I read through the Summit X670 product literature and specifications however it is not clear to me what the actual uplink / stacking link bandwidth is of the X670-48x-FB.
I am looking to deploy 5 separate "stacks' of X670-48x-FB switches which are separated by approximately 20-30m between each switch. The maximum stack size is 7 switches. I understand that ports 47 and 48 are the stacking ports, however can these ports be configured for 40Gbe or only 10Gbe on this particular model?
Is it correct that ports 45 and 46 are disabled when ports 47 and 48 are used to stack the switches together?
Lastly, are different SFPs (40Gbe?) required on ports 47 and 48 to stack the switches to leverage the maximum back plane bandwidth possible?
