HD LED (Hard Drive LED Connector/ red)
This connector can be attached to an LED on the front panel of a computer case. The LED
will flicker during any disk activity.
RST SW (Reset Connector/ blue)
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).
PWR-LED (2-pin Power LED/ green)
The mainboard provides a two-pin power LED connector. If there is a 2-pin power LED
cable on the front panel of your computer case, you can attach it to the 2-pin power LED
connector. The LED will illuminate showing that the computer is powered on.
PWR ON (Power Button/ orange)
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.
PWR-LED (3-Pin Power LED/ green)
These mainboards provides a 3-pin power LED connector. If there is a 3-pin power LED
cable on the front panel of a computer case, you can attach it to the 3-pin power LED
connector. The LED will illuminate showing that the computer is powered on.
SPEAKER (Speaker/ violet)
A front panel speaker can be attached to this connector. This speaker is used for audible
beeps during the boot up process (Power On Self-Test). A single "short beep" is normal,
while "irregular beeps" signal problems.
