Example: Stack with VIM1-SummitStack Modules
Figure 43 shows an example of a four-switch stack that combines two dierent switch models: two of
each model; four switches in all. For the first switch model, the stacking ports are on installed VIM1-
SummitStack modules. For the second switch model, the stacking ports are on installed SummitStack
stacking modules. The recommended order for connecting the stacking ports is the same as for the
example in Example: Basic Stack with Eight Switches on page 68.
