Lenovo 4XF7A99130 Toolless Stab-in Slide Rail Kit V3 with 1U CMA

Overview

The Lenovo 4XF7A99130 is a 1U toolless stab-in slide rail kit with integrated cable management arm (CMA) designed for rack-mounted ThinkSystem server deployments. The stab-in design eliminates the need for tools or loose hardware during installation, which cuts rack-population time significantly when you're deploying multiple 1U nodes in a single maintenance window. The bundled 1U CMA keeps power and data cables routed and protected as the server slides in and out for servicing — preventing cable strain and snagging that's common in dense rack environments. At 10 lb, the kit adds minimal overhead to overall rack weight calculations. Country of origin is Mexico.

Compatibility

The 4XF7A99130 is designed for Lenovo ThinkSystem V3 1U server platforms. Verify your specific ThinkSystem model against Lenovo's rack accessory compatibility matrix before ordering — not all V3 chassis share the same rail pocket geometry. Compatible rack enclosures must support standard EIA-310 rail spacing; confirm inner clearance for the CMA when the server is fully extended. This kit is not interchangeable with V1 or V2 rail kits, which use different mounting profiles.

Installation Notes

Stab-in rail installation requires no tools for the rail-to-rack attachment — brackets compress and lock into square-hole or round-hole rack posts without screws. The CMA attaches to the rear of the slide assembly and must be connected to a fixed rack anchor point on one end and to the server chassis on the other; confirm the rear rack-post depth falls within the CMA's articulation range before finalizing rack placement. Route cables through the CMA loops before sliding the server fully into the rack to avoid cable pinching during the first full extension cycle.
