Hard Drive Activity LED
Connecting pins 1 and 3 to a front panel mounted LED provides visual indica-
tion 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 inter-
face. The LED will also show activity for devices connected to the SCSI (hard
drive activity LED) connector.
Power / Sleep / Message Waiting LED
Connecting pins 2 and 4 to a single- or dual-color, front panel mounted LED
provides power on/off, sleep, and message waiting indication.
Reset Switch
Supporting the reset function requires connecting pins 5 and 7 to a momen-
tary-contact switch that is normally open. When the switch is closed, the board
resets and runs POST.
Power Switch
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 50 ms 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 least two seconds elapses before the power supply recog-
nizes another on/off signal.
