Troubleshooting Charts - IBM eServer 380 xSeries User Reference Manual

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 server has the latest levels of BIOS and firmware
installed.
See "AMIDiagnostic program" on page 57 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

xSeries 380: User's Reference
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 BIOS Setup Utility program.
2. The correct device driver is installed for the CD-ROM drive.
If the problem remains, call for service.
If there is a diskette in the drive, verify that the diskette is good and not damaged. (Try
another diskette if you have one.)
If the diskette drive in-use light stays on, or the system continues to bypass the
diskette drive, call for service.
Verify that:
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 expansion enclosure documentation.
Call for service.
Verify that:
1. All cables and cords are connected securely to the rear of the server and
attached options.
2. When the server is turned on, verify that the power supply and fan indicator lights
are off.
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 and the problem remains, call for service.
