Models and specifications

A fully assembled Cisco C9350 Series switch includes the fixed chassis, an optional modular uplink network module, three modular fan units, at least one field-replaceable power supply, and associated accessories.

Chassis

Cisco C9350 Series Smart Switches are fixed access platforms designed for campus and branch networks. They provide high-density Gigabit and Multigigabit copper downlinks with advanced PoE, as well as modular uplinks for high-speed Ethernet connectivity.

Powered by the Silicon One A100/L application-specific integrated circuit (ASIC), the C9350 delivers up to 1.3 Tbps throughput and 1.5 billion packets per second. It supports up to 256,000 IPv4 routes, 64,000 MAC addresses, and 128,000 HCAM entries for ACLs and flow data (NetFlow), enabling scale for large enterprise deployments. Flexible pipelines, programmable tables, and scalable buffering support evolving network requirements.

To learn more about Cisco Silicon One ASICs on Cisco C9000 Series Smart Switches, please refer to the Cisco Silicon One product family white paper.

The system supports up to 1.6 Tbps stack bandwidth across eight switches in a single stack. It includes up to three field-replaceable power supplies, redundant fans, and front-to-back airflow to maintain availability. Security features such as Secure Boot, image signing, and runtime integrity checks validate system software and protect against unauthorized changes.

Fan units

Cisco C9350 Series Smart Switches are equipped with three field-replaceable fan modules designed with N+1 redundancy to maintain cooling even if one fan fails. The enhanced airflow design improves thermal efficiency, supporting stable operation across a wide range of deployment conditions. All fan modules are rear-accessible for easy, non-disruptive servicing.

Power supplies

Cisco C9350 Series Smart Switches support up to three hot-swappable, field-replaceable power supplies, enabling N+1 redundancy for high availability. One power supply is included by default in bay 1, with options to add a second or third for increased PoE budget or redundancy. When multiple power supplies are present, the system automatically balances the load across active units to improve efficiency and thermal performance. In PoE deployments, this allows for higher power delivery across more ports while maintaining fault tolerance.

The Cisco C9350 series power supply units (PSUs) support two modes of operation.

Combined mode

The default Cisco C9350 chassis power supply mode is Combined. In Combined mode, the total power available for the entire chassis is equal to the sum of the output of all the power supplies, multiplied by the share ratio. In Combined mode, the power supplies can be of different wattage.

• P = Power output of one PSU
• N = Number of PSU (1, 2, or 3)
• Total combined power = P + (N-1) * P * (share ratio)

Table 9 lists the different power supplies available in these switches and available PoE power.

¹ Limited by port number and port rating (e.g., 24 PoE+ 30W ports = 720W)
² Limited by port number and port rating (e.g., 48 PoE+ 30W ports = 1440W)
³ Limited by port number and port rating (e.g., 24 PoE+ 60W ports = 1440W)

Power consumption of standalone C9350 Series Smart Switches

Table 10 shows the power consumption of standalone Cisco C9350 Series Smart Switches based on Alliance for Telecommunications Industry Solutions (ATIS) testing using internet Mix (IMIX) distribution stream traffic, with input voltage of 115VAC at 60 Hz and no PoE loading. The values given are the maximum possible power consumption numbers under the respective test scenarios.

Redundant N+1 mode

The Cisco C9350 chassis also supports N+1 redundancy mode, with N independent input circuits and safeguards against the failure of one (+1) of the circuits during a PSU failure. In Redundant mode, the power supplies can be of different wattage.

• N = number of PSU are active (1 or 2)
• +1 is the PSU reserved for redundancy

Power consumption

Power consumption depends on the unique per-device hardware configuration: specifically, the supervisor engine and line cards installed and the power supplies. To model the power consumption for a specific hardware configuration, visit the Cisco Power Calculator.

Performance and scalability

The Cisco C9350 series powered by Silicon One A100/L ASIC, delivers up to 1.3 Tbps throughput, offering scalable performance and high-density connectivity. Its stackable architecture supports growing network demands with low-latency wire-speed efficiency.

¹ Multiple Security ACL types are supported. Only the first type can use the expanded scale.

SDM templates

Cisco C9350 series switches utilize predefined Software Database Manager (SDM) ASIC templates to allocate hardware resources efficiently, depending on the switch’s role in the network. These standard SDM templates are designed to optimize table sizes and performance for access and edge deployments.

The following sections describe the flexible ASIC SDM templates for the C9350 series.

Default SDM ASIC template

The Cisco C9350 series comes with a default SDM template optimized for enterprise access use cases, providing balanced resources for Layer 2 and Layer 3 forwarding, ACLs, and QoS, without requiring additional configuration.

The following table describes the default SDM ASIC (access) template for the C9350 series.

¹ IPv4 and IPv6 entries coexist in the same tables, but IPv6 entries require two entries.

² Multiple Security ACL types are supported. Only the first type can use the expanded scale.

Management

The ability to manage these devices from the cloud brings enhanced scalability, flexibility, and efficiency through central configuration management, monitoring, and troubleshooting. Users opting to leverage the cloud-native capabilities of IOS XE retain advanced control from the cloud through the implementation of Cloud CLI to access read and write commands based on their selected operating mode.

Unified experience

Cisco C9350 Series Smart Switches deliver a seamless onboarding experience to the management mode of your choice, allowing you to select the management options that best match your operational needs.

Cloud management via the Meraki dashboard

The Cisco Meraki dashboard is a cloud-native network management platform that streamlines the provisioning, configuration, and monitoring of your Cisco C9350 Series Smart Switches while reducing IT overhead. Through the guided onboarding workflow, you can choose the operating mode that fits your needs.

1. Configuration source: Cloud: Full cloud-managed provisioning and monitoring plus read-only cloud CLI terminal for advanced troubleshooting via the Meraki dashboard. For details on cloud management with cloud configuration, click here
2. Configuration source: Device¹: Configuration through console, SSH, or CLI, complemented by centralized monitoring and read/write cloud CLI terminal via the Meraki dashboard. For details on cloud management with device configuration, click here

The Cisco Meraki dashboard also supports inventory and license management for Cisco C9350 Series Smart Switches without fully onboarding them for cloud or device configuration.

Licensing

Unified licensing

Unified licensing in a Cisco Networking Subscription or an Enterprise Agreement is available for Cisco C9350 Series Smart Switches. Learn more on the Cisco Networking Subscription data sheet.

Cisco Smart Accounts

Licenses are managed on-premises through Cisco Smart Accounts. For a more detailed overview on Licensing, go to Cisco Software Licensing and Smart Accounts.

Creating Smart Accounts using the Cisco Smart Software Manager (Cisco SSM) enables you to order devices and licensing packages and manage your software licenses from a centralized website. You can set up Cisco SSM to receive daily email alerts and to be notified of expiring add-on licenses that you want to renew.

Cisco Smart Licensing is a flexible licensing model that provides you with an easier, faster, and more consistent way to purchase and manage software across the Cisco portfolio and across your organization. And secure—you control what users can access.

Cisco Enterprise Agreements

The Cisco Enterprise Agreement (EA) is a flexible licensing solution that simplifies the purchase, management, and deployment of Cisco technologies.

By combining multiple Cisco software and services into one agreement, the EA provides easy access to a wide range of products, including networking, security, collaboration, and data center solutions.

This approach reduces administrative tasks, offers predictable costs, and allows for scalability and adaptability. With the flexibility of the Cisco EA, organizations can drive digital transformation and innovation while maintaining control over their IT investments.
