Hardware installation 22 22
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 22
With the use of the power connector the power supply can supply enough stable power to all the com ponents 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 con nector mainly supplies power to the cpu if the 12v power connector is not connected the computer will not start 22
23 hardware installation 23
4 5 cpu_fan sys_fan1 sys_fan2 pwr_fan fan headers 23
Clr_cmos clearing cmos jumper 23
The motherboard has a 4 pin cpu fan header cpu_fan a 3 pin sys_fan2 and a 4 pin sys_ fan1 system fan headers and a 3 pin power fan header pwr_fan 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 recom mended that a system fan be installed inside the chassis 23
Use this jumper to clear the cmos values e g date information and bios configurations and reset the cmos values to factory defaults to clear the cmos values place a jumper cap on the two pins to temporarily short the two pins or use a metal object like a screwdriver to touch the two pins for a few seconds 23
A raid 0 or raid 1 configuration requires at least two hard 24
A raid 10 configuration requires four hard drives 24
Always turn off your computer and unplug the power cord before replacing the battery replace the battery with an equivalent one danger of explosion if the battery is replaced with 24
An incorrect model 24
Bat battery 24
Contact the place of purchase or local dealer if you are not able to replace the battery by your 24
Drives if more than two hard drives are to be used the total number of hard drives must be an even number 24
Hardware installation 24 24
Of the battery the positive side should face up 24
Sata2_0 1 2 3 4 5 sata 3gb s connectors controlled by amd sb710 south bridge 24
Self or uncertain about the battery model 24
The battery provides power to keep the values such as bios configurations date and time information in the cmos when the computer is turned off replace the battery when the battery voltage drops to a low level or the cmos values may not be accurate or may be lost 24
The sata connectors conform to sata 3gb s standard and are compatible with sata 1 gb 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 5 configuring sata hard drive s for instructions on configuring a raid array 24
Used batteries must be handled in accordance with local environmental regulations 24
When installing the battery note the orientation of the positive side and the negative side 24
F_panel front panel header 25
Audio signals will be present on both of the front and back panel audio connections simultane 26
F_audio front panel audio header 26
Front panel audio module refer to the instructions on how to activate ac 97 functionality via the audio software in chapter 5 configuring 2 4 5 7 channel audio 26
Hardware installation 26 26
Instead of a single plug for information about connecting the front panel audio module that has different wire assignments please contact the chassis manufacturer 26
Ously if you want to mute the back panel audio only supported when using an hd front panel audio module refer to chapter 5 configuring 2 4 5 7 channel audio 26
Some chassis provide a front panel audio module that has separated connectors on each wire 26
Spdif_out s pdif out header 26
The front panel audio header supports hd audio by default if your chassis provides an ac 97 26
The front panel audio header supports intel high definition audio hd and ac 97 audio you may connect your chassis front panel audio module to this header make sure the wire assignments of the module con nector match the pin assignments of the motherboard header incorrect connection between the module connector and the motherboard header will make the device unable to work or even damage it 26
This header supports digital s pdif out and connects a s pdif digital audio cable provided by expan sion cards for digital audio output from your motherboard to certain expansion cards like graphics cards and sound cards for example some graphics cards may require you to use a s pdif digital audio cable for digital audio output from your motherboard to your graphics card if you wish to connect an hdmi display to the graphics card and have digital audio output from the hdmi display at the same time for information about connecting the s pdif digital audio cable carefully read the manual for your expan sion card 26

Coma serial port header 27
Cord from the power outlet to prevent damage to the usb bracket 27
Do not plug the ieee 1394 bracket 2x5 pin cable into the usb header prior to installing the usb bracket be sure to turn off your computer and unplug the power 27
F_usb1 f_usb2 usb headers 27
The com header can provide one serial port via an optional com port cable for purchasing the op tional com port cable please contact the local dealer 27
The headers conform to usb 2 1 specification each usb header can provide two usb ports via an optional usb bracket for purchasing the optional usb bracket please contact the local dealer 27
When the system is in s4 s5 mode only the usb ports routed to the f_usb1 header can sup port the on off charge function 27
