Figure 16. Stack of Four Switches in the Ring Topology
The topologies are the same in terms of network speed and performance. However, the ring topology is the recommended wiring configuration because of the secondary path through the stacking ports. The two pathways protect the switches of the stack against the loss of communications due to a failure of a stacking port, cable, or switch.
The examples in the previous figures showed the twinax AT-StackXS/1.0 stacking transceiver. But the same rules apply to the fiber optic AT- StackOP/0.3 and AT-StackOP/9.0 stacking transceivers. A fiber optic transceiver in the S1 slot must crossover to a fiber optic transceiver in the S2 slot of another switch.
