The Cisco Catalyst 3650-48PD-S Network Switch is a next-generation, enterprise-class access-layer switch that provides the foundation for full convergence between wired and wireless on a single platform. Standalone or stackable, this switch is built on the advanced Cisco StackWise-160 and takes advantage of the new Cisco Unified Access Data Plane (UADP) application-specific integrated circuit (ASIC).
