12 Implementing UPS Configurations with Microsoft Cluster Server

2.2.1.1 Battery source

The battery source is comprised of parallel, hot-swappable, 120 V battery

modules. These are housed in the Symmetra frame, and in an optional XR

Extension Battery frame. A Symmetra Miniframe provides bays for up to two

battery modules, and a Masterframe provides bays for up to four. Both of these

frames can be connected to an XR Extension Battery frame. Additional battery

modules increase battery run time.

2.2.1.2 Control

Symmetra incorporates a main intelligence module (MIM) that continuously

monitors the system. The MIM does the following:

• Coordinates the initial startup of the system

• Transfers it into and out of bypass mode

• Transfers the power source between the main AC power and the battery

source

• Coordinates shutdown operations

• Gathers data about the system components

• Delivers it to the Powerview interface and the computer interface ports

System status monitoring and reporting data includes the current predicted run

time, the status of individual battery and power modules, the size of input and

output voltage, the input and output voltage frequency, and the size and status of

the output load.

2.2.1.3 Alarm condition detection

The control/user interface system monitors Symmetra for alarm conditions. If an

alarm condition is detected, the Powerview user interface initiates an audible and

visual alarm. Alarm conditions include on-battery, low battery, module faults,

overloads, loss of redundancy and a variety of other default and user-defined

events.

The Symmetra comes in different VA ratings:

• Miniframe: 4 - 8 kVA

• Masterframe: 8 - 16 kVA

(always + one 4 kVA power module for N+1 redundancy)
