See "Starting the diagnostic programs" on page 84 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.
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 server.
4. Your software program is OK.
If the diskette drive in-use light stays on, or the system continues to bypass the
diskette drive, call for service.
1. The cables for all external SCSI options are connected correctly.
2. The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
3. Any external SCSI option is turned on. You must turn on an external SCSI option
before turning on the server.
For more information, see your SCSI and expansion enclosure documentation.
