Thank you for contacting RUCKUS Lennar Home Community.
Hope you are doing well!!!
Thank you for the information you shared.
As per the case description, I could understand that your RUCKUS setup is not working, and ICX 7150-C12P Switch is not getting an IP Address.
As I see from the picture you shared, seems like the ethernet cable coming from the Router or Modem/Router combo, is plugged into the wrong port on the Switch panel. It must be plugged into any 1-in-12 ports as shown in the below screenshot. Please unplug that ethernet cable and plug it into the correct port and try again.
Please refer to the short guide link below about how to connect the devices as reference:
In the picture shared the front panel where we can see the switch status LED's are not visible. Could you please share a pic from front panel of the switch where we have the system and status LED's of the switch visible ?
Also could you please let me know if you were able to run through the article shared and if you can console to the switch ?
