The Cisco ASR-903 Chassis is the cornerstone of a robust network infrastructure capable of catering to a string of applications ranging from mobile backhaul to residential and business services. With its modular design, users are presented with the flexibility to tailor the router to their network demands, optimizing both capital and operational expenditures. Durability and reliability are also core advantages; the ASR-903 ensures continuous service delivery with options for redundant power supplies and route switch processors, fostering uptime and peace of mind. The shallow form factor of the chassis underscores its fit for environments where space is at a premium, making it an ideal solution for small-to-medium sized aggregation sites and remote points of presence.
Service providers desiring operational efficiency will appreciate the low power consumption and side-to-side airflow design, which aids in reducing energy costs and simplifies cooling infrastructure. Despite the compact size, the ASR-903 does not compromise on capability. It supports a wide variety of interface modules, from high-density Ethernet to legacy T1/E1 interfaces, enabling comprehensive service integration. Overall, the Cisco ASR-903 is engineered to address the escalating demands for scalable and reliable network services, while also ensuring that future growth can be seamlessly accommodated, thus safeguarding your investment in the ever-evolving landscape of network technology.
Cisco ASR-903 is ASR 900 Series Router Chassis. Cisco ASR 900 Series Aggregation Services Routers are full-featured, modular aggregation platforms. They’re designed for the cost-effective delivery of converged mobile, residential, and business services. You get redundancy, a shallow depth, low power consumption, and high service scale in routers packed with useful features and optimized for small aggregation and remote point-of-presence (POP) applications.
