FAQs

Q: How do I choose airflow direction?
A: Match the PSU airflow to your chassis fan module airflow and your rack’s thermal design. Reverse airflow draws air in at the port side.

Q: Can I replace this PSU without powering down?
A: Yes, if your chassis has a second operational PSU. This module is hot-swappable.

Q: Is this interchangeable with the forward-airflow PSU?
A: Functionally similar but airflow must match the chassis airflow. Do not mix airflow types.

Q: What input power does it require?
A: 100–240 VAC, 50/60 Hz.
