Stacking Port Topologies
The switches of a stack are connected with the S1 and S2 ports and AT-
StackXS/1.0 transceivers, shown in Figure 15 on page 49.
There are two wiring configurations. The first topology is called the linear
topology. In this topology the switches are connected with a single
pathway. The connections must crossover to different stacking slots on
the switches. Slot S1 on one switch must be connected to slot S2 on the
next switch.
Figure 16 is an example of a stack of two switches in the linear topology.
The AT-StackXS/1.0 stacking transceiver connects the S1 slot on the top
switch to the S2 slot on the bottom switch.
Figure 16. Stack of Two Switches in the Linear Topology
Caution
The stack will not function if the connections to the S1 and S2 slots
do not crossover on the switches. The switches will not form a stack
and instead operate as stand-alone devices.
The stack in Figure 17 on page 51 has four switches in the linear topology.
