Cisco Catalyst 4500E 7-Slot Chassis 48 Gbps/Slot | Enterprise Chassis — CON-SSSNT-IS4321XV

Create a modular switching foundation for campus and enterprise networks with the Catalyst 4500E 7-slot chassis. This platform is built for environments that need slot-based expansion, predictable serviceability, and the ability to scale switching capacity through the right mix of supervisor and line card options. The 48 Gbps per slot design supports high-throughput architectures where backplane headroom matters and where access, aggregation, or core roles may evolve over time. For infrastructure teams, the value of a chassis like this is control. You choose the power configuration, select the modules that match the network design, and preserve a common operational model across sites. That makes it easier to standardize spares, align procurement with deployment plans, and avoid replacing the entire switch when requirements change. This chassis is a strong fit for organizations that want Cisco modularity without overcommitting to a fixed-port design. It is especially relevant where uptime, serviceability, and long-term expansion are more important than lowest initial cost. In practice, that means a cleaner upgrade path, better lifecycle planning, and a switching platform that can adapt as the network grows. Ideal For Campus core switching in enterprise networks Aggregation layer deployment with modular Cisco line cards Distribution switching for multi-building environments Lifecycle-managed infrastructure where power and modules are selected separately Why This Product 1 Modular chassis design offers more lifecycle flexibility than fixed-port switches 2 48 Gbps per slot supports higher-capacity line card planning 3 No power supply included lets teams match the power design to the site 4 Fan support helps maintain thermal management in dense deployments
