ASR-903 Cisco ASR Router Chassis with Fan
Cisco ASR-903 ASR 903 Router Chassis with Integrated Fan Module
Compact Cisco ASR 903 Chassis for Scalable Edge Routing with Efficient Cooling
NOTE: POWER SUPPLIES ARE NOT INCLUDED AS STANDARD AND CAN BE PURCHASED HERE.
The Cisco ASR-903 Router Chassis is a compact, high-performance platform designed for service provider and enterprise edge networks, delivering scalable and reliable routing for modern infrastructures. As part of the Cisco ASR 900 Series, it is engineered to support edge routing, aggregation, and packet transport applications in demanding environments.
Built with a modular architecture, the ASR-903 allows flexible deployment through support for interface modules, service modules, and redundant Route Switch Processors (RSPs). This enables organizations to customize configurations based on evolving network requirements while ensuring long-term scalability.
The chassis features an integrated fan module with front-to-back airflow, providing efficient thermal management and consistent performance in high-density deployments. Designed for carrier-grade reliability, it supports redundant power supplies and high-availability features such as Nonstop Routing (NSR) and Stateful Switchover (SSO), ensuring minimal downtime in mission-critical networks.
Running on Cisco IOS XE, the ASR-903 supports advanced routing protocols including BGP, OSPF, IS-IS, and MPLS, along with QoS and network synchronization features such as IEEE 1588v2 and SyncE, making it ideal for telecom and metro Ethernet environments.
With its compact 2RU form factor, high performance, and flexible scalability, the Cisco ASR-903 is well-suited for service provider edge networks, enterprise WAN deployments, and telecom infrastructure requiring reliable, high-capacity routing.
Ideal for metro aggregation, ISP edge, and enterprise WAN edge deployments, the Cisco ASR-903 Router Chassis provides a future-ready solution for scalable and high-performance networking.
