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

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.

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

Enhanced Diagnostics Diskette

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

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

Diagnostics Diskette

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.

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.)

8 Netfinity 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
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

12 Netfinity Server HMM

for a menu item. (Note that each menu item has
a Help screen. To view the Help screen, select
the menu item; then, press F1.)

c. When you have finished viewing and changing

settings, press Esc to return to the

Configuration overview

You play a key role in how the server allocates resources
to organize and interconnect hardware devices and
software programs. This allocation process is referred to
as

configuration.

server depend on the number and types of devices and
programs that you install.

The server has connectors for several types of adapters.
Because of this flexibility, you can choose from among
thousands of adapters and devices that comply with any of
the following standards:

 Peripheral Component Interconnect (PCI)
 Industry Standard Architecture (ISA)
 Small Computer System Interface (SCSI)
 Accelerated Graphics Port (AGP)

You can obtain a listing of products that are compatible
with the server, and related configuration information, by
accessing the following World Wide Web address:

http://www.ibm.com/pc/us/compat/

Jumpers and switches are used to define certain
configuration values on the system board, adapters, and
other devices. If you need to set jumpers or switches on
adapters, drives, or other devices, refer to the
documentation that comes with the devices for specific
information about the appropriate jumper and switch
settings.

In general, the greater the number and variety of hardware
devices and software programs that you install in the
server, the more you will have to interact with the server
and the devices to correctly configure the system.

The server comes with the following hardware
configuration utility programs:

 Configuration/Setup Utility program

With the Configuration/Setup Utility program, you can
configure system board functions, such as serial and
parallel port assignments; change interrupt request
settings, and change the startup sequence for drives
that you install. You can also use this utility program
to set passwords for starting the server and accessing
the Configuration/Setup Utility program.

 SCSISelect Utility

With the built-in SCSISelect Utility program, you can
configure the SCSI devices that you install in the
server. You can use SCSISelect to change default
values, resolve configuration conflicts, and perform a
low-level format on a SCSI hard disk drive.

Before installing a new device or program, read the
documentation that comes with it. Reading the instructions

The steps required to configure the

18 Netfinity Server HMM

helps you to determine the steps required for installation
and configuration. The following actions are typically, but
not always, required to configure the server.

1. Run the Configuration/Setup Utility program and
record the current configuration settings.

See “Configuration/Setup utility program” on page 21.

2. Set jumpers or switches on the server's system
board.

3. Set jumpers or switches on the device.
See the device installation instructions.

4. Install the device in the server.
Reserve ISA legacy resources for ISA adapters. See

“ISA legacy resources” on page 36.

5. Resolve configuration conflicts.
See “Configuration conflicts” on page 20.

6. Install software programs, including device drivers.
Refer to the information that comes with the IBM

ServerGuide package for more information.

IBM Netfinity 3000 - Type 8476

Configuration conflicts

The resources used by the server consist of IRQs, DMA,
I/O port addresses, and memory. This information is
useful when a resource configuration conflict occurs.

Conflicts in the configuration occur if:

 A device that you installed requires the same

resource as another device. (For example, a conflict
occurs when two adapters try to write to the same
address space.)

 A device resource is changed (for example, changing

jumper settings).

 A device function is changed (for example, assigning

COM1

to two serial ports).

 A software program is installed that requires the same

resource as a hardware device.

The steps required to resolve a configuration error are
determined by the number and variety of hardware devices
and software programs that you install. If a hardware
configuration error is detected, a
message appears after the server completes POST and
before the operating system is loaded. You can bypass
the error by pressing Esc while the error message is
displayed.

The Configuration/Setup Utility program configures only the
system hardware and interrupt requests. The program
does not consider the requirements of the operating
system or the application programs. For these reasons,
memory-address configuration conflicts might occur. You
can resolve some memory-address conflicts by changing
the address of the conflicting hardware option, or by
changing or moving the hardware. You might have to
resolve other memory-address conflicts by changing some
software parameters. See “Hardware configuration
conflicts” and “Software configuration conflicts” on
page 21, respectively, for additional information.

Hardware configuration conflicts

: Use the following information to help resolve hardware

configuration conflicts:

1. Run the Configuration/Setup Utility program to view
and change the resources that the system board
functions use. Record the current settings before
making any changes. (See “Configuration/Setup
utility program” on page 21 for instructions.)

2. Determine which adapter or device is causing the
conflict.

3. Change adapter jumpers or switches. Some devices
use jumpers and switches to define the system
resources that they need. If the settings are incorrect
or set to use a resource that cannot be shared, a

20 Netfinity Server HMM

conflict occurs, and the device will remain deactivated
by the configuration program.

4. Change system board jumpers or switches. Then,
refer to the system board diagram inside the server.

5. Remove the device or adapter. Some configurations
are not supported. If you must remove an adapter,
see “Installing or removing ISA and PCI adapters” on
page 62.

Software configuration conflicts

: The Configuration/Setup utility might change the

memory-address space used by some hardware options.
If this happens, the new memory-address space and IRQs
used by some hardware options might conflict with
addresses defined for use through application programs.

If a conflict exists, one or more of the following conditions
might exist:

 The system cannot load the operating system.
 The system does not work.
 An application program does not operate, or it returns

an error.

 Screen messages indicate that a memory-address

conflict exists.

Note

Start the Configuration/Setup Utility program to view
the addresses that are used by the system board
functions.

The best way to resolve memory-address conflicts is to
change the addresses that are used by the application
program or the device driver. You can use the
Configuration/Setup Utility program to view and change
addresses.

Configuration/Setup utility program

For most configurations, the server will operate using the
default system settings. You need to change the settings
only to resolve configuration conflicts or to enable or
change device functions.

When you want or need to change the default settings, the
Configuration/Setup Utility program provides a convenient
way to display and change the settings.

After you run and exit the Configuration/Setup Utility
program, configuration information is stored in electrically
erasable programmable read-only memory (EEPROM).
While the server is powered off, the configuration
information remains available for the next system startup.

Always run the Configuration/Setup Utility program if you
receive an error message instructing you to do so. If you
installed or removed SCSI devices, run the SCSISelect

IBM Netfinity 3000 - Type 8476

21

Utility program (see “SCSISelect utility program” on
page 49). Review the information that comes with the
option before making changes.

When you restart the server for the first time after working
with most options, a message appears, indicating that a
configuration change has occurred. You are then
prompted to enter the Configuration/Setup Utility program
to manually update the configuration settings or to confirm
and save the settings that were automatically updated by
the system programs.

After you change an option and restart the server, the
following screen might appear.

POST Startup Error(s)

The following error(s) were detected when the system was

started:

162 Configuration Change Has Occurred

Select one of the following:

Continue
Exit Setup

Note

Depending on the configuration changes that
occurred, the error message that you see might be
different from the one shown here.

If the preceding screen appears, select Continue until you
reach the Configuration/Setup Utility program menu; then,
go to “Configuration/Setup utility program menus” on
page 24.

If the preceding screen does not appear, use the following
procedures to access the Configuration/Setup Utility
program menu.

To start the Configuration/Setup Utility program:

1. Power-on the server and watch the screen.
If the server is already turned on, power-off the

server, wait a few seconds until all in-use lights go
off, and then power the server back on. (Do not use
Ctrl+Alt+Del to restart the server.)

2. When the message Press F1 to enter
Configuration/Setup appears, press F1. The
Configuration/Setup Utility program menu appears.
For information about the menus, see
“Configuration/Setup utility program menus” on
page 24.
