Lenovo ThinkSystem 1U CMA Upgrade Kit 4M17A07276 | Rail Kit, Server

Keep rear cabling under control when servers slide out for service. Lenovo's ThinkSystem 1U CMA Upgrade Kit for Screw-in Slide Rail adds cable management support to compatible ThinkSystem systems, helping data center teams maintain orderly routing without sacrificing access to the chassis. Designed for Lenovo ThinkSystem SR530, 7X07, and 7X08 platforms, this upgrade kit is intended for environments where serviceability and cable discipline matter. By guiding cables through movement, it helps reduce connector stress, limits accidental disconnections, and supports cleaner airflow around the rear of the rack. For infrastructure teams standardizing on Lenovo hardware, this kit is a practical add-on that improves maintenance workflow without changing the server footprint. It is a focused accessory for installations that need dependable cable control on screw-in slide rail configurations, especially where repeated service events make cable wear and rack clutter a real operational cost.
