WS-C3750X-48U-L Use Case
Campus LAN Aggregation & PoE+ Delivery for Unified Communications
In a large enterprise wiring closet, the WS-C3750X-48U-L stackable switch aggregates 48 10/100/1000 PoE+ ports to power VoIP phones and wireless access points. By leveraging StackWise™ technology and a 740W PoE+ budget per switch, IT teams achieve sub-millisecond failover and centralized power management, resulting in uninterrupted voice/video collaboration and simplified infrastructure scaling.
High-Density Top-of-Rack for Virtualized Data Center
Deployed at the top of a 42U rack, the WS-C3750X-48U-L delivers 48 Gigabit Ethernet uplinks to hypervisor clusters and SAN gateways. Its non-blocking 176 Gbps switching fabric and hot-swappable SFP uplinks ensure low-latency traffic flow and seamless expansion. Outcome: streamlined VM migration, predictable East-West throughput, and reduced single-point failure risk in virtualized environments.
Secure IoT Edge Hub in Smart Building Environments
In a multi-tenant smart facility, the WS-C3750X-48U-L aggregates IP cameras, environmental sensors and access controllers over 48 PoE+ ports. Advanced QoS, Dynamic ARP Inspection and flexible VLAN segmentation isolate critical building systems. Benefit: centralized power delivery, real-time device monitoring, and hardened network security for scalable IoT deployments.
