[nsp] Sup720 Power Revisited

[Jack.W.Parks at alltel.com]

We only use DC power.  I wonder if this causes a problem?  CCO is light
on DC info.

Right on Stacy.  110V circuit effectively provides power = 1300W supply.
If you are going to invest in larger power supplies, make sure you run
the proper circuit (220V).

You also need to pay attention to 220V vs 110V lines.  If I remember 
correctly, I was told by our SE that with 110V cords, you need to run in

tandem, but with 220V you can run redundant.  Perhaps Brad can confirm?
