Arista PWR-501AC-F | 500W AC Power Supply, Front-to-Rear Airflow, Hot-Swappable

Q: Which Arista switches is the PWR-501AC-F compatible with?
A: The PWR-501AC-F is specifically designed for the Arista 7050CX3-32S-D switch. It is the 500v2 version with front-to-rear airflow and is not interchangeable with other 7050X or 7280 series power supplies that use the PWR-500AC-F model.

Q: What does the 'F' designation mean in the PWR-501AC-F model number?
A: The 'F' suffix indicates front-to-rear (forward) airflow. This means air is drawn in from the front (port side) of the switch and exhausted out the rear, which is critical for matching your data center's hot aisle/cold aisle cooling design.

Q: Can I mix PWR-501AC-F with the rear-to-front airflow model?
A: No. Mixing airflow directions (PWR-501AC-F and PWR-501AC-R) in the same chassis will cause cooling conflicts and is not supported by Arista. Always use power supplies with matching airflow direction in a redundant configuration.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-501AC-F is hot-swappable and supports 1+1 redundancy. You can replace a failed unit without powering down the switch, ensuring continuous network uptime.

Q: Does the PWR-501AC-F support both 110V and 240V AC input?
A: Yes, the power supply features auto-ranging 100-240V AC input, making it suitable for deployment in data centers worldwide without voltage configuration.
