Chapter 4: Troubleshooting Guidelines


This chapter describes problems that might occur during installation of the 4600 Series IP Telephones and possible ways of resolving these problems. For problems that occur during normal operation, see “Troubleshooting Guidelines” in the4600 Series IP Telephone LAN Administrator Guide.

This chapter contains the following sections:

Descriptions of error conditions and methods for resolving them.

The use of the V I E W option to view system values.

Error and status messages, and methods for resolving them.

Error Conditions

There are four areas where installers can troubleshoot problems before seeking assistance from the system or LAN administrator:

1.Check both the power and Ethernet wiring for the following conditions:

Whether all components are plugged in correctly.

Check LAN connectivity in both directions to all servers - DHCP, TFTP, HTTP, DEFINITY® /MultiVantage™.

If the telephone is supposed to be powered from the LAN, ensure that the LAN is properly administered and is compliant with IEEE 803.3af.

Ensure that the Ethernet complies with Category 5e wiring.

2.If you are using static addressing:

Use the View command) to find the names of the files being used and verify that these filenames match those on the TFTP or HTTP server. SeeThe View Administrative Option on page 65 for more information. Check the Avaya Web site to verify whether the correct files are being used.

Troubleshooting Guidelines

Use the ADDR option to verify IP addresses. SeeStatic Addressing Installation on page 39 for information.

Use the QoS option to verify QoS parameters. SeeChapter 3: Local Administrative Options.

3.If the 4600 Series IP Telephone is not communicating with the system (DHCP, TFTP, HTTP or Avaya Media Server), make a note of the last message displayed. Consult the system administrator.

4.If you expect the telephone to be IEEE-powered,verify with the LAN administrator that IEEE power is indeed supported on the LAN.


Because the 4601 IP Telephone does not have a display, it is limited in its ability to provide visual feedback and error messages. See Troubleshooting the 4601 IP Telephone later in this chapter for more information.

DTMF Tones

The failure to hear DTMF tones sent by a far-end4600 Series IP Telephone does not require any action on the user’s part. The TN2302AP board does not passin-bandDTMF tones.

Power Interruption

If power to a 4600 Series IP Telephone is interrupted while the telephone is saving the application file, the TFTP application can stop responding. If this occurs, restart the TFTP server.
