Imagine being able to combine multiple physical switches into a single, logical unit. That’s StackWise Plus. This technology allows you to create a stack of up to 9 switches, managed as one, with a resilient backplane of 64 Gbps. This simplifies management, improves redundancy, and allows for easy scalability as your business grows.
Enhanced Reliability & Power:
The switch supports redundant power supplies with the optional RPS 2300 (Redundant Power System), ensuring critical operations continue even if one power supply fails. It also supports Cisco Universal Power Over Ethernet (UPOE)* on other models in the series, demonstrating the platform's robust power design.
