Power Supplies

This page holds power supplies for Juniper, Cisco, Arista and Foundry switches and routers. The number in a Juniper JPSU part number is its rating in watts, so the JPSU-650W-AC-AFO is 650 W and the JPSU-1600W-AC-AFO is 1600 W. The Cisco C6800-XL-3KW-AC gives 3000 W at 200 to 240 VAC, and the color in an Arista part number such as PWR-511-AC-BLUE names the airflow.
