Cisco Catalyst 4500E 7-Slot Chassis | Enterprise Modular Switch — CON-OSP-ISR4X51X

Create a scalable switching foundation with the Cisco Catalyst 4500E 7-slot chassis. This chassis is intended for enterprise environments that need modular growth, serviceable architecture, and the ability to shape the platform around specific power and line-card requirements. The 7-slot design gives infrastructure teams room to plan for density and segmentation without replacing the entire switch as requirements change. That flexibility matters in campus cores, distribution layers, and other network segments where uptime, expansion, and maintenance access all carry real operational cost. This configuration includes fan support and JTFps without a power supply, which makes it suitable for deployments where power architecture is selected separately to match redundancy, capacity, or standardization goals. For procurement teams, that separation can simplify platform alignment across sites. For architects, it preserves design control. Choose this chassis when the network needs a durable modular base rather than a fixed-port switch. It is a practical fit for organizations that value long service life, controlled expansion, and a chassis model that can adapt to changing infrastructure demands. Ideal For Building a campus core switch with room for future line-card expansion Deploying a modular distribution-layer chassis in an enterprise network Standardizing a chassis-based switching platform across multiple sites Selecting a base chassis where power supplies are specified separately Why This Product 1 Offers modular expansion instead of a fixed-port switch design 2 Includes fan support for chassis-based thermal management 3 Leaves power supply selection open for site-specific requirements 4 Fits enterprise campus and distribution deployments
