Troubleshooting charts You can use the troubleshooting charts in this section to find solutions to problems that have definite symptoms. Attention: If diagnostic error messages appear that are not listed in the following tables, make sure that your system has the latest level of BIOS code installed. Refer to the "Solving problems" section in the User's Reference on the IBM xSeries Documentation CD for more detailed information about testing the system. If you have run the diagnostic test programs or if running the tests does not reveal the problem, call for service. Look for the symptom in the left column of the chart. Instructions and probable solutions to the problem are in the right column. If you have just added new software or a new option and your system is not working, do the following before using the troubleshooting charts: • Remove the software or device that you just added. • Run the diagnostic tests to determine if your system is running correctly. • Reinstall the new software or new device.

All cables and cords are connected securely to the rear of the system and attached options. 2. When the system is turned on, air is flowing from the rear of the system at the fan grille. If there is no air flow, the fan is not working. This causes the system to overheat and shut down. 3. Ensure that the SCSI bus and devices are configured correctly and that the last external device in each SCSI chain is terminated correctly. If the items above are correct, call for service.
