• one main unit (either BCM50, BCM50a, BCM50e, BCM50b, BCM50ba, or BCM50be)

• one power supply

• one power supply cable

• one power supply retention clip

• four rubber feet

• one screw to secure the RJ-21 telephony connector

• one cable tie

• a documentation CD

• the BCM50 Installation Checklist and Quick Start Guide

Visually inspect the components for damage during shipping.

If you find damage, contact your Nortel sales representative.

Installing the BCM50 unit in an equipment rack

You can install a BCM50 main unit in a standard 19-inch equipment rack along with your other networking and telecommunications equipment.

To rack-mount a BCM50 unit, you need the optional rack-mount kit (NT9T6325). This kit provides the parts to mount up to four BCM50 units into a standard 19-inch equipment rack. The

BCM50 unit mounts into the tabs on the rack-mount shelf. These tabs prevent the unit from sliding around or falling off the shelf. If the BCM50 system includes additional units, you can mount another unit onto a second set of tabs on the rack-mount shelf. You can mount any additional units to tabs on the top of the other units.

If you need to better secure a BCM50 unit, use the screws provided (four per unit) to screw the

BCM50 to the rack. This is a “hardened” installation. For a hardened installation, install only two units per rack—do not stack the units.

You can also use the optional patch panel to simplify the connections to the BCM50 RJ-21 telephony connector.

Caution: For acceptable environmental conditions before selecting a location for the

BCM50 system, see Checking the installation prerequisites on page 79.

BCM50 Installation and Maintenance Guide

88 Chapter 7 Installing the main unit

Installing the BCM50 unit on the wall

To wall-mount a BCM50 unit, you need a wall-mount bracket. The wall-mount bracket attaches to the wall, and the BCM50 unit connects to the wall-mount bracket. If the BCM50 system includes additional units, you need a wall-mount bracket for each unit. Each wall-mount 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: For acceptable environmental conditions before selecting a location for the

BCM50, see Checking the installation prerequisites on page 79.

Caution: You must mount BCM50 units side-by-side on the wall. DO NOT attempt to mount units on top of each other when using the wall-mount 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 wall-mount bracket on page 88

•

To install the BCM50 unit on the wall-mount bracket on page 90

To install the BCM50 wall-mount bracket

1 Use 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 do not use a backboard, use the appropriate wall anchors or ensure the screws are in a stud.

2 Mount the plywood backboard securely to the wall.

3 Place the wall-mount bracket on the backboard and mark the location of the center keyhole-shaped screw hole on the plywood backboard. See the figure

Wall-mount bracket on page 89.

Attach the wall-mount bracket with 5 screws:

• Two screws mount through the cable trough

(open the cable-management door).

• Three screws mount as shown in the figure.

Note : When you use three screws, Nortel recommends installing the screws in the three holes labeled “1” or the three holes labeled “2”.

4 Prepare the wall-mount bracket by removing the alignment tabs:

• If this is the only unit in the BCM50 system, remove the alignment tabs on the right side of the wall-mount bracket.

• If this is the last unit on a BCM50 system with multiple units, remove the alignment tabs on the left side of the wall-mount bracket.

Place the additional wall-mount bracket on the backboard on the right side of the existing wall-mount bracket. Use the alignment tabs to ensure the two wall-mount brackets are properly aligned.

If these options do not meet your requirements, other options are available. For example, you can route the Amphenol connector cable to the left of the unit, or you can route the cable straight down the wall.

5 Attach the wall-mount bracket with five #8 x 2 cm (#8 x 0.75 in.) round-head wood screws: a Install one screw in the backboard. Do not tighten the screw head against the backboard.

Leave approximately 0.5 cm (0.25 in.) of the screw exposed from the backboard.

b Hang the wall-mount bracket on the mounting screw.

c Use a level to make sure the wall-mount bracket is level.

d Install two screws into the screw holes in the wall-mount bracket. See the figure
