Hard Drive Activity LED
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.

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 pin 5 and 7 to a momentary-contact switch that is normally
open. When the switch is closed, the board resets and runs POST.
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 de-bounce circuitry. After receiving a power on/off signal, at
least two seconds elapses before the power supply recognizes another on/off signal.
