Identifying Startup Problems

Startup problems are commonly due to the source power or to a poor cable connection.
When you start up the SCE 1000 platform for the first time, you should observe the startup sequence
described in Starting the SCE 1000 Platform. This section contains a more detailed description of the
normal startup sequence and describes the steps to take if the system does not perform that sequence as
expected. LEDs indicate all system states in the startup sequence. By checking the state of the LEDs,
you can determine when and where the system failed in the startup sequence. Use the following
descriptions to isolate the problem to a subsystem, and then proceed to the appropriate sections to try to
resolve the problem.
When you start up the system by turning on the power supply switch, the following should occur:

You should immediately hear the fans operating.
When all LEDs come on to indicate that the system has booted successfully, the initial system
banner should be displayed on the console screen. If it is not displayed, see How to Set Up the Local
Console to verify that the terminal is set correctly and that it is properly connected to the console
port.
