Connecting the cards

The data networking hardware (MSC) is installed in the BCM main unit at the factory. All systems
have dual embedded Ethernet interfaces. Some models come with an embedded V.92 modem.
WAN cards and modems are ordered separately.

Figure 79

shows a BCM200 configuration with a

field-installed WAN card.

Warning: Check with your network administrator before you connect the BCM system
to the network to ensure there are no IP address conflicts.

The default address for the BCM system is:

•

IP address:10.10.10.1

•

Subnet: 255.255.255.0

If the default IP address will create a network conflict, you must change the IP address of
the BCM system before you connect any network connections.

To change the IP address outside of a network, you can use a computer and an Ethernet
crossover cable or a terminal and a null modem cable.

Refer to

“Using the Ethernet crossover cable” on page 178

“Connecting through the

serial port” on page 179

for detailed instructions about connecting to the BCM system.

Warning: Do not plug the WAN or modem cables into the system unless it is running.

For maintenance shutdowns, refer to

“Performing a system shutdown” on page 231

Note:

Your system may not have all the cards indicated.
