SGPIO Headers
Four SGPIO (Serial General Purpose
Input/Output) headers are located on the
motherboard. These headers are used to
"talk to" the System Monitoring Chip on
the backplane. T-SGPIO0 and T-SGPIO1
are used to monitor SATA activities, while
3-SGPIO0 and 3-SGPIO1 are used for
SAS* connections. See the table on
the right for pin defi nitions. Refer to the
board layout below for the locations of
the headers.
