DataSheet

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 1 + 1 supervisor engine redundancy, 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 Cisco Catalyst 4500 Series, with three supervisor engine options, provides a common architecture that scales to 240 ports of 10/100, 100BASE-FX Fast Ethernet, 1000BASE-LX, or 10/100/1000BASE-T Gigabit Ethernet. The Cisco Catalyst 4507R is the only Cisco Catalyst 4500 Series switch to support 1 + 1 redundant supervisor engines with sub-minute failover time.

Using the same line cards and supervisor engines (Supervisor Engines II and III) as the widely deployed Cisco Catalyst 4000 Series, the Cisco Catalyst 4500 Series enhances the Cisco commitment to affordable enterprise and branch scalability, providing a cost-effective, flexible network solution that scales to meet today's high-performance needs with investment protection.
