Connecting the Switches to Form the Stack Ring

After you have installed the individual Summit switches (see
using the stacking cables. The examples in this section show cable connections and the recommended
order for connecting ports to facilitate the easy setup configuration.
In general, it is best to connect Stack Port 2 on one switch to Stack Port 1 on the switch with the next
higher slot number. Although you can connect the switches in any order, connecting them as shown in
these examples will produce better predictability and easier software configuration. It is essential to
create an unbroken data path through all the switches in the stack.
NOTE
The connection recommendations in this section do not apply to Summit X650 series switches with
installed VIM1-SummitStack512 modules. For information about connecting the ports on the
VIM1-SummitStack512 modules, see
For instructions to connect specific types of stacking cables, see
page 151.

Using SummitStack Ports and 40G Stacking Cables

SummitStack ports are integrated into the back panel of the Summit X250e, X450, X450a, and X450e
series switches. In addition, the X460, X480, and X650 series switches accommodate VIMs or stacking
modules that provide SummitStack ports.
The examples in this section show physical stacking arrangements that include all switches in a single
rack, switches in two adjacent racks, and switches at the tops of several racks in a row.

Single-Rack Stacking Configurations

These examples show stacks of either four or eight switches in a single rack. The slot numbers presume
a console connection to the switch at the top of the physical stack.
Figure 94 shows cable connections for a 4-node stack using SummitStack 40G cables to connect switches
with integrated SummitStack ports.
