6.5 Industrial Ethernet
Autonegotiation
Autonegotiation means the automatic detection/negotiation of the transmission rate and the
operating mode of ports at the opposite end. This makes it possible to configure different devices
automatically.
Two components connected to a link segment can exchange information about the transfer
and can adapt their settings to each other. The mode with the highest possible speed is set.
Note
• If a port is set permanently to full duplex, the connected partner port must also be set to full
duplex.
• If a port operating in "Autonegotiation" mode is connected to a partner port that is not
operating in "Autonegotiation" mode, the partner port must be set permanently to 100 Mbps
or 10 Mbps full-duplex mode.
• If you disable the "Auto negotiation" function, the "MDI/MDI-X autocrossover" function is also
turned off. Then use a crossover cable.

NOTICE
Failure of the data traffic due to contamination of optical plug-in connections
Optical sockets and plugs are sensitive to contamination of the end face. Contamination can
lead to the failure of the optical transmission network. Take the following precautions to avoid
functional impairments:
• Clean the end face of field-assembled connectors carefully before connecting. No residues
• Only remove the dust caps of optical transceivers and pre-configured cables shortly before
• Close unused optical sockets and plugs as well as pluggable transceivers and slots with the
LC connector technology
The attachment to Industrial Ethernet uses LC connector
technology (Lucent Connector).
