Web interface method 
Find the firmware versions the stack members are using. 
Select System > File Management > Active Images. 
Look in the Current-Active column to find which images are enabled.  In this example all three switches 
are currently using image2.  
  Note: It is acceptable if some units are using image1 and others are using image2.   
Since image2 is active, look in the Image 2 Version column to see what version each stack member is 
at.  These firmware versions being used should be the same across all stack member units.
