Yes, you can stack the 6 switches together, any 5500 will stack with any other, to a max of 8
Can I combine a stack of four PowerConnect 5548 switches with a stack of two PowerConnect 5524 switches? I'm sure we need to ensure they're running the same firmware, but I didn't see documentation on maximum stack size or inter-model stacking limitations. Thank you.
Stacking question: can I combine a 5548 stack with a 5524 stack?
