Lenovo 4M17A12094 ST50 Flash Power Module Mechanical KIT

Lenovo 4M17A12094 ST50 Flash Power Module Mechanical Kit

Overview

The Lenovo 4M17A12094 is a mechanical kit designed to install a flash power module in the ThinkSystem ST50 tower server. Flash power modules (sometimes called capacitor-pack or supercap units) protect RAID write-back cache during unexpected power loss — this kit supplies the physical mounting hardware needed to seat and secure that module inside the ST50 chassis. If you're adding or replacing a flash power module in an ST50 build and the retention hardware is missing, worn, or damaged, the 4M17A12094 is the correct replacement assembly.

Compatibility

Designed specifically for the Lenovo ThinkSystem ST50 tower server. This kit addresses the mechanical installation requirement for the ST50's flash power module bay. It is not a universal fit — confirm your chassis is an ST50 before ordering. If you are outfitting a different ThinkSystem platform (ST250, ST550, SR series rack servers), a different mechanical kit is required; consult the Lenovo parts configurator for the correct assembly for those server platforms.

Installation Notes

At 0.40 lb and 9.50 x 5.75 x 2.50 in, the kit ships as a compact assembly. Standard data center hand tools are sufficient for installation — no special torque or wiring requirements are documented for this mechanical kit beyond following the ST50 Hardware Maintenance Manual procedure for flash power module installation. Ensure the server is powered down and disconnected before seating the module and securing the bracket.
