Installing the BCM50 unit on the wall

To wallmount a BCM50 unit, you need a wallmount bracket. The wallmount bracket is attached to the wall, and the BCM50 unit is connected to the wallmount bracket. If the BCM50 system includes additional units, you need a wallmount bracket for each unit. Each wallmount bracket includes a cable management tray that you use to store and organize the cables connected to the BCM50 units. An optional wiring field card simplifies the cable connections for the lines and extensions.

If desired you can install an optional plywood backboard 2 cm (3/4 in.) thick.

Caution: Refer to “Checking the installation prerequisites” on page 75 for acceptable environmental conditions before selecting a location for the BCM50.

Caution: BCM50 units must be mounted side-by-side on the wall. DO NOT attempt to mount units on top of each other when using the wallmount option.

Caution: To keep the BCM50 operating at the optimal internal temperature, keep the top, sides, and rear clear of obstructions and away from the exhaust of other equipment.

Use the following procedures to install the BCM50 unit on a wall:

To install the BCM50 wallmount bracket

1Use a pencil to mark the location of the plywood backboard on the wall. Use a ruler and a level to make sure that the plywood backboard is level.

Note: Nortel recommends the use of a plywood backboard to simplify installing multiple BCM50 units. However, due to the compact size and light weight of the BCM50 units, a backboard is not required.

If you are not using a backboard, use the appropriate wall anchors or ensure the screws are in a stud.

2Mount the plywood backboard securely to the wall.

3Place the wallmount bracket on the backboard and mark the location of the center keyhole-shaped screw hole on the plywood backboard (see Figure 32 on page 85).
