Introduction

This chapter provides information about powering up the MVME240x system, and functionality of the switches, status indicators, and I/O ports on the front panels of the MVME240x and PMCspan modules.

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 power-up or system reset. The firmware initializes the devices on the MVME240x module in preparation for booting the operating system.

The firmware 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. Refer to Chapter 6 for further information about modifying defaults.

The following flowchart shows the basic initialization process that takes place during MVME240x system start-ups.

For further information on PPCbug, refer to Chapter 5, PPCBug; to Appendix D, Troubleshooting the MVME240x; or to the PPCBug documentation listed in Appendix A.
