Power Fault (PWR Supply

Connect a cable from your power sup-
ply to the Power Fail 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 denitions.
Note: This feature is only available when
using Supermicro redundant power sup-
plies.
