Product Overview for the Cisco ASR-903 8 Slots Router Chassis

The Cisco ASR-903 router series is part of Cisco's highly regarded Aggregation Services Router (ASR) family, known for delivering scalable and reliable network services. The ASR-903 model, in particular, stands out due to its 8 Slots Redundant Power Supply, enhancing its resilience and ensuring continuous operation even in the face of power supply challenges. The Cisco ASR-903 is part of the ASR 900 Series, known for its scalability, flexibility, and advanced features. This series is tailored to address the challenges posed by the ever-expanding digital landscape, making it an ideal choice for enterprises, service providers, and data centers.

Key FeaturesHigh Scalability

The 8-slot configuration of the ASR-903 allows for high scalability, making it an ideal solution for networks with varying sizes and requirements. The ability to accommodate a diverse range of modules and interfaces ensures that the router can adapt to changing network dynamics without the need for a complete overhaul.

8-Slot Design for Enhanced Scalability

The 8-slot design of the ASR-903 chassis stands out as a defining feature. This allows for the integration of multiple interface modules, offering scalability to adapt to the evolving requirements of a network. Whether in a small business or a large enterprise setting, the ability to expand the router's capabilities ensures a future-proof networking solution.

Modular Design

Modularity is at the core of the ASR-903's design philosophy. The router chassis supports a modular approach, allowing users to customize and expand functionality as needed. This modular design not only simplifies upgrades but also future-proofs the network infrastructure, enabling organizations to stay ahead in the ever-advancing technological landscape.

Enhanced Reliability

The inclusion of redundant power supplies significantly enhances the reliability of the ASR-903. In mission-critical applications where downtime can lead to substantial financial losses, having a router chassis that can withstand power failures is paramount. The redundant power supply ensures continuous operation, minimizing the risk of service interruptions.

Rack-Mountable Design

The 3U rack-mountable form factor of the ASR-903 adds to its versatility, making it suitable for data centers and networking closets with space constraints. The rack-mountable design not only optimizes space utilization but also facilitates easy integration into existing rack infrastructure. The 3U rack-mountable design of the ASR-903 adds to its versatility. It allows for efficient utilization of rack space, crucial in data centers where space optimization is a top priority. The rack-mountable form factor also simplifies.

Redundant Power Supply

The Redundant Power Supply feature in the ASR-903 is a critical aspect of its reliability. Redundancy ensures that the router remains operational even in the event of a power supply failure. This feature is crucial for businesses that cannot afford downtime and demand a high level of network availability. A standout feature of the ASR-903 is its redundant power supply, which ensures uninterrupted operation even in the face of power failures. Redundancy is crucial in critical networking environments, where downtime is not an option. The dual power supply design not only enhances reliability but also contributes to the overall robustness of the system.

Benefits of Redundant Power Supply
  • Enhanced Reliability: The primary advantage of redundant power supply is enhanced reliability. In critical networking environments, maintaining constant uptime is non-negotiable. The redundant power supply ensures that if one power source fails, the backup power supply seamlessly takes over, minimizing the risk of downtime.
  • Fault Tolerance: The ASR-903's redundant power supply design contributes to fault tolerance. In the event of a power supply unit malfunction, the redundant system acts as a fail-safe, preventing a single point of failure and maintaining continuous network operation.
  • Scalability and Growth: Businesses evolve, and so do their networking needs. The redundancy in power supply allows for easy scalability. As the network expands, additional power supply units can be seamlessly integrated, accommodating the growing demands of the infrastructure.
Use Cases and Applications
  • Enterprise Networks: The ASR-903 is well-suited for large enterprise networks where a high level of reliability and scalability is paramount. Its 8-slot configuration and redundant power supply make it an ideal choice for businesses with diverse networking needs.
  • Service Providers: Service providers, such as ISPs and telecommunications companies, can benefit from the ASR-903's robust design. The ability to scale and maintain continuous operation ensures a seamless user experience for their customers.
  • Data Centers: In data center environments, where space is often at a premium, the rack-mountable design of the ASR-903 becomes a valuable asset. The 3U form factor allows for efficient use of rack space, contributing to overall data center optimization.
