Abstract
A system and method for remotely power cycling a peripheral subsystem. A host system to remotely control the power cycling of a peripheral subsystem, without the need to include or add any dedicated or special signals beyond those needed for the normal interface between the host system and peripheral subsystem. A peripheral subsystem according to the present invention includes circuitry that senses the presence of a downstream, running switching signal such as a clock line or any “heart beat” type signal such as a clock pulse and initiates the power up event of the peripheral system. Conversely, the same circuitry also senses the absence of a downstream signal and initiates a power down event of the peripheral subsystem.
