Troubleshooting Routers

3-2

Damaged Router

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

Networks Technical Response Center.

Power Problem

Troubleshoot a power problem as follows:

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

electrical outlet.

2. Make sure that the Ethernet transceivers have power.

If they do not, call the Bay Networks Technical Response Center.

3. If the router is a BCN

(Backbone Concentrator Node) or CN

(Concentrator Node), determine whether the circuit breaker broke the

power circuit.

4. If the router is a BCN or BLN

(Backbone Link Node), check the power

supply LEDs.

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

sure that the connection is ﬁrm. Otherwise, replace the power supply module.

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

the remaining power supply LEDs light, replace the one you removed.

Otherwise, reinsert it, and remove another. Repeat this until you ﬁnd the

problem power supply.

Blown Fuse

The following events may cause a fuse to blow:

• A power surge

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

requirements for hot-swap support.

To determine whether the link module satisﬁes hot-swap requirements, refer

to the Implementing guide shipped with the latest upgrade package or to the

“Compatibility Matrix” document from the Bay Networks bulletin board, or

contact your Bay Networks sales representative.
