displays

(Continued) The Deskset cannot
locate the DHCP server or the
Deskset cannot obtain an IP
address from the DHCP server, or

Make sure that the DHCP server is still assigning IP

then the problem may lie with the DHCP server
having this much additional equipment added at one

installed your system.
Check the IP address. If the first two octets read

, then the Deskset cannot find a DHCP
server. Disconnect the device from the network and
reconnect it. Check the new IP address.
If the proceeding conditions are met but the problem
persists:

Power cycle the Deskset by unplugging the
power cord and plugging it back in.

If power cycling does not work, backup your
Deskset and reset to factory defaults by using a
paper clip to press and hold the reset switch
(located on the underside of the unit) for more
than five seconds. Restore your settings after
reboot. See
“Backup/Restore Settings” on
