Lenovo 7159BAX

Overview

The Lenovo 7159BAX is a rack-mount Ethernet switch designed to provide data centers and enterprise wiring closets with high-density Gigabit connectivity while maintaining future-proof bandwidth options. This 1U chassis switch features twenty-four RJ-45 ports that automatically negotiate speeds of 10, 100, or 1000 megabits per second, allowing seamless integration of both new servers and legacy devices without manual configuration. Additionally, it includes four open SFP+ slots that support 1 gigabit or 10 gigabit transceivers, enabling flexible fiber or copper uplinks to meet the bandwidth needs of core networks.

Operating at Layer 2, the switch prioritizes fast and predictable packet switching, which is essential for clustered server environments, IP storage traffic, and high-volume web services. Its rear-to-front airflow design aligns with common data center cooling layouts, and the built-in power supply supports redundancy to ensure continuous operation.

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.
