Chapter 13: Troubleshooting

You can have problems with phones, a trunk, the power, or the WAN. It is necessary to identify
the specific problem to figure out how it can be resolved. In addition, you may have to perform
an NVRAM initialization if you are unable to access the CLI.

One telephone stops working

If one telephone in the network stops working, but the other telephones and data devices
continue to work normally, the problem is probably with the telephone itself. There could also be
a problem with the telephone's connection to the Avaya G450 Media Gateway, or a power
management event, in which the power budget is exceeded and low priority ports are
disconnected.

Identifying the problem when one phone stops working

1. Replace the telephone. If the new telephone works, the problem is with the telephone
itself. If the new telephone does not work, go on to the next step.
2. See Maintenance Procedures for Avaya Communication Manager, Media Gateways and
Servers, 03-300432 for further information.

No power on the G450

1. Check the AC power source with a voltmeter.
2. Connect the Avaya G450 Media Gateway to a different AC power source. If the G450 has
power, the problem is with the original power source. If the G450 still does not work, go on
to the next step.
3. Check the ALM LED on the Avaya G450 Media Gateway chassis. If it is lit, there may be a
system-wide problem. Contact your project manager. See
description on page 127.
