Dell Blade PE1955 power plug

[Irwan Hadi]

We are ordering a Dell PE1955 chassis. Now the question is what kind
of power plug does Dell PE1955 chassis require?
Based on the PE1955 specs at
http://www.dell.com/downloads/global/products/pedge/en/pe1955_spec_sheet.pdf
 , it requires 208 V and will pull about 2100 watts of power, but
doesn't say what the end is.

Will a standard C19 plug works, or will we need to get a NEMA L6-20 plug?

Thanks
