The following cables are used to make the stacking connections:

• SummitStack 128G cable between the two Summit X650 series switches at the top (slot 1 and slot 2)

• SummitStack 128G/20G stacking cable between the Summit X650 series switch and the Summit

X460 series switch (between slot 2 and slot 3)

• SummitStack 20G stacking cable between the two Summit X460 series switches (between slot 3

and slot 4)

• SummitStack 20G stacking cable between the Summit X460 series switch and the Summit X450a

series switch (between slot 4 and slot 5)

• SummitStack 128G/20G stacking cable between the Summit X450a series switch and the Summit
