Serial Ports
Two serial ports are included on the
serverboard: COM1 is a port located
beside the USB ports and COM2 is
a header located on the corner of the
board near the SIMLC slot. See the
table on the right for pin defi nitions.
Note: Pin 10 is included on the header but not on
the port. NC indicates no connection.

SGPIO Headers
Four 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. T-
SGPIO1 and T-SGPIO2 are used to
monitor SATA activity while 3-SGPIO1
and 3-SGPIO2 (X7DCL-3 only) are
used for SAS activity. See the table on
the right for pin defi nitions.

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 defi nitions.
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 with a jumper.
