Lenovo 4XH7A61125 SR630 V2 Rear 2X2.5 Sas/sata BP KIT V2

Lenovo 4XH7A61125 Rear 2x2.5 SAS/SATA Backplane Kit for SR630 V2

Overview

The Lenovo 4XH7A61125 is a rear drive backplane kit that adds two 2.5-inch SAS/SATA drive bays to the back of a ThinkSystem SR630 V2 rack server. If your SR630 V2 deployment needs additional storage capacity beyond the front-bay configuration — common in database, surveillance NVR, or dense virtualization workloads — this kit provides the physical backplane and mounting hardware to populate the rear chassis bays without modifying the front storage layout. The result is a clean, factory-integrated expansion rather than an external add-on.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR630 V2 server platform. The rear bay kit is chassis-specific and not interchangeable with SR630 (V1), SR650, SR650 V2, or other ThinkSystem 1U/2U platforms — verify your server generation before ordering. Supports both SAS and SATA 2.5-inch drives, so existing SAS HDDs, SATA SSDs, or NVMe-to-SATA adapters in your environment can populate these bays without a separate adapter. For full drive compatibility, cross-reference against the SR630 V2 server components compatibility matrix published by Lenovo.

Installation Notes

The kit ships at 2.40 lb with overall package dimensions of 16.00 x 13.50 x 3.30 inches — plan rack clearance and staging space accordingly before beginning installation. Rear backplane installation on the SR630 V2 requires pulling the server from the rack; no hot-swap backplane replacement is supported during operation. Consult the SR630 V2 Hardware Maintenance Guide for backplane connector seating torque and cable routing specifics before installation. No additional power supply upgrade is documented in the available evidence for this kit alone, but confirm total drive count against your PSU budget when populating both front and rear bays simultaneously.
