SUPERSERVER
Serial Ports
Two COM connections (COM1 &
COM2) are located on the serverboard.
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 serverboard has six system/CPU
fan headers (Fan 1~Fan 4, Fan A,
Fan B) on the serverboard. 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 the Advanced Setting in the BIOS.
(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.
