FAQs

Q: Which Arista switches is the PWR-500AC-R compatible with?
A: It is a spare 500W AC power supply for Arista 7050X, 7280 and 7060CX 1RU switches, including models such as the 7060SX2-48YC6, 7060CX-32S and 7060CX2-32S.

Q: What does the -R suffix mean?
A: The -R denotes rear-to-front airflow, where air enters at the rear of the switch and exits at the front. It must match the airflow direction of the fans and your rack aisle layout.

Q: What input voltage does this power supply accept?
A: It accepts 100-240 VAC at 50/60 Hz through an IEC 320-C13 input connector, so it works on standard mains power in Australia and internationally.

Q: How efficient is the PWR-500AC-R?
A: It has a typical efficiency of 93% and is Platinum rated.

Q: Can I mix power supplies with different airflow directions in one switch?
A: No. All power supplies and fans in a chassis should use the same airflow direction. Use rear-to-front PSUs only with rear-to-front fan modules.

Q: What is the operating temperature range?
A: The power supply operates from 0 to 40 C (32 to 104 F) at up to 3,000 m altitude and 5 to 95% relative humidity.
