•one power supply cable

•one power supply retention clip

•four rubber feet

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 rackmount a BCM50 unit, you need the optional rackmount 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 rackmount shelf. These tabs prevent the unit from sliding around or falling off the shelf. If the BCM50 system includes additional units, another unit can be mounted to a second set of tabs on the rackmount shelf. Any additional units can be mounted 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 known as 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: Refer to “Checking the installation prerequisites” on page 75 for acceptable environmental conditions before selecting a location for the BCM50 system.
