The server diagnostic test programs can identify most
problems associated with major components of the server:
the system board, Ethernet controller, video controller,
RAM, diskette drive, serial port, parallel port, keyboard,
and mouse.
You can start the diagnostic test programs from the
Startup panel, when the message
Press F2 for
Diagnostics
appears. Test options let you batch groups of
tests, specify test parameters (for example, which memory
DIMM you want to test), and specify the number of passes
that you want to run (1 through 9999).
You can also view the server configuration information
from the Diagnostic Utility menu. For example, you can
view the interrupt request (IRQ) and direct memory access
(DMA) assignments, memory usage, device drivers, and so
on.
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 options. 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 before POST will continue.
While the memory is being tested, the amount of available
memory appears on the screen. These numbers advance
as the system progresses through POST and the final
number that appears on the screen represents the amount
of memory available. If POST finishes without detecting
any problems, a single beep sounds, the POST OK on the
front LED panel comes on, and the first screen of the
operating system or application program appears.
If POST detects a problem, an error message appears on
the screen. A single problem can cause several error
messages to appear. When this occurs, work to correct
the cause of the first error message. After the cause is
corrected, the other error messages probably will not
appear the next time you turn on the system.
