The Cisco Nexus® 9000 Series Switches operate in one of two modes – Cisco Application Centric Infrastructure (Cisco ACI™) or Cisco NX-OS. In Cisco ACI mode, these switches provide a turnkey, fully automated, policy-based architecture to design and manage data center fabrics. In Cisco NX-OS mode, these switches provide the capability to use foundational layer 2/3 technologies, as well as modern technologies such as VXLAN, with a Border Gateway Protocol‒Ethernet VPN (BGP-EVPN) control plane, Segment routing, Multiprotocol Label Switching (MPLS), and automation via NX-APIs.

Product Details
The Cisco Nexus9000 Series Switches provides features and benefits:
* High performance
The Cisco Nexus 9500 Series switch delivers nonblocking performance at a latency of 5 microseconds or less at 400-, 100-, 50-, 40-, 25-, 10-, and 1-Gigabit Ethernet speeds. This enables customers to build robust and scalable high-speed fabrics that can support several thousands of high-speed access ports.
* Telemetry
The Cisco Nexus 9500 Series switches support extensive switch and flow telemetry capabilities that provide extensive real-time visibility into switch and fabric states.
* High-density 1-, 10-, 25-, 40- and 50-Gigabit Ethernet access configuration
Organizations can transition from low-speed (100-Megabit Ethernet and 1-Gigabit Ethernet) server access designs to high-speed (1-, 10-, 25-, 40-, and 50-Gigabit Ethernet) server access designs with the same port density.
* High-density 10-, 40-, 100- and 400-Gigabit Ethernet aggregation and spine configuration
The Cisco Nexus 9500 Series Switches help organizations transition from 1- and 10-Gigabit Ethernet infrastructure to 10-, 40-, 100-, and 400-Gigabit Ethernet infrastructures to support the increased bandwidth demands of scale-out, multinode application environments. The compatibility of 400-Gigabit Ehternet QSFP-DD modules, 100-Gigabit Ethernet QSFP28 modules, and 40-Gigabit Ethernet QSFP+ modules enables the migration and coexistence of 40-, 100- and 400-Gigabit Ethernet ports in the fabric.
* High availability, reliability, and scalability
The Cisco Nexus 9500 Series Switches are designed with redundant supervisors, system controllers, power supplies, and fan trays, which eliminate any single point of failure in the chassis. These switches also support up to 6 fabric modules, which provide redundancy and graceful degradation of switching capacity in the event of fabric module failures. All transceivers are pluggable to support the highest possible Mean Time Between Failure (MTBF) for the switch.
* Designed for the future
The Cisco Nexus 9500 Series Switches are designed for future expansion with the capability to support higher speed ports and more bandwidth.
* Power efficiency
The Cisco Nexus 9500 Series Switches are the first switch chassis designed without a midplane. The line cards and fabric modules connect directly. This revolutionary design provides optimal front-to-back airflow and helps the switch operate with less power. In addition, all Cisco Nexus 9500 Series switch power supplies are rated at or higher than 80PLUS Platinum for AC inputs and equivalent efficiency for DC inputs.
The typical power consumption per 10-Gigabit Ethernet port is less than 3.5 watts (W).
The typical power consumption per 40-and 100-Gigabit Ethernet port is less than 14W and 22W respectively.

Frequently Asked Questions
What is the primary architectural advantage of the Cisco Nexus 9516 chassis? +
The Nexus 9516 is a modular switch chassis designed for high-density 10/40/100GbE data center environments. Its primary advantage is the 16-slot linecard capacity, which provides massive scalability and throughput, allowing network architects to consolidate core and aggregation layers into a single, high-performance modular system capable of supporting evolving spine-leaf network fabrics.
How many linecard slots does the N9K-C9516 provide for port density? +
The N9K-C9516 chassis is engineered with 16 horizontal linecard slots. This configuration offers exceptional flexibility, allowing IT teams to mix and match various interface modules to meet specific bandwidth requirements while maintaining high port density for large-scale enterprise data center deployments and cloud provider infrastructures.
Is the Cisco Nexus 9516 suitable for high-performance leaf-spine network architectures? +
Absolutely. The Nexus 9516 is designed to serve as a high-capacity spine switch in modern leaf-spine topologies. Its modular design supports low-latency, non-blocking performance, which is essential for handling the East-West traffic patterns common in virtualized data centers and large-scale, multi-tenant cloud environments.
What type of power and cooling redundancy should I plan for with the N9K-C9516? +
Because the N9K-C9516 is a high-performance modular system, it requires a robust power and cooling strategy. The chassis is designed for N+1 or N+N power redundancy to ensure maximum uptime. You must ensure your data center rack infrastructure can accommodate the necessary power modules and airflow requirements for optimal thermal management.
Does the Nexus 9516 support programmable network automation tools? +
Yes, the Cisco Nexus 9516 supports advanced programmability, including Cisco NX-API, Python scripting, and integration with common orchestration platforms like Ansible or Puppet. This enables network engineers to automate configuration tasks, enhance visibility, and accelerate the deployment of complex data center network services across their infrastructure.
How does the N9K-C9516 handle scalability for future bandwidth requirements? +
The modular architecture of the N9K-C9516 allows for seamless upgrades. As your bandwidth needs grow, you can populate the remaining linecard slots or transition to higher-speed interface modules without requiring a full chassis replacement. This provides long-term investment protection and allows for a 'pay-as-you-grow' expansion strategy within your enterprise core.
What management interfaces are available on the Cisco Nexus 9516? +
The chassis features dedicated management ports, including standard RJ-45 and SFP+ console ports for out-of-band management. This enables administrators to monitor and manage the switch through the Cisco NX-OS command-line interface, ensuring comprehensive control over system operations and troubleshooting processes during critical maintenance windows.
Can the N9K-C9516 be deployed in a Cisco ACI environment? +
The Nexus 9516 is fully compatible with Cisco Application Centric Infrastructure (ACI). By running the switch in ACI mode, you can leverage centralized, policy-based automation and application-aware networking. This integration simplifies management, enhances security through micro-segmentation, and improves operational efficiency across your entire software-defined data center.
