Lenovo 4XF7A78619 ST50 V2 Slim ODD Cage Kit
Overview
The Lenovo 4XF7A78619 is a slim optical disc drive (ODD) cage kit designed to add or restore an ODD bay in the ThinkSystem ST50 V2 tower server. If your ST50 V2 was configured without an optical drive at time of purchase, this kit provides the mechanical cage and hardware needed to mount a slim ODD internally — useful when local media boot, software installation, or firmware recovery from physical media is a deployment requirement. The 4XF7A78619 ships from a genuine Lenovo channel source, ensuring proper fitment without modification.
Compatibility
Designed specifically for the Lenovo ThinkSystem ST50 V2 tower server. It is not interchangeable with the original ST50 (V1) or other ThinkSystem tower models such as the ST250 or ST258 — chassis geometry and ODD bay dimensions differ across generations. Verify your server's model badge reads ST50 V2 before ordering. The cage accommodates standard slim-form-factor optical drives (9.5mm height) as used in the ST50 V2 platform; the actual ODD is sold separately and is not included in this kit.
Installation Notes
The cage measures 13.30 × 12.30 × 3.00 in and weighs 1.60 lb — account for adequate clearance inside the chassis before beginning installation. Consult the ST50 V2 server hardware maintenance manual for correct drive bay insertion sequence and any retention clip orientation requirements. No special tooling beyond a standard Torx or Phillips screwdriver is expected for a slim ODD cage installation on this platform, though confirm against the service manual for your specific server revision. Power down and disconnect the server from mains before installing.
