SATA Ports
Eight SATA 3.0 ports are supported by the chipset. These SATA ports support RAID 0, 1, 5,
and 10. In addition, there are also two S-SATA ports (S-SATA0, S-SATA1) that include SATA
DOM power.
For more information on the SATA HostRAID configuration, refer to the Intel SATA HostRAID

One connector is located at NVME0/1 to support two PCIe 4.0 x4 NVMe connections. This
connector provides high-speed and low-latency connections directly from the CPU to NVMe
Solid State (SSD) drives.

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.
