Fan Headers
The X9DRD-iF has eight fan headers
(Fan1 ~ Fan8). These are all 4-pin fan
headers, however pins 1-3 are backward
compatible with traditional 3-pin fans.
A fan speed control setting in the BIOS
(Hardware Monitoring section) allows
the BIOS to automatically set fan speeds
based on the system temperature. Refer
to the table on the right for pin defi nitions.
Note: Please use all 3-pin fans or all 4-pin
fans on a serverboard. Do not mix 3-pin
fans and 4-pin fans on the same board.
Internal Speaker
The Internal Speaker, located at SP1, can
be used to provide audible indications for
various beep codes. See the table on the
right for pin defi nitions. Refer to the layout
below for the locations of the Internal
Buzzer (SP1).
Power LED/Speaker
On JD1 header, pins 1-3 are used for
power LED indication, and pins 4-7 are
for the speaker. See the tables on the
right for pin defi nitions. Please note that
the speaker connector pins (4-7) are used
with an external speaker. If you wish to
use the onboard speaker, you should
close pins 6-7 with a jumper.
