The IBM 39Y9168 is a copper pass-through module cable designed for IBM eServer BladeCenter environments. This network cable facilitates high-speed connectivity between blade servers and external switching infrastructure within BladeCenter chassis systems, supporting standard Ethernet transmission rates. The pass-through design allows network traffic to bypass internal switching modules when direct external connectivity is required, reducing latency and simplifying fabric management in blade deployments.Compatible with IBM BladeCenter H and earlier chassis generations, the 39Y9168 integrates with pass-through modules to provide flexible network topology options for virtualized and high-density computing environments. Typical applications include data center blade server consolidation, hypervisor deployments, and network-intensive workloads requiring direct external switch connectivity. This refurbished unit has been tested and guaranteed to meet original IBM specifications, available via quote.
