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 ports, hard drives,
and parallel port. You can also use them to test some external devices. See,
“Diagnostic tools overview” 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:
v The customer identifies the system as part of a cluster.
v 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.
v 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. If multiple error codes are displayed, diagnose the first error code displayed.
3. If the computer hangs with a POST error, go to “System Error logs” on page 14.
4. If the computer hangs and no error is displayed, “Diagnostic programs and
error messages” on page 14.
5. Power supply problems, “Power supply LED errors” on page 112.
6. For intermittent problems, check the error log; “Undetermined Problems” on
page 122.
1. IS THE SYSTEM PART OF A CLUSTER?
YES. Schedule maintenance with the customer. Shut down all systems related to
the cluster. Run storage test.
NO. Go to step 2.
2. THE SYSTEM IS NOT PART OF A CLUSTER
v Power-off the computer and all external devices.

Hardware Maintenance Manual: Type 8668
Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your server.
If you cannot locate and correct the problem using the information in this section,
refer to “Diagnostic tools overview” for more information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST beep code
descriptions” on page 13 for more information.
v Light Path Diagnostics
Your server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the Light Path Diagnostics feature
that is built into your server. By following the path of lights, you can quickly
identify the type of system error.
v Diagnostic programs and error messages
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 your server. See “Diagnostic programs and error
messages” on page 14 for more information.
v Customized support page
You can create a customized support page that is specific to your hardware,
complete with Frequently Asked Questions, Parts Information, Technical Hints
and Tips, and Downloadable files. In addition, you can choose to receive
electronic mail (e-mail) notifications whenever new information becomes
available about your registered products.

IBM HelpCenter
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.
If POST finishes without detecting any problems, a single beep sounds, the first
screen of your operating system or application program appears, and the System
POST Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message
appears on your screen. See “POST beep code descriptions” on page 13 and
“System Error logs” on page 14 for more information.
Notes:
1. 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.
2. A single problem might cause several error messages. When this occurs, work
to correct the cause of the first error message. After you correct the cause of the
first error message, the other error messages usually will not occur the next
time you run the test.
12 Hardware Maintenance Manual: Type 8668
POST beep code descriptions
Beep codes are sounded in a series of long and short beeps.
The possible types of beep codes that your server might emit include the
following:
No beeps
If no beep occurs after your server completes POST (that is, after the
system POST complete (OK) light on the operator information panel is
illuminated), call for service.
Continuous beep
Your startup (boot) microprocessor has failed, or your system board or
speaker subsystem might contain a failing component. If the system
continues through POST with no errors, call for service. If no video
appears, the startup processor has failed; replace the startup processor.
One short beep
One beep indicates that your server successfully completed POST. POST
detected no configuration or functional errors. One beep also occurs after
your server completes POST if you type an incorrect power-on password.
Two short beeps
POST encountered an error. The Configuration/Setup Utility program will
display additional information; follow the instructions that appear on the
screen. See “System Error logs” on page 14 for descriptions of the text
messages that might appear.
Three short beeps
A system memory error has occurred. This combination occurs only if the
video basic input/output system (BIOS) cannot display the error message.
Replace the failing memory module.
Repeating short beeps
The system board might contain a failing component, your keyboard might
be defective, or a key on the keyboard might be stuck. Ensure that:
v Nothing is resting on the keyboard and pressing a key.
v No key is stuck.
v The keyboard cable is connected correctly to the keyboard and to the
correct connector on the server.
Running the diagnostic tests can isolate the server component that failed,
but you must have your system serviced. If the error message remains, call
for service.
Note: If you just connected a new mouse or other pointing device, turn off
the server and disconnect that device. Wait at least 5 seconds; then,
turn on the server. If the error message goes away, replace the
device.
One long and one short beep
POST encountered an error on a video adapter. If you are using the
integrated video controller, call for service. If you are using an optional
video adapter, replace the failing video adapter.
One long and two short beeps
A video I/O adapter ROM is not readable, or the video subsystem is
defective. If you hear this beep combination twice, both the system board
and an optional video adapter have failed the test. This beep combination
might also indicate that the system board contains a failing component.
Diagnostics 13
One long and three short beeps
The system-board video subsystem has not detected a monitor connection
to the server. Ensure that the monitor is connected to the server. If the
problem persists, replace the monitor.
Two long and two short beeps
POST does not support the optional video adapter. This beep combination
occurs when you install a video adapter that is incompatible with your
server. Replace the optional video adapter with one that the server
supports, or use the integrated video controller.
System Error logs
To view the contents of the error logs, start the Configuration/Setup Utility
program; then, select Error Logs from the main menu.
The POST error log contains the three most recent error codes and messages that
the system generated during POST. The System Event/Error Log contains all error
messages issued during POST and all system status messages from the IBM
remote supervisor adapter, if installed.

If you receive a SCSI error message while using the SCSISelect Utility. Use the
following list to determine the possible cause of the error and what action to take.
Note: If your system does not have a hard disk drive, ignore any message that
indicates that the BIOS code is not installed.
v A failing SCSI device (adapter or drive)
v An improper SCSI configuration
v Duplicate SCSI IDs in the same SCSI chain
v An improperly installed SCSI terminator
v A defective SCSI terminator
v An improperly installed cable
v A defective cable
One or more of the following might be causing the problem.
Action:
Verify that:
v The external SCSI devices are turned on. External SCSI devices must be turned
on before the server.
v The cables for all external SCSI devices are connected correctly.
v The last device in each SCSI chain is terminated properly.
v The SCSI devices are configured correctly.
If the above items are correct, run the diagnostic programs to obtain additional
information about the failing device.
Diagnostic programs and error messages
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 your server.
14 Hardware Maintenance Manual: Type 8668
Diagnostic programs and error messages
Diagnostic 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 that are indicated by error messages should be performed by trained
service personnel.
Sometimes the first error to occur causes additional errors. In this case, the server
displays more than one error message. Always follow the suggested action
instructions for the first error message that appears.
The following sections contain the error codes that might appear in the detailed
test log and summary log when running the diagnostic programs.
The error code format is as follows:
fff-ttt-iii-date-cc-text message
where:
fff is the three-digit function code that indicates the function being tested
when the error occurred. For example, function code 089 is for the
microprocessor.
ttt is the three-digit failure code that indicates the exact test failure that was
encountered.
iii is the three-digit device ID.
date is the date that the diagnostic test was run and the error recorded.
cc is the check value that is used to verify the validity of the information.
text message
is the diagnostic message that indicates the reason for the problem.
Text messages
The diagnostic text message format is as follows:
Function Name: Result (test specific string)
where:
Function Name
is the name of the function being tested when the error occurred. This
corresponds to the function code (fff) given in the previous list.
Result can be one of the following:
Passed
Failed This result occurs when the diagnostic test discovers an error.
User Aborted
This result occurs when the diagnostic test completes without any
errors.
This result occurs when you stop the diagnostic test before it is
complete.
Not Applicable
This result occurs when you specify a diagnostic test for a device
that is not present.
Aborted
This result occurs when the test could not proceed because of the
system configuration.

Diagnostic programs and error messages
Warning
This result occurs when a possible problem is reported during the
diagnostic test, such as when a device that is to be tested is not
installed.
Test Specific String
This is additional information that you can use to analyze the problem.
Starting the diagnostic programs
You can press F1 while running the diagnostic programs to obtain Help
information. You also can press F1 from within a help screen to obtain online
documentation from which you can select different categories. To exit Help and
return to where you left off, press Esc.
To start the diagnostic programs:
1. Turn on the server and watch the screen.
Note: To run the diagnostic programs, you must start the server with the
highest level password that is set. That is, if an administrator password
is set, you must enter the administrator password, not the power-on
password, to run the diagnostic programs.
2. When the message F2 for Diagnostics appears, press F2.
3. Type the appropriate password; then, press Enter.
4. Select either Extended or Basic from the top of the screen.
5. When the Diagnostic Programs screen appears, select the test you want to run
from the list that appears; then, follow the instructions on the screen.
Notes:
a. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again.
b. The keyboard and mouse (pointing device) tests assume that a keyboard
and mouse are attached to the server.
c. If you run the diagnostic programs with no mouse attached to your server,
you will not be able to navigate between test categories using the Next Cat
and Prev Cat buttons. All other functions provided by mouse-selectable
buttons are also available using the function keys.
d. You can test the USB keyboard by using the regular keyboard test. The
regular mouse test can test a USB mouse. Also, you can run the USB hub
test only if there are no USB devices attached.
e. You can view server configuration information (such as system
configuration, memory contents, interrupt request (IRQ) use, direct memory
access (DMA) use, device drivers, and so on) by selecting Hardware Info
from the top of the screen.
When the tests have completed, you can view the Test Log by selecting Utility
from the top of the screen.
If the tests do not detect a hardware problem but the problem persists during
typical server operations, a software error might be the cause. If you suspect a
software problem, refer to the information that comes with the software package.

Recovering BIOS
Recovering BIOS code
If the BIOS code has become damaged, such as from a power failure during a flash
update, you can recover the BIOS using the recovery boot block and a BIOS flash
diskette.
Note: You can obtain a BIOS flash diskette from one of the following sources:
v Use the ServerGuide program to make a BIOS flash diskette.
v Download a BIOS flash diskette from the World Wide Web. Go to
http://www.ibm.com/pc/support, select IBM Server Support, and make
the selections for your server.
v Contact your IBM service representative.
The flash memory of your server contains a protected area that cannot be
overwritten. The recovery boot block is a section of code in this protected area that
enables the server to start up and to read a flash diskette. The flash utility recovers
the system BIOS code from the BIOS recovery files on the diskette.
To recover the BIOS:
Note: Default to pins 1 and 2 and is highlighted.
1. Turn off the server and peripheral devices and disconnect all external cables
and power cords; then, remove the cover.
2. Locate the boot block jumper block (J16) on the system board.
3. Move jumper to pins 2 and 3 to enable BIOS back-up page.
4. Insert the BIOS flash diskette into the diskette drive.
5. Restart the server.
6. The system begins the power-on self-test (POST). Select 1 - Update
POST/BIOS from the menu that contains various flash (update) options.

7. When you are asked if you would like to move the current POST/BIOS image
to the backup ROM location, type N.
Attention: Typing Y will copy the corrupted BIOS into the secondary page.
8. When you are asked if you would like to save the current code to a diskette,
select N.
9. You will be asked to choose which language you wish to use. Select your
language (0-7) and press Enter to accept your choice. You will be prompted to
remove the diskette and press Enter to restart the system. Remove the flash
diskette from the diskette drive.
Attention: Do not press Enter to reboot the system at this time.
10. power-off the server.
11. Move jumper J16 back to pins 1 and 2 to return to normal startup mode.
12. Restart the server. The system should start up normally.
Identifying problems using status LEDs
If the System Error light in the operator information panel on the front of the
server is on, one or more LEDs inside the server may be on. Use the Light Path
Diagnostics feature to identify the type of error that occurred. See “Diagnostic tools
overview” on page 11.
Recovering BIOS
You can use the Light Path Diagnostics feature built into your server to quickly
identify the type of system error that occurred. Your server is designed so that any
LEDs that are illuminated remain illuminated when the server shuts down as long
as the ac power source is good and the power supplies can supply +5 V dc current
to the server. This feature helps you isolate the problem if an error causes the
server to shut down. See “Diagnostic tools overview” on page 11.
Power-Supply LEDs
The ac and dc power LEDs on the power supply provide status information about
the power supply.
