Diagnostic Steps
This section describes possible reasons and actions to take when an LED indicates a fault condition during
initial system setup. Refer to the descriptions of LED statuses.
In addition to monitoring LEDs via line-of-sight observation of the racked hardware components when
performing diagnostic steps, you can also monitor the health of the system and its components using the
management interfaces previously discussed. Bear this in mind when reviewing the
