This will avoid problems associated with plugging the ribbon cables in to the wrong connector.
The jumpers are set by an installer to configure the board to send and receive signals and process information as needed for the drive function. The jumper positions are recorded and saved with other important information concerning the drive. Before you install the replacement drive, set the jumpers to match the original board as recorded by the installer of the original board.
