Cisco Systems Cisco 12008 Status LEDs for the CSC State Description, Status LEDs for the SFCs

Removing and Replacing Switch Cards

To verify that a new switch card is operating properly, perform the following steps:

Step 1 Observe the LEDs on the faceplate of the CSC(s), as follows:

•For a new CSC—Observe the two status LEDs for the CSC (refer to Figure 7-20). If the bottom (ENABLED) LED is on (green), the new CSC is operational. If the top (FAIL) LED is on (amber), the new CSC is faulty (see Table 7-2). In this case, proceed to Step 3.

Table 7-2	Status LEDs for the CSC
Status LEDs		State	Description
Top LED (FAIL)		On (amber)	Indicates that the CSC is faulty
Bottom LED (ENABLED)		On (green)	Indicates that the CSC is operational

•For a new SFC—The first (primary) indication of SFC status is provided by the status LEDs for the SFCs located at the bottom of the CSC faceplate (see Figure 7-20).

If the bottom (ENABLED) LED is on (green), the installed SFCs are operational (see Table 7-3). This ends the validation procedure, except for returning the air filter assembly to its proper place (see Step 3).

If the top (FAIL) LED is on (amber), one or more of the installed SFCs is faulty (see Table 7-3). In this case, proceed with Step 2.

Table 7-3	Status LEDs for the SFCs
Status LEDs		State	Description
Top LED (FAIL)		On (amber)	Indicates that a fault has been detected in one or
			more of the SFCs.
Bottom LED (ENABLED		On (green)	Indicates that the SFCs are installed and
			operating normally.
Both LEDs		Off	Indicates that no SFCs are installed in the router.
