N9K-C93128TX Cisco Nexus 9300 Switch with 96p 1/10GBASE-T & 1x Uplink Module Slot
Cisco Nexus N9K-C93128TX 9300 Series 10GBASE-T Switch
High-Density 10GbE Copper Aggregation for Modern Data Centers
The Cisco Nexus N9K-C93128TX is a high-density, low-latency data center switch engineered for modern Top-of-Rack (ToR) and leaf-spine architectures. Designed to support bandwidth-intensive workloads, virtualization, and cloud-scale environments, this 3RU fixed-configuration switch delivers exceptional performance, scalability, and operational flexibility for enterprise and hyperscale data centers.
Featuring 96 fixed 1/10GBASE-T RJ-45 ports, the N9K-C93128TX enables seamless migration from 1G to 10G Ethernet using existing Cat6a/Cat7 copper cabling - eliminating costly fiber upgrades while supporting high-density server connectivity. The switch includes a modular uplink slot supporting high-speed expansion modules, enabling 40G and 100G uplinks for spine connectivity and high-bandwidth aggregation.
With a switching capacity of 2.56 Tbps and a forwarding rate of 750 Mpps, this Nexus switch delivers ultra-low latency performance ideal for virtualization clusters, cloud applications, and high-performance computing environments. It can operate in Cisco NX-OS mode for traditional networking or Cisco ACI mode for automated, policy-based data center fabrics.
Advanced telemetry and analytics capabilities, including Cisco Tetration Analytics and streaming telemetry, provide deep visibility into traffic flows and network performance. High availability is ensured through N+1 redundant hot-swappable power supplies and fan modules, while flexible airflow options support efficient data center cooling strategies.
Built for scalable, automated, and high-performance data center networking, the Cisco Nexus N9K-C93128TX is an ideal solution for enterprises seeking reliable, high-density 10G copper switching with future-ready uplink expansion.

FAQs:
Q1. Does this switch support 1G speeds on the copper ports?
Yes. The 96 fixed ports are auto-sensing 100M/1G/10GBASE-T, allowing you to connect legacy 1G servers and upgrade to 10G when ready.
Q2. Which uplink modules are compatible with the N9K-C93128TX?
Common modules include the N9K-M6PQ (6 x 40G QSFP+), N9K-M12PQ (12 x 40G QSFP+), and the N9K-M6PQ-E. Note that 100G modules may require specific software and supervisor combinations.
Q3. Can this switch be used in an ACI Leaf-Spine architecture?
Yes. The N9K-C93128TX is designed to function as a Leaf switch in a Cisco ACI environment, providing connectivity to servers and integrated appliances.
Q4. What type of cabling is recommended for the 10G ports?
For 10Gbps speeds over the full 100-meter distance, Category 6a (Cat6a) or Category 7 (Cat7) cabling is required. Standard Cat6 may work at shorter distances (up to 37–55 meters).
Q5. Is the software license included?
The hardware includes the base software, but advanced features like ACI or certain Layer 3 protocols may require additional licenses, such as the Nexus 9300 Advantage or Essentials licenses.
