Lenovo 4XF7A79662 ST50 V2 3.5 Drive BAY 3 Cage KIT

Lenovo 4XF7A79662 ST50 V2 3.5" Drive Bay 3 Cage Kit

Overview

The Lenovo 4XF7A79662 is a factory-designed drive bay cage kit that adds a third 3.5" storage bay to the ThinkSystem ST50 V2 tower server. If your ST50 V2 is running at its base drive bay count and you need to expand direct-attached storage without moving to a larger chassis or external enclosure, this kit is the correct path. It fits the existing internal bay infrastructure of the ST50 V2 — no third-party brackets, no workarounds. Dimensions are 13.20 x 12.20 x 2.90 in and the kit weighs 1.05 lb, consistent with a sheet-metal cage and retention hardware set.

Compatibility

Designed specifically for the Lenovo ThinkSystem ST50 V2 tower server drive bay kits. This cage occupies the third 3.5" drive bay position in that chassis. It is not a universal fit — do not use with ST50 (Gen 1), ST250, ST550, or other ThinkSystem tower models. Confirm your server is the ST50 V2 variant before ordering; the Gen 1 ST50 uses a different internal layout and this cage will not seat correctly.

Installation Notes

Installation is an internal chassis operation requiring the ST50 V2 to be powered down and the side panel removed. The cage slides into the designated Bay 3 slot in the drive cage area and secures using the server's existing retention points — no additional screws or tools beyond a standard Phillips driver are expected for a cage kit of this type. Once seated, 3.5" SATA or SAS drives (depending on your HBA/backplane configuration) can be installed into the cage. Verify your storage controller supports the additional bay before populating it. This is a server storage expansion component — factory-new, genuine Lenovo part sourced through channel-direct distribution.
