N9K-C93180YC-FX

The Cisco Nexus N9K-C93180YC-FX is a fixed 1RU Nexus 9300-FX data-center switch designed for top-of-rack, aggregation, storage, and cloud fabric deployments that need high-density 25G server access with 100G uplinks. It provides 48 fiber downlink ports that support 1, 10, and 25 Gigabit Ethernet, plus unified-port support for 16 and 32G Fibre Channel in qualified designs. Six QSFP28 uplink ports support 40 and 100 Gigabit Ethernet, giving teams a clean path from 10G and 40G environments toward 25G leaf and 100G spine architectures. Built on Cisco Cloud Scale ASIC technology, the platform supports NX-OS standalone operation or ACI fabric mode, wire-rate MACsec on supported high-speed ports, and less-than-1-microsecond latency for demanding data-center traffic.

For operators building resilient fabrics, N9K-C93180YC-FX delivers 3.6 Tbps of bandwidth and 1.2 Bpps forwarding performance while maintaining a compact 1RU footprint. This balance helps network teams collapse server access, high-speed appliance connectivity, storage Ethernet, and fabric uplinks into fewer rack units while retaining the operational model many Cisco data-center teams already know. The switch includes up to 32 GB of system memory, a 128 GB SSD, a 40 MB shared system buffer, and scalability for large Layer 2 and Layer 3 environments, including up to 512,000 MAC address entries in the Cisco hardware specification. Hot-swappable power supplies and four fan trays support front-to-back or back-to-front airflow options, and organizations can choose 500W AC, 930W DC, or 1200W HVAC/HVDC power supply options depending on facility power standards. Support for vPC, ECMP, VXLAN EVPN, telemetry, automation APIs, and programmable NX-OS workflows makes the switch useful in highly virtualized data centers where predictable operations matter.

The SKU is especially appropriate when a procurement team needs a proven Cisco Nexus leaf switch for server, storage, or converged LAN and SAN designs rather than a campus access switch. The SFP28 downlinks can connect 10G servers today and support 25G migration later, while the QSFP28 uplinks provide high-speed connectivity to spine switches, aggregation layers, or data-center cores. Because the base model is non-PoE and fiber-focused, it fits rack environments where compute, storage, firewalls, load balancers, and appliances already have local power and short-reach optics or DAC cables are planned separately. The model is currently listed by Cisco as end-of-sale but supported through July 31, 2029, so it remains relevant for expansion, sparing, refurbished sourcing, and like-for-like replacements in existing Nexus 9300-FX fabrics. That makes sourcing consistency and spare planning easier for networks already standardized on this generation. For ORM Systems customers, N9K-C93180YC-FX offers dense 25G access, fixed 100G uplinks, MACsec capability, ACI/NX-OS flexibility, and data-center-class performance in a familiar Cisco Nexus platform.
