FAQs

Q: What is the difference between AFO and AFI airflow?
A: AFO drives air from port side to PSU side (front-to-back), while AFI drives air from PSU side to port side (back-to-front).

Q: Can I mix AFO and AFI components in the same chassis?
A: No. Use a consistent airflow direction (AFO or AFI) across fans and power supplies for proper cooling.

Q: Is the fan module hot-swappable?
A: Yes. It can be replaced while the switch is powered, minimizing service disruption.
