Description

WS-C3850-24U-E Overview


Cisco WS-C3850-24U-E supports Stackable 24 10/100/1000 Cisco UPOE ports, 1 network 

module slot, 1100 W power supply and 1RU chassis. Cisco Catalyst 3850 Series provides 

capabilities that ideally suited to support the convergence of wired and wireless access. 

The new Cisco Unified Access Data™ Plane (UADP) Application-Specific Integrated 

Circuit (ASIC) powers the switch and enables uniform wired-wireless policy enforcement, 

application visibility, flexibility, and application optimization. This convergence is built on 

the resilience of the new and improved Cisco StackWise®-480 technology.
