Connecting a UPS to your BCM450 system
To obtain USB communication between an APC UPS and BCM450 a USB
hub is not required. APC (American Power Conversion) is the only supported
UPS vendor for BCM.
Prerequisites
• For the UPS to function correctly, you must connect it before you power
up the BCM450 system. If you connect a UPS to a running system, the
UPS does not function.
• International (non-North American) users require the power supply
adapter cord to connect the power supply to the region specific power bar.
• Ensure the power supply is within 1.5 m (5 ft) of the BCM450 unit and
within 1.5 m (5 ft) of the UPS.
Procedure steps
Step Action
1
Plug one end of the USB cable into the USB port on the UPS.
2
Plug the other end of the USB cable into the top USB port on the
BCM450 main unit. This ensures that the bottom port is left available
for a USB storage device.
3
Plug the UPS power cord into the AC power source (wall outlet).

Connecting the BCM450 system to a power source
To power your BCM450 system, connect the main unit and expansion cabinet
to an AC power source. You can connect the power supplies through a UPS
or directly to the AC power source.
