Troubleshooting Continued:
1. Refer to the
Power Distribution
discussion in Section 4. Refer to the
Remote CPU Assembly Schematic
in Section 6 if it is necessary to
make voltage checks at the chip or component level.
2. If the power is functioning properly, the microprocessor is not function-
ing. The microprocessor requires a clock, a power-up reset, and com-
munications from the system controller. Refer to the GPIO Interface
Card functional description in Section 4.
