Stacking the S3900 Series Switches
The S3900 series switches support stacking up to 6 switches between the same models together.
Switches in the series can be physically stacked using optical fiber cables connected to SFP+ transceivers,
or 10G Direct Attach Cables (DAC). Only the last two SFP+ ports on the switch can be used for physical
stacking.
