Control Panel
JF1 contains header pins for various control panel connections. See the figure below for the
pin locations and definitions of the control panel buttons and LED indicators.
All JF1 wires have been bundled into a single cable to simplify this connection. Make sure
the red wire plugs into pin 1 as marked on the motherboard. The other end connects to the
control panel PCB board.
Reset Button
The Reset Button connection is located on pins 3 and 4 of JF1. Attach it to a hardware reset
switch on the computer case.

Connect an LED cable to pins 7 and 8 of JF1 to use the Overheat/Fan Fail LED connections.
The LED on pin 8 provides warnings of overheat or fan failure.
Power Button
The Power Button connection is located on pins 1 and 2 of JF1. Momentarily contacting both
pins will power on/off the system. This button can also be configured to function as a suspend
button (with a setting in the BIOS - see Chapter 7). To turn off the power when the system
is in suspend mode, press the button for 4 seconds or longer.
