Additionally it can indicate a device without PoE support connected on the other side of the cable. In this case
the indication is caused by low impedance (lower than 500
Ω
) of the device without PoE support. This can be
solved by disabling the PoE PSE feature on the relevant ETH port in the router’s Web interface, see
