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.

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).
This sensor is only used for triggering SEL to indicate node or power auto shutdown assertion or deassertion.
