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
than the other modules. Stacking switches with the same power-supply modules together makes it easier
to cable the switches.
• Length of cable. Depending on the configurations that you have, you might need different-sized cables.
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 Accessories, on page 115
. The
Data Stack Cabling Configurations, on page 30
provides
examples of recommended configurations.
• For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see
Planning a StackPower Stack, on page 33
• 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.
Figure 12: Data Stacking the Switches in a Rack or on a Table Using the 0.5-meter StackWise Cables
This example shows a recommended configuration when the switches are mounted side-by-side. Use the
1-meter and the 3-meter StackWise cables to connect the switches. This configuration provides redundant
connections.
