Arista PWR-511-AC-RED | 500W AC Power Supply, 1RU, Front-to-Rear Airflow

Q: Which Arista switches are compatible with the PWR-511-AC-RED?
A: This power supply is compatible with Arista 7050X3, 7280, and 7060CX series 1RU switches. It is designed for models requiring 500W AC power with front-to-rear airflow configurations.

Q: What does RED mean in the model number?
A: RED indicates front-to-rear airflow direction. Arista uses color-coded designations: RED for front-to-rear (forward) airflow and BLUE for rear-to-front (reverse) airflow to ensure proper cooling direction matching in data center hot/cold aisle deployments.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-511-AC-RED is a hot-plug redundant power supply, allowing replacement or installation without shutting down the connected switch, ensuring continuous network operation.

Q: What is the efficiency rating of this power supply?
A: This power supply features 93% typical efficiency with 80 PLUS Platinum certification, minimizing energy consumption and reducing operational costs in data center deployments.

Q: Can I mix RED and BLUE airflow power supplies in the same switch?
A: No, airflow direction must be consistent throughout the switch chassis. All power supplies and fan modules should match the same airflow direction (either all RED or all BLUE) to maintain proper cooling and prevent thermal issues.
