Cisco C9500-16X-E Full English Product Description
Product Overview
The Cisco Catalyst C9500-16X-E is a 1RU fixed-form-factor core and aggregation switch preloaded with Network Essentials perpetual license, belonging to Cisco flagship Catalyst 9500 enterprise switching portfolio. Built on UADP 2.0 ASIC, multi-core x86 CPU and Cisco IOS XE operating system, it delivers wire-speed 1/10G SFP/SFP+ fiber connectivity, cost-effective Layer 2 & basic Layer 3 forwarding, foundational hardware security and StackWise-480 stacking. It is optimized for medium campus aggregation, small data center leaf-spine fabric and inter-building 10G backbone deployments for networks without advanced routing and zero-trust segmentation demands.
