The Silicon Tracking System will be installed into the superconducting dipole magnet, providing sufficient aperture to receive it's 2 m$^3$ volume, the vacuum chamber with target and Micro Vertex Detector, and the beam pipe. The detector system breaks down into eight tracking stations, built from a total of 106 carbon fiber ladders with 896 detector modules comprising 1220 silicon microstrip sensors, a total of about 2 millon read-out channels. The system integration effort is presented to mount the ladders with high mechanical accuracy and stability. The sensors will be operated at -5 $^\circ$C, to be achieved with a gas flow. The read-out electronics dissipates about 40~kW which will be evacuated with a CO2 cooling system. Solutions to route the supplies and services in the confined space will be discussed, as well as precautions to enable access to the components in case of repair.
