The Cisco Catalyst 4500 Series offers nonblocking Layers 2 through 4 switching with integrated resiliency, further enhancing control of converged networks. Converged voice, video, and data networks with high availability enable business resiliency for enterprise and metropolitan (metro) Ethernet customers deploying Internet-based business applications. Integrated resiliency enhancements offered in the Cisco Catalyst 4500 Series include 1+1 supervisor engine redundancy (Cisco Catalyst 4507R/4510R), integrated IEEE 802.3af compliant Power over Ethernet, software-based fault tolerance, and 1+1 power supply redundancy. Integrated resiliency in both hardware and software minimizes network downtime, helping to ensure workforce productivity, profitability, and customer success. An important component of Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Cisco Catalyst 4500 Series extends control to the network edge with intelligent network services, including sophisticated quality of service (QoS), predictable performance, advanced security, comprehensive management, and integrated resiliency. Offering compatibility with Cisco Catalyst 4000 Series line cards and Supervisor Engines, the Cisco Catalyst 4500 Series provides an extended window of deployment for the Cisco Catalyst 4000 Series in converged networks. This reduces the cost of ownership by minimizing recurring operational expenses, improving return on investment (ROI). The Cisco Catalyst 4510R provides increased high availability in supporting 1+1 redundant supervisor engines with sub-minute failover time. Using the same line cards and Supervisor Engines as the widely deployed Cisco Catalyst 4000 Series, the Cisco Catalyst 4500 Series enhances the Cisco commitment to affordable enterprise and branch scalability. It provides a cost-effective, flexible network solution that scales to meet today's high-performance needs with investment protection.
