IBM 74Y2205 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y2205 is an I/O backplane, CCIN 2BB9, for the 9117-MMB Power 770 server, sharing its CCIN and functional role with the 74Y2540 backplane handled elsewhere in this batch (both part numbers are listed as alternates for the same 6-slot PCIe x8 board). It provides the physical PCIe expansion slots into which network, storage and Fibre Channel adapters are fitted, sitting between the processor/memory planar and the adapter cards rather than functioning as an adapter itself. Power 770 systems of this generation remain widely deployed in enterprise environments, and a genuine I/O backplane is required whenever the original is damaged, when restoring full adapter-slot capacity, or when rebuilding a chassis from spares. Specifiers should confirm the exact 9117-MMB build and CCIN before ordering, since several visually similar backplanes exist across the Power 770/780 range. Tech-Star (UK-based, shipped worldwide) stocks Power 770 I/O backplanes to support ongoing server maintenance.
