HDD/FP UID Button
The HDD/UID button connections are located
on pins 13/14 of JF1. Attach a hard-drive LED
cable to display HDD or SATA activity. This
connection can also be used for the front
panel UID (Unit Identifier) button. (The UID
LED on pin 7 of JF1 works in conjunction with
the UID button.) When the user presses and
releases the UID button, the UID LED will be
turned on or off to indicate the location of
the unit in a stack or rackmounted servers.
Power On LED
The Power On LED connector is located on pins
15 and 16 of JF1. This connection is used to
provide LED indication of power being sup-
plied to the system. See the table on the right
for pin definitions.
Fan Headers
The serverboard has twelve fan headers. Fans
1~4 are for CPU/system use and Fans A~H for
GPU use.. All are 4-pin fan headers, which are
backward compatible with traditional 3-pin
fans. However, fan speed control is available
for 4-pin fans only. See the table on the right
for pin definitions.
Serial Ports
A COM Port (COM1) is located next to the UID
switch to provide serial port support. See the
table on the right for pin definitions.
