Enjoy Big Capabilities in a Small Form Factor The Cisco ASR 9006 Router in a 10-rack unit (RU) form factor allows for a full featured, highly reliable deployment in space-constrained environments. This product comes fully equipped with all the same software functionality and line card options as the ASR 9010, just in a smaller package. With dual route switch processors (RSP) along with full commons redundancy, system and network resiliency become a reality for slot-reduced deployments. The ASR 9006 uses an inventive side to back airflow to allow for CO deployment regardless of the horizontal slot orientation. Like the ASR 9010, the ASR 9006 uses the innovative Cisco IOS XR software which is built especially for distributed systems like the Cisco ASR 9000 Series. Cisco IOS XR Software is based on a unique microkernel architecture to enable true modularity. This modularity provides the path to nonstop operations in software image upgrades or module changes without affecting normal platform operations.
