Cisco Series Network Module C3850-NM-BLANK Blank Network for Cisco 3850 Series Switches C3850-NM-BLANK 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.
