Consolidate four wired connections into one adapter and keep your server slots working harder. The AddOn 49Y4240-AO delivers 10/100/1000 Mbps Ethernet across four RJ-45 ports, giving infrastructure teams a practical way to add density without adding unnecessary complexity. It is a strong fit for servers that need multiple LAN connections, segmented traffic paths, or dedicated management and application links. Built on a PCI Express 2.0 x4 host interface and powered by the Intel 82580 chipset, this adapter is designed for environments that value predictable copper networking and broad compatibility. The quad-port layout helps reduce card count in systems where expansion space is limited, while the plug-in card form factor keeps installation straightforward in standard server chassis. For teams comparing single-port or consumer-grade adapters, this model stands out by combining four ports, server-oriented design, and a proven Intel controller. That combination makes it easier to justify the investment when uptime, port density, and clean rack integration matter more than the lowest entry price.
