N9K-C9372PX-E provides 48 fixed 1/10G SFP+ downlinks and six fixed 40G QSFP+ uplinks in a 1U data center chassis. The interfaces connect rack servers, blade infrastructure, and aggregation networks without an additional uplink card. The Nexus 9300 configuration is non-PoE and uses pluggable media rather than built-in copper access connections. Compared with the discontinued N9K-C9372TX-E, its server-facing connections use SFP+ instead of 100M/1/10GBASE-T. Within the Nexus 9000 family, this model supports existing fiber-connected server environments and fixed 40G fabric connections. Base NX-OS includes static routing, making the unexpanded software configuration Layer 2+ rather than a fully licensed dynamic-routing configuration.
N9K-C9372PX-E price for new stock is $10,393.95. N9K-C9372PX-E refurb price is $231.00. N9K-C9372PX-E is in stock and available for next-day dispatch. (terms applied)

1440 Gbps switching capacity supports the fixed interface configuration, while over 1150 Mpps forwarding capacity addresses packet processing across those connections. N9K-C9372PX-E has 16 GB of DRAM and a 64 GB SSD for local storage; the SSD capacity is separate from a flash-memory specification. Hardware maxima reach 96000 MAC entries and 128000 longest-prefix-match routes, with actual scale dependent on forwarding mode. Static routes, switch virtual interfaces, and HSRP are available without an additional feature license. Management supports console access, CLI sessions over SSH or Telnet, NETCONF/XML, NX-API, and the DCNM client. 537W maximum input draw provides the upper figure for electrical planning rather than the output rating printed on a selected supply. Four fans provide active cooling, with intake or exhaust components selected to match the rack airflow arrangement. Native uplinks do not provide 100G connectivity.
Select N9K-C9372PX-E in new sealed or certified refurbished condition, and specify the required hardware contents before placing the order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. ORM's new-unit warranty is up to a 3-year extended warranty, certified refurbished coverage is up to 1 year, and every condition includes 30-day returns, with terms applying. Submit the requested quantities and condition on the purchase order for enterprise or volume requirements; PO orders are accepted, and Net-30 is available for government.

In a managed services provider environment, the N9K-C9372PX-E Nexus 9300 with 48×10G SFP+ and 6×40G QSFP+ serves as the spine switch in a leaf-spine topology. It aggregates traffic from dozens of leaf switches hosting virtualized compute and storage nodes for multiple tenants. Benefit: delivers sub-microsecond latency, line-rate forwarding, and predictable east-west throughput, enabling SLAs with 99.999% uptime and rapid tenant provisioning.
A flagship university deploys the N9K-C9372PX-E Nexus 9300 as its campus core switch to interconnect lab clusters, lecture hall Wi-Fi access points, and research storage arrays. Utilizing 48×10G SFP+ for edge aggregation and 6×40G uplinks to data center resources, it ensures deterministic bandwidth for large data transfers. Outcome: accelerates scientific computation workflows by 2×, supports 50,000 concurrent users, and simplifies network segmentation with 1,000+ VXLANs.
In a stock exchange’s co-location facility, the N9K-C9372PX-E Nexus 9300 forms the backbone fabric connecting trading servers, market data feeds, and risk‐management appliances. Its 48×10G SFP+ ports link to individual trading racks, while 40G QSFP+ trunks provide ultra-fast aggregation to the exchange core. Benefit: achieves sub-200 ns port-to-port latency, deterministic packet forwarding, and on-the-fly QoS, driving faster trade execution and improved P&L margins.
When an existing rack design depends on remote interfaces rather than additional standalone switches, the Nexus 9300 supports 16 Nexus 2000 Fabric Extenders per switch. Identify the installed extender inventory and its software compatibility before treating attachment capacity as available expansion. Specify the required connections and compatibility checks before the purchase order.
When a replacement needs preparation before a maintenance window, license installation requires an account with the network-admin role. Separate configuration staging from the production cutover and identify who will validate entitlement installation on the allocated unit. Specify the staging account, required license files, and acceptance checks before the purchase order.
When an installed fleet needs identical replacement hardware, regional stock and RMA arrangements cover the UK, EU, US, and MEA. Keep the spare-unit requirement separate from capacity expansion and identify the receiving region for each allocation. Specify condition, quantities, delivery region, and advance-replacement RMA requirements before the purchase order.
25G server-facing fiber connections
N9K-C9372PX-E downlinks stop at 10G. N9K-C93180YC-FX3 provides 48 1/10/25G downlinks for a server refresh that requires native 25G connectivity.
Active Cisco hardware service coverage
N9K-C9372PX-E hardware service and vulnerability support ended October 31, 2023. N9K-C93180YC-FX3 is the current forward migration target rather than another discontinued intermediate model.

N9K-C9372PX-E identifies the Nexus 9300 chassis with 48 1/10G SFP+ downlinks and six fixed 40G QSFP+ uplinks. The -E version is a minor hardware revision of N9K-C9372PX, with feature parity in NX-OS mode. The complete PID identifies the configuration; its ending does not identify an included routing license.
N9K-C9372PX-E is managed through the NX-OS CLI over console, SSH, or Telnet, plus NETCONF/XML, NX-API over HTTP or HTTPS, and the DCNM client. The Nexus 9300 family also supports ACI operation for policy-based management. Specify the intended operating mode and management integration before preparing the replacement configuration.
N9K-C9372PX-E is discontinued: end of sale was October 30, 2018, and the last date of Cisco support was October 31, 2023. Vulnerability and security support also ended on October 31, 2023. A reseller purchase does not restart those milestones or restore Cisco service eligibility for the hardware.
ORM Systems offers N9K-C9372PX-E new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions have 30-day returns; terms apply. Cisco's original 1-year limited hardware warranty and service availability ended no later than October 31, 2023.
N9K-C9372PX-E includes base NX-OS functions; additional functions require separate entitlements. Paths include legacy N93-LAN1K9, now discontinued; NX-OS Advantage perpetual; DCN Advantage perpetual; and DCN Essentials or Advantage subscriptions with a 3-year minimum and 5-year or 7-year options. Perpetual tier licenses are not portable between devices. Confirm entitlement compatibility with the installed release.
The Nexus 9372PX-E provides six fixed 40G QSFP+ uplink connections, alongside its 48 server-facing SFP+ ports. No removable uplink card is required to expose those six connections, and the chassis does not provide native 100G uplinks. Specify compatible media and the required connection distances when assembling the purchase order.
Yes, N9K-C9372PX-E supports two power-supply positions for optional redundancy. AC choices include N9K-PAC-650W for port-side intake and N9K-PAC-650W-B for port-side exhaust. Supply selection must match the cooling direction. Specify the required supply quantity and airflow orientation rather than assuming that a second supply accompanies every chassis order.
N9K-C9372PX-E provides 1440 Gbps switching capacity and over 1150 Mpps forwarding capacity across its fixed interfaces. Those figures describe different performance measures: bandwidth and packet forwarding. Use both when reviewing a replacement against the existing traffic profile, rather than treating the switching-capacity figure as a packet-rate specification.
Base NX-OS on the Nexus 9300 includes static routes, switch virtual interfaces, and HSRP without an additional feature license. OSPF, BGP, EIGRP, and other advanced routing functions belong to additional license packages. A hardware routing-scale maximum does not establish that those dynamic-routing functions are included with the chassis purchase.
N9K-C9372PX-E uses 1/10G SFP+ downlinks, while N9K-C9372TX-E uses 100M/1/10GBASE-T copper downlinks. Both models are discontinued. The PX-E configuration fits an existing pluggable-media server connection plan; the TX-E configuration fits an installed copper connection plan. Match the replacement to the existing interface media rather than treating these PIDs as interchangeable.
N9K-C9372PX-E= is the spare chassis PID that excludes the accessory kit, power supplies, and fans; N9K-C9372PX-E is the base configuration PID. Both are discontinued. The spare variant suits a repair plan that already has those components, while a base configuration order should explicitly identify the complete required hardware contents.
N9K-C93180YC-FX3 provides six 40/100G uplinks, while N9K-C9372PX-E provides six fixed 40G QSFP+ uplinks. N9K-C9372PX-E is discontinued, whereas N9K-C93180YC-FX3 is the current forward migration target. Retaining the older configuration addresses an existing 40G connection plan; the newer model addresses a refresh requiring native 100G fabric connections.
