Does anyone know what are the step by steps to solve?

Thanks in advance.

I have no idea what is wrong here. 

I can see one switch and switch #2 is "provisioned" state.  

[danielesquaranti]

The stack cables are attached.

The switch 2 have a blank config and is renumbered as two.

The switch 1 have:

switch priority 15

switch 2 provision ws-c2960x-48ts-l

-----------------------------

I reboot the two switches and the result is this...

[Leo Laohoo]

Console into the 2nd switch and reboot. 

Post the entire boot-up process.

One more thing:  Remove the IP addresses and names.  Do not remove or edit out anything else because there are useful information we need to see.

Sorry for the long delay,

Finally i find the error: the port-speed of the two switches did not match. 

So i change this property and the stack comes up.

Anyway, there were no reference of "speed mismatch" in the console logs...

Thanks for the support.

Hello @danielesquaranti ,

>> Finally i find the error: the port-speed of the two switches did not match. 

What port speed are you referring to ?

Are you using stack cables to build the stack , aren't you ?

Hope to help

Giuseppe

[danielesquaranti]

Sorry,

I mean the stack-ring speed.
