The pin headers on the motherboard are often associated with important functions. With the shunt (Jumper)
pushed down on the designated pins (the pin numbers are printed on the circuit board, surrounding the pin
header), certain feature can be enabled or disabled. While changing the jumpers, make sure your system is
turned off.
Jumper Setting
To short the designated pins, push the jumper down on them so that they become SHORT. To make the
pins setting OPEN, simply remove the jumper cap.
