General checkout
The server diagnostic programs are stored in upgradable
read-only memory (ROM) on the system board. These
programs are the primary method of testing the major
components of the server: the system board, Ethernet
controller, video controller, RAM, keyboard, mouse
(pointing device), diskette drive, serial port, and parallel
port. You can also use them to test some external
devices. See “Diagnostic programs”on page 10.
Also, if you cannot determine whether a problem is caused
by the hardware or by the software, you can run the
diagnostic programs to confirm that the hardware is
working properly.
When you run the diagnostic programs, a single problem
might cause several error messages. When this occurs,
work to correct the cause of the first error message. After
the cause of the first error message is corrected, the other
error messages might not occur the next time you run the
test.
A failed system might be part of a shared DASD cluster
(two or more systems sharing the same external storage
device(s)). Prior to running diagnostics, verify that the
failing system is not part of a shared DASD cluster.
A system might be part of a cluster if:
The customer identifies the system as part of a
cluster.
One or more external storage units are attached to
the system and at least one of the attached storage
units is additionally attached to another system or
unidentifiable source.
One or more systems are located near the failing
system.
If the failing system is suspect to be part of a shared
DASD cluster, all diagnostic tests can be run except
diagnostic tests which tests the storage unit (DASD
residing in the storage unit) or the storage adapter
attached to the storage unit.
6xSeries 240 HMM

Notes
1. For systems that are part of a shared DASD
cluster, run one test at a time in looped mode.
Do not run all tests in looped mode, as this could
enable the DASD diagnostic tests.
2. If multiple error codes are displayed, diagnose
the first error code displayed.
3. If the computer hangs with a POST error, go to
the “Symptom-to-FRU index”on page 189.
4. If the computer hangs and no error is displayed,
go to “Undetermined problems”on page 210.
5. Power Supply problems, see “Symptom-to-FRU
index”on page 189.
6. Safety information, see “Safety information”on
page 224.
7. For intermittent problems, check the error log;
see, “POST Error Log”on page 33.

Diagnostic programs
The server diagnostic programs are stored in upgradable
read-only memory (ROM) on the system board. These
programs are the primary method of testing the major
components of your server, such as the the system board,
Ethernet controller, video controller, RAM, keyboard,
mouse (pointing device), diskette drive, serial port, and
parallel port. You can also use them to test some external
devices.
Also, if you cannot determine whether a problem is caused
by the hardware or by the software, you can run the
diagnostic programs to confirm that the hardware is
working properly.
Note
When you run the diagnostic programs, a single
problem might cause several error messages. When
this occurs, work to correct the cause of the first error
message. After the cause of the first error message is
corrected, the other error messages might not occur
the next time you run the test.
Running diagnostic programs
While you are running the diagnostic programs, F1
displays Help information. Pressing F1 from within a help
screen provides a online documentation from which you
can select different categories. Pressing Esc exits Help
and returns to where you left off.
Important
If you run the diagnostic programs with either no
mouse or a USB mouse attached to your server, you
will not be able to navigate between test categories
using the Next Cat and Prev Cat buttons. All other
functions provided by mouse-selectable buttons are
also available using the function keys.
You can test the USB keyboard using the regular
keyboard test. The regular mouse test cannot test a
USB mouse. Also, you can run the USB hub test only
if there are no USB devices attached.
10 xSeries 240 HMM

Notes
1. To run the diagnostic programs, you must start
the server with the highest level password that is
set. That is, if an administrator password is set,
you must enter the administrator password, not
the power-on password, to run the diagnostic
programs.
2. If the server stops during testing and you cannot
continue, restart the server and try running the
diagnostic programs again. If the problem
persists, go to “Undetermined problems”on
page 210.
3. If the diagnostic tests do not find a problem but
the problem persists during normal operations,
see “Symptom-to-FRU index”on page 189 and
look for the problem symptom.
4. You might have to install a wrap connector on
your active parallel, serial, or Ethernet port to
obtain accurate test results for these ports. If
you do not have a wrap connector, contact your
IBM reseller or IBM marketing representative.
5. You might need a scratch diskette (that is, a
diskette which has no contents that you want to
save) to obtain accurate test results when testing
the diskette drive.
6. The keyboard and mouse (pointing device) tests
assume that a keyboard and mouse are attached
to the server.
To start the diagnostic programs:
1. Turn on the server and watch the screen.
If the server is turned on already, shut down your
operating system and restart the server.
2. When the message F2 for Diagnostics appears,
press F2.
If a power-on password or administrator password is
set, the server prompts you for it. Type in the
appropriate password; then, press Enter.
3. The Diagnostics Programs screen appears.
4. Select either Extended or Basic from the top of the
screen.
5. Select the test you want to run from the list that
appears; then, follow the instructions on the screen.
When the tests have completed, you can view the
Test Log by selecting Utility from the top of the
screen.
Also, you can view server configuration information
(such as system configuration, memory contents,
interrupt request (IRQ) use, direct memory access
(DMA) use, device drivers, and so on) by selecting
Hardware Info from the top of the screen.
xSeries 240 11

If the hardware checks out OK but the problem persists
during normal server operations, a software error might be
the cause. If you suspect a software problem, refer to the
information that comes with the software package.
Viewing the test log
If you are already running the diagnostic programs,
continue with step 4 in this procedure.
Notes
1. The test log will not contain any information until
after the diagnostic program has run.
2. The test log is maintained in memory while the
server is powered on. Turning off the power
clears the test log.
To view the Test Log:
1. Turn on the server and watch the screen.
If the server is turned on already, shut down your
operating system and restart the server.
2. When the message F2 for Diagnostics appears,
press F2.
If a power-on password or administrator password is
set, the server prompts you for it. Type in the
appropriate password; then, press Enter.
3. The Diagnostic Programs screen appears.
4. Select Utility from the top of the screen.
5. Select View Test Log from the list that appears; then,
follow instructions on the screen.
Power-on self-test (POST)
When you turn on the server, it performs a series of tests
to check the operation of server components and some of
the options installed in the server. This series of tests is
called the power-on self-test or POST.
POST does the following:
Checks the operation of some basic system-board
operations
Checks the memory
Compares the current server configuration with the
stored server configuration information
Configures PCI adapters
Starts the video operation
Verifies that drives (such as the diskette, CD-ROM,
and hard disk drives) are connected properly
If you have a power-on password or administrator
password set, you must type the password and press
Enter, when prompted, before POST will continue.
While the memory is being tested, the amount of available
memory appears on the screen. These numbers advance
