Pins 1 and 3 can be connected to an LED to provide a visual
indicator that data is being read from or written to a hard drive.
Proper LED function requires a Serial ATA hard drive connected to
an onboard Serial ATA connector.
Pins 5 and 7 can be connected to a momentary single pole, single
throw (SPST) type switch that is normally open. When the switch is
closed, the board resets and runs the POST.
Pins 2 and 4 can be connected to a one- or two-colour LED. This
display if the computer is active or not.
Pins 6 and 8 can be connected to a front panel momentary-contact
power switch. The switch must pull the SW_ON# pin to ground for at
least 50 ms to signal the power supply to switch on or off. (The time
requirement is due to internal debounce circuitry on the board.) At
least two seconds must pass before the power supply will recognize
another on/off signal.
