4.3.3.1 Node Auto Shutdown Sensor – Next Steps
This event is accompanied by specific power supply errors (AC lost, PSU failure, and so on) or other system events. Troubleshoot
these events accordingly.
4.4 Power Supply
The BMC monitors the power supply subsystem.
4.4.1 Power Supply Status Sensors
These sensors report the status of the power supplies in the system. When a system first AC applied or removed, it can log an event.
Also if there is a failure, predictive failure, or a configuration error, it can log an event.
