Power Over Ethernet (Poe); Connection Of Ethernet Cable; Poe Pd Usage; Insulation Strength Of Ethernet Ports - Advantech SmartFlex SR307 User Manual

The crossover UTP cable (Ethernet cable) plugs into the RJ45 connector labeled as ETH0
or ETH1 (see 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

5.8.7 Power over Ethernet (PoE)

On the router models with PoE, the PoE+ standard IEEE 802.3at-2009 and PoE standard
IEEE 802.3af-2003 are supported in both Ethernet ports (ETH0, ETH1). The PoE PD version
allows the router to be powered over the Ethernet by another PoE PSE device. The PoE PSE
version also allows the router to power other devices over the Ethernet.
