C9400-LC-48U-B Use Case
High-Performance Campus Core Backbone with C9400-LC-48U-B
In a multinational enterprise campus network, IT architects deploy the C9400-LC-48U-B (Catalyst 9400 Series 2×C9400-LC-48U for Bundle Select) as the distribution layer to deliver line-rate 10 GbE to 48 aggregated access switches and 40 GbE uplinks to the core. This configuration ensures sub-50 μs latency, 1:1 oversubscription, and seamless policy enforcement with Cisco DNA Center. Outcome: scalable bandwidth growth, 99.999% availability, and simplified operations through in-service upgrades and unified management.
Leaf-Spine Data Center Switch Fabric Using Catalyst 9400 48U Line Cards
A cloud service provider implements a leaf-spine topology using Catalyst 9400 Series chassis populated with two C9400-LC-48U-B line cards to connect virtualized compute racks. Each 48-port 10 GbE leaf provides high-density east-west traffic aggregation, while 40 GbE spine uplinks eliminate bottlenecks. Outcome: deterministic performance for VM migration, sub-millisecond failover, automated fabric provisioning via Cisco ACI, and a 30% reduction in capex through converged switching and routing capabilities.
High-Density UPOE Edge for Smart Buildings and IoT Applications
A large university campus upgrades its branch distribution closets with C9400-LC-48U-B to power 48 IP cameras, wireless access points, and IoT sensors over UPOE. Integrated PoE management allocates up to 60 W per port, replacing external midspans and cutting cabling complexity. Outcome: centralized energy monitoring, zero-touch device onboarding via Cisco Plug-and-Play, enhanced security segmentation with TrustSec, and 25% lower operational costs through streamlined PoE power budgeting.
