    Notes:

    1. The ribbon cable is labeled System Planar.
    2. The ribbon cable is pre-folded so that it automatically follows the correct route inside the SAN Volume Controller 2145-4F2.
11. To reinstall the cables, carefully install the one end of the ribbon cable (marked System Planar) to the system board being sure to install the cable straight in. See Figure 2.
12. Route the flat cable and feed it through the opening where the service controller is to be installed and bring the other end of the cable (marked Controller Card) out of the front end of the SAN Volume Controller 2145-4F2 chassis. Carefully install this other end of the cable to the rear of the service controller, being sure to install the cable straight in with no rocking or twisting during installation.
13. Install the ATA cable to the rear of the service controller.
14. Carefully install the service controller while ensuring the cables do not get damaged as they slide into the chassis.
15. Verify that the blue line on each of the cable connector ends is not visible. This ensures that it is fully seated. For more information, see the documentation on removing the service controller from the SAN Volume Controller 2145-4F2.
