Reset Button
The Reset Button connection is located

hardware reset switch on the computer
case to reset the system. Refer to the

Power Button
The Power Button connection is located
on pins1 and 2 of JF1. Momentarily
contacting both pins will power on/off
the system. This button can also be
confi gured to function as a suspend
button (with a setting in the BIOS - see
Chapter 4). To turn off the power in the
suspend mode, press the button for at
least 4 seconds. Refer to the table on
the right for pin defi nitions.
Fan Headers
The C7X99-OCE has fi ve fan headers
(Fan 1~Fan 5). These fans are 4-pin
fan headers. Although pins 1-3 of the
fan headers are backward compatible
with the traditional 3-pin fans, we
recommend the use 4-pin fans to take
advantage of the fan speed control.
This allows the fan speeds to be
automatically adjusted based on the
motherboard temperature. Refer to the
table on the right for pin defi nitions.
Chassis Intrusion
A Chassis Intrusion header is located
at JL1 on the motherboard. Attach the
appropriate cable from the chassis to
inform you of a chassis intrusion when
the chassis is opened.
