The power subsystem of a variable sized data processing system is controlled by a power fault/controller (PFC) including a protect card which communicates with sense cards dedicated to each power supply in the data processing system. The technique allows easy field expandability of the data processing system with associated additional power supplies. Input AC power fault warning is realized to provide for a sequenced shut-down of the system. The technique also provides for the storage of multiple cycles of fault data and is transparent to the power supply technology used.
