IBM 45D8590 server / storage / networking hardware Server Hardware / Parts

The IBM 45D8590 is a midplane, listed on the supplier record as 50AA T24 MIDPLANE. The midplane is the backbone of an IBM cage or drawer, carrying the connectors that processor books, adapters, power assemblies and cooling plug into, and the routing between them. It is replaced far less often than the cards around it, but when it is, the part has to match the enclosure exactly. Tell us the machine type and model and we will verify the board we hold against it.

IBM builds its large frame systems, the System z mainframes and the high end Power servers that share their packaging, around a bulk power subsystem rather than around individual power supplies. Mains comes in at the bulk power enclosure, is regulated and controlled there, and is distributed through the frame to converter assemblies at each book and drawer. Blowers, motor drive assemblies and, on the liquid cooled models, refrigeration or water cooling units hold the processor complex in its thermal envelope. Every one of those is a field replaceable unit.

Let us know which IBM system this is destined for and we will verify the unit in stock against your requirement first. Tech-Star (UK-based, shipped worldwide) sources and supplies IBM hardware to order. Get in touch with our sales team for availability and a price.
