The main logic module contains the single master power controller for the cell. The 
master power controller

Controls and monitors the power supplies, and monitors the voltages on all cell 
components

Communicates with the management system 

200-Volt Redundancy and AC Source Options 

A second AC/DC 12-volt power supply provides n+1 DC redundancy. If one power 
supply fails, the cell can continue operating at normal levels with the other power supply. 

A second AC source can be configured to provide AC redundancy. The two power 
supplies can also be configured for a non-redundant 100-volt operation. 

In addition, with a second power supply, you can increase system availability by 
attaching each power supply to a different power source, for example, to a different 
uninterruptible power supply (UPS). If one power source fails or is interrupted, the cell 
continues processing using the other power source. 

In a redundant 200V configuration, you can replace individual power supplies while a 
partition is running within that cell. 

Partitions and Power 

Partitions are made up of one or more cells. If a system contains multiple partitions, one 
partition can be powered off while the other partitions continue their processing. 
Clustering software also helps ensure continuous processing. 

Uninterruptible Power Supply (UPS) 

UPSs help sites minimize system downtime caused by AC disturbances. A UPS uses 
batteries to provide AC to the system if the AC input is lost or disturbed. The length of 
time a system runs on a UPS depends on the capacity of the UPS and the amount of 
power the system needs. 

The decision to provide alternate power sources, standby power generation, UPS, or a 
combination of these should be based on the economic consequences of a system 
interruption caused by a power outage or brownout (low voltage). A service 
representative can assist with this analysis.
