8.2. Remove the Boards 

First remove all the connectors from the board. During this you have to draw the position and direction of the cables connected with the board. After removing the boards you have to distinguish between them. At first they will look similar but if you carefully look on them you can distinguish between them. For example you can distinguish by the numbers on the ICs on the boards. You need not the function of a board. You need only to note from which slot it comes and how it s connected to other components so that you do not fall in problems during reassembling the components.
