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. 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
from the help information and return to where you left off, press Esc.
b. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again. If the problem remains,
replace the component that was being tested when the server stopped.
c. The keyboard and mouse (pointing device) tests assume that a keyboard
and mouse are attached to the server.
d. 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.
e. You can test the USB keyboard by using the regular keyboard test. The
regular mouse test can test a USB mouse. Also, you can run the USB
interface test only if there are no USB devices attached.
f. 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.
If the diagnostic programs do not detect any hardware errors but the problem
persists during normal server operations, a software error might be the cause. If
you suspect a software problem, see the information that comes with the software
package.
Viewing the test log
When the tests are completed, you can view the test log by selecting Utility from
the top of the screen and then selecting View Test Log .
Notes:
1. You can view the test log only while you are in the diagnostic programs. When
you exit the diagnostic programs, the test log is cleared (saved test logs are not
affected). To save the test log so that you can view it later, click
Save Log on
the diagnostic programs screen and specify a location and name for the saved
log file.
2. To save the test log to a diskette, you must use a diskette that you have
formatted yourself; this function does not work with preformatted diskettes. If the
diskette has sufficient space for the test log, the diskette may contain other
data.
Viewing the System Error log
You can also view the System Error log from the diagnostic programs. See the
instructions in “POST error logs” on page 28.
Diagnostic error message tables
For descriptions of the error messages that might appear when you run the
diagnostic programs, see “Diagnostic error codes” on page 130.
