NOTE: A ring topology is recommended under normal operation because it provides increased resiliency when compared
with a daisy chain topology. In daisy chain topology, any change in a non-edge stack unit causes a split stack.

Example 2: Dual Daisy-Chain Stack Across Multiple Chassis
Using two separate, daisy-chained stacks in a stacking topology provides redundancy and increased high availability in case of stack
failure. Also, stacking upgrades are simplied when you have to take one stack oine, as shown in the following examle.
