5 Removing the Card
To prevent the alarms from activating,
administratively shut down the card using the
shutdown command in interface configuration
mode before removing it from the chassis.
Step 1 Make sure that you are properly
grounded.
Step 2 Disconnect all the cables from the cable
interface line card.
Step 3 Unscrew the captive installation screws on
the faceplate.

Step 4 Grasp the handle and carefully pull the
card out of its slot (see Figure 4).

Caution Always handle the cable interface line
card by the carrier edges and handle;
never touch the card's components or
connector pins.
Step 5 Place the card on an antistatic surface with
the component side facing up.
Note If the card is being returned to the factory,
immediately place it in a static shielding
bag and proper packaging for protection.
Caution For proper cooling and airflow,
always install a line card cover in an
empty line card slot.
6 Troubleshooting
Check the following:
1. Make sure that the card is securely seated in
the chassis.
If the captive screws do not tighten all the way,
the card is not properly seated in the chassis or
backplane. Carefully pull the card halfway out
of the slot, reinsert it, and tighten the captive
installation screws.
Caution A partially seated line card can cause
the router to reboot.
2. Are all enabled LEDs on?
If yes, the system is operational.
If no, check the following possibilities:
a. Verify that the card has been enabled and
configured for operation. The enabled
LED remains off when a card has not been
configured and enabled.
b. If a port is enabled but its corresponding
enabled LED is still off, check to see if the
card has pulled away from the backplane.
Reseat the card in its slot. (You do not
have to turn off the system power to do
this.) After the system reinitializes the
interfaces, the enabled LED on the card
should come on.
3. If the enabled LED remains off after the above
checks, it is likely that the system has detected
a processor hardware failure.
