Arista PWR-2411-AC-BLUE | 2400W AC Power Supply, Rear-to-Front Airflow

Q: What is the difference between BLUE and RED handle Arista power supplies?
A: The handle color indicates airflow direction. BLUE indicates rear-to-front (reverse) airflow where air flows from the fan side to the port side. RED indicates front-to-rear (forward) airflow. It is critical to match the PSU airflow direction with your switch configuration and data center hot/cold aisle design.

Q: Which Arista switches are compatible with the PWR-2411-AC-BLUE?
A: The PWR-2411-AC-BLUE is compatible with Arista 7280R3 and 7280R4 series 2RU data center switches including models like DCS-7280CR3-96 and DCS-7280CR3K-96. These switches require the 2400W PSU for full power redundancy. Always verify compatibility with your specific switch model before ordering.

Q: Is this power supply hot-swappable?
A: Yes, the PWR-2411-AC-BLUE is a hot-swappable power supply. This allows you to replace or add power supplies without shutting down the switch, ensuring continuous operation and minimizing network downtime during maintenance.

Q: How many power supplies do I need for redundancy?
A: Arista 7280R3 and 7280R4 series 2RU switches typically support dual power supplies for full redundancy. For N+1 redundancy, configure two PWR-2411-AC-BLUE units so that if one fails, the other can maintain full switch operation. Check your switch datasheet for specific power requirements.

Q: What cables are included with this power supply?
A: Arista 7280R3 models using the 2400W PSU ship with two C19-C20 power cables (2 meters). If ordering the PSU separately as a spare or replacement, you may need to order power cables separately. The PSU uses an IEC 60320 C20 input connector and requires 200-240V AC circuits.
