No connections, not booting? 

Hi folks,
I have installed a CB1 on the adapter and flashed Raspberry Pi Images to SD with WiFI, SSH, and all the common Stuff for first signs of life needed. When I try to connect via SSH, I permanently get Errors, that the device is not found. In my Router I don't get any IP-Addresses. On the board I find only one LED lighting up, but no send/receive signals. 
eMMC doesn't work too.
