Diagnostics
15
Notes:
a. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again.
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 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.
d. 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 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 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
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.
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 in the appropriate password; then, press Enter.
3. When the Diagnostic Programs screen appears, select Utility from the top of the
screen.
4. Select View Test Log from the list that appears; then, follow the instructions on
the screen.
The system maintains the test-log data while the server is powered on. When you
turn off the power to the server, the test log is cleared.
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 115.
Attention: If diagnostic error messages appear that are not listed in the tables, make
sure that your server has the latest levels of BIOS, Advanced System.
