Lenovo Network 7159BAX RackSwitch Rack Mountable Ethernet Switch

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.
