Can the following C3750 switches be mixed stacked (Stackwise)?

[FirasChahine]

Hello everyone,

I currently have these two C3750 switches stacked:

Switch Ports Model              SW Version            SW Image                 

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

     1 52    WS-C3750G-48TS     15.0(2)SE11           C3750-IPSERVICESK9-M     

*    2 52    WS-C3750G-48TS     15.0(2)SE11           C3750-IPSERVICESK9-M     

Is it possible to add the switch below to the group?

Switch Ports Model                     SW Version            SW Image                 

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

*    3 54    WS-C3750X-48P             15.2(4)E10            C3750E-UNIVERSALK9-M     

C3750X#show license

Index 1 Feature: ipservices     

        Period left: 8  weeks 4  days 

        License Type: Evaluation

        License State: Active, Not in Use, EULA not accepted

        License Priority: None

        License Count: Non-Counted

Index 2 Feature: ipbase         

        Period left: Life time

        License Type: Permanent

        License State: Active, In Use

        License Priority: Medium

        License Count: Non-Counted

Index 3 Feature: lanbase        

        Period left: 0  minute  0  second

If so, is there something I need to do aside from simply connecting up the stackwise ports?

Thank you in advance!

@Leo Laohoo  @balaji.bandi  you were right, it did not work after all. I had to downgrade in order for the 3750X to function. Although it was initially part of the stack, none of its ports came up. Lesson learned

That's the basic rule of the stack all should be the same version, if not how will the command syntax matches? 

Glad all work as expecting.
