1.10.11.7 Remote ON/OFF and Soft Power Support
For power supplies that support the Remote ON/OFF feature, this 2 pin header (see Figure 4 pins
1 and 2 of J9E2) should be connected to the system power ON/OFF switch. The power ON/OFF
button should be a momentary SPST switch that is normally open. The power supply control
signal (PS_ON) is supported via the primary power connector. Traditional power supplies with
mechanical ON/OFF switches that do not support remote ON/OFF or “soft-off” will by-pass this
circuit.
After turning the system ON by pushing the power ON/OFF button, the TE430VX motherboard
(with a power supply that supports remote power on/off) can be turned OFF from one of two
sources: the front panel power ON/OFF switch, or a “soft off” signal (coming from the Super I/O
controller) that can be controlled by the operating system. In “soft off”, an APM command issued
to the system BIOS will cause the power supply to turn OFF via the “PS ON” control signal on the
power connector. For example, Windows 95 will issue this APM command when the user clicks
on the Shutdown icon. Power can be restored by simply pressing the power ON/OFF switch at
which time the system will power back up and run POST.
1.10.12 Back Panel Connectors
The back panel provides external access to PS/2 style keyboard and mouse connectors, two USB
connectors, one parallel port, one serial port, a VGA connector, a MIDI/game port, and the external
audio jacks which are integrated on the motherboard. Figure 5 shows the general location of the
I/O connectors.
