Example: Stacked Switches across Several Racks
shows five switches installed at the tops of five adjacent racks. To accommodate the shortest
possible cables, immediately adjacent switches are not always connected together. Port 2 on one switch
is connected to Port 1 on the next connected switch. If the easy setup feature is used to configure the
stack parameters, the assigned slot numbers will be as shown in the figure.

Connecting Stacking Cables
To connect switches in a SummitStack configuration, use the appropriate stacking cables for the
specific stacking ports on the switches.
Connecting a SummitStack Cable to a Stacking Port
SummitStack cables are used to connect 20-Gbps SummitStack ports on the X460-G2 switch with the
SummitStack plug-in module.
To connect a SummitStack cable, follow these steps:
1. Align the cable connector with the stacking port connector on the rear of the first switch (see
).
2. Firmly press the cable connector into place on the mating stacking port connector.
