Troubleshooting the 4601 IP Telephone
Because the 4601 IP Telephone lacks a display, it uses its LEDs to indicate status and error
situations. In Table 4
, the Messages shown in the first column correspond to the equivalent
conditions described in Table 3
. Rather than displaying messages, the 4601 turns its LEDs on
and off to indicate status or an error condition. LED indication is described in the second column
of this table. In addition, not all conditions result in unique LED indications.
Undefined Error CAUSE: The PBX has rejected registration for an unspecified reason.
RESOLUTION: Consult your Avaya Media Server administration and
troubleshooting documentation.
Resource Error CAUSE: The PBX rejects the registration request.
RESOLUTION: Verify administration to ensure the telephone’s proper
IP Address, extension, and password are being used.
Wrong Set Type CAUSE: The PBX does not recognize the set type.
RESOLUTION: Ensure the PBX is properly administered to expect the
appropriate telephone for the IP Address and extension.

milliseconds off for 500 milliseconds followed by 500 milliseconds off).
