Preservation and installation notes
SR650 differs from SR650 V2/V3; firmware, backplane and riser are generation-specific. Identify machine type and riser/backplane assembly before part substitution.
Lenovo-specific risers, AnyBay backplanes, adapters and rails; board/slot/drive combinations vary. PCIe GPU support depends on riser and PSU options.
- Capture the complete model/SKU, serial/date label, board assembly and bay/backplane/riser identifiers before disassembly; keep matched screws, trays, carriers, feet and cables with the case.
- Check the cited manual's specific build option before transferring hardware. Published maximum GPU, drive, fan or radiator capacity may not be simultaneous when a removable cage or alternative riser occupies that volume.
- For rack and vintage systems, preserve the exact rails, shields, doors, brackets and model-specific safety instructions; do not infer compatibility from a familiar brand or physical connector shape.
