Troubleshooting
Diagnostic LEDs
The four diagnostic LEDs on the front bezel of the server are used for diagnosing the health of
the server. See the SEL and FPL logs for specific information about the warning or failure
indicated by the diagnostics LEDs.
These LEDs warn of impending hardware failures and enable you to take preventive action, such
as making a system backup or replacing a component before it fails. These diagnostic LEDs are
labeled 1, 2, 3 and 4.
The location of red LEDs can be used to identify the category of the fault or warning. For
example, if LED one is red, there is a problem with memory. However, if LEDs one and two are
both red, there is a problem with the processor.
If the diagnostic LEDs indicate an error, check the SEL.
The following symbols are used in the LED tables.
The faults and warnings fall into several general categories.
■ The system LED indicates the severity of the error. Check this LED before
proceeding to analyze the sequence of diagnostic LEDs:
Blinking orange indicates a WARNING.
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.
