Compatibility & safe handling
- Verify full model, suffix, region and revision using the actual unit nameplate and matching manufacturer manual. Wattage and plug shape alone do not establish compatibility.
- Check AC input range, rail and combined output limits, derating, signaling/pinout, cooling direction, mounting and system qualification before installation.
- PSU modular-side cables are model-specific. Never reuse an unapproved lead; a matching plug can carry a different pinout.
- Server hot-plug is permitted only in qualified host configurations and under the host’s documented redundancy/live-service procedure.
- Never open or internally probe the supply. Retire damaged, wet, burnt, corroded, modified or unidentified units.
