IBM 41U8055 server / storage / networking hardware Server Hardware / Parts

The IBM 41U8055 is a midplane assembly, recorded here as midplane asm. A midplane is the passive board that everything else in a drawer or cage plugs into: processor and memory cards from one side, power and I/O from the other, with the signal and power routing between them built into the board. Because it defines the mechanical and electrical layout of the enclosure, a midplane belongs to one specific machine and drawer type. Confirm the machine type and model before ordering.

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.
