Hex Description
00h fully redundant System is fully operational Informational Event
01h redundancy lost
System is not running in redundant
power supply mode This event should be accompanied by specific power supply errors (AC
lost, PSU failure, and so on). Troubleshoot these events accordingly
02h redundancy degraded
03h non-redundant, sufficient from redundant
04h non-redundant, sufficient from insufficient
05h non-redundant, insufficient
06h non-redundant, degraded from fully redundant
07h redundant, degraded from non-redundant
4.3 Power Supply
The BMC monitors the power supply subsystem.
