Cisco Catalyst 9400 Series 10-Slot Chassis | Modular Campus Switch — CON-L1NOS-C93004UA

Keep critical campus traffic moving with a chassis built for scale, serviceability, and operational continuity. The Cisco Catalyst 9400 Series 10-slot platform is designed for enterprise switching environments that need modular growth without replacing the entire system. With support for one supervisor and two line cards, it gives infrastructure teams a controlled path to expand capacity while preserving the investment already in place. This chassis fits networks where downtime is expensive and change windows are short. Its modular design helps separate control, forwarding, and expansion planning so teams can align hardware refreshes with business demand instead of forcing a forklift upgrade. That makes it a strong fit for core and distribution deployments, large campus aggregation, and environments that need predictable scaling over time. The included DNA Advantage licensing aligns the platform with policy-driven operations and lifecycle management. For organizations standardizing on Cisco campus architecture, this model offers the hardware foundation needed for resilient switching, while leaving room for future module selection based on port density, uplink strategy, and service requirements. It is the kind of platform chosen when the network must stay stable today and remain adaptable tomorrow. Ideal For Campus core switching for large enterprise headquarters Distribution-layer aggregation in multi-building networks Modular refresh projects that require phased expansion Standardized Cisco campus deployments with lifecycle management Why This Product 1 Modular chassis architecture instead of fixed-port switching 2 1 supervisor and 2 line-card slots for planned expansion 3 DNA Advantage licensing for operational control 4 Built for campus core and distribution environments
