Diagnostic Leds - HP Integrity rx2620 User's & Service Manual

Diagnostic LEDs

The server has four diagnostic LEDs. These diagnostic LEDs warn of impending or
existing failures and enable you to take preventive or corrective action, such as making
a server backup or replacing a component. These diagnostic LEDs are labeled 1, 2,
3, and 4.
If no iLO MP is installed, the boot progress is monitored by diagnostic LEDs 1
through 4. During the boots, the LEDs turn on in sequence until the EFI prompt
is reached.
If an iLO MP is installed, the boot process is monitored by the iLO MP. The
diagnostic LEDs are disabled. For more information, see
Figure 83 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
