The Lenovo 4XH7A82916 is a middle backplane kit designed to expand internal drive capacity on the ThinkSystem SR650 V3 rack server. It adds four 3.5-inch SAS/SATA drive bays in the middle bay position — the correct option when a base configuration ships without this section populated and the workload demands additional spinning or solid-state storage without consuming external enclosure space or PCIe slots. At 10 lb, it is a substantial mechanical assembly intended for qualified server technicians performing a planned capacity expansion.
This kit is designed specifically for the Lenovo ThinkSystem SR650 V3 server platform. It is not interchangeable with SR650 V2, SR650 Gen 1, or other SR-series chassis — backplane form factors and connector pinouts differ across generations. Confirm your chassis model and existing bay configuration against Lenovo's SR650 V3 hardware maintenance manual before ordering. The backplane supports both SAS and SATA 3.5-inch drives, giving flexibility to mix enterprise spinning drives with SATA SSDs in the same cage if the connected HBA or RAID controller supports mixed-protocol operation.
Installation requires access to the SR650 V3 interior with the chassis fully powered down and racked out. This is a server storage component replacement/addition — follow ESD precautions and consult the SR650 V3 hardware maintenance guide for bay cage alignment, cable routing to the onboard storage controller or HBA card, and torque specifications on retaining screws. Country of origin is Mexico (MX). UNSPSC code 43211600 classifies this as a computer storage device component.
