Nortel Networks BCM1000 manual Connecting when there is an IP address conflict, Pin Signal

Chapter 9 Starting the system 125

Connecting when there is an IP address conflict

If you cannot use the default IP address, you must change the IP address of the BCM1000 through one of these connections:

•a terminal and a null modem cable. Refer to “Using a null modem serial cable” on page 125.

•a computer and an Ethernet crossover cable. Refer to “Using an Ethernet crossover cable” on page 128.

After you set the initial parameters, you can connect to the Unified Manager through the network to complete the system setup using the Quick Start Wizard.

If you do not have a network connection, you can also access a Quick Start Wizard through a serial link.

For detailed information about configuring the BCM1000 using the Unified Manager, refer to the Business Communications Manager Programming Operations Guide

Using a null modem serial cable

You must use a null modem cable connection to the BCM1000 if the default IP address is not compatible with your LAN or WAN network.

Required equipment:

•null modem cable

•VT100-compatible terminal or a computer that has a terminal program such as Hyperterminal

Warning: Your terminal must be VT100-compatible and must support the VT100 National Character set. If the terminal does not support the National Character set, the text displays incorrectly.

Setting up the null modem cable

Table 33 shows the correct wiring for the BCM1000 serial port of the null modem cable.
