Cisco Nexus N9K-C93240YC-FX2 Data Center Switch

The Cisco Nexus N9K-C93240YC-FX2 is a high-density data center switch offering 4.8 Tbps bandwidth. Featuring 48x 25G downlinks and 12x 100G uplinks, it delivers wire-rate MACsec, Fibre Channel support, and ACI integration for converged cloud networks.
Quick Specs:
· Downlinks: 48 x 1/10/25G SFP28 (Supports 8/16/32G Fibre Channel)
· Uplinks: 12 x 40/100G QSFP28
· Bandwidth: 4.8 Tbps
· Security: MACsec on all ports
· OS Support: NX-OS & Cisco ACI
· Form Factor: 1RU Top-of-Rack (ToR)

Comprehensive Product Overview

The Cisco Nexus N9K-C93240YC-FX2 is a formidable 1-Rack-Unit (1RU) Top-of-Rack (ToR) and aggregation switch designed for the most demanding enterprise data centers and service provider environments. Powered by the Cisco Cloud Scale ASIC, it provides a massive 4.8 Terabits per second (Tbps) of switching capacity, completely eliminating network bottlenecks in heavily virtualized and storage-intensive racks.

What truly sets the N9K-C93240YC-FX2 apart is its extraordinary uplink density and storage integration. With 12 x 100G QSFP28 uplinks (double that of standard ToR switches) and native support for Fibre Channel (FC) and FCoE, this switch enables true LAN/SAN convergence. It allows enterprises to unify their Ethernet and Storage Area Networks on a single, high-performance Cisco ACI or NX-OS fabric.

Key Features & Business Benefits

Extreme Uplink Capacity: Prevent oversubscription. The 12x 100G QSFP28 uplink ports ensure a non-blocking architecture even when all 48 downlink ports are running at maximum 25G capacity, making it perfect for hyperconverged infrastructure (HCI).
Unified LAN/SAN Convergence: Significantly reduce cabling and hardware costs. The downlink ports can be configured as 8/16/32-Gbps Fibre Channel ports, allowing you to connect Ethernet servers and Fibre Channel storage arrays directly to the same switch.
End-to-End MACsec Security: Protect your intellectual property and comply with strict data regulations. The FX2 ASIC provides hardware-based, wire-rate IEEE 802.1AE MACsec encryption across all 60 ports without sacrificing throughput.
Flexible Operating Modes: Future-proof your investment. Operate in standard NX-OS mode for robust, traditional BGP/EVPN VXLAN routing, or deploy in Cisco ACI mode to enable policy-driven, automated Spine-Leaf architectures.
Deep Visibility & Telemetry: Built-in streaming telemetry, precision time protocol (PTP), and flow table logging offer unprecedented, real-time insights into network performance and traffic microbursts.

Ideal Application Scenarios

Heavy-Traffic ToR Leaf: Perfect for big data clusters, AI/ML computing racks, and NVMe-over-Fabric (NVMe-oF) deployments where 6 uplinks are simply not enough to handle the server-to-spine traffic ratio.
Storage Area Network (SAN) Consolidation: Use the Fibre Channel capabilities to connect legacy SAN arrays and modern Ethernet storage seamlessly within the same 1RU switch, reducing data center footprint.
High-Density Aggregation: Deploy as a middle-of-row (MoR) or aggregation switch for smaller data center pods, utilizing the 12x 100G ports to connect downstream 10G/25G switches.

Supported Accessories & Optics
