16 Chapter 1 Uninterruptable Power Supply (UPS) Overview
P0607274 02
The UPS device is supported in all markets (110~120V and 220~240V power standards). All
BCMs using version 3.5 software or higher can use the UPS device.
BCM and UPS power and control connections
The UPS device operates in parallel with the BCM 200, 400, and 1000. The BCM obtains power
through the UPS. The UPS obtains power from a conventional AC power source.
The UPS meets BCM power delivery requirements for 110~120 and 220~240 Volt standards. The
BCM operational power usage range (shown in the following table) is compatible with the UPS
operating range.
The serial connection between the BCM and UPS provides power monitoring and control
capability. The UPS service uses standard RS232 serial protocol. Figure 2 shows the physical
BCM connections and OAM topology.
