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:
Router Version Insul. Strength from Router
Without PoE 1.5 kV
PoE PD 1.5 kV
PoE PSE none
