When it comes to building a high-performance, scalable, and secure network infrastructure, the Cisco Catalyst 9500 Series Switches stand out as a top contender. These switches are engineered to serve as core and aggregation layer solutions, offering not just reliability but also forward-looking capabilities that align with modern enterprise demands. Whether you’re expanding your existing network or designing a new architecture from the ground up, understanding what the Catalyst 9500 brings to the table is essential.
One of the key strengths of this series is its support for redundant power supplies and modular fans, which are critical for maintaining uptime and enabling hassle-free maintenance. But it doesn’t stop there—the real versatility lies in the wide range of downlink port configurations. Depending on the model, you can choose from 100G, 40G, 25G, or 10G capable ports, allowing fine-tuned alignment with your bandwidth needs and future growth plans.
Available Models and Configurations
The Catalyst 9500 family includes multiple models, each catering to different use cases. Below is a detailed overview of the base and bundle models.
Base Models Overview
The C9500-12Q and C9500-24Q are ideal for environments where high-density 40G connectivity is a priority. With 12 and 24 QSFP+ ports respectively, they are well-suited for aggregation roles in mid- to large-sized networks.
For those requiring a blend of high-speed access and uplink flexibility, the C9500-16X and C9500-40X offer 10G SFP/SFP+ downlinks and support optional network modules. These modules allow you to add uplink ports such as 8x10G or 2x40G, making the switches adaptable to changing network topologies.
The high-performance segment includes the C9500-32C and C9500-32QC, which support 100G connectivity—a necessity for data centers and core network layers. Additionally, the C9500-24Y4C and C9500-48Y4C come with 1G/10G/25G SFP28 ports and fixed 100G uplinks, striking a balance between access and high-speed aggregation.
Bundle Options for Quick Deployment
Cisco also offers pre-configured bundles that simplify procurement and deployment. The C9500-16X-2Q and C9500-40X-2Q, for instance, include built-in 40G uplink modules, while the C9500-24X and C9500-48X come with extra 10G uplinks. These are excellent for organizations looking to minimize setup time and maximize readiness.
Power Supply Specifications
Each switch in the series is designed with two power supply slots, providing redundancy and flexibility. Depending on your infrastructure’s power environment, you can opt for either AC or DC power modules. It’s important to note that the chassis ships with one power supply pre-installed; the second slot may include a blank cover if only one supply is ordered. Below are the supported power options for each model.
The C9500-12Q is compatible with a 950W AC power supply, while the C9500-24Q, C9500-16X, C9500-40X, and C9500-32C support more robust 1600W AC or DC options. The C9500-32QC uses 650W AC or 930W DC, and the C9500-24Y4C and C9500-48Y4C are also designed for high efficiency with similar power variants.
Uplink Connectivity and Expandability
A major advantage of the Catalyst 9500 Series is its support for modular and fixed uplink options. Select models allow the use of network modules that add 10G or 40G uplink ports, while others come with fixed 100G/40G QSFP28 uplinks. This ensures that your network remains scalable as bandwidth demands increase.
Advanced Features for Modern Networks
Beyond throughput and hardware specs, these switches incorporate advanced capabilities essential for today’s networked environments. With features like Encrypted Traffic Analytics (ETA), MACSec-256 encryption, and Trustworthy Systems, the series provides enhanced security from the ground up.
Furthermore, the Catalyst 9500 supports IoT integration and policy-based automation through Cisco’s SD-Access framework, allowing seamless management from edge devices to cloud resources. For administrative access, the switches include both RJ-45 and USB Mini-Type B console ports. Selected models also support SATA SSD storage, opening the door to hosting containerized applications directly on the switch—an increasingly valuable capability in distributed architectures.
