Lenovo ThinkServer I350-T4 PCIe Adapter | 4-Port Gigabit Ethernet

Add high-density copper networking to a Lenovo server without consuming extra chassis space. The ThinkServer I350-T4 PCIe adapter delivers four 1 GbE ports through a PCIe host interface, giving infrastructure teams a practical way to segment traffic, increase port availability, and simplify server-side cabling. Built around the Intel I350 family, this adapter is well suited to production environments where stable Ethernet performance matters more than headline speed. It fits neatly into server expansion planning for virtualization hosts, storage gateways, backup targets, and application servers that need multiple physical NICs for redundancy or traffic separation. For teams standardizing on Lenovo ThinkServer hardware, the I350-T4 offers a clean upgrade path from onboard networking. It supports copper-based Base-T connectivity, making it easy to integrate into existing switch infrastructure without transceivers or fiber planning. The four-port design also helps reduce the need for additional adapters in dense deployments, which can lower complexity in rack builds and improve serviceability. When you need more ports, more control, and a server-grade Ethernet adapter that aligns with enterprise deployment patterns, this model delivers the right balance of capacity and practicality.
