I'm not sure I follow. I cannot power the unit using the EB833's plug. You cannot program something that is not getting power.Sounds like you've completed only the first step. Also, being brand new, the EB832 LEDs won't do anything until you program the outlets. It's very unlikely (not impossible) there's a hardware issue out of the box, more likely a user error. Go to their website here and follow the step by step.
Now that you have the orange light on the Apex you need to connect directly to it (as if it were an internet connection/router) then log in to the local dash to set up remote access and connect to Fusion. It's not a difficult process but you have to follow it exactly step by step.
I spoke to tech support and they agree that it sounds like a bad unit out of the box. They are RMSing me a replacement. I just have to pay a 50 dollar refundable deposit.
In the meantime they want me to complete setup using the aux power supply and powering through the head unit. Thankfully I had a plug laying around that met the power requirements.
