••When removing the cable connected to a back panel connector, first remove the cable from your device and then remove it from the motherboard. ••When removing the cable, pull it straight out from the connector. Do not rock it side to side to prevent an electrical short inside the cable connector. 1-7 Internal Connectors 3 1 2 5 7 11 5 9 4 8 10 6 5 1) ATX_12V 2) ATX 3) CPU_FAN 4) SYS_FAN 5) SATA2 0/1/2/3/4/5 6) F_PANEL 7) F_AUDIO 8) F_USB1/F_USB2 9) COM 10) CLR_CMOS 11) BAT Read the following guidelines before connecting external devices: ••First make sure your devices are compliant with the connectors you wish to connect. ••Before installing the devices, be sure to turn off the devices and your computer. Unplug the power cord from the power outlet to prevent damage to the devices. ••After installing the device and before turning on the computer, make sure the device cable has been securely attached to the connector on the motherboard. 1/2) ATX_12V/ATX (2x2 12V Power Connector and 2x12 Main Power Connector) With the use of the power connector, the power supply can supply enough stable power to all the components on the motherboard. Before connecting the power connector, first make sure the power supply is turned off and all devices are properly installed. The power connector possesses a foolproof design. Connect the power supply cable to the power connector in the correct orientation. The 12V power connector mainly supplies power to the CPU. If the 12V power connector is not connected, the computer will not start. To meet expansion requirements, it is recommended that a power supply that can withstand high power consumption be used (500W or greater). If a power supply is used that does not provide the required power, the result can lead to an unstable or unbootable system.

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 speed control function requires the use of a fan with fan speed control design. For optimum heat dissipation, it is recommended that a system fan be installed inside the chassis.

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. 5) SATA2 0/1/2/3/4/5 (SATA 3Gb/s Connectors, Controlled by AMD SB710 South Bridge) The SATA connectors conform to SATA 3Gb/s standard and are compatible with SATA 1.5Gb/s standard. Each SATA connector supports a single SATA device. The AMD SB710 South Bridge supports RAID 0, RAID 1, RAID 10, and JBOD. Refer to Chapter 4, "Configuring SATA Hard Drive(s)," for instructions on configuring a RAID array. 1 Pin No. Definition 1 GND 2 TXP 3 TXN 4 GND 5 RXN 6 RXP 7 GND SATA2 7 7 1 SATA2 SATA2 1 7 1 7 ••A RAID 0 or RAID 1 configuration requires at least two hard drives. If more than two hard drives are to be used, the total number of hard drives must be an even number. ••A RAID 10 configuration requires four hard drives. 6) F_PANEL (Front Panel Header) Connect the power switch, reset switch, speaker, chassis intrusion switch/sensor and system status indicator on the chassis to this header according to the pin assignments below. Note the positive and negative pins before connecting the cables. Message/Power/ Sleep LED Power Switch Speaker MSG+ PW+ SPEAK+ SPEAK- ..............
