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 SW (Reset Switch)
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).
ACPI 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 SW (Power Switch)
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.
