FAQs

Q: How does –R airflow differ from –F?
A: The –R variant uses front-to-back airflow, while –F uses back-to-front. Choose the model that aligns with your rack’s thermal design.

Q: Can I mix –R and –F power supplies?
A: No. Use the same airflow direction across all installed PSUs for consistent cooling.

Q: Is there any performance difference between –R and –F?
A: Electrical performance is the same; only the airflow direction differs.

Q: Will this PSU work without a second supply?
A: Yes. A single supply can power the chassis within its power budget; a second supply provides redundancy or additional PoE capacity depending on platform.

Q: Do I need a special power cord?
A: Use a region-appropriate AC power cord compatible with the chassis inlet rating. Refer to your switch hardware guide.
