Description
DHCP Error 5
y...y = DHCP Server IP

responding to renewal
attempts. At least one renewal
succeeded.
y...y = DHCP Server IP

explicitly refused renewal.
The handset software
download files are incorrect or
corrupted.

its same IP address.
Action
lease time. The wireless
handset stops trying.
Reconfigure the DHCP
server and power-cycle the
wireless handset.
Failure during WEP Key
rotation process (proprietary
failure).
The wireless handset failed
to renew its DHCP lease,
either because the DHCP
server is not running, or
because the configuration is
changed by the
administrator. The wireless
handset attempts to
negotiate a new lease or
display one of the DHCP
errors (1-5).
The DHCP lease currently in
use by the wireless handset
is no longer valid, which
forces the wireless handset
to restart. This problem
resolves itself on the restart.
If it does not, the problem is
in the DHCP server.
Download new software
from the Avaya site. See
Software updates on
page 155.
None. Do not remove the
battery or attempt to power
off the phone while this
message is displayed. Doing
so can require the wireless
handset to be returned to
Avaya to be recovered.
If using DHCP, check that the
DHCP server is properly
configured to avoid duplicate
addresses.
If using Static IP, check that
the wireless handset is
assigned a unique address.
