Cisco Part Number: PWR-C2-850WAC-I= is a Cisco 850W AC 80+ platinum Port-Inlet Power Supply, spare
The Cisco C9350 Series Smart Switches are designed with flexible power redundancy and scalability in mind. They support up to three hot-swappable, field-replaceable power supplies, ensuring N+1 redundancy for continuous operation and high availability.
Default configuration: Each switch ships with a single power supply installed in Bay 1.
Expansion options: Additional second and third power supplies can be added to increase either the Power over Ethernet (PoE) budget or overall system resilience.
Smart load balancing: When multiple supplies are installed, the switch automatically distributes power demand across active units, enhancing both efficiency and thermal performance.
Optimized for PoE: This design enables higher total power delivery across more ports, while still maintaining fault tolerance for critical deployments.
In summary, the C9350’s modular power architecture provides a reliable foundation for demanding enterprise networks, combining scalability, efficiency, and resilience in PoE-driven environments.
