3.2 Headers and Connectors

Front Panel Controls
Front panel controls are connected to the JF1 header on the motherboard. The JF1 pins
used are pins 1-4 and 13-16. Two four pin plugs at JF1 are cabled to one eight pin plug at
the PCB connected to the chassis power button.
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.
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.
