FAQs

Q: Is this PSU compatible with all 7060X and 7280QR models?
A: It is designed for select models in the 7060X and 7280QR families that require 750W AC, rear-to-front airflow PSUs. Check your switch datasheet for exact PSU model support.

Q: Can I mix front-to-rear and rear-to-front airflow PSUs in the same chassis?
A: No. Airflow direction must match across PSUs and fan trays to maintain proper cooling.

Q: Is it hot-swappable?
A: Yes. The module supports online replacement when used per the switch’s maintenance guidelines.

Q: Does this include a power cord?
A: Power cords are typically sold separately. Choose the correct regional cord and C13/C14 requirements for your rack PDU.

Q: How many PSUs are needed for redundancy?
A: Most supported switches use two PSUs for 1+1 redundancy. Refer to your switch hardware guide.
