Serial Ports
Two COM connections (COM1 &
COM2) are located on the motherboard.
COM1 is located on the Backplane I/O
panel. COM2, located next to Front
Accessible USB 4/5, is used to provide
front access serial support. See the
table on the right for pin defi nitions.
Fan Headers
This motherboard has six system/CPU
fan headers (Fan 1~Fan 4, Fan A, Fan
B) on the motherboard. All these 4-pin
fans headers are backward compatible
with the traditional 3-pin fans. However,
fan speed control is available for 4-pin
fans only. The fan speeds are controlled
by Thermal Management via Hardware
Monitoring in IPMI. (See Chapter 5 for
more details.) See the table on the right
for pin defi nitions.
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.
