Gigabit Ethernet pinouts
Figure 23: The Gigabit Ethernet ports use an RJ45 connector
The PoE zNID 27xx models are considered a “PSE Endspan” devices,
integrating data and power on the same wires following the IEEE 802.3af (at)
'Alternative A' pinout, which is the industry standard for “active” PoE.
Note that other than the PoE power variation, the pinouts for PoE and
non-PoE Ethernet ports is the same.
