UID (Unit Idencation)/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 (LE6) 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. For more details on the UID LEDs and BMC LEDs,
refer to the tables below. Also, refer to the BMC User's Guide posted on our website at http://
www.supermicro.com for more information on BMC.
