Action
The DHCP server offered the
wireless handset a lease that is
too short. The minimum lease
time is 10 minutes. One hour
is the minimum recommended
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no longer valid, which forces the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 should resolve itself on
the restart. If it does not, the
problem is in the DHCP server.
Download new firmware from
the Nortel site.
See "Software updates" (page
37).
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.
