Step 8 Simultaneously pivot both ejector levers

toward each other until they are parallel to

the faceplate. This secures the card to the

backplane.

Step 9 Tighten the top and bottom captive

screws. See Figure 2.

Tip Make sure that the captive screws are tight

on each newly installed card. These screws

prevent accidental removal of the card and

provide proper grounding for

electromagnetic interference (EMI)

shielding.

4 Removing the Card

To prevent the alarms from activating,

administratively shut down the card before

removing it from the chassis. Refer to “Shutting

Down and Restarting the Interface” in the

Cisco uBR10012 Software Configuration Guide.

See “Related Documentation”.

If the maintenance LED is on, you can remove the

cable interface line card without affecting system

operations.

Step 1 Make sure that you are grounded.

Step 2 Disconnect all the cables from the card.

Step 3 Unscrew the top and bottom captive

screws on the card.

Step 4 Simultaneously pivot both ejector levers

away from the card to disengage the card

from the backplane.

Step 5 Slide the card out of the slot and place it

on an antistatic surface.

Note For proper cooling and airflow, always

install a blank cable interface line card

cover in a blank line card slot.

5 Troubleshooting

1. Are all enabled LEDs on?

If yes, the system is operational.

If no, check the following possibilities.

a. If the enabled LED on a cable interface line

card is off, verify that the card has been

enabled and configured for operations.

The enabled LED remains off when a card

has not been configured and enabled.

b. If a port has been enabled but its

corresponding enabled LED is still off,

check to see if the card has pulled away

from the router. Reseat the card in its slot

(you do not have to turn off the system

power when removing or replacing a

card). After the system re-initializes the

interfaces, the enabled LED on the cable

interface line card should come on.

2. If the enabled LED remains off after the above

checks, it is likely that the system has detected

a processor hardware failure.
