System for distributing power in CPCI computer architecture

摘要

A system for distributing power in a compact peripheral component interconnect (CPCI) computer architecture is provided. A CPCI computer architecture comprises a plurality of CPCI systems each having respective backplanes. The backplanes further having respective local power rails providing power for a corresponding one of the plurality of CPCI systems. The power distribution system provides power to the backplanes, and comprises a common power rail connected to each one of the local power rails of the backplanes. A plurality of power supplies is connected to the common power rail of the power distribution system. Power taken from any one of the plurality of power supplies is available to any one of the backplanes.
