The solution I found was:
Using ethernet port 1 of each pair with a crossover
Pair 1: 192.168.0.x set to broadcast on range 192.x.x.x
Pair 2 10.0.0.x set to broadcast on range 10.x.x.x
Using ethernet port 2 to a hub
All servers in ranger 2.0.x.x
Set all servers to accept remote presets
set 1A and 3B to broadcast sync
set C to send preset sync commnands

It allows primary and backup to have independent sync pulse while accepting commands from the main controller across all servers.
