Several Telephones Stop Working; Identifying The Problem When Several Phones Stop Working - Avaya G350 Installing And Upgrading

Troubleshooting
6. Check the LEDs on the module to which the telephone connects. Make sure the LED for
the port to which the telephone is connected is lit. If it is not lit, the problem may be with the
port or the module. If the ALM LED is lit, this is also an indication that there is a problem
with the port or the module. Note the port and module and contact your project manager.

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 G350. If the telephones that do not work are IP
telephones connected to an MM314 or MM316 PoE module, the problem could be one of the
following:
PoE is disabled on certain ports.
●
Too many or a bad selection of PoE ports are being used.
●
The power supply to the MM314 or MM316 is not working.
●

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 connected 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 123.
3. If the affected telephones are IP telephones connected to an MM314 or MM316 media
module, check the following:
- The PoE configuration and status of the IP telephones. Use the show powerinline
CLI command to display the relevant information. Check if the affected telephones are
not be receiving power due to the PoE power status or 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.
- The power supply of the MM314 or MM316 media module.
