Identifying Startup Problems
Startup problems are commonly due to the source power or to a poor cable connection.
When you start up the SCE 2000 platform for the first time, you should observe the startup sequence
described in the
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:
