MRP Installations
At this point, the NX2A4E2 is configured and ready to use. If you are using the unit in a redundant, ring
based, network that uses the Media Redundancy Protocol (MRP), continue with the following instructions.
6.7 Configure the NX2A4E2 as an MRC
The NX2A4E2 functions as a Media Redundancy Client (MRC) in an MRP network.
1) Switch to Topology view and drag the additional connections between the appropriate ports.
2) Click on the NX2A4E2 icon to select it. In the Inspector window, select Advanced o> Media
redundancy . Use the “MRP domain:” drop down menu to select the appropriate domain. Use the “Media
redundancy role:” drop down menu to select “Client”.
3) Continuing in the Inspector window, select Advanced o> Port 1 +> Port interconnection . Under
“Partner port:”, the partner port you assigned to the port when you drew the topology is shown. If you do
not know which port will be the partner port in the actual installation, you can use the drop down menu to
select “Any partner”.
4) If need be, repeat step 3 for Port 2 of the NX2A4E2.

5) Continue configuring the rest of the devices on the network before compiling the project and downloading
it to the CPU.
Media Redundancy Protocol (MRP) installations require that the NX2A4E2 be
installed in a ring topology. In these applications, both Ethernet ports are used
when wiring the ring, daisy chaining from one unit in the ring to the next. The
steps below covers typical software configuration that must also be completed.
