Lenovo x3650/x3750 M4 8x SFF Backplane — 8x SFF | Lenovo, Backplane, Server

Maintain storage availability in Lenovo x3650 and x3750 M4 platforms by installing a factory‑matched 8x SFF backplane. This assembly preserves the chassis’ hot‑swap bay layout, drive sled alignment, and internal signal routing for SAS/SATA drives, enabling predictable replacements during field service. Supplied under Lenovo DCG Sourcing (MPN 46W9187), the backplane helps standardize spare parts and reduces procurement risk compared with mixed third‑party backplanes. Use it when restoring degraded arrays, staging standardized spares across multiple racks, or performing preventive maintenance on production clusters. Because it matches the OEM mechanical and electrical interfaces, the backplane minimizes rework and ensures compatibility with existing drive trays and cabling harnesses used in the x3650/x3750 M4 family.
