ENABLED LED on the line cards or on

the uplink cards does not go on.

1. If the ENABLED LED is off, first verify that the card has been enabled and

ENABLED LED remains off when a card has not been configured and enabled.

2. If a port has been enabled but its corresponding ENABLED LED is still off,

reseat the card in its slot (you do not have to turn off the system power when

removing or replacing the card). After the system re initializes the interfaces,

the ENABLED LED on the card should go on.

3. If the ENABLED LED remains off after the above checks, it is likely that the

system has detected a processor hardware failure. See the “Obtaining Technical

Assistance” section on page 41.
