The GE UC2000 Motherboard DS200UCIAG2A features one microprocessor and multiple PROM modules. It also contains 1 block of 10 LEDs and 2 50-pin connectors. The GE UC2000 Motherboard DS200UCIAG2A also is populated with 1 jumper and 1 connector to support the attachment of other boards. The board also has 3 3-pin connectors. One 3-pin connector is assigned the ID Gen1. One 3-pin connector is assigned the ID Gen2, and the final 3-pin connector is assigned the ID Fan.
When you plan to replace the board, inspect the board while it is still installed in the drive with all the cables connected to it. Write on masking tape the IDs and tape them to the cables connected to the 3-pin connectors. Do the same to all the other cables. This especially valuable for the 50-pin ribbon cables. The ribbon cables carry signals to other components and boards in the drive. Other signals in the ribbon cable carry signals that are received by the board. The signals are carried by a few strands of thin copper wire and if the connection between the connector and the wires is lost, the signal will be lost also. To avoid disconnecting the signal, hold the ribbon cable by the connector only when you disconnect it from the ribbon cable. Avoid pulling the ribbon cable to disconnect it because it puts stress on the wire strands and might cause them to break. To connect the 50-pin ribbon cables, hold the connector at the end of the ribbon cable and gently press it into the connector on the board.
