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.

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 G250 Media Gateway.

Identifying the problem when one telephone 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 G250 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 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 the G350
Gateways, 03-300436.
