The Cisco Catalyst 4500 Series offers nonblocking Layer2/3/4 switching with integrated resiliency, further enhancing control of converged networks. Converged voice/video/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 integrated inline power for IP telephony, software-based fault tolerance, and 1 + 1 power supply redundancy. Integrated resiliency in both hardware and software minimizes network downtime, ensuring workforce productivity, profitability, and customer success. As a key component of Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Cisco Catalyst 4500 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 Family line cards and supervisor engines, the Cisco Catalyst 4500 Series enables an extended window of deployment for the Cisco Catalyst 4000 Family in converged networks. This reduces the cost of ownership by minimizing recurring operational expenses, thus improving return on investment (ROI).

The Catalyst 4503-E with CenterFlex technology provides scalable nonblocking Layer 2-4 switching with Secure, Flexible, Non-Stop communications, enabling business resilience for enterprises, small and medium-sized businesses (SMBs), and Metro Ethernet customers deploying business-critical applications. CenterFlex technology is the technology enabled by the Supervisor 6-E centralized ASICs, which deliver the highest centralized performance and configuration flexibility in the industry.The Cisco® Catalyst® 4500 Series Switches enable borderless networks, providing high performance, mobile, and secure user experience through Layer 2-4 switching investments. They enable security, mobility, application performance, video, and energy savings over an infrastructure that supports resiliency, virtualization, and automation. Cisco Catalyst 4500 Series Switches provide borderless performance, scalability, and services with reduced total cost of ownership and superior investment protection.
