3. Ifyouareinstallingthisswitchinastackedconfiguration,repeatthisprocedurefor
eachswitchuntilallswitcheshavebeeninstalledinthestack,thenproceedto

“ConnectingACandPoEPower”onpage 3‐14.
Connecting High-Speed Stacking Cables
Thestackofswitchescanbeconnectedinaringordaisychaintopology.Inaring
topologyalltheswitchesareconnected.Theonlydifferenceinthecableconnectionsina
daisychaintopologyisthatonecableisnotinstalled.
Upto8switchescanbestackedtogetherusing
C2CAB‐SHORTandC2CAB‐LONG
high‐speedstackingcables.Youcanaddswitchesandreachuptoamaximumof384
Ethernetportsperstack.Thehigh‐speedstackingcablesallowtheentirestacktooperate
withasingleIPaddress.
