PWR-500AC-F is the Arista 500 W AC power supply with front-to-rear airflow, sold as a spare for Arista 7050X and 7280R 1RU switches. PWR-500AC-R is the rear-to-front version, and PWR-500-DC-F and PWR-500-DC-R are the 500 W DC equivalents.
It takes 100-240 V AC at 50/60 Hz with a typical input current of 6.3 A down to 2.3 A across that range, and delivers 500 W of output. Typical efficiency is 93% at the Platinum level.
In the 7050X3 range the 500 W AC supply is the power supply for the 7050CX3-32S and 7050CX3-32C, where it is paired with the FAN-7000H-F/R fan tray, and the 7050SX3-48YC12 takes the front-to-rear PWR-500-AC-F with its FAN-7000H-F fan. The 7160 series also uses the 500 W AC supply.
Switches that take this supply are in the Arista switch category, such as the DCS-7050SX-64-F and the DCS-7280SR-48C6-F, and other Arista parts are in the Arista parts category.
