BCM200/400 4.0 Installation and Maintenance Guide
Power supply adapter cord (international users)
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.
Uninterruptable power supply
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).
Hard disk
The BCM200 main unit and the BCM400 main unit (standard) contain a single hard disk and hard
disk bracket (see
Figure 42 and Figure 43 ).
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.
