Data Stack Cabling Configurations

Figure 2-3shows 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.

Data Stack Bandwidth and Partitioning Examples

This section provides examples of data stack bandwidth and possible data stack partitioning.

Figure 2-4shows a data stack of Catalyst 3750-X switches that provides full bandwidth and redundant StackWise cable connections.

Figure 2-5shows an example of a stack of Catalyst 3750-X switches with incomplete StackWise cabling connections. This stack provides only half bandwidth and does not have redundant connections.

Figure 2-6and Figure 2-7show data stacks of Catalyst 3750-X switches with failover conditions. In Figure 2-6, the StackWise cable is bad in link 2. Therefore, this stack provides only half bandwidth and does not have redundant connections. In Figure 2-7, link 2 is bad. Therefore, this stack partitions into two stacks, and the top and bottom switches become stack masters.
