Chapter 3. Diagnostics
This chapter provides basic troubleshooting information to help solve some common
problems that might occur with the server.
If you cannot locate and correct the problem using the information in this chapter,
see Appendix A, “Getting help and technical assistance,” on page 105 for more
information.
General checkout
Follow the checkout procedure for diagnosing hardware problems. Review the
following information before performing the checkout procedure:
v Read the safety information beginning at “Safety information” on page 107.
v The diagnostic programs are on the IBM Enhanced Diagnostics CD. 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), serial ports, hard disk drives, and parallel port. You can also
use them to test some external devices. If you are not sure whether a problem is
caused by the hardware or by the software, you can use the diagnostic programs
to confirm that the hardware is working correctly.
v When you run the diagnostic programs, a single problem might cause several
error messages. If you receive several error messages, correct the cause of the
first error message. The other error messages might not occur the next time you
run the diagnostic programs.
v Before running the diagnostic programs, you must determine whether the failing
server is part of a shared hard disk drive cluster (two or more servers sharing
external storage devices). If you suspect that it is part of a cluster, you can run
all diagnostic programs except the ones that test the storage unit (that is, a hard
disk drive in the storage unit) or the storage adapter that is attached to the
storage unit. The failing server might be part of a cluster if any of the following
conditions is true:
– The customer identifies the failing server as part of a cluster.
– One or more external storage units are attached to the failing server and at
least one of the attached storage units is also attached to another server or
unidentifiable device.
– One or more servers are located near the failing server.
v Important:
1. For servers that are part of a shared hard disk drive cluster, run one test at a
time. Do not run any suite of tests, such as “quick” or “normal” tests, because
this could enable the hard disk drive diagnostic tests.
2. If more than one error code is displayed, correct the first error. The other
error codes might not occur the next time you run the diagnostic programs.
3. If the server is suspended and a POST error code is displayed, see “POST
error codes” on page 80.
4. If the server is suspended and no error message is displayed, see “Error
symptoms” on page 86 and “Undetermined problems” on page 97.
5. For information about power-supply problems, see “Power checkout” on page
22.
6. For intermittent problems, check the error log; see “Diagnostic programs and

Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes and error messages
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “Power-on self-test”
for more information.
v Diagnostic programs
The diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs are the primary method of testing the major components of the
server. See “Diagnostic programs and error messages” on page 16 for more
information.
v Error charts
These charts list problem symptoms and steps to correct the problem. See “Error
charts” on page 18 for more information.
v Symptom-to-FRU index
This index lists problem symptoms and steps to correct each problem. See
Chapter 7, “Symptom-to-FRU index,” on page 77 for more information.
Power-on self-test
When you turn on the server, the power on self-test (POST) performs a series of
tests to check the operation of system components and some of the installed
options.
If POST finishes without detecting any problems, the first window of the operating
system opens or an application program appears.
If POST detects a problem, more than one beep might sound, and an error
message appears on the screen.
Notes:
1. If you have a user password set, you must type the password and press Enter,
2. A single problem might cause several error messages. When this occurs, work
POST beep codes
POST generates beep codes to indicate successful completion or the detection of a
problem.
v One short beep indicates the successful completion of POST.
v More than one beep indicates that POST detected a problem. For more
If POST detects a problem (more than one beep sounds), an error message
appears on the screen. See “Beep symptoms” on page 78 and “POST error codes”

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 be resolved the
next time you run the test.
information, see “Beep symptoms” on page 78.
Chapter 3. Diagnostics 15
POST error messages
POST error messages can appear when a problem is detected during startup. For a
complete list of POST messages, see “POST error codes” on page 80.
Diagnostic programs and error messages
The system diagnostic programs are on the IBM Enhanced Diagnostics CD. These
programs are the primary method of testing the major components of the server.
An IBM Enhanced Diagnostics CD comes with the server. You can also download
the latest version of the diagnostic programs from http://www.ibm.com/pc/support/
(see “Downloading the diagnostic program” on page 17).
The IBM Enhanced Diagnostic programs isolate problems from the server hardware
and software. The programs run independently of the operating system and must
be run either from a CD or diskette.
Diagnostic error messages indicate that a problem exists; they are not intended to
be used to identify a failing part. Troubleshooting and servicing complex problems
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.
Text messages
Error codes that might be displayed are listed at “Diagnostic error codes” on page
83.
The diagnostic text message format is as follows:
result test_specific_string
where:
result is one of the following results:
Passed
This test was completed without any errors.
Failed
This test discovered an error.
User Aborted
You stopped the test before it was completed.
Not Applicable
You attempted to test a device that is not present in the server.
Aborted
The test could not proceed because of the server configuration.
Warning
A possible problem was reported during the test (for example, a
device that was to be tested is not installed).
test_specific_string

is an error code or other information about the error.
Downloading the diagnostic program
Complete the following steps to download the latest image of the IBM Enhanced
Diagnostics and create a startable Enhanced Diagnostics diskette or CD:
1. Go to http://www.ibm.com/pc/support/.
2. Download the diagnostics file for the server to a hard disk directory (not to a
diskette).
Note: If you intend to create a diagnostics CD, download the file with the
extension .iso.
3. Go to a DOS prompt, and change to the directory where the file was
downloaded.
4. If you are creating a diagnostics diskette, complete the following steps:
a. Insert a blank high-density diskette into the diskette drive.
b. Type filename a: (where filename is the name of the file you downloaded
from the Web), and press Enter.
The downloaded file is self-extracting when copied to the diskette. When the
copy is completed, you have a startable or bootable IBM Enhanced Diagnostics
diskette.
5. If you are creating a diagnostics CD, use a blank CD in conjunction with the
software you generally use to create a startable or bootable CD.
Starting the diagnostic programs and viewing the test log
The IBM Enhanced Diagnostic programs isolate problems from the server hardware
and software. The programs run independently of the operating system and must
be run either from a 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 test log records data about system failures and other pertinent information. The
following sections describe the diagnostic procedure for the diagnostics CD and the
diagnostics diskette.
Note: The system-error log is available on the xSeries 206 server only when the
server has an optional Remote Supervisor Adapter II.
Using the diagnostics CD
To start the IBM Enhanced Diagnostics using the CD, complete the following steps:
1. Turn off the server and any peripheral devices.
2. Turn on all attached devices; then, turn on the server.
3. When you see Press F1 For Configuration/Setup, press the F1 key.
4. When the Configuration/Setup Utility menu appears, select Start Options.
5. From the Start Options menu, select Startup Sequence.
6. Note the device that is selected as the first startup device. Later, you must
restore this setting.
7. Select CD-ROM as the first startup device.
8. Press Esc two times to return to the Configuration/Setup Utility menu.
9. Insert the IBM Enhanced Diagnostics CD in the CD-ROM drive.
10. Select Save & Exit Setup and follow the prompts. The diagnostics will load.
Follow the instructions on the screen to run the diagnostics.
Chapter 3. Diagnostics 17
11. When the tests are completed, view the test log by selecting Utility from the
top of the screen. You can save the test log to a file on a diskette or to the
hard disk.
Important: When you finish running the diagnostics and utilities, remove the
CD from the CD-ROM drive and turn off the server. You must
restore the first startup device to the original setting. Use steps 2
on page 17 through 8 on page 17 of this procedure to do this.
The test-log data is maintained only while the diagnostic programs are active.
When you exit from the diagnostic programs, the test log is cleared. Save the
test log to a file on a diskette or to the hard disk if you want to refer to it later.
Using the diagnostic diskette
Complete the following steps to start the IBM Enhanced Diagnostics using the
diagnostics diskette:
1. Turn off the server and any peripheral devices.
2. Insert the IBM Enhanced Diagnostics diskette into the external USB diskette
drive.
3. Turn on all attached devices; then, turn on the server.
4. Follow the instructions on the screen.
5. When the tests are completed, view the test log by selecting Utility from the top
of the screen. You can save the test log to a file on a diskette or to the hard
disk.
The test-log data is maintained only while the diagnostic programs are active.
When you exit from the diagnostic programs, the test log is cleared. Save the
test log to a file on a diskette or to the hard disk if you want to refer to it later.
6. When you have completed the diagnostics procedure, remove the diagnostic
diskette from the diskette drive before restarting the server.
If the hardware passes the Enhanced Diagnostics but the problem persists during
normal 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.
Diagnostic error message tables
For descriptions of the error messages that might appear when you run the
diagnostic programs, see “Diagnostic error codes” on page 83.
Note: Depending on the configuration, some of the error messages might not
appear when you run the diagnostic programs.
Error charts
Use the error charts to find solutions to problems that have definite symptoms (see
“Error symptoms” on page 86).
Small computer system interface (SCSI) messages (some models)
If the server has an Ultra320 SCSI adapter and you receive a SCSI error message,
see “SCSI error codes” on page 96.
Note: If the server does not have a SCSI hard disk drive, ignore any message that
indicates that the BIOS code is not installed.

Diagnostic LEDs
The system board has diagnostic LEDs for microprocessors, fans, and memory that
will help to locate the source of an error. Run the diagnostic programs (see “Starting
the diagnostic programs and viewing the test log” on page 17) to find out the cause
of the error.

Standby power
LED
DIMM 1 error LED
Each LED labeled as an “error” LED in the illustration above is lit to indicate a
problem with a specific component. After a problem is corrected, its LED will not be
lit the next time the server is restarted; if the problem remains, the LED will be lit
again.
Note: It is normal for the standby power LED to be lit when the server is connected
to ac power, regardless of whether the server is on or off. When the server is
connected to ac power and the LED is not lit, it indicates a power problem.
For information about correcting errors indicated by these LEDs, see “System board
LEDs” on page 85.
Updating BIOS code
You can update the BIOS code by using the diskette drive or by using a Linux or
Windows®update package (if available).
The most current level of BIOS code for the server is available at
http://www.ibm.com/pc/support/. You can update the BIOS code for the server
through one of the following methods:
v Downloading the latest BIOS code from the IBM Web site, creating an update
diskette, and using the diskette drive to install the BIOS code.
v Installing an update package for the Linux or Microsoft
system, if available.
