Lenovo 4XH7A87217 SR635 V3 2X2.5INC NVME G4 BP KIT

Lenovo 4XH7A87217 SR635 V3 2x2.5" NVMe Gen4 Backplane Kit

Overview

The Lenovo 4XH7A87217 is a two-bay 2.5-inch NVMe Gen 4 backplane kit engineered for the ThinkSystem SR635 V3 rack server. If you're expanding local NVMe storage capacity on an SR635 V3 — whether for high-throughput workloads, edge computing, or surveillance recording infrastructure — this kit provides the physical backplane hardware required to add or replace the drive bay assembly. NVMe Gen 4 connectivity doubles the theoretical bandwidth ceiling versus Gen 3, which matters when multiple drives are operating concurrently under sustained write loads.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR635 V3 platform. This backplane supports 2.5-inch NVMe storage drives in a two-bay configuration. Verify your SR635 V3 chassis bay slot availability and existing backplane layout before ordering — the SR635 V3 supports multiple storage configurations and not every chassis ships with all bays populated. This kit is not cross-compatible with SR635 (non-V3), SR645, or other ThinkSystem generations without explicit Lenovo configuration guidance.

Installation Notes

Installation requires partial disassembly of the SR635 V3 chassis to seat the backplane into the designated drive cage. Follow Lenovo's ThinkSystem SR635 V3 Maintenance Manual for backplane replacement procedures — improper seating of NVMe signal connectors can prevent drive enumeration at POST. Weighing 10 lb, the kit includes the backplane assembly; confirm your chassis configuration map matches the 2x2.5-inch bay layout this unit occupies. Country of origin: Mexico.
