Chapter 4: Motherboard Connections
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.
M.2 Slot
The X11DDW-L/NT has one M.2 slot located at JM2_1. M.2 was formerly known as Next
Generation Form Factor (NGFF) and serves to replace mini PCI-E. M.2 allows for a variety of
card sizes, increased functionality, and spatial efficiency. The M.2 socket on the motherboard
supports PCI-E 3.0 x4 (32 Gb/s) SSD cards in the 2280 and 22110 form factors.
I-SATA 3.0 and S-SATA 3.0 Ports
The X11DDW-L/NT has eight I-SATA 3.0 ports (I-SATA0~3, I-SATA4~7) and six S-SATA ports
(S-SATA0~3, S-SATA4, S-SATA5). These SATA ports are supported by the Intel C620 chipset.
S-SATA4/S-SATA5 can be used with Supermicro SuperDOMs which are yellow SATA DOM
connectors with power pins built in, and do not require external power cables. Supermicro
SuperDOMs are backward-compatible with regular SATA HDDs or SATA DOMs that need
external power cables.
