Overview  _____________________________________
This manual is intended for use by network administrators.
Each telephone on the network must be assigned a unique IP address. The address can be assigned
automatically by a DHCP server, or entered manually at the phone.
Telephone operating software can be updated from a TFTP server. The update process can be initiated
manually at the phone, or set to occur daily at a preset time. Operating software is automatically updated
during power-up or reset.
Procedures for setting up DHCP and TFTP servers, and updating the phone software, are explained
below.
DHCP Server Configuration  _____________________
The DHCP server requires a scope of IP addresses that can be assigned to the phones. The scope must
be configured with the router address, vendor-specific info, and the TFTP server address.
Examples for Windows
® 2000 Server and Windows NT® Server follow.
Windows 2000 Server
Run DHCP from the Administrative Tools menu.
Add Server
You can use an existing DHCP server for assigning IP
addresses to the telephones, or add a new server.
  1.  Select Add Server from the Action menu.
  2.  Enter the IP address of the DHCP server in the
This server field.
  3. Click OK.
Add Scope
  1.  Select the DHCP server you will use for assigning IP addresses to the telephone.
  2. Select New Scope from the Action menu to run the New Scope Wizard.

  3.  Click Next to show the Scope Name screen.

  7.  If you need to exclude some IP addresses from
the range, enter them here, otherwise click Next.
  8.  You can use the defaults, or enter a new lease
duration for telephone IP addresses. Lease
duration should be set to 7 days or longer.
  9. Select Yes on the Configure IP Options screen.
When the lease expires the phone
shows a diagnostic display if idle,
while attempting to negotiate a new IP
address lease at preset intervals. If
the phone is active, the call will be
unaffected and the diagnostic display
will be shown when the call is cleared.
If the same IP address is offered by
the DHCP server, the phone returns to
operation without restarting, otherwise
the phone will restart after receiving a
new IP address.

is recommended that ICMP ping prior
address assignment be disabled at the
DHCP server.
