Hi, You would have to daisy chain between stacking modules on all four switches. Stacking between floors is probably not going to work properly as the max cable distance is 3m. [URL] page 2
How would you stack a total of 4 7048 switches with 2 switches on each floor?  Both groups of 2 switches are located 1 floor apart from each other.  What additional modules and cables are required?  thanks.
Possible to stack 4 7048 Switches 2 on each floor
