Cisco C9300-24T-A Access Enterprise Switch
The Cisco Catalyst 9300-24T-A is a 1 RU fixed-access enterprise switch tailored for U.S. campus and branch deployments—from Silicon Valley innovation centers to Wall Street trading floors.
Part of the Catalyst 9000 family, it features 24 auto-sensing 10/100/1000 RJ-45 data-only downlinks plus one hot-swappable network-module slot (supporting C9300-NM-4G, -8X, -2Q, etc.), powered by a multi-core x86 CPU and Cisco UADP ASIC.
With 208 Gbps of non-blocking switching capacity and Cisco IOS XE with the Network Advantage license, it delivers wire-speed forwarding, deep programmability, and enterprise-grade security—all manageable via Cisco Catalyst Center or Meraki Dashboard.
