DHCP and IP addressing
Each main unit includes a dynamic host configuration protocol (DHCP) server.
This DHCP server supplies Nortel IP Phones and client computers with IP
addresses and connection information.
You can configure the DHCP server using Element Manager.
When the DHCP client is enabled, the main unit receives IP configuration from
a DHCP server.
External DHCP server not available
If no external DHCP server is available, the main unit uses the following
default IP configuration:
IP address: 192.168.2.2
Subnet mask: 255.255.254.0
Gateway: 192.168.1.1
The DHCP server on the main unit supplies IP configuration information for all
IP devices (PCs and IP Phones). The DHCP server also supplies specific
connection information to the IP Phones.
External DHCP server available
If an external DHCP is present, the BCM450 system uses the IP configuration
supplied by the external DHCP server.
