No power on the G350

1. Check the AC power source with a voltmeter.
2. Connect the Avaya G350 Media Gateway to a different AC power source. If the G350 has
power, the problem is with the original power source. If the G350 still does not work, go on
to the next step.
3. Check the ALM LED on the Avaya G350 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 G350 Media Gateway. If the
physical connection is loose, tighten the connection. If the trunk still does not work, go on
to the next step.
2. Check the ALM LED on the module to which the trunk connects. If it is lit, see Maintenance
Alarms for Communication Manager 2.1, Media Gateways and Servers, 03-300190 for
testing procedures.

A WAN line stops working

1. Check the connection between the WAN line and the Avaya G350 Media Gateway. If the
physical connection is loose, tighten the connection. If the line still does not work, go on to
the next step.
2. Check the ALM LED on the module to which the WAN line connects. If the ALM LED is lit,
the problem may be the configuration of the module or a lack of T1 signal. You can try the
following:
- For E1/T1 interfaces, use the show controllers command to view the status of the
interface's controller. Make sure the controller is up, and that all error counters do not
increase.
