The GE Insulated Gate Bipolar Transistor (IGBT) Board DS200IIBDG1ACA contains nine indicator LEDs that provide a status of the processing of the board. The LEDs are visible from the interior of the circuit board cabinet and are red in color when lit. A 32-pin ribbon cable connector is contained on the board and during the replacement procedure you must consider the proper procedure to disconnect and connect the ribbon cable.
The ribbon cable is made of fine wires which are easily broken or disconnected from the connector. If any of the fine wires is disconnected the signal it carries will not be sent to the board or received by the board. The ribbon cable has two tabs on either side that secure the connector in place. To remove the ribbon cable, grasp the connector on both sides of the connector and at the same time release the two tabs. Then, pull the connector out from the board.
To remove the board from the drive, remove the four screws that hold the board in place. Make sure you keep the four screws together and store them in a safe place for future use. Hold the board by the edges and pull out the board from the drive cabinet. Place the board on a flat surface that is free of dirt, dust, and debris. Remove the replacement board from the static protective bag, flatten the bag on a clean surface, and place the board on the bag.
