The PoE indicator consists of only two resistors, one LED and several diodes, unlike existing PoE indicators containing a PoE controller and as a result having an increased cost and low reliability and not always supporting all PoE standards.
The PoE indicator, which has original circuitry, supports all existing PoE standards, is simple and reliable. It is cheap to manufacture and easy to repeat, and easy to understand for the user. The LED is lit, which means that there is a PoE voltage supply in the network interface. Existing indicators do not support all standards and show only supported ones, they are significantly expensive and take up more space.
Controllers are not used. Passive elements are used.
