Planning a Switch Data Stack

Cisco Catalyst 9300 switches can share bandwidth by using data stacking.

Switch Stacking and Power Stacking Guidelines

Before connecting the switches in a stack, keep in mind these stacking guidelines:
• Size of the switch and any optional power-supply module. The 1100-W power-supply module is longer
• Length of cable. Depending on the configurations that you have, you might need different-sized cables.
• For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see
• You can create data stacks with up to eight switches in a stack.

Data Stack Cabling Configurations

This is an example of a recommended configuration that uses the supplied 0.5-meter StackWise cable. In this
example, the switches are stacked in a vertical rack or on a table. This configuration provides redundant
connections. The configuration example uses the supplied 0.5-meter StackWise cable. The example shows
the full-ring configuration that provides redundant connections.

than the other modules. Stacking switches with the same power-supply modules together makes it easier
to cable the switches.
If you do not specify the length of the StackWise cable, the 0.5-meter cable is supplied. If you need the
1-meter cable or the 3-meter cable, you can order it from your Cisco supplier. For cable part numbers,
see StackWise Ports, on page
of recommended configurations.
