Make sure that both ends of the cable are firmly connected to the proper

interfaces.

Check the LEDs on the rear panel of the router.

The green transceiver light comes on when the cable is secure.

If you hot-swapped a link module or reset the slot, the associated red fail LED

remains on until you run diagnostics on that slot. This condition does not

necessarily indicate a problem. However, if you run diagnostics on a slot and

the red fail LED remains on for more than a few minutes, call the Nortel

Networks Technical Solutions Center.

If the state of the connector is down, replace the cable.

Determine whether the problem is with the cable or the port by replacing the

cable with a cable that you know is good.

Perform local and remote loopback tests during network downtime, or on

ports that are not in use.

You can also loop back PPP lines; however, if you configured them with a

password, you must configure them in promiscuous mode first.

If you are accessing a DTE/DCE line with promiscuous mode off, the port

will not increment the reception statistics.

Note: Do not use the connector position in one link module to determine the

position of another. Interface 1 of one type of link module may be on the left

side, and interface 1 of another type may be on the right side. Verify the

connection by looking at the connector number on the link module.

Caution: Connect only cables that support hot-swap to connectors that

support hot-swap. Also, connect only cables that do not support hot-swap to

connectors that do not. Otherwise, damage to the board may occur.

Caution: Do not do loopback testing during network production time if the

bridge is operating on the port.
