WS-C3850-48U-S Overview
Cisco WS-C3850-48U-S supports Stackable 48 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.
