Troubleshooting Recommendations:

  1. Swap BMC 2 with BMC 1.

    1. If system checks are good, replace BMC 2 and do close out.
    2. If fault remains, continue with next step.

  2. Perform wiring checks between BMC 1, JB3 and BMC 2.

    1. If wiring checks are not good, repair defective wiring as required and do close out.
    2. If wiring checks are good, continue with next step.
      NOTE: Remove all interface components for short test.

  3. Replace PCB1/JB3.
  4. Do close out.
