Warning: Check with your network administrator before you connect the Business
Communications Manager to the network to ensure there are no IP address conflicts.
The default address for the Business Communications Manager system:
• IP: 10.10.10.1
• Subnet: 255.255.255.0
Warning: If the default IP address would create a network conflict, you must change the
IP address of the Business Communications Manager before you connect any network
connections.
To change the IP address outside of a network, you can use one of the following:
• a terminal and a null modem cable
• a computer and an ethernet crossover cable
Refer to “Use of a null modem serial cable” on page 137 or “Ethernet crossover cable
usage” on page 140 for detailed instructions about connecting to the Business
Communications Manager.
