Diagnostic LEDs

Four diagnostic LEDs are provided on the display panel of the system. Additional diagnostic
LEDs are provided on the system board and are described later in this chapter.
The diagnostic LEDs warn of impending failures or present failures and allow you to take
preventive or corrective action, such as making a system backup or replacing a component. These
diagnostic LEDs are labeled 1, 2, 3 and 4.
• If no management processor card is installed, the boot progress is monitored by diagnostic
LEDs 1 through 4. During the boot-up the LEDs will turn on in sequence until the EFI prompt
is reached.
• If a management processor card is installed, the boot process will be monitored by the
management processor card. The diagnostic LEDs are disabled.

• The system LED indicates the severity of the error. 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.
The faults and warnings fall into several general categories.
