Default settings: autonegotiation.
The socket housing is electrically connected to the front panel.
The pin assignment corresponds to MDI-X.

Note: In general, you should adhere to the following recommendations for
data cable connections using copper in environments with high electrical
interference levels:
 Keep the length of the data cables as short as possible - ideally max.
3m long. You should not use any copper data cables for the data
transmission between buildings.
 Power supply and data cables should not run parallel over longer
distances, and ideally they should be installed in separate cable
channels. If the inductive coupling has to be reduced, the power
supply and data cables should cross at a 90° angle.

You may also choose to use shielded cables. Ground the cable
shielding at one point in order to avoid causing a ground loop.

10/100 Mbit/s twisted pair connection PoE
10/100 Mbit/s ports (RJ45 or M12 sockets) enable the connection of
terminal devices or independent network segments according to the IEEE
802.3 100BASE-TX / 10BASE-T and IEEE 802.3af (Power over Ethernet
on data lines) standards. These ports support:

Autonegotiation
 Autopolarity

Autocrossing (if autonegotiation is activated)
 100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
 10 Mbit/s half-duplex mode, 10 Mbit/s full duplex mode

Power over Ethernet (PoE)
Delivery state: autonegotiation activated
The socket housing is electrically connected to the front panel.
The PoE voltage is supplied via the wire pairs transmitting the signal
(phantom voltage).
