5.9.6 Ethernet Ports (ETH0 and ETH1)

The panel socket RJ45 is used for this interface. The isolation barrier of the Ethernet signal
ports against the ground is 1500 V.
The crossover UTP cable (Ethernet cable) plugs into the RJ45 connector labeled as ETH0
or ETH1 (see the figure below).
The insulation strength of Ethernet ports from each other and from the rest of the router
(grounding) is dependent on the router version:
