (D4) or ESF.
g. If the framing does not match, click Framing and choose the appropriate framing from the drop-down menu.
Note On the timing subtab, the B8ZS coding field is normally paired with ESF in the Framing field, and the AMI coding field is normally paired with SF (D4) in the Framing field.
Step 2 If the alarm does not clear when the line framing and line coding match between the BITS input and the XTC, complete the "Physically Replace a Card" procedure for the XTC card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.

2.6.107 LOF (OC-N)
•Critical (CR), Service Affecting (SA)
The OC-N LOF alarm occurs when a port on the reporting OC-N card has an LOF condition. LOF indicates that the receiving ONS 15327 has lost frame delineation in the incoming data. LOF occurs when the SONET overhead loses a valid framing pattern for 3 milliseconds. Receiving two consecutive valid A1/A2 framing patterns clears the alarm.
LOF on an OC-N card is sometimes an indication that the OC-N card reporting the alarm expects a specific line rate and the input line rate source does not match the input line rate of the optical receiver.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the LOF (OC-N) Alarm
Step 1 Verify cabling continuity to the port reporting the alarm.
Step 2 If cabling continuity is correct, clean the fiber connectors according to site practice. If no site practice exists, complete the procedure in the Cisco ONS 15327 Procedure Guide.
Step 3 If the alarm does not clear, see the "Network Troubleshooting Tests" section on page 1-2 to isolate the fault causing the LOF alarm.

2.6.108 LOP-P
•Critical (CR), Service Affecting (SA)
A Loss of Pointer Path (LOP-P) alarm indicates that the SONET path pointer in the overhead has been lost. LOP occurs when valid H1/H2 pointer bytes are missing from the overhead. Receiving equipment monitors the H1/H2 pointer bytes to locate the SONET payload. An LOP-P alarm occurs when eight, nine, or ten consecutive frames do not have valid pointer values. The alarm clears when three consecutive valid pointers are received.
The LOP-P alarm can occur when the received payload does not match the provisioned payload. The alarm is caused by a circuit type mismatch on the concatenation facility. For example, if an STS-1 is sent across a circuit provisioned for STS-3c, an LOP-P alarm occurs.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the LOP-P Alarm
Step 1 In node view, click the Circuits tab and view the alarmed circuit.
Step 2 Verify that the correct circuit size is listed in the Size column. If the size is different from what is expected, such as an STS 3c instead of an STS1, this will cause the alarm.
Step 3 If you have been monitoring the circuit with optical test equipment, a mismatch between the provisioned circuit size and the size expected by the test set can cause this alarm. Ensure that the test set monitoring is set up for the same size as the circuit provisioning.
For instructions to use the optical test set, consult the manufacturer.
Step 4 If you have not been using a test set, or if the test set is correctly set up, the error is in the provisioned CTC circuit size. Complete the "Delete a Circuit" procedure.
Step 5 Recreate the circuit for the correct size. For instructions, see the Cisco ONS 15327 Procedure Guide.
Step 6 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

Step 1 Complete the "Reset the Active XTC Card in CTC" procedure.
Verify that the active card you reset is now standby. The ACT/STBY LED of this card should be amber, and the newly active XTC card LED should be green.
Step 2 If the reset card has not rebooted successfully, or the alarm has not cleared, call TAC (1-800-553-2447). If the TAC technician tells you to reseat the card, complete the "Remove and Reinsert (Reseat) the Standby XTC" procedure on page 3-3. If the TAC technician tells you to remove the card and reinstall a new one, follow the "Physically Replace a Card" procedure.
Step 3 If the MFGMEM alarm continues to report after replacing the XTC cards, the problem is with the EEPROM.
Step 4 If the MFGMEM is reported from the fan-tray assembly, obtain a fan-tray assembly and complete the "Replace the Fan-Tray Assembly" procedure on page 3-1.
Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.131 PDI-P
•Not Alarmed (NA), Non-Service Affecting (NSA)
A PDI Path (PDI-P) condition indicates a signal label mismatch failure (SLMF). An invalid signal label C2 byte in the SONET path overhead causes an SLMF. The C2 byte tells the equipment what the SONET payload envelope contains and how it is constructed. It enables a SONET device to transport multiple types of services.
The ONS 15327 encounters an SLMF when the payload, such as an ATM, does not match what the signal label is reporting. An AIS condition (see page 2-16) often accompanies the PDI-P condition. If the PDI-P is the only condition reported with the AIS condition (see page 2-16), clear the PDI-P condition to clear the AIS condition. PDI-P can also occur during an upgrade, but usually clears itself and is not a valid condition.
A PDI-P condition reported on the port of an OC-N card supporting a G1000-2 card circuit might result from the end-to-end Ethernet link integrity feature of the G1000-2. If the link integrity is the cause, it typically is accompanied by an a TPTFAIL (G-Series) alarm (see page 2-119) or a CARLOSS (G Series) alarm (see page 2-33) reported against one or both Ethernet ports terminating the circuit. If TPTFAIL or CARLOSS are reported against one or both of the Ethernet ports, troubleshooting the accompanying alarm clears the PDI-P condition.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the PDI-P Condition
Step 1 Verify that all circuits terminating in the reporting card are in an active state:
a. Click the Circuits tab.
b. Verify that the State column lists the port as active.
c. If the State column lists the port as incomplete, wait up to ten minutes for the ONS 15327 to initialize fully. If the incomplete state does not change after full initialization, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
Step 2 After determining that the port is active, ensure that the signal source to the card reporting the alarm is working.
Step 3 If traffic is affected, complete the "Delete a Circuit" procedure.
Caution Deleting a circuit might affect traffic.
Step 4 Recreate the circuit with the correct circuit size. Refer to the Cisco ONS 15327 Procedure Guide for detailed procedures to create circuits.
Step 5 If circuit deletion and recreation does not clear the condition, verify that the far-end OC-N card providing STS payload to the reporting card is not errored.
Step 6 If the condition does not clear, confirm the cross-connect between the OC-N card and the reporting card.
Step 7 If the condition does not clear, clean the far-end optical fiber according to site practice. If no site practice exists, complete the procedure in the Cisco ONS 15327 Procedure Guide.
Step 8 If the condition does not clear, complete the "Physically Replace a Card" procedure for the optical/electrical cards.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.

2.6.132 PEER-NORESPONSE
•Major (MJ), Non-Service Affecting (NSA)
The Peer Card Not Responding (PEER-NORESPONSE) alarm is raised by the switch agent if either traffic card in a protection group does not receive a response to the peer status request message. PEER-NORESPONSE is a software failure and occurs at the task level, as opposed to a communication failure, which is a hardware failure between peer cards.
Procedure: Clear the PEER-NORESPONSE Alarm
Step 1 Complete the "Reset a Traffic Card in CTC" procedure for the protect card:
•While the card resets, the FAIL LED on the physical card blinks and turns off.
•While the card resets, the white LED with the letters "LDG" (loading) appears on the reset card in CTC.
Step 2 Verify that the reset is complete and error-free:
•No new alarms appear in the Alarms window in CTC.
•If you are looking at the physical ONS 15327, the ACT/STBY LED is illuminated.
•If you are looking at the node view of the ONS 15327, an amber LED depiction with "Sby" has replaced the white "LDG" depiction on the card in CTC.
Step 3 Complete the "Reset a Traffic Card in CTC" procedure for the working card:

Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.133 PLM-P
•Critical (CR), Service Affecting (SA)
A Payload Label Mismatch Path (PLM-P) alarm indicates that signal does not match its label. The condition occurs due to an invalid C2 byte value in the SONET path overhead.
For example, this alarm can occur when a card is expecting a 0 value in the C2 byte, but receives a 4 instead. This can occur on the XTC card when the card expects a DS-1 signal but receives a DS-3 signal. The DS-3 signal C2 byte value is 4, so this will cause a label mismatch and a PLM-P alarm.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the PLM-P Alarm
Step 1 Verify that all circuits terminating in the reporting card are active:
a. Click the Circuits tab.
b. Verify that the State column lists the port as active.
c. If the State column lists the port as incomplete, wait up to ten minutes for the ONS 15327 to initialize fully. If the incomplete state does not change after full initialization, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).

For specific procedures to use the test set equipment, consult the manufacturer.
Step 3 If traffic is being affected, complete the "Delete a Circuit" procedure.
Caution Deleting a circuit might affect traffic.
Step 4 Recreate the circuit with the correct circuit size. Refer to the Cisco ONS 15327 Procedure Guide for detailed procedures to create circuits.
Step 5 If the circuit deletion and recreation does not clear the alarm, verify the far-end OC-N card that provides STS payload to the XTC card.
Step 6 If the alarm does not clear, verify the cross-connect between the OC-N card and the XTC card.
Step 7 If the alarm does not clear, clean the far-end optical fiber according to site practice. If no site practice exists, complete the procedure in the Cisco ONS 15327 Procedure Guide.
Step 8 If the alarm does not clear, complete the "Physically Replace a Card" procedure for the reporting traffic card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 9 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.134 PLM-V
•Minor (MN), Service Affecting (SA)
A Payload Label Mismatch VT Layer (PLM-V) alarm indicates that the content of the V5 byte in the SONET overhead is inconsistent or invalid. PLM-V occurs when ONS nodes interoperate with equipment that performs bit-synchronous mapping for DS-1. ONS nodes use asynchronous mapping.
Procedure: Clear the PLM-V Alarm
Step 1 Verify that your signal source matches the signal allowed by the traffic card. For example, the traffic card does not allow VT6 or VT9 mapping.
Step 2 If the signal source matches the card, verify that the SONET VT path originator is sending the correct VT label value. You can find the SONET VT path originator using circuit provisioning steps.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.135 PRC-DUPID
•Major (MJ), Service Affecting (SA) for Ring
•Major (MJ), Non-Service Affecting (NSA) for NE
The Procedural Error Duplicate Node ID (PRC-DUPID) alarm indicates that two identical node IDs exist in the same ring. The ONS 15327 requires each node in the ring to have a unique node ID.
Procedure: Clear the PRC-DUPID Alarm
Step 1 Log into a node on the ring.
Step 2 Find the node ID by completing the "Identify a Ring ID or Node ID Number" procedure.
Step 3 Repeat Step 2 for all the nodes on the ring.
Step 4 If two nodes have an identical node ID number, complete the "Change a Node ID Number" procedure so that each node ID is unique.
Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.136 PROTNA
•Minor (MN), Non-Service Affecting (NSA)
The Protection Unit Not Available (PROTNA) alarm is caused by an OOS or failed protection card when an XTC that is provisioned as part of a protection group is not available. Unavailable protection can occur when a card is reset, but the alarm clears as soon as the card is back in service. The alarm clears if the device or facility is brought back in service.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the PROTNA Alarm
Step 1 If the PROTNA alarm occurs and does not clear, and if the alarm is raised against an XTC, ensure that there is a redundant control card installed and provisioned in the chassis.
Step 2 If the alarm is raised against a traffic card, verify whether the ports have been taken out of service:
a. In CTC, double-click the reporting card to display the card view (if the card is not a cross-connect card).
b. Click the Provisioning tab.
c. Click the State of any in-service ports.
d. Choose OOS to take the ports out of service.
Step 3 Complete the "Reset a Traffic Card in CTC" procedure for the reporting card:
•While the card resets, the FAIL LED on the physical card blinks and turns off.
•While the card resets, the white LED with the letters "LDG" appears on the reset card in CTC.
Step 4 Verify that the reset is complete and error-free:
•No new alarms appear in the Alarms window in CTC.
•If you are looking at the physical ONS 15327, the ACT/STBY LED is illuminated.
•If you are looking at the node view of the ONS 15327, an amber LED depiction with "Sby" has replaced the white "LDG" depiction on the card in CTC.
Step 5 If the alarm does not clear, complete the "Remove and Reinsert (Reseat) a Card" procedure for the reporting card.
Step 6 If you reinsert a high-speed card, verify the following LED behavior:
•The FAIL LED blinks for approximately 30 seconds.
•All LEDs blink once and turn off.
•The ACT/STBY LED is green (active).
Step 7 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.137 PWR-A
•Minor (MN), Non-Service Affecting (NSA)
An NE Power Failure at Connector A alarm indicates that the power is out of the specified 48 VDC input range and is either too high (overvoltage) or too low (undervoltage), requiring you to check the incoming power feed or separate power distribution equipment, or both. The PWR-A alarm may also be raised before actual loss of power in a discharging power plant problem and before full loss of incoming power.
Overvoltage or undervoltage can be caused by incoming DC power problems such as power rectifier failure, faulty power cabling, or a blown fuse.
Cisco encourages the use of separate DC power feeds from separate DC power plants or AC power rectifiers to ensure power redundancy to the feeds. Using a single DC power source for both MIC-A/PWR-A and MIC-B/PWR-B creates a risk through the single point of possible failure. Using dual power feeds removes this risk liability.
Warning Hazardous energy level available at the power source and power connection. Do not bridge across battery terminals or bridge battery terminal to ground; metal objects heat up and can cause serious burns or weld the metal object to the terminals.
Procedure: Clear the PWR-A Alarm
Step 1 Determine whether the PWR-A alarm is occurring alone or in conjunction with the PWR-B alarm, and determine whether MIC A and MIC B are using one single or two separate power supplies.
Step 2 If you are using separate power sources for the MIC A and MIC B power connectors and the PWR-A alarm occurs without the PWR-B alarm, inspect the incoming voltage to the MIC A connector using site practices. The alarm can be caused by problems such as power rectifier failure, faulty power cabling, or a blown fuse, and correct these issues. Solve these problems before continuing.
You can verify the power connection continuity and the power source output with a voltmeter using the procedures in the Cisco ONS 15327 Procedure Guide.
Step 3 If you are using a single power source for both the MIC A and MIC B cards and only the PWR-A alarm is occurring, an electrical cable continuity or connection problem may be to blame. Check for these problems and correct them if necessary.
Step 4 If you are using separate power sources for each MIC card and the PWR-A alarm occurs in conjunction with the PWR-B alarm, it is likely that both incoming power feeds or power plants are failing. Check for these problems according to site practice and correct as necessary.
Step 5 If you are using a single power source for both MIC cards and both the PWR-A and PWR-B alarms are raised, problems with both power feeds may be to blame, but a power plant failure is more likely. Check for these problems according to site practice and correct as necessary.
Step 6 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.138 PWR-B

Step 1 Determine whether the PWR-B alarm is occurring alone or in conjunction with the PWR-A alarm, and determine whether MIC A and MIC B are using one single or two separate power supplies.
Step 2 If you are using separate power sources for the MIC A and MIC B power connectors and the PWR-B alarm occurs without the PWR-A alarm, inspect the incoming voltage to the MIC B connector using site practices. The alarm can be caused by problems such as power rectifier failure, faulty power cabling, or a blown fuse, and correct these issues. Solve these problems before continuing.
You can verify the power connection continuity and the power source output with a voltmeter using the procedures in the Cisco ONS 15327 Procedure Guide.
Step 3 If you are using a single power source for both the MIC A and MIC B cards and only the PWR-B alarm is occurring, an electrical cable continuity or connection problem may be to blame. Check for these problems and correct them if necessary.
Step 4 If you are using separate power sources for each MIC card and the PWR-B alarm occurs in conjunction with the PWR-A alarm, it is likely that both incoming power feeds or power plants are failing. Check for these problems according to site practice and correct as necessary.
Step 5 If you are using a single power source for both MIC cards and both the PWR-A and PWR-B alarms are raised, problems with both power feeds may be to blame, but a power plant failure is more likely. Check for these problems according to site practice and correct as necessary.
Step 6 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.139 PWR-REDUN
•Minor (MN), Non-Service Affecting (NSA)
The Redundant Power Capability Lost (PWR-REDUN) alarm applies to cards that have two built-in fuses (such as newer optical cards). The alarm indicates that one of the fuses has blown and must be serviced. When this alarm occurs, the card's power redundancy is lost because only one card power connection can contact one of the redundant power supplies.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the PWR-REDUN Alarm

2.6.141 RCVR-MISS
•Major (MJ), Service Affecting (SA)
A Facility Termination Equipment Receiver Missing (RCVR-MISS) alarm occurs when the facility termination equipment detects an incorrect amount of impedance on its connector. Incorrect impedance usually occurs when a receive cable is missing from the XTC DS-1 port or a possible mismatch of equipment occurs.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Note DS-1s are four-wire circuits and need a positive (tip) and negative (ring) connection for both transmit and receive.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the RCVR-MISS Alarm

Note RING-SW-EAST is an informational condition. It does not require troubleshooting.
2.6.147 RING-SW-WEST
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Ring Switch is Active West Side (RING-SW-WEST) condition occurs when a ring switch occurs at the west side of a two-fiber BLSR. The condition clears when the switch is cleared.
Note RING-SW-WEST is an informational condition. It does not require troubleshooting.
2.6.148 SD
•Not Alarmed (NA), Non-Service Affecting (NSA)
A Signal Degrade (SD) condition occurs when the quality of the signal is so poor that the bit error rate on the incoming optical line passed the signal degrade threshold. Signal degrade is defined by Telcordia as a soft failure condition. SD and signal fail (SF) both monitor the incoming BER and are similar alarms, but SD is triggered at a lower bit error rate than SF.
The BER threshold on the ONS 15327 is user provisionable and has a range for SD from 10-9 to 10-5.
SD-L causes a switch from the working card to the protect card at the line (facility) level. A line or facility level SD condition travels on the B2 byte of the SONET overhead.
The SD condition clears when the BER level falls to one-tent h of the threshold level that triggered the condition. A BER increase is sometimes caused by a physical fiber problem, including a faulty fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the SD Condition
Step 1 Complete the "Verify BER Threshold Level" procedure.
Step 2 If the BER threshold is correct and at the expected level, use an optical test set to measure the power level of the line to ensure the level is within guidelines.
For specific procedures to use the test set equipment, consult the manufacturer.
Step 3 If the optical power level is correct, verify that optical receive levels are within the acceptable range.
Step 4 If receive levels are correct, clean the fibers at both ends according to site practice. If no site practice exists, complete the procedure in the Cisco ONS 15327 Procedure Guide.
Step 5 If the alarm does not clear, verify that single-mode fiber is used.
Step 6 If the fiber is the correct type, verify that a single-mode laser is used at the far-end node.
Step 7 If the problem does not clear, the transmitter at the other end of the optical line might be failing and require replacement.
Step 8 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.149 SD-L
•Not Alarmed (NA), Non-Service Affecting (NSA)
An SD Line condition is similar to an SD condition (see page 2-104). It applies to the line level of the SONET signal.
Procedure: Clear the SD-L Condition
Step 1 Complete the "Clear the SD Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.150 SD-P
•Not Alarmed (NA), Non-Service Affecting (NSA)
An SD Path (SD-P) condition is similar to an SD condition (see page 2-104) but it applies to the path (STS) layer of the SONET overhead. A path or ST-level SD alarm travels on the B3 byte of the SONET overhead.
For UPSR protected circuits, the BER threshold on the ONS 15327 is user provisionable and has a range for SD from 10-9 to 10-5. For BLSR 1+1 and unprotected circuits, the BER threshold value is not user provisionable and the error rate is hard-coded to 10-6.
On UPSR, an SD-P condition causes a switch from the working card to the protect card at the path (STS) level. On BLSR 1+1 or on unprotected circuits, an SD-P condition does not cause switching.
The BER increase that causes the alarm is sometimes caused by a physical fiber problem such as a poor fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
Signal degrade and signal fail both monitor the incoming BER and are similar alarms, but SD is triggered at a lower bit error rate than SF. SD causes the card to switch from working to protect. The SD alarm clears when the BER level falls to one-tenth of the threshold level that triggered the alarm.
Procedure: Clear the SD-P Condition
Step 1 Complete the "Clear the SD Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.151 SF
•Not Alarmed (NA), Non-Service Affecting (NSA)
A Signal Fail (SF) condition occurs when the quality of the signal is so poor that the BER on the incoming optical line passed the signal failure threshold. Signal failure is defined by Telcordia as a "hard failure" condition. The SD condition (see page 2-104) and SF both monitor the incoming BER error rate and are similar conditions, but SF is triggered at a higher BER than SD.
The BER threshold on the ONS 15327 is user provisionable and has a range for SF from 10-5 to 10-3.
SF-L causes a switch from the working card to the protect card at the line (facility) level. A line or facility level SF condition travels on the B2 byte of the SONET overhead.
SF causes a card to switch from working to protect at either the path or line level. The SF condition clears when the BER level falls to one-tenth of the threshold level that triggered the condition. A BER increase is sometimes caused by a physical fiber problem, including a poor fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
Procedure: Clear the SF Condition
Step 1 Complete the "Clear the SD Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.152 SF-L
•Not Alarmed (NA), Non-Service Affecting (NSA)
An SF Line (SF-L) condition is similar to an SF condition (see page 2-106) but it applies to the line layer of the signal.
Procedure: Clear the SF-L Condition
Step 1 Complete the "Clear the SD Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.153 SF-P
•Not Alarmed (NA), Non-Service Affecting (NSA)
An SF Path (SF-P) condition is similar to an SF condition (see page 2-106), but it applies to the path (STS) layer of the SONET overhead. A path or ST- level SD alarm travels on the B3 byte of the SONET overhead.
For UPSR circuits, the BER threshold on the ONS 15327 is user provisionable and has a range for SF from 10-5 to 10-3. For BLSR 1+1 or unprotected circuits, the BER threshold value is not user provisionable and the error rate is hard-coded to 10-3.
For UPSR, SF-P causes a switch from the working card to the protect card at the path (STS) level. For BLSR 1+1 or unprotected circuits, SF-P does not cause switching.
The BER increase that causes the alarm is sometimes caused by a physical fiber problem such as a poor fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
Procedure: Clear the SF-P Condition
Step 1 Complete the "Clear the SD Condition" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.154 SFTWDOWN
•Minor (MN), Non-Service Affecting (NSA)

No action is necessary. Wait for the transfer or the software download to complete. If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
Caution It can take up to 30 minutes for software to be updated on a standby XTC card.
Note SFTWDOWN is an informational alarm.
2.6.155 SNTP-HOST
•Minor (MN), Non-Service Affecting (NSA)
The Simple Network Timing Protocol (SNTP) Host Failure (SNTP-HOST) alarm indicates that an ONS node serving as an IP proxy for the other ONS nodes in the ring is not forwarding SNTP information to the other ONS nodes in the network. The forwarding failure can result from two causes, either the IP network attached to the ONS proxy node is experiencing problems, or the ONS proxy node itself is not functioning properly.
Procedure: Clear the SNTP-HOST Alarm
Step 1 Ping the SNTP host from a workstation in the same subnet to ensure that communication is possible within the subnet.
Step 2 If the ping fails, contact the network administrator who manages the IP network that supplies the SNTP information to the proxy and determine whether the network is experiencing problems which might affect the SNTP server/router connecting to the proxy ONS 15327.
Step 3 If no network problems exist, ensure that the ONS 15327 proxy is provisioned correctly:
a. In node view for the ONS node serving as the proxy, click the Provisioning > General tabs.
b. Ensure that the Use NTP/SNTP Server check box is checked.
c. If the Use NTP/SNTP Server check box is not checked, click the box.
d. Ensure that the Use NTP/SNTP Server field contains a valid IP address for the server.
Step 4 If proxy is correctly provisioned, refer to the Cisco ONS 15327 Reference Manual for more information about SNTP host.
Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).

2.6.157 SPAN-SW-WEST
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Span Switch is Active West Side (SPAN-SW-WEST) condition occurs when a span switch occurs at the west side of a BLSR span. The condition clears when the switch is cleared.
Note SPAN-SW-EAST is an informational condition. It does not require troubleshooting.
2.6.158 SQUELCH
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Ring Squelching Traffic (SQUELCH) condition occurs in a BLSR when a node that originates or terminates STS circuits fails or is isolated by multiple fiber cuts or maintenance FORCE RING commands. The isolation or failure of the node disables circuits that originate or terminate on the failed node. Squelch alarms appear on one or both of the nodes on either side of the isolated/failed node. The AIS-P condition (see page 2-16) also appears on all nodes in the ring except the isolated node.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the SQUELCH Condition
Step 1 Determine the isolated node:
a. In node view, click View > Go to Network View.
b. The grayed out node with red spans is the isolated node.
Step 2 Verify fiber continuity to the ports on the isolated node.
Step 3 If fiber continuity is correct, verify that the proper ports are in service (IS):
a. Confirm that the OC-N card shows a green LED in CTC or on the physical card.
A green LED indicates an active card. An amber LED indicates a standby card.
b. To determine whether the OC-N port is in service, double-click the card in CTC to display the card view.
c. Click the Provisioning > Line tabs.
d. Verify that the State column lists the port as in service (IS).
e. If the State column lists the port as OOS, click the column and choose IS. Click Apply.
Step 4 If the correct ports are in service, use an optical test set to verify that a valid signal exists on the line.
For specific procedures to use the test set equipment, consult the manufacturer. Test the line as close to the receiving card as possible.
Step 5 If the signal is valid, verify that the power level of the optical signal is within the optical card's receiver specifications. Refer to the Cisco ONS 15327 Reference Manual for card specifications.
Step 6 If the receiver levels are correct, ensure that the optical transmit and receive fibers are connected properly.
Step 7 If the connectors are correct, complete the "Physically Replace a Card" procedure for the OC-N card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 8 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.159 SSM-DUS
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Synchronization Status Message (SSM) Quality Changed to Do-Not-Use (DUS) condition occurs when the synchronization status message (SSM) quality level degrades to DUS or is manually changed to DUS.
The signal is often manually changed to DUS to prevent timing loops from occurring. Sending a DUS prevents the timing from being reused in a loop. The DUS signal can also be sent for line maintenance testing.
Note SSM-DUS is an informational condition. It does not require troubleshooting.
2.6.160 SSM-FAIL
•Minor (MN), Non-Service Affecting (NSA)
The SSM Failed (SSM-FAIL) alarm occurs when the synchronization status messaging received by the ONS 15327 fails. The problem is external to ONS 15327. The ONS 15327 is set up to receive SSM, but the timing source is not delivering valid SSM messages.
Procedure: Clear the SSM-FAIL Alarm

Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.177 SYNC-FREQ
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Synchronization Reference Frequency Out Of Bounds (SYNC-FREQ) condition is reported against any reference that is out of the bounds for valid references. The login node fails the reference and chooses another internal or external reference to use.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the SYNC-FREQ Condition
Step 1 Use an optical test set to verify the timing frequency of the line or BITS timing source and ensure that timing falls within the proper frequency.
For specific procedures to use the test set equipment, consult the manufacturer. For BITS, the proper timing frequency range is approximately -15 ppm to 15 ppm. For optical line timing, the proper frequency range is approximately -16 ppm to 16 ppm.
Step 2 If the reference source frequency is not outside of bounds, complete the "Physically Replace a Card" procedure for the XTC card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Note The active XTC takes up to 30 minutes to transfer the system software to the newly installed XTC. Software transfer occurs in instances where different software versions exist on the two cards. During the transfer operation, the LEDs on the XTC flash fail and then the active/standby LED flashes. When the transfer completes, the XTC reboots and goes into standby mode after approximately three minutes.
Step 3 If the SYNC-FREQ alarm continues to report after replacing the XTC card, log onto http://www.cisco.com/tac for more information or call TAC (1-800-553-2447).
2.6.178 SYNCPRI
•Minor (MN), Non-Service Affecting (NSA)
A Loss of Timing on Primary Reference (SYNCPRI) alarm occurs when the ONS 15327 loses the primary timing source (reference 1). The ONS 15327 uses three ranking timing references. The timing references are typically two BITS-level or line-level sources and an internal reference. If SYNCPRI occurs, the ONS 15327 should switch to its secondary timing source (reference 2). Switching to the secondary timing source also triggers a SWTOSEC condition (see page 2-115).
Procedure: Clear the SYNCPRI Alarm
Step 1 In node view, click the Provisioning > Timing tabs.
Step 2 Verify the current configuration for the REF-1 of the NE Reference.
Step 3 If the primary reference is a BITS input, complete the "Clear the LOS (BITS) Alarm" procedure.

2.6.180 SYNCTHIRD
•Minor (MN), Non-Service Affecting (NSA)
A Loss of Timing on Third Reference (SYNCTHIRD) alarm occurs when the ONS 15327 loses the third timing source (reference 3). The ONS 15327 uses three ranking timing references. The timing references are typically two BITS-level or line-level sources and an internal reference. If SYNCTHIRD occurs and the ONS 15327 uses an internal reference for source three, the XTC card might have failed. The ONS 15327 often reports either a FRNGSYNC condition (see page 2-70) or a HLDOVRSYNC alarm (see page 2-72) after a SYNCTHIRD alarm.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the SYNCTHIRD Alarm

Step 4 If the third timing source is an incoming port on the ONS 15327, complete the "Clear the LOS (OC-N) Alarm" procedure.
Step 5 If the third timing source uses the internal ONS 15327 timing, complete the "Reset the Active XTC Card in CTC" procedure.
Verify that the active card you reset is now standby. The ACT/STBY LED of this card should be amber, and the newly active XTC card LED should be green.
Step 6 If the reset card has not rebooted successfully, or the alarm has not cleared, call TAC (1-800-553-2447). If the TAC technician tells you to reseat the card, complete "Remove and Reinsert (Reseat) the Standby XTC" procedure on page 3-3. If the TAC technician tells you to remove the card and reinstall a new one, follow the "Physically Replace a Card" procedure.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
2.6.181 SYSBOOT
•Major (MJ), Service Affecting (SA)
The System Reboot (SYSBOOT) alarm indicates that new software is booting on the XTC card. No action is required. The alarm clears when all cards finish rebooting the new software. The reboot takes up to 10 minutes if the same version of software is present on both cards, or up to 30 minutes if the software is being updated from one XTC to the other.
If it does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
Note SYSBOOT is an informational alarm. It only requires troubleshooting if it does not clear.
2.6.182 TIM-P
•Critical (CR), Service Affecting (SA) for STSTERM
•Minor (MN), Non-Service Affecting (NSA) for STSMON
The Trace Identifier Mismatch (TIM) Path alarm occurs when the expected path trace string does not match the received path trace string. Path Trace Mode must be set to manual or Auto for the TIM-P alarm to occur.
In manual mode at the Path Trace window, the user types the expected string into the Current Expected String field for the receiving port. The string must match the string typed into the Transmit String field for the sending port. If these fields do not match, the login node raises the TIM-P alarm. In Auto mode on the receiving port, the card sets the expected string to the value of the received string. If the alarm occurs on a port that has been operating with no alarms, the circuit path has changed or someone entered a new incorrect value into the Current Transmit String field. Complete the following procedure to clear either instance.
TIM-P also occurs on a port that has previously been operating without alarms if someone switches or removes the DS-3 cables or optical fibers that connect the ports. TIM-P is usually accompanied by other alarms, such as an LOS (OC-N) alarm (see page 2-83), an UNEQ-P alarm (see page 2-121), or a PLM-P alarm (see page 2-94). If these alarms accompany TIM-P, reattach or replace the original cables/fibers to clear the alarms.
Procedure: Clear the TIM-P Alarm
Step 1 Log into the circuit source node and click the Circuits tab.
Step 2 Select the circuit reporting the alarm, then click Edit.
Step 3 In the Edit Circuit window, check the Show Detailed Map check box.
Step 4 On the detailed circuit map, right-click the source circuit port and choose Edit J1 Path Trace from the shortcut menu.
Step 5 On the detailed circuit map, right-click the drop/destination circuit port and choose Edit Path Trace from the shortcut menu.
Step 6 Compare the Current Transmit String and the Current Expected String entries in the Edit J1 Path Trace dialog box.
Step 7 If the strings differ, correct the Transmit or Expected strings and click Apply.
Step 8 Click Close.
Step 9 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.183 TPTFAIL (G-Series)
•Major (MJ), Service Affecting (SA)
The Transport (TPT) Layer Failure alarm for the G-series Ethernet (traffic) cards indicates a break in the end-to-end Ethernet link integrity feature of the G1000-2 cards. TPTFAIL indicates a far-end condition and not a problem with the port reporting TPTFAIL.
The TPTFAIL alarm indicates a problem on either the SONET path or the remote Ethernet port that prevents the complete end-to-end Ethernet path from working. If any SONET path alarms such as an AIS-P condition (see page 2-16), an LOP-P alarm (see page 2-79), a PDI-P alarm (see page 2-92), or an UNEQ-P alarm (see page 2-121) exist on the SONET path used by the Ethernet port, the affected port causes a TPTFAIL alarm. Also, if the far-end G1000-2 Ethernet port is administratively disabled or it is reporting a CARLOSS (G Series) alarm (see page 2-33), the C2 byte in the SONET path overhead indicates a PDI-P alarm (see page 2-92) which in turn causes a TPTFAIL to be reported against the near-end port.
When a TPTFAIL alarm occurs, the near-end port is automatically disabled (transmit laser turned off). In turn the laser shutoff can also cause the external Ethernet device attached at the near end to detect a link down and turn off its transmitter. This also causes a CARLOSS condition to occur on the reporting port. In all cases the source problem is either in the SONET path being used by the G1000-2 port or the far- end G1000-2 port to which it is mapped.
Procedure: Clear the TPTFAIL (G-Series) Alarm
Step 1 An occurrence of TPTFAIL on a G1000-2 port indicates either a problem with the SONET path that the port is using or with the far-end G1000-2 port that is mapped to the port. Clear any alarms being reported by the OC-N card on the G1000-2 circuit.
Step 2 If no alarms are reported by the OC-N card, or if a PDI-P alarm (see page 2-92) is reported, the problem might be on the far-end G1000-2 port. Clear any alarms, such as CARLOSS, reported against the far-end port or card.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.184 TRMT
•Major (MJ), Service Affecting (SA)
A Missing Transmitter (TRMT) alarm occurs when there is a transmit failure on the XTC-14 card because of an internal hardware failure. The card must be replaced.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the TRMT Alarm
Step 1 Complete the "Physically Replace a Card" procedure for the reporting XTC-14 card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 2 If the alarm does not clear, call the Technical Assistance Center (TAC) at (1-800-553-2447) to discuss the failed card and possibly open a returned materials authorization (RMA).
2.6.185 TRMT-MISS
•Major (MJ), Service Affecting (SA)
A Facility Termination Equipment Transmitter Missing (TRMT-MISS) alarm occurs when the facility termination equipment detects an incorrect amount of impedance on its connector. Incorrect impedance is detected when a transmit cable is missing on the XTC-14 does not match the inserted card; for example, an SMB connector or a BNC connector connects to an XTC-14 card instead of an XTC-28-3 card.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Note DS-1s are four-wire circuits and need a positive and negative connection for both transmit and receive.
Procedure: Clear the TRMT-MISS Alarm
Step 1 Verify that the device attached to the XTC-14 port is operational.
Step 2 If the device is operational, verify that the cabling is securely connected.
Step 3 If the cabling is secure, verify that the pinouts are correct.
Step 4 If the pinouts are correct, replace the transmit cable.
Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.186 UNEQ-P
•Critical (CR), Service Affecting (SA)
An SLMF UNEQ Path alarm occurs when the path does not have a valid sender. The UNEQ-P indicator is carried in the C2 signal path byte in the SONET overhead. The source of the problem is the node that is transmitting the signal into the node reporting the UNEQ-P.
The alarm might result from an incomplete circuit or an empty VT tunnel. UNEQ-P occurs in the node that terminates a path.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Deleting a circuit affects traffic.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Note If you have created a new circuit but it has no signal, an UNEQ-P alarm is reported on the OC-N cards and an AIS-P condition (see page 2-16) is reported on the terminating cards. These alarms clear when the circuit carries a signal.
Procedure: Clear the UNEQ-P Alarm
Step 1 In node view, click View > Go to Network View.
Step 2 Right-click the alarm to display the Select Affected Circuits dialog box.
Step 3 Click the Select Affected Circuits dialog box.
Step 4 When the affected circuits appear, look in the Type column for VTT, which indicates a VT tunnel circuit. A VT tunnel with no VTs assigned might be the cause of an UNEQ-P alarm.
Step 5 If the Type column does not contain VTT there are no VT tunnels connected with the alarm. Go to Step 7.
Step 6 If the Type column does contain VTT, attempt to delete these row(s). The node view does not allow you to delete a valid VT tunnel or one with a valid VT circuit inside:
a. Click the VT tunnel circuit row to highlight it. Complete the "Delete a Circuit" procedure.
b. If an error message dialog box appears, the VT tunnel is valid and not the cause of the alarm.
c. If any other columns contain VTT, repeat Step 6.
Step 7 If all ONS nodes in the ring appear in the CTC network view, verify or not whether there are incomplete circuits:
a. Click the Circuits tab.
b. Verify that INCOMPLETE is not listed in the State column of any circuits.
Step 8 If you find circuits listed as incomplete, use an optical test set to verify that these circuits are not working circuits that continue to pass traffic.
For specific procedures to use the test set equipment, consult the manufacturer.
Step 9 If the incomplete circuits are not needed or are not passing traffic, delete the incomplete circuits.
Complete the "Delete a Circuit" procedure.
Step 10 Recreate the circuit with the correct circuit size. Refer to the Cisco ONS 15327 Procedure Guide.
Step 11 Log back in and verify that all circuits terminating in the reporting card are active:
a. Click the Circuits tab.
b. Verify that the State column lists all circuits as active.
Step 12 If the alarm does not clear, clean the far-end optical fiber according to site practice. If no site practice exists, complete the procedure in the Cisco ONS 15327 Procedure Guide.
Step 13 If the alarm does not clear, complete the "Physically Replace a Card" procedure for the OC-N/DS-N cards.
Note When replacing a card with an identical type of card, no additional CTC provisioning is required.
Step 14 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.187 UNEQ-V
•Major (MJ), Service Affecting (SA)
An SLMF UNEQ VT alarm indicates that the node is receiving SONET path overhead with bits 5, 6, and 7 of the V5 overhead byte all set to zeroes. The source of the problem is the node that is transmitting the VT-level signal into the node reporting the UNEQ-P. The problem node is the next node upstream that processes the signal at the VT level. The V in UNEQ-V indicates that the failure has occurred at the VT layer.
Warning Invisible laser radiation might be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam directly with optical instruments. Viewing the laser output with certain optical instruments (for example, eye loupes, magnifiers, and microscopes) within a distance of 100 mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327. Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the UNEQ-V Alarm
Step 1 Complete the "Clear the UNEQ-P Alarm" procedure.
Step 2 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.188 WKSWPR
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Working Switched To Protection (WKSWPR) condition occurs when a line experiences an LOS (OC-N) alarm (see page 2-83), an SF condition (see page 2-106), or an SD condition (see page 2-104).
Procedure: Clear the WKSWPR Condition
Step 1 Complete the "Clear the LOF (OC-N) Alarm" procedure.
Step 2 If the condition does not clear, log onto http://www.cisco.com/tac for more information or call TAC to report a service-affecting problem (1-800-553-2447).
2.6.189 WTR
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Wait To Restore (WTR) condition occurs when a WKSWPR condition (see page 2-124) is raised the wait-to-restore time has not expired, meaning the active protect path cannot revert to the working path. The condition clears when the timer expires and traffic is switched back to the working path.
Note WTR is an informational condition. It does not require troubleshooting.
2.7 XTC Line Alarms
The XTC-28-3 card provides three choices of line types: ESF, D4, or Unframed. The choice of framing format determines the line alarms that the XTC-28-3 card reports. The following table lists the line alarms reported under each format.
The choice of framing format does not affect the reporting of STS alarms. Regardless of format, the XTC-14 card reports the same STS alarms as the standard XTC-28-3 card does.
