Description
00h
Fully redundant
System is fully operational.
Informational Event
01h
Redundancy lost
System is not running in
redundant power supply mode.
This event is 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
4.3.3 Node Auto Shutdown Sensor
The BMC supports a Node Auto Shutdown sensor for logging a SEL event due to an emergency shutdown of a node due to loss of
power supply redundancy or PSU CLST throttling due to an over-current warning condition. This sensor is applicable only to multi-
node systems.
The sensor is rearmed on power-on (AC or DC power-on transitions).
