N9K-C9372TX-E-B18Q is a two-switch data center bundle built around the Nexus 9372TX-E, with eight QSFP-40G-SR-BD transceivers included. Each chassis provides 48 copper ports supporting 100 Mbps, 1G and 10G, alongside six fixed 40G QSFP+ uplinks. The server-facing ports do not supply PoE, and the uplink connections require no removable expansion card. Base NX-OS operation provides Layer 2+ functionality, including static routing, rather than an advanced routing entitlement implied by the bundle name. The 1U Nexus 9300 hardware serves copper-connected rack and blade servers in top-of-rack or middle-of-row arrangements. The discontinued N9K-C9372PX-E-B18Q bundle instead uses SFP+ server-facing interfaces, distinguishing fiber server connections from this bundle's 10GBASE-T connections. Both are legacy purchasing options rather than current Cisco-supported equipment.
N9K-C9372TX-E-B18Q price for new stock is $51,975.00. N9K-C9372TX-E-B18Q refurb price is $30,448.95. N9K-C9372TX-E-B18Q is in stock and available for next-day dispatch. (terms applied)

1440 Gbps switching capacity per chassis supplies the internal bandwidth for server and upstream traffic, while more than 1150 Mpps forwarding performance provides the corresponding packet-processing rating. 694W maximum input draw per chassis establishes the electrical planning ceiling rather than the typical operating load. A 96000-entry MAC address table supports endpoint learning, with achievable scale dependent on the forwarding mode. N9K-C9372TX-E-B18Q equips each chassis with 16 GB of memory and a 64 GB SSD for system operation and local storage. Static routing supports intersubnet forwarding without introducing a dynamic routing protocol. Four fans provide active cooling, and operation within 0°C to 40°C requires a controlled equipment-room environment. NX-OS uses modular software processes so that a process failure can be isolated instead of requiring every software function to restart together. Native 100G uplinks are absent; the built-in upstream interfaces stop at 40G.
ORM Systems offers N9K-C9372TX-E-B18Q new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units; Cisco's original 1-year limited hardware warranty and service ended October 31, 2023. Certified refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links, clean boot and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify condition and quantity on the PO; 30-day returns apply to every condition, subject to terms. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement across UK, EU, US and MEA.

When a lab must reproduce an existing data center environment, operating mode matters before configuration begins. NX-OS standalone operation and ACI policy-based operation are separate deployment choices, while POAP automates image installation and configuration loading. Specify the required operating mode, software image and startup configuration before the PO.
When several sites use different hot-aisle and cold-aisle layouts, the airflow build must follow each rack rather than a common purchasing description. NXA-FAN-30CFM-B provides port-side intake; NXA-FAN-30CFM-F provides port-side exhaust. Specify matching power-supply airflow and the required fan PID for every chassis before the PO.
Active Cisco support coverage
Cisco hardware support and security support ended October 31, 2023. The bundle cannot satisfy a purchase requirement for active manufacturer service or ongoing security maintenance.
Native 100G upstream connections
Uplinks stop at 40G on the six fixed QSFP+ ports, and the chassis has no removable uplink-card slot for higher-speed expansion.
SFP+ interfaces for server connections
Each chassis uses copper 10GBASE-T server-facing ports, not SFP+ downlinks. Fiber-connected server requirements cannot be met by inserting transceivers into the RJ-45 interfaces.

N9K-C9372TX-E-B18Q identifies a Nexus 9000 bundle of two copper-port Nexus 9372TX-E switches and eight QSFP-40G-SR-BD transceivers. N9K denotes the Nexus 9000 family; C9372TX identifies the switch model; E is its minor hardware revision; B18Q identifies the two-switch optical bundle, not a license tier.
N9K-C9372TX-E-B18Q is managed through the NX-OS CLI and Intelligent API in standalone operation, or through ACI policy-based management. The API carries JSON or XML remote procedure calls over HTTP or HTTPS. Specify the intended operating mode before preparing the software image and configuration for either chassis.
N9K-C9372TX-E-B18Q is discontinued: end of sale was October 30, 2018, and Cisco support ended October 31, 2023. Software maintenance ended October 30, 2019. The bundle is therefore a legacy-hardware purchase, not an option for requirements that depend on active Cisco service or continuing security support.
ORM offers N9K-C9372TX-E-B18Q new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are accepted for 30 days in either condition; terms apply. Cisco's original 1-year limited hardware warranty and service ended October 31, 2023.
N9K-C9372TX-E-B18Q does not encode an advanced network license; base NX-OS includes static routing and HSRP. Advanced routing historically used N93-LAN1K9, which is discontinued. NX-OS Essentials and NX-OS Advantage are separate software options. Identify valid entitlements for both chassis rather than treating the bundle suffix as an included routing license.
N9K-C9372TX-E-B18Q contains two switches with six fixed 40G QSFP+ uplinks per chassis and includes eight QSFP-40G-SR-BD transceivers. The uplinks are built in rather than provided by an expansion card. Match the quoted optical contents to both ends of the intended links before specifying additional transceivers.
The Nexus 9372TX-E supports two internal power-supply positions for 1+1 redundancy, with the populated supply configuration confirmed on the order. Available choices include N9K-PUV-1200W for high-voltage AC or DC and UCSC-PSU-930WDC for DC. Power-supply airflow must match the fan configuration for each chassis.
The Nexus 9372TX-E provides 1440 Gbps switching capacity and more than 1150 Mpps forwarding performance per chassis. Evaluate traffic on each switch separately when planning server-facing and upstream links. The two chassis do not combine into a single chassis-level forwarding resource merely because they share one bundle ordering number.
The Nexus 9372TX-E uses a 1U rack-mount chassis measuring 44 mm high, 439 mm wide and 571 mm deep. Reserve rack space for both chassis in the bundle and confirm rack compatibility before ordering. Airflow direction must match the intended hot-aisle and cold-aisle arrangement.
N9K-C9372TX-E-B18Q uses copper 10GBASE-T server ports, while N9K-C9372PX-E-B18Q uses 1G/10G SFP+ server ports. Both bundles contain two switches and eight QSFP-40G-SR-BD transceivers, and both are discontinued. The TX bundle matches copper-connected server estates; the PX bundle matches existing fiber or SFP+ server connections.
N9K-C9372TX-E-B18Q is a two-switch bundle with eight QSFP-40G-SR-BD transceivers, while N9K-C9372TX-E= is a single spare chassis excluding the accessory kit, power supplies and fans. Both ordering forms are discontinued. The bundle addresses paired-switch purchasing; the spare addresses replacement-chassis requirements where the excluded components are separately accounted for.
