Figure 5-2 Diagnostic LEDs
The pattern of illuminated LEDs can 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 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 flashing YELLOW indicates a WARNING.
• System LED flashing 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 .
