The platform also supports up to 1.6 Tbps stack bandwidth available across eight switches when stacked together and features three field-replaceable power supplies for enhanced power resiliency, redundant fans, and front-to-back airflow. Built-in security features like secure boot, image signing, and runtime integrity ensure a robust and secure foundation for modern enterprise networks.

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) supports 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 6 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)

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 active PSUs (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.
