9 If you want to change the IP addressing, enter 2 (System Configuration) and follow the
prompts.
10 If you want to configure the system through the serial port, enter 3 (Configuration Wizard).
This wizard also allows you to change the IP addressing information.
This Wizard has the same information as the Quick Start Wizard that you access through the
Unified Manager, but in a slightly different format. Refer to the Business Communications
Manager 3.0 Programming Operations Guide for a detailed description of the fields that occur
in the Configuration Wizard.
Ethernet crossover cable usage
You use an ethernet crossover cable connected to a computer with a network card to connect your
computer to the LAN card in the Business Communications Manager. With this connection, you
can run Business Communications Manager Unified Manager to configure the Business
Communications Manager system when you are unable to immediately connect your system to the
live 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 Business Communications Manager
system through the network
• the Business Communications Manager is not connected to a LAN or WAN
• you have to change the IP address and netmask for the Business Communications Manager
system before you connect it to the network
Set the crossover connections
To connect to the Business Communications Manager using an Ethernet crossover cable, you need
a computer equipped with a 10/100 Base T network interface card and TCP/IP protocol. Figure 77
shows the connections required.
Note: When you change IP address, Region, Template and/or Start DN, the system
prompts you for a restart after you accept the changes.
After the system restarts, you can continue with your system configuration.
Warning: Changing this information on an existing system completely erases the
telephony programming and disables the telephony system. It also reboots the Business
Communications Manager and expansion unit.
