M.2 Connection
The X11SSW-F contains an M.2 NGFF socket 3 connector at J23. M.2 was formerly known
as Next Generation Form Factor (NGFF) and serves to replace mini PCI-E and mSATA. M.2
allows for a greater variety of card sizes, increased functionality, and spatial efficiency. The
M.2 socket 3 supports both PCI 3.0 x4 (32 Gb/s) and SATA3 (6 Gb/s) M.2 cards in 2260,
2280 and 22110 form factors.
Unit Identifier Switch/UID LED Indicator
A rear Unit Identifier (UID) switch and a rear UID LED (LE1) are located next to the VGA port
on the motherboard. The front UID switch and the front UID LED are both located on the
Front Panel Control (JF1) (with the front UID switch on pin 13, and the front LED on pin 7
of JF1). When you press the front or the rear UID switch, both front and rear UID LEDs will
be turned on. Press the UID switch again to turn off the LED indicators. The UID Indicators
provide easy identification of a system unit that may be in need of service.
Note:
UID can also be triggered via IPMI on the motherboard. For more information on IPMI,
please refer to the IPMI User's Guide posted on our website at

Control Panel
JF1 contains header pins for various control panel connections. See the figure below for the
pin locations and definitions of the control panel buttons and LED indicators.
All JF1 wires have been bundled into a single cable to simplify this connection. Make sure
the red wire plugs into pin 1 as marked on the motherboard. The other end connects to the
control panel PCB board.
