Troubleshooting

Several telephones stop working

If some telephones in the network stop working, but others continue to work, the problem could
be with a trunk or with one of the modules in the G450.

Identifying the problem when several phones stop working

1. Determine whether all the telephones that are affected connect to the same switch or port.
If they do, the problem is probably with that switch or port. If they do not, go on to the next
step.
2. Determine whether all the telephones that are affected connect to the same module. If
they do, check the LEDs on that module. If the ALM LED is lit, there may be a problem with
the module. Contact your project manager. If not, go on to the next step. For information
on the various modules and their LEDs, see
page 131.
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. For information on the chassis, see
Appendix A: Front panel description

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

A trunk stops working

1. Check the connection between the trunk and the Avaya G450 Media Gateway. If the
physical connection is loose, tighten the connection. If the trunk still does not work, go on
to the next step.
