Intel® Ethernet Server Adapter I350-T4V2

Upgrade your server’s network backbone with the Intel® Ethernet Server Adapter I350-T4V2, a high-density, four-port Gigabit Ethernet PCIe card designed to deliver dependable, scalable connectivity in data centers, rack servers, and enterprise environments. Built on the proven Intel I350 controller, this adapter balances performance and efficiency to keep applications responsive while reducing CPU load. Whether you’re deploying a new server, expanding a virtualization host, or refreshing aging networking hardware, the I350-T4V2 delivers consistent throughput, robust manageability, and easy integration with a wide range of operating systems and hypervisors.

• Four independent 1 Gigabit Ethernet ports provide dedicated bandwidth to each network interface, enabling granular network segmentation, simplified load balancing, and flexible topologies for virtualization, storage, and management networks without sacrificing performance. Each RJ-45 port supports standard Ethernet speeds, auto-negotiation, and reliable copper connections for short- and long-reach deployments.
• PCIe 2.0 x4 host interface ensures ample bandwidth from the system bus to the NIC, supporting high-throughput data transfers and low latency communication with the server’s processor. The PCIe x4 lane configuration helps minimize bottlenecks in multi-VM environments and busy data-center workloads, allowing you to scale up network capacity without sacrificing responsiveness.
• Intelligent offloads and traffic handling reduce CPU overhead and improve overall system efficiency. Features include TCP/IP checksum offload, Large Send Offload (LSO), and Large Receive Offload (LRO), which streamline packet processing, accelerate common server workloads, and free CPU cycles for application tasks. This makes the I350-T4V2 particularly well-suited for database servers, file servers, and virtualization hosts with heavy network traffic.
• Advanced network capabilities support virtualization-ready features and secure, flexible networking. The card supports VLAN tagging (802.1Q) for network segmentation, quality of service (QoS) for traffic prioritization, and robust flow control to maintain stable performance during congestion. Jumbo frames up to 9KB may be supported, enabling more efficient transfers for large data blocks and storage-related workflows.
• Reliability, compatibility, and energy-conscious design. Intel’s Ethernet technologies emphasize dependable operation, broad OS support, and energy-efficient performance (e.g., features like Energy Efficient Ethernet where applicable). The I350-T4V2 is designed for long-term deployment in server environments, delivering steady throughput, predictable latency, and straightforward management across diverse workloads.

How to install Intel® Ethernet Server Adapter I350-T4V2

• Power down the server and unplug it from power. Open the chassis and locate an available PCIe slot that accommodates a full-length PCIe card if needed (verify clearance for your server’s motherboard and expansion slot).
• Remove the slot blank or existing adapter plate as required, then carefully insert the I350-T4V2 into the PCIe x4 slot. Press firmly until the card seats fully and the retention screw brackets align with the chassis slots.
• Secure the card with the screw bracket and reconnect any necessary cables. Attach network cables to the four RJ-45 ports in the desired topology (e.g., management, storage, data, and failover networks).
• Close the chassis, reconnect power, and boot the server. Enter the operating system and install the appropriate Intel driver package or the vendor-provided networking drivers suitable for your OS and hypervisor.
• Configure the network interfaces within the OS or through the host’s management console. Set up VLANs, QoS policies, and any required NIC teaming or bonding to meet your deployment requirements. Verify link status, traffic flow, and performance with diagnostic tools and test traffic to ensure proper operation.

Frequently asked questions

• Q: What is the Intel® I350-T4V2? A: It is a four-port Gigabit Ethernet PCIe network adapter based on the Intel® I350 controller, designed to add reliable 1 Gbps connections to servers and workstations with a PCIe interface for flexible deployment in data centers and enterprise environments.
