SATA Ports and M.2
The motherboard supports up to eight SATA3.0 ports (4 via ports and 4 via miniSAS HD
header). Using the Flexible I/O feature, a user can select a total of eight SATA ports and/or
PCIE lanes on the expansion slot.
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.

press the button for 4 seconds or longer.
