WS-C3850-12X48UW-S Use Case
High-Density Enterprise Campus Wi-Fi 6 Rollout
In a multi-building corporate campus, IT teams deploy the WS-C3850-12X48UW-S to power and aggregate 48 wired endpoints alongside 12 multi-gigabit PoE+ Wi-Fi 6 access points using the included 5 AP licenses. The switch’s 60W UPoE capability eliminates separate power injectors, simplifies rack design, and delivers consistent 2.5 Gbps+ wireless backhaul. Outcome: streamlined infrastructure, 30% higher throughput in peak periods, and centralized Cisco DNA Center management for rapid fault resolution.
Smart Manufacturing IoT and Video Surveillance
A discrete factory integrates automated robotics, environmental sensors, and HD cameras on a single network fabric. The 12 mGig UPoE ports on the Catalyst 3850 supply 60W per port for PTZ cameras and industrial Wi-Fi APs, while 48 Gigabit ports connect PLCs and HMIs. The IP Base license enforces micro-segmentation and QoS to prioritize real-time control traffic. Outcome: 40% reduction in downtime, granular security zones, and sub-5 ms latency for critical control loops.
Unified Branch Office Networking with Embedded AP Licensing
A retail chain standardizes branch deployments using the WS-C3850-12X48UW-S to serve up to 5 Cisco access points directly out of the box. All 48 RJ-45 ports support PoE+ for VoIP phones and digital signage, while 12 multi-gig ports future-proof high-speed printers and local servers. Centralized policy enforcement via Cisco IOS XE ensures PCI-DSS compliance across locations. Outcome: 25% faster branch rollouts, zero onsite PoE conflicts, and consistent security posture under a single pane of glass.
