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
