The article is devoted to the issues of Power over Ethernet technology – the development of injectors, their compatibility with other equipment, and operational problems. Over the years, periodically there were problems that the author had to solve and questions that required an answer. Some of them are briefly described in these notes, in the title of which the word "injectors" is placed in parentheses, since everything described applies, to a large extent, to PoE technology in general.
