Lenovo 4M17A80598 ST250 3.5 4BAY SS Bracket Plate KIT V2

Lenovo 4M17A80598 ST250 3.5-Inch 4-Bay SSD Bracket Plate Kit V2

Overview

The Lenovo 4M17A80598 is a second-generation bracket plate kit designed to populate 3.5-inch drive bays with 2.5-inch solid-state drives in the ST250 tower server. If your ST250 ships with open 3.5-inch bays but your storage plan calls for 2.5-inch SSDs, this kit bridges the mechanical gap — no improvised mounting, no voided chassis fitment. The V2 revision aligns with current ST250 production tolerances. At 2 lb, the hardware is substantial enough to confirm genuine metal construction rather than plastic adapter trays.

Compatibility

Designed for the Lenovo ThinkSystem ST250 tower server. This kit addresses the 3.5-inch server storage accessory bays on that platform specifically — do not assume cross-compatibility with ST50, ST550, or other ThinkSystem tower variants without verifying Lenovo's configurator for those chassis. If you are specifying a network video recorder build on ST250 hardware with SSD-based storage, confirm your target bay count against the chassis's populated vs. unpopulated bay map before ordering. Four bays are addressed by this single kit, making it the correct quantity for a full 4-bay SSD conversion in one order.

Installation Notes

Installation follows standard Lenovo tool-less or screw-retained drive tray procedures for the ST250 chassis — consult the ST250 Hardware Maintenance Manual for torque specs and bay sequencing. Populate bays in the order Lenovo specifies to maintain airflow balance across the drive cage. Verify firmware and RAID controller compatibility with your chosen SSD form factor before committing to a configuration.
