Lenovo 4XH7B03852 SR650 V4 8X3.5IN Sas/sata BP Option KIT

Lenovo 4XH7B03852 SR650 V4 8-Bay 3.5in SAS/SATA Backplane Option Kit

Overview

The Lenovo 4XH7B03852 is a factory-configured backplane option kit for the ThinkSystem SR650 V4 rack server, enabling an 8-bay 3.5-inch drive configuration with dual SAS/SATA interface support. If your SR650 V4 deployment requires bulk spinning-disk capacity — high-density surveillance recording, long-retention NAS workloads, or tiered storage architectures — this kit provides the physical backplane infrastructure to support that drive count. The 4XH7B03852 ships at 10 lb, reflecting integrated backplane hardware rather than a simple cable accessory.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V4 platform. The 8x3.5-inch bay configuration targets deployments that require large-format spinning drives (4TB–20TB+ SAS or SATA HDDs) rather than the 2.5-inch SFF NVMe/SAS SSD configurations. Verify your SR650 V4 chassis variant and existing backplane topology before ordering — the SR650 V4 supports multiple drive bay configurations and not all chassis configurations accept this kit without corresponding hardware preparation. Cross-reference against Lenovo's SR650 V4 server storage configuration guide to confirm bay slot availability and controller compatibility. SAS/SATA dual-interface means the backplane will accept either drive type, giving you flexibility to mix HDD tiers or standardize on one interface without re-cabling. For storage-intensive applications such as network video recorders or high-capacity archive nodes, pairing this backplane with a qualified RAID controller is required — the backplane itself is passive and does not provide RAID functionality. Country of origin: MX.

Installation Notes

Installation is performed inside the SR650 V4 chassis with the server powered down and disconnected. This is a field-installable option kit intended for qualified server technicians — confirm your maintenance agreement terms before self-installing if the server is under an active service contract. The kit weighs 10 lb; plan for two-person installation when working in a live rack environment. SAS and SATA signal cabling to the host bus adapter or onboard controller must be routed and secured after backplane seating. No drive population is included — procure SAS or SATA 3.5-inch drives separately sized to your retention requirements.
