Cisco A9K-750W-DC Power Supply

The Cisco A9K-750W-DC Power Supply is a 750 W DC power module for the Cisco ASR 9001 router, part of the Cisco ASR 9000 Series, converting -48 V to -72 V DC input into regulated power for the router chassis and its internal networking components. It supports dual redundant power configurations for high availability, is hot-swappable, and mounts in an internal router power bay with integrated chassis airflow cooling to maintain stable operation in carrier-grade deployments. Widely used in service provider and enterprise networks—including ISP backbone, metro Ethernet, telecommunications switching facilities, data center routing platforms, and large enterprise deployments that require stable DC power for Cisco IOS XR-based ASR 9000 routing platforms.
