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

* PoE capacity is limited by the number of PoE ports and their supported per-port power ratings, even when the installed PSU can provide more power. For example, 24 × 30 W = 720 W and 48 × 30 W = 1,440 W.

Power consumption of standalone C9350 Series Smart Switches

Table 8 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.

Cisco StackWise-1.6T

The Cisco C9350 Series features StackWise-1.6T, a high-performance standards-based Ethernet stacking architecture that delivers up to 1.6 Tbps of aggregate stacking bandwidth—the highest in the industry for enterprise access switching. This architecture supports stacking of up to eight switches using dedicated rear panel connectors and high-speed stack cables, forming a single, unified system with distributed forwarding and a common control plane. StackWise-1.6T enables low-latency communication, hitless failover, and simplified management, providing exceptional scalability and resiliency. Its Ethernet-based design offers improved flexibility, allowing the stack to operate efficiently in demanding, high-density environments while maintaining operational simplicity.

Cisco StackPower+

Cisco C9350 Series Smart Switches support StackPower+, an enhanced 55V power-sharing architecture that allows all power supplies across the stack to operate as a unified power pool. This enables redundant power capabilities with zero additional rack footprint, improving space and operational efficiency. With StackPower+, power from all connected supplies is intelligently consolidated and redistributed based on real-time demand, ensuring optimized delivery across the stack. By adding just one additional power supply to any member, you can increase available capacity or provide redundancy to other switches in the domain. StackPower+ also supports full 90W PoE on all ports, leveraging shared power through the stack. Up to four switches can be connected in a StackPower+ ring, delivering flexible, scalable, and resilient power management for demanding PoE deployments.

Note: Cisco C9350 Series Smart Switches are designed to work exclusively with the StackWise-1.6T and StackPower cables listed in Table 10. These switches are not compatible with stacking or StackPower cables from the Catalyst 9300 Series or other previous generation switches.
