Lenovo 4XC7A08237

Overview

The Lenovo 4XC7A08237 is a ThinkSystem Ethernet adapter designed to provide high-speed 10 or 25 Gigabit Ethernet connectivity through two SFP28 ports. It features the Broadcom BCM57414 controller and fits into an Open Compute Project mezzanine slot, allowing servers to gain fast network access without using a standard PCIe slot. This adapter supports jumbo frames up to 9600 bytes, enhancing performance for large-packet workloads, and includes Wake-on-LAN for remote power management.

Ideal for data center servers, it supports advanced networking technologies such as RoCE, SDN, NFV, and common virtualization platforms, making it a strong choice for environments that require low latency and high throughput.

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.
