Removing and Installing Switch Fabric Cards
Verifying the Installation
To verify that the new CSC or SFC is working properly, follow these steps:
Step 1 Check the following components to make sure they are secure:
• The cards in the switch fabric card cage are fully seated in their slots, and the card ejector levers are
flush with the front edge of the card carriers.
• The air filter door is up and seated in the switch fabric card cage opening, and the four captive screws
are tightened.
Step 2 Observe the five pairs of switch fabric status LEDs on the alarm cards (leftmost slot in the upper card
cage; rightmost slot in the lower card cage). Both alarm cards should display the same LED status:
• The green LED labeled ENABLED for each installed CSC and SFC should be on.
If one of the green LEDs is off, either the corresponding slot in the switch fabric card cage is empty,
or the card in that slot has not been installed correctly. Try reseating the card in the backplane
connector.
• The yellow LED labeled FAIL for each installed CSC and SFC should be off.
If one of the yellow LEDs is on, the system has detected a fault in the card installed in the
corresponding slot. The card might not be installed completely or could have an internal fault. Try
reseating the card in its slot. If that does not resolve the problem, contact your Cisco service
representative for assistance.
