IBM 44P1221 server / storage / networking hardware Server Hardware / Parts

The IBM 44P1221 is a Bulk Power Controller (BPC) Assembly, CCIN RGA1, built for the IBM 7040-61R pSeries server, the POWER4-based p690 ‘Regatta’ frame. It is documented consistently across multiple specialist IBM hardware resellers as this exact function, CCIN and host platform, and sits at the top of the Bulk Power Assembly hierarchy, controlling and sequencing the frame’s overall power-on/power-off logic and coordinating the Bulk Power Distributors and DCAs beneath it rather than converting power itself. Genuine BPC spares of this CCIN are needed when a p690 frame develops a power-sequencing or controller fault, or when restoring the frame’s N+1 controller redundancy after a failure; a BPC fault, unlike a single DCA or PSU failure, can affect the whole frame’s ability to power on. Tech-Star (UK-based, shipped worldwide) supplies IBM Power Systems components to support ongoing legacy frame maintenance.
