Cisco C9500-16X-2Q-E Full English Product Description
Product Overview
The Cisco Catalyst C9500-16X-2Q-E is a 1RU modular high-performance aggregation/core switch preloaded with Network Essentials perpetual license, belonging to Cisco flagship Catalyst 9500 enterprise switching portfolio. Built on UADP 3.0 ASIC, multi-core x86 CPU and Cisco IOS XE operating system, it combines 16×1/10G SFP+ downlink ports with an integrated 2×40G QSFP+ uplink module, balancing high-density 10G access aggregation and high-speed 40G backbone connectivity. Optimized for cost-sensitive enterprise campus aggregation, small-to-medium data center leaf nodes, multi-server rack aggregation and inter-building fiber backbone deployments that only require foundational Layer 2/3 routing and basic security capabilitiesCisco.
