Cisco Catalyst 3650 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 160-Gbps StackWise-160. Wired and 
wireless security and wireless application visibility and control are natively built into the switch.

Cisco Catalyst 3650 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. The Cisco Catalyst 
3650 Series Switches enhance productivity by enabling applications such as IP telephony, wireless, and 
video for a true borderless network experience.

Cisco IOS XE Denali 16.x.x and Cisco IOS XE represent the continuing evolution of the preeminent 
Cisco IOS operating system. The Cisco IOS XE architecture and well-defined set of APIs extend the 
Cisco IOS software to improve portability across platforms and extensibility outside the Cisco IOS 
environment. The Cisco IOS XE software retains the same look and feel of the Cisco IOS software, while 
providing enhanced future-proofing and improved functionality.
