FAQs

Q: What DC input does this PSU require?
A: A –48 V DC feed (typical telco plant), within the supported operating range specified for the chassis.

Q: Can I mix AC and DC power supplies in the same chassis?
A: Mixing AC and DC PSUs is not supported on most platforms. Use matching input types per your hardware guide.

Q: Is the unit hot-swappable?
A: Yes, it can be replaced without powering down when the chassis supports redundant PSUs.

Q: Does this increase PoE power?
A: It contributes to the overall system power available for PoE; the final PoE budget depends on the switch model and system overhead.

Q: Do I need airflow-matched pairs?
A: Yes. Use identical airflow directions across installed PSUs to maintain proper cooling.
