X7DBi+ User's Manual

Power Fault (PWR Supply Failure)

Connect a cable from your power supply to the Power Fail 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 deﬁnitions.

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 deﬁnitions.
