N9K-C9372TX is a fixed-port data center switch with 48 copper 100M/1/10GBASE-T access ports and six built-in 40G QSFP+ uplinks. The default NX-OS software provides Layer 2 switching, security, and management rather than an included enhanced routing entitlement. This N9300 model occupies one rack unit and provides data connectivity without powering attached endpoints over Ethernet. The Cisco Nexus 9000 family supports top-of-rack and middle-of-row layouts, including server access beneath an aggregation layer or within a leaf-and-spine fabric. The discontinued N9K-C9372PX uses SFP+ access connections instead of copper ports. Uplinks are fixed, so selecting this chassis commits the order to its built-in uplink architecture rather than a removable uplink card.
N9K-C9372TX price for new stock is $13,611.15. N9K-C9372TX refurb price is $399.00. N9K-C9372TX is in stock and available for next-day dispatch. (terms applied)

1440 Gbps of switching capacity accommodates traffic across the access and uplink interfaces. More than 1150 Mpps of forwarding performance provides a separate packet-rate reference for sizing workloads with small frames. N9K-C9372TX combines 16 GB of DRAM with a 64 GB SSD for local storage. 96000 MAC address entries set the upper address-table scale, with attainable capacity depending on the forwarding mode. VLAN capacity reaches 4096 for segmentation across server networks. Intelligent API remote procedure calls use JSON or XML for automation, while command-line license checks identify installed entitlements and active feature usage. Four fans provide active cooling within an operating temperature range of 0°C to 40°C. 694W maximum input draw is the rack-circuit sizing reference, not an individual power module's output rating; the power feed must be sized for input consumption rather than typical draw alone.
ORM Systems supplies N9K-C9372TX new sealed or certified refurbished; refurbished units are inspected and bench-tested for optics bay recognition, with firmware verified and configurations wiped to factory default.

In a hyper-scale data center deploying a spine-leaf architecture, network engineers install the N9K-C9372TX-Nexus 9300 (48p 1/10G-T, 6p 40G QSFP+) as leaf switches to aggregate east-west VM traffic. By delivering wire-speed 10G connectivity on 48 copper ports and six 40G uplinks, it accelerates virtualization, reduces latency below 2 µs, and scales non-disruptively to support over 10,000 VMs. The outcome is guaranteed application performance, simplified automation via NX-OS programmability, and a 30% improvement in data-center throughput.
Large enterprises deploying Gigabit and 10 Gigabit desktop and wireless access in multi-building campuses leverage the N9K-C9372TX-Nexus 9300 (48p 1/10G-T, 6p 40G QSFP+) at the aggregation layer. It consolidates 1G/10G PoE switches, supports secure segmentation with VXLAN EVPN, and delivers up to 240 Gbps of switch capacity per uplink blade. Benefits include unified wired/wireless user access, seamless failover with redundant 40G trunks, and a 40% reduction in switch-farm footprint, strengthening campus security and user experience.
For cloud and edge service providers hosting multi-tenant workloads, the N9K-C9372TX-Nexus 9300 (48p 1/10G-T, 6p 40G QSFP+) serves as a high-performance spine switch. It supports VXLAN-based tenant segmentation, advanced telemetry with Cisco Tetration integration, and sub-microsecond latency. This deployment yields predictable multi-tenant isolation, real-time network analytics, and a 25% decrease in mean time to resolution (MTTR) for network issues, enabling SLA-backed service delivery at scale.
When a lab needs repeatable image and configuration staging before equipment enters service, NX-OS Power-On Auto Provisioning can automate software-image upgrades and configuration installation. Define the intended image and provisioning files before ordering, then include verification of the first-boot provisioning sequence in the staging plan.
When maintaining spares for an existing server rack, identify whether the installed equipment uses port-side intake or exhaust airflow. NXA-FAN-30CFM-B provides intake airflow, while NXA-FAN-30CFM-F provides exhaust airflow. Record the installed fan and power-module selections so the spare order specifies the required airflow configuration rather than condition alone.
When an existing data center centralizes switching for remote server racks, the N9300 family can manage 16 Cisco N2000 Series Fabric Extenders per switch. Each extender acts as a remote line card rather than an independently managed switch. Confirm the extender inventory and software compatibility before specifying the replacement hardware.
100G uplinks to the spine
N9K-C9372TX has fixed 40G uplinks and no removable uplink-card slot. A deployment requiring native 100G spine connections needs a different switch rather than an uplink-module upgrade.
Power delivery over endpoint Ethernet
N9K-C9372TX provides data connectivity without PoE output. Endpoints needing power through their Ethernet connection require separate power delivery or a PoE-capable switch.
Active Cisco hardware service coverage
Cisco support for N9K-C9372TX ended February 28, 2023. New sealed condition does not restart that service window; deployments requiring active Cisco support need a supported replacement.

N9K-C9372TX identifies the Nexus 9300 copper configuration with 48 100M/1/10GBASE-T access ports and six 40G QSFP+ uplinks. The complete model code distinguishes this hardware from fiber-access configurations. The hardware identifier does not establish an installed enhanced routing entitlement, so software licensing remains separate from the chassis identity.
N9K-C9372TX supports NX-OS command-line administration, Intelligent API remote procedure calls using JSON or XML, and Cisco DCNM graphical management. Command-line tools identify installed licenses and active feature usage. License installation requires the network-admin role, so administrative credentials and software entitlements need to be established during staging.
N9K-C9372TX is discontinued: end of sale was February 3, 2018, and Cisco support ended February 28, 2023. Routine software maintenance ended February 3, 2019. An order for new sealed hardware does not extend those milestones, and reseller condition must be distinguished from Cisco service eligibility.
New sealed and certified refurbished N9K-C9372TX units carry ORM warranties: up to 3-year extended coverage for new units and up to 1 year for certified refurbished units. Returns cover 30 days on every condition, terms apply. Cisco's original 1-year limited hardware warranty ended with support on February 28, 2023.
N9K-C9372TX includes default Layer 2 software; N93-LAN1K9 adds full OSPF, EIGRP, and BGP, while NX-OS-ES-XF and NX-OS-AD-XF are separate NX-OS license options. License key files are tied to the device host ID, so software entitlements must be specified separately from the hardware condition and chassis part number.
The Cisco N9372TX has six fixed 40G QSFP+ uplinks rather than a removable uplink-card bay. These interfaces connect toward aggregation or spine equipment while the copper interfaces serve attached systems. Optical compatibility and minimum software requirements must be checked for the selected connection; a modular uplink upgrade is unavailable.
Yes, N9K-C9372TX can run full OSPF, EIGRP, and BGP with N93-LAN1K9; these enhanced routing features are not included in the default Layer 2 configuration. Additional licenses enable Layer 3 IP unicast and multicast routing. The hardware PID alone does not confirm that optional routing entitlements accompany an order.
N9K-C9372TX supports two internal power modules and 1+1 redundancy with compatible AC, DC, or high-voltage supplies. UCSC-PSU-930WDC provides port-side intake DC power; N9K-PUV-1200W supports high-voltage AC/DC and both airflow directions. The included modules, supply quantity, power feed, and airflow selection must be confirmed for the individual order.
N9K-C9372TX has 48 copper 100M/1/10GBASE-T access ports, whereas N9K-C9372PX has 48 1/10G SFP+ access ports. Both models are discontinued. For existing-installation sparing, the TX model matches copper server cabling, while the PX model matches deployments built around SFP+ access connections rather than native copper interfaces.
N9K-C9372TX-E is a minor hardware revision of N9K-C9372TX with enhancements that are transparent in NX-OS mode and retain feature parity. Both models are discontinued, and their copper-access and fixed-uplink configurations match. Existing-installation buyers should distinguish the required hardware revision rather than treating the E suffix as a network-license tier.
N9K-C9372TX provides 48 copper access ports, while N9K-C93120TX provides 96. Both models are discontinued, and N9K-C93120TX also occupies two rack units rather than one. Existing-installation sparing for a single-unit chassis points to N9K-C9372TX; installations requiring the established 96-port configuration need the corresponding larger chassis identity.
The Cisco N9372TX provides 1440 Gbps of switching bandwidth and more than 1150 Mpps of forwarding performance. Bandwidth and packet rate describe different workload constraints. Traffic sizing therefore needs to consider both measurements, particularly where many small packets can increase processing demand without consuming the maximum interface bandwidth.
No, N9K-C9372TX provides Ethernet data connectivity without PoE output on its copper access ports. Attached equipment needs an independent power source. This makes the chassis a server-connectivity component rather than a power-delivery switch, and a requirement for Ethernet-powered endpoints cannot be satisfied by adding a different internal power module.
