I have a 16 port fast switch and all 16 ports are connected with one thing or another. I need more open ports to connect to. I don't want to trash the one I have and just buy a 24 port switch (if there is such a thing). So, do I connect these things in series or is this where a bridge and another switch enter into the picture? I obviously don't want to create network interference or clutter no matter what I do. Thanks in advance.
