T-Sgpio Headers; Overheat Led/Fan Fail (Joh1) - Supermicro Supero X8DTU-F User Manual

T-SGPIO Headers

Two SGPIO (Serial-Link General
Purpose Input/Output) headers (T-
SGPIO-1/T-SGPIO-2) are located at
below the front panel control connec-
tor (JF1) on the motherboard. These
headers support serial link interfaces
for the onboard SATA connectors. See
the table on the right for pin defini-
tions. Refer to the board layout below
for the location.

Overheat LED/Fan Fail (JOH1)

The JOH1 header is used to connect
an LED indicator to provide warnings
of chassis overheating or fan failure.
This LED will blink when a fan failure
occurs. Refer to the table on right for
pin definitions.
