Hello, Luis. 

insharie is correct, you basically need to have the same IOS package in order to stack. Are these for your existing 3750-X switches, by the way? 

Let me know if you have additional concerns or e-mail (adawa@cisco.com) me directly. Kind regards.

If same IOS version, my understanding is you can mix IPBase and IPServices within a stack of 3750Xs.  (LanBase won't stack with other than LanBase, I believe.)

To obtain the benefit of the IPServices, that stack member will need to be the stack master.
