Speaker Connector
An offboard speaker can be installed on the mainboard as a manufacturing
option. An offboard speaker can be connected to the mainboard at the front
panel connector. The speaker (onboard or offboard) provides error beep code
information during the Power On Self-Test when the computer cannot use the
video interface. The speaker is not connected to the audio subsystem and
does not receive output from the audio subsystem.
Reset Button
This connector can be attached to a momentary SPST switch. This switch is
usually open and when close will cause the mainboard to reset and run the
POST (Power On Self Test).
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.
HDD LED (Hard Drive LED Connector)
This connector can be attached to a 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.
Sleep Button (Green Button)
This connector is used to conserve energy by powering down the monitor and
the hard disk when not in use.
Power Button
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 de-
bounce circuitry on the system board). At least two seconds must pass before
the power supply will recognize another on/off signal.
