Cisco Nexus 9300 C93180YC-FX3 DC Switch
The Cisco Nexus 93180YC-FX3 (N9K-C93180YC-FX3) is a 1 RU, fixed-port data-center switch engineered for U.S. hyperscale and enterprise fabrics—from Silicon Valley AI clusters to Wall Street trading backbones.
Based on Cisco Cloud Scale UADP 2.0 ASIC, it delivers 48 × 1/10/25 Gbps SFP28 fiber downlinks and 6 × 40/100 Gbps QSFP28 uplinks in a compact chassis, providing 3.6 Tbps of full-duplex switching bandwidth and 1.2 billion packets per second of wire-speed forwarding.
Designed for either Cisco ACI or NX-OS mode, it offers real-time streaming telemetry, programmable automation, and enterprise-grade security for modern American data centers.
