1.16.2 Card Replacement
To replace an ONS 15454 card with another card of the same type, you do not need to make any changes 
to the database; remove the old card and replace it with a new card. To replace a card with a card of a 
different type, physically remove the card and replace it with the new card, then delete the original card 
from CTC. For specifics, refer to the “Maintain the Node” chapter in the Cisco ONS 15454 DWDM 
Procedure Guide.
Caution Removing any active card from the ONS 15454 can result in traffic interruption. Use caution when 
replacing cards and verify that only inactive or standby cards are being replaced. If the active card needs 
to be replaced, switch it to standby prior to removing the card from the node. For traffic switching 
procedures, refer to the Cisco ONS 15454 DWDM Procedure Guide. 
Note An improper removal (IMPROPRMVL) alarm is raised whenever a card pull (reseat) is performed, 
unless the card is deleted in CTC first. The alarm clears after the card replacement is complete.
