Troubleshooting
Option Problems Action
An IBM option that was
just installed does not
work.
Verify that:
1. The option is designed for the system.
2. You followed the installation instructions that were
supplied with the option.
3. The option is installed correctly.
4. You have not loosened any other installed options
or cables.
5. You updated the configuration information.
Whenever you change the memory or an option,
you must update the configuration by running the
System Configuration Utility program (see
Chapter 3, “Configuring Your Server” on page 39).
If all of the above items are correct, start the test
programs. If the test programs find no problem, have
the system and the option serviced.
An IBM option that used
to work does not work
now.
Verify that all of the 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 items above are correct and the test programs
found no problem, have the system and the option
serviced.
If the failing option is a SCSI option, 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. (See “SCSI
Drives” on page 159 for more information on SCSI
terminators.)
3. All external SCSI options are turned on. External
SCSI options must be turned on before the system
is turned on.
If the problem recurs, have the system serviced.
Parallel Port Problems Action
The number of parallel
ports displayed is less
than the number of
parallel ports installed.
Verify that:
1. Each port is assigned a unique address.
2. The parallel-port adapter, if you installed one, is
seated properly.
If the items above are correct, have the system
serviced.
