There are 2 different versions of code for the ICX switches depending on what you are doing with them. Layer 3 or Layer 2. If you are going to be doing L3, you will need a license for that.
Software on the device is listed within:
SPS – S is for Switching
SPR – R is for Routing
Ruckus Recommend if you are using L3 then to boot the system to SPR.
Once it has rebooted do not forget to make sure you set it to boot from the Router image if the switch was to reboot for any reason. (make sure you are in configure terminal mode or you will cause a reboot)
This is correct in (config) mode
