Chapter 12 Add and Remove Cards and Nodes
NTP-G107 Remove and Replace DWDM Cards
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 Troubleshooting Guide or the Cisco ONS 15454 SDH Troubleshooting Guide.
Step 1 Complete the “DLP-G46 Log into CTC” task on page 2-25.
Note If you cannot log into Cisco Transport Controller (CTC) and you need to remove a card, remove
the card as described in Step 5. After you log into CTC, troubleshoot the mismatched equipment
alarm (MEA) with the Cisco ONS 15454 Troubleshooting Guide or the Cisco ONS 15454 SDH
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 on page 8-28
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 Troubleshooting Guide or the
Cisco ONS 15454 SDH Troubleshooting Guide for procedures.
Step 3 Complete the following tasks, as needed:
• If the card carries unprotected circuits, you must delete them. Complete the “DLP-G106 Delete
Optical Channel Network Connections” task on page 7-12.
• 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 on page 10-35 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 on page 10-37 to prevent traffic from switching to the TXP or MXP that you
will remove.
• If the card is an OSCM or OSC-CSM that is used as a node timing reference, complete the
“NTP-G112 Change the Node Timing Reference” procedure on page 13-17.
• If the card is an OSCM or OSC-CSM with an optical service channel (OSC) or generic
communications channel (GCC) termination, complete the “NTP-G85 Modify or Delete OSC
Terminations, GCC Terminations, and Provisionable Patchcords” procedure on page 10-39.
Note If you delete a card in CTC but do not remove it from the shelf, it will reboot and reappear in
CTC.
Step 4 Complete the “DLP-G254 Place OPT-BST and OPT-PRE Ports Out of Service” task on page 12-3.
Step 5 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 6 Insert the new card using one of the following procedures as applicable:
• NTP-G30 Install the DWDM Cards, page 3-39
• NTP-G32 Install the Transponder and Muxponder Cards, page 3-43
