The Cisco WS-C6504-E Catalyst 6500-E Series Modular Switch Chassis is a scalable, high-performance networking platform designed for enterprise core, distribution, data center, and service provider environments. Built on Cisco's proven Catalyst 6500-E architecture, this 4-slot chassis delivers exceptional flexibility, high availability, and investment protection for organizations requiring mission-critical network infrastructure.

The chassis features four modular slots, including dedicated supervisor engine slots and line card/service module slots, enabling organizations to customize network deployments based on performance, connectivity, and service requirements. Support for Supervisor 32, Supervisor 720, and Supervisor Engine 2T provides a scalable upgrade path from hundreds of gigabits to multi-terabit switching performance.

With a base switching capacity of up to 320 Gbps and support for enhanced bandwidth through advanced supervisor engines, the WS-C6504-E is designed to handle demanding enterprise applications, campus backbone traffic, data center workloads, and service provider aggregation services. Its modular architecture supports a wide range of interfaces, including Gigabit Ethernet, 10 Gigabit Ethernet, and advanced service modules.

The platform offers enterprise-grade resiliency through redundant supervisor engines, redundant AC/DC power supplies, and hot-swappable fan trays, helping ensure continuous operation and minimizing downtime. High-availability features such as Stateful Switchover (SSO) further enhance network reliability for critical business environments.

The WS-C6504-E supports advanced networking services including Layer 2 and Layer 3 switching, IPv4, IPv6, MPLS, QoS, access control lists (ACLs), firewall services, intrusion prevention, and load-balancing modules. Running Cisco IOS or CatOS, it provides comprehensive management and security capabilities for complex enterprise networks.

Ideal for enterprise core switching, campus distribution layers, data center aggregation, service provider edge deployments, and high-availability network infrastructures, the Cisco WS-C6504-E delivers the performance, scalability, and reliability required for modern mission-critical networking environments.
