Alarm Reset (JAR)
The system will notify you in the event
of a power supply failure. This feature
assumes that Supermicro redundant
power supply units are installed in the
chassis. If you only have a single power
supply installed, you should not connect
anything to this jumper to prevent false
alarms. See the table on the right for
jumper settings.
