xSeries 440:Troubleshooting Guide
See "Starting the diagnostic programs" on page 33 to test the server. If the
server still does not work and running the diagnostic test programs does
not reveal the problem, call for service.
3. If your server is running correctly, reinstall the new software or new device.
Verify that:
1. The IDE channels are 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 working properly.
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 SCSI and expansion enclosure documentation.
1. Remove the first drive not recognized and try the hard disk diagnostic test again.
2. If the remaining drives are recognized, replace the drive you removed with a new
one.
1. Remove the hard disk drive being tested when the server stopped responding
and try the diagnostic again.
2. If the hard disk diagnostic runs successfully, replace the drive you removed with a
new one.
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, air is flowing from the rear of the server at the fan
grill. If there is no air flow, the fan is not working. This causes the server 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 server.
2. Make sure that the server and the monitor are turned on.
3. Try using another keyboard.
If the items above are correct, call for service.
