To link two switches you may need a crossed ethernet cable[1] OR 
if your switch has an "uplink" port (sometimes with a button to 
tell the switch that you've cascaded a switch), then you can use 
a straight ethernet cable into that port (and press the button 
if need be). Usually it's the last port on the switch.
