Power Unit Redundancy Sensor

This sensor is enabled on the 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.

Description
Generally means power good was lost in
the system, causing a shutdown.
Power subsystem experienced a failure.

This could be cause 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.
