Lenovo 00JY940

Overview

The Lenovo 00JY940 is a high-performance network interface card designed to provide two 10GbE connections via SFP+ optical ports. It uses an Intel X710-DA2 ML2 design and connects through a PCI Express 3.0 x8 interface, fitting into a Mezzanine LAN-on-Motherboard Generation 2 slot. This adapter delivers a combined data transfer rate of 20 Gbps, making it well suited for enterprise data centers that require reliable, high-throughput wired networking for virtualized workloads and large data transfers.

Its support for SNMP and RMON protocols allows administrators to monitor link health and network performance remotely, ensuring efficient management of demanding data paths. The SFP+ optical ports are compatible with fiber-based aggregation and top-of-rack switches, aligning with modern server rack configurations.

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.
