General checkout
The server diagnostic programs are stored in upgradable
read-only memory (ROM) on the system board. These
programs are the primary method of testing the major
components of the server: the system board, Ethernet
controller, video controller, RAM, keyboard, mouse
(pointing device), diskette drive, serial port, and parallel
port. You can also use them to test some external
devices. See “Diagnostic programs” on page 11.
Also, if you cannot determine whether a problem is caused
by the hardware or by the software, you can run the
diagnostic programs to confirm that the hardware is
working properly.
When you run the diagnostic programs, a single problem
might cause several error messages. When this occurs,
work to correct the cause of the first error message. After
the cause of the first error message is corrected, the other
error messages might not occur the next time you run the
test.
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 suspect to be part of a shared
DASD cluster, all diagnostic tests can be run except
diagnostic tests which tests the storage unit (DASD
residing in the storage unit) or the storage adapter
attached to the storage unit.
8 Netfinity 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. If multiple error codes are displayed, diagnose
the first error code displayed.
3. If the computer hangs with a POST error, go to
the “Symptom-to-FRU index” on page 285.
4. If the computer hangs and no error is displayed,
go to “Undetermined problems” on page 325.
5. Power Supply problems, see “Symptom-to-FRU
index” on page 285.
6. Safety information, see “Safety information” on
page 340.
7. For intermittent problems, check the error log;
see, “Error logs” on page 31.

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
Netfinity 5500 M20 - Type 8662
11
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
as the server progresses through POST and the final
number that appears on the screen represents the total
amount of memory available. If POST finishes without
detecting any problems, a single beep sounds, the first
screen of the operating system or application program
appears, and the System POST Complete (OK) light is
illuminated on the information LED panel.
If POST detects a problem, more than one beep sounds
and an error message appears on the screen.
Note
A single problem might cause several error messages.
When this occurs, work to correct the cause of the first
error message. After the cause of the first error
message is corrected, the other error messages
usually will not occur the next time you run the test.
For a list of error codes and messages, see
“Symptom-to-FRU index” on page 285.
POST beep codes
POST generates beep codes to indicate successful
completion or the detection of a problem.
One beep indicates the successful completion of
POST.
More than one beep indicates that POST detected a
problem. For a list of error codes and messages, see
“Symptom-to-FRU index” on page 285.
Error messages - descriptions
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
trained service personnel.
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:
POST error messages occur during startup when POST
finds a problem with the hardware or detects a change in
the hardware configuration. For a list of error codes and
messages, see “Symptom-to-FRU index” on page 285.
Diagnostic error messages:
Diagnostic error messages occur when a test finds a
problem with the server hardware. These error messages
are alphanumeric and they are saved temporarily in the
Test Log and logged in the System Error Log when
diagnostics are run. For a list of error codes and
messages, see “Symptom-to-FRU index” on page 285.
Software-generated error messages:
These messages occur if a problem or conflict is found by
an application program, the operating system, or both.
Messages are generally text messages, but they also can
be numeric. For information about these error messages,
refer to the documentation that comes with the software.
System error log
The System Error Log contains all error and warning
messages issued during POST and all system status
messages from the Netfinity Advanced System
Management Processor. See “System error log” on
page 31 for information about how to view the System
Error Log.
Option diskettes
An optional device or adapter might come with an Option
Diskette. Option Diskettes usually contain option-specific
diagnostic test programs or configuration files.
If the optional device or adapter comes with an Option
Diskette, follow the instructions that come with the option.
Different instructions apply depending on whether the
Option Diskette is startable or not.

Running diagnostic programs
Note
The allowed keyboard and mouse configurations for
running diagnostics are as follows:
1. PS/2 keyboard, PS/2 mouse
2. PS/2 keyboard, no mouse -- With no mouse, you
will not be able to navigate between test
categories directly using the [Next Cat] and [Prev
Cat] buttons. All other mouse-selectable buttons
are also available via function keys.
3. USB keyboard, no mouse -- With no mouse, you
will not be able to navigate between test
categories directly using the [Next Cat] and [Prev
Cat] buttons. All other mouse-selectable buttons
are also available via function keys.
4. USB keyboard, USB mouse -- The USB mouse
will not be used by diagnostics; so, with no
mouse, you will not be able to navigate between
test categories directly using the [Next Cat] and
[Prev Cat] buttons. All other mouse-selectable
buttons are also available via function keys.
You can test the USB keyboard using the regular
keyboard test but you will not be able to test the USB
mouse. Also, you can only run the USB Hub test if
there are no USB devices attached.
While you are running the diagnostic programs, F1
displays Help information. Pressing F1 from within a help
screen provides a help index from which you can select
different categories. Pressing Esc exits Help and returns
to where you left off.
Also, be sure to check the Test Log for further diagnostic
error information.

Notes
1. To run the diagnostic programs, you must start
the server with the highest level password.
That is, if you enter the power-on password and
an administrator password is set, you cannot run
the programs. You can only view the error
messages in the Test Log.
You must enter the administrator password to run
the diagnostic programs.
2. If the server stops during testing and you cannot
continue, restart the server and try running the
diagnostic programs again.
3. You might have to install a wrap connector on
the active parallel, serial, or Ethernet port to
obtain accurate test results for these ports. If
you do not have a wrap connector, contact your
IBM reseller or IBM marketing representative.
4. You might need a scratch diskette (that is, a
diskette which has no contents that you want to
save) to obtain accurate test results when testing
the diskette drive.
5. The keyboard and mouse (pointing device) tests
assume that a keyboard and mouse are attached
to the server.
Tips on the diagnostic programs:
1. For system board tests, first remove all installed
adapters.
2. Hard drive surface analysis can be found on the
Utility menu.
3. Check the System Error Log for entries when memory
errors occur.
4. Universal serial bus testing notes:
The USB interface test will fail with a normal
keyboard and a USB device attached.
The USB interface test will abort with a USB
keyboard and USB mouse in use.
The system will disable USB during POST with a
standard keyboard attached.
5. When viewing a test, if it has dashes (-) through its
box, it is unable to run because the relevant device is
either not installed or is failing.

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 supports several types of adapters and SCSI
devices. Because of this flexibility, you can choose from
among many adapters and devices that comply with any of
the following standards:
Peripheral Component Interconnect (PCI)
Industry Standard Architecture (ISA)
Small Computer System Interface (SCSI)
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
With the built-in Configuration/Setup Utility program,
you can configure system board functions, such as
serial and parallel port assignments; change interrupt
request (IRQ) settings; and change the startup
sequence for drives that you install. You also can
use this utility program to set passwords for starting
up the server and accessing the Configuration/Setup
Utility program.
ServeRAID
You can use ServeRAID programs to define and
maintain the disk arrays. You can also use these
programs to configure SCSI devices (such as
hot-swap drives) that are attached to the ServeRAID
controller on the system board. Refer to “ServeRAID
system board controller” on page 66 for complete
instructions.
Before installing a new device or program, read the
documentation that comes with it. Reading the instructions
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.
2. Set jumpers or switches on the server system board.
See “Changing jumper positions” on page 176 and
“System board jumpers” on page 280.
3. Set jumpers or switches on the device.
See the device installation instructions.
The steps required to configure the
20 Netfinity Server HMM
4. Install the device in the server.
See “Locations/Removals” on page 160.
If you install an ISA adapter that is not a Plug and
Play device, select the Plug and Play choice on the
main menu of the Configuration/Setup Utility program
to assign the ISA legacy resources. See “Plug and
Play” on page 31 for more information.
5. Install software programs.
See the installation instructions that come with the
software.
6. Resolve configuration conflicts.
See “Resolving configuration conflicts” on page 33.
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 (for example, defining diskette
types, and so on).
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 from the Configuration/Setup Utility
program, configuration information is stored in nonvolatile
random-access memory (NVRAM). While the server is off,
the configuration information remains available for the next
system startup.
Always run the Configuration/Setup Utility program if you
add, remove, or relocate any hardware option, or if you
receive an error message instructing you to do so. Review
this information and the information that comes with the
option before making changes.
Finally, should you ever need to restore the default
configuration, the default configuration can be loaded by
starting the system and then pressing the reset button four
times, waiting 15 seconds between each press. Once the
configuration has reset to the default, it must be saved in
Setup to be stored in CMOS.
To start the Configuration/Setup Utility program:
1. Turn on the server and watch the screen.
2. When the message Press F1 for
Configuration/Setup appears, press F1.
