Description of the device
3.3 TP ports (twisted pair)
SCALANCE X-100
22 Operating Instructions, 12/2016, A2B00060666-08
Note
Permitted cable lengths
TP cords or TP
-XP cords with a maximum length of 10 m can be connected to the TP port
-45 jack.
With the IE FC cables and IE FC RJ
-45 plugs 180, an overall cable length of a maximum of
100 m is permitted between two devices depending on the cable type.
With the autonegotiation mechanism, repeaters and end devices can automatically
determine the transmission speed and the transmission mode of the partner port. This
makes it possible to configure different devices automatically.
Two components connected to a link segment can exchange information about the data
transfer and can adapt their settings to each other. The mode with the highest possible
speed is set.
Note
Devices not supporting autonegotiation must be set permanently to 100
Mbps half duplex or
Mbps half duplex.
Note
The IE switches of the SCALANCE X
-100 product line are plug-and-
play devices that require
no settings during commissioning.
If the pair of receiving cables is connected incorrectly (RD+ and RD- interchanged), the
polarity is adapted automatically.
MDI / MDI-X autocrossover function
With the MPI/MDI-X autocrossover function, the send and receive contacts of an Ethernet
port are assigned automatically. The assignment depends on the cable with which the
communications partner is connected. This means that it does not matter whether the port is
connected using a patch cable or crossover cable. This prevents malfunctions resulting from
mismatching send and receive wires. This makes installation much easier for the user.
