Power Fault (PWR Supply
Failure)
Connect a cable from your power
supply to the Power Fail (PSF) header
(PW3) to provide a warning 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 (JPAR1) is enabled,
the system will notify you when any of
the three power modules fails. Con-
nect JPAR1 to a micro-switch to turn
off the alarm that is activated when a
power module fails. See the table on
the right for pin defi nitions.
