System is powered down.

AC removed.

Generally means power good was lost in the system, causing a shutdown.

Informational Event

This could be caused by the power supply subsystem or system components.

1. Verify all power cables and adapters are connected properly (AC cables as well as the cables between the PSU and system components).

2. Cross test the PSU if possible.

3. Replace the power subsystem.

Indicates a power supply failed.

1. Remove and reapply AC power.

2. If the power supply still fails, replace it.

4.2.2 Power Unit Redundancy Sensor

This sensor is enabled on systems that support redundant power supplies. When a system has AC applied or if it loses redundancy of the power supplies a message will get logged into the SEL.

Informational Event

This event should be accompanied by specific power supply errors (AC lost, PSU failure, and so on). Troubleshoot these events accordingly.
