UID (Unit Idenfication)/BMC Reset Switch and UID/BMC Reset LED Indicators
A UID LED/BMC Reset switch (JUIDB1) is located on the rear side of the motherboard. This
switch has dual functions. It can be used to identify a system unit that is in need of service,
and it can also be used to reset the BMC settings.
When functioning as a BMC reset switch, JUIDB1 will trigger a cold reboot when the user
presses and holds the switch for 6 seconds. It will also restore the BMC to the manufacturer's
default when the user presses and holds the switch for 12 seconds.
When functioning as a UID LED switch, JUIDB1 will turn both rear UID LED (LE1) and front
UID LED (Pin 7/Pin 8 of JF1) on and off when the user presses the switch on/off.
To achieve these dual purposes, the UID LED/BMC Reset switch works in conjunction with
the BMC Heartbeat LED (LEDM1) and front/rear UID LEDs. Please note that UID can also
be triggered via BMC on the motherboard. Refer to the BMC User's Guide posted on our
website at http://www.supermicro.com
