Hi [NAME],   As long as the switch stack ports located at the rear are not connected to any of the stack, it won't affect any exist network configurations. Removing the stacking configuration on the switch will also not affect your current configuration of the switch.  
I have a N3248PXE-ON switch and it seems to be stacked even though I did not configure that. Am I reading this correctly that it is the master of a stack and if so is this going to screw anything up. Looks like I could have the option of removing it from the stack but don't want to break any of my other configurations.[IMAGE]
