Arista PWR-561-AC-RED | 550W AC Power Supply, 1RU, Front-to-Rear Airflow

Q: Which Arista switches is the PWR-561-AC-RED compatible with?
A: The PWR-561-AC-RED is designed for Arista 1RU data center switches including 7050 and 7280 series models. Always verify compatibility with your specific switch model in the hardware documentation.

Q: What does the red handle indicate?
A: The red handle indicates front-to-rear airflow direction, meaning air flows from the switch port side toward the fan tray side. This is critical for proper thermal management in hot-aisle/cold-aisle data center configurations.

Q: Can I mix different power supply models in the same switch?
A: For redundancy configurations, it's recommended to use identical power supply models with matching airflow directions. Mixing different models may impact redundancy capabilities and thermal performance.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-561-AC-RED supports hot-swap functionality, allowing replacement without powering down the switch when operating in a redundant dual-PSU configuration.

Q: What efficiency rating does this power supply offer?
A: The PWR-561-AC-RED delivers approximately 93% efficiency, meeting 80 Plus Platinum standards to minimize energy consumption and reduce operating costs in data center environments.
