General Checkout
This general checkout procedure is for Netfinity 3000 -
Type 8476 servers.
Attention
The drives in the system you are servicing might have
been rearranged or the drive startup sequence
changed. Be extremely careful during write operations
such as copying, saving, or formatting. Data or
programs can be overwritten if you select an incorrect
drive.
Diagnostic error messages appear when a test program
finds a problem with a hardware option. For the test
programs to properly determine if a test Passed , Failed , or
Aborted , the test programs check the error-return code at
test completion.
General error messages appear if a problem or conflict is
found by an application program, the operating system, or
both. For an explanation of these messages, refer to the
information supplied with that software package.
A failed system might be part of a shared DASD cluster
(two or more systems sharing the same external storage
device(s)). Prior to running diagnostics, verify that the
failing system is not part of a shared DASD cluster.
A system might be part of a cluster if:
The customer identifies the system as part of a
cluster.
One or more external storage units are attached to
the system and at least one of the attached storage
units is additionally attached to another system or
unidentifiable source.
One or more systems are located near the failing
system.
If the failing system is suspected to be part of a shared
DASD cluster, all diagnostic tests can be run except
diagnostic tests which test the storage unit (DASD residing
in the storage unit) or the storage adapter attached to the
storage unit.
4Netfinity Server HMM

Notes
1. For systems that are part of a shared DASD
cluster, run one test at a time in looped mode.
Do not run all tests in looped mode, as this could
enable the DASD diagnostic tests.
2. Before replacing any FRUs, ensure the latest
level of BIOS is installed on the system. A
down-level BIOS might cause false errors and
unnecessary replacement of the system board.
3. If multiple error codes are displayed, diagnose
the first error code displayed.
4. If the server hangs with a POST error, go to
“Symptom-to-FRU index” on page 160.
5. If the server hangs and no error is displayed, go
to “Undetermined problems” on page 198.
6. If an installed device is not recognized by the
diagnostics program, that device might be
defective.
7. If a blank screen, unreadable screen, or other
unusual response occurs, go to
“Symptom-to-FRU index” on page 160.
8. For power supply problems, see “Power supply”
on page 45.

Diagnostic test programs
IBM provides programs that you can run to diagnose
hardware and some software problems. Several utility
programs that provide helpful information about the server
are also included. One of these programs provides the
user interface for running these diagnostic and utility
programs.
The server diagnostic test programs are stored on the
IBM
Enhanced Diagnostics Diskette that comes with the server.
These programs are the primary method of testing the
system board, memory, and other standard features of the
Netfinity 3000 server. You can also use them to test some
external devices.
Also, if you cannot determine whether a problem is caused
by the hardware or by the software, you can run the test
programs to confirm that the hardware is working properly.
The IBM Enhanced Diagnostics programs will isolate the
server hardware from software that you have installed on
the hard disk. The programs run independently of the
operating system, and
must be run either from CD or
diskette . This method of testing is generally used when
other methods are not accessible or have not been
successful in isolating a problem suspected to be hardware
related.
The server diagnostic test programs can identify most
problems associated with major components of the server:
the system board, Ethernet controller, video adapter or
controller, random-access memory (RAM), diskette drive,
serial port, parallel port, keyboard, and mouse.
In addition to the server test programs, the
IBM Enhanced
Diagnostics Diskette contains utility programs that provide
information about the server hardware, including the
hardware configuration. This information might be useful
in helping to isolate problems related to the operating
system and device drivers.
The
IBM Enhanced Diagnostics Diskette also contains
additional diagnostic programs for non-IBM devices.
See “Running the diagnostic test programs” on page 11
for information on running the diagnostic programs that
come with the server.
IBM Netfinity 3000 - Type 8476 7

Power-on self-test (POST)
When you power-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 operation
Compares the current server configuration with the
stored server configuration information
Configures PCI adapters
Starts the video operation
Verifies that the drives (such as the diskette,
CD-ROM, and hard disk drives) are connected
properly
If Power-On Self-Test is set to [Enhanced], numbers that
show the amount of memory being tested appear in the
top-left corner of the screen until the total amount of
memory in the system is reached. Options for running a
quick POST or accessing the Configuration/Setup Utility
program appear in the lower-left corner of the screen.
Quick mode is the default mode of operation. To change
the mode to [Enhanced], select Start Options from the
Configuration/Setup Utility program menu and follow the
prompts on the screen.
Note
The amount of available memory shown might be
somewhat less than expected because of BIOS
shadowing in RAM.
If POST finishes without detecting any problems, the first
screen of the operating system or application program
appears (if you have not set a power-on password). If you
have set a power-on password, a password prompt
appears. You must enter the password before the first
screen of the operating system or application program will
appear. (For further information on using passwords, see
“System security” on page 27.)
If Power-On Status is set to [Enabled] and POST detects
a problem, you will hear multiple beeps or no beep. In
most cases, an error code appears in the top left corner of
the screen, and in some cases, a description of the error is
displayed beside the code. (Note that the screen will
sometimes display multiple error codes and descriptions.)
8Netfinity Server HMM

POST beep codes
If Power-On Status is set to [Enabled], POST also
generates beep codes to indicate successful completion or
the detection of an error.
The startup of the operating system or application
program indicates successful completion of POST.
More than one beep indicates that POST detected an
error.
For a list of beep codes, see “Symptom-to-FRU index” on
page 160.
Error messages
Error messages indicate that a problem exists; they are not
intended to be used to identify a failing part.
Troubleshooting and servicing of complex problems
indicated by error messages should be performed by a
trained service technician.
Hardware error messages that occur can be text, numeric,
or both. Messages generated by the software generally
are text messages, but they also can be numeric.
POST error messages and beep codes:
POST error messages and beep codes occur during
startup when POST finds a problem with the hardware or
detects a change in the hardware configuration. POST
error messages are 3-, 4-, 5-, 8-, or 12-character
alphanumeric messages and include brief explanations
(except I999XXXX errors).
For a list of error codes, see “Symptom-to-FRU index” on
page 160.
SCSI error messages
:These messages appear if a problem or conflict is
detected by the SCSI subsystem. Refer to the SCSI
documentation in the ServerGuide package that comes
with the server for information about these messages.
Diagnostic error messages
:Diagnostic error messages occur when a test finds a
problem with the server hardware. The messages present
text information that can be used to identify a failing part.
These error messages are alphanumeric. Follow the
instructions on the screen.
For a list of diagnostic codes, see “Symptom-to-FRU
index” on page 160.
IBM Netfinity 3000 - Type 8476 9

Software-generated error messages
:These messages occur if a problem or conflict is
found by an application program, the operating system, or
both. Error messages for operating-system and other
software problems are generally text messages, but they
also can be numeric messages. For information about
these software error messages, refer to the information
that comes with the operating system or application
program, or both.
Installing files from option diskettes
An optional device or adapter might come with a diskette.
Diskettes that are included in option packages usually
contain files that the system needs for recognizing and
activating the options. Until you install the necessary files,
the new device or adapter might cause error messages.
If the optional device or adapter comes with a diskette, you
might need to install some configuration (.CFG) files or
diagnostic files (.EXE or .COM) from the diskette to the
hard disk. Refer to the documentation that comes with the
option to see if you need to install files.
10 Netfinity Server HMM

Running the diagnostic test programs
Note
See “Diagnostic test programs” on page 7 for a
description of the diagnostic programs that come with
the server.
Attention
Do not discard the Enhanced Diagnostics Diskette.
Store it in a safe place for later use.
Make a backup copy of the IBM Enhanced Diagnostics
information on a diskette. To do this:
1. Insert a blank, 3.5-inch, formatted 2 MB diskette into
diskette drive A.
2. Use an operating-system command, such as the DOS
DISKCOPY command, to make a
complete backup
copy of the Enhanced Diagnostics Diskette. Using
the backup copy can prevent damage to the original
diskette. The operating-system documentation
provides information on backing up diskettes.
3. If applicable, follow any additional instructions on the
screen.
To start the IBM Enhanced Diagnostics using the
backup Diagnostic Diskette, do the following:
1. Power-off the server and any attached devices.
2. Insert the IBM Enhanced Diagnostics backup diskette
into diskette drive A.
3. Power-on all attached devices; then, power-on the
server.
4. Follow the instructions on the screen.
Power-on self-test (POST) messages
If you receive an error message during the power-on
self-test (POST), completing the steps outlined in this
section might enable you to resolve the problem.
Note.
If you have just added, removed, or changed the
location of a device and you receive an error
message, you must reconfigure the server. Follow the
procedure described in “Configuration/Setup utility
program menus” on page 24. If the procedure in
“Configuration/Setup utility program menus” on
page 24 does not eliminate the error message, then
proceed with the following instructions.
1. Write down all error code numbers and descriptions
that appear on the screen as you start the server.
(Note that a single problem can cause several error
messages to appear. When you correct the cause of
IBM Netfinity 3000 - Type 8476 11

the first error message, the other error messages
probably will not appear on the screen the next time
that you power-on the server.)
2. If you have set a power-on password and have the
password prompt set to On or Dual, a password
prompt appears. If you have set both power-on and
administrator passwords, you can type either of the
passwords at the password prompt. However, if you
think you might need to change any settings in the
Configuration/Setup Utility program, you must type the
administrator password at the password prompt. If
you type the power-on password, you will be able to
view the error codes and error code descriptions that
are displayed on the POST Startup Errors screen;
you will also be able to view limited information in the
Configuration/Setup Utility program. However, you
will not be able to change any settings.
3. In the case of most errors, the Configuration/Setup
Utility program starts automatically so that you can
attempt to identify and correct the problem. When the
Configuration/Setup Utility program starts, a screen
titled POST Startup Errors appears. (Note that the
POST Startup Errors screen does not appear
immediately. You must wait approximately one
minute.) If the POST Startup Errors screen does not
appear, proceed to step 6 on page 13.
4. At the POST Startup Errors screen, select Continue
if you want to access the Configuration/Setup Utility
program menu. Select Exit Setup if you want to exit
from the Configuration/Setup Utility program. (For
more information on exiting from the
Configuration/Setup Utility program, go to the
Attention: section that follows step 5d on page 13.)
To select an item, press the Up Arrow (↑) or Down
Arrow (↓) key to highlight the item; then, press Enter.
5. If you selected Continue in step 4, the
Configuration/Setup Utility program menu appears on
the screen. You will see a pointer next to any menu
items that indicate components that are
malfunctioning or that have been changed since the
last time you powered-on the server. If you did not
knowingly make a change to a flagged component,
that component is probably malfunctioning. If you
made a change, continue here. If you did not make a
change, go to the Attention: section that follows step
5d on page 13.
To use the Configuration/Setup Utility program, do the
following:
a. Select the menu item that is flagged (or that you
want to view) by pressing the Up Arrow (↑) or
Down Arrow (↓) key; then, press Enter.
b. A new menu specific to the item that you
selected appears. Press the Left Arrow (←) or
Right Arrow (→) key to toggle between choices
