I purchased a bunch of miscellaneous wifi hardware to use to help out individuals that have been forced to work and school at home.  The initiative worked well.   After everything was done I had a few left over pieces that never worked.   The one that interested me the most was the eap225-outdoor.

When it was connected it would smell like burning.  So I opened it up and applied power.   I found the small surface mount component labeled T9 was glowing red hot

I dabble in electronics repair and would like to add this to my omada setup at home.

Does anyone know what this component is?  Also does anyone want to guess if its just this part that failed or if there is another part that caused it to fail.   It's right off of the ethernet port, so I assume it has to do with PoE
