Product Overview
The Catalyst 3850 family of switches are Ethernet switches to which you can connect devices such as Cisco
IP Phones, Cisco Wireless Access Points, workstations, and other network devices such as servers, routers,
and other switches.
The Catalyst 3850 switches support stacking through Cisco StackWise-480 technology and power management
through StackPower. The StackWise technology for the Catalyst 3850 switches is called StackWise-480.
Unless otherwise noted, the term switch refers to a standalone switch and to a switch stack.
