Power Fault
Connect a cable from your power
supply to the Power Fault header
(JP12) to provide warnings of
power supply failure. This warn-
ing signal is passed through the
PWR_LED pin to indicate of a
power failure on the chassis. See
the table on the right for pin defini-
tions.

Note: This feature is only available when using
redundant Supermicro power supplies.
Power Fail Alarm Clear
Switch (Alarm Reset)
The system will notify you in the
event of a power supply failure.
To use this feature, you will need
to have the Supermicro redundant
power supply units installed in the
chassis. If you only have a single
power supply installed, you should
leave the pins open (the default
setting) to prevent false alarms.
See the table on the right for
jumper settings.
