Connecting pins 1 and 3 to a front panel mounted LED provides visual
indication that data is being read from or written to the hard drive. For
the LED to function properly, an IDE drive should be connected to the
onboard IDE interface. The LED will also show activity for devices
connected to the SCSI ( hard drive activity LED ) connector.
Connecting pis 2 and 4 to a signal- or dual-color, front panel mounted
LED provides power on/off, sleep, and message waiting indication.
Supporting the reset function requires connecting pins 5 and 7 to a
momentary-contact switch that is normally open. When the switch is
closed, the board resets and runs POST.
Supporting the power on/off function requires connecting pins 6 and 8
to a momentary-contact switch that is normally open. The switch
should maintain contact for at least 50ms to signal the power supply to
switch on or off. The time requirement is due to internal debounce
circuitry. After receiving a power on/off signal, at lease two seconds
elapses before the power supply recognizes another on/off signal.
