Lenovo 4XH7B03848 SR650 V4 8X2.5IN SAS Rear BP Option KIT

Lenovo 4XH7B03848 SR650 V4 8x2.5in SAS Rear Backplane Option Kit

Overview

The 4XH7B03848 is a rear drive backplane option kit for the Lenovo ThinkSystem SR650 V4 rack server, adding eight 2.5-inch SAS hot-swap bays to the rear of the chassis. This kit addresses deployments where front-bay capacity is fully allocated and additional direct-attached storage is needed without migrating to a larger enclosure — a practical path for expanding NVR-adjacent storage, video archive tiers, or high-density compute nodes that accumulate supplemental data drives over time. The SAS interface supports enterprise-class SAS and SATA drives, giving flexibility on drive selection while maintaining the reliability expected in 24/7 server environments. Weighing 10 lb, the kit ships factory-new.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V4 2U rack server. This backplane option is not cross-compatible with earlier SR650 generations (V2, V3) or other ThinkSystem models such as the SR630 or SR650 V2 — confirm the exact chassis generation before ordering. The SAS interface is compatible with both SAS and SATA 2.5-inch drives; SAS expanders or HBA cards already installed in the SR650 V4 must support the additional backplane domain. Verify your server storage configuration and available internal cabling connectors before deploying this kit in a populated chassis.

Installation Notes

Installation requires access to the SR650 V4 rear drive cage assembly and internal SAS/power cabling routed from the system board or installed HBA. Confirm available SAS ports and power connectors on the existing controller before procurement. This is a field-installable server option kit — follow Lenovo ThinkSystem SR650 V4 maintenance documentation for torque specifications and ESD handling procedures. Country of origin is Mexico.
