ABSTRACT:
The invention is a hardware switching apparatus for initiating a soft power-down and a remote power-up in a computer system. The apparatus includes a power supply, a switching device having a first switch position and a second switch position, a switching circuit, and a wiring harness for remotely controlling the switching circuit. The power supply senses the power delivered from a primary source and produces a power-down signal when the power is interrupted. When the switching device is in the first switch position, the switching circuit is adapted to cause the power supply to produce a power-down signal. When the switching device is in the second switch position, the switching circuit is adapted to cause the power supply to produce a start-up signal.
