Troubleshooting charts

You can use the troubleshooting charts in this section to find solutions to problems
that have definite symptoms.
Attention:
tables, make sure that your system has the latest level of BIOS code installed.
See the Troubleshooting Guide 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

xSeries 440:Installation Guide
If diagnostic error messages appear that are not listed in the following
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.
Verify that:
1. The primary IDE channel is enabled in the Configuration/Setup Utility program.
2. All cables and jumpers are installed correctly.
3. The correct device driver is installed for the CD-ROM drive.
If there is a diskette in the drive, verify that:
1. The diskette drive is enabled in the Configuration/Setup Utility program.
2. The diskette is good and not damaged. (Try another diskette if you have one.)
3. The diskette contains the necessary files to start the system.
4. Your software program is working properly.
If the diskette drive in-use light stays on, or the system continues to bypass the
diskette drive, call for service.
Call for service.
Verify that:
1. 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.
1. Make sure that the keyboard cable is properly connected to the system.
2. Make sure that the system and the monitor are turned on.
3. Try using another keyboard.
If the problem remains, call for service.
