The GE DOS DUP Processor Board DS200DMCBG1ABB contains three 26-pin connectors, one 40-pin connector, and 19 jumpers. The board also has 2 LEDs. The GE DOS DUP Processor Board DS200DMCBG1ABB also is populated with one 8-pin connector, one 3-pin connector, and one 2-pin connector. Due to the multiple connectors that might have cables connected to them, it is important that you document where the cables connect before you disconnect them from the board. You will find that it speeds up the installation of the replacement board and leads to fewer errors when you restart the drive.
When you disconnect the cables you must follow guidelines that prevent damage to the cables. Always hold the connector portion of the cable to disconnect the cable from the board. If you pull the cable to disconnect it, the pressure on the connector might pull the wires from the connector. This is especially important for ribbon cables due to the multiple fine wires that make up the ribbon cable. With one hand, steady the board and with the other hand hold the connector portion of the cable. Then, gently pull the cable out of the connector.
The fuses also require consideration when you plan to troubleshoot the board. If the board stops processing or a specific function seems to have stopped, a quick inspection of the board will indicate if one or both of the fuses are blown. Be sure to obtain a replacement fuse that is an exact match of the original fuse.
