Q: What does Port-side Intake (PI) mean?
A: PI airflow draws cool air in from the port side toward the PSU side. Choose PI or PE to match your deployment’s airflow requirements.

Q: Does this unit support both AC and DC feeds?
A: Yes. This HVAC/HVDC model can operate from high‑voltage AC or high‑voltage DC, as supported by the platform and power infrastructure.

Q: Is it hot-swappable?
A: Yes, it can be replaced without interrupting operation when the switch/chassis supports hot-swap power supplies.

Q: Can I mix PI with PE power supplies?
A: Airflow types should match per platform guidance. Do not mix PI and PE in the same chassis unless the vendor documentation explicitly allows it.

Q: How many PSUs do I need?
A: Size to your maximum load and redundancy target. Many deployments use N+1; consult your platform’s power calculator.
