FAQs

Q: How do I choose between Intake and Exhaust airflow?
A: Match the PSU airflow to your switch fan airflow and rack thermal policy. Intake is back-to-front; Exhaust is front-to-back.

Q: Is mixing airflow directions supported?
A: No. Use the same airflow direction across all PSUs and fans in the chassis.

Q: Is the PSU hot-swappable?
A: Yes. It can be replaced without powering down when the system has redundant power.

Q: Can I use this with AC-input switches?
A: No. Use only on models that support DC-input PSUs and the 440W rating.

Q: Are DC cables included?
A: No. DC feed wiring and lugs are not included. Use properly rated conductors.

Q: What is the nominal DC feed?
A: –48 VDC or –60 VDC within a supported range of 40–72 VDC.
