BCM50 Installation and Maintenance Guide
If the BCM50 system includes additional units, you can clip another unit to a second set of tabs on
the rackmount shelf. You can clip additional units to tabs on the top of the other units (see Figure
13).

Patch panel
The BCM50 patch panel simplifies the connections of lines and extensions to the main unit. The
BCM50 patch panel installs into the rackmount shelf in a standard equipment rack and connects to
the RJ-21 telephony connector using a user-supplied RJ-21 cable (see Figure 14).

Wallmount bracket
To wallmount a BCM50 unit (main unit or expansion unit), you need a wallmount bracket. The
wallmount bracket is attached to the wall, and the 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 (see Figure 15 on page 48).
