The WS-C3850-24S-E Catalyst 3850 Series is the next generation of enterprise-class stackable Ethernet access and aggregation layer switch that provide full convergence between wired and wireless on a single platform. Unified Access Data Plane application-specific integrated circuit (ASIC) powers the switch and enables uniform wired-wireless policy enforcement, application visibility, flexibility, and application optimization. This convergence is built on the resilience of the improved StackWise-480 technology. The Catalyst 3850 Series Switches support full IEEE 802.3 at Power over Ethernet plus, Universal power over Ethernet, modular and field-replaceable network modules, RJ45, and fiber-based downlink interfaces, and redundant fans and power supplies.
