N9K-C93128TX combines 96 copper 100M/1/10GBASE-T downlinks with a removable uplink bay in a 3RU data center switch. The base NX-OS configuration provides Layer 2 switching without PoE, serving separately powered servers rather than powered access endpoints. The N9300 chassis uses modular fiber uplinks instead of built-in optical uplink ports. Its uplink bay accepts QSFP+ or CFP2 configurations, with usable port counts determined by the installed card. Rack and blade servers with copper network interfaces are the primary endpoints, including top-of-rack, middle-of-row and end-of-row installations. Within the N9000 family, the discontinued N9K-C9396TX carries 48 copper downlinks for lower-density legacy configurations. Specify the complete hardware configuration rather than treating an uplink-capable chassis as an assembled switch.
N9K-C93128TX price for new stock is $34,534.50. N9K-C93128TX refurb price is $1,561.48. N9K-C93128TX is in stock and available for next-day dispatch. (terms applied)

2560 Gbps switching capacity establishes the chassis bandwidth ceiling for server-facing and aggregation traffic. Over 750 Mpps forwarding performance describes packet processing separately from that bandwidth figure. N9K-C93128TX provides 16 GB of memory for NX-OS operation, while its MAC table supports 96000 entries, subject to the selected forwarding mode. VLAN segmentation supports 4096 VLANs, with 507 RPVST instances available for spanning-tree operation. Management automation uses iAPI remote procedure calls with JSON or XML over HTTP or HTTPS. 853W maximum input draw sets the peak provisioning requirement for the power circuit rather than the output rating of an individual supply. The operating range is 0°C to 40°C. N9K-M6PQ, N9K-M6PQ-E and N9K-M12PQ do not support four-way 10G breakout, so their 40G connections cannot be divided into four independent server links.
New sealed and certified refurbished N9K-C93128TX orders carry ORM warranties of up to a 3-year extended term and up to 1 year, respectively; Cisco's original 1-year limited hardware warranty ended with Cisco service on October 31, 2022. Certified refurbished units are inspected and bench-tested, including module bay recognition, with firmware verified and configurations wiped to factory default; both conditions have 30-day returns, terms apply. Specify the condition and quantity on the purchase order for this switch. POs are accepted, with Net-30 for government; enterprise and volume buyers can consolidate required quantities on the PO.

In a hyperscale data center, the N9K-C93128TX-Nexus 9300 with 96p 100M/1/10G-T server ports and 8p 40G QSFP uplinks serves as a high-density leaf switch. It delivers 1.28 Tbps of spine connectivity, sub-microsecond latency, and native VXLAN support for east-west traffic. The result is a scalable, low-latency fabric that simplifies expansion and accelerates cloud-scale workloads.
Large enterprises deploy the N9K-C93128TX-Nexus 9300 as a unified campus aggregation switch, leveraging 96 flexible 100M/1/10G-T access ports and 8p 40G QSFP uplinks to core and data center. This architecture supports high-bandwidth services—VoIP, video conferencing and IoT—while centralizing QoS policies and security. The outcome is streamlined operations, enhanced throughput, and predictable end-to-end performance across the campus.
Cloud and service-provider environments integrate the N9K-C93128TX-Nexus 9300 into Cisco ACI fabrics to deliver automated, segmented multi-tenant networks. Ninety-six 1/10G-T ports host tenant VLANs/VRFs and eight 40G QSFP uplinks provide high-capacity spine interconnects. The deployment enables zero-touch provisioning, consistent policy enforcement and robust tenant isolation, driving operational efficiency and strong security posture.
When preparing a first-time deployment, Power-On Auto Provisioning can upgrade the software image and install configuration files before the N9300 enters service. Keep staging separate from the production change window, and specify the intended image, configuration delivery method and acceptance checks before issuing the purchase order.
When purchasing replacement inventory for an existing N9K-C93128TX estate, align the spare quantity with the organization's RMA process rather than a new deployment plan. ORM provides RMA with advance replacement and regional stock and RMA coverage across the UK, EU, US and MEA. Specify the required region and spare quantity on the PO.
Active Cisco service coverage
N9K-C93128TX Cisco service ended October 31, 2022. The current migration endpoint is N9K-C93216TC-FX2, retaining 96 copper downlinks in a different, 2RU chassis.
Four-way 10G uplink breakout
N9K-M6PQ, N9K-M6PQ-E and N9K-M12PQ do not provide four-way 10G breakout on N9K-C93128TX. Each 40G connection must remain a single link rather than four independent connections.
Enhanced routing without additional licensing
N9K-C93128TX does not include an Enhanced L3 entitlement in its base configuration. Full OSPF, EIGRP and BGP require N93-LAN1K9 rather than the hardware PID alone.

N9K-C93128TX identifies a Nexus 9000-family switch with 96 copper 100M/1/10GBASE-T downlinks and a required uplink module. N9K identifies the product family, while C93128TX identifies this hardware model. The base part number does not include the Enhanced L3 bundle designation; specify routing entitlement separately.
The N9300 series runs NX-OS and supports iAPI management through JSON or XML remote procedure calls over HTTP or HTTPS. A separate ACI operating mode provides policy-based systems management. Specify the intended operating mode and automation requirements before staging rather than treating the two deployment approaches as interchangeable.
N9K-C93128TX supports N9K-M6PQ and N9K-M6PQ-E with six active 40G ports, N9K-M12PQ with eight active 40G ports, or N9K-M4PC-CFP2 with two active 100G ports. An uplink card is required for normal operation. Specify the card by PID because its physical connector count can exceed its active port count.
N9K-C93128TX uses additional software licenses for functions beyond its default Layer 2 security and management capabilities. N93-LAN1K9 provides Enhanced L3, including full OSPF, EIGRP and BGP; NX-OS-ES-XF Essential and NX-OS-AD-XF Advantage are additional options. Specify the required entitlement on the order rather than assuming the chassis includes it.
N9K-C93128TX accepts N9K-PUV-1200W for HVAC/HVDC input, UCSC-PSU-930WDC for port-side-intake DC power, or UCS-PSU-6332-DC for port-side-exhaust DC power. The chassis uses two supplies in a 1+1 arrangement. Specify the input method and airflow configuration before ordering replacement hardware for an existing installation.
N9K-C93128TX reached end of sale on October 30, 2017, and its last date of Cisco support was October 31, 2022. Cisco service has ended. Its original migration option, N9K-C93120TX, is also discontinued; the forward migration chain now ends at the available N9K-C93216TC-FX2.
ORM offers N9K-C93128TX new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's original 1-year limited hardware warranty no longer provides service: Cisco support ended October 31, 2022.
N9K-C93128TX carries 96 copper access ports, while N9K-C9396TX carries 48; both support 100M/1/10GBASE-T connections. Both models are discontinued. For legacy replacement inventory, N9K-C93128TX suits an existing higher-density installation, while N9K-C9396TX suits an estate already standardized on the lower-density chassis.
N9K-C93128TX-BA-L3 includes an Enhanced L3 designation, while N9K-C93128TX is the base hardware PID without that bundled entitlement. Both models are discontinued. The base model suits legacy replacement orders with separately specified software, while N9K-C93128TX-BA-L3 suits an existing configuration requiring the Enhanced L3 bundle.
N9K-C93216TC-FX2 has twelve built-in 40/100G QSFP28 uplinks, while N9K-C93128TX requires a separate uplink module. N9K-C93216TC-FX2 is the current migration endpoint. The discontinued N9K-C93128TX serves like-for-like legacy replacement requirements; N9K-C93216TC-FX2 suits replacement purchases requiring integrated uplinks and a currently available model.
