Stacking Transceivers
You connect the switches of the VCStack with the stacking transceivers
listed in Table 5 and shown in Figure 12.
Figure 12. Stacking Transceivers
With its two SFP+ transceiver-style connectors and one meter of twinax
cable, the AT-StackXS/1.0 transceiver is appropriate in situations where
the switches are in the same equipment rack or on the same table.
The fiber optic transceivers are used to build stacks across large
distances.
