On SCALANCE X101-1, the twisted pair port is implemented as RJ-45 jack with MDI-X
assignment (Medium Dependent Interface–Autocrossover) of a network component.
Notice
TP cords or TP-XP cords with a maximum length of 10 m can be connected to the RJ-45 TP
port.
Depending on the cable type, a total cable length of up to 100 m is permitted between two
devices with the IE FC cables and IE FC RJ-45 plug 180.
Autonegotiation
Autonegotiation means the automatic detection of the functionality of the port at the opposite
end. Using autonegotiation, repeaters or DTEs can detect the functionality available at the
port of a partner device allowing automatic configuration of different types of device. With
autonegotiation, two components connected to a link segment can exchange parameters
and set themselves to match the supported communication functionality.
