Topology
The MCA121 features a build-in Ethernet-switch, thus having two Ethernet RJ-45 connectors.
This enables the possibility for connecting several EtherNet/IP options in a line topology as an
alternative to the typical star-topology.
The two ports are equal, in the sense that they are transparent for the option. If only one connector is
used, either port can be used.

Note: For line topology please refer to section: “Recommended design rules”
In a line topology all drives must be powered, either by mains or 24 V DC option, for the build-
in switch to work.
