Determining DHCP server configuration and IP address

Each main unit has a DHCP server. This DHCP server supplies Nortel IP Phones and client computers with IP addresses and connection information.

If the main unit does not have an integrated router, then the DHCP server can be configured using Element Manager.

If the main unit has an integrated router, then the DHCP server on the main unit is disabled and the DHCP server is configured using the Router Configuration page.

For more information on configuring the DHCP server, refer to “To configure DHCP server settings” on page 138.

The BCM50 system can have a main unit with or without an integrated router:

•“BCM50 main unit (no integrated router)”

•“BCM50a or BCM50e (with integrated router)” on page 68

BCM50 main unit (no integrated router)

By default, the main unit is configured with a dynamic IP address, which means it requests an IP configuration from a DHCP server.

The BCM50 main unit can have two DHCP server configurations:

•“If an external DHCP server is not present”

•“If an external DHCP server is present” on page 68

If an external DHCP server is not present

If an external DHCP server is not present, then the main unit uses the following default IP configuration:

IP address:	192.168.1.2
Subnet mask:	255.255.255.0
Gateway:	192.168.1.1

The DHCP server on the main unit supplies IP configuration information for all IP devices (PCs and IP Phones). It also supplies specific connection information to the IP Phones.
