Product Description

The GE Protective Termination Expander Board DS200TCEBG1BAA features 3 bayonet connectors, 4 signal transformers, and 1 26-pin connector. It also contains 4 10-pin connectors and 3 20-pin connectors. The signal transformers that populate the board are used to increase the compatibility of the signals between two devices. The board is also populated with 3 20-pin connectors. The 20-pin connectors are labeled JKZ JKX, and JKY. The 20-pin connectors are connected to signal carrying ribbon cables. The signal are transmitted to the board from other boards in the interior of the drive. Other signals are transmitted to other boards in the drive.

Ribbon cables are made up of fragile fine wires so they require some special consideration when you disconnect them or connect them. When you plan to disconnect the 20-pin ribbon cables, it is important that you first attach a tag or label to them that IDs the connector that it is attached to. Doing that will reduce the opportunity to connect the ribbon cable into the wrong connector and thereby force the installer to reconnect the cables and delay when the drive is back online.

Once the ribbon cables are labelled, hold the ribbon cable connector at the end of the cable and gently pull it out of the connector. If necessary, use your other hand to hold the board and keep it from moving. Move the ribbon cable aside so you can access the board. However, do not disturb the cable routing. The ribbon cable is routed to reduce interference that can be caused by running the ribbon cable in parallel with power cables.
