While not a comprehensive diagnostic tool, status indicators (LEDs) located on the chassis and on selected system components can serve as front-line indicators of a limited set of hardware failures.
You can view LED status by direct inspection of the system front and back panels and on some components and ports. You also can view the status of certain LEDs from the Oracle ILOM web interface or command-line interface. The Oracle ILOM Fault Management Shell allows you and Oracle Service personnel to view and manage fault activity on servers and other types of devices.
The green System OK LED indicator and the green SP OK indicator remain lit (no blinking) when the server is in a normal operating state. For any LED color other than green or if the LED is blinking, refer to the Troubleshooting chapter in the Service Manual for your platform.
