Add high-density 1 GbE copper connectivity to compatible servers with the Axiom 49Y4240-AX quad-port RJ45 adapter. Built for PCI Express 2.1 x4 systems, it gives infrastructure teams four Ethernet ports in a single slot, helping conserve expansion space while supporting practical network segmentation, redundancy planning, or multiple service connections. This adapter is a strong fit where 1 GbE remains the right economic and operational choice. The plug-in card form factor keeps installation simple in supported servers, while the RJ45 interface preserves broad compatibility with standard copper cabling. For teams managing mixed environments, the quad-port layout can reduce the number of add-in cards required per server, simplifying inventory, deployment, and maintenance. Axiom backs the adapter with a 3-year limited warranty, adding lifecycle confidence for enterprise purchasing. When the goal is to increase port count without changing the network tier, this model delivers the density and compatibility that matter.
