Good time!
I apologize in advance for my English language. By PoE, I have 2 cameras connected (on port 2 and 3). The camera remained alive after a thunderstorm. Mikrotik partially survived, namely: it turns on, all ports work, even the settings are preserved. But along the line, PoE writes overload. Found defective 2 transistors, 3 resistors. But the operational amplifier is still in question. Could he have been killed?
A little later I will upload a photo of the damage.
