Using a Remote DHCP Server
Use this procedure to program an external DHCP server (for example,
Windows NT or Windows 2000 server) to support a DHCP address range.
Once programmed, IP phones and PCs will obtain IP addresses from the
external DHCP server rather than the CXi controller.
1. In Form 47 (IP Networking), Subform 02 (DHCP Server):
- Disable the internal DHCP server.
- Add the following options to the external DHCP server:

address: the L2 Switch IP of
CXi; a router on LAN; or the

6 Domain Name Server For an existing network that
already has DNS server(s),

which will resolve names in the
Internet DNS system provided
that the WAN port is enabled.
