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 man-
agement functions. Connect the appropriate
cable from the backplane to the T-SGPIO1
header to utilize SATA management func-
tions on your system.
Likewise, the 3-SGPIO1/3-SGPIO2 headers
provide the same function between the SAS
controller and the backpane, and have the
same pin defi nitions.
