2.5 Rear I/O Connectors/Ports

UID/BMC Reset Switch (JUIDB1) and UID_LED/BMC LED Indicator
A UID LED/BMC Reset switch (JUIDB1) is located on the rear I/O panel of the motherboard.
This switch has dual functions. It can function as a unit identifier (UID) to identify a system
unit that is in need of service, and it can also be used for BMC reset.
To achieve these purposes, JUIDB1 works in conjunction with the UID_LED1/LEDBMC LED
indicator located on the rear I/O panel for both UID and BMC Reset support.
When functioning as a UID LED switch, JUIDB1 will turn on/off the blue signals of the UID_
LED1/LEDBMC LED indicator when the user presses the switch on/off.
When functioning as a BMC reset switch, JUIDB1 will reset the BMC settings to the
manufacturer defaults when the user presses and holds the switch for 12 seconds, and it will
trigger a cold reboot when the user presses and holds it for 6 seconds.
Refer to the BMC User's Guide posted on our website at http://www.supermicro.com for more
information.
