Lenovo 4XF7A97373 Thinksystem Toolless Slide Rail KIT V4 with 1U CMA

Lenovo 4XF7A97373 Toolless Slide Rail Kit V4 with 1U CMA

Overview

The Lenovo 4XF7A97373 is a toolless slide rail kit designed for 1U rack-mount ThinkSystem servers. The V4 designation indicates compatibility with current-generation ThinkSystem platforms. Bundled with a 1U Cable Management Arm (CMA), this kit addresses two installation tasks at once: secure rack mounting and rear-cable routing — reducing the time spent managing power, data, and management cables behind the chassis. At 10 lb, the combined rail-and-CMA assembly adds minimal load to a loaded rack. Manufactured in Mexico.

Compatibility

Designed for Lenovo ThinkSystem 1U rack servers in the V4 generation. Verify fit against your specific ThinkSystem model's hardware maintenance manual before ordering — Lenovo publishes generation-specific rail compatibility matrices, and V4 rails are not interchangeable with V2 or V3 chassis mounting points. Fits standard EIA-310 19-inch two-post and four-post racks. Confirm minimum rack depth against your ThinkSystem server's rail specification, as 1U slide rails have a minimum extension depth requirement that varies by chassis length. Compatible with the broader Lenovo ThinkSystem server line and integrates into rack server deployments alongside standard rack accessories.

Installation Notes

The toolless design means no screwdriver is required for rail attachment to standard square-hole or round-hole rack posts — pins and latches snap directly into rack unit openings. The included CMA attaches at the rear of the rails and should be routed before final server seating to avoid cable pinch points. Verify that adjacent 1U or 2U chassis do not block CMA swing radius; CMAs require lateral clearance behind the rack uprights. UNSPSC code 43211600 classifies this as rack and rack accessories hardware. For high-density deployments, plan cable management routing before populating adjacent slots — retrofitting CMA cable paths in a full rack is considerably harder than planning the route during initial install.
