The Cisco Catalyst 3850-48XS-S is an enterprise-class stackable Ethernet and Multigigabit Ethernet access and aggregation layer switch that provides full convergence between wired and wireless on a single platform. Cisco's 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 added and improved Cisco StackWise-480 technology. The Cisco Catalyst 3850-48XS-S switch supports full IEEE 802.3 at 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, and redundant fans and power supplies. With its high speed, the Cisco Catalyst 3850-48XS-S Multigigabit Ethernet switch supports optimum wireless speeds and standards on existing cabling infrastructure.
