Lenovo 4XC7A62580

Overview

The Lenovo 4XC7A62580 is a dual-port 10 or 25 Gigabit Ethernet adapter designed for high-performance server environments. It features two SFP28 ports and a PCIe 4.0 x8 host interface, delivering consistent throughput and efficient CPU utilization through advanced hardware offloads. This card supports RDMA over Converged Ethernet (RoCE v2) and NVMe over Fabrics, accelerating storage and data movement in data centers that require fast east-west traffic.

Its compatibility with virtualization technologies like SR-IOV and Open vSwitch, along with support for network overlays such as VXLAN, NVGRE, and GENEVE, makes it well suited for cloud deployments and multi-tenant networks. The included low-profile and full-height brackets ensure easy installation across various server chassis, while PXE boot capability simplifies bare-metal provisioning.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
