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

Q: What switches is the PWR-511-DC-BLUE compatible with?
A: The PWR-511-DC-BLUE is compatible with Arista 7050X3 series, 7050X4 series, 7280 series, and 7060CX series 1RU switches. It is designed for deployments requiring DC power and rear-to-front (reverse) airflow cooling.

Q: What does the blue handle indicate?
A: The blue handle indicates rear-to-front (reverse) airflow. This cooling direction is important for proper data center hot aisle/cold aisle configurations. Red handles indicate front-to-rear airflow.

Q: What is the difference between PWR-511-AC and PWR-511-DC models?
A: The PWR-511-AC models accept 100-240V AC input with 93% efficiency, while the PWR-511-DC models accept -48 to -60 VDC input with 92% efficiency. Both provide 500W output and are available in red or blue handles for different airflow directions.

Q: Can I mix AC and DC power supplies in the same switch?
A: While Arista switches support dual power supplies for redundancy, it is recommended to use matching power supply types (both AC or both DC) in the same chassis for consistency and optimal performance.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-511-DC-BLUE is hot-swappable, allowing you to replace or add power supplies without shutting down the switch. This ensures continuous operation and zero downtime during maintenance.
