Caution Removing and replacing cards can be traffic affecting.


Caution Do not use this procedure to replace a TCC2 or TCC2P card. To replace a TCC2/TCC2P card, refer to the Cisco ONS 15454 DWDM Troubleshooting Guide.


Step 1 Complete the "DLP-G46 Log into CTC" task.


Note If you cannot log into Cisco Transport Controller (CTC) and you need to remove a card, remove the card as described in Step 6. After you log into CTC, troubleshoot the mismatched equipment alarm (MEA) with the Cisco ONS 15454 DWDM Troubleshooting Guide.


Step 2 Click the Alarms tab.

a. Verify that the alarm filter is not on. See the "DLP-G128 Disable Alarm Filtering" task as necessary.

b. Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve them before continuing. Refer to the Cisco ONS 15454 DWDM Troubleshooting Guide for procedures.

Step 3 If you are removing and replacing a card, go to Step 5.

Step 4 If you are permanently removing a card, go to Step 11.

Step 5 To remove and replace a card, complete the following tasks, as needed:

The circuits traversing through the card that needs to be replaced (for example, an amplifier) need to be protection switched. For instance, if the card you want to replace is an active transponder (TXP) or muxponder (MXP) in a Y-cable protection group, complete the "DLP-G179 Apply a Force Y-Cable or Splitter Protection Switch" task to force traffic away from the TXP or MXP that you will remove. If the card you want to replace is the standby TXP or MXP in a Y-cable protection group, complete the "DLP-G182 Apply a Lockout" task to prevent traffic from switching to the TXP or MXP that you will remove. See the Cisco ONS 15454 Procedure Guide or the Cisco ONS 15454 SDH Procedure Guide for other types of protection switching (path protection, BLSR, optical, and electrical).

If the card is used as a node timing reference, complete the "NTP-G112 Change the Node Timing Reference" procedure to change the timing reference to a card that will not be removed.

If the card is an OSCM or OSC-CSM with an optical service channel (OSC) or any TXP, MXP with generic communications channel (GCC) termination, complete the "NTP-G85 Modify or Delete OSC Terminations, DCC/GCC Terminations, and Provisionable Patchcords" procedure to delete the termination and recreate it on a card that will not be removed.


Note If you delete a card in CTC but do not remove it from the shelf, it will reboot and reappear in CTC. .


Step 6 Physically remove the card:

a. Disconnect any cables.

b. Open the card latches/ejectors.

c. Use the latches/ejectors to pull the card forward and away from the shelf.

Step 7 Insert the new card using one of the following procedures as applicable:

G30 Install the DWDM Cards

G32 Install the Transponder and Muxponder Cards

Step 8 Continue with the "NTP-G34 Install Fiber-Optic Cables on DWDM Cards and DCUs" procedure.

Step 9 Complete the following tasks or procedures, as needed:

If you switched a Y-cable protection group in Step 5, complete the "DLP-G180 Clear a Manual or Force Y-Cable or Splitter Protection Switch" task.

If you switched the timing reference in Step 5, complete the "NTP-G112 Change the Node Timing Reference" procedure to change the reference back to the new card.

If you deleted an OSC or GCC termination in Step 5, complete the "NTP-G38 Provision OSC Terminations" procedure or the "DLP-G76 Provision DCC/GCC Terminations" task.

Step 10 Go to Step 13.

Step 11 To permanently remove a card, complete the following tasks:

Delete the circuits associated with the card being removed. Complete the "DLP-G106 Delete Optical Channel Network Connections" task, and the "DLP-G347 Delete Optical Channel Client Connections" task as needed.

Physically remove the card:

Disconnect any cables.

Open the card latches/ejectors.

Use the latches/ejectors to pull the card forward and away from the shelf.

Step 12 If the card you are removing is an OSCM, OSC-CSM, DWDM Amplifier, or Filter card, complete the following tasks; otherwise, go to Step 13.

Reconfigure the circuits (OCHCC, OCHNC, Trails) as needed. Complete the "DLP-G105 Provision Optical Channel Network Connections" task task on page 7-22, and the "DLP-G346 Provision Optical Channel Client Connections" task as needed.

Reload ANS provisioning. Complete the "NTP-G143 Import the Cisco MetroPlanner NE Update Configuration File" task task on page 3-42.

Relaunch ANS. Complete the "NTP-G37 Run Automatic Node Setup" task.

Step 13 Click the Alarms tab.

a. Verify that the alarm filter is not on. See the "DLP-G128 Disable Alarm Filtering" task as necessary.

b. Verify that no unexplained alarms appear on the network. If alarms appear, investigate and resolve them. Refer to the Cisco ONS 15454 DWDM Troubleshooting Guide for procedures.

Note You cannot delete a node controller shelf from a multishelf node configuration.



Step 1 Complete the "DLP-G46 Log into CTC" task at the multishelf DWDM node where you want to delete a shelf or rack. If you want to delete a shelf, continue with Step 2. If you want to delete a rack only, go to Step 9.

Step 2 Complete the following tasks, as needed:

If cards on the shelf carry unprotected circuits, you must delete the circuits. Complete the "DLP-G106 Delete Optical Channel Network Connections" task and/or the "DLP-G347 Delete Optical Channel Client Connections" task.

If cards use internal patchcords, complete the "DLP-G355 Delete an Internal Patchcord" task.

If OSCM or OSC-CSM cards with OSC or GCC terminations are on the shelf, complete the "NTP-G85 Modify or Delete OSC Terminations, DCC/GCC Terminations, and Provisionable Patchcords" procedure to delete the terminations.

Put all ports in the Out-of-Service and Management, Disabled (OOS-MA,DSBLD) (ANSI) or Locked-enabled,disabled (ETSI) service state. For more information, see Chapter 11 "Change DWDM Card Settings."


Note It is not necessary to delete the cards from the shelf before deleting a shelf.


Step 3 From the View menu, choose Go to Parent View to return to multishelf view.

Step 4 Right-click on the subtending shelf you want to delete and choose Delete Shelf.

Step 5 In the confirmation dialog box, click Yes.

Step 6 To return the deleted shelf to a single-shelf node, you must use the LCD panel:

a. Repeatedly press the Status button until Shelf Status appears.

b. Repeatedly press the Port button until Controller Status=MS Config appears.

c. Press Status again and press Port to set multishelf mode to MS=N.

d. Press Status to choose Done.

e. Repeatedly press Status until "Save and Reboot?" appears, and then press Slot to choose Apply. This reboots the shelf. A "Saving changes; TCC may reboot" message appears on the LCD.

Step 7 After the TCC2/TCC2P reboot is complete, complete the following steps to disconnect the removed subtending shelf from the patch panel or Catalyst 2950:

a. Remove the cross-over (CAT 5) LAN cable from the RJ-45 front panel port of the TCC2/TCC2P card in Slot 7.

b. Remove the cross-over (CAT 5) LAN cable from the RJ-45 front panel port of the TCC2/TCC2P card in Slot 11.

Step 8 Reconnect the shelf to the LAN through either the backplane or one of the RJ-45 front panel ports of the TCC2/TCC2P cards. For more information, see Chapter 2 "Connect the PC and Log into the GUI."

Step 9 To delete an empty rack from the CTC window, right-click in the gray area on the rack graphic and choose Delete Rack.

Stop. You have completed this procedure.
