Pin 1 is assigned as +, and Pin 5 as -. The Power LED lights up when the system is powered ON. External Speaker and Internal buzzer Connector Pin 2, 4, 6 and 8 can be connected to the case-mounted speaker unit or internal buzzer. While connecting the CPU card to an internal buzzer, you need to short pins 2-4; while connecting to an external speaker, set pins 2-4 to Open and connect the speaker cable to pin 8 (+) and pin 2 (-). ATX Power On/Off Button This 2-pin connector named as Pin 9 and 10 connects the front panel’s ATX power button to the CPU card, which allows users to control ATX power supply to be on/off. System Reset Switch Pin 11 and 12 can be connected to the case-mounted reset switch that reboots your computer instead of turning OFF the power switch.
