Power Fault (PWR Supply Failure)

Connect a cable from your power

supply to the Power Fail (PSF) header

to provide warnings of power supply

failure. This warning 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

defi nitions.
Note: This feature is only available when using
Supermicro redundant power supplies.
Alarm Reset

If three power supplies are installed

and Alarm Reset (JAR) is enabled, the

system will notify you when any of the

three power modules fails. Connect

JAR to a micro-switch to enable you

to turn off the alarm that is activated

when a power module fails. See the

table on the right for pin defi nitions.
