I basically have the exact same setup that you have..... including some
additional 25XX routers. It sounds like you had the same idea I had -buy all
of the equipment for the IPexpert labs for your home lab. I live in an
apartment too so I understand the power concerns. What I can tell you is,
(as crazy as it sounds), I run all of the equipment at the same time off of
two 110V outlets in my living room. (With the help of 3 power strips.) To
work the practice labs I have to run 18 devices at once (11 routers, 4
switches, 2 terminal servers and a 2522 for the FR switch.) I've done this
using those 2 110V outlets and have had no problems. To be honest I'm
shocked that I haven't blown a breaker yet.
Hope this helps...
On a side note... being new to the group... I'm not sure if I'm replying
correctly. I'm taking the email I receive and selecting "reply to all". It
then sends an email to the person who posted the question/reply and also to
ccielab@groupstudy.com. Am I doing this correctly?
Thanks,
Mod.
