Are there any adverse effects of using 2 ethernet switches in series? We are running out of room to have home-runs from the main switch to each controller. For example, we would run a cable from the main switch near the show computer to a 5-port switch inside the first controller box, then a cable from the 5-port switch to the controller in that box and another cable to the other controller in a separate box. Each controller runs 400 RGB pixels, in case that is a factor.
