Chapter 6: Server Administration

Software prerequisites

Ensure that you own licenses to use the DHCP, HTTP, and HTTPS server software.
Note:
You can install the DHCP and the HTTP server software on the same computer.
Caution:
The firmware in the 9600 Series IP Deskphones reserves the IP addresses of the form
192.168.2.x for internal communications. The phone might not function properly if you configure
addresses in that range.

Administering the DHCP and file servers

Dynamic Host Configuration Protocol (DHCP) minimizes maintenance for the 9600 Series IP
Telephone network. With DHCP, you need not individually assign and maintain IP addresses and
the other parameters on each IP phone on the network.
Depending on administration, the DHCP server provides the following information to the 9600 Series
IP Telephones:
• An IP address of the 9600 Series IP Telephone
• An IP address of the Avaya call server
• An IP address of the HTTP or HTTPS file server
• The subnet mask
• An IP address of the router
• A DNS Server IP address
Administer the LAN so each 9600 Series IP deskphone can reach a DHCP server that contains the
IP addresses and subnet mask.
The 9600 Series IP Telephone cannot function without an IP address. Using the IP address reuse
capability, the phone can reuse the previous IP address and parameter settings even if the DHCP
server is temporarily unavailable. A user can manually assign a different IP address to an IP
deskphone. When the DHCP server finally returns, the 9600 Series IP Telephone does not search
