Introduction

Cisco Catalyst 3850 Series Switches are the next generation of enterprise class stackable access layer
switches that provide full convergence between wired and wireless networks on a single platform. This
convergence is built on the resilience of new and improved 480-Gbps StackWise-480 and Cisco
StackPower. Wired and wireless security and wireless application visibility and control are natively built
into the switch.

Cisco Catalyst 3850 Series Switches also support full IEEE 802.3 at Power over Ethernet Plus (PoE+),
modular and field replaceable network modules, redundant fans, and power supplies. Cisco Catalyst
3850 Series Switches enhance productivity by enabling applications such as IP telephony, wireless, and
video for a true borderless network experience.
