Troubleshooting

Possible Problems

Step 3. At this point you will have a good idea about which area of the system requires further analysis. For example, if the

symptom was “system will not power-up” then the initial troubleshooting procedure may have indicated a problem

with the DC power supply not coming up after the power switch was turned on.

Step 4. You have now reached the point where the failed Field Replaceable Unit (FRU or FRUs) have been identified and

need to be replaced. You must now perform the specific remove and replace and verification steps.

NOTE If multiple FRUs are identified as part of the solution, a fix cannot be guaranteed unless all

identified failed FRUs are replaced.

Step 5. There may be specific recovery procedures you need to perform to finish the repair. For example, if the display

panel is replaced, you will need to restore customer specific information.

Possible Problems

This section contains example HP Server problems and their possible solutions.

The system will not power-up.

Step 1. Review the installation procedures for the server. Refer to the hp Integrity rx1600 Installation Guide.

Step 2. Check all power connection cables.

Step 3. Verify that power is available at the AC power receptacle. Check the receptacle output with another device.

Step 4. Check the power supply fans to see if they are operating. The fans will operate off of the dc voltage generated by

the power supply.

Step 5. Check that the STBY (power good) LED located near the SCSI connector on the system board is illuminated.

Step 6. Check all connections from the power supply to the power distribution module.

Step 7. Verify that all cables and modules are correctly connected. Especially check the display panel connection.

Step 8. If the system starts to power on and then power off, a voltage rail of the power supply may be out of specification.

The BMC monitors voltages and prevents power on when power values are out of specification.

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.
