88 4600 Series IP Telephone Installation Guide
Error and Status Messages
Note:
Note: This section describes error and status messages only for those IP telephones
having a display. For error and status messages related to installing a 4601 IP
Telephone, see Troubleshooting the 4601 IP Telephone
on page 92.
The 4600 Series IP Telephones issue messages in English only. The IP telephones also display
messages from the switch, which can issue messages in the local language outside the United
States.
Most of the messages in Table 3
display only for about 30 seconds, and then the telephone
resets. The most common exception is Extension in Use, which requires manual
intervention.
Table 3: Possible Error and Status Messages During Installation of 4600 Series IP
Telephones
Message Cause/Resolution
802.1X Failure CAUSE: Incorrect credentials provided for authentication or not
provided at all.
RESOLUTION: Follow the display prompts and reenter the 802.1X ID
and password.
Bad Router CAUSE: The telephone cannot find a router based on the information in
the DHCP file for GIPADD.
RESOLUTION: Change administration on DHCP, as indicated in the
4600 Series IP Telephone LAN Administrator Guide.
Checksum error CAUSE: Downloaded application file was not downloaded or saved
correctly.
RESOLUTION: The telephone automatically resets and attempts to
re-initialize.
DHCP: CONFLICT
* to program
CAUSE: At least one of the IP Address offered by the DHCP server
conflicts with another address.
RESOLUTION: Review DHCP server administration to identify duplicate
IP Address(es).
Discover
aaa.bbb.ccc.ddd
CAUSE: The 46xx telephone is attempting to discover (and register
with) the gatekeeper at IP Address aaa.bbb.ccc.ddd.
RESOLUTION: If this message appears for more than a few seconds,
especially if the IP Address keeps changing, the telephone is unable to
contact the gatekeeper. Have the LAN Administrator verify network
connectivity between the telephone and the gatekeeper. Alternately,
revise the gatekeeper addresses in the DHCP/TFTP files in accordance
with the 4600 Series IP Telephone LAN Administrator Guide to point to
different gatekeepers.
