Power LED
The Power LED connector is located on pins 15 
and 16 of JF1. This con- nection is used to 
provide LED indica- tion of power being sup- 
plied to the system. See the table on the right 
for pin definitions. 
NMI Button
The non-maskable interrupt button header is 
located on pins 19 and 20 of JF1. Refer to the 
table on the right for pin definitions. 
 
 
Fan Headers
The embedded board has two fan headers. 
Fan1 is the CPU fan and Fan2 is for the system 
cooling fan. These fans are 4-pin fan headers. 
However, Pins 
1~3 of the fan headers are backward compatible 
with the traditional 3-pin fans. (The speeds of 4- 
pin (PWM) fans are controlled by Thermal Man- 
agement via BIOS Hardware Moni- toring in 
the Advanced Setting. (The default setting is 
Disabled.) Note: Please use all 3-pin fans or all 
4-pin fans on a motherboard. Please do not use 
3-pin fans and 4-pin fans on the 
same board. 
Overheat/Fan Fail LED (JOH)
The JOH header is used to connect an LED to 
provide warnings of chas- sis overheat. This 
LED will also blink to indicate a fan failure. Refer 
to the table on right for pin definitions.
