FAQs

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

Q: Should airflow direction match across components?
A: Yes. Match PSU airflow with system fans and the overall rack thermal policy.

Q: Is it hot-swappable?
A: Yes, when installed in a supported chassis with redundant power.

Q: Can I use this with AC-input models?
A: No. Use only with models that support DC-input 500W PSUs.

Q: Are DC harnesses included?
A: No. Field wiring is required; follow the hardware installation guide and local codes.

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