Compatibility & preservation notes
Dell-specific board, PSU, risers and rails. PCIe card height/length depends on chosen riser and slot position.
Use lift/2-person handling. Keep drive carriers numbered, label risers and record backplane/controller mapping before service; follow manual power precautions.
- Record the complete model/SKU, serial/date label, board and bay/backplane identifiers, accessories and manual revision before disassembly.
- For servers/workstations, match the exact riser, backplane/controller, drive carrier, PSU and rail kit; a matching 2U/4U height alone does not ensure compatibility.
- Keep original brackets, fasteners, trays, feet and front-panel parts labeled with the chassis. Do not force components into modified or incomplete specimens.
