BCM450 main unit LAN connection

For more information, see Nortel Business Communications Manager 450 Installation—System

(NN40170-303).

To connect a BCM450 system to the LAN

1 Connect one end of a standard Ethernet cable to your LAN.

2 Plug the other end of the Ethernet cable into the LAN port on the BCM450 main unit.

3 If you want to use the internal BCM450 network switch to connect another IP device to the

LAN, connect an Ethernet cable between the IP device and one of the additional LAN ports on

the BCM450 system.

If you wish to connect more than one device to the BCM450 main unit, you must connect a Layer

2 switch using the procedure above. After the Layer 2 device is connected, connect the devices to

the BCM450 through the Layer 2 switch.

If you cannot connect your BCM450 system to the LAN, you can access the system by connecting

through the OAM port. See To connect to the system using the OAM port on page 33.

DHCP server configuration and IP address

By default, the main unit is configured with a dynamic IP address, which means the unit requests

an IP configuration from a DHCP server.

The BCM450 main unit can have two DHCP server configurations:

• If an external DHCP server is not present on page 30

• If an external DHCP server is present on page 31

For more information, see Nortel Business Communications Manager 450 Installation—System

(NN40170-303).

If an external DHCP server is not present

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

configuration:

Warning: The DHCP server on the main unit is enabled (IP Phones only) by

default. If your network already contains a DHCP server, disable the DHCP server

on the main unit.

IP address:

192.168.2.2

Subnet mask:

255.255.254.0

Gateway:

192.168.1.1
