Check the system LED before proceeding to analyze the sequence of diagnostic LEDs: • System LED blinking yellow indicates a warning. • System LED blinking red indicates a fault. • The diagnostic LEDs provide details about the specific error: • Solid red indicates the failing part or sub-system. • Off or solid green diagnostic LEDs provide additional details about the failure. The pattern of illuminated LEDs may be used to identify the category of the fault or warning. For example, if diagnostic LED one is red, there is a problem with memory. However, if diagnostic LEDs one and two are both red, there is a problem with the system processor. If the diagnostic LEDs indicate an error, check the EFI shell command line interface (CLI) cli>sl e to display the system event log (SEL) for a more detailed explanations of the failure.
