System Power Supply  53  
Table 4-3  Class: HP_PowerCollection 
Property name  Property implementation 
GroupOperationalStatus[0] Represents the most severe power redundancy status 
and non-fault tolerant power supply operational status: 
•  0 (Unknown) —If power collection status is 
unknown 
•  2 (OK) —If power supplies are operating properly
•  3 (Degraded) —If no 
HP_WinPowerSupply.OperationalStatus[0] for all 
non-fault tolerant power supplies report 6 (Error) 
and 
HP_WinPowerRedundancySet.RedundancyStatus 
for any power redundancy sets report 3 
(Degraded Redundancy) or 4 (Redundancy Lost) 
and no power redundancy sets report 5 (Overall 
Failure). If the system starts up with a redundancy 
status set to 4 (Redundancy Lost) and no power 
supplies were removed or failed, 
GroupOperationalStatus is set to 2 (OK) because 
this is a valid configuration. 
•  6 (Error) —If 
HP_WinPowerSupply.OperationalStatus[0] for 
any non-fault tolerant power supplies report 6 
(Error) or if 
HP_WinPowerRedundancySet.RedundancyStatus 
for any power redundancy sets report 5 (Overall 
Failure). 
Note: If the system starts up with a redundancy status 
set to 4 (Redundancy Lost) and no power supplies have 
been removed or failed, the GroupOperationalStatus is 
set to 2 (OK) because this is a valid configuration. 
GroupStatusDescriptions[0] 
•  Unknown status for power supplies, if 
GroupOperationalStatus[0] is 0 (Unknown). 
•  Power supplies are operating 
properly, if GroupOperationalStatus[0] is 2 
(OK). 
•  Fault tolerant power supplies are 
degraded, if GroupOperationalStatus[0] is 3 
(Degraded). 
•  Power supplies have failed, if 
GroupOperationalStatus[0] is 6 (Error). 
 
4.3.3HP_PowerRedundancySet 
HP_PowerRedundancySet is used to model power supply redundancy sets on Integrity servers. The 
Windows implementation class is HP_WinPowerRedundancySet.
