Abstract
A power distribution system comprises an input power line configured to supply power produced by a power source, one or more power distribution components operatively connected to receive power supplied by the power source, one or more intelligent system resources, and a power management component. Each power distribution component has one or more power outputs for distributing power along a power line connected thereto and is configured to modulate a carrier signal containing identification data along the power line connected to each output. Each system resource is operatively connected to receive power distributed by at least one of the one or more power distribution components. Each system resource is configured to receive and demodulate the carrier signal modulated by each power distribution component from which it receives power, generate a list of each power distribution component from which it receives power, and pass the list to a system bus. The power management component is configured to receive and process each list from the system bus to generate a mapping of the at least power distribution component from which each system resource receives power.
