Figure 3-3 shows an example of a stack of Catalyst 3750 switches with
incomplete StackWise cabling connections. This stack provides only half
bandwidth and does not have redundant connections.
Figure 3-3 Example of a Stack with Half Bandwidth Connections
Figure 3-4 and Figure 3-5 show examples of stacks of Catalyst 3750 switches
with failover conditions. In Figure 3-4, the StackWise cable is bad in link B;
therefore, this stack provides only half bandwidth and does not have redundant
connections. In Figure 3-5, link B is bad; therefore, this stack partitions into two
stacks, and switch 1 and switch 3 are stack masters.
