IBM xSeries 135: User's Reference
Verify that:
• The primary IDE channel is enabled in the Configuration/Setup Utility
program.
• All cables and jumpers are installed correctly.
• The correct device driver is installed for the CD-ROM drive.
If there is a diskette in the drive, verify that:
• The diskette drive is enabled in the Configuration/Setup Utility program.
• The diskette is good and not damaged. (Try another diskette if you have one.)
• The diskette contains the necessary files to start the server.
• 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.
• The cables for all external SCSI options are connected correctly.
• The last option in each SCSI chain, or the end of the SCSI cable, is terminated
correctly.
• 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.
Call for service.
Verify that:
• All cables and cords are connected securely to the rear of the server and
attached options.
• When the server is turned on, air is flowing from the rear of the server at the
fan grill. If there is no airflow, the fan is not working. This causes the server to
overheat and shut down.
• 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 problem persists, call for service.
• Make sure that the keyboard cable is properly connected to the C2T device
breakout cable.
• Make sure that the C2T device breakout cable is properly connected to the
server.
• Make sure that the server and the monitor are turned on.
• Try using another keyboard.
If the problem persists, call for service.
