Data Stack Cabling Configurations

Switch Data Stacking Guidelines

For general concepts and management procedures for switch stacks, see the switch software configuration guide on Cisco.com. When adding a Catalyst 3750-X switch to a Catalyst 3750 switch stack, review the Catalyst 3750-X Switch Stack Compatibility Guide on Cisco.com for information about mixed stack configurations.

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 1-16. The “Data Stack Cabling Configurations” section on page 2-5provides examples of recommended configurations.

•For rack-mounted switch stacks connected to the XPS-2200, review this recommended sequence of events:

–If you are using the XPS-2200, install the XPS first at the bottom of the stack. If needed, allow one RU space between the XPS and the first switch above to provide room for cabling.

–Connect the 12-pin XPS cables to the XPS-2200.

–Rack-mount the switches. If you have the optional 1100-W power-supply module, first mount the switch before installing the power-supply module.

–Connect the XPS cable to the first switch above the XPS-2200. Connect the stack cables to the first switch above the XPS.

–Connect the XPS cable to the second switch above the XPS-2200. Connect the stack cables to the next switch above the XPS.

–Repeat until all switches are connected.

•For rack-mounted switch stacks that are members of a StackPower stack as well as a data stack, see the “Planning a StackPower Stack (Catalyst 3750-X Switches)” section on page 2-8.

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.
