Power Fault (PWR Supply
Failure)
Connect a cable from your power
supply to the Power Fail (PSF) header
(JP3) 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
Super Micro 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.
