5Removing 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.

6Troubleshooting

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.
