Introduction; Applying Power - Motorola MCP750HA Series Installation And Use Manual

Introduction

This chapter provides information applicable to the MCP750HA family of
Single Board Computers in a system configuration. This includes the
power-up procedure along with descriptions of the switches and LEDs,
memory maps, and software initialization.

Applying Power

After you have verified that all the necessary hardware preparation has
been done (with all connections 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 PowerPC™ PPCBug
power-up or system reset. The firmware initializes the devices on the SBC
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.

When using the MCP750HA in a hot swap capable chassis, the module
may be inserted and extracted with power applied.
For additional information on PPCBug, refer to
Chapter 6, CNFG and ENV
