Adding another switch in my network? What isthe proper way to do so? I have: cable modem ---- smoothwall firewall ---- cisco router ---- linksys switch ----- linksys switch --- PC's when connecting 2 switches via cat5 cable, do I just plug the cable connecting the 2 in any RJ-45 hookup on both sides or does it matter? Can it be just any old regualr cat5 or 6 cable? Thanks for any info.
