The Cisco Catalyst 3850 series, the enterprise-class stackable Ethernet and Multigigabit Ethernet access and aggregation layer switches, provide full convergence between wired and wireless on a single platform. Unified Access Data Plane (UADP) 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 Cisco StackWise-480 technology. The Cisco Catalyst 3850 series switches support full IEEE 802.3at Power over Ethernet Plus (PoE+), Cisco Universal Power over Ethernet (Cisco UPOE), modular and field-replaceable network modules, RJ-45 and fiber-based downlink interfaces, redundant fans and power supplies. With the high speeds the Cisco Catalyst 3850 Multigigabit Ethernet Switches support wireless speeds and standards on existing cabling infrastructure.
