IBM Netfinity 3500 - Type 8644 3

General Checkout
This general checkout procedure is for Netfinity 3500 -
Type 8644 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.
Notes
1. 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.
2. If multiple error codes are displayed, diagnose
the first error code displayed.
3. If the server hangs with a POST error, go to
“Symptom-to-FRU Index” on page 105.
4. If the server hangs and no error is displayed, go
to “Undetermined Problems” on page 38.
5. If an installed device is not recognized by the
diagnostics program, that device might be
defective.
6. Blank screen, unreadable screen, or other
unusual response occurs, go to
“Symptom-to-FRU Index” on page 105.
7. Power supply problems, see “Power Supply” on
page 39.
001
– Power-off the server and all external devices.
– Check all cables and power cords.
– Set all display controls to the middle position.
– Start the diagnostic programs, if necessary see “Running
the Diagnostic Test Programs” on page 9.
– Check for the following responses:
1. One or two beeps (depending on the diagnostics
version level).
(Step 001 continues)
4IBM Netfinity Servers HMM

001 (continued)
2. Readable instructions or the Main Menu.
DID YOU RECEIVE THE CORRECT RESPONSES?
Yes No
002
Go to the “Symptom-to-FRU Index” on page 105.
003
ARE ALL INSTALLED DEVICES IN THE SERVER
HIGHLIGHTED ON THE MODULE TEST MENU OR
HARDWARE CONFIGURATION REPORT?
Yes No
004
The missing device may be defective.
005
Run the Advanced Diagnostics test. If necessary, refer to
“Diagnostics.”
If you receive an error, go to “Symptom-to-FRU
Index” on page 105.
If the test stops and you cannot continue, replace the
last device tested.
Diagnostics
Server problems can be caused by the hardware, the
software, or a user error. An example of a user error is
pressing the wrong key on the keyboard.
Notes
Some hardware and software errors are caused
by configuration conflicts. For information on
handling these situations, see “Resolving
Configuration Conflicts” on page 41.
When running the diagnostic test programs, a
single problem can cause several error
messages to occur. When this happens, work to
correct the cause of the first error message.
After the cause is corrected, the other error
messages probably will not occur the next time
that you run the tests.
If the hardware is OK and you have not made an error,
you might have a software problem. If you suspect that
you have a software problem, refer to the information that
comes with that software package.
The following tools are available to help identify and
resolve hardware-related problems:

Diagnostic Test Programs
The server diagnostic test programs are stored on the IBM
Enhanced Diagnostics CD-ROM that comes with the
server. These programs are the primary method of testing
the system board, memory, and other standard features of
the Netfinity 3500 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 is installed on the hard
disk. The programs run independently of the operating
system, and
must be run either from CD or diskette .
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.
An IBM Enhanced Diagnostic CD-ROM comes with the
server.
In addition to the server test programs, the IBM Enhanced
Diagnostics CD 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 CD also contains
additional diagnostic programs for non-IBM devices.
See “Running the Diagnostic Test Programs” on page 9
for information on running the diagnostic programs that
come with the server.
6IBM Netfinity Servers HMM

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 21.)
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.)
If you hear no beep at all during POST, see
“Symptom-to-FRU Index” on page 105.
IBM Netfinity 3500 - Type 8644 7

POST Beep Codes
POST also generates beep codes to indicate successful
completion or the detection of an error.
One beep and the startup of the operating system or
application program indicates successful completion
of POST.
More than one beep indicates that POST detected an
error.
Error Messages
Error messages indicate that a problem exists.
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 complete list of POST
beep codes, see “Symptom-to-FRU Index” on page 105.
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.
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.
Symptom-to-FRU Index
The Symptom-to-FRU Index lists beeps, errors, symptoms,
and the possible causes. The most likely cause is listed
first. Use the “Symptom-to-FRU Index” on page 105 to
help you decide which FRUs to have available when
servicing the computer.
8IBM Netfinity Servers HMM

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.
Running the Diagnostic Test Programs
Note
See “Diagnostic Test Programs” on page 6 for a
description of the diagnostic programs that come with
the server.
To start the IBM Enhanced Diagnostics using the CD
that comes with the server, do the following:
1. Power-off the server and any attached devices.
Note
Do not press Ctrl+Alt+Del.
2. Power-on all attached devices; then, power-on the
server.
3. Place the IBM Enhanced Diagnostic CD in the
CD-ROM drive.
4. Select Exit Setup and follow the prompts. The
diagnostics program will load. Follow the instructions
on the screen to run the diagnostics program.
Attention
1. When you finish running diagnostic and utility
programs, remove the CD from the CD-ROM
drive and turn off the server.
2. Do not discard this CD. Store it in a safe place
for later use.
Make a backup copy of the IBM Enhanced Diagnostics CD
information on a diskette. To do this:
1. Insert a blank, 3.5-inch diskette into diskette drive A.
2. Follow the previous instructions for starting the IBM
Enhanced Diagnostics CD.
3. Select the menu choice for making a backup diskette.
4. Follow the 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.
IBM Netfinity 3500 - Type 8644 9

2. Insert the IBM Enhanced Diagnostics backup diskette
into diskette drive A.
3. Power-on all attached devices; then, power-on 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.
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
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.)
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 11.)
10 IBM Netfinity Servers HMM

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 on page 10, 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.
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
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/Setup Utility program menu.
d. Before you exit from the program, select Save
Settings. When you exit from the
Configuration/Setup Utility program menu (see
step 5e on page 12), the operating system will
start automatically (unless there is an unresolved
problem with the startup device).
Attention:
If you did
not change any settings in the
Configuration/Setup Utility program, note the
following:
You will get an error message if you exit
from the Configuration/Setup Utility program
without selecting Save Settings. The
operating system will not start, but the
server will automatically restart. When the
server restarts, you will get a POST error
message, and then the Configuration/Setup
Utility program will again start automatically.
You will not get an error message if you
select Save Settings and then exit from the
Configuration/Setup Utility program. The
system will save all settings as they
currently appear in the Configuration/Setup
Utility program, and the operating system
will start (unless there is an unresolved
problem with the startup device).
