Unit Identifier Switch/UID LED Indicator
A Unit Identifier (UID) switch (UID) and a UID LED Indicator (LE1) are located on the I/O
back panel. When you press the UID switch, the UID LED indicator will be turned on. Press
the UID switch again to turn off the LED. The UID Indicator provides easy identification of a
system unit that may be in need of service.
Note: UID can also be triggered via IPMI on the motherboard. For more information on IPMI,
please refer to the IPMI User's Guide posted on our website at http://www.supermicro.com.
