Performance And Lockup Problems - Lenovo 0896 User Manual

An option that previously worked does not work now
Symptom: An option that previously worked does not work now.
Actions:
• Verify that all option hardware and cable connections are secure.
• If the option comes with its own test instructions, use those instructions to test the option.
• If the failing option is a SCSI option, verify that:
– 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.
– All external SCSI options are turned on. External SCSI options must be turned on before the computer
is turned on. For more information, see your SCSI documentation.
• Verify that the option and any required device drivers are installed correctly.
If these actions do not correct the problem, run the diagnostic programs (see "Diagnostic programs" on
page 110 for instructions). If you need technical assistance, see Chapter 11 "Getting information, help, and
service" on page 113.
