In my office I'm running a single 24 port ethernet switch. I'll probably need to upgrade to 48 available ports in the the near future. Suggestions? Just buy another 24 and run them side by side? save up the budget for a more expensive single 48 port switch? What do I lose in speed/security by using more than one switch? Any tips or tricks on how to get this going with the least amount of glitches? Thanks!
