[j-nsp] MX960 Power Options

[Colton Conor]

What are the options for powering a MX960 using AC power? The datacenter
provider is offering us power  in the following options:

120V/20AMP A/B Power
120V/30AMP A/B Power
208V/30AMP A/B Power

We are leaning towards using a MX960 with 4 AC power supplies and limited
cards installed. More than likely we will order the 208V/30AMP A/B Power
from the datacenter, but want to know if this will be enough? What does
Juniper recommend?
