Stack Cabling Configurations

This section describes the recommended cabling configurations for stacking the switches.

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 examples in Figure 2-2use the 3-meter StackWise cable in addition to the supplied 0.5-meter StackWise cable. This configuration also provides redundant connections.
