Q: Which switches is this PSU compatible with?
A: It is intended for Nexus 3550 H (N35-H series) switches that accept DC power supplies.

Q: What is port-side intake (PSI) airflow?
A: PSI draws cool air from the front (ports) and exhausts to the rear, aligning with front-to-back cooling designs.

Q: Can I run one DC PSU and one AC PSU together?
A: No. You should not mix AC and DC PSUs within the same chassis.

Q: Is the PSU hot-swappable?
A: Yes. It can be replaced live when the chassis has redundant power.

Q: Do I need to match airflow with the other PSU?
A: Yes. Use the same airflow direction (PSI or PSE) for both PSUs to maintain proper cooling.
