Description

Overview

The Lenovo 4M27A67042 is a QSFP28 transceiver module designed to provide a reliable 100 Gigabit Ethernet connection for Lenovo networking and storage systems. It supports 100GBase-SR4 technology, enabling data transfer speeds up to 100 Gbps over multimode optical fiber distances of up to 328 feet. This module is ideal for enhancing bandwidth between servers, top-of-rack switches, and storage arrays within data centers.

Installation is simple, as the module fits into any compatible QSFP28 port and begins transmitting data immediately. Lenovo has qualified this transceiver for use with ThinkSystem Mellanox ConnectX-6 HDR InfiniBand adapters and DM7100F and DM7100H 4U storage chassis, ensuring tested compatibility and reliable performance.

Key features

Product warranty

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.
