Power Unit Sensor
The power unit sensor indicates the status of the onboard power subsystem. If the power
subsystem fails to turn on the payload power, as indicated by the power unit power good
signal, a soft power control failure will be indicated. If the power unit power good signal is
deasserted after power has been successfully turned on, a power unit failure will be
indicated. This sensor is an IPMI sensor type Power Unit (09h).
states/offsets and its descriptions.
Power unit status sensor states
When a power fault has been detected, the contents of the CPLD "Power Fault1" and
"Power Fault2" registers are read and are stored as event data 2 (power fault 1
register) and event data 3 (power fault 1 register ) bytes in the SEL. The contents of
the event data are described in

Description
Asserted when system power is off, Deasserted when
power is on
Asserted and then deasserted as a result of a Power
Cycle request.
Power Cycle condition is the situation when power is
turned off, then immediately turned on.
Asserted if power unit did not respond to request to
turn on
Asserted if power unit changes power state
unexpectedly
