FAQs

Q: What does Forward airflow mean?
A: Forward airflow equals Port-side Exhaust: air moves from the port side to the power side (front-to-back).

Q: Can I mix Forward and Reversed airflow PSUs?
A: No. Airflow direction should be consistent across all PSUs and fans in the chassis.

Q: Is this PSU hot-swappable?
A: Yes, in supported Nexus 3000 models with redundant power.

Q: Can I mix AC and DC PSUs?
A: No. Use only the same PSU type supported by your switch.

Q: Are DC cables included?
A: No. Provide appropriately rated DC wiring according to the installation guide.

Q: What DC feed is recommended?
A: –48 VDC nominal within the supported 40–72 VDC range.
