Message Description Action
wireless handset stops trying.
Reconfigure the DHCP server
and power-cycle the wireless
handset.
DHCP Error 5 Failure during WEP Key
rotation process (proprietary
failure).
DHCP Lease Exp
yyy.yyy.yyy.yyy
y...y = DHCP Server IP address
DHCP is not responding to
renewal attempts. At least one
renewal succeeded.
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).
DHCP NACK error
yyy.yyy.yyy.yyy
y...y = DHCP Server IP address
DHCP server explicitly refused
renewal.
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no longer valid, which forces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.
DL Not On Sector The handset software
download files are incorrect or
corrupted.
Download new software from
the Nortel site.
See "Updating software" (page
114).
DO NOT POWER OFF The wireless handset is in a
critical section of the software
update.
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 Nortel to be
recovered.
Duplicate IP The wireless handset has
detected another device with
its same IP address.
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.
