Connecting the Switches to Form the Stack

After you have installed the individual switches, connect them using the stacking cables.

See Examples of Stacking Configurations for recommended ways to set up stacks and connect switch ports.

Stack ports correspond to the following physical ports on 220 series switches:

Thermal Shutdown and Restart Behavior: Exceptions

Number of Switch Ports Stack Port 1 Stack Port 2
48-port switches SFP+ port 49 SFP+ port 50
24-port switches SFP+ port 25 SFP+ port 26

In general, it is best to connect Stack Port 2 on one switch to Stack Port 1 on the switch with the next higher slot number. Although you can connect the switches in any order, connecting them as shown in these examples will produce better predictability and easier software configuration.

It is essential to create an unbroken data path through all of the switches in the stack.
