N9K-C92304QC combines 56 40G QSFP+ downlinks with eight 40/100G QSFP28 uplinks in a full-width, 2U rack-mount chassis. The managed switch operates at Layer 2+ with its base NX-OS configuration and does not supply PoE endpoint power. Within the Nexus 9200 family of Cisco Nexus 9000 Series switches, this configuration connects fiber-attached servers to higher-speed fabric links. Its network interfaces are built into the chassis rather than supplied by removable uplink cards. The discontinued N9K-C92304QC-ZZ-PE differs by bundling a Layer 3 license. The base hardware configuration therefore needs to be distinguished from an enhanced routing bundle when specifying an existing mixed-speed data center installation.
N9K-C92304QC price for new stock is $17,014.20. N9K-C92304QC refurb price is $2,205.00. N9K-C92304QC is in stock and available for next-day dispatch. (terms applied)

6100 Gbps switching capacity supports concurrent traffic across the fiber interfaces, while forwarding exceeding 4800 Mpps provides the packet-processing rate for traffic sizing. 720W maximum AC input draw sets the upper power-planning figure rather than the output rating of an installed supply. A shared 30 MB buffer accommodates traffic bursts, with buffer monitoring available per port and per queue. N9K-C92304QC combines 16 GB of system memory with a 64 GB SSD for local software and configuration storage. Its forwarding resources support 92000 MAC entries and a default capacity of 6000 longest-prefix-match routes; the separate IP host-entry capacity is not a substitute for prefix-route capacity. Static routing, SVIs and HSRP are available without an additional license. Cisco Cloud Scale technology provides the forwarding foundation, and the Cisco Nexus 92304QC switch uses fiber network interfaces rather than copper Ethernet access ports.
Specify new sealed or certified refurbished N9K-C92304QC, the quantity and required configuration on the purchase order. Refurbished units are inspected and bench-tested for rated-speed links on every port, optics bay recognition, PSU status and fan status, with firmware verified and configuration wiped to factory default. ORM warranties provide up to a 3-year extended term for new units and up to 1 year for certified refurbished units; returns are 30 days on every condition, terms apply, and Cisco's original 1-year limited hardware warranty and service ended August 31, 2024. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement across UK, EU, US and MEA.

In a large enterprise data center supporting microservices and virtualization, the N9K-C92304QC acts as the spine switch in a leaf-and-spine topology. Its 56×40 Gbps QSFP+ links connect to leaf nodes while 8×100 Gbps QSFP28 ports handle inter-pod aggregation. This design delivers 3.2 Tbps of non-blocking throughput with sub-microsecond latency, driving faster east-west traffic, seamless EVPN-VXLAN automation, and on-demand workload scaling. Outcome: accelerated application performance, simplified NX-OS automation, and future-proof capacity for high-density workloads.
A cloud service provider deploys the N9K-C92304QC to build a multi-tenant fabric that segments traffic with VRFs and enforces QoS per customer. The switch’s 56×40 Gbps QSFP+ ports connect to tenant racks, and 8×100 Gbps QSFP28 uplinks tie into the provider’s core network. This configuration delivers granular bandwidth allocation, built-in micro-segmentation, and zero-touch provisioning via Cisco ACI or NX-API. Outcome: secure, SLA-driven performance for each tenant, rapid workload on-boarding, and simplified operations at scale.
Research institutions and financial trading firms use the N9K-C92304QC to interconnect GPU servers and compute nodes in AI/ML and HPC clusters. Its 8×100 Gbps QSFP28 ports provide high-bandwidth north-south connectivity, while 56×40 Gbps QSFP+ ports handle massive east-west data exchange between compute racks. The switch achieves sub-0.5 µs port-to-port latency and deterministic packet delivery under heavy loads. Outcome: faster model training and inference, real-time analytics, and the ability to scale compute fabric without compromising latency.
When an existing server estate still uses 10G fiber connections, ports 1 through 16 provide the breakout path from QSFP+ interfaces to 64 individual 10G connections. Breakout capability does not extend identically across every interface. Map the eligible ports and specify compatible breakout cabling before issuing the purchase order.
When a replacement batch must match cooling across several racks, select N9K-C9300-FAN3 for port-side intake or N9K-C9300-FAN3-B for port-side exhaust. Fan and supply airflow must agree, and supply input types cannot be mixed. Record the required airflow direction and power configuration for each rack before placing the order.
When hardware is purchased for configuration staging or traffic-analysis testing, the switch supports four active SPAN sessions and power-on autoprovisioning. Those capabilities provide distinct capture and provisioning options without changing the physical interfaces. Define the capture-session allocation and prepare the provisioning files before ordering the staging batch.
Active Cisco hardware support
Cisco service for N9K-C92304QC ended August 31, 2024. Projects requiring active Cisco support should evaluate N9K-C9364C-GX, the current successor reached through the discontinued N9K-C9364C.
100G connectivity on every interface
Only eight interfaces support 100G; the 56 QSFP+ downlinks are limited to 40G. N9K-C9364C-GX provides 64 40/100G QSFP28 interfaces for an all-100G connection requirement.
400G fabric connections
The fastest built-in interfaces are 100G. N9K-C93600CD-GX provides eight 400G interfaces alongside 28 100G interfaces, with a materially different connection layout from this model.

N9K-C92304QC identifies a fixed Nexus 9000 switch with 56 40G QSFP+ ports and eight 100G QSFP28 ports. N9K denotes the Nexus 9000 family, while C92304QC is the complete hardware model designation. The base PID carries no additional airflow, software-bundle or remanufacturing suffix; the digits are not a physical-port count.
N9K-C92304QC is managed through the NX-OS CLI using the console or remote SSH and Telnet sessions, with NX-API providing programmatic access over HTTP or HTTPS. The dedicated Ethernet management interface supports out-of-band access. Python scripting and power-on autoprovisioning provide additional automation paths for configuration and initial deployment.
N9K-C92304QC is discontinued: end of sale was August 29, 2019, and Cisco support ended August 31, 2024. Its original migration choices, N9K-C9332C and N9K-C9364C, are also discontinued. Their current successors are N9K-C93600CD-GX and N9K-C9364C-GX, respectively, rather than the original migration models.
ORM Systems offers N9K-C92304QC new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days on every condition; terms apply. Cisco's original 1-year limited hardware warranty and service ended August 31, 2024.
N9K-C92304QC requires no subscription for base NX-OS operation, including static routes, SVIs and HSRP. Enhanced routing uses the legacy perpetual N93-LAN1K9 Enterprise Services Package entitlement, which is no longer sold. A refurbished hardware order does not itself establish entitlement to paid routing features; specify the required software rights separately.
N9K-C92304QC has eight built-in QSFP28 interfaces supporting 40G or 100G connections, alongside 56 QSFP+ downlinks. No removable uplink card is needed to provide those interfaces. The link specification still needs to identify compatible transceivers and cabling for the required speed, connection distance and fiber arrangement.
Yes, N9K-C92304QC supports breakout connections on ports 1 through 16, providing 64 individual 10G connections from those interfaces. Breakout is not available identically on all 56 QSFP+ downlinks. Assign the server connections to eligible ports and specify supported breakout cabling rather than assuming every interface has the same conversion capability.
N9K-C92304QC provides 6100 Gbps switching capacity and forwarding exceeding 4800 Mpps. Those are separate bandwidth and packet-processing measurements, not interchangeable figures. The switch also has a 30 MB shared buffer, so traffic sizing should consider packet rate and burst behavior rather than using aggregate bandwidth alone.
Yes, Cisco Nexus 92304QC occupies 2U of rack space and measures 445 mm wide, 571 mm deep and 89 mm high. Supported mounting choices include NXK-ACC-RMK-2RU and N9K-C9300-RMK. Verify the rack arrangement, mounting hardware and clearance for interface cabling before specifying the installation configuration.
Two redundant supply modules power Cisco Nexus 92304QC, with AC, DC or HVAC/HVDC configurations. Options include NXA-PAC-650W-PI, NXA-PAC-650W-PE, UCSC-PSU-930WDC, UCS-PSU-6332-DC and N9K-PUV-1200W. Both supplies must have the same input type, and airflow must match the installed cooling configuration. Specify the input and airflow selections on the order.
N9K-C92304QC-ZZ-PE includes a Layer 3 license, whereas N9K-C92304QC is the base hardware PID without that routing bundle. Both models are discontinued. The bundled model suits an existing installation requiring its included routing entitlement; the base model suits buyers retaining separate software rights or using the base feature set.
N9K-C9272Q has 72 dedicated 40G QSFP+ interfaces, while N9K-C92304QC has 56 interfaces of that type. Both models are discontinued. N9K-C9272Q suits an existing layout requiring a larger bank of QSFP+ server connections; N9K-C92304QC suits a layout built around its smaller QSFP+ downlink bank and separate uplinks.
N9K-C9364C-GX supports 100G across 64 QSFP28 interfaces, while N9K-C92304QC supports 100G on only eight interfaces. N9K-C9364C-GX is the current successor reached through the discontinued N9K-C9364C. The successor suits an all-100G connection requirement; the retired model suits maintaining an existing mixed-speed installation without current Cisco service.
N9K-C92304QC-RF identifies Cisco-remanufactured hardware, whereas ORM certified refurbishment is a separate condition offering. The RF identifier does not add routing features to the base model. Paid capabilities still require the appropriate software entitlement, and Cisco service for this hardware ended August 31, 2024.
