摘要：A selective, non-manual power controller provides the selective, non- manualpower control of various components of a data processing equipment from and reportsthe power status of such components to a central location. As opposed to pass powercontrollers which were limited to powering on or off all of the computer equipmentcontrolled by a given controlling element, this invention provides a non-manual capabilityfor remotely powering on or off any one or more components of a system or systems ina selective manner and providing the power status thereof. By being able to selectivelyactivate or deactivate any or all of the components of a data processing system, theability to conserve electrical energy is optimized. In many cases, a single component or aset of components are not used for extended periods of time, such as an entireproduction period or at least a large portion of a production period. For example, aperipheral subsystem or a particular peripheral device may be used solely for a certaintype of job which is active for only a portion of a production period. Alternatively, a
multiprocessor system may run as a unit processor system during evenings andweekends. The net result is a substantial saving in electrical energy that may beimplemented from and reported to a central location.
