Data Stack Cabling Configurations

Switch Stacking and Power Stacking Guidelines

For general concepts and management procedures for switch stacks, see the switch software configuration guide on Cisco.com.

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. For switch dimensions, see Appendix A, “Technical Specifications.”

•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 the “StackWise Ports” section on page 1-18. The “Data Stack Cabling Configurations” section on page 2-5provides examples of recommended configurations.

•For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see the “Planning a StackPower Stack” section on page 2-8.

•You can create data stacks with up to four switches in a stack.

Data Stack Cabling Configurations

Figure 2-1is 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 (Figure 2-1) uses the supplied 0.5-meter StackWise cable. The example shows the full-ring configuration that provides redundant connections.
