Diagnostic panel LEDs The following illustration shows the LEDs on the diagnostics panel inside the server. CPU VRM MEMORY PCI BUS 1 2 POWER SUPPLY FAN REMIND DASD NMI SERVICE PROCESSOR BUS NONREDUNDANT TEMPERATURE The system-error LED on the operator information panel is lit when certain system errors occur. If the system-error LED on your server is lit, you can check the diagnostics panel to see if any LEDs are lit. You can determine the cause of the error and the action you should take by checking the table at "Diagnostic panel system error LED" on page 132. Notes: 1. Depending on your server model, these items might appear in a different orientation on the LED panel. 2. The server supports a maximum of three PCI buses. 3. See the documentation that comes with the system-management software for more information about the service processor. Remind button You can use the Remind button to place the front panel system-error LED into the Remind mode. By pressing the button, you acknowledge the failure but indicate that you will not take immediate action. If a new failure occurs, the system-error LED will turn on again. In the Remind mode, the system-error LED flashes every 2 seconds. The system-error LED remains in the Remind mode until one of the following situations occurs: v All known problems are resolved v The system is restarted v A new problem occurs You can use the Remind button to delay server maintenance until a later time. Also, resetting the system-error LED enables the LED to react to another error. If the LED is still on from the first error, it will not indicate additional errors. If you press the Remind button (causing the LED to flash every 2 seconds) and another error occurs, the LED will stop flashing and will instead be lit continuously to alert you to the new error.
