Q: Does this PSU support hot swapping?
A: Yes. It is a hot-swappable field-replaceable unit for EX4300 Series switches.

Q: Which airflow do I need?
A: Match the PSU airflow to the switch’s existing airflow. AFO is front-to-back; AF is back-to-front. Mixing airflow directions in the same chassis is not recommended.

Q: Is a power cord included?
A: No. The AC power cord is sold separately.

Q: Can I mix different PSU wattages in one switch?
A: It’s best practice to use matching wattage PSUs for predictable power budgeting and redundancy.

Q: Does this increase PoE power?
A: Yes, on PoE-capable EX4300 models the PSU capacity contributes to the overall PoE budget. Actual budget depends on the specific switch model and PSU configuration.

Q: Can I mix AC and DC PSUs in the same chassis?
A: No. Do not mix AC and DC PSU types within the same switch.
