Lenovo 4XF7A79661 ST50 V2 NVME M.2 Bracket KIT

Lenovo 4XF7A79661 NVMe M.2 Bracket Kit

Overview

The Lenovo 4XF7A79661 is an M.2 bracket kit designed to mechanically seat and secure an NVMe M.2 drive inside a compatible Lenovo server chassis. If you're adding NVMe-based storage to a ThinkSystem ST50 V2 without the bracket pre-installed, this kit is the missing hardware component — without it, the M.2 card has no anchor point and cannot be properly installed. The 4XF7A79661 addresses a straightforward but critical gap: M.2 drives are not self-supporting in tower server bays and require a chassis-specific bracket to align and retain the module at the correct angle.

Compatibility

This bracket kit is designed for the Lenovo ThinkSystem ST50 V2 tower server. Verify your specific ST50 V2 configuration and system board revision against Lenovo's compatibility matrix before ordering — M.2 bracket fitment is chassis-generation-specific and the ST50 V2 is distinct from the original ST50. Do not assume compatibility with other ThinkSystem tower or rack models without confirming against the server's server accessory options list.

Installation Notes

The kit ships in a standard retail accessory package measuring 9.70 x 6.00 x 2.30 in and weighs 0.20 lb — light enough that shipping cost is negligible. Installation involves seating the bracket in the designated M.2 slot location on the system board, inserting the M.2 NVMe drive at the specified angle, and fastening the retention screw. No special tooling beyond a standard Philips screwdriver is indicated. Consult the ST50 V2 hardware maintenance manual for slot location, supported M.2 form factors (2242, 2280), and drive enablement steps in UEFI — the bracket alone does not configure the drive; firmware recognition must be confirmed post-install.
