Cisco ASR 9000 Series Routers are designed to provide true carrier-class reliability using the Cisco IOS XR operating system, comprehensive system redundancy, and a full complement of network resiliency schemes. The Cisco ASR 9000 Series also offers service and application-level intelligence focused on optimized video delivery and mobile aggregation. Finally, the Cisco ASR 9000 Series is designed to simplify and enhance the operational and deployment aspects of service-delivery networks.The Cisco ASR 9000 Series provides an in-place upgrade roadmap to a switching capacity of up to 400 Gbps per slot without the need for a complete chassis replacement. This game changing ball is set rolling with a set of high density GE and 10GE Ethernet Services line cards utilizing versatile network processors to support an array of Carrier Ethernet applications. These Line-Cards, offered in base and extended-scale configurations, are complemented by the non-blocking fabric on the Route Switch Processor (RSP) and the future ready Back-Plane (BP), thermal and power infrastructure on the chassis.The optimized thermal infrastructure of the Cisco ASR 9000 Series is designed to be scalable to support the future capacity requirements. Variable-speed high-efficiency fans provide reduced power requirements under normal operating environments while retaining capability to cool current and future line cards under extreme conditions.
