Overview

This chapter supplies information for use of the MVME2700 series of

single board computers in a system configuration. Here you will find the

power-up procedure and descriptions of the switches and LEDs, memory

maps, and software initialization.

Power-up the System

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 MVME2700 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.

The flowchart in Figure 2-1 shows the basic initialization process that

takes place during system startup.

For further information on PPCBug firmware, refer to Chapter 5, PPCBug

Firmware and to the PPCBug Firmware User’s Manual, listed in

Appendix D, Related Documentation.

Switches and LEDs

The MVME2700 front panel has ABORT and RESET switches and six LED

(light-emitting diode) status indicators (

CHS, BFL, CPU, PCI, FUS, SYS).

The switches and LEDs are mounted on an LED mezzanine board that

plugs into the base board.
