102Chapter 7 Installing an expansion unit

Refer to the following sections for information on installing an expansion unit:

•“Unpacking the expansion unit”

•“Installing the expansion unit” on page 102

•“Connecting the BCM expansion unit to the BCM main unit” on page 103

Unpacking the expansion unit

Open the expansion unit box and remove all the components. Check that you have the following components:

•one BCM expansion unit

•one power supply cable

•one expansion cable (shielded Ethernet cable)

•four rubber feet

Visually inspect the components for any damage that may have occurred during shipping. If you find any damage, contact your Nortel representative.

Warning: Make sure the power supply to the expansion unit is disconnected before inserting or removing an MBM.

Installing the expansion unit

This section describes how to install the BCM expansion unit.

Make sure that the expansion unit is installed close enough to the main unit so that the supplied 5 m (16 ft) expansion cable can be connected between the expansion unit and main unit. The expansion unit has the same environmental and electrical requirements as the main unit. For more information about these requirements, refer to “Checking the installation prerequisites” on page 87.

The expansion unit can be mounted in a rack, on a wall, or on a desktop. Typically, the expansion unit is mounted in the same way as the main unit.

The expansion unit is similar in design to the main unit, therefore, it is installed in the same manner as the main unit. Refer to the following sections for procedures on mounting an expansion unit:

•“Installing the main unit in an equipment rack” on page 92

•“Installing the main unit on the wall” on page 96

•“Installing the main unit on a flat surface” on page 98

Caution: When installing the BCM expansion unit in a rack, do not stack units directly on top of one another. Fasten each unit to the rack with the separate mounting brackets.
