Cisco WS-CAC-1000W enterprise networking (router/Catalyst switch/UCS families) Datacentre Switch

The Cisco WS-CAC-1000W is a 1000W AC power supply for the Catalyst 6000/6500 series chassis, providing mains AC power to the switch’s Supervisor Engine, MSFC, and installed line cards. It fits the Catalyst 6000/6500 power-supply bay and can be run singly or in a redundant pair with a second supply for N+1 protection, sized for lighter chassis configurations where the full 2500W/2800W/4000W-class supplies are not required. Genuine AC supplies of this rating are a routine spare for operators running Catalyst 6500 switches on mains power, whether replacing a failed unit, restoring redundancy or bringing an under-powered chassis configuration up to its supported power budget. Specifiers should confirm the exact chassis model and total line-card power draw before ordering, since Catalyst 6000/6500 supplies come in several wattage classes that are not universally interchangeable. Tech-Star (UK-based, shipped worldwide) stocks Cisco power supplies to support ongoing network maintenance projects.
