From other posts I see there is not much I can do but replace it. I doubt if it can be RMA'd as I moved in here in April 2020. I have done the following steps. Reset the AP from the web. Moved to a different POE port on switch. Reset switch. Nothing makes a difference. I don't know when this went red. But have had no power surges or outages. Last time I was checking the web page both were available.
