Axiom PCIE-4RJ45-AX quad-port PCIe x4 network card

Quad-port copper NIC for servers

The Axiom PCIE-4RJ45-AX adds four RJ-45 ports over a single PCI Express 2.1 x4 slot. It targets administrators who need multiple Gigabit links in a low-profile server chassis without occupying extra expansion slots.

Four 10/100/1000Base-T links on twisted pair

Each port negotiates 10, 100 or 1000 Mbps on standard copper cabling. The x4 host interface provides enough bandwidth for simultaneous full-duplex traffic on all four ports, while the plug-in card form factor fits 5.9-inch by 2.2-inch spaces.

Replaces four single-port adapters in one slot

Consolidating four connections onto one card frees three expansion slots for storage controllers or additional I/O. The jump makes sense when a server has limited PCIe slots but needs multiple segregated network segments or link-aggregation groups.
