3. Complete Product Overview Paragraph
The Cisco Nexus N9K-C93108TC-FX is a compact 1RU fixed Layer 2/3 leaf switch belonging to the Nexus 9300 FX enhanced platform portfolio, designed as top-of-rack leaf nodes for enterprise virtualization, unified compute-storage fabrics and ACI Application Centric Infrastructure environments. It adopts a hybrid port layout with 48 RJ45 copper downlink ports for server access and six QSFP28 multi-rate uplink ports for spine interconnection, delivering full wire-rate non-blocking forwarding with total switching bandwidth of 1.08 Tbps and forwarding throughput of 810 million 64-byte frames per second.
All copper ports support automatic speed negotiation of 100M, 1G and 10G. Cat6A cabling supports full 10G transmission up to 100 meters, while Cat5E cabling limits port speed to a maximum of 5Gbps. Each QSFP28 uplink port supports flexible breakout configurations: 1×100G, 1×40G, 2×50G, 4×25G or 4×10G via DAC breakout cables to meet multi-speed fabric migration demands. Powered by FX-series Cloud Scale ASIC, this platform provides larger shared dynamic packet buffers, expanded L2/L3 table capacity, native hardware acceleration for EVPN/VXLAN overlay routing and wire-rate MACsec encryption, alongside enhanced streaming telemetry compared to earlier EX generation models.
The chassis integrates dedicated out-of-band RJ45 management, mini-USB RS232 console and single USB Type-A port to support POAP zero-touch provisioning, offline configuration backup and firmware upgrades. Dual hot-swappable power supplies and N+1 redundant fan trays eliminate single points of hardware failure, with bidirectional airflow options (PI port-side intake / PE port-side exhaust) selectable at order time to match various rack thermal layout standards. The switch supports two independent operating modes: modular standalone Cisco NX-OS for traditional routed data centers, or native ACI fabric mode for policy-driven automated multi-tenant cloud infrastructure. Equipped with comprehensive unsampled telemetry and open DevOps automation APIs, the N9K-C93108TC-FX balances dense 10G copper server access and scalable high-speed 100G fabric uplinks within a space-saving single rack unit footprint.
