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 Access Point suddenly stopped working with a red light on it.
May I know how many Access Points you have connected to your ICX-7150-C12P Switch and how many Access Points there is a red light?
If it is only one Access Point, could you please unplug and plug the ethernet cable of that Access Point from the Switch port panel and check the light status again?
Please let me know if you have any queries in this regard.
Thank you again for your patience.
