Motherboard ConnectorsThere are connectors on the motherboard for the Power supply, HD audio, fans, frontpanel audio, front panel USB ad front panel connectors. The location and/or details ofthese connections are shown below.Front Panel ConnectorsFront Panel Connectors: JFP1These connectors are for electrical connection to the front panel switches and LEDs. TheJFP1 is compliant with Intel® Front Panel I/O Connectivity Design Guide.Figure 6: Front Panel ConnectorsTable 3: Front Panel Connectors (JFP1)Pin Connector Comments1-3Hard Drive Activity LEDHeader5-7 Reset Switch Header2-4 Power/Sleep LED Header6-8 Power Switch HeaderPins 1 and 3 can be connected to an LED to provide a visualindicator that data is being read from or written to a hard drive.Proper LED function requires a Serial ATA hard drive connected toan onboard Serial ATA connector.Pins 5 and 7 can be connected to a momentary single pole, singlethrow (SPST) type switch that is normally open. When the switch isclosed, the board resets and runs the POST.Pins 2 and 4 can be connected to a one- or two-colour LED. Thisdisplay if the computer is active or not.Pins 6 and 8 can be connected to a front panel momentary-contactpower switch. The switch must pull the SW_ON# pin to ground for atleast 50 ms to signal the power supply to switch on or off. (The timerequirement is due to internal debounce circuitry on the board.) Atleast two seconds must pass before the power supply will recognizeanother on/off signal.V1.0 Vig645M Motherboard Manual 19
Power ConnectorsATX 24-Pin Power Connector: JPWR1This connector allows you to connect an ATX 12V 24-pin power supply. To connect theATX 24-pin power supply, make sure the plug of the power supply is inserted in theproper orientation and the pins are aligned. Then push down the power supply firmly intothe connector.Figure 7: ATX 24-Pin Power ConnectorATX 12V Power Connector: JPWR2This 12V power connector is used to provide power directly to the CPU voltage regulatorand must be used. Failure to do so will prevent the motherboard from booting.NOTE:Figure 8: ATX 12V 4-PIN power connector Make sure that all the connectors are connected to proper ATX power supplies toensure stable operation of the Motherboard ATX 12V power connection should be greater than 18A. If a high power (75W or greater) add-in card is installed in the PCI Express connector,that card must be connected directly to the power supply. Failure to do so may causedamage to the motherboard and the add-in card.V1.0 Vig645M Motherboard Manual 20
