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
