•“Installing the BCM50 unit on the rackmount shelf” on page 81

•“To install the BCM50 unit on the wallmount bracket” on page 86

•“To install the BCM50 unit on a desktop or shelf” on page 89

2Rotate the power supply retention clip so that the power supply jack is clear.

3Connect the power supply cord to the main unit.

4Rotate the power supply retention clip to lock the power supply cord in place.

5Connect to ac power source:

a If the system has a UPS, connect the USB cable to the USB port on the main unit and plug the UPS power cord into the ac power source (wall outlet).

b If the system does not have a UPS, plug the power supply cable into the ac power source (wall outlet).
