Power Sub-system

The system can support up to two 650 Watt power supply modules providing support for either a
non-redundant 1+0 or redundant 1+1 power configuration. In a 1+1 redundant configuration,
each power supply module is hot-swappable should one fail.
The power sub-system has several integrated management features including:
•
Status LED on each power module
•
Over temperature protection circuitry
•
Over voltage protection circuitry
•
Over current and 240VA protection circuitry
•
Power dropout and brownout recovery
With the addition of Server Management Software, the power subsystem is capable of
supporting several system management features including:
•
Remote Power On/Off
•
Status Alerting
•
Module and PDB FRU Information Reporting
•
PSMI Capabilities:
Thermal management
•
Relative temperature sensor for monitoring hot spot in power supply
•
Fan speed sensor
•
System control of power supply fan
•
Power supply fan control override indicator
