156Chapter 9 Connecting the cables

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 or “Connecting through the serial port” on page 179 for detailed instructions about connecting to the BCM system.

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: 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).
