Troubleshooting Possible Problems The system will not boot. Step 1. Examine the display panel LEDs for warning or fault indications. The system LED will be flashing yellow with a warning indication and flashing red with a fault indication. Step 2. Examine the four diagnostic LEDs for indications of specific warning or fault indications. The diagnostic LEDs present patterns that categorize the source of the warning or fault. Step 3. Display and examine the system event log (SEL) and forward progress log (FPL) for further information relating to warning or fault indication. Step 4. Review the firmware revisions of all firmware. Step 5. Use the BMC command line interface (cli) to cycle the system power, cli>pc off, cli>pc on. Step 6. Turn the server off, wait at least twenty seconds, then turn the server back on to see if the failure can be cleared. Step 7. Check that all DDR DIMMs are seated properly. Step 8. Check that the DDR DIMM configuration on the system board matches those approved. A minimum of one DDR DIMM pair must be installed. Step 9. Verify that the DIMMs are fully seated. When the DIMM is fully seated in the mating connector, the retaining latches are closed (they should be flush with the front of the DIMM). If the latches are not closed, reseat the DIMM fully by engaging the retaining latches and closing them fully. Step 10. Check that the processors are installed in the correct sockets and that each processor has a power pod installed. Also verify that the processors are of the same type. Step 11. Check the boot order with the SCSI configuration utility. Step 12. If there are no obvious errors, reflash the BMC firmware. Refer to "Utilities" in the hp Integrity rx1620 Operations Guide. Step 13. If the system will still not boot, it may be necessary to replace the base unit. The system has intermittent failures. Step 1. Examine the display panel LEDs for warning or fault indications. The system LED will be flashing yellow with a warning indication and flashing red with a fault indication. Step 2. Examine the four diagnostic LEDs for indications of specific warning or fault indications. The diagnostic LEDs present patterns that categorize the source of the warning or fault. Step 3. Display and examine the system event log (SEL) and forward progress log (FPL) for further information relating to warning or fault indication. Step 4. Make sure that the system fan assemblies are fully seated. Step 5. Verify that the server is plugged into a power source that is within specifications described on the label of the power supply. Step 6. Make sure that the internal SCSI chain is terminated and that termination is not enabled on any of the drives. Note that with LVD SCSI, termination is provided in the cable. Step 7. Check that the processors are installed in the correct sockets and that terminators are installed in all unused sockets. Chapter 4 49
