Most fan headers possess a foolproof insertion design. When connecting a fan cable, be sure to connect it in the correct orientation (the black connector wire is the ground wire). The motherboard supports CPU fan speed control, which requires the use of a CPU fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis. • Be sure to connect fan cables to the fan headers to prevent your CPU and system from overheating. Overheating may result in damage to the CPU or the system may hang. • These fan headers are not configuration jumper blocks. Do not place a jumper cap on the headers.

If more than two hard drives are configured, the total number of hard drives must be an even number. • A RAID 10 configuration requires four hard drives. (Note) When a RAID configuration is built across the SATA 6Gb/s channels, the system performance of the RAID configuration may vary depends on the devices are connected. DEBUG PORT DEBUG PORT 11) SATA2/SATA3/SATA4/SATA5 (SATA 3Gb/s Connectors) 12) SATA0/SATA1 (SATA 6Gb/s Connectors) The SATA connectors conform to SATA 6Gb/s standard and are compatible with SATA 3Gb/s and 1.5Gb/s standard. Each SATA connector supports a single SATA device.

Out of the 4 signals, 3 are driven by the HBA and 1 is driven by the backplane. Typically, the HBA is a storage controller located inside a server, desktop, rack or workstation computer that interfaces with Hard disk drives (HDDs) to store and retrieve data. 8 1 7 2 Pin No. Definition 1 SGPIO_SATA_DATAOUT1 2 No Pin 3 SGPIO_SATA_DATAOUT0 4 GND 5 GND 6 SGPIO_SATA_LOAD 7 NC 8 SGPIO_SATA_CLOCK - ...
