Troubleshooting
Keyboard, Mouse,
or Pointing-
Device Problems Action
All or some keys on the
keyboard do not work.
1. Make sure that the keyboard cable is properly connected to the
system.
2. Make sure that the system and the monitor are turned on.
3. Try using another keyboard.
If the items above are correct, have the system serviced.
The mouse or pointing
device does not work.
1. Verify that the mouse or pointing-device cable is securely connected
and the device drivers are installed correctly.
2. Try using another mouse or pointing device.
If the problem still exists, have the server and the device serviced.
Memory Problems Action
The amount of memory
displayed is less than the
amount of memory
installed.
Verify that:
1. The memory modules are seated properly.
2. You have installed the correct type of memory (see “Working with
Memory Modules” on page 54).
3. If you changed the memory, you updated the memory configuration
with the Configuration/Setup Utility program program. For information
about using the Configuration/Setup utility programs, see “Using the
Configuration/Setup Utility” on page 22.
4. All banks of memory on the DIMMs are enabled (see “Advanced
Setup” on page 28). The Netfinity 5000 server might have
automatically disabled a DIMM bank when it detected a problem or a
DIMM bank could have been manually disabled.
If the above items are correct, run the memory test from the Diagnostic
Utility menu. The system might have detected a bad memory module and
automatically reallocated memory to enable you to continue to operate. If
the memory tests fail, have the system serviced or replace the failing
DIMM.
Option Problems Action
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 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.
3. Any external SCSI option is turned on. You must turn on an external
SCSI option before turning on the system.
If the problem still exists, have the server and option serviced.
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 come 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 in the Configuration/Setup
Utility program program. Whenever memory or an option is changed,
you must update the configuration. For information about using the
Configuration/Setup utility programs, see “Using the
Configuration/Setup Utility” on page 22.
If the problem still exists, have the server and option serviced.
