Arista PWR-1011-DC-RED | 1000W DC Power Supply, Front-to-Rear Airflow, 1RU

Q: Which Arista switches are compatible with the PWR-1011-DC-RED?
A: This power supply is compatible with the Arista 7280CR3-32P4 and 7050X4 series data center switches. Always verify compatibility with your specific switch model before ordering, as power requirements vary across the 7280R3 product line.

Q: What does the red handle indicate on this power supply?
A: The red handle indicates front-to-rear (forward) airflow direction, meaning air flows from the switch port side to the fan side. This is designed for deployments where the rear panel faces the hot aisle.

Q: Can this power supply be hot-swapped?
A: Yes, the PWR-1011-DC-RED is fully hot-swappable, allowing replacement without shutting down the switch. Ensure the power supply is disconnected from the DC power source before removal and that at least one power supply remains connected during the swap.

Q: What wiring is required for DC power installation?
A: Stranded copper wiring up to AWG #6 is supported. The power supply uses twin #10 studs spaced for dual-hole lug with 5/8 inch hole spacing. Wires and lugs must meet local and national electrical installation codes.

Q: Does this support redundant power configurations?
A: Yes, Arista 7280R3 series switches support 1+1 redundant power supply configurations. Installing two power supplies connected to separate DC circuits provides full redundancy protection against power supply failure.
