Connector Configuration
Front Panel Indicator: SW/LED
HD LED (Hard Drive LED Connector)
This connector can be attached to an LED on the front panel of a computer case. The LED will
flicker during disk activity. This disk activity only applies to those IDE drives directly attached
to the system board.
RST (Reset Button)
This connector can be attached to a momentary SPST switch. This switch is normally left open.
When closed it will cause the mainboard to reset and run the POST (Power On Self Test).
PWR-LED (Power LED Connector)
This connector can be attached to an LED on the front panel of a computer case. The LED will
illuminate while the computer is powered on.
PWR ON (Power Button)
This connector can be attached to a front panel power switch. The switch must pull the Power
Button pin to ground for at least 50 ms to signal the power supply to switch on or off (the time
required is due to internal debounce circuitry on the system board). At least two seconds must
pass before the power supply will recognize another on/off signal.

This mainboard complies with the ATX standard, which means the ACPI connector
on this board is 2-pin. If the Power LED cable of your case uses a 3-pin adapter, you
must use the 2-pin to 3-pin adapter (Please read the Appendix II).
