66 Chapter 2 Introducing the BCM hardware

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.

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.

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 41 and Figure 42).
