WS-C3850-48P-L Use Case
Unified Campus Access for VoIP and Data Convergence with WS-C3850-48P-L
In a 1,500-seat enterprise campus, network engineers deploy the Cisco Catalyst 3850 48 Port PoE LAN Base (WS-C3850-48P-L) as the primary access layer switch to power IP phones, thin clients, and desktop PCs over a single Ethernet fabric. Leveraging integrated PoE+ and industry-leading QoS on IOS-XE, the solution enforces voice-priority traffic and delivers consistent 99.999% uptime via stackable resiliency. Outcome: simplified network operations, guaranteed voice quality, and a 30% reduction in cabling and power infrastructure costs.
High-Density Wi-Fi Aggregation for Campus and Hospitality Environments
A large university deploys up to 48 PoE wireless access points per floor, powered and aggregated through the WS-C3850-48P-L Cisco Catalyst 3850 switch. Using Cisco’s LAN Base feature set and Unified Access Data Plane (UADP) ASIC, network administrators centralize SSID provisioning, apply RF-aware load balancing, and ensure seamless roaming across buildings. Outcome: scalable high-performance Wi-Fi for 10,000 daily users, streamlined roll-out in under two weeks, and a 40% improvement in client throughput.
Secure PoE Edge for Video Surveillance and IoT in Smart Buildings
In a smart office tower, security and facilities teams install 48 IP cameras, environmental sensors, and door controllers powered by a single WS-C3850-48P-L switch per floor. With Cisco TrustSec microsegmentation and 740W PoE budget, each network segment is isolated, and critical data streams receive latency-sensitive treatment. Outcome: end-to-end encryption for all edge devices, 50% faster deployment of security assets, and future-proof capacity for additional IoT integrations.
