Examples of Valid Stacking Congurations
The examples in the following sections show various physical stacking arrangements:
all switches in a single rack, switches in two adjacent racks, and switches at the tops of
several racks in a row.
Example: Basic Stack with Four Switches
This example shows a stack of four switches in a single rack.
The slot numbers presume a console connection to the switch at the top of the physical
stack.
Figure 29 shows cable connections for a 4-node stack using SummitStack 40G cables
to connect switches with integrated SummitStack ports.
