4.1 Air Filter Inspection
The ONS 15454 SDH contains a reusable filter that you should remove and visually inspect approximately every 30 days, depending on the cleanness of the operating environment. For more information about filter brackets and air filter installation, see Chapter 1 in the Cisco ONS 15454 SDH Installation and Operations Guide.
The air filter is made of gray, open-celled, polyurethane foam that is specially coated to provide fire and fungi resistance. Figure 4-1 illustrates a reusable fan tray air filter in an external filter bracket.
If the air filter is inside the fan-tray assembly, go directly to the "Fan-Tray Assembly" procedure to remove the fan tray.

Step 1 Slide the filter out of the external filter brackets. Be careful not to dislodge any dust that could have collected on the filter.
Step 2 Visually inspect the filter for dirt and dust.
Step 3 If the air filter has a concentration of dirt and dust, vacuum the filter or wash the filter under a faucet with a light detergent.
Note If possible, clean the filter outside of the operating environment to avoid releasing dirt and dust near the equipment.
Step 4 If you washed the filter, allow it to air-dry at least 8 hours (or use spare filter).
Caution Do not put a damp filter back in the ONS 15454 SDH.
Step 5 Slide the filter to the back of the brackets.
4.2 Fan-Tray Assembly
To replace the fan-tray assembly (FTA), it is not necessary to move any of the cable management facilities. You can remove the fan-tray assembly using the retractable handles and replace it by pushing until it plugs into the receptacle on the back panel.

Step 1 Open the front door of the shelf assembly.
a. Open the front door lock.
The ONS 15454 SDH comes with a pinned hex key for locking and unlocking the front door. Turn the key counterclockwise to unlock the door and clockwise to lock it.
b. Press the door button to release the latch.
c. Swing the door open.
Step 2 Remove the front door (optional). If you do not want to remove the door, proceed to Step 3.
a. Detach the ground strap from either the door or the chassis by removing one of the Kepnuts.
b. Place the Kepnut back on the stud after the ground strap is removed to avoid misplacement.
c. Secure the dangling end of the ground strap to the door or chassis with tape.
Step 3 Push the outer side of the handles on the fan-tray assembly to expose the handles.
Step 4 Fold out the retractable handles at the outside edges of the fan tray.
Step 5 Pull the handles and slide the fan-tray assembly one inch out of the shelf assembly and wait until the fans stop.
Step 6 When the fans have stopped, pull the fan-tray assembly completely out of the shelf assembly.
Caution The ONS 15454 SDH system is now without forced-air cooling. The FTA must be placed back in service as quickly as possible to avoid system damage.
Step 7 If you are replacing the fan-tray air filter and it is installed beneath the fan-tray assembly, slide the existing air filter out of the shelf assembly and replace it before replacing the fan-tray assembly.
If you are replacing the fan-tray air filter and it is installed in the external bottom bracket, you can slide the existing air filter out of the bracket and replace it at any time. For more information on the fan-tray air filter, see the "Air Filter Inspection" section.
Step 8 Slide the new fan tray into the shelf assembly until the electrical plug at the rear of the tray plugs into the corresponding receptacle on the backplane.
The fans should start running immediately.
Step 9 To verify that the tray has plugged into the backplane, check that the LCD on the front of the fan tray is activated.
Step 10 If you replace the door, also reattach the ground strap.
Step 11 Close and lock the door.
4.3 System Reset
You can reset the ONS 15454 SDH TCC-I cards by using the Cisco Transport Controller (CTC) software or by physically resetting a TCC-I card (card pull). A software-initiated reset reboots the TCC-I card and reloads the operating system and the application software. If a card pull is performed, it carries out these tasks and temporarily powers down the TCC-I card, clearing all buffer memory.
You can initiate a software reset for an active TCC-I card or a standby TCC-I card without affecting traffic. But a card pull should only be performed on a standby TCC-I. If you need to pull an active TCC-I card, first you should initiate a software reset on a card to put it into standby mode.
Procedure: Initiate a Software Reset

Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.
Caution During the reboot period, there is no TCC-I redundancy.
Note To determine whether the TCC-I card is in active mode or standby mode, view it in the CTC software and position the cursor over the TCC-I card graphic to display the status.
Step 1 If you need to perform a card pull on an active TCC-I card, initiate a software reset on the active TCC-I card first. (See the "Initiate a Software Reset" procedure.)
Step 2 When the TCC-I is in standby mode, unlatch the top and bottom ejector levers on the TCC-I card.
Step 3 Pull the card outward from the slot until the lighted LEDs turn off.
Step 4 Wait 30 seconds. Reinsert the card and close the ejector levers.
Note The TCC-I card takes several minutes to reboot and display the amber standby LED after rebooting.
Note During bootup of the reinserted TCC-I card, the FMEC cards in the system will not be visible in the CTC software. They will be visible in the software again after the TCC-I card has finished booting.
Note When a second TCC-I card is inserted into the shelf, it will synchronize its software, its backup software, and its database with the active TCC-I. If its software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy from the active TCC-I. This copying will take about 15 to 20 minutes. If its backup software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy the backup software from the active TCC-I. This copying, again, will take about 15 to 20 minutes. Copying the database from the active TCC-I will take about 3 minutes. So, depending on the software existing in the new TCC-I, booting it up will take between 3 and about 40 minutes.
4.4 Database Backup and Restoration
When dual TCC-I cards are installed in the ONS 15454 SDH, each TCC-I card hosts a separate copy of the database. If the working TCC-I card database fails, the protect card database is available. You can store a backup version of the database on a CTC software workstation. This off-system storage should be part of regular ONS 15454 SDH maintenance at approximately weekly intervals. It should also be performed to prepare an ONS 15454 SDH for disasters.
Note E100T-G cards lose traffic for approximately 30 seconds when an ONS 15454 SDH database is restored. The CARLOSS alarm appears and clears during this process. The traffic outage happens during the spanning-tree reconvergence.
Note If you are restoring the database on multiple nodes, wait five minutes between each database restoration.
Note The following parameters are not backed up and restored: node name, IP address, mask and gateway, and IIOP port. If you change the node name and then restore a backed-up database with different node names, the circuits will map to the new node name. Cisco recommends keeping a record of the old and new node names.

4.5 Restore the Node to Factory Configuration
Purpose
|
Use this procedure to initiate a process that will automatically load and activate a software package and restore the database from a database backup file that was obtained at the time of installation. This process is performed with the RE-INIT.jar utility, also called the reinitialization (reinit) tool.
|
Tools/Equipment
|
CD containing the software, the node's NE defaults, and the reinitialization tool. JRE 1.3.1_02 must also be installed on the computer you will use to perform this procedure.

|
Caution If you are restoring the database on multiple nodes, wait until the TCC-I cards have rebooted on each node before proceeding to the next node.
Caution Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinitialization tool will choose the first product-specific software package in the specified directory if you only use the Search Path field. You may accidentally copy an incorrect database if multiple databases are kept in the specified directory.
Note If the software package files and database backup files are located in different directories, complete the Package and Database fields ( Figure 4-7).
Note The following parameters are not backed up and restored: node name, IP address, mask and gateway, and IIOP port. If you change the node name and then restore a backed up database with a different node name, the circuits will map to the new renamed node. Cisco recommends keeping a record of the old and new node names.
Step 1 If you need to install or replace one or more TCC-I cards, see the Cisco ONS 15454 SDH Installation and Operations Guide or the "Procedure:Replace a TCC-I Card" task.
Step 2 If you are using Microsoft Windows, complete the "Procedure:Use the Reinitialization Tool in Windows" task.
Step 3 If you are using UNIX, complete the "Procedure:Use the Reinitialization Tool in Unix" task.
You can use the reinitialization tool to upload the software package, restore the node's database, or both by checking the appropriate fields shown below in Figure 4-7. The default setting for this tool is shown with both upload package (software) and restore database selected.

4.6 Card Replacement
Cards can be replaced with the same type of card or with a different type.
•To replace an ONS 15454 SDH card with another card of the same type, you do not need to change the database. Pull the old card and replace it with a new one.
•To replace a card with a different type of card, pull the card and replace it with a new one. Then delete the original card in the CTC software.
Note An improper removal (IMPROPRMVL) alarm occurs whenever a card pull is performed unless the card is deleted in the CTC software first. The alarm will clear after the card replacement is complete.
Caution Always use an ESD wristband when working with an ONS 15454 SDH. Plug the wristband cable into the ESD jack located on the mid-right outside of the shelf assembly.
Note Traffic can be interrupted when you pull an active card from the ONS 15454 SDH. Use caution when replacing cards and verify that only inactive or standby cards are being replaced. If an active card needs to be replaced, switch it to standby mode as shown in the "Replace an In-Service XC10G Card" section, the "Replace an In-Service STM-N Card in 1+1 Configuration" section, or the "Replace an In-Service Electrical Card (E1-N-14, DS3i-N-12, or E3-12)" section, before pulling the card from the node.

Caution Hazardous voltage or energy may be present on the backplane when the system is operating. Use caution when servicing.
Note Resetting an XC10G card can cause a linear 1+1 STM-N protection switch or an MS-SPRing protection switch.
Note Traffic can be interrupted when you pull an active card from the ONS 15454 SDH. Use caution when replacing cards and verify that only inactive or standby cards are being replaced. If an active card needs to be replaced, follow the procedure to switch the XC10G card to standby mode before you pull the card from the node.
Step 1 Take these precautions before initiating an XC10G card reset to avoid causing a linear 1+1 or MS-SPRing protection switch.
a. Ensure that the working span is active on the local and remote nodes.
b. Ensure that the working span is carrying error-free traffic without SD alarms or SF alarms.
c. Place a lockout on the protection span before initiating an XC10G reset. (For information about placing lockouts, refer to the ONS 15454 SDH Installation and Operations Guide.) In an MS-SPRing, place a lockout on the East and West node cards adjacent to the XC10G switch node. For example, if you are switching the XC10G on Node B, place a lockout on the Node A West card and on the Node C East card. You do not need to place lockouts on Node B.
<------East [Node A] West------East [Node B] West------East [Node C] West------>
Before setting the lockout, verify that the MS-SPRing is not switched. Traffic can be lost if the MS-SPRing is switched when the lockout is set. In a 1+1 protection scheme, place a lockout on the protect card and verify that traffic is traveling over the working span before setting the lockout.
Step 2 Determine which XC10G card is active. The active card ACT/STBY LED is green. The standby card ACT/STBY LED is yellow.
Note You can determine whether the XC10G card is in active mode or standby mode by viewing it in the CTC software and positioning the cursor over the XC10G card graphic to display the status.
If the card to be replaced is already standby, go to Step 4.
Step 3 Switch the active XC10G card to standby.
a. In the node view, click the Maintenance > XC Cards tabs.
b. In the Cross Connect Cards area, click Switch.
c. Click Yes on the Confirm Switch dialog box.
Note After the active XC10G goes into standby mode, the original standby slot becomes active. This causes the former standby card ACT/STBY LED to become green.
Step 4 Pull the standby XC10G card from the ONS 15454 SDH.
Step 5 Insert the replacement XC10G card into the empty slot. The replacement card boots up and becomes ready for service after approximately one minute.
Step 6 Release the protection lockouts.

Note When a second TCC-I card is inserted into the shelf, it will synchronize its software, its backup software, and its database with the active TCC-I. If its software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy from the active TCC-I. This copying will take about 15 to 20 minutes. If its backup software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy the backup software from the active TCC-I. This copying, again, will take about 15 to 20 minutes. Copying the database from the active TCC-I will take about 3 minutes. So, depending on the software existing in the newly inserted TCC-I, booting it up will take between 3 and about 40 minutes.

Note An STM-N reset can cause a linear 1+1 STM-N protection switch or an MS-SPRing protection switch.
Note For optical cars in 1+1 configurations, there will be an active card and a standby card. For SNCP and MS-SPRing configurations, both STM-N cards will be active. Traffic will be interrupted on SNCPs and MS-SPRings if you reset a traffic-bearing card with protection switching disabled.
Note The STM-N card should be replaced if a red FAIL LED appears.
Warning Class I (21 CFR 1040.10 and 1040.11) and Class 1M (IEC 60825-1 2001-01) laser products.
Warning Invisible laser radiation may be emitted from the end of the unterminated fiber cable or connector. Do not stare into the beam or view 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 may pose an eye hazard. Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation exposure.
Step 1 If the card to be reset is a standby card, right-click the card and choose Reset Card from the shortcut menu.
If the card is not standby, go to Step 2.
Step 2 To avoid causing a linear 1+1 or MS-SPRing protection switch, ensure that the working span is active on the local and remote nodes.
Step 3 Ensure that the working span is carrying error-free traffic without FAIL alarms or SF alarms.
Step 4 Perform a lockout on the protection span in the CTC software before initiating an STM-N card reset. In an MS-SPRing, place a lockout on the East and West node cards adjacent to the XC10-G switch node. For example, if you are switching the XC10-G on Node B, place a lockout on the Node A West card and on the Node C East card.
<------East [Node A] West------East [Node B] West------East [Node C] West------>
You do not need to place lockouts on Node B. Before setting the lockout, verify that the MS-SPRing is not switched. Traffic can be lost if the MS-SPRing is switched when the lockout is set. In a 1+1 protection scheme, place a lockout on the protect card and verify that traffic is traveling over the working span before setting the lockout.

4.7 Span Upgrade
A span includes the set of optical fiber ("lines") between two ONS 15454 SDH nodes. A span upgrade raises the STM-N signal transmission rate of all the lines constituting the spans. It is done by coordinated line upgrades that move traffic from lower-rate optical card(s) to higher-rate optical card(s). No other span attributes are changed.
Only single-port cards can be upgraded. You can upgrade the following ONS 15454 SDH cards in an in-service span:
•STM-4 to STM-16
•STM-4 to STM-64
•STM-16 to STM-64
When a span is upgraded, the higher-rate line card must replace the lower-rate card in the same slot. If the spans to be upgraded are part of a ring topology, all spans in the ring must be upgraded. The protect configuration (two-fiber MS-SPRing, four-fiber MS-SPRing, or 1+1) that was used with lower-rate optical card is retained in the higher-rate upgrade.
Span upgrades can be performed using the CTC software upgrade wizard, or they can be performed manually. To use the wizard, follow the procedure in the "Span Upgrade Wizard" section. To upgrade a span manually, follow the procedures in the "Manual Span Upgrades" section.
Note Span upgrades do not change SDH topologies. For example, a 1+1 scheme is not upgraded to a two-fiber MS-SPRing during a span upgrade. See the SDH Topologies chapter in the Cisco ONS 15454 SDH Installation and Operations Guide for topology upgrade procedures.
4.7.1 Span Upgrade Wizard
The Span Upgrade Wizard automates all steps in the manual span upgrade procedure (MS-SPRing and 1+1). The Wizard can upgrade both lines on one side of a four-fiber MS-SPRing or both lines of a 1+1 group. The Wizard upgrades MSPs and two-fiber MS-SPRings one line at a time. The Span Upgrade Wizard requires that spans have DCC enabled.
Note The CTC software Span Upgrade Wizard only supports STM-N span upgrades. It does not support electrical card upgrades.
Note During the span upgrade, minor alarms and conditions will occur and clear automatically. However, no service-affecting alarms (SA, Major, or Critical) should be expected. If any service-affecting alarms occur, Cisco recommends backing out of the procedure.

Note If an abnormal error occurs while you are using the Span Upgrade Wizard, you must exit the wizard and initiate the manual procedure to finish the upgrade, or you must back out of the procedure. If you continue the upgrade manually, examine the standing conditions and alarms to identify the stage where the wizard failure occurred.
Note If you are upgrading a 1+1 group, upgrade the protect line first, regardless of which line is active.
Note You cannot downgrade if circuits exist on the STM-Ns that would be removed (i.e., the higher STM-Ns).
Step 1 Ensure no alarms or conditions are present on the span to be upgraded. An unresolved alarm or condition will likely cause the wizard to fail.
Step 2 In the network view, right-click the span to be upgraded.
Step 3 Choose Span Upgrade from the shortcut menu ( Figure 4-10).

4.7.2 Manual Span Upgrades
The manual upgrade procedures require at least two technicians (one at each end of the span). The technicians must be able to communicate with each other during the upgrade. The upgrade procedures do not affect service. They cause no more than three switches with switch times of less than 50 ms.
During upgrade, some minor alarms and conditions occur and clear automatically. However, no service-affecting alarms (SA, Major, or Critical) should be expected. If any service-affecting alarms occur, Cisco recommends backing out of the procedure. Choose from four manual span upgrade options.

Step 1 Identify the node to be powered down. If no cards are installed, go to Step 14. If one or two TCC-I cards are installed, log into the node.
Step 2 From the CTC software network view, log into the node and verify that the node is not connected to a working network.
To determine whether the node is part of a working network, click Go to the Network View in the CTC node view, and determine whether the node is connected to other nodes on the map by spans.
To determine what kind of configuration the node is included in (if it is still part of a working network), log into the node if you have not done so already and click the Provisioning > MS-SPRing tab in the CTC node (default login) view. If a ring is present on the tab, the node is part of a two- or four-fiber MS-SPRing. If it is not present, but still shown on the network view map, it is an SNMP or linear ADM node.
•If the node is part of a working network, log out of the node and refer to the Cisco ONS 15454 SDH Installation and Operations Guide for procedures to remove nodes. Then continue with Step 3.
•If the node is not connected to a working network and the current configurations are no longer required, go to Step 3.
Note Current configurations will be saved if Steps 3 to 10 are skipped.
Step 3 From the node view, click the Circuits tab and verify that no circuits are displayed. If circuits are displayed, delete all the circuits that originate or terminate in the node.
a. Click the circuits that need to be deleted and click Delete.
b. Click Yes in the Delete Circuits dialog box.
If no circuits are displayed, skip to Step 4.
Step 4 From the node view, choose the Provisioning > Protection tabs and delete all protection groups.
Step 5 From the node view, choose the Provisioning > SDH DCC tabs and delete all SDCC terminations.
Step 6 Click Yes in the Delete SDCC Terminations dialog box and Yes in the "Are you sure?" confirmation dialog box.
Step 7 For an installed line card, from the card view, click the Provisioning > Line tabs and place all ports in the OOS state by clicking the row for each port under the State column and choosing OOS from the list box.
Step 8 Click Apply and Yes in the Confirmation Dialog.
Step 9 Remove all fiber connections to the cards.
Step 10 Right-click the installed line card in CTC and click Delete from the shortcut menu.
Step 11 Click Yes in the "Are you sure?" confirmation dialog box.
Step 12 After you have deleted the line card, open the card ejector handles for each card and pull it from the node. Repeat Steps 7 to 12 for each installed line card.
Step 13 Turn off the power of the power supply that feeds the node.
Step 14 Disconnect the power cables from the external source.
Step 15 Disconnect the power cables from the MIC-A/P and MIC-C/T/P cards.
Step 16 Remove all the remaining common cards and FMEC cards from the node.
Step 17 Store all pulled cards and update inventory records according to local site practice.
4.10 Powering Up a Node
Note Always use the ESD wristband when working with the Cisco ONS 15454 SDH. Plug the wristband into the ESD jack located on the fan-tray assembly or on the lower right outside edge of the shelf assembly. To access the ESD plug on the shelf assembly, open the front door of the Cisco ONS 15454 SDH. The front door is grounded to prevent electrical shock.

Step 1 Make sure that the fan trays are installed in the shelf. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 2 Install the first TCC-I card in the shelf. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 3 Install the MIC-A/P in Slot 23 and the MIC-C/T/P card in Slot 24 of the shelf. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 4 Connect the power cables to the power supply inputs of the MIC-A/P and the MIC-C/T/P.
Step 5 Connect the other ends of the power cables to the power distribution panel. Refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 6 Turn on both power switches on the power distribution panel.
Step 7 Ensure that the fans are running.
Step 8 Wait until the first TCC-I card has finished its startup procedure. The startup procedure takes about three minutes and is finished when the IP address is to displayed on the LCD of the fan unit.
Step 9 Install the second TCC-I.
Note When a second TCC-I card is inserted into the shelf, it will synchronize its software, its backup software, and its database with the active TCC-I. If its software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy from the active TCC-I. This copying will take about 15 to 20 minutes. If its backup software version does not match the version on the active TCC-I, the newly inserted TCC-I will copy the backup software from the active TCC-I. This copying, again, will take about 15 to 20 minutes. Copying the database from the active TCC-I will take about 3 minutes. So, depending on the software existing in the new TCC-I, booting it up will take between 3 and about 40 minutes.
Step 10 Install the first and the second XC10G cards. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 11 Install the optical line cards required for the configuration to be set up.For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 12 Install the electrical line cards required for the configuration to be set up. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 13 Install the FMECs required for the configuration to be set up. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 14 Check with the fiber video videos cope and, if necessary, clean each fiber connector using the procedures in Inspect and Clean Fiber Connectors.
Step 15 Install all fiber connections to the cards as required for the configuration to be set up. For instructions, refer to the Cisco ONS 15454 SDH Installation and Operations Guide.
Step 16 Configure the node according to the Cisco ONS 15454 SDH Installation and Operations Guide.
