Alarm Troubleshooting
This chapter gives CiscoONS15600SDH alarm and condition default severities, descriptions, and when necessary, troubleshooting procedures. Table2-1 gives an alphabetical list of alarms and conditions that appear on the ONS15600SDH. Table2-2 gives a list of alarms and conditions organized by type. Both lists cross-reference the alarm and condition entries. The entries contain more detailed descriptions and troubleshooting information.
Alarm troubleshooting procedures apply to the Cisco Transport Controller (CTC) version of the alarm. If a troubleshooting procedure does not clear the alarm, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information.
Active card alarms have these default severities as defined in ITU-T G.783:
•
Critical (CR)
•Major (MJ)
•Minor (MN)
Standby card alarms have a default severity of minor, Non-Service Affecting (MN, NSA) as defined in ITU-T G.783.
Conditions are commonly encountered while troubleshooting alarms. In this chapter, they have these default severity ratings:
•Not alarmed, Non-Service Affecting (NA, NSA)
•Not reported, Non-Service Affecting (NR, NSA)
Note For a comprehensive list of all conditions, refer to the CiscoONS15600SDHTL1Test Access .

2.3 Trouble Notifications
The ONS15600SDH uses standard ITU categories to characterize levels of trouble. The ONS15600SDH reports alarmed trouble notifications in the Alarms window and not alarmed (NA) trouble notifications in the Conditions window in CTC. Alarms signify a problem that the user needs to fix, such as a Loss of Signal ( LOS). Conditions notify the user of an event that does not require action, such as a Switch to a Secondary Timing Reference ( SWTOSEC) or a user-initiated Manual Reset ( MANRESET).
The ITU 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, an LOS is characterized as an SA failure. LOS occurs when the incoming signal or outgoing signal ceases to be detected because of equipment failure or configuration problems. This affects a provided service, because traffic switches to the protect card. The Equipment High Temperature ( EQPT-HITEMP) alarm, which means the ONS15600SDH is hotter than 122 degrees Fahrenheit (50 degrees Celsius), is also an SA failure. Even if a particular port on the card might not be affected, the high temperature affects the network service.
2.3.1 Conditions
When an SA failure is detected, the ONS15600SDH also sends an Alarm Indication Signal (AIS) downstream. When it receives the AIS, the receiving node sends a Remote Defect Indication (RDI) upstream. AIS and RDI belong in the conditions category and show up in the Conditions window of the ONS15600SDH. However, unlike most conditions which are not alarmed, Telcordia classifies these conditions as not reported (NR).
Both CTC and TL1 report NR and NA events as conditions. NA events are also reported as autonomous events under TL1 and in the History window of CTC. For a comprehensive list of conditions, refer to the CiscoONS15600SDH TL1 Command Guide.
2.3.2 Severities
The ONS15600SDH uses ITU-standard severities:
•Critical indicates a severe, service-affecting alarm that needs immediate correction. An example of a critical alarm is BKUPMEMP. This alarm must be resolved immediately to reinstate traffic.
•Major is a serious alarm, but the failure has less of an impact on the network. An example of a major alarm is APSCM. This alarm affects traffic but does not completely shut it down. It has to be resolved quickly.
•Minor alarms do not seriously affect service. An example of a minor alarm is Fast-Start Synchronization ( FSTSYNC). FSTSYNC lets you know that the ONS15600SDH is choosing a new timing reference because the old reference failed. The loss of the prior timing source is something a user needs to check, but it should not immediately disrupt service.
A user can customize ONS15600SDH alarm severities with the alarm profiles feature. For alarm profile procedures, refer to the CiscoONS15600SDH Procedure Guide. This chapter lists the default alarm severity for the active reporting card or port, if applicable.
2.4 Safety Summary
This section covers safety considerations to ensure safe operation of the ONS15600SDH system. Personnel should not perform any procedures in this manual 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:
Caution Hazardous voltage or energy might be present on the backplane when the system is operating. Use caution when removing or installing cards.
Some troubleshooting procedures require installation or removal of optical cards. In these instances, users should pay close attention to the following warnings:
Warning Invisible laser radiation may 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 100mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Warning Class 1 laser product.
2.5 Alarm Procedures
This section lists alarms alphabetically and includes some conditions commonly encountered when troubleshooting alarms. The severities, descriptions, and troubleshooting procedures accompany the alarms and conditions.
2.5.1 AIR-FLOW
•Minor (MN), Non-Service Affecting (NSA)
The shelf Air Flow Degrade alarm accompanies a degradation in air flow to a Core Cross Connect (CXC) card, Timing and Shelf Controller (TSC) card, or an optical (STM-N) card.
Clear the AIR-FLOW Condition
Step 1 Ensure that filler modules are installed in the ONS15600SDH empty slots. Filler modules help airflow.
Step 2 If the alarm does not clear, check the condition of the air filter to determine whether it needs replacement. Complete the "Replace the Air Filter" procedure on page3-10 as necessary.
Step 3 If the alarm does not clear and the filter is clean, remove and reinsert each fan tray (one at a time).
When you reinsert the fan trays, making sure the plugs connect to the backplane receptacles of the ONS 15600 SDH.
Note Fans should run immediately when correctly inserted.
Step 4 If a fan does not run or the alarm persists, complete the "Replace a Fan Tray" procedure on page3-11.
Step 5 If a replacement fan tray does not operate correctly, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information or to report a service-affecting problem.
2.5.2 AIS (BITS)
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Alarm Indication Signal (AIS) BITS condition indicates a problem in the building integrated timing supply (BITS) electrical signal.
Clear the AIS Condition
Step 1 Check upstream BITS equipment for alarms, especially antenna outage, and clear those alarms.
Step 2 If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.3 APSB
•Minor (MN), Non-Service Affecting (NSA)
The Automatic Protection Switching (APS) Byte Failure alarm occurs for traffic (STM-N) cards when line-terminating equipment detects protection-switching byte failure in the incoming automatic protection switching signal. A failure occurs when an inconsistent APS byte or invalid code is detected. Some older non-Cisco SDH nodes send invalid APS codes when they are configured in a 1+1 group with newer SDH nodes such as the ONS15600SDH. These invalid codes raise an APSB on an ONS node. The alarm applies to 1+1 protection groups.
Note APS switches are hitless in the ONS15600SDH.
Clear the APSB Alarm
Step 1 Examine the incoming SDH overhead with an optical test to confirm inconsistent or invalid K bytes. Refer to the CiscoONS15600SDH Procedure Guide for instructions.
Step 2 If corrupted K bytes are confirmed and the upstream equipment is functioning properly, the upstream equipment might not interoperate effectively with the ONS15600SDH. For ONS15600SDH protection switching to operate properly, the upstream equipment might need to be replaced.
Step 3 If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.4 APSCDFLTK
•Minor (MN), Non-Service Affecting (NSA)
The APS Default K Byte Received alarm occurs when a multiplex section-shared protection ring (MS-SPRing) is not properly configured, for example, when a four-node MS-SPRing has one node configured as a subnetwork connection protection (SNCP) ring. A node in an SNCP or 1+1 configuration does not send the two valid K1/K2 APS bytes anticipated by a node configured for MS-SPRing. One of the bytes sent is considered invalid by the MS-SPRing configuration. The K1/K2 byte is monitored by receiving equipment for link-recovery information.
Troubleshooting for APSCDFLTK is often similar to troubleshooting for the "MSSP-OOSYNC" alarm on page2-64.
Clear the APSCDFLTK Alarm
Step 1 Complete the "2.6.1Identify a Ring ID or Node ID Number" procedure to verify that each node has a unique node ID number.
Step2 Repeat Step 1 for all nodes in the ring.
Step 3 If two nodes have the same node ID number, complete the "2.6.4Change 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 that the east port and west port optical fibers are configured correctly. (See the "E-W-MISMATCH" alarm on page2-31.) West port fibers must connect to east port fibers, and vice versa. The CiscoONS15600SDH Procedure Guide provides a procedure for fibering MS-SPRings.
Step 5 If the alarm does not clear, complete the "2.6.11Verify Node Visibility for Other Nodes" procedure.
Step 6 If nodes are not visible, complete the "2.6.12Verify or Create Node DCC Terminations" procedure to ensure that SDH DCC terminations exist on each node.
Step 7 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.5 APSC-IMP
•Minor (MN), Non-Service Affecting (NSA)
An Improper APS Code alarm indicates invalid K bytes. The APSC-IMP alarm occurs on STM-N cards in an MS-SPRing 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.
Caution Always use the supplied ESD wristband when working with a powered ONS15600SDH. Plug the wristband cable into an ESD jack.
Clear the APSC-IMP Alarm
Step1 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 15600 SDH. Troubleshoot the upstream equipment using the procedures in this chapter, as applicable. If the upstream nodes are not ONS 15600 SDHs, 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 "2.6.1Identify 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 using the "2.6.2Change a Ring ID Number" procedure.
Step 5 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.6 APSCINCON
•Minor (MN), Non-Service Affecting (NSA)
An APS Inconsistent alarm accompanies an inconsistent APS byte. The SDH overhead contains K1/K2 APS bytes that notify receiving equipment, such as the ONS15600SDH, to switch the SDH 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.
Clear the APSCINCON Alarm
Step1 Look for other alarms, especially the "LOS" alarm on page2-54, the "LOF" alarm on page2-52, or the "MS-AIS" condition on page2-62. Clearing these alarms clears the APSCINCON alarm.
Step 2 If an APSINCON alarm occurs without other alarms, log onto http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.7 APSCM
•Major (MJ), Service Affecting (SA)
The APS-Channel Mismatch Failure alarm occurs on traffic (STM-N) cards when the received K2 channel ID does not match the transmitted K1 channel ID. 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 only occurs on 1+1 protection groups.
Warning Invisible laser radiation may 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 100mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Caution Always use the supplied ESD wristband when working with a powered ONS15600SDH. Plug the wristband cable into the ESD jack located on the lower-left side of the shelf assembly.
Note APS switches are hitless in the ONS15600SDH.
Clear the APSCM Alarm
Step 1 Verify that the working port fibers connect directly to the adjoining node's working port fibers.
Step 2 If the alarm does not clear, verify that the protection port fibers connect directly to the adjoining node's protection port fibers.
Step 3 If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.8 APSCNMIS
•Major (MJ), Service Affecting (SA)
The APS Node ID Mismatch 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 can occur and clear when an MS-SPRing 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.
Clear the APSCNMIS Alarm
Step 1 Complete the "2.6.1Identify 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:
a. Record the repeated node ID.
b. Click Close in the Ring Map dialog box.
c. Complete the "2.6.4 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 > MS-SPRing tabs. The MS-SPRing window shows the node ID of the login node.
Step 3 If the alarm does not clear, use the "2.6.13Lock Out an MS-SPRing Span" procedure, then complete the "2.6.14Clear an MS-SPRing Span Lockout" procedure to clear the lockout. Applying and removing a lockout on a span causes the ONS15600SDH to generate a new K byte. The APSCNMIS alarm clears when the node receives a K byte containing the correct node ID.
Step 4 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.9 AU-AIS
•Not Reported (NR), Non-Service Affecting (NSA)
An Administration Unit (AU) AIS condition applies to the administration unit, which consists of the VC capacity and pointer bytes (H1, H2, and H3) in the SDH frame.
Generally, any AIS is a special SDH signal that tells the receiving node that the sending node has no valid signal available to send. AIS is not considered an error. The fault condition AIS is raised by the receiving node on each input where it sees the signal AIS instead of a real signal. In most cases when this condition is raised, an upstream node is raising an alarm to indicate a signal failure; all nodes downstream from it only raise some type of AIS. This condition clears when you resolved the problem on the upstream node.
Clear the AU-AIS Condition
Step 1 Complete the "Clear the AIS Condition" procedure.
Step 2 If the condition does not clear, complete the "Clear the APSB Alarm" procedure.
Step 3 If the condition does not clear, log into http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.10 AU-LOP
•Critical (CR), Service Affecting (SA)
An Administration Unit Loss of Pointer Path alarm indicates that the transmitted optical circuit size is different from the provisioned optical circuit size. AU-LOP occurs when valid H1/H2 pointer bytes are missing from the SDH overhead. Receiving equipment monitors the H1/H2 pointer bytes to locate the SDH payload. An AU-LOP alarm means that eight, nine, or ten consecutive frames do not have valid pointer values. The alarm clears when three consecutive valid pointers are received.
One of the conditions that can cause this alarm is a transmitted VC4-Nc circuit that is different from the provisioned VC4-Nc. This condition causes a mismatch of the path type on the concatenation facility. It occurs when there are eight to ten new data flags received, or eight to ten invalid pointers. For example, if a VC4-4c or VC4 is sent across a path provisioned for VC4-16c, a LOP alarm occurs.
Caution Always use the supplied ESD wristband when working with a powered ONS15600SDH. Plug the wristband cable into the ESD jack located on the lower-left outside edge of the shelf assembly.
Clear the AU-LOP Alarm
Step 1 Complete the "Switch all SNCP Circuits on a Span" procedure on page3-4 or the "Initiate a Force Switch on a 1+1 Port" procedure on page3-4 as appropriate.
Step 2 Use a test set to verify that the incoming signal is valid; refer to the CiscoONS15600SDH Procedure Guide for instructions on testing optical circuits. If the upstream signal is not valid, troubleshoot upstream.
Step 3 If the incoming signal is valid, complete the "2.6.15Remove and Replace a Card" procedure for the reporting card.
Note If the traffic (STM-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port using the "Bridge and Roll Traffic" procedure in the CiscoONS15600SDH Procedure Guide. Label the bad port, and place it out of service until the card can be replaced.
Step 4 If the alarm does not clear, log on to http://www.cisco.com/tac for more informationor log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information or to report a service affecting problem.
2.5.11 AUD-LOG-LOSS
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Audit Trail Log Loss condition occurs when the log is 100 percent full and the oldest entries are being replaced as new entries are generated. The log capacity is 640 entries.
Clear the AUD-LOG-LOSS Condition
Step 1 In node view, click the Maintenance > Audit tabs.
Step 2 Click Retrieve and click Archive .
Step 3 In the Archive Audit Trail dialog box, navigate to the directory (local or network) where you want to save the file.
Step4 Enter a name in the File Name field.
You do not have to assign an extension to the file. It is readable in any application that supports text files, such as WordPad, Microsoft Word (imported), etc.
Step 5 Click Save .
The 640 entries will be saved in this file. New entries will continue with the next number in the sequence, rather than starting over.
Note When you have archived a group of audit trail entries, they are no longer visible in CTC. The entries cannot be imported into CTC.
Step 6 If the alarm does not clear, log onto http://www.cisco.com/tac for more information log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of TAC toll-free numbers for your country.
2.5.12 AUD-LOG-LOW
•Not Reported (NR), Non-Service Affecting (NSA)
The Audit Trail Log Loss condition occurs when the audit trail log is 80 percent full. The log capacity is 640 entries.
Note AUD-LOG-LOW is an informational condition. It does not require troubleshooting.
2.5.13 AUTORESET
•Minor (MN), Non-Service Affecting (NSA)
The Automatic System Reset alarm occurs when a TSC card, CXC card, or traffic (STM-N) card automatically reboots. The reboot is caused by changing an IP address or performing any other operation that causes the active TSC card to lose communication with the card (a "heartbeat" failure). The TSC card automatically resets the card it loses communication with. If communication is not reestablished, the card resets again.
Note If an optical card associated with an active port in a 1+1 protection group resets, all DCC traffic terminated or tunneled on the active port is lost while the card resets. No DCC traffic is lost during a reset of an optical card associated with a standby port.
If the lack of communication continues, the AUTORESET alarm is cleared and the EQPTBOOT alarm occurs. Consequently, AUTORESET does not need troubleshooting.
2.5.14 AUTOSW-AIS-SNCP
•Not Reported (NR), Non-Service Affecting (NSA)
The Automatic Protection Switch AIS condition indicates that automatic SNCP path protection switching occurred because of the "AU-AIS" condition on page2-14 on the circuit path.
Troubleshoot with the "Clear the AU-AIS Condition" procedure . If the alarm does not clear, log into http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country in order to report a service-affecting problem.
2.5.15 AUTOSW-LOP-SNCP
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Automatic Protection Switch Loss of Path (LOP) condition indicates that automatic SNCP path protection switching occurred because of the "AU-LOP" condition on page2-14 on the VC4 signal.

2.5.40 E-W-MISMATCH
•Major (MJ), Service-Affecting (SA)
A Procedural Error Misconnect East/West Direction 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.
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 2 is west and Slot 12 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.
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 the node view, from the View menu choose GotoNetworkView .
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-
Node2/Slot2/Port1 (2F MS-SPRing STM16, Ring ID=0), label the end of the span that connects Node1 and Node 2 at the Node 1 end as Slot 12/Port 1. Label the Node 2 end of that same span Slot 2/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.
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 100mm might pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified might result in hazardous radiation exposure.

Step 7 If fiber continuity to the ports is OK, verify that the correct port is in service:
a. Confirm that the STM-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 STM-N port is in service, double-click the card in CTC to open the card view.
c. Click the Provisioning > Line tabs.
d. Verify that the State column lists the port as IS.
e. If the State column lists the port as OOS, click the column and choose IS . Click Apply .
Step 8 If the correct port is 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.
Caution Using an optical test set disrupts service on the optical (traffic) card. It might be necessary to manually switch traffic carrying circuits over to a protection path.
Step 9 If the signal is valid, clean the fiber according to site practice. If no site practice exists, use the procedure in the CiscoONS15600SDH Procedure Guide.
Step 10 If cleaning the fiber does not clear the condition, verify that the power level of the optical signal is within the STM-N card's receiver specifications. The "Optical Traffic Card Transmit and Receive Levels" section on page1-32 lists these specifications.
Step 11 Repeat Steps 6 through 10 for any other ports on the card.
Step 12 If the optical power level for all STM-N cards is within specifications, complete the "Replace an STM-16 Card or STM-64 Card" procedure on page3-2 for the protect standby STM-N card.

2.5.55 FREQ-MISMATCH
•Minor (MN), Non-Service Affecting (NSA)
The Frequency Mismatch alarm occurs when one of the two TSC cards has a timing module failure that causes an inconsistency between the TSC card timing frequencies. This alarm can be caused by the active or standby TSC card.
The ONS15600SDH checks timing frequency synchronization in 83-minute cycles. The FREQ-MISMATCH alarm occurs if two consecutive timing check cycles show frequency mismatches. The alarm is cleared if one cycle shows a timing frequency match between the TSC cards.
Clear the FREQ-MISMATCH Alarm
Step 1 Complete the "2.6.15Remove and Replace a Card" procedure for the standby TSC card.
Step 2 Wait for two intervals of 83 minutes (2 hours and 46 minutes) and check the node view Alarms window to see if the alarm is cleared.
During the initial 83-minute synchronization check cycle when the replacement standby TSC card is booting up, the replacement TSC card is attaining the timing from the BITS or internal source, so it is normal that the two TSC cards are not synchronized. The ONS 15600 SDH system disregards the result of this check cycle and begins keeping track of synchronization in the second 83-minute cycle. If the result of the cycle shows that the TSC cards are synchronized properly, the alarm is cleared.
Step 3 If the FREQ-MISMATCH alarm did not clear after two timing check cycles, it means that the second timing cycle resulted in a mismatch. Wait a third 83-minute cycle (1 hour and 23 minutes) and check the alarm again.
If the alarm has cleared, it means the third cycle showed that the TSC card timing modules were synchronized. If the alarm remains, it means that the ONS 15600 SDH system has had two frequency mismatch cycles, and indicates a problem with the other TSC card.
Step 4 If the FREQ-MISMATCH alarm remains after three 83-minute cycles, complete the "2.6.7Soft-Reset the TSC Card Using CTC" procedure to make the TSC card standby.
Step 5 Complete the "2.6.15Remove and Replace a Card" procedure for the standby TSC card.
The card removal and reboot temporarily clears the alarm.
Step 6 Wait for three intervals of 83 minutes (4 hours and 9 minutes) and check CTC to see if the FREQ-MISMATCH alarm has recurred. If it has not recurred, the problem is solved.
Step 7 If the alarm has recurred after both TSC cards have been replaced, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.56 FRNGSYNC
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Free-Running Synchronization Mode condition occurs when the reporting node is in free-run synchronization mode. External timing sources have been disabled and the node is using its internal clock, or the ONS15600SDH has lost its designated BITS timing source.
Clear the FRNGSYNC Condition
Step 1 Check for additional alarms that relate to timing and troubleshoot as necessary.
Step 2 Reestablish a primary and secondary timing source according to local site practice. Refer to the CiscoONS15600SDH Procedure Guide for instructions.
Step 3 If the condition does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.57 FSTSYNC
•Not Alarmed (NA), Non-Service Affecting (NSA)
The Fast Synchronization condition occurs when the ONS15600SDH synchronizes its clock modules. Since the ONS15600SDH uses Stratum 3E timing, synchronization can take about 12 minutes. This condition occurs on the TSC card where the timing distribution is sourced. Whenever this condition is active, any timing or controller switching can affect the traffic. Errorless switching is not guaranteed. The "UNPROT-SYNCCLK" alarm on page2-83 can accompany this condition if there is no timing protection is available while the clock is synchronizing.

2.5.59 HELLO
•Minor (MN), Non-Service Affecting (NSA)
The Open Shortest Path First (OSPF) Hello Fail alarm occurs when SDH DCC termination OSPF area IDs are mismatched between two DCC terminations for a span. On a span between two ONS15600SDHs, this alarm occurs at both nodes containing the mismatched DCC area IDs. On a span between an ONS15600SDH and an ONS 15600, this alarm is raised only on the ONS15600SDH node because the ONS 15600 does not currently support this alarm. Mismatched OSPF area IDs can cause CTC to lose management across the link.
Clear the HELLO Alarm
Step 1 Log into both end nodes with the DCC terminations.
Step 2 On the nodes where the alarm occurred, record the slot and port (from the Slot column and Port column in the Alarms window) that the Hello alarm occurs against. This information helps you determine which DCC termination is mismatched.
Tip You can log into another node by going to network view and double-clicking the node.
Step 3 On one node, in node view, click the Provisioning > Network > OSPF tabs.
Step 4 In the DCC/GCC OSPF Area ID Table area, locate the alarmed DCC termination by comparing slot and port numbers to the slot and port number indicated in the alarm on the node.
Step 5 Click the Area ID column cell for the mismatched DCC termination.
Step 6 Change the area ID in the cell to the same ID as its partner DCC termination. (ONS 15454 SDH, ONS 15600, and ONS15600SDH default to 0.0.0.0 format addresses.)

2.5.60 HLDOVRSYNC
•Not Alarmed (NA), Non-Service Affecting (NSA) condition
The Holdover Synchronization Mode condition is caused by loss of the primary and second timing references in the node. Timing reference loss occurs when line coding on the timing input is different from the configuration on the ONS15600SDH. It also usually occurs during the selection of a new node reference clock. This alarm indicates that the ONS15600SDH has gone into holdover and is using the ONS15600SDH G.813 internal reference clock. The condition clears when primary or second timing is reestablished. After the 24-hour holdover period expires, timing slips might begin to occur on an ONS15600SDH relying on an internal clock.
Troubleshoot with the "Clear the FRNGSYNC Condition" procedure . If the condition does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.

2.5.63 HP-RDI
•Not Reported (NR), Non-Service Affecting (NSA)
A High Order Path-Remote Fault Indication condition occurs when the ONS15600SDH detects an RFI in the SDH overhead of the VC4 signal because of a fault in another node. Resolving the fault in the adjoining node clears the HP-RDI alarm in the reporting node.
HP-RDI occurs in the node that terminates a path. The path layer is the segment between the originating equipment and the terminating equipment. This segment can encompass several consecutive line segments. An HP-RDI error message on theONS15600SDH indicates that the node reporting the HP-RDI is the terminating node on that path segment.
Clear the HP-RDI Condition
Step 1 Verify that the ports are enabled and in-service on the reporting ONS15600SDH.
In the card-level view, traffic port state is indicated by the color of the port:
•Gray—Out of service (OOS)
•Green—In service (IS)
•Red—Critical alarm
•Yellow—Minor alarm
•Orange—Major alarm
Step 2 If a port is OOS, click the Provisioning > MS tabs and choose In Service from the drop-down menu for that port. Click Apply .
Step 3 To find the path and node failure, verify the integrity of the SDH circuit path at each of the intermediate SDH nodes, checking for inconsistencies in path size or protection configuration.
Step 4 Identify and resolve alarms in reporting node. The "UNEQ-P" alarm on page2-82 frequently needs to be resolved. Complete the "Clear the UNEQ-P Alarm" procedure.

2.5.80 LPBKCRS
•Not Alarmed (NA), Service Affecting (SA)
The Loopback Cross-Connect condition indicates a software cross-connect loopback is active between a traffic (STM-N) card and a cross-connect card.
Loopback is a commonly used troubleshooting technique. A signal is sent out on a link or section of the network and returned to the sending device. If the signal does not return or returns with errors, the test confirms that the problem is present in the tested link. By setting up loopbacks on various parts of the node and excluding other parts, you can logically isolate the source of the problem. For more information on loopbacks, see the "Identify Points of Failure on a Circuit Path" procedure on page1-2.
Three types of loopbacks are available: Cross-Connect, Facility, and Payload. Cross-connect loopbacks troubleshoot STM-16 signals on CXC cards. Facility loopbacks troubleshoot STM-16 ports only and are generally performed locally or at the near end. Payload loopbacks troubleshoot STM-64 ports only and are generally performed locally or at the near end.
Clear the LBKCRS Condition

2.5.91 MEA
•Critical (CR), Service Affecting (SA)
The Mismatch Between Equipment Type and Provisioned Attributes alarm is reported against a card slot when the physical TSC card, CXC card, STM-16, or STM-64 card in a slot does not match the card type provisioned for that slot in CTC. Deleting the incompatible card in CTC or physically removing the card clears the alarm.
Clear the MEA Alarm
Step 1 Physically verify the type of card that sits in the slot reporting the MEA alarm.
Step 2 In CTC, click the node view Inventory tab to reveal the provisioned card type.
Step 3 If you prefer the card type depicted by CTC, complete the "2.6.15Remove and Replace a Card" procedure for the reporting card and replace it with the card type depicted by CTC (provisioned for that slot).
Note CTC does not allow you to delete a card if at least one port on the card is in service, has a path mapped to it, is paired in a working-protection scheme, has DCC enabled, or is used as a timing reference.
Step 4 If you want to leave the installed card in the slot but it is not in service, delete any circuits mapped to it by following the "Clear the IMPROPRMVL Alarm" procedure.
Step 5 Place the cursor over the provisioned card in CTC and right-click to choose Delete Card .
When the card is deleted in CTC, the card that physically occupies the slot automatically reboots and appears in CTC.
Step 6 If the alarm does not clear, log on to http://www.cisco.com/tac for more information or or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information or to report a service-affecting problem.
2.5.92 MFGMEM (CAP)
•Minor (MN), Non-Service Affecting (NSA)
The Manufacturing Data Memory Failure CAP alarm occurs if the ONS15600SDH cannot access the data in the EEPROM on the CAP. MFGMEM is caused by EEPROM failure on the CAP, fuse failure for the EEPROM, or TSC card inability to read the MAC address from the CAP.
The EEPROM stores manufacturing data, including the MAC address, that is needed for compatibility and inventory issues. If the TSC card cannot read a valid MAC address, this disrupts IP connectivity and turns the ONS15600SDH icon in the CTC network view gray. If the alarm is accompanied by the "PWR-FA" alarm on page2-68 , the 5-VDC fuse for the EEPROM might be tripped. If that is the case, use the procedure below to eliminate the TSC card as the cause of the alarm, but do not attempt to troubleshoot it further. Log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
Tip You can reestablish the node management capability by disconnecting the Ethernet cable from the CAP and connecting it to the active TSC card LAN port.
Clear the MFGMEM Alarm on the CAP by Resetting the TSC Card
Step 1 Complete the "2.6.7Soft-Reset the TSC Card Using CTC" procedure.
Wait for the "FSTSYNC" condition on page 2-42 to clear.
Step 2 If the alarm does not clear, complete the "2.6.8Hard-Reset the TSC Using CTC" procedure.
If the alarm does not clear, log on to http://www.cisco.com/tac f or more information or or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information. The standby TSC card might also need replacement. If the alarm continues after both TSC cards have been replaced, the problem lies in the EEPROM on the CAP, and this must be replaced.
Step 3 When the alarm is cleared, you can make the standby TSC card active again by completing the "2.6.7Soft-Reset the TSC Card Using CTC" procedure.
2.5.93 MFGMEM (CXC, Traffic Card, TSC)
•Minor (MN), Non-Service Affecting (NSA)
The Manufacturing Data Memory Failure (CXC, Traffic Card, TSC) alarm occurs if the ONS15600SDH EEPROM on a CXC, STM-N, or TSC card fails.
Clear the MFGMEM Alarm on the CXC, TSC, or Traffic Card
Step 1 If the alarm is reported against a TSC card, troubleshoot with the "Clear the MFGMEM Alarm on the CAP by Resetting the TSC Card" procedure.
Step 2 If the reporting card is an active traffic line port in a 1+1 group or an SNCP, ensure that an APS traffic switch has occurred to move traffic to the protect port.
•An SNCP APS is identified by an AUTOSW-type alarm or condition (such as AUTOSW-AIS, AUTOSW-LOP-SNCP, AUTOSW-PDI-SNCP, AUTOSW-SDBER-SNCP, AUTOSW-SFBER-SNCP, or AUTOSW-UNEQ-SNCP).
•A 1+1 APS is identified on the node view Maintenance > Protection window. If you click the protection group, in the Selected Group list, the ports are designated as Working/Standby and Protect/Active.
Step 3 If the reporting port is part of an SNCP, complete the "Switch all SNCP Circuits on a Span" procedure on page3-4. If the port is part of a 1+1 group, complete the "Initiate a Force Switch on a 1+1 Port" procedure on page3-4.
Step 4 If the reporting card is a CXC card and an automatic switch to the preferred copy CXC card occurred, traffic automatically switches to the alternate copy.
Step 5 Perform a CTC hard reset on the reporting card (or a soft reset on the CXC card):
Caution Use hard resets with caution. There can be up to 15 other sets of bandwidth affected by a hard reset. A forced hard reset of a CXC card will cause a service disruption.
a. Open the node view.
b. Position the CTC cursor over the card reporting the alarm.
c. Right-click and choose Hard-reset Card (or Soft-reset Card ) from the shortcut menu.
d. Click Yes in the Hard-reset Card (or Soft-reset Card) dialog box.
Step 6 If the CTC reset does not clear the alarm, remove and reinsert (reseat) the card:
a. Open the card ejectors.
b. Slide the card out of the slot.
c. Slide the card into the slot along the guide rails.
d. Close the ejectors.
Step 7 If the physical reseat of the card does not clear the alarm, complete the "2.6.15Remove and Replace a Card" procedure.
Note If the traffic (STM-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port using the "Bridge and Roll Traffic" procedure in the CiscoONS15600SDH Procedure Guide. Label the bad port, and place it out of service until the card can be replaced.
Step 8 If the MFGMEM alarm continues to report after you replaced the card, the problem lies in the EEPROM. Log on to http://www.cisco.com/tac for more information or or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information.
Step 9 If the alarm clears and it was reported by a traffic card, traffic reverts to the working port if an automatic switch occurred. If traffic was manually switched in a 1+1 protection group, revert traffic to the original port by completing the "Clear a Force Switch on a 1+1 Port" procedure on page3-7. If traffic was manually switched in an SNCP, revert traffic to the original path by completing the "Clear a Force Switch on a SNCP Span" procedure on page3-7.
If an automatic switch to the alternate copy CXC card occurred, traffic is automatically restored to the preferred copy.
Step 10 If the reporting card is a TSC card and you want to make the standby TSC card active again, complete the "2.6.7Soft-Reset the TSC Card Using CTC" procedure.
2.5.94 MFGMEM (FAN)
•Critical (CR), Service Affecting (SA)
The Manufacturing Data Memory Fan alarm occurs if the ONS15600SDH EEPROM on a fan tray fails. MFGMEM can be accompanied by the "FAN-FAIL" alarm on page2-36.
Clear the MFGMEM (FAN) Alarm
Step 1 Pull out the fan tray.
Step 2 Reinsert the fan tray, making sure you can hear the fans start operating. Fans should run immediately when correctly inserted.
Step 3 If a fan does not run or the alarm persists, complete the "Replace a Fan Tray" procedure on page3-11.
Step 4 If a replacement fan tray does not operate correctly, log on to http://www.cisco.com/tac for more information or or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information or to report a service-affecting problem.
2.5.95 MS-AIS
•Not Reported (NR), Non-Service Affecting (NSA)
The Multiplex Section AIS condition indicates that there is a defect in the multiplexing section layer of the SDH overhead. The line layer refers to the segment between two SDH devices in the circuit and is also known as a maintenance span. The line layer deals with SDH payload transport, and its functions include multiplexing and synchronization.
Generally, any AIS is a special SDH signal that tells the receiving node that the sending node has no valid signal available to send. AIS is not considered an error. The fault condition AIS is raised by the receiving node on each input where it sees the signal AIS instead of a real signal. In most cases when this condition is raised, an upstream node is raising an alarm to indicate a signal failure; all nodes downstream from it only raise some type of AIS. This condition clears when you resolved the problem on the upstream node.
Note DS-3 facility and terminal loopbacks do not transmit DS-3 MS-AIS in the direction away from the loopback. Instead of DS-3 MS-AIS, a continuance of the signal transmitted to the loopback is provided.
Clear the MS-AIS Condition
Step 1 Complete the "Clear the AIS Condition" procedure.
Step 2 If the condition does not clear, log into http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.96 MS-DEG
•Not Alarmed (NA), Non-Service Affecting (NSA)
A Multiplex Section-Signal Degrade Line condition occurs for an optical port that detects a signal degrade condition. Signal degrade is defined by Telcordia as a "soft failure" condition. MS-DEG and the "MS-EXC" condition on page2-64 monitor the incoming bit error rate (BER) and are similar alarms. SD is triggered at a lower BER than SF. The BER threshold on the ONS15600SDH is user provisionable and has a range for SD from 10-9 to 10-5.
MS-DEG causes a switch from the working card to the protect card at the line (facility) level. A line- or facility-level SD alarm travels on the B2 byte of the SDH overhead. The SD condition clears when the BER level falls to one-tenth of the threshold level that triggered the alarm. A BER increase is sometimes caused by a physical fiber problem, including a faulty or incorrectly plugged fiber connection, a bend in the fiber that exceeds the permitted bend radius, or a bad fiber splice.
Warning Invisible laser radiation may 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 100mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Caution Always use the supplied ESD wristband when working with a powered ONS15600SDH. Plug the wristband cable into the ESD jack located on the lower-left outside edge of the shelf assembly.
Clear the MS-DEG Condition
Step 1 Verify that the user-provisionable BER threshold is set at the expected level:
a. From the node view, double-click the card reporting the alarm to open the card view.
b. Click the Provisioning > MS tabs.
c. Under the SD BER column on the Provisioning window, verify that the cell entry is consistent with what the system was originally provisioned for. The default setting is 1E-7.
d. If the entry is consistent with what the system was originally provisioned for, continue with Step 2 .
e. If the entry is not consistent the original provisioning, click the cell to reveal a drop-down menu of choices and choose the entry consistent with the original provisioning.
f. Click Apply .
Step 2 Ensure that the fiber connector for the card is completely plugged in. For more information about fiber connections and card insertion, refer to the CiscoONS15600SDH Procedure Guide.
Step 3 Use an optical test set to measure the power level of the line to ensure that it is within guidelines. Refer to the CiscoONS15600SDH Procedure Guide for circuit test procedures.
Step 4 Verify that optical receive levels are within the acceptable range.
Step 5 Clean the fiber connectors at both ends:
a. Clean the fiber connectors according to local site practice.
b. If no local practice exists, use a Cletop Real-Type, 3M OGI connector cleaner, or equivalent fiber-optic cleaner and follow the instructions accompanying the product and/or consult the procedures in the Cisco ONS 15600 SDH Procedure Guide.
Step 6 Clean the optical transmitter and receiver by following site practice.
Step 7 Verify that a single-mode laser is used at the far end.
Step 8 If the problem persists, complete the "2.6.15Remove and Replace a Card" procedure on the transmitter card at the other end of the optical line.
Note If the traffic card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port using the "Bridge and Roll Traffic" procedure in the CiscoONS15600SDH Procedure Guide. Label the bad port, and place it out of service until the card can be replaced.
2.5.97 MS-EXC
•Not Alarmed (NA), Non-Service Affecting (NSA)
A Multiple Section-Signal Fail condition occurs when the quality of the signal on STM-16 and STM-64 cards causes the BER on the incoming optical line to exceed the SF threshold. Signal failure is defined by Telcordia as a "hard failure" condition. MS-DEG and MS-EXC both monitor the incoming BER error rate and are similar alarms, but SF is triggered at a higher BER than SD. The default value of NA is determined by TelcordiaGR-253-CORE. The BER threshold on the ONS15600SDH is user provisionable and has a range for SF from 10-5 to 10-3.
MS-EXC causes a switch from the working port to the protect port at the line (facility) level. A line or facility level SF alarm travels on the B2 byte of the SDH overhead. The SF alarm clears when the BER level falls to one-tenth of the threshold level that triggered the alarm. 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. Troubleshoot with the "Clear the MS-DEG Condition" procedure.
2.5.98 MS-RDI
•Minor (MN), Minor (MN)
The Multiplex Section (MS) Remote Defect Indication (RDI) condition indicates that there is an RDI occurring at the SDH overhead multiplexing section level.
An RDI occurs when the ONS 15600 SDH detects an RDI in the SDH overhead because of a fault in another node. Resolving the fault in the adjoining node clears the MS-RDI condition in the reporting node.
Clear the MS-RDI Condition
Step 1 Log into the far-end node of the reporting ONS 15600 SDH.
Step 2 Verify whether there are other alarms, especially the "2.5.79LOS" procedure.
Step 3 Clear the main alarm. Refer to the appropriate alarm section in this chapter for the procedure.
Step 4 If the condition does not clear, log into http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco TAC toll-free numbers for your country.
2.5.99 MSSP-OOSYNC
•Major (MJ), Service-Affecting (SA)
The MS-SPRing Out Of Synchronization alarm occurs when a node on a working ring loses its DCC connection. CTC cannot generate the ring table and raises the MSSPR-OSYNC alarm.
Clear the MSSP-OOSYNC Alarm
Step 1 Verify cabling continuity to the node reporting the alarm.
When the DCC is established between the node and the MS-SPRing, it becomes visible to the MS-SPRing and should be able to function on the circuits.
Step 2 If alarms occur when you provisioned the DCCs, see the "EOC" alarm on page2-28.
Step 3 If the alarm does not clear, log onto http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.100 OPEN-SLOT
•Major (MJ), Non-Service Affecting (NSA)
One of the input/output (I/O) slots (Slots 1 through 4 and 11 through 14) does not contain a traffic card or filler card.
Clear the OPEN-SLOT Alarm
Step 1 Insert a filler card or STM-N card into the empty slot.
Step 2 If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.101 PDI-P
•Not Alarmed (NA), Non-Service Affecting (NSA)
A Payload Defect Indication Path condition indicates a signal label mismatch failure (SLMF) in the VC4 signal. An invalid C2 byte in the SDH path overhead causes an SLMF. The C2 byte is the signal-label byte. This byte tells the equipment what the SDH payload envelope contains and how it is constructed. It enables a SDH device to transport multiple types of services.
The ONS15600SDH encounters an SLMF when the payload, such as an ATM, does not match what the signal label is reporting. The "AU-AIS" condition on page2-14 often accompanies the PDI-P alarm. If the PDI-P is the only alarm reported with the AIS-P, clear the PDI-P alarm to clear the AIS-P alarm. PDI-P can also occur during an upgrade, but usually clears itself and is not a valid alarm.
Warning Invisible laser radiation may 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 100mm may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Caution Always use the supplied ESD wristband when working with a powered ONS15600SDH. Plug the wristband cable into the ESD jack located on the lower-left outside edge of the shelf assembly.
Clear the PDI-P Condition
Step 1 Check the incoming signal overhead with an optical test to verify that the C2 byte is correct; refer to the Cisco ONS15600SDH Procedure Guide for circuit test procedures.
Step 2 If the C2 byte is not correct, it indicates an upstream equipment problem (typically with path-terminating equipment). Troubleshoot the upstream equipment.
Step 3 If the condition does not clear, complete the "2.6.15Remove and Replace a Card" procedure for the reporting card.
Note If the traffic (STM-N) card is implicated and you are able to continue using the traffic card with one port out of service, perform a bridge and roll to move the port traffic to a free port using the "Bridge and Roll Traffic" procedure in the CiscoONS15600SDH Procedure Guide. Label the bad port, and place it out of service until the card can be replaced.
Step 4 If the condition does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.102 PRC-DUPID
•Major (MJ), Service-Affecting (SA) for Ring
•Major (MJ), Non-Service Affecting (NSA) for NE
The Procedural Error Duplicate Node ID alarm indicates that two identical node IDs exist in the same ring. The ONS15600SDH requires each node in the ring to have a unique node ID.
Clear the PRC-DUPID Alarm
Step 1 Log into a node on the ring.
Step 2 Find the node ID by completing the "2.6.1Identify a Ring ID or Node ID Number" procedure.
Step3 Repeat Step 2 for all the nodes on the ring.
Step 4 If two nodes have an identical node ID number, complete the "2.6.4Change a Node ID Number" procedure so that each node ID is unique.

2.5.103 PWR-A
•Minor (MN), Non-Service Affecting (NSA)
The NE Power Failure at Input A alarm applies to the shelf. PWR-A occurs when no power is supplied to the main power distribution unit (PDU). This alarm can be raised if power is connected to the backup PDU but not to the main one because power must be available to both units.
Warning The power supply circuitry for the equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment.
Clear the PWR-A Alarm
Step 1 Verify that both PDU A-side circuit breakers are turned on.
Step 2 Determine whether a power connection between the office power connector and the PDU is present.
Step 3 If the alarm cannot be cleared, verify the continuity of the power connection with a voltmeter using the procedures in the Cisco ONS 15600 SDH Procedure Guide..
Step 4 If the alarm does not clear and if cable continuity is present, remove and reattach (reseat) the cable ends between the office power connector and the PDU.
Step 5 If the alarm does not clear, physically replace the power cable.
Step 6 If the alarm cannot be cleared, physically replace the PDU using the "Remove a Power Distribution Unit" procedure on page3-14.
Step 7 If replacement does not clear the alarm, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country to report a service-affecting problem.
2.5.104 PWR-B
•Minor (MN), Service Affecting (SA)
The NE Power Failure at Input B alarm applies to the NE (node) shelf. It occurs when no power is supplied to the second PDU. This alarm can be raised if power is connected to the main PDU but not to the backup, since power must be available to both units.
Troubleshoot with the "Clear the PWR-A Alarm" procedure . If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
Warning The power supply circuitry for the equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment.
2.5.105 PWR-FA
•Minor (MN), Non-Service Affecting (NSA)
The Backplane Power Fuse Failure alarm indicates that the backplane EEPROM memory 5-VDC fuse fails, but the equipment is still in service. Service is not currently affected, but network management can be affected because the ONS15600SDH system uses a default NE (node) IP address instead of a programmed one in this case. This alarm might be accompanied by the "INVMACADR" alarm on page2-49, which appears in the alarm history when network management capability is restored.
Do not attempt to troubleshoot the alarm. If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of CiscoTAC toll-free numbers for your country.
2.5.106 PWR-FAIL-A
•Major (MJ), Non-Service Affecting (NSA)
The Equipment Power Failure at Connector A alarm occurs when there is no power supply from the main power connector to the equipment. This alarm occurs on the CAP, a CXC card, a traffic (STM-N) card, or a TSC card.
Warning The power supply circuitry for the equipment can constitute an energy hazard. Before you install or replace the equipment, remove all jewelry (including rings, necklaces, and watches). Metal objects can come into contact with exposed power supply wiring or circuitry inside the equipment. This could cause the metal objects to heat up and cause serious burns or weld the metal object to the equipment.
Clear the PWR-FAIL-A Alarm
Step 1 If the "PWR-A" alarm on page2-67 or the "PWR-B" alarm on page2-67 also occurs, troubleshoot it by completing the "Clear the PWR-A Alarm" procedure.
If a PWR-A occurs in addition to PWR-FAIL-A, PWR-A usually clears the lower-hierarchy PWR-FAIL-A alarm. If you clear the PWR-A alarm and the PWR-FAIL-A alarm still remains, continue following this procedure.
Step 2 If a single card has reported the alarm, take the following actions depending what kind of card reported it:
•If the reporting card has an active traffic line port in a 1+1 protection scheme or is part of an SNCP, ensure that an APS traffic switch has occurred to move traffic to the protect port.
–An SNCP APS is identified by an AUTOSW-type alarm or condition (such as AUTOSW-AIS, AUTOSW-LOP-SNCP, AUTOSW-PDI-SNCP, AUTOSW-SDBER-SNCP, AUTOSW-SFBER-SNCP, or AUTOSW-UNEQ-SNCP).
–A 1+1 APS is identified on the node view Maintenance > Protection window. If you click the protection group, in the Selected Group list, the ports are designated as Working/Standby and Protect/Active.
If the reporting port is part of an SNCP, complete the "Switch all SNCP Circuits on a Span" procedure on page 3-4 . If the port is part of a 1+1 group, complete the "Initiate a Force Switch on a 1+1 Port" procedure on page 3-4 . Continue with Step 4 .
•If an automatic switch to the alternate copy CXC card occurred, the CXC card can be serviced. If the switch has not occurred, complete the "2.6.6 Request a Cross-Connect Card Preferred Copy Switch" procedure . Continue with Step 4 .
To determine which CXC card is the preferred copy and if it is currently being used, open the node view Maintenance > Preferred Copy window. The Data Copy area Preferred field shows Copy A or Copy B. The Currently Used field shows the copy being used.
Note In CTC, CopyA refers to the CXC card in Slot 6/7. CopyB refers to the CXC card in Slot8/9. Either copy can be chosen as the preferred copy CXC card. The other CXC card is called the alternate CXC card in this chapter.
Step 3 If the alarm is reported against a TSC card, complete the "2.6.8Hard-Reset the TSC Using CTC" procedure.
Step 4 If the alarm is reported against a traffic (STM-N) card or CXC card, perform a hard reset (or soft reset on the CXC card):
Caution Use hard resets with caution. There can be up to 15 other sets of bandwidth affected by a hard reset. A forced hard reset of a CXC card will cause a service disruption.
Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the timing source because the Stratum 3E timing module is being adopted.
a. Position the cursor over the active card.
b. Right-click and choose Hard-reset Card (or Soft-reset Card ) from the shortcut menu.
c. Click Yes in the Hard-reset Card (or Soft-reset Card) dialog box.
Step 5 If the alarm does not clear, remove and reinsert (reseat) the reporting card:
a. Open the card ejectors.
b. Slide the card out of the slot.
c. Check the pins one the backplane connector, including the power pins on the edge of the card. Also inspect the pins on the backplane as well. A bent pin can cause power failure.
Caution If a backplane pin is bent, do not insert another card in the slot until the problem is remedied.
d. Slide the card into the slot along the guide rails.
e. Close the ejectors.
Step 6 If the alarm does not clear, complete the "2.6.15Remove and Replace a Card" procedure for the reporting card.
Step 7 If the single card reseat and replacement does not clear the alarm, or if multiple cards report the alarm, verify the office power; refer to the CiscoONS15600SDH Procedure Guide for instructions.
Step 8 If the alarm does not clear, reseat the power cable connection to the connector. For more information about ONS15600SDH power connections, refer to the CiscoONS15600SDH Procedure Guide.
Step 9 If the alarm does not clear, physically replace the power cable connection to the connector.

Step 2 If the alarm does not clear, log on to http://www.cisco.com/tac for more information or log into http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml to obtain a directory of Cisco Technical Assistance Center (TAC) toll-free numbers for your country to obtain more information.
2.5.145 UPGRADE
•Not Alarmed (NA), Non-Service Affecting (NSA)
The System Upgrade in Progress condition indicates that a system upgrade is occurring on the TSC card.
When software is downloaded, it is loaded into the available code volume on the active TSC card. The software is copied to the available code volume on the standby TSC card next. The "SFTWDOWN" condition on page2-73 occurs at that time. When the user activates the load, the UPGRADE condition occurs.
Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the timing source because the Stratum 3E timing module is being adopted.
2.5.146 WTR
•Not Alarmed (NA), Non-Service Af]fecting (NSA)
The Wait to Restore condition indicates that revertive switching is specified and that a switch to protection occurred. When the working path is viable, this condition occurs while the wait to restore timer has not expired. The condition clears when the timer expires and traffic switches back to the working path.
2.5.147 XCMTX
•Critical (CR), Service Affecting (SA)
The Unavailable Cross-Connection Matrix Equipment alarm indicates no cross-connection matrix on the NE (node). If there was previously a single CXC card running in unprotected mode, that card fails. If there were two cards running in protected mode, the matrix has become unavailable on both. Troubleshoot with the "Clear the UNPROT-XCMTX Alarm" procedure.

2.6.7 Soft-Reset the TSC Card Using CTC
This procedure is used to force system control from the active TSC card to the standby TSC card. In this kind of reset, the card is rebooted but the flash memory is not cleared.
Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.
Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the timing source because the Stratum 3E timing module is being adopted.
Step 1 Determine which TSC card is active and which is standby.
Position the cursor over the active card. An active TSC card has a green ACT STBY LED illuminated.
Step 2 Right-click the active TSC card to reveal the shortcut menu.
Step 3 Click Soft-reset Card .
Step 4 Click Yes when the confirmation dialog box appears.
Step 5 Click OK when the "Lost connection to node, changing to Network View" dialog box appears.

Step 6 Confirm that the TSC card you reset is in standby mode after the reset.
A TSC card that is ready for service has a green SRV LED illuminated. An active TSC card has a green ACT STBY LED illuminated, but a standby card does not have this LED illuminated.
Tip If you run the cursor over the TSC card in CTC, a popup displays the card's status (whether active or standby).
2.6.8 Hard-Reset the TSC Using CTC
This procedure is used to force system control from the active TSC card to the standby TSC. This kind of reset reboots the card and clears the flash memory, making it appear like a newly inserted card.
Warning Do not reach into a vacant slot or chassis while you install or remove a module or a fan. Exposed circuitry could constitute an energy hazard.
Caution Use hard resets with caution. There can be up to 15 other sets of bandwidth affected by a hard reset.
Note When a TSC card changes from active to standby, the node takes approximately 12 minutes to synchronize completely to the timing source because of the more accurate G.813 timing module being adopted.
Step 1 Determine which TSC card is the active card and which is the standby card.
Position the cursor over the active card. An active TSC card has a green ACT STBY LED illuminated.
Step 2 Right-click the active TSC card to reveal the shortcut menu.
