Power Fault (PWR Supply
Failure)
Connect a cable from your power
supply to the Power Failure header
(JPWF) 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.

Alarm Reset

If three power supplies are installed
and Alarm Reset (JAR1) is enabled,
the system will notify you when any
of the three power modules fails.
Connect JAR1 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.
