Option problems Action
An IBM option that was just
installed does not work. Verify that:
1. The option is designed for your server. For a list of
supported options, refer to http://www.ibm.com/pc/us/compat/
on the World Wide Web.
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 Configuration/Setup Utility
program.
If all of the above items are correct, start the diagnostic
programs. If the diagnostic 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. (Refer to the User's
Reference on the IBM xSeries Documentation CD for more
information on SCSI termination.)
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.
Serial port problems Action
The number of serial ports
displayed is less than the
number of serial ports
installed. Verify that:
1. Each port is assigned a unique address.
2. The serial-port adapter, if you installed one, is seated
properly.
If the items above are correct, have the system serviced.
