Removing and Replacing the Cable Management System
Cisco 12008 Gigabit Switch Router Installation and Configuration Guide 7-68
In Step 2 above, since the SFCs are not visible during normal operation, you must remove
the air filter assembly from the router to observe the status LEDs on each SFC (see
Figure 7-21). These LEDs are arranged side-by-side behind a raised tab near the middle of
the card (as you view the SFC from the front of the router).
Alternatively, you could issue the following command at the privileged EXEC mode
prompt to show the status of all the router’s LEDs:
router# show environment leds
If the CSC indicates a fault with an SFC, you must still remove the air filter assembly from
the switch router and observe the status LEDs on the SFCs themselves to determine which
card is at fault.
Removing and Replacing the Cable Management System
This section presents procedures for removing and installing a cable-management tray or a
cable-management bracket for the Cisco 12008.
To perform these procedures, you will need the following tools:
•
1/4-inch flat-blade screwdriver
•
Number 1 Phillips screwdriver
•
ESD-preventive wrist strap
•
ACS-GSR8-CCBLM(=)—Cable-management tray
•
ACS-GSR-LCCBLM(=)—Cable-management bracket
Removing a Cable-Management Tray
The cable-management tray (ACS-GSR8-CCBLM) is actually three pieces: end cap, top
trim, and tray (see Figure 7-22).
