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.

Product Overview Fan Module Considerations for the WS-C3850-12X48U-L, WS-C3850-12X48U-S and WS-C3850-12X48U-E switch Note models: • The primary power supply for these switch models should be a minimum of 470 W. • 350 W or 440 W can be used only as secondary power supplies. If the switch draws power from these modules as the primary source, reboot the switch to restore these modules as secondary power supplies. - Page 30 Product Overview Fan Module The following illustrations show the airflow patterns for the 24- and 48-port switches.
