Switch Stacking and Power Stacking Guidelines
Mixed stacking between C9300X and C9300 switches are supported at StackWise-480 speed. However, you
cannot stack fixed uplink switches with modular uplink switches or other Cisco Catalyst switches.
Switch Stacking and Power Stacking Guidelines
Before connecting the switches in a stack, ensure that you read these stacking guidelines:
• Size of the switch and any optional power supply module. The 1100 W/1900 W power supply module
• 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
• Up to four switches can be configured in a StackPower stack using the StackPower connector at the rear
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 18: 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.

is longer 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,

stack. Currently, C9300X switches do not support XPS-2200.
