Power Force-On; Power Supply Failure - Supermicro X7DAL-E User Manual

Power Force On Enable/Disable
Jumper JPF allows you to enable or disable
the Power Force-On function. If enabled, the
power will always stay on automatically. If this
function is disabled (the normal setting), the
user needs to press the power button to power
on the system.
PWR Supply Failure/PWR Fault
Detect (JPWF)
The system can notify you in the event of a
power supply failure. This feature is available
when three power supply units are installed
in the chassis with one acting as a backup. If
you only have one or two power supply units
installed, you should disable this (the default
setting) with JPWF to prevent false alarms.
Note: This feature is only available when using
Supermicro redundant power supplies.
