The engineers’ intent for lamp board replacement is to replace the board from the top. The assembly should not be removed from the bottom because the holes in the woodwill strip out.
The lamp board is Lamp 200, part number 1005523-02.
The cover is called LED Board Cover, part number 1005571-01.
It is a little difficult to get the cover out on some of the desks. You can use a piece of tape or a small tool to lift up the cover from the screw hole. The board should not be pried from the edge because it damages the top.
