T-SGPIO 0/1 & 3-SGPIO 0/1 Headers
Two T-SGPIO (Serial-Link General Pur-
pose Input/Output) headers are located
next to USB 6 and USB 7 connectors
on the motherboard. Additionally, two
3-SGPIO ports are also located next to
SAS Port 3 on the X8STi-3F motherboard.
These headers are used to communicate
with the enclosure management chip in
the system. See the table on the right for
below for the locations of the headers.
Alarm Reset
If three power supplies are installed and
Alarm Reset (JAR) is connected, the sys-
tem will notify you when any of the three
power modules fail. Connect JAR to a
micro-switch to turn off the alarm that is
activated when a power module fails. See
