SGPIO
The T-SGPIO1/T-SGPIO2 (Serial
General Purpose Input/Output)
headers provide a bus between the
SATA controller and the backpane to
provide SATA enclosure management
functions. Connect the appropriate
cable from the backplane to the
T-SGPIO1 header to utilize SATA
management functions on your system.
Likewise, the 6-SGPIO1/6-SGPIO2
headers provide the same function
between the SAS controller and the
backpane, and have the same pin
definitions (only on H8SML-7 and
H8SML-7F).
