As per the case description, I could understand that your wall Ethernet connections are not working when connected to the RUCKUS ICX-7150-C12P Switch, the APs are configured fine with WIFI. And you are getting a down port message on those ethernet connections.
Could you please let us know the following information?
On your switch while it's plugged into the outlet, do you see any lights on? (Amber or green) Please let us know which lights are on. (Please refer to the below picture)
Thank you for the pictures and information you shared.
Could you please let me know if you are using PoE or Non-PoE devices on those 6 non-working ports?
And please try to swap a working port cable to any one of those 6 non-working ports (As shown in the picture below) and confirm if that works to check if the issue or problem is with the cables or the ports to follow up and assist you accordingly.
Please let me know if you have any queries in this regard.
