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.
