Permitted cable lengths
TP cords or TP-XP cords with a maximum length of 10 m can be connected to the TP port with
RJ-45 jacks.
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.
Autonegotiation
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.
