CCO will give you their specs, for example:
http://www.cisco.com/univercd/cc/td/doc/product/access/acs_fix/cis2500/2501/
2500ug/ovr.htm
however, i'm a real world man in respect to what do these puppies really
draw. Though CCO shows 1.2 A for 2500's my actual measurements were like
.5A. The best way to know for sure, especially that 5000 is gona take a lot
of amps is to measure it. Go to Radio shack, plop down $15.00 for a DVM
that measures current up to 15-20 A or so (Actually the one i got was a
cheap analog one). The meter you want has a C -shaped looking clamp on the
outside just to measure AC current. You will need to plug your routers into
a cheap 2 wire extension cord that you will split the two wires away from
one another by cutting down the center of the extension cord (leaving
insulation on of course) to separate the two wires away from each other.
You then wrap one of the wires through the C clamp of the DVM and measure.
Practice first on a 120 Watt lamp. It should measure about 1amp.

Subject: Proper supply of power to equipment
I'm basically looking for advice on how many routers and switches I can plug
into a 20 amp circuit breaker. I don't want to over load anything with my
home lab. I've got 1 cat 5000, two 7000's and 7 2500's with MAU's etc... Any
advice on how to split this stuff up? Has anyone ran across any guide lines
concerning proper power supply?
I figured I would try to split this stuff across two separate 20 amp
breakers. Any suggestions?
Thanks in advance!
Bryan
