Product Overview
The Cisco Nexus N9K-C93180YC-FX3 is a high-performance, ultra-low latency 1RU fixed-configuration switch engineered for next-generation cloud, enterprise data center, and high-frequency trading environments. Operating as a pillar of the Cisco Nexus 9300 family, this architecture provides 48 flexible 1G/10G/25G SFP28 downlink ports paired with 6 high-speed 40G/100G QSFP28 uplink ports.
Built to handle intensive data virtualization, AI telemetry, and spine-leaf storage fabrics, the N9K-C93180YC-FX3 features line-rate MACsec hardware encryption for robust Layer 2 security, alongside Synchronous Ethernet (SyncE) for precise time-frequency synchronization. Whether deployed as a Top-of-Rack (ToR) switch or an enterprise aggregation backbone, this platform delivers unmatched non-blocking throughput and network resilience.
