Tnx hurricandave, for answering the first part of this question, which they indeed still state on bitmaintech.com.

The second question remains open to BITMAIN:

There seems to be not so much space for the LAN-cable to enter the socket of the horizontally mounted S1 controller board. Could you please provide a picture with a ordinary network cable inserted on bitmaintech.com or should one go with a right angled connector anyway.
