Lenovo 4XF7A78620 ST50 V2/ST250 V2 Rack Mount KIT

Lenovo 4XF7A78620 Tower-to-Rack Conversion Kit

Overview

The Lenovo 4XF7A78620 is a rack mount conversion kit designed to install Lenovo tower servers into a standard 19-inch equipment rack. If you're consolidating infrastructure into a rack enclosure — a server room, a wiring closet, or a rack-mounted surveillance or IT stack — this kit eliminates the need to source a rack-native server model. The 4XF7A78620 weighs 19.00 lb and measures 25.10 × 4.50 × 24.30 in (L × W × H), placing it in the range of a 2U rack footprint. Converting a tower to rack-mount also simplifies cable management and positions the server for standard rack power distribution and airflow.

Compatibility

This kit is specifically designed for the Lenovo ST50 V2 and ST250 V2 tower servers. It is not a universal rack rail — do not order this for other Lenovo ThinkSystem tower models (ST550, ST650 V2, or earlier ST50/ST250 V1 variants) without confirming fitment against Lenovo's compatibility matrix. If you are deploying either of these servers into a rack enclosure, verify your rack's usable depth accommodates the 25.10-inch length of the mounted assembly before ordering.

Installation Notes

The assembled dimensions — 25.10 in depth × 4.50 in width × 24.30 in height — indicate this occupies significant rack real estate both vertically and in depth. Confirm your rack's interior depth (typically 28–32 in for full-depth racks; shallow-depth racks at 20–24 in will not clear this kit). At 19.00 lb for the kit alone, factor total server weight when planning rack power distribution and structural load across your rack's mounting rails. No tool specifications or torque values are documented in the available evidence — follow Lenovo's installation guide shipped with the kit for fastener requirements.
