Notice
TP cords or TP-XP cords with a maximum length of 10 m can be connected to the RJ-45 TP
port.
With the IE FC cables and IE FC RJ-45 plug 180, an overall cable length of a maximum of
100 m is permitted between two devices depending on the cable type.
Autonegotiation
Autonegotiation means the automatic detection of the functionality of the port at the opposite
end. Using autonegotiation, repeaters or end devices 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.
