Soft Power Control
Failure
Asserted if the system fails to power on
due to the following power control
sources:
 Chassis Control command
 PEF action
 BMC Watchdog Timer
 Power State Retention
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.

Power Unit Failure
Power subsystem experienced a failure.
Asserted for one of the following
conditions:
 Unexpected de-assertion of
system POWER_GOOD signal.
 System fails to respond to any
power control source’s attempt to
power down the system.
 System fails to respond to any
hardware power control source’s
attempt to power on the system.
 Power Distribution Board (PDB)
failure is detected (applies only
to systems that have a PDB).
Indicates a power supply failed.
1. Remove and reapply AC power.
2. Verify all power cables and adapters are connected properly (AC
cables as well as the cables between the PSU and system
components).
3. Cross test the PSU if possible.
4. If the power supply still fails, replace it.
5. If the problems still exists, replace the baseboard.
4.3.2 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.
