The power supply adapter cord is for international (non-North American) BCM users. It connects 
to the power supply on one end and to the (C-14) BCM power bar on the other end. 

You require one power supply adapter cord for each power supply you want to connect to the 
power bar.

An uninterruptable power supply (UPS) is an optional device that maintains continuous operation 
during power interruption or failure conditions. The UPS provides power source monitoring and 
battery backup activation so that critical BCM functionality is maintained. 

In a power failure situation, the UPS provides sufficient time to either correct the problem or 
activate a contingency plan to sustain services. The UPS is configured to perform a graceful 
shutdown of the BCM 2 minutes before the UPS battery power is drained. 

The BCM system supports American Power Conversion (APC) UPS devices that use a USB 
control interface. These include the APC UPS-Smart family (for example, UPS-Smart 750, 
UPS-Smart 1000) and UPS-Back family (for example, UPS-Back 500 ES, UPS-Back 350 ES). 
The UPS control software enables the configuration of various operational settings.

On BCM systems with more than one unit, the power supplies for all of the units must be 
connected to a single UPS.

The UPS feature is supported in all markets (110~120V and 220~240V power standards). 

The BCM200 main unit and the BCM400 main unit (standard) contain a single hard disk and hard 
disk bracket (see 

 and 

Note: For the UPS to function correctly, connect the UPS before the BCM system 
is powered up. If you connect a UPS to a running system, the UPS will not 
function.

In BCM 4.0 the serial interface is not supported for UPS connectivity. Only the 
USB interface supports UPS connectivity.
