Fan Headers
There are eight fan headers on the
serverboard, all of which are 4-pin
headers. Pins 1-3 are backward com-
patible with the traditional 3-pin fans.
(Fan speed control is supported with
4-pin fans only.) See the table on the
right for pin denitions. The onboard
fan speeds are controlled by Thermal
Management (via IPMI).
NMI Button
The non-maskable interrupt button
header is located on pins 19 and 20
of JF1. Refer to the table on the right
for pin denitions.

Power On LED
The Power On LED connector is lo-
cated on pins 15 and 16 of JF1 (use
JLED for a 3-pin connector). This
connection is used to provide LED
indication of power being supplied to
the system. See the table on the right
for pin denitions.

Power LED/Speaker
On the JD1 header, pins 1-3 are for
a power LED and pins 4-7 are for the
speaker. Close pins 4-7 with a jumper
to use an external speaker. If you wish
to use the onboard speaker, please
close pins 6-7. See the table on the
right for speaker pin denitions.
Internal Speaker
The internal speaker, located at SP1,
can be used to provide audible indica-
tions for various beep codes. See the
table on the right for pin denitions..

SGPIO Headers
The SGPIO (Serial General Purpose
Input/Output) headers are used to
communicate with the enclosure
management chip on the backplane.
T-SGPIO1/2 support the I-SATA ports
and S-SGPIO1 supports the S-SATA
ports. See the table on the right for
pin denitions.
