VGA Connector
A VGA connector (JVGA) is located next
to the COM1 port on the IO backplane.
Refer to the board layout below for the
location.

GPIO Headers
Four GPIO (Serial Links General Purpose
Input/Output) headers are located at J7,
J8, J9, J10 on the motherboard. These
headers are used to communicate with
the Seriel-Links System Monitoring chip
on the backplane. J7 and J8 are used to
monitor SATA activities, J9 and J10 are
used to monitor SAS connections. See
the table on the right for pin denitions.
Refer to the board layout below for the
locations of the headers.
(J9, J10: X7DCL-3 Only.)
