Q: What distinguishes the –R DC model?
A: It provides front-to-back airflow for environments where intake is at the front and exhaust at the rear.

Q: Is it compatible with AC power bays?
A: It fits the same Config 3 bay form factor but requires a DC input feed; do not mix AC and DC PSUs in most platforms.

Q: Can I replace it while the switch is running?
A: Yes, it is hot-swappable when a second PSU is present or the platform supports live replacement.

Q: How much PoE does it add?
A: Up to its rated capacity contributes to the system; consult your switch documentation for exact PoE budgeting.

Q: Do I need to match airflow with other modules?
A: Yes. Keep airflow direction consistent across all installed PSUs.
