FAQs

Q: Is this PSU suitable for DC plant environments?
A: Yes. It is a -48V DC module intended for telco and data center DC power systems.

Q: What does port-side exhaust (PSE) airflow mean?
A: PSE draws air in from the rear and exhausts it out the port (front) side. Match airflow to your rack cooling strategy.

Q: Can I mix PSE and PSI airflow PSUs?
A: No. Use matching airflow PSUs within the same chassis to ensure consistent cooling.

Q: Is it hot-swappable?
A: Yes. With redundant power, you can replace the PSU without taking the switch offline.

Q: Does it work with all Nexus 3550 H models?
A: It is designed for N35-H series switches that accept DC power supplies. Verify your chassis power input type before ordering.
