C7 not setting up

Ok, then log in to the Diagnostic Tools page using your MAC address. Do a Soft Reset, then try to restore a firmware version (if any versions show). I doubt you will find a version on there to restore, and it looks like yours is one of the rare ones that didn't get a platform installed at manufacture. The good news is that you can get to the diagnostic tools menu, so it will be able to be fixed without sending it back.

I suspect that your Hub, which appears to be working, doesn't have a valid platform software installed. There's a process documented at the link below, but you may want to contact support (tagging @bobbyD) because it might be best if they walked you through it. It's a bit scary:

Send an email to support (click the support link at the top of this page) and they will contact you and walk you through the factory restore process for a C-7 with blue light out of the box.

On second thought, don't do the above. If the diagnostic tools menu shows that a platform is installed, then try the soft reset and try to restore a firmware version - several versions are kept on the hub. If that doesn't work, then email support.
