Usually the way to initial set up the stack is as follows (quick and simple) 
 
-  set up the stack devices, but do NOT connect the stacking cables 
-  turn on all devices and connect to the first on by Console  
-  connect to them via console program like PUTTY (COMx, 115200 baud , 8N1)  
o  enter command “config stacking_mode enable” and confirm with “y” 
“ 
DGS-3420-28SC:admin#config stacking_mode enable 
Command: config stacking_mode enable 
 
Change Box bootmode may cause devices work restart, still continue?(y/n)  y 
Please wait, the switch is rebooting... 
“ 
-  repeat this step for ALL devices in your setup to enable the stacking 
 
-  after enabling stacking on all devices we recommend to manually define BoxID and Priority for Master 
and Backup-Master  
o  config box_id current_box_id 1 new_box_id 1 
o  config box_priority current_box_id 1 priority 5 
o  save the settings with  “save” 
o  then reboot the switch again with “reboot”  
 
-  repeat this for all the Switches, but increase the “Priority” Value in 5 numbers (f.e. 
5,10,15,20,25,30,35,40,45,50,55,60) and the “new_box_id” from 1-12 (depending of the maximum 
number of devices which can be stacked together) 
 
-  now you can connect the stacking cable on the last 2 10G Ports , which by now are pure stacking ports 
 
 
-  then connect the console to the device with the “H” and run following command 
o  “show stack_information”, to  see then all the stacked devices 
“ 
DGS-3420-28SC:admin#show stack_information 
Command: show stack_information
