Coding aids installation of features such as memory, workstation adapter, and communications in a computer system. The coding indicates where to insert the feature card, the orientation of the card, and the type of card. Orientation is coded in a redundant fashion since this is a very important variable. The locks on each card are coded. The top and bottom locks are white and black, respectively. The customer merely matches the locks with other locks in the card rack. The IBM Customer Service Representative also has this code on noncustomer logic cards. The orientation is further coded by symbol labels placed at the top of each card. The size of the label placement slot helps in labeling the card with the proper label orientation. The label is placed at the top.
