I have just set up a network that involves two 3G routers driving effectively two independent networks but on the same site. I would like the ability to swap over the two feeds (for balancing data usage - both 3G modems have a FUP, this is in Africa BTW). I could do it very simply with an RJ45 patch panel but I would prefer to be able to do it remotely from back here in the UK. I have zero experience of using managed switches but I'm guessing they could do the job for me. Is this correct ?
