Lenovo 4XH7A87216 SR635 V3 2X2.5SAS G4BP KIT

Lenovo 4XH7A87216 SR635 V3 2x2.5" SAS Gen4 Backplane Kit

Overview

The Lenovo 4XH7A87216 is a 2x2.5" SAS Gen4 backplane (G4BP) drive bay kit designed for the Lenovo ThinkSystem SR635 V3 server platform. If you're expanding or replacing the front drive bay assembly on an SR635 V3 — whether to add SAS storage capacity or restore a failed backplane — this kit provides the correct factory-configured component for that chassis. The 4XH7A87216 is sourced factory-new with no grey-market substitutions.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR635 V3 rack server. The G4BP designation confirms Gen4 backplane signaling — do not substitute a Gen3 backplane, as the connector and signal specifications differ. This kit supports 2x 2.5" small form factor SAS drives. Verify your SR635 V3 configuration order form or existing chassis bay layout before ordering to confirm this is the correct backplane position and drive count for your build. For broader server storage components, confirm chassis revision compatibility with Lenovo's SR635 V3 product guide.

Installation Notes

Weighs 10.00 lb — account for this during chassis work, particularly in dense rack environments where the server may need to be partially extended on rail slides. Manufactured in Mexico. UNSPSC commodity code 43211600 (computer storage). Follow Lenovo's SR635 V3 hardware maintenance guide for backplane seating, SAS cable routing, and torque specifications — improper seating of the backplane connector is the most common cause of drive non-detection post-installation.
