DHCP NACK error A NACK (Negative
ACKnowledge) was received
from the DHCP server.
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no longer valid, which forces the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.
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 may require
the wireless handset to be
returned to Nortel Networks 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 was assigned
a unique address.
Erase Failed Download process failed to
erase the memory in the
wireless handset.
Operation will retry but may
eventually report the error “int.
error: 0F”.
Power cycle the wireless
handset.
Erasing memory The wireless handset has
determined that a download
should occur and is erasing the
current software from memory.
None. When the progress bar
fills the display line, the erase
operation is complete.
