Starting the diagnostic programs
You can press F1 while running the diagnostic programs to obtain Help information.
You also can press F1 from within a help screen to obtain online documentation from
which you can select different categories. To exit
Help and return to where you left off,
press Esc.
To start the diagnostic programs:
1. Turn on the server and watch the screen.
2. When the message F2 for Diagnostics appears, press F2.
3. Type in the appropriate password; then, press Enter.
4. Select either Extended or Basic from the top of the screen.
5. When the Diagnostic Programs screen appears, select the test you want to run
from the list that appears; then, follow the instructions on the screen.
Notes:
a. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again. If the problem persists, call for
service.
b. The keyboard and mouse (pointing device) tests assume that a keyboard and
mouse are attached to the server.
c. If you run the diagnostic programs with no 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.
d. You can test the USB keyboard by using the regular keyboard test. Also, you
can run the USB hub test only if there are no USB devices attached.
e. 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.
When the tests have completed, you can view the Test Log by selecting Utility from
the top of the screen.
If the tests do not detect a hardware problem 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
The test log will not contain any information until after the diagnostic program has run.
Note: If you already are running the diagnostic programs, begin with step 3 on page
96.
To view the test log:
1. Turn on the server and watch the screen.
If the server is on, 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 the appropriate password; then, press Enter.
