Abstract:
A power management system, comprising:means for receiving a modular electronic component, the component having an associated known maximum power demand;means for querying the component, said means for querying having a first end and a second end connected together through said means for receiving, said first end adapted to couple said means for querying to the component; andmeans for supervising power utilization connected to said means for receiving and to said second end, said means for supervising adapted to query said means for querying and to receive therefrom an associated known maximum power demand of the component,wherein, said means for supervising includes a first voltage source coupled to said means for querying through a first resistance;said means for supervising senses said associated known maximum power demand by sensing a voltage level on said means for querying,said means for supervising causes a selected voltage level to be applied to said means for querying to cause the component to fully power up, andsaid means for supervising generates a power up signal which is sent over a line to a switch having a first state and a second state, said switch allowing power to flow onto said means for querying when in said first state and not allowing power to flow onto said means for querying when in said second state, said switch being in said second state in the absence of said power up signal and said switch being in said first state in the presence of said power up signal.
