IBM 45D1135 server / storage / networking hardware Server Hardware / Parts

The IBM 45D1135 is a Bulk Power Distributor, BPD-EZ variant, part of the Bulk Power Assembly subsystem IBM uses across its Power Systems and System z frame families. The BPD sits between the Bulk Power Controllers and the rest of the frame’s power infrastructure, distributing regulated DC power out to the processor, I/O and cooling subsystems rather than converting or controlling it directly; that distribution role is what distinguishes a BPD from a BPC or a DCA in the same subsystem. The ‘EZ’ suffix marks this as a variant of the standard BPD used on a specific frame generation, consistent with the equivalent BPC-EZ and BPD-GRY parts documented for related frame types, though the exact host frame for this specific FRU could not be independently pinned down. Genuine BPD spares are needed when a distribution fault takes out power to part of a frame or when restoring N+1 redundancy after a bulk-power component failure. Tech-Star (UK-based, shipped worldwide) supplies Bulk Power Assembly components to support ongoing frame maintenance.
