Lenovo 4XF7A99129 Thinksystem Toolless Stab-in Slide Rail KIT V3

Lenovo 4XF7A99129 ThinkSystem Toolless Stab-in Slide Rail Kit V3

Overview

The Lenovo 4XF7A99129 is a tool-free slide rail kit designed for mounting ThinkSystem V3 servers into standard equipment racks. The stab-in mechanism eliminates the need for loose screws or extra tooling during rail installation — a practical advantage when racking multiple units in a data center or server room where install speed and repeatability matter. At 10 lb, the kit is appropriately weighted for the structural function it serves. Country of origin is Mexico.

Compatibility

This rail kit is designed for the Lenovo ThinkSystem V3 server generation. Verify your specific ThinkSystem server model against Lenovo's compatibility matrix before ordering — rail kits are generation-specific and not interchangeable across V1, V2, and V3 chassis. Confirm your rack's post type (square-hole, round-hole, or threaded) is supported by this stab-in design prior to installation.

Installation Notes

The stab-in design requires no separate fasteners for rail-to-rack attachment, reducing installation time and the risk of dropped hardware in live rack environments. Ensure rack depth falls within the supported range for the ThinkSystem V3 rail specification before committing the server to the rail set. Full installation guidance is available in the ThinkSystem V3 server hardware maintenance manual from Lenovo.
