N9K-C9372PX is a managed Nexus 9300 data center switch with 48 fixed 1/10 Gigabit Ethernet SFP+ access ports and six fixed 40 Gigabit Ethernet QSFP+ uplinks. Base NX-OS functionality places the switch at Layer 2+, with additional routing capabilities dependent on software entitlement. The 1U chassis serves top-of-rack and middle-of-row installations rather than powered endpoint access, and its optical interfaces do not supply PoE. Cisco Nexus 9372PX connects servers through compatible pluggable media while retaining a fixed uplink arrangement. Unlike the discontinued N9K-C9372TX, which uses copper server-facing connections, this model uses SFP+ access interfaces. The connector choice therefore matters when matching an existing rack's server adapters and cabling.
N9K-C9372PX price for new stock is $13,611.15. N9K-C9372PX refurb price is $199.50. N9K-C9372PX is in stock and available for next-day dispatch. (terms applied)

1440 Gbps switching capacity accommodates traffic across the access and uplink interfaces. More than 1150 Mpps forwarding capacity supports packet-intensive server traffic, while 537W maximum power consumption establishes the upper electrical planning figure. Static routing, switch virtual interfaces and HSRP are available without an additional feature license. N9K-C9372PX has 16 GB of memory for NX-OS operation. Hardware scale reaches 96000 MAC entries and 128000 longest-prefix-match routes, with actual operating limits dependent on the system forwarding mode. These hardware ceilings should not be treated as a guarantee for every software configuration. Four fans provide active cooling, with port-side intake and port-side exhaust configurations available. The 0°C to 40°C operating range requires a controlled installation environment. Supported electrical configurations include conventional AC, DC and high-voltage AC or DC supplies; the selected supply determines the applicable input range. Safety compliance includes UL 60950-1 and IEC 60950-1.
ORM Systems offers N9K-C9372PX new sealed or certified refurbished; refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configuration wiped to factory default.

Deploy the Cisco Nexus N9K-C9372PX as a leaf in a spine-leaf architecture to connect 48 1/10G SFP+ servers and aggregate traffic over 6 40G QSFP+ uplinks. Its non-blocking 1.28Tbps switching capacity and sub-microsecond latency optimize east-west traffic and maximize resource utilization. The result is predictable performance at scale, seamless workload mobility, and simplified management through Cisco NX-OS automation.
In high-frequency trading environments, the Cisco Nexus N9K-C9372PX delivers deterministic microsecond-level latency across 48 SFP+ 10G links and 6 QSFP+ 40G uplinks. Hardware-accelerated forwarding and granular QoS ensure minimal jitter and top-of-rack consolidation for trading servers. Traders achieve sub-5µs trade execution, enhanced throughput, and compliance with strict financial industry latency regulations.
Cloud service providers integrate the Nexus N9K-C9372PX into a Cisco ACI fabric to automate tenant segmentation over 48 10G access ports and 6 40G uplinks. Policy-driven provisioning and micro-segmentation enforce security and QoS per tenant while reducing manual configuration efforts. The outcome is rapid tenant onboarding, strict workload isolation, and reduced operational expenses through centralized orchestration.
When an existing server rack needs separate network attachments, a pair of switches can provide redundant connections to the servers. Treat the purchase as two independently configured units, not a hardware stack. Specify both chassis quantities and the required link media before issuing the purchase order.
When replacement hardware must be staged before installation, Power-On Auto Provisioning can load software images and configuration files during initial deployment. An automation workflow can also use the Intelligent API with JSON or XML. Specify the target image, provisioning files and management access requirements before ordering.
When an installed fleet spans several regions, spare purchasing needs a destination and quantity plan rather than a single central stock assumption. ORM Systems provides regional stock and RMA handling across the UK, EU, US and MEA. Record each delivery region and its allocated spare quantity before submitting the purchase order.
Native 25G server connections
The fixed SFP+ access interfaces operate at 1G or 10G. The chassis does not provide native 25G server connections or a removable access-card upgrade.
100G uplinks to the fabric
The six fixed QSFP+ uplinks are 40G interfaces. N9K-C9372PX has no removable uplink module bay through which to add native 100G uplinks.
Active Cisco hardware support
Cisco service and support ended February 28, 2023. Purchasing existing inventory, including a new sealed unit, does not reopen the manufacturer's ended support period.

N9K-C9372PX identifies the Nexus 9300 hardware model with 48 1/10G SFP+ access ports and six 40G QSFP+ uplinks. The complete hardware PID selects this fixed-port configuration rather than a paid routing package. Software entitlement must therefore be considered separately when specifying the unit.
N9K-C9372PX is managed through the NX-OS CLI using a serial console, SSH or Telnet, plus the Intelligent API over HTTP or HTTPS. The API accepts JSON or XML requests. Power-On Auto Provisioning supports initial software and configuration loading, so management access and staging requirements belong in the deployment specification.
N9K-C9372PX is discontinued, with end of sale on February 3, 2018 and last support on February 28, 2023. Software maintenance ended February 3, 2019. Existing inventory remains distinct from an actively supported Cisco product, and a later hardware purchase does not restart those lifecycle milestones.
ORM Systems offers N9K-C9372PX new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions have 30-day returns; terms apply. Cisco's original 1-year limited hardware warranty and support ended February 28, 2023. Refurbished units are inspected and bench-tested.
N9K-C9372PX includes base NX-OS functionality, with static routing available without a paid feature license. The hardware PID does not include NX-OS Essentials or NX-OS Advantage entitlement. Legacy N93-LAN1K9 Enterprise Services is discontinued, so verify existing software rights rather than assuming the hardware's condition determines its routing license.
N9K-C9372PX has six fixed 40G QSFP+ uplinks, separate from its 48 SFP+ access interfaces. These uplinks are built into the chassis rather than supplied through a removable network module. Specify compatible link media for the intended connections instead of ordering an uplink expansion card for this model.
No, Cisco Nexus 9372PX switches do not form a hardware stack through dedicated stacking ports. Paired deployment and virtual PortChannel functionality are different from a shared stacking backplane. Each chassis remains a separate switch, so a paired purchase requires separate configuration and the appropriate network connections between the units.
N9K-C9372PX supports N9K-PAC-650W for port-side intake airflow and N9K-PAC-650W-B for port-side exhaust airflow. The chassis supports two supply modules for operation and redundancy. Match the selected supply's airflow to the chassis cooling configuration, and confirm the included supply PIDs and quantities on the purchase order.
Cisco Nexus 9372PX consumes 210W typically and 537W at maximum. These are switch input-consumption figures, not the output rating of an installed power supply. Electrical planning should distinguish typical operation from the maximum figure and account for the supply configuration and available rack power before procurement.
Cisco Nexus 9372PX occupies 1U and measures 44 mm high, 439 mm wide and 571 mm deep. Depth and cable clearance therefore matter alongside vertical rack space. Confirm the rack's available installation depth and the required mounting hardware before placing an order for an existing cabinet.
N9K-C9372PX uses SFP+ access interfaces, while N9K-C9372TX uses copper BASE-T access interfaces. Both models are discontinued. The optical model suits existing installations using compatible pluggable link media; the copper model suits existing server attachments built around BASE-T connections, so match the connector arrangement rather than treating them as interchangeable.
N9K-C9372PX has fixed uplinks, while N9K-C9396PX uses a removable uplink module arrangement. Both models are discontinued. N9K-C9372PX suits like-for-like replacement in fixed-uplink installations; N9K-C9396PX belongs in legacy configurations that depend on a separately selected uplink module rather than the built-in uplinks of this model.
N9K-C9372PX provides 48 access ports, while N9K-C93120TX provides 96 access ports. Both models are discontinued. The smaller access-port count suits existing racks sized around 48 server-facing connections; the higher-density model addresses legacy installations requiring 96, with connector compatibility still requiring a separate check before substitution.
