Figure 223: SummitStack Configuration Using Dierent Switch Models and
SummitStack 40G Cables
Example: Stacked X650 Switches with VIM1-SummitStack Modules
Figure 224 shows an example of a four-switch stack that includes two Summit X650 series switches. In
the Summit X650 series switches. the SummitStack ports are on installed VIM1-SummitStack modules.
The Summit X650 series switches are placed at the top of the stack and will be designated the stack
master and backup nodes. The recommended order for connecting the stacking ports is the same as for
the example in Example: Basic Stack with Eight Switches on page 296.

Figure 224: SummitStack Configuration Using SummitStack X650 Series Switches and
SummitStack 40G Cables
Example: Stacked Switches across Two Racks
The following example shows four switches – two of one model, two of another model – physically
located in two adjacent racks.
In each rack, an X480 series switch is placed at the top, with an X650 series switch below it. The
switches are connected into a stack using SummitStack ports on installed VIM2-SummitStack and VIM1-
SummitStack modules. In this example, start by connecting the X480 switches together; they will be
designated the stack master and backup nodes (slot 1 and slot 2, respectively).
