Onboard Speaker (SP1)
The onboard speaker provides audible
indications for carious beep codes. See
the table on the right for pin definitions.
Power LED/Speaker
On the JD1 header, pins 1-3 are for a
power LED and pins 4-7 are for the
speaker. See the table on the right
for speaker pin definitions.
Note: The speaker connector pins
are for use with an external speaker.
If you wish to use the onboard
speaker, you should close pins 6-7

Two SGPIO (Serial General Purpose
Input/Output) headers are included
on the serverboard. These headers are
used to communicate with the System
Monitoring chip on the backplane and
provide a serial interface to the SATA
ports. See the table on the right for

An onboard I-Button, located next to
USB ports 2~3, is a 1-wire computer
chip enclosed in a durable stainless
steel can. The I-Button stores instr-
