WS-C3750X-48P-S Use Case
High-Density VoIP and Wireless Access in Corporate Campus
In a 1,000-employee corporate campus deploying 200+ IP desk phones and 150 wireless access points across three floors, IT architects use the WS-C3750X-48P-S Catalyst 3750X 48 Port PoE IP Base to deliver 370W PoE power, advanced QoS and StackWise Plus high-availability. The result is seamless voice/video quality, simplified switch stacking, centralized management via Cisco IOS IP Base and a 40% reduction in network downtime.
IP Surveillance and Access Control in Retail Chain
A regional retail chain equips 10 stores with 48 PoE-powered HD cameras, door controllers and RFID readers per location. By deploying WS-C3750X-48P-S Catalyst 3750X 48 Port PoE IP Base at each site, security teams gain robust PoE power budgeting, Layer 3 SVI segmentation for secure VLANs and Cisco TrustSec device authentication. This delivers real-time video integrity, PCI-compliant access control and a 30% drop in investigative response time.
Branch Office Network Aggregation with Layer 3 Routing
A multinational corporation consolidates 25 branch offices under a uniform network design. Each branch installs a WS-C3750X-48P-S Catalyst 3750X 48 Port PoE IP Base as the primary aggregation switch, supporting static/dynamic Layer 3 routing, DHCP snooping and 48 PoE endpoints (IP phones, APs). The deployment achieves under-5ms failover, automated port security and a 50% reduction in branch-level IT support tickets.
