IBM 73Y9590 server / storage / networking hardware Server Hardware / Parts

The IBM 73Y9590 is a BPC, the bulk power controller from an IBM frame power subsystem, listed as BPC. It supervises the regulators and distribution assemblies that feed the rest of the machine, handles power sequencing, and passes power and environmental status back to the service network. Two are normally fitted so that control survives a single failure. Which controller is correct depends on the machine type and the generation of the power enclosure.

System z mainframes and the largest Power servers are still running production workloads in banking, insurance, government and manufacturing. IBM designed them to be serviced part by part, with hot pluggable power, cooling and I/O units held in redundant configurations so that a single failure is a scheduled repair rather than an outage. Sourcing the correct unit for the machine type in question is what keeps that model working.

If you can give us the machine type and model, or the feature code you are matching, we will confirm what we hold before you commit. Tech-Star is UK-based and ships worldwide. Contact our sales team for stock, condition details and pricing on this IBM part.
