The redundancy mode supports automatic switching the power and 10 MHz signals between routers. This
functionality requires that used IF splitters and combiners:
Have at least two ports;
Pass DC;
Pass 10 MHz reference signal.
This does not apply to RF equipment with other DC and 10 MHz reference signal sources.
