Cisco PWR-4000-DC DC Power Supply

The Cisco PWR-4000-DC is a 4000 W DC power supply module designed for Cisco 7600 Series routers and Catalyst 6500 Series switches, delivering up to 4 kW of DC power to supervisor engines, line cards, and switching fabrics. This modular chassis power supply installs in a power supply slot within supported Cisco 7609, 7609-S, 7613, and Catalyst 6509/6513 chassis, and supports redundant configurations when paired with multiple power supplies. It uses a DC input and includes integrated chassis cooling support, making it ideal for carrier-grade networks. Applications span enterprise core networks, data centers, and service provider infrastructures that require reliable, high-capacity power delivery to large-scale routing and switching deployments.
