Refer to the following sections for information on installing an expansion unit:
• “Unpacking the expansion unit”
• “Installing the expansion unit” on page 104
• “Connecting the BCM expansion unit to the BCM main unit” on page 105
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.
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
89 .
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 94
• “Installing the main unit on the wall” on page 98
• “Installing the main unit on a flat surface” on page 100
Warning: Make sure the power supply to the expansion unit is disconnected
before inserting or removing an MBM.
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.
