The Cisco ASR 9000 Series Aggregation Services Router system provides unsurpassed 10GE and 100GE scale and density. The Cisco ASR 9006 and 9010 routers provide an in-place upgrade roadmap to higher density of 10GE and 100GE ports without the need for a complete chassis replacement. These line cards, offered in base and extended-scale configurations, are complemented by the nonblocking fabric (on the Route Switch Processor [RSP] for the Cisco 9006 and 9010 routers and on separate fabric cards for the Cisco 9922 router), and by the innovative backplane (BP), thermal, and power infrastructure on the chassis.
