Cisco Catalyst 9400 Series 10 Slot Chassis | Modular Core Switch — CON-L1NOS-APIC11L5

Keep critical network services available with a chassis platform designed for enterprise campus cores and distribution layers. The Cisco Catalyst 9400 Series 10-slot system provides a modular architecture with one supervisor slot and two line-card slots, giving teams a structured path for building resilient switching capacity around changing traffic demands. This platform is built for environments where uptime, operational control, and long service life matter more than low-cost commodity switching. Its modular design supports targeted expansion and replacement strategies, helping teams maintain service continuity while aligning hardware investment to network growth. That makes it a strong fit for organizations standardizing on Cisco infrastructure and looking for a chassis that can serve as a stable switching core. For procurement teams, the value is in the chassis model itself: fewer replacement cycles, cleaner lifecycle planning, and a platform intended for enterprise deployment rather than edge-only use. For architects, it offers a foundation that can be shaped around campus segmentation, aggregation, and high-availability design goals without forcing a full refresh when requirements change. Ideal For Campus core switching in enterprise headquarters Distribution-layer aggregation for multi-building networks High-availability switching in standardized Cisco environments Lifecycle-managed chassis refresh for large campus networks Why This Product 1 Modular chassis design versus fixed-port access switches 2 Built for campus core and distribution roles 3 1 supervisor slot and 2 line-card slots for structured expansion 4 Cisco enterprise platform for long-term lifecycle planning
