Q: Is this PSU compatible with Nexus 3550 H switches?
A: Yes. It is designed for Nexus 3550 H (N35-H series) chassis requiring an AC power supply with port-side intake airflow.

Q: What does port-side intake (PSI) airflow mean?
A: PSI draws cool air in from the port (front) side and exhausts it toward the rear. Match airflow to your chassis and data center hot/cold aisle design.

Q: Can I mix AC and DC power supplies in the same chassis?
A: No. Do not mix AC and DC PSUs in the same switch. Use matching PSU types and airflow directions.

Q: Is the module hot-swappable?
A: Yes. It can be replaced without powering down the switch when a redundant PSU is present.

Q: How do I confirm airflow orientation?
A: Check the PSU label and handle color coding. This unit is specifically labeled as port-side intake (PSI).
