Chapter 4
Determining DHCP server configuration and
IP address
Each main unit has a
dynamic host configuration protocol (
DHCP) server. This DHCP server
supplies Nortel IP Phones and client computers with IP addresses and connection information.
If the main unit has no integrated router, then you can configure the DHCP server using Element
Manager.
If the main unit has an integrated router, then the DHCP server on the main unit is disabled and the
you can configure the DHCP server using the Router Configuration page.
For more information about configuring the DHCP server, see the procedure To configure DHCP
server settings on page 140.
The BCM50 system can have a main unit with or without an integrated router:
• BCM50 and BCM50b main units (no integrated router) on page 69
• BCM50a, BCM50ba, BCM50e, and BCM50be main units (with integrated router) on page 70
BCM50 and BCM50b main units (no integrated router)
By default, the main unit is configured with a dynamic IP address, which means the IP
configuration is received from a DHCP server.
The BCM50 and BCM50b main units can have two DHCP server configurations:
• If an external DHCP server is not present on page 69
• If an external DHCP server is present on page 70
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). The DHCP server also supplies specific connection information to the IP Phones.
IP address: 192.168.1.2
Subnet mask: 255.255.255.0
