OH/Fan Fail Indicator
The Overheat (OH) / Fan Fail LED is located on pin 8 on the front control panel (JF1). When
this is on, it indicates that there is a system overheat or the internal fan(s) have failed.
UID LED Indicator
A Unit Identier (UID) switch and UID LED are located on the I/O backpanel, one UID LED
indicator header is located on JF1. The rear UID LED (UID LED) is located next to the UID
switch. The front UID LED is located on pins 7 & 8 on the front control panel (JF1). When
you press the UID switch, both rear and front UID LED indicators will be turned on. Press the
UID switch again to turn off the LED indicators. Use this UID Indicator system to 'mark' the
system, so the system can be easly identied whether on the front or back (e.g., a system
rack with multiple units installed).
Note: UID can also be triggered via IPMI on the serverboard. For more information on IPMI,
please refer to the IPMI User's Guide posted on our website @ http://www.supermicro.com.
