If you must change the IP address (due to a conflict with your network), connect to the BCM 
system using an Ethernet crossover cable (see 

), 

through the serial port (see 

), or change the IP 

address using Telset Administration. 

You use an Ethernet crossover cable connected to a computer with a network card to connect your 
computer to the LAN card in the BCM main unit. With this connection, you can use Element 
Manager to configure the BCM system when you are unable to immediately connect your system 
to the LAN card or your system does not have a network connection.

You use this type of connection in these situations:

•

The computer you are using does not have access to the BCM system through the network.

•

The BCM system is not connected to a LAN or WAN.

•

You have to change the IP address and netmask for the BCM system before you connect it to 
the network.

To connect to the BCM system using an Ethernet crossover cable, you need a computer equipped 
with a 10/100 Base T network interface card and TCP/IP protocol.
