Thank you for contacting Lennar Home Community.
Hope you are doing well!!!
As per the case description, I could understand that your ICX-7150-C12P Switch is not getting power.
Could you please check if the Switch power cord/cable is working or check with a different power cord/cable?
Could you please plug your ICX-7150-C12P Switch into a power outlet and send us a picture of it? Please refer to the below picture as an example.
Before uploading the photos please log in to the RUCKUS account and you can upload the image.
Please let me know if you have any queries in this regard.
Thank you again.
