Cisco Nexus N9K-C9372PX, 1RU rack-mount high-density leaf data center switch, 72 universal multi-rate SFP+ 1/10G fiber ports, 1.44 Tbps non-blocking switching capacity, dual hot-swappable redundant power supplies and variable-speed fan trays, dual-mode standalone NX-OS or ACI fabric operation, optimized for top-of-rack server/storage aggregation, virtualized enterprise and mid-scale ACI data center fabrics.
3. Complete Product Overview Paragraph
The Cisco Nexus N9K-C9372PX is a compact 1RU fixed-port Layer 2/3 Ethernet switch within the original Nexus 9300 classic portfolio, widely deployed as top-of-rack leaf nodes for traditional 10G fiber server and storage racks in enterprise virtualized data centers and ACI intent-based fabrics. Equipped with 72 hot-pluggable universal SFP+ slots supporting auto-negotiated 1G and 10G optical transmission, the chassis delivers full wire-rate non-blocking forwarding with a total switching bandwidth of 1.44 Tbps and a forwarding throughput of 1.08 Bpps for standard 64-byte minimum frames. All SFP+ ports accept industry-standard SFP 1G and SFP+ 10G transceivers, including short-reach SR, long-reach LR, extended-reach ER optical modules and direct attach copper DAC cables for rack internal short-distance connections.
The chassis integrates dedicated out-of-band RJ45 management, mini-USB RS232 console and dual USB Type-A ports to support POAP zero-touch provisioning, offline configuration backup and firmware upgrades. Dual hot-swappable redundant power supply modules and N+1 variable-speed fan trays eliminate single points of hardware failure, with bidirectional airflow options (port-side intake / port-side exhaust) available at ordering to match various rack thermal layouts. This switch supports two independent operating modes: modular standalone Cisco NX-OS for conventional routed data center architectures, or native ACI fabric mode for policy-driven automated multi-tenant infrastructure. Built-in hardware acceleration enables VXLAN EVPN overlay routing, FCoE storage convergence and baseline MACsec encryption, paired with comprehensive telemetry and automation tooling for scalable leaf-spine fabrics. With industry-leading 72-port 10G fiber density in a single 1RU unit, the N9K-C9372PX minimizes rack space consumption for high-volume 10G server and storage aggregation workloads.
