PrPMC800/800ET Processor PMC Module Installation and Use (PrPMC800A/IH5)

2 Operating Instructions

Introduction

This chapter provides information about powering up the PrPMC800/800ET system, and

functionality of the status indicators, and I/O ports on the PrPMC800/800ET module.

Applying Power

After you have verified that all necessary hardware preparation has been done, that all

connections have been made correctly, and that the installation is complete, you can power up

the system. The MPU, hardware and firmware initialization process is performed by the

PPCBug firmware at power-up or system reset. The firmware initializes the devices on the

PrPMC800/800ET module in preparation for booting the operating system.

The firmware, PPCBug, is shipped from the factory with an appropriate set of defaults. In most

cases there is no need to modify the firmware configuration before you boot the operating

system. However, if you choose to do so, refer to Chapter 6, Modifying the Environment for

further information about modifying these defaults.

The following flowchart shows the basic initialization process that takes place during

PrPMC800/800ET system start-up.

For further information on PPCBug, refer to Chapter 5, PPCBug, or to the PPCBug

documentation listed in Appendix C, Related Documentation.
