Troubleshooting
Printer problems Action
The printer does not
work. Verify that:
1. The printer is turned on and is online.
2. The printer signal cable is connected to the correct
parallel, serial, or USB port on the system. For the
location of the parallel, serial, and USB ports, see
“Input/output connectors” on page 11.
Note: Non-IBM printer cables might cause
unpredictable problems.
3. You have assigned the printer port correctly in
your operating system or application program.
4. You have assigned the printer port correctly using
the Configuration/Setup Utility program. For
information on using the Configuration/Setup
Utility program, see “Using the
Configuration/Setup Utility program” on page 39.
If the items above are correct and the printer still does
not work, run the tests described in the documentation
that comes with your printer. If the tests show that the
printer is OK, have the system serviced.
Expansion enclosure
problems
Action
The SCSI expansion
enclosure used to work,
but does not work now. Verify that all SCSI expansion enclosure hardware and
cable connections are secure.
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. An external SCSI option is turned on. You must
turn on an external SCSI option before turning on
the system.
For more information, see your SCSI and expansion
enclosure documentation.
If the SCSI expansion enclosure comes with its own test
instructions, use those instructions to test it. In
addition, test the power supply.
If the items above are correct and the test programs
found no problem, have the server and SCSI expansion
enclosure serviced.
