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:
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.
