Preservation and installation notes
Match the chassis PID/service tag to the backplane, drive carriers, risers, fan modules, PSU units and rail kit; same-family servers often have incompatible option cages.
- Photograph the complete model label, assembly revision and option identifiers before opening; keep matching covers, brackets, shields, trays and fasteners together.
- Confirm rack depth, rail travel, cable-management clearance and host/HBA support before installation; hot-swap bay count alone does not identify backplane compatibility.
