C9400-LC-48U-B1 Use Case
High-Density PoE for Smart Building IoT Deployments
In a large corporate campus rolling out smart lighting, environmental sensors and IP cameras, the C9400-LC-48U-B1 (Cisco Catalyst 9400 Series) delivers 48× 90W PoE+ ports in a modular chassis. By consolidating power and data on a single switch, network architects achieve simplified cabling, zero downtime firmware upgrades and seamless integration with Cisco DNA Center. The outcome: accelerated IoT rollout, 30% lower operational complexity and future-proof scalability for next-gen smart building services.
Secure Multi-Tenant Campus Network Segmentation
University IT teams require granular isolation between administrative offices, research labs and public Wi-Fi. Deploying the C9400-LC-48U with Cisco TrustSec and MACsec on every edge uplink enforces per-user encryption and dynamic VLAN assignment. This solution ensures policy-driven access control, real-time threat containment and 99.99% uptime SLAs. Benefit: airtight campus segmentation, automated compliance reporting and simplified policy orchestration under a single pane of glass.
Scalable Aggregation in Enterprise WAN Edge
Global retailers with dozens of branch offices need high-performance aggregation for POS terminals, VoIP and video analytics. The C9400-LC-48U in Bundle Select acts as a redundant WAN edge switch, supporting up to 1.2Tbps switching capacity and hot-swappable power/line cards. IT managers gain latent-free Layer 2/3 forwarding and zero-impact software patching. Result: predictable network performance, 40% reduced site-to-site latency and continuous business continuity across all locations.
