Troubleshooting
If you cannot find the problem in the troubleshooting charts, go to “Starting the
diagnostic programs” on page 124 to test the server. 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 server 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 server is running correctly.
•
Reinstall the new software or new device.

the diskette drive, call for service.
