A next generation Cisco Catalyst 4000 Family platform for Intelligent Switching, the Catalyst 4500 series includes three new Catalyst chassis: Catalyst 4507R (7-slot: redundant Supervisor IV capable), Catalyst 4506 (6-slot) and Catalyst 4503 (3-slot). A key component of Cisco AVVID (Architecture for Voice, Video and Integrated Data), the Catalyst 4500 extends control to Enterprise wiring closets, branch office and Layer 3 distribution points. The Catalyst 4500 is also optimized for business services aggregation and subscriber access in the metropolitan area for network operators and service providers.

Cisco Catalyst 4500 Supervisor IV Engine: Delivers integrated resiliency and non-blocking Cisco Express Forwarding (CEF)-based Layer 2/3/4 switching at 48 Mpps, to further enhance control of converged networks. Key intelligent services, based on proven Cisco IOS software, include granular Quality of Service (QoS), predictable performance, advanced security, comprehensive manageability and integrated resiliency. The Supervisor Engine IV is compatible with the new Catalyst 4500 Series chassis, the widely deployed Catalyst 4006 chassis, and existing Catalyst 4000 Family line cards for maximum deployment flexibility.

Cisco Catalyst 4500 Series 48-Port 1000Base-LX Gigabit Ethernet Line Card: Compatible with both the Catalyst 4500 Series and the Catalyst 4000 Series modular chassis these linecards can be mixed and matched to to suit a wide-range of customer wiring closet, branch office, data center and metro Ethernet deployments. Catalyst 4000 Family linecards offer high density copper and fiber based interfaces for both Fast Ethernet and Gigabit Ethernet connectivity.

Cisco Catalyst 4000 Series: As part of the Catalyst 4000 Family platform, the Catalyst 4000 Series includes the Catalyst 4006 (6-slot) and Catalyst 4003 (3-slot) chassis. The Catalyst 4000 Series enhances Cisco's 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.

A variety of network infrastructure solutions are enabled by the Catalyst 4000 Family of switches including: Cisco AVVID Network Infrastructure, IP Telephony, Metro Ethernet Switching, Gigabit Ethernet, Ethernet in the First Mile, and the CWDM GBIC Solution.
