Figure 14. 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.
