Serial ATA Connectors controlled by Intel ICH6: SATA1/2/3/4 The Intel ICH6 Southbridge supports four serial connectors SATA1~4. 1 7 SATA1~4 are high-speed Serial ATA interface ports. Each supports 1st GND generation serial ATA data rates of 150 MB/s. All SATA connectors are TXP GND RXP fully compliant with Serial ATA 1.0 specifications. Each Serial ATA TXN RXN GND connector can connect to 1 hard disk device. MSI Reminds You... Please do not fold the serial ATA cable into 90-degree angle. Otherwise, data loss may occur during transmission. CD-In Connector: CD_IN1 The connector is for CD-ROM audio connector. R L GND Fan Power Connectors: CPUFAN1/SYSFAN1 The 4-pin CPUFAN1 (processor fan) and 3-pin SYSFAN1 (system fan) support system cooling fan with +12V. CPUFAN1 can support three- or four-pin head connector. When GND +12V Sensor Control GND +12V Sensor connecting the wire to the connectors, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset onboard, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control. MSI Reminds You... Always consult the vendors for proper CPU cooling fan. Serial Port Connector: JCOM1 The mainboard provides one serial port header for you to connect secondary serial devices. SOUT GND RTS RI IrDA Infrared Module Header: JIR2 12 9 10 SIN DTR DSR CTS KEY The connector allows you to connect to IrDA Infrared module and is compliant with Intel Front Panel I/O Connectivity Design Guide. You must configure the setting through the BIOS setup to use the IR function. IRTX Chassis Intrusion Switch Header: JCASE2 2 GND 1 CINTRU This connector is connected to a 2-pin chassis switch. If the chassis is opened, the switch will be short. The system will record this status and show a warning message on the screen. To clear the warning, you must enter the BIOS utility and clear the record. Front Panel Connectors: JFP1/JFP2 The mainboard provides two front panel connectors for electrical connection to the front panel switches and LEDs. The JFP1 is compliant with Intel Front Panel I/O Connectivity Design Guide. 7 10 9 Power Switch Reset Switch Power LED HDD LED 21 JFP1 Speaker 2 8 1 7 Power LED JFP2
