Need user manual for xb7-cm modem and what cables are needed 

What Comcast/Xfinity considers a "user manual" is at the "XB7 Getting Started Guide for Installation" link on https://www.xfinity.com/support/articles/broadband-gateways-userguides

Hi there @user_eku7d1 XB7 only comes with a coax and power cord. The easiest way to activate your modem will be through the Xfinity app, it tells you step by step what to do to activate your modem. Do you mind sharing exactly the issue you are having currently?
