Cooling
The main logic module contains the single master power controller for the cell. The master power controller
yControls and monitors the power supplies, and monitors the voltages on all cell components
yResponds when someone presses the power button (to turn the power on or off)
yMonitors and controls the fans
yMonitors thermal sensors
yCommunicates with the management system
200-Volt Redundancy and AC Source Options
A second AC/DC
A second AC source can be configured to provide AC redundancy. The two power supplies can also be configured for a
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.
