7 ACC-CX3RDK-CU5640 Board handling procedure
The ACC-CX3RDK-CU5640 Board should be mounted to Camera header (CN10) of the
DENEBOLA_CX3_RDK Baseboard as indicated in the following steps
1. Top and bottom view of camera board are shown in the images below.

2. The camera board should be inserted into the Camera header (CN10) of the
DENEBOLA_CX3_RDK Baseboard before powering ON the DENEBOLA_CX3_RDK
Baseboard. Note that the camera board will be positioned inside the board and camera
module will be perpendicular to the camera header. Since the camera board connector is
polarized, you can mount it on only one side as shown in the image.

3. Power up the DENEBOLA_CX3_RDK Baseboard (Refer the DENEBOLA_CX3_RDK
hardware user manual). After powering ON the DENEBOLA_CX3_RDK Baseboard, the
Green color LED on Baseboard will glow as shown in the image below. This serves as an
indication for power-up of Baseboard.
