IBM i Networking and Connectivity Overview
Networking hardware for IBM i spans the internal I/O adapters that give a Power server its network presence and the surrounding switches and cabling that connect terminals, printers, and workstations back to it. Buyers in this category are usually solving a specific connectivity gap rather than shopping generically.
That gap is often an aging network adapter approaching end of support, a switch that no longer has capacity for added IP-attached terminals, or a connectivity change tied to a server upgrade or relocation project.
