The unit has a blown capacitor, bulged and brown matter around it. Also there is
a white-ish powder under the PCB. It looks dirty. There is corrosion.
Not sure it's
worth fixing. It went on for well over a year working perfectly in a
well ventilated
room. The unit is for a server at my workplace, so they will replace it.
Many years ago, I used to make and fix network cards and switches at some
company, so I'll give it a shot myself at fixing this one just for kicks.

I very much appreciate your offer to fix this thing --even though there was no
warranty implied. :-)

Now, I've got to get a more reliable unit to last longer.
