Damaged Router

If you detect physical damage to the router, report the problem to the Nortel

Networks Technical Solutions Center.

Power Problem

Troubleshoot a power problem as follows:

Make sure the power cable is firmly connected to the router and the

electrical outlet.

Make sure that the Ethernet transceivers have power.

If they do not, call the Nortel Networks Technical Solutions Center.

If the router is a BCN

or CN

, determine whether the circuit breaker

broke the power circuit.

If the router is a BCN or BLN

, check the power supply LEDs.

If a single power supply LED is off and the power supplies are modular, make

sure that all power supply cables are firmly connected. Otherwise, replace the

power supply.

If more than one power supply LED is off, remove one power supply. If all of

the remaining power supply LEDs light, replace the power supply you

removed. Otherwise, reinsert the power supply and remove another. Repeat

this procedure until you find the problem power supply.

• A power surge.

• You hot-swapped a link module that does not meet the minimum version
