1）System power LED pins（Pin 1、Pin 2 PWRLED）
Connect system power LED cable with these pins.（pin 1 is LED anode）When system is power
on, power LED is on；when system is power off, power LED is off.
2）HD LED Pins（Pin 3、Pin 4 HDD LED）
Usually there is an HD device running status indicator on the chassis panel. When HD reads
and writes, the indicator flashes, indicating that the HD device is in operation. Connect the
cable of the HD running status indicator on the chassis panel to this connector (Pin 4 is LED
cathode).
3）Buzzer Pins（Pin 5、Pin 6 SPEAKER）
External Pin for Speaker
4）Reset Button Pins（Pin 7、Pin 8 RESET）
