Description

This is a hot-swappable 1500W AC power supply module for the Arista 7280R3A series of data centre switch routers. It suits spare or replacement use in leaf, spine, DCI and routing deployments where the chassis is configured for front-to-rear airflow.

The module takes a 200-240 VAC input at 50/60 Hz, drawing up to 8.5 A through an IEC 60320 C14 inlet, and is rated at 94% Platinum efficiency. It uses a 1RU, 73.5mm form factor and is colour-coded red to identify front-to-rear airflow. The 7280R3A systems use two hot-swap supplies in a 1+1 redundant configuration, so a unit can be replaced without taking the switch offline.

It is listed as a power supply option for the 7280CR3A-72, 7280CR3AM-72 and 7280CR3AK-72 alongside PWR-1512-AC and PWR-1511-DC. Airflow direction must match the fan modules, so pair the red front-to-rear supply with front-to-rear fans and do not mix airflow directions. The reverse airflow counterpart is PWR-1513-AC-BLUE.

FAQs

Q: Which airflow direction does this power supply use?
A: It is the red front-to-rear airflow version. The rear-to-front version is PWR-1513-AC-BLUE, and the two must not be mixed in the same chassis.

Q: What input power does it require?
A: It needs a 200-240 VAC supply at 50/60 Hz, with a maximum input current of 8.5 A through an IEC 60320 C14 inlet.

Q: Which Arista switches does it work with?
A: It is designed for the Arista 7280R3A series, including the 7280CR3A-72, 7280CR3AM-72 and 7280CR3AK-72. These models also list PWR-1512-AC and PWR-1511-DC as power supply options.

Q: Can it be replaced while the switch is running?
A: Yes. The 7280R3A systems use two hot-swap power supplies in a 1+1 redundant configuration, so one unit can be replaced while the other keeps the switch powered.

Q: Do the fan modules need to match the power supply?
A: Yes. Airflow must be consistent across the chassis, so use the red front-to-rear power supply with front-to-rear fan modules.
