3750-X not recognizes in 3750G STACK

[Lorenzo469]

Hello Guys,

I just tried to add a 3750x to 3750G stack but unfortunately the 3750X is not recognized by the Stack.

I don't understand why the 3750X is not recognized by the 3750G Stack, do you have any ideas what could be the problem ? 

The aim is ton obtain a Stack like this 3x 3750G + 1x 3750X.

Log on the 3750 G Stack

If I'm reading the license information correctly, you've only have a LANBase license, which, I believe, will only stack with other LANBase stack members.  I.e. you may need to upgrade your 3750X to IPBase.

I think this should work only if the all switches members are running the same version of IOS (12.2(55)SE9 for instance) with the following difference meanwhile 3750X in "UNIVERSALK9" and 3750G in "IPSERVICESK9".
