Thermal padding

Position two layers of thermal pad on top of the surface of the P&CB that is in contact with the cooling block (large connector side). Two inductors on this side will be visibly coming out from under the thermal pad. These chips have enough height to be in direct contact with the cooling block, and there is no margin for a thermal pad there. Gently remove the thermal pad from the top of the inductors until the inductor becomes visible.

This is how it should look like

Now as a final step, position a kapton tape on the fragile fiber optics cable so it holds the cable from moving, and hence, breaking to small wires within. This is how it should look like.

Hooking up the carrier

This is the most delicate step of them all. The carrier wire bonds are exposed, and something as little as a strong breeze or a light touch may damage them, so proceed with extreme caution.

Now from the external side of the cover, slide in the MTP adapter from the clipper side into the cover. Use 5/64'' screws to fasten the fiber optics MTP adapter to the cover as well. Any orientation should be ok.  You final work should look like this.

Now gently insert the other side of the power cable in the P&CB. Orientation matters. The connector extrusion should be to the upper side. Now connect the Fiber optics cable to the MTP adapter. Orientation also matters. This is how your setting should look like now

As a final step, you need to close the cover without jeopardizing the cables. The covers may be stuck due to fitting issues, but another possible reason is that the cables are trapped somewhere, so proceed with extreme caution. The thick cable can be extended in all the available space. The Fiber optics can be rotated in a circle under the cover. Your final setup should now look like this.

Congratulations. You are done.
