The Cisco Catalyst 3850 series is the next generation of enterprise class stackable Ethernet and Multigigabit Ethernet access and aggregation layer switches that provide full convergence between wired and wireless on a single platform. Cisco's Unified Access Data Plane application specific integrated circuit 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 Cisco StackWise 480 technology. The Cisco Catalyst 3850 series Switches support full IEEE 802.3 at Power over Ethernet Plus (PoE+), Cisco Universal Power over Ethernet (Cisco UPOE), modular and field replaceable network modules, RJ45 and fiber based downlink interfaces, and redundant fans and power supplies. With speeds that reach 10Gbps, the Cisco Catalyst 3850 Multigigabit Ethernet Switches support current and next generation wireless speeds and standards on existing cabling infrastructure.
