BCM50 hardware
The following BCM50 hardware items simplify the setup and connection of the system:
• Rack-mount shelf on page 48
• Wall-mount bracket on page 49
• Power supply mounting bracket on page 50
• Patch panel on page 49
• Wiring field card on page 50
Rack-mount shelf
To rack-mount a BCM50 unit (main unit or expansion unit), you need a rack-mount shelf. The
rack-mount shelf mounts in a standard 19-inch equipment rack. The BCM50 unit then clips into
the tabs on the rack-mount shelf. These tabs prevent the unit from sliding or falling off the shelf.
If the BCM50 system includes additional units, you can clip another unit to a second set of tabs on
the rack-mount shelf. You can clip additional units to tabs on the top of the other units. See the
