NOTE
According to IEEE 802.3af/at standards, the PD shall be
implemented to be insensitive to the polarity of the power supply
and shall be able to operate per MDI mode and MDI-X mode.
However, some PDs only support MDI mode or MDI-X mode only.
The following figure shows how to select the correct cable
between the PD and EDS-G205A-4POE.
