Cisco Systems Cisco 12008 manual Status LEDs on an SFC

Removing and Replacing Switch Cards

Step 2 The secondary indication of SFC status is provided by two LEDs on each SFC (see Figure 7-21).

Observe each pair of LEDs on each SFC for the following indications:

•If the left LED (OK) is on (green), the SFC is operational.

•If the right LED (FAIL) is on (amber), the SFC is faulty. In this case, proceed with Step 3.

Step 3 If the new switch card is faulty, perform the following steps, as appropriate:

•Reseat the card in the slot and again observe its LEDs, as outlined in Step 1, Table 7-2, and Table 7-3.

•If the associated LEDs for the card continue to indicate that the card is faulty, replace the card with a new one and repeat the verification procedure. If this does not resolve the problem, contact your Cisco service representative for assistance.

•If you have installed new SFCs in the lower card cage and they pass the validation tests (as affirmed by the state of the primary and secondary LEDs noted in Step 1 and Table 7-3, respectively), replace the air filter assembly and secure it in place with the two captive installation screws.
