Adding two 2960S to an existing 2960s stack

[rsjordan00]

I need to add two additional 2960S switches to my stack. I saw a diagram that showed how a 4 switch stack can be connected, but I couldn't find much detail on adding a switch to an existing stack (besides master election). The output below shows how the existing stack is connected and its state

SW#sh switch detail

Switch/Stack Mac Address : 0011.2222.3333

                                           H/W   Current

Switch#  Role   Mac Address     Priority Version  State

----------------------------------------------------------

*2       Master 0011.2222.3333     1      1       Ready              

          Stack Port Status             Neighbors    

Switch#  Port 1     Port 2           Port 1   Port 2

--------------------------------------------------------

  1        Ok         Ok                2        2

  2        Ok         Ok                1        1

I will need to break one of the stack rings between SW1 and SW2 in order to connect the new switches. Does it really matter which ring I break to connect the additional switches? Does one ring act as primary? If so, I'd rather not break that ring so this process is transparent as possible. Also, is there any benefit to disabling the stack port vs just disconnecting the cable?

Good grab! I figured it was answered before but my search for "2960S stack" was not providing fruitful results. This article addressed my concerns.

Thanks
