Chapter 5: 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
®
/MultiVantage
™
.
• 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. For more
information, see Using the VIEW craft procedure for troubleshooting on
page 72. Check the Avaya Support site at www.support.avaya.com to verify
whether the correct files are being used.
• Use the ADDR option to verify IP addresses. For more information, see
Changing IP address information on page 47.
3. If the deskphone is not communicating with the system, DHCP, HTTP, or Avaya
Media Server, make a note of the last message displayed. For more information,
see Installation error and status messages on page 76 and Operational errors
and status messages on page 81.
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.
