When using the MFR-31CPU, each of the two MFR-LANs should be connected to their respective
devices to enable CPU redundancy. Also, when connecting MFR series devices to LAN, they
should be on a separate network from other systems, such as an internal LAN. Do not use the
spanning tree or other functions that inhibit or restrict communication in MFR-LAN.
