Hello Geek,
Have a good time. The SNS2248 switch activates 24 ports by default. When it exceeds 24 ports, you need to apply for an activation license. When it exceeds 48 ports, you need to add a fiber switch in pairs. Cascade with the original switch trunking and need to apply for a trunking license. The cascading bandwidth is the service bandwidth between the server and the storage device.
Please feel free to ask us any questions! Thanks.
