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 and 10/100/1000 Mbit/s twisted pair
connection PoE
10/100 Mbit/s and 10/100/1000 Mbit/s ports (RJ45 sockets) enable the
connection of terminal devices or independent network segments according to
the IEEE802.3 1000BASE-TX / 100BASE-TX / 10BASE-T and IEEE
802.3af/at/bt (Power over Ethernet on data lines) standards. These ports
support:
Autonegotiation
Autopolarity
Autocrossing (if autonegotiation is activated)
1000 Mbit/s half-duplex mode,1000 Mbit/s full duplex mode
100 Mbit/s half-duplex mode, 100 Mbit/s full duplex mode
10 Mbit/s half-duplex mode, 10 Mbit/s full duplex mode
