LED None OVER SPEC PS 1 PS 2 CPU VRM CNFG MEM NMI S ERR SP DASD Note: When there is a reference to an error log in the following table and your model has the optional Remote Supervisor Adapter II SlimLine option installed, view the system event error log; otherwise, view the POST error log. The two error logs are located on the Configuration/Setup Utility in the Event/Error logs option. For more information, see the User's Guide. Problem Action An error has occurred and cannot be Check the system error log for information about the error. diagnosed, or the ASM processor has failed. The error is not represented by a Light Path diagnostics LED. The power supplies are using more power than their maximum rating. Replace the failing power supply, or remove optional devices from the server. When the LED is lit, the power supply in bay 1 has failed. When the LED flashes, an invalid power-supply configuration has occurred. If the power supply has failed, call for service. If a configuration error has occurred, make sure that the power supply is installed correctly. When the LED is lit, the power supply in bay 2 has failed. When the LED flashes, an invalid power-supply configuration has occurred. If the power supply has failed, call for service. If a configuration error has occurred, make sure that the power supply is installed correctly. When the LED is lit, a microprocessor has failed. When the LED flashes, an invalid microprocessor configuration has occurred. If a lit LED on the system board indicates a problem with a microprocessor, make sure that the microprocessor is installed correctly. See the Option Installation Guide on the IBM xSeries Documentation CD for information about installing a microprocessor. If the problem remains, call for service. If a configuration error has occurred, make sure that the microprocessors have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. When the LED is lit, an error occurred Replace the VRM. If the problem remains, call for service. on the microprocessor voltage regulator module (VRM). When the LED flashes, If a configuration error has occurred, make sure that the VRM is an invalid VRM configuration has installed correctly. If the problem remains, replace the VRM. occurred. When the LED flashes, a hardware configuration error has occurred. Check the system error log for information about the error. The Light Path diagnostic LED for the component that is causing the configuration error also flashes. When the LED is on, a memory error has occurred. When the LED flashes, an invalid DIMM configuration has occurred. Replace the failing DIMM, which is indicated by the lit LED on the system board. If a configuration error has occurred, make sure the DIMMs are installed correctly. A machine check error has occurred. Check the system error log for information about the error. A soft error has occurred. Check the system error log for information about the error. The service processor has failed. Remove ac power from the server; then, reconnect the server to ac power and restart the server. A hard disk drive error has occurred. If the problem remains, call for service. Check the LEDs on the hard disk drives and replace the indicated drive. Chapter 6. Solving problems 67
