Mounting a BCM main unit and expansion unit

Before you mount a BCM main unit or expansion unit, you must decide how you want to mount

the units. The main unit and expansion unit are typically mounted in the same manner. Nortel

provides three methods of mounting the BCM units:

• rack-mount

•wall-mount

• desktop-mount

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.

Refer to the chapters “Installing a main unit” and “Installing an expansion unit” in the BCM200/

400 4.0 Installation and Maintenance Guide for more detailed information.

Installing a BCM unit in a rack

To rack-mount a BCM unit (main unit or expansion unit), you need the rack-mount kit included

with the main unit.

Use the following procedures to install a BCM unit in a rack:

• “To attach the rack-mount brackets” on page 18

• “To mount a BCM unit in an equipment rack” on page 18

Caution: When installing a unit in a rack, do not stack units directly on top of one another

in the rack. Fasten each unit to the rack with the appropriate mounting brackets. Mounting

brackets cannot support multiple units.
