IBM 74Y1142 server / storage / networking hardware Server Hardware / Parts

The IBM 74Y1142 is a PCI I/O backplane, CCIN 50A2, fitted inside the FC5802/FC5877 12X PCIe I/O expansion drawer used with Power6 and Power7 systems. It is the internal card cage backplane that the drawer’s PCIe adapters plug into, distinct from the drawer’s own enclosure (handled elsewhere in this batch as feature code 5877) or the 12X DDR cabling that links the drawer back to the central electronics complex. Expansion drawers of this generation remain in service across many established Power Systems deployments running AIX, IBM i and Linux, adding PCIe adapter slots beyond a server’s built-in capacity, and a genuine backplane replacement is required whenever the original is damaged or when restoring the drawer’s full slot capacity. Specifiers should confirm the exact 5802/5877 drawer generation before ordering. Tech-Star (UK-based, shipped worldwide) supplies the 74Y1142 for engineers maintaining Power Systems I/O expansion drawers.
