Identifying Startup Issues

Startup issues are commonly due to a powers source issue or a poor cable connection.

This section describes 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.
