Chapter 7: Troubleshooting

Resolving error conditions

About this task
Installers can troubleshoot problems before seeking assistance from the system or LAN
administrator in four areas:
Procedure
1. Check both the power and Ethernet wiring for the following conditions:
• Check whether all components are plugged in correctly.
• Check LAN connectivity in both directions to all servers - DHCP, HTTP, HTTPS,
DEFINITY
• If the deskphone is powered from the LAN, ensure that the LAN is properly administered
and is compliant with IEEE 802.3af.
2. If you use static addressing:
• Use the VIEW option to find the names of the files being used and verify that these
filenames match those on the HTTP/HTTPS server. Check the Avaya Support site at
www.support.avaya.com
• Use the ADDR option to verify IP addresses.
3. If the deskphone is not communicating with the system, DHCP, HTTP, or Avaya Media
Server, make a note of the last message displayed.
Consult the system administrator. Sometimes, you can correct problems relating to
Communication Manager and HTTP communications by setting the HTTPPORT value to
81.
4. If you want the deskphone to be IEEE-powered, verify with the LAN administrator that
IEEE power is indeed supported on the LAN.

Failure to hear DTMF tones

As H.323 telephones do not send DTMF tones to non-H.323 telephones, the user need not
perform troubleshooting for failure to hear DTMF tones from a IP phone. The TN2302AP board
does not pass in-band DTMF tones.
