Description

Lenovo 4XF7A81461 ST250 8-Bay 2.5" Hot-Swap SAS/SATA Backplane Kit

Overview

The Lenovo 4XF7A81461 is a factory-new backplane kit that converts or equips the ST250 server with eight 2.5-inch hot-swap drive bays over dual-protocol SAS/SATA connectivity. Hot-swap support means drive replacements or capacity additions happen without taking the server offline — a practical requirement for environments running storage-intensive workloads like NVR recording, database servers, or file services where downtime directly affects operations. This kit delivers the mechanical and electrical infrastructure needed to populate the ST250's drive cage with enterprise-grade 2.5-inch HDDs or SSDs.

Compatibility

The 4XF7A81461 is designed for the Lenovo ThinkSystem ST250 tower server. It provides 8x 2.5-inch hot-swap bays with SAS and SATA interface support — meaning you can mix SAS HDDs, SATA HDDs, and SATA SSDs within the same backplane depending on your storage controller configuration. Confirm your ST250's HBA or RAID adapter supports the drive types you intend to install; SAS drives require a SAS-capable controller, while SATA-only controllers cannot address SAS drives regardless of backplane support. Before ordering, verify the ST250 chassis revision and current drive bay configuration against Lenovo's compatibility matrix to ensure this backplane kit is the correct fit for your unit.

Installation Notes

At 4.90 lb and 16.30 × 7.30 × 13.40 inches, this is a substantial assembly — plan for two-person handling during chassis integration. Installation is performed inside the ST250 tower with the system powered down; the hot-swap capability applies to drive operations post-installation, not to the backplane itself. Follow Lenovo's ST250 service documentation for torque specs on retention hardware and proper cable routing to the storage controller.
