Great advice. BUT -- when doing this, make sure that all UPS units are 
powered off, both because they are noise sources themselves, and because 
they keep some equipment running that's also likely to be a noise source.

Lots more detailed advice in http://k9yc.com/KillingReceiveNoise.pdf

Another important delineation of noise type is between 1) electronic 
noise, generated by electronic equipment, solar power systems, variable 
speed motor controllers, and switch mode power supplies; and 2) impulse 
noise, mostly generated by arcing on power lines, electric fences, and 
neon signs.
