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 server processor.
If the diagnostic LEDs indicate an error, check the EFI shell command line interface (CLI) cli>sl e to display
the SEL for a more detailed explanations of the failure.
• The server LED indicates the severity of the error. Check the server 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 subsystem.
• Off or solid green diagnostic LEDs provide additional details about the failure.
The faults and warnings fall into several general categories. See Table 5-4 for more information.
