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
“Basic SCE 2000 Platform Operations” section on page 7-1
. 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.
