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.
Unit Identifi er Button
There is a Unit Identifi er (UID) button on the
rear I/O of the board. There is also another
UID button located on the control panel.
When you push either UID button, both
Rear UID and Front Panel UID Indicators will
illuminate. Push either button again to turn off
both indicators. These UID indicators provide
easy identifi cation of a system unit that may
be in need of service.

may be connected to provide front side
access. A USB cable (not included) is needed
