You can either give it 5 volts via a barrel connector, or let it be powered via USB using the micro USB connector next to the power switch. You need to move a jumper to select which source is actually powering the board. (A third option is powering the board from a battery).
They offer a 5 volt 2.5 amp wall wart for it, but state this it will draw only 0.2 amps idling and will work fine from a 0.5 amp limited USB 2.0 cable. It is not clear yet to me when it would pull more than 0.5 amps of current, but apparently it can.
I find a cable and plug it in. There are no signs of life, but that is because the power switch is in the off position. As soon as I turn it on I see a red led come on (labeled "pgood" i.e. power good?) and the following in my linux system log:

Apparently the FT2232H chip handles two serial ports via a single USB connection which is kind of nice. I believe one is for JTAG and the other is for a console terminal. Oddly enough the schematic omits details about how this is connected.
