Chapter 12: Troubleshooting

You can have problems with phones, a trunk, the power or the WAN line. 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 G350 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. Connect the telephone to a different power supply. If the telephone works, the problem is
with the original power supply. If the telephone still does not work, go on to the next step.
3. Connect the telephone to a different network port. If the telephone works, the problem is
with the original network port. If the telephone still does not work, go on to the next step.
4. Check the module on the Avaya G350 Media Gateway to which the telephone is
connected. Check whether the physical connection is loose, and tighten the connection if
necessary. If the telephone still does not work, go on to the next step.
5. If the telephone is connected to a PoE port on an MM314 or MM316 media module and
does not have its own power supply, plug in a power supply and see if the telephone
works. If it works, the problem is with the PoE configuration or power allocation. Use the
show powerinline CLI command to display the relevant information. PoE may have
been disabled on the port to which the telephone is connected, of the telephone may not
be receiving power due to the priority level configured on the port, or due to the overall
PoE power budget being exceeded. For information about PoE configuration, see
Administration for the Avaya G250 and Avaya G350 Media Gateways, 03-300436.
