X7DB8-X/X7DBE-X User's Manual
Power Fault (PWR Supply
Failure)
Connect a cable from your power
supply to the Power Fail (PSF) header
(JP3) to provide a warning in the
event of a 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 (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.
