CyberResearch® CPU Cards

The following notes show how to connect ATX Power Supply to the embedded board.1.Using ATX Power Switch

NOTE:

The following diagram describes an ATX power connection for the 1.10 version of the CPEx GX-333-X. To connect the 1.11 version of the CPEx GX-333-X to an ATX power supply, use the CN6 connector instead of the CN4 connector shown below. Refer to the CN6 connector pinouts in Chapter 2 for appropriate power button pin locations.

Step 1. Disconnect the AC cord of the Power Supply from the AC source to prevent sudden electric surge to the board.

Step 2. Remove the jumper cap on JP2.

Step 3. Your ISA interface backplane should come with the associated 5VSB and PS_ON pin connector. Usually connecting these two pins is sufficient. Also, an ATX power feature cable should come ready with your backplane. Connect CN3 to the associated connector on your backplane.
