Lenovo 4XF7A89443 ThinkSystem Toolless Slide Rail Kit v2 Enhanced 

Overview

The Lenovo 4XF7A89443 is a ThinkSystem Toolless Slide Rail Kit v2 Enhanced with integrated 1U cable management arm (CMA), designed for mounting Lenovo rack servers in standard data center racks. It enables secure installation while allowing full extension for serviceability without removing the server.

This rail kit supports 1U rack deployments and includes a tool-less design, reducing installation time and minimizing operational overhead during large-scale rollouts. The integrated CMA ensures organized cable routing, preventing strain during sliding operations and improving airflow management.

It is typically deployed in enterprise data centers, colocation racks, and edge infrastructure where frequent maintenance access is required. Compatibility includes multiple Lenovo ThinkSystem servers such as SR630 V2/V3 and SR645 platforms.

Not suitable for non-Lenovo systems or racks requiring fixed rails. Also not intended for higher rack units (2U+) or environments without standard rack mounting infrastructure.
