Stacking Slots
The S1 and S2 slots on the front panel of the switch are used with the
VCStack feature and the stacking transceiver to create a stack of up to
four switches. The switches of a stack act as a single virtual unit. They
synchronize their actions so that switching operations, like spanning tree
protocols, virtual LANs, and static port trunks, span across all the units and
ports. The two main advantages of stacks are:
 You can manage multiple units simultaneously, which can simplify
network management.
 You have more flexibility with 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.
The stacking transceiver is shown in Figure 7. It is called the AT-StackXS/
1.0 transceiver. It has two SFP transceiver-style connectors and one
meter of twinax cable.

Note
The stacking slots only support the stacking transceiver. They
cannot be used as regular networking ports.
