Patrick, thanks for the info
Joseph, very cool :)
Brian, I will research the power controller. sounds like a good idea
The replies were very encouraging, I was somewhat trigger shy about turning
the lab on. I am still waiting on some more WAN cables to be shipped but I
should be up and running by next week. I ran all 4 switches on one outlet
about a month ago for a couple hours, but this was before I really thought
about how much power was being used up...then I started to worry :)
Thanks everyone!
