IBM 74Y2540 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y2540 is an I/O backplane with six PCIe x8 slots, CCIN 2BB9, for the 9117-MMB Power 770 server (the same backplane family also carries the alternate part numbers 74Y2205, 74Y2684 and 01DH376 among others). It provides the physical PCIe expansion slots into which network, storage and Fibre Channel adapters are fitted, sitting between the system planar and the adapter cards themselves rather than being an adapter in its own right. Power 770 systems of this generation remain widely deployed in enterprise environments running AIX, IBM i and Linux, 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.
