Note 
The terms "Unidirectional Path Switched Ring" and "UPSR" may appear in Cisco literature. These terms do not refer to using Cisco ONS 15xxx products in a unidirectional path switched ring configuration. Rather, these terms, as well as "Path Protected Mesh Network" and "PPMN," refer generally to Cisco's path protection feature, which may be used in any topological network configuration. Cisco does not recommend using its path protection feature in any particular topological network configuration.
This chapter provides procedures for maintaining the Cisco ONS 15600.

Cisco recommends that you inspect the air filter monthly, and clean the filter every three to six months. Replace the air filter every two to three years. Avoid cleaning the air filter with harsh cleaning agents or solvents.
Step 1 Remove the front door of the shelf assembly by completing the following substeps. If the front door is already removed, continue with Step 2.
a. Locate the latches on the bottom left and right sides of the door.
b. Pull each latch outward to release the latch.
c. Swing the door up to open it.
d. Lift the door off its hinge pins and remove it. Set the door aside so you can reinstall it after you complete this procedure.
Step 2 Gently remove the air filter from the shelf assembly (Figure 14-1). Be careful not to dislodge any dust that may have collected on the filter.
Figure 14-1 Removing a Reusable Air Filter (Front Door Removed)
Step 3 Visually inspect the white filter material for dirt and dust.
Step 4 If the reusable air filter contains a concentration of dirt and dust, replace the dirty air filter with a clean air filter (spare filters should be kept in stock) and reinsert the fan-tray assembly. Then, vacuum the dirty air filter or wash it under a faucet with a light detergent.
Do not leave the fan tray out of the chassis for an extended period of time because excessive heat can damage the ONS 15600 cards.
Note Cleaning should take place outside the operating environment to avoid releasing dirt and dust near the equipment.
Step 5 If you washed the filter, allow it to completely air dry for at least eight hours.
Do not put a damp filter back in the ONS 15600.
Step 6 Reinstall the front door of the shelf assembly:
a. Insert the front door (removed in Step 1) into the hinge pins on the shelf assembly.
b. Lower the door onto the face of the shelf assembly.
c. Pull the metal latches on the door outward and gently push the door toward the shelf, making sure no optical cables are caught or pinched in the door.
d. Click the latches in place and release.
Stop. You have completed this procedure.

Restoring an out-of-date database or a database from a different node might affect the service. Any provisioing data that currently exists on the node, but not present in the database file being restored, will be deleted.
Note The following parameters are not backed up and restored: Node name, subnet 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.
Note You need separate backups for each node in a circuit path to be able to restore the entire circuit.
Note If you want to revert to a previously loaded software version, refer to the platform-specific upgrade document for instructions.
Step 1 Complete the "DLP-E26 Log into CTC" task at the node where you are performing the database restore. If you are already logged in, continue with Step 2.
Step 2 In node view, click the Maintenance > Database tabs.
Step 3 Click Restore.
Step 4 In the Database Restore window, click the Alarms check box and/or Performance check box to choose these database items in addition to provisioning information.
Note You can back up five databases as part of one back up file package; therefore the 15600 allows you to select all of the files or a subset of the files to restore as part of the restore package.
Step 5 In the Database Restore window, click Browse.
Step 6 Navigate to the backup file stored on the workstation hard drive or on network storage.
Step 7 Click the database file to highlight it.

NTP-E177 Restore the Node to Factory Configuration
Purpose |
This procedure reinitializes the ONS 15600 using the CTC reinitialization tool. Reinitialization uploads a new software package to the control card, clears the node database, and restores the factory default parameters. |
Tools/Equipment |
Cisco ONS 15600 System Software CD, Version 6.0.x JRE 1.4.2 must be installed on the computer to log into the node at the completion of the reinitialization. The reinitialization tool can run on JRE 1.3.1_02 or JRE 1.4.2. |
Prerequisite Procedures |
One of the following: • • |

Security Level |
Superuser |
Cisco strongly recommends that you keep different node databases in separate folders. This is because the reinit tool chooses the first product-specific database in the specified directory if you use the Search Path field instead of the Package and Database fields. You may accidentally copy an incorrect database if multiple databases are kept in the specified directory.
Restoring a node to the factory configuration deletes all cross-connects on the node.
Cisco recommends that you take care to save the node database to safe location if you are not restoring the node using the database provided on the software CD.
Note The following parameters are not backed up and restored when you delete the database and restore the factory settings: node name, IP address, subnet 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 map to the new renamed node. Cisco recommends keeping a record of the old and new node names.
Step 1 If you are using Microsoft Windows, complete the "DLP-E144 Use the Renitialization Tool to Clear the Database and Upload Software (Windows)" task.
Step 2 If you are using UNIX, complete the "DLP-E200 Use the Renitialization Tool to Clear the Database and Upload Software (UNIX)" task.
Stop. You have completed this procedure.
NTP-E72 Initiate an External Switching Command on an Optical Protection Group
Note If you choose a Manual switch, the command will switch traffic only if the path has an error rate less than the signal degrade bit error rate threshold. A Force switch will switch traffic even if the path has SD or SF conditions. A Force switch has a higher priority than a Manual switch. Lockouts can only be applied to protect cards; they prevent traffic from switching to the protect port under any circumstance. Lock outs have the highest priority. A lock on can be applied to the working port; it prevents traffic from switching to the protect port in the protection group.
Step 1 Complete the "DLP-E26 Log into CTC" task at the node where you want to inhibit 1+1 group protection switching. If you are already logged in, continue with Step 2.
Step 2 Complete the "DLP-E99 Initiate a Manual Switch on a Port in a 1+1 Protection Group" task as needed.
Step 3 Complete the "DLP-E100 Initiate a Force Switch on a Port in a 1+1 Protection Group" task as needed.

NTP-E117 Replace a TSC 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. Statement 206
|
Note When an error is detected on a TSC card, the ONS 15600 system switches control to the second TSC card; therefore, so it should not be necessary to change control when you replace the card.
Note You do not need to make any changes to the database if you are replacing it with a card of exactly the same type.
Note Card removal raises an improper removal (IMPROPRMVL) alarm, but this clears after the card replacement is completed.
Step 1 Complete the "DLP-E26 Log into CTC" task at the node where you will replace the TSC card.
Step 2 To ensure that the card you are replacing is not the active TSC card, run the mouse over the card in CTC. If the card says Active, switch it to Standby:
a. Right-click the active TSC card to reveal the shortcut menu.
b. Click Soft-reset Card.
c. Click Yes when the confirmation dialog box appears.
d. Click OK when the "Lost connection to node, changing to Network View" dialog box appears.
Note The TSC card takes several minutes to reboot. See Table 2-1 for more information about LED behavior during TSC card reboots.
Note Whenever TSC cards are changed from active to standby, it takes approximately 12 minutes to completely synchronize to the new system clock source due to the more accurate Stratum 3E timing module being adopted.
Step 3 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).
Step 4 Physically remove the card you want to replace from the ONS 15600:
a. Open the card ejectors.
b. Slide the card out of the slot.
Step 5 Insert the replacement TSC card into the empty slot:
a. Open the ejectors on the replacement card.
b. Slide the replacement card into the slot along the guide rails until it contacts the backplane.
c. Close the ejectors.
Step 6 If you want to make the replaced TSC card active, complete Steps 2b through 2d again.
Stop. You have completed this procedure.
NTP-E118 Replace a Fan Tray
Do not force a fan tray into place. Forcing a fan tray can damage the connectors on the fan tray or the connectors on the back panel of the shelf assembly.
The center fan tray (tray 2) in the ONS 15600 shelf is the most critical tray because it cools the common control cards. If both fans in this tray are inoperative, CTC initiates a five-minute countdown to shut down one of the SSXC cards. You should swap a working fan tray (tray 1 or 3) with tray 2 as soon as possible to prevent equipment damage.
When a fan tray is removed from a shelf assembly, it momentarily creates the same situation that occurs if two fans in a single tray fail. In this situation (that is, the system is running on two fans), CTC software begins a five-minute countdown before shutting down SSXC card operation in order to protect the cards. Replace the fan tray in the shelf assembly as quickly as possible to avoid SSXC card shutdown.
Note The ONS 15600 system requires at least one working fan in each of the three fan trays. When a single fan in a tray fails, Cisco recommends replacing the tray with a fully working tray as soon as practically possible. To replace a fan tray, it is not necessary to move any of the cable management facilities.
Note Each fan tray contains two fans. The FAN LED indicates if one or both fans fail in a fan tray.
Step 1 Lift the latch on the fan tray that you want to replace, and pull the fan tray away from the shelf assembly.
Step 2 Insert the new fan tray in the shelf assembly.
Step 3 Press the latch down to secure the fan tray.
Stop. You have completed this procedure.
NTP-E119 Replace the Customer Access Panel
Note The 15600 node is viewable only when CTC is connected to its front panel. You will not be able to view any other node that is connected to the ONS 15600 through a DCC.
Step 1 Remove any tie wraps and cables attached to the CAP (Figure 14-5).
Figure 14-5 CAP Faceplate and Connections
Step 2 Remove the pin-field card, leaving the wires attached if possible. (If this is not possible, remove and label the wires.)
Step 3 To remove the CAP:
a. Remove the 14 screws on the left and right sides of the CAP using a 3/16-inch socket.
b. Remove the 17 nuts on the top and bottom of the CAP using a 1/4-inch socket.
c. Loosen the center bolt using a 7/16-in. socket. This creates an extraction force on the connectors to successfully unmate them.
d. Pull the CAP off of the alignment pins.
Step 4 Place the replacement CAP over the alignment pins on the backplane and tighten the center bolt using a 7/16-inch socket. This creates an insertion force that successfully mates the connectors.
Step 5 Verify that the CAP cover is contacting the rear cover around the CAP perimeter.
Step 6 Replace the CAP screws and tighten to the specified torque (6 to 7 foot pounds).
Step 7 If you removed the wire-wrap wires from the pin field card, replace them on the pin field according to their labeled positions. If you removed the pin field card with the wires intact, reinstall the pin field card.
Step 8 Replace the tie wraps and cables.
Stop. You have completed this procedure.
NTP-E120 Remove a Power Distribution Unit
Note The PDU can be ordered in entirety (including PDU-A, PDU-B, and alarm panel), or by part.
Step 1 Remove a PDU from a donor unit:

NTP-E180 Edit Network Element Defaults
Note For a list of card and node default settings, refer to the "Network Element Defaults" appendix in the Cisco ONS 15600 Reference Manual. To change card settings individually (that is, without changing the defaults), see Chapter 10 "Change Card Settings." To change node settings, see Chapter 11 "Change Node Settings."
Step 1 Complete the "DLP-E26 Log into CTC" task at the node where you want to edit NE defaults.
Step 2 Click the Provisioning > Defaults tabs.
Step 3 Under Defaults Selector, choose a card type (if editing card-level defaults), CTC (if editing CTC defaults), or NODE (if editing node-level defaults). Clicking on the node name (at the top of the Defaults Selector column) lists all available NE defaults in the Default Name column. To selectively display just the defaults for a given card type, for node-level, or for CTC-level, you can drill down the Defaults Selector menu structure.
Step 4 Locate a default you want to change under Default Name.
Step 5 Click in the Default Value column for the default property you are changing and either choose a value from the drop-down menu (when available), or type in the desired new value.
Note If you click Reset before you click Apply, all values will return to their original settings.
Step 6 Click Apply (click in the Default Name column to activate the Apply button if it is unavailable). You can modify multiple default values before applying the changes.
A pencil icon will appear next to any default value that will be changed as a result of editing the defaults file.
Step 7 If you are modifying node-level defaults, a dialog box appears telling you that applying defaults for node level attributes overrides current provisioning and asks if you want to continue. Click Yes.
If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.
Note Changes to most node defaults reprovision the node when you click Apply. Changes made to card settings using the Defaults Editor do not change the settings for cards that are already installed or slots that are preprovisioned for cards, but rather, change only cards that are installed or preprovisioned thereafter. To change settings for installed cards or pre-provisioned slots, see Chapter 10 "Change Card Settings."
Note Changing some NE defaults can cause CTC disconnection or a reboot of the node in order for the default to take effect. Before you change a default, view the Side Effects column of the Defaults editor (right-click a column header and select Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for that default.
Stop. You have completed this procedure.
NTP-E181 Import Network Element Defaults
Note For a list of card and node default settings, refer to the "Network Element Defaults" appendix in the Cisco ONS 15600 Reference Manual.
Step 1 Complete the "DLP-E26 Log into CTC" task at the node where you want to import NE defaults.
Step 2 Click the Provisioning > Defaults tabs.
Step 3 Click Import.
Step 4 Click Browse and browse to the file you are importing if the correct file name and location of the desired file do not appear in the Import Defaults from File dialog box.
Step 5 When the correct file name and location appear in the dialog box, click OK. (The correct file name is 15600-defaults.txt if you are importing the factory defaults.)
A pencil icon will appear next to any default value that will be changed as a result of importing the new defaults file.
Step 6 Click Apply.
Step 7 If the imported file fails to pass all edits, the problem field shows the first encountered problem default value that must be fixed. Change the problem default value and click Apply. Repeat until the imported file passes all edits successfully.
Step 8 If you are modifying node-level defaults, a dialog box appears telling you that applying defaults for node level attributes overrides current provisioning and asks if you want to continue. Click Yes.
If you are modifying the IIOP Listener Port setting, a dialog box appears warning you that the node will reboot and asks if you want to continue. Click Yes.
Note Changes to most node defaults reprovision the node when you click Apply. Changes made to card settings using the Defaults Editor do not change the settings for cards that are already installed or slots that are preprovisioned for cards, but rather, change only cards that are installed or preprovisioned thereafter. To change settings for installed cards or pre-provisioned slots, see Chapter 10 "Change Card Settings."
Note Changing some NE defaults can cause CTC disconnection or a reboot of the node in order for the default to take effect. Before you change a default, view the Side Effects column of the Defaults editor (right-click a column header and select Show Column > Side Effects) and be prepared for the occurrence of any side effects listed for that default.
Stop. You have completed this procedure.
NTP-E182 Export Network Element Defaults
Note The defaults currently displayed are exported whether or not they have been applied to the current node.
Note The NE defaults can also be exported from the File > Export menu. These exported defaults are for reference only and cannot be imported.
Step 1 Complete the "DLP-E26 Log into CTC" task at the node where you want to export NE defaults.
Step 2 Click the Provisioning > Defaults tabs.
Step 3 Click Export.
Step 4 If the desired file to export to does not appear in the Export Defaults to File dialog box (or does not yet exist) click Browse and browse to the directory where you want to export the data; then either choose or type in (to create) the file to export to [the defaults will be exported as a text file delimited by equals (=) signs].
Step 5 Click OK.
