Table 5: Ethernet Connector Pinout Description of RJ45 Socket
All four ETH0 ports can be used for PoE PSE if the router is equipped with this feature. For more information
about the PoE, see Chapter 2.5; for technical parameters, see Chapter 4.10.
The isolation barrier of the Ethernet ports against the ground is 1500 V.
