HELP

Just received my Antminer S4 and having a difficult time setting it up.  When turning the machine on it whirls at full speed/noise, but never settles down.  The LCD screen is bright but never displays any text.  Anyone know what the issue is?

This occurs whether directly plugged into my computer, or plugged into a Netgear N300 wifi to Ethernet adapter.  I unscrewed the lid, and all of the cables appear to be plugged in properly.
