Hi Jeremy,

 

(I am considering that you have configured the fail-over via serial as well as the network)

 

I will not prefer the connectivity as shown in diagram-2 you have to keep it distributed between switches 1 and 2 as shown in Diagram-1. let us say that the switch on which the Active unit is connected Fails what will happen in this situation, your Fail-over unit will not switch to the Active mode as it will continue getting the signal from the serial cable. Also failing of the switch should not cause the units to fail-over. So what will happen in this case is that all of your traffic processing will be stuck unless you do something manually. You should strictly follow what you have shown in diagram1.
