Lenovo Intel I350-T4 4-Port Ethernet Expansion Card

The Lenovo Intel I350-T4 4-Port Ethernet Expansion Card is a dependable, cost-efficient solution for expanding your network capacity by four high-performance Gigabit Ethernet ports through a single PCI Express slot. Built around the Intel I350 chipset, this quad-port NIC blends solid throughput, low CPU overhead, and flexible networking features to support demanding server, workstation, and storage environments. Whether you’re adding additional management interfaces, creating dedicated VM networks, or separating traffic for security and performance, the I350-T4 card delivers reliable connectivity, easy deployment, and scalable performance in a compact, Lenovo-optimized package. With broad compatibility, robust virtualization support, and energy-conscious design, it’s a smart upgrade for any system that needs more bandwidth without overhauling your infrastructure.

• Quad-port networking for dense deployments: expand network capacity by adding four RJ-45 ports on a single PCIe card, enabling multi-network configurations without occupying multiple PCIe slots.
• Intel I350 chipset with hardware offloads: enjoy improved throughput and reduced CPU utilization thanks to advanced offloads for TCP/IP, UDP checksum, Large Send/Receive, and VLAN tagging—ideal for virtualization, file services, and high-traffic workloads.
• Versatile virtualization and server-ready features: designed to support NIC teaming (Link Aggregation), VLAN segmentation, and multiple virtual networks, making it a perfect fit for hypervisors (VMware/Hyper-V/KVM), storage networks, and high-availability setups.
• Energy efficiency and reliable operation: built with features like Energy Efficient Ethernet (EEE) and Wake-on-LAN, helping you manage power consumption in dense deployments while maintaining quick network access when needed.
• Broad compatibility and flexible mounting: compatible with Lenovo systems and a wide range of operating systems, with both standard full-height and low-profile brackets available to fit compact or traditional chassis configurations.

How to install Lenovo Intel I350-T4 4-Port Ethernet Expansion Card

• Power down your system, unplug it from the power source, and remove the chassis cover to access the motherboard.
• Identify an available PCI Express slot (preferably PCIe x4 or larger) on the motherboard and remove the corresponding slot cover.
• Insert the Lenovo Intel I350-T4 card firmly into the PCIe slot until it is fully seated; secure the bracket with a screw to the chassis for stability.
• Power on the system and boot into the operating system; install the recommended drivers from Lenovo or Intel to enable full functionality of all four ports.
• Configure the network interfaces in your operating system or hypervisor: assign IPs, set up NIC teaming or VLANs as needed, and verify connectivity with basic tests (ping, file transfer) to ensure proper operation.
• If you plan to use NIC teaming or VLANs, create the desired teams or VLAN interfaces in your OS or virtualization platform, apply the correct security settings, and document the topology for future maintenance.
