UID (Unit Identier)/BMC Reset Switch and UID/BMC Reset LED Indicators
A UID / 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 you press
and hold the switch for six seconds. It will also restore the BMC to the manufacturer's default
when you press and hold the switch for 12 seconds.
When functioning as a UID LED switch, JUIDB1 will turn both rear UID LED (LED4) and front
UID LED (Pin 7/Pin 8 of JF1) on and o󰀨 when you press the switch on/o󰀨.
To achieve these dual purposes, the UID LED/BMC Reset switch works in conjunction with
the BMC Heartbeat LED (BMC LED) and front/rear UID LEDs. Please note that UID can
also be triggered via BMC on the motherboard. For more details on the UID LEDs and BMC
LEDs, refer to the tables on next page. Also, refer to the BMC User's Guide posted on our
website at https://www.supermicro.com for more information on BMC.
