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

Q: What Arista switches are compatible with the PWR-511-AC-BLUE?
A: The PWR-511-AC-BLUE is compatible with 1RU Arista switches including the 7050X3, 7050X4, 7280R3, and 7060CX series. The blue handle indicates rear-to-front airflow, so ensure your switch chassis airflow matches this configuration.

Q: What does the blue handle indicate?
A: The blue handle indicates rear-to-front (reverse) airflow direction. This means the unit draws air from the rear panel and exhausts it toward the front. Red handles indicate forward airflow (front-to-rear). All power supplies and fan modules in a switch must have matching airflow directions.

Q: Can I hot-swap this power supply?
A: Yes, the PWR-511-AC-BLUE supports hot-plug installation and removal, allowing you to replace or add power supplies without shutting down the connected switch. This is critical for maintaining uptime in redundant power configurations.

Q: What is the difference between PWR-511-AC-BLUE and PWR-511-AC-RED?
A: The only difference is airflow direction. The PWR-511-AC-BLUE has rear-to-front (reverse) airflow with a blue handle, while the PWR-511-AC-RED has front-to-rear (forward) airflow with a red handle. Both provide 500W AC power output. Choose based on your data center hot/cold aisle configuration.

Q: What cable is required to connect this power supply?
A: The PWR-511-AC-BLUE uses a standard IEC 320-C13 AC power connector. A C13-to-C14 power cable is typically included with Arista accessory kits, or can be ordered separately. Ensure your AC circuit provides 100-240V at 50/60Hz.
