S1 and S2 Stacking Ports
The switch may be used as a stand-alone unit or as part of a stack in
which multiple units are interconnected via the S1 and S2 stacking ports
on the front panels. Compared to stand-alone switches, which function as
independent units, the switches of a stack synchronize their actions to
form a single, logical unit so that the switching operations, like spanning
tree protocols, virtual LANs, and static port trunks, are able to span across
all the units.

The two principal advantages of stacks are:
You can manage multiple units simultaneously, thus simplifying
network management.
network management.
You have more flexibility in how you configure some of the
features. For instance, a static port trunk on a stand-alone switch
has to consist of ports from the same switch. In contrast, a static
trunk on a stack may consist of ports from different switches in the
same stack.
