Lenovo 4C57A82404 ST650 V3 3.5IN Anybay 4-BAY BP KIT

Lenovo 4C57A82404 ST650 V3 3.5-Inch Anybay 4-Bay Backplane Kit

Overview

The Lenovo 4C57A82404 is a 3.5-inch Anybay 4-bay backplane kit designed for the ThinkSystem ST650 V3 tower server. Anybay backplane architecture supports mixed drive populations — NVMe, SAS, and SATA within the same bay set — so you can install the drive types your workload demands without reconfiguring the chassis or sourcing multiple backplane variants. At 10 lb, this is a hardware-only storage expansion component intended for integrators adding bay capacity or replacing a backplane during server build-out.

Compatibility

Designed specifically for the Lenovo ThinkSystem ST650 V3 tower server. The Anybay designation means the backplane supports NVMe, SAS, and SATA server storage drives interchangeably across its four 3.5-inch bays — a meaningful advantage when mixing SAS HDDs with NVMe SSDs in the same chassis. Verify your ST650 V3 configuration guide for slot position and cable routing requirements before ordering; Lenovo server components are chassis-revision specific and the ST650 V3 designation is the supported platform. This kit is not compatible with ST650 V2 or earlier ST650 revisions.

Installation Notes

Installation requires access to the ST650 V3 internal chassis bay cage. Cable routing from the backplane to the system board follows Lenovo's prescribed signal and power harness map for the ST650 V3 — refer to the server's hardware maintenance manual for connector assignments before seating the backplane. Incorrect cable routing on Anybay backplanes can prevent NVMe drive enumeration even when SAS/SATA drives initialize normally, so verify harness paths before first power-on. Country of origin: Mexico.
