xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide
Chapter 3. Diagnostics
This section 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 section,
see Appendix A, “Getting help and technical assistance,” on page 147 for more
information.
General checkout
Follow the checkout procedure for diagnosing hardware problems. Review the
following information before performing the checkout procedure:
v Read Appendix B, “Safety information,” on page 149.
v The server diagnostic programs are stored in electrically erasable programmable
read-only memory (EEPROM) on the system board that is shared with the BIOS
code. These programs provide the primary methods of testing the major
components of the server. If you are not sure whether a problem is caused by
the hardware or by the software, you can run the diagnostic programs (see
“Diagnostic programs, error codes and messages” on page 15) 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 no beep or more than one beep sounds, see
“Beep symptoms” on page 104 or “No-beep symptoms” on page 107.
4. If the server is suspended and a POST error code is displayed, see “POST
error codes” on page 107.
5. If the server is suspended and no error message is displayed, see “Error
symptoms” on page 121 and “Undetermined problems” on page 138.

3. Set all display controls to the middle position.
4. Turn on all external devices.
5. Turn on the server.
6. Record any beep codes that sound or POST error messages that are
displayed on the screen. If no beep or more than one beep sounds,
look up the error in “Beep symptoms” on page 104 or “No-beep
symptoms” on page 107; if an error is displayed, look up the first error
in “POST error codes” on page 107.
7. Check the operator information panel system-error LED; if it is on, see
“Light path diagnostics” on page 17.
8. Check the system-error log and the BMC log.
Note: The system-error log is available only with the Remote
Supervisor Adapter II SlimLine.
If an error was recorded by the server, see Chapter 6,
“Symptom-to-FRU index,” on page 103.
9. Start the diagnostic programs.
10. Check for the following responses:
v One beep
v Readable instructions or the main menu
003
DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in Chapter 6, “Symptom-to-FRU index,” on
page 103.
YES. Run the diagnostic programs (see “Diagnostic programs, error codes
and messages” on page 15).
If you receive an error, see Chapter 6, “Symptom-to-FRU index,” on page
103.

xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide
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 error logs”
on page 14).
The POST error log contains the three most recent error codes and messages
that the system has generated during POST.
The system-error log contains all the error messages that were issued during
POST.
Note: The system-error log is available only with the Remote Supervisor Adapter
II SlimLine.
v Diagnostic programs and error messages
The server diagnostic programs, stored in upgradable read-only memory (ROM)
on the system board, are the primary method of testing the major components of
the server (see “Diagnostic programs, error codes and messages” on page 15).
v ServerGuide error symptoms
ServerGuide™ error symptoms are described at “ServerGuide error symptoms”
on page 129.
v SCSI error messages
For information on SCSI errors, see “Small computer system interface messages”
on page 21 and “SCSI error codes” on page 130
v Light path diagnostics
The server has light-emitting diodes (LEDs) to help you identify problems with
server components. By following the light path, you can identify the type of
problem that occurred. The light path begins with the LEDs on the operator
information panel (see “Light path diagnostics” on page 17).
v Error symptom tables
These tables list problem symptoms, along with suggested steps to correct the
problems (see the “Error symptoms” on page 121).
Chapter 3. Diagnostics
13
POST error logs
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, and the first
screen of the operating system or application program appears.
If POST detects a problem, more than one beep sounds, an error message appears
on the screen, or both (see “Beep symptoms” on page 104 and “POST error codes”
on page 107).
Note: 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.
The POST error log contains the three most recent error codes and messages that
the system generated during POST.
The system-error log or the BMC log contains all messages that were issued during
POST and all system status messages from the service processor.
Note: The system-error log is available only with the Remote Supervisor Adapter II
SlimLine.
Viewing error logs from the Configuration/Setup Utility program
To view the POST error log, the system-error log, or the BMC log from the

Diagnostic programs, error codes and messages
The server diagnostic programs are stored in electrically erasable programmable
read-only memory (EEPROM) on the system board that is shared with the BIOS
code. These programs are the primary method of testing the major components of
your server.
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.
Error codes that might be displayed are listed at “Diagnostic error codes” on page
115.
Notes:
1. Depending on the server configuration, some of the error codes might not
appear when you run the diagnostic programs.
2. If diagnostic error codes appear that are not listed in the tables, make sure that
the server has the latest levels of BIOS, Remote Supervisor Adapter II SlimLine,
and ServeRAID™ code installed.
Diagnostic text message format
The diagnostic text message format is as follows:
result test_specific_string
where:
result
is one of the following results:

Starting the diagnostic programs
Complete the following steps to start the diagnostic programs:
1. Turn off the server and any peripheral devices.
2. Turn on all attached devices; then, turn on the server.
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 user password,
to run the diagnostic programs.
3. When the prompt F2 for Diagnostics appears, press F2.
4. Type the appropriate password; then, press Enter.
5. Select either Extended or Basic from the top of the screen.
6. 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. 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
from the help information and return to where you left off, press Esc.
b. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again. If the problem remains,
replace the component that was being tested when the server stopped.
c. The keyboard and mouse (pointing device) tests assume that a keyboard
and mouse are attached to the server.
d. If you run the diagnostic programs with either no mouse or a USB mouse
attached to the 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.
e. 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
interface test only if there are no USB devices attached.
f. 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.
If the diagnostic programs do not detect any hardware errors but the problem
persists during normal server operations, a software error might be the cause. If
you suspect a software problem, see the information that comes with the software
package.
Viewing the test log
When the tests are completed, you can view the test log by selecting Utility from
the top of the screen and then selecting View Test Log. 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 (saved test logs are
not affected). To save the test log to a file on a diskette or to the hard disk so that
you can view it later, click Save Log on the diagnostic programs screen and specify
a location and name for the saved log file.

Note: To save the test log to a diskette, you must use a diskette that you have
formatted yourself; this function does not work with preformatted diskettes. If
the diskette has sufficient space for the test log, the diskette may contain
other data.
Viewing the system-error log
You can also view the system-error log from the diagnostic programs. See the
instructions in “Viewing error logs from the diagnostic programs” on page 14.
Note: The system-error log on the xSeries 236 is available only with the Remote
Supervisor Adapter II SlimLine.
For descriptions of the error messages that might appear when you run the
diagnostic programs, see “Diagnostic error codes” on page 115.
Light path diagnostics
The server’s light path diagnostics feature provides a path that can be followed in
distinct phases to help identify the source of an error. The lights are designed to be
followed in an orderly progression, depending on the error. The LEDs are viewed in
the following order:
1. Begin on the front panel.
2. Proceed to the light path diagnostics panel.
3. Check the system service label.
4. Look inside the server, if necessary.
Many errors are first indicated by the illumination of the system-error light in the
operator information panel on the front of the server (see “Server controls, LEDs,
and power” on page 3). If the system-error light is lit, one or more lights inside the
server might also be lit that can direct you to the source of the error.
The system information LED lights to alert you that there might be important
information recorded in the system-error log.
Complete the following steps to view the LEDs.
Note: Read Appendix B, “Safety information,” on page 149 and “Installation
guidelines” on page 27.
1. Check the system-error LED on the operator information panel on the front of
the server. A lit system-error LED indicates that a problem exists.
Note: Read “Working inside the server with the power on” on page 28 before
removing the left-side cover while the server is connected to a power
source.
2. Check the light path diagnostics panel by removing the left-side cover. These
LEDs indicate the type of error that has occurred and are described in more
detail at “Light path diagnostic errors” on page 113.

3. Once you know the general type of error and the general location of the
component involved, the next step is to check the system service label on the
outside of the server.
This label gives an overview of internal components that correspond to many of
the LEDs on the light path diagnostics panel and can help to view lit LEDs
inside the server.
Note: Some of the LEDs on the light path diagnostics panel will not have a
corresponding LED lit on the system board. For example:
v LEDs for the power supplies, fans, and hard disk drives are located on
or near the individual component.
v Some error conditions are corrected by taking an action not related to
one particular component; see step 5.
4. If the lit LED on the light path diagnostics panel refers to a specific internal
component as indicated in step 3, look on the system board for lit error LEDs
(see “System-board LEDs” on page 99). For example, a microprocessor error
will light the LED next to the failing microprocessor.
The error LEDs on the system board will only be lit when there is power to the
server. To view them, read “Working inside the server with the power on” on
page 28; then, remove the cover and look for any lit error LEDs.
If the lit LED on the light path diagnostics panel does not refer to a specific
internal component, continue with step 5.
5. Go to the table at “Light path diagnostic errors” on page 113 and find the entry
for the associated lit LED; then, replace the indicated component or take the
indicated action.
Notes:
v The system-error log and the BMC log might contain additional information that will be
helpful before replacing a component.
v If an LED on the light path diagnostics panel is lit and the system-error LED is not lit, there
is probably an LED problem. Run LED diagnostics.

download a BMC firmware update or a sensor data record/field replaceable unit
update. The firmware update utility program updates the BMC firmware or
SDR/FRU data only and does not affect any device drivers.
Go to http://www.ibm.com/support/ to download the utility program; then, copy the
flash.exe file to a firmware update diskette.
Note: To ensure proper server operation, be sure to update the server BMC
firmware code first before updating the BIOS code.
Chapter 3. Diagnostics
19
To update the firmware, use one of the following methods:
v If the Linux or Windows® operating-system update package is available from the
World Wide Web and you have obtained the applicable update package, follow
the instructions that come with the update package.
v If you are using a diskette, complete the following steps:
1. Insert the firmware update diskette into the USB diskette drive and restart the
server.
2. Follow the instructions on the screen.
Resetting the BMC firmware
If the BMC code in the server becomes damaged, the server might have difficulty
restarting (rebooting). If the server does not turn on and the heartbeat LED (H8) on
the system board is not on, you will need to reset the BMC firmware. (See
“System-board LEDs” on page 99 for the location of the heartbeat LED.)
Complete the following steps to reset the BMC firmware:
1. Read Appendix B, “Safety information,” on page 149 and “Handling
static-sensitive devices” on page 28.
2. Turn off the server and all attached devices.
3. Disconnect the power cord; then, disconnect all external cables.

If you receive a SCSI error message, see “SCSI error codes” on page 130.
Note: If your server does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
Recovering the BIOS code
If power to the server is interrupted while POST/BIOS code is being updated (flash
update), the server might not restart (reboot) correctly or might not display video (no
video). If this happens, you will need a BIOS recovery diskette.
To create this diskette, download the BIOS recovery disk image from
http://www.ibm.com/support/ and follow the directions in the image’s included
readme file.
Using the BIOS recovery diskette, complete the following steps to recover the BIOS
code:

Updating Remote Supervisor Adapter II SlimLine firmware
Information about updating the firmware of the Remote Supervisor Adapter II
SlimLine can be found in the Remote Supervisor Adapter II User’s Guide.
Power checkout
Power problems can be difficult to solve. For example, a short circuit can exist
anywhere on any of the power distribution buses. Usually a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
1. Turn off the server and disconnect all ac power cords.
2. Check for loose cables in the power subsystem. Also check for short circuits, for
example, if there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until the server is at the minimum configuration
required to start the server (see “Minimum operating requirements” on page
138).
4. Reconnect all ac power cords and turn on the server. If the server starts up
successfully, replace adapters and devices one at a time until the problem is
isolated. If the server does not start up from the minimal configuration, replace
FRUs of minimal configuration one at a time until the problem is isolated.
To use this method, it is important to know the minimum configuration required for a
system to start (see page 138). For specific problems, see “Power-supply LED
errors” on page 115.

Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the 10/100/1000 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the network, check the following
conditions:
v Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem remains, try a different cable.
If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,
you must use Category 5 or higher cabling.
v Determine whether the hub/switch supports auto-negotiation. If it does not, try
configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub/switch.
v Check the Ethernet controller LEDs on the rear of the server.
These LEDs indicate whether there is a problem with the connector, cable, or
hub/switch:
– The Ethernet transmit/receive activity LED, on the rear of the server, is lit
when the Ethernet controller sends or receives data over the Ethernet
Network. If the Ethernet transmit/receive activity LED is off, make sure that
the hub/switch and network are operating and that the correct device drivers
are installed.
– The Ethernet link status LED, on the rear of the server, is lit when the
Ethernet controller receives a LINK pulse from the hub/switch. If the LED is
off, there might be a defective connector or cable or a problem with the
hub/switch.
v Make sure that you are using the correct device drivers, which are supplied with
the server.
v Check for operating-system-specific causes for the problem.
v Make sure that the device drivers on the client and server are using the same
protocol.
v Test the Ethernet controller.
The way the Ethernet controller is tested depends on which operating system
you are using (see the Ethernet controller device driver readme files).
Ethernet controller troubleshooting chart
Use the following troubleshooting chart to find solutions to 10/100/1000 Mbps
Ethernet controller problems that have definite symptoms.
Description
FRU/action
The server stops
running when loading
device drivers.
The PCI BIOS interrupt settings are incorrect.
v Determine whether the interrupt (IRQ) setting that is assigned to the Ethernet controller
is also assigned to another device in the Configuration/Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not function well
when they share an interrupt with a dissimilar PCI device. Try changing the IRQ
assigned to the Ethernet controller or the other device. For example, for NetWare
Versions 3 and 4, it is recommended that disk controllers not share interrupts with LAN
controllers.
v Make sure that you are using the most recent device driver that is available from the
World Wide Web.
v Reseat or replace the adapter.

xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide
Chapter 4. Installing options
This chapter provides detailed instructions for installing hardware options in the
server.
Installation guidelines
Before you begin installing options in the server, read the following information:
v For a list of supported options for the server, go to
http://www.ibm.com/us/compat/.
v Read the safety information beginning on page v and the guidelines in “Handling
static-sensitive devices” on page 28. This information will help you work safely
with the server and options.
v Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v You do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, open or close a latch, and so on.
v Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.
v When you need to access the inside of the server, you might find it easier to lay
the server on its side.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has a drive or a filler panel and electromagnetic
compatibility (EMC) shield installed in it.
v There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the left-side cover before turning on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the left-side cover removed might damage server components.
v You have followed the cabling instructions that come with optional adapters.
v You have replaced a failed fan within 48 hours.
v You have replaced a hot-swap drive within 2 minutes of removal.
v You do not remove the air baffle while the server is running. Operating the server
without the air baffle might cause the microprocessor to overheat.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
microprocessor and heat sink.
© Copyright IBM Corp. 2004
27
Working inside the server with the power on
The server supports hot-swap devices and is designed to operate safely while it is
turned on and the cover is removed. Follow these guidelines when you work inside
a server that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts
before working inside the server; do not wear cuff links while you are working
inside the server.
v Do not allow your necktie or scarf to hang inside the server.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
v Remove items from your shirt pocket, such as pens and pencils, that could fall
into the server as you lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the server.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices, including the server.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the server for at least 2 seconds. This drains static electricity from
the package and from your body.
v Remove the device from its package and install it directly into the server without
setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.

switch or jumper settings on the adapter, follow the instructions that come with
the adapter.
v Avoid touching the components and gold-edge connectors on the adapter.
v You can install full-length adapters and non-hot-plug adapters in slots 4 and 5.
v A full-length adapter cannot be installed in slot 1 if the ServeRAID-7k option is
installed.
v The hot-plug slot (slot 6) supports full and half-length hot-plug and non-hot-plug
adapters. The hot-plug feature is operating system dependant. See the
documentation that comes with your operating system to see if it supports this
feature.
v The 32-bit PCI slot (slot 1) supports 5.0 V and 3.3 V PCI adapters, with the
exception that you cannot install a long adapter in slot 1 on servers with
ServeRAID-7k installed.
v The 64-bit PCI-X slots 4 through 6 support 3.3 V signaling PCI or PCI-X
adapters; they do not support 5.0 V signaling adapters.
v The PCI bus configuration is as follows:
– Non-hot-plug, 33 MHz 32-bit PCI slot 1 is on PCI bus A.
– Non-hot-plug, 64-bit PCI Express x4 slot 2 is on PCI bus B (independent of
slots 1, 3, 4, 5, and 6).
– Non-hot-plug, 64-bit PCI Express x4 slot 3 is on PCI bus C (independent of
slots 1, 2, 4, 5, and 6).
– Non-hot-plug, 100 MHz 64-bit PCI-X slots 4 and 5 and the integrated SCSI
controller with RAID capabilities are on PCI bus D.
– Hot-plug, 133 MHz 64-bit PCI-X slot 6 is on PCI bus F.
Note: If an optional ServeRAID controller is installed, it overrides the standard
functionality of the integrated SCSI controller with RAID capabilities. The
ServeRAID controller must be installed in its dedicated connector on the
system board.
v The system scans PCI and PCI-X slots 1 through 6 to assign system resources.
The system then starts (boots) the system devices in the following order, if you
have not changed the default boot precedence: integrated Ethernet controller,
integrated SCSI controller with RAID capabilities, and then PCI and PCI-X slots 1
through 6.
Note: To change the boot precedence for PCI and PCI-X devices, start the
Configuration/Setup Utility program and select Start Options from the
main menu. See the User’s Guide on the IBM xSeries Documentation CD

This index supports xSeries 236 servers.
Notes:
1. Check the configuration before you replace a CRU or FRU. Configuration
problems can cause false errors and symptoms.
2. For IBM devices not supported by this index, see the documentation for that
device.
3. Always start with “General checkout” on page 11.
The symptom-to-FRU index lists symptoms, errors, and the possible causes. The
most likely cause is listed first. Use this symptom-to-FRU index to help you decide
which FRUs to have available when servicing the server.
© Copyright IBM Corp. 2004
103
The first column of the two-column tables in this index lists error codes or
messages, and the last column lists one or more suggested actions or FRUs to
replace. Take the action (or replace the FRU) that is suggested first in the list, and
then try the server again to see whether the problem has been corrected.
Note: Try reseating a suspected component or reconnecting a cable before
replacing the component.
The POST BIOS code displays POST error codes and messages on the screen.

Beep symptoms are short tones or a series of short tones separated by pauses
(intervals without sound). See the examples in the following table.

Error symptoms
You can use the error symptom tables to find solutions to problems that have
definite symptoms.
Note: Some of the components in this section may not be supported on your
server model.
If you cannot find the problem in the error symptom tables, run the diagnostic
programs to test the server.
If you have just added new software or a new option and the server is not working,
complete the following steps before using the error symptom charts:
1. Remove the software or device that you just added.
2. Run the diagnostic tests to determine whether the server is running correctly.
3. Reinstall the new software or new device.
In the following tables, if the entry in the FRU/action column is a suggested action,
perform that action; if it is the name of a component, reseat the component and
replace it if necessary. The most likely cause of the symptom is listed first.

Problem determination tips
Because of the variety of hardware and software combinations that can be
encountered, use the following information to assist you in problem determination. If
possible, have this information available when requesting assistance from Service
Support and Engineering functions.
v Machine type and model
v Microprocessor or hard disk upgrades
v Failure symptom
– Do diagnostics fail?
– What message appears in the diagnostics log?
– What, when, where, single, or multiple systems?
– Is the failure repeatable?
– Has this configuration ever worked?
– If it has been working, what changes were made prior to it failing?
– Is this the original reported failure?
v Diagnostics version
– Type and version level
v Hardware configuration
– Print (print screen) configuration currently in use
– BIOS level
v Operating system software
– Type and version level
Note: To eliminate confusion, identical systems are considered identical only if
they:
v Are the exact machine type and models
v Have the same BIOS level
v Have the same adapters/attachments in the same locations
v Have the same address jumpers/terminators/cabling
v Have the same software versions and levels
v Have the same diagnostics code (version)
v Have the same configuration options set in the system
v Have the same setup for the operation system control files
Comparing the configuration and software set-up between “working” and
“non-working” systems will often lead to problem resolution.

Appendix B. Safety information
Note: The service procedures are designed to help you isolate problems. They are
written with the assumption that you have model-specific training on all
computers, or that are familiar with the computers, functions, terminology,
and service information provided in this manual.
The following section contains the safety information that you need to be familiar
with before servicing an IBM computer.
General safety
Follow these rules to ensure general safety:
v Observe good housekeeping in the area of the machines during and after
maintenance.
v When lifting any heavy object:
1. Ensure you can stand safely without slipping.
2. Distribute the weight of the object equally between your feet.
3. Use a slow lifting force. Never move suddenly or twist when you attempt to
lift.
4. Lift by standing or by pushing up with your leg muscles; this action removes
the strain from the muscles in your back. Do not attempt to lift any objects
that weigh more than 16 kg (35 lb) or objects that you think are too heavy for
you.
v Do not perform any action that causes hazards to the customer, or that makes
the equipment unsafe.
v Before you start the machine, ensure that other service representatives and the
customer’s personnel are not in a hazardous position.
v Place removed covers and other parts in a safe place, away from all personnel,
while you are servicing the machine.
v Keep your tool case away from walk areas so that other people will not trip over
it.
v Do not wear loose clothing that can be trapped in the moving parts of a machine.
Ensure that your sleeves are fastened or rolled up above your elbows. If your
hair is long, fasten it.
v Insert the ends of your necktie or scarf inside clothing or fasten it with a
nonconductive clip, approximately 8 centimeters (3 inches) from the end.
v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your
clothing.
Remember: Metal objects are good electrical conductors.
v Wear safety glasses when you are: hammering, drilling soldering, cutting wire,
attaching springs, using solvents, or working in any other conditions that might be
hazardous to your eyes.
v After service, reinstall all safety shields, guards, labels, and ground wires.
Replace any safety device that is worn or defective.
v Reinstall all covers correctly before returning the machine to the customer.

Many customers have, near their equipment, rubber floor mats that
contain small conductive fibers to decrease electrostatic discharges. Do
not use this type of mat to protect yourself from electrical shock.
Find the room emergency power-off (EPO) switch, disconnecting switch, or
electrical outlet. If an electrical accident occurs, you can then operate the switch
or unplug the power cord quickly.
Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
Before you start to work on the machine, unplug the power cord. If you cannot
unplug it, ask the customer to power-off the wall box that supplies power to the
machine and to lock the wall box in the off position.
If you need to work on a machine that has exposed electrical circuits, observe
the following precautions:
– Ensure that another person, familiar with the power-off controls, is near you.
Remember: Another person must be there to switch off the power, if
necessary.
– Use only one hand when working with powered-on electrical equipment; keep
the other hand in your pocket or behind your back.
Remember: There must be a complete circuit to cause electrical shock. By
observing the above rule, you may prevent a current from passing through
your body.
– When using testers, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you
from grounds such as metal floor strips and machine frames.
Observe the special safety precautions when you work with very high voltages;
these instructions are in the safety sections of maintenance information. Use
extreme care when measuring high voltages.
Regularly inspect and maintain your electrical hand tools for safe operational
condition.
xSeries 236 Type 8841: Hardware Maintenance Manual and Troubleshooting Guide
v Do not use worn or broken tools and testers.
v Never assume that power has been disconnected from a circuit. First, check that
it has been powered-off.
v Always look carefully for possible hazards in your work area. Examples of these
hazards are moist floors, nongrounded power extension cables, power surges,
and missing safety grounds.
v Do not touch live electrical circuits with the reflective surface of a plastic dental
mirror. The surface is conductive; such touching can cause personal injury and
machine damage.
v Do not service the following parts with the power on when they are removed from
their normal operating places in a machine:
– Power supply units
– Pumps
– Blowers and fans
– Motor generators
and similar units. (This practice ensures correct grounding of the units.)
v If an electrical accident occurs:
– Use caution; do not become a victim yourself.
– Switch off power.
– Send another person to get medical aid.
Safety inspection guide
The intent of this inspection guide is to assist you in identifying potentially unsafe
conditions on these products. Each machine, as it was designed and built, had
required safety items installed to protect users and service personnel from injury.
This guide addresses only those items. However, good judgment should be used to
identify potential safety hazards due to attachment of non-IBM features or options
not covered by this inspection guide.
If any unsafe conditions are present, you must determine how serious the apparent
hazard could be and whether you can continue without first correcting the problem.
Consider these conditions and the safety hazards they present:
v Electrical hazards, especially primary power (primary voltage on the frame can
cause serious or fatal electrical shock).
v Explosive hazards, such as a damaged CRT face or bulging capacitor
v Mechanical hazards, such as loose or missing hardware
The guide consists of a series of steps presented in a checklist. Begin the checks
with the power off, and the power cord disconnected.
Checklist:
1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Turn off the computer. Disconnect the power cord.
3. Check the power cord for:
a. A third-wire ground connector in good condition. Use a meter to measure
third-wire ground continuity for 0.1 ohm or less between the external ground
pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts
listings.
c. Insulation must not be frayed or worn.
4. Remove the cover.
Appendix B. Safety information
151
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the unit for any obvious unsafe conditions, such as metal filings,
contamination, water or other liquids, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Check that the power-supply cover fasteners (screws or rivets) have not been
removed or tampered with.
Handling electrostatic discharge-sensitive devices
Any computer part containing transistors or integrated circuits (ICs) should be
considered sensitive to electrostatic discharge (ESD). ESD damage can occur when
there is a difference in charge between objects. Protect against ESD damage by
equalizing the charge so that the server, the part, the work mat, and the person
handling the part are all at the same charge.
Notes:
1. Use product-specific ESD procedures when they exceed the requirements noted
here.
2. Make sure that the ESD-protective devices you use have been certified (ISO
9000) as fully effective.
When handling ESD-sensitive parts:
v Keep the parts in protective packages until they are inserted into the product.
v Avoid contact with other people.
v Wear a grounded wrist strap against your skin to eliminate static on your body.
v Prevent the part from touching your clothing. Most clothing is insulative and
retains a charge even when you are wearing a wrist strap.
v Use the black side of a grounded work mat to provide a static-free work surface.
The mat is especially useful when handling ESD-sensitive devices.
v Select a grounding system, such as those in the following list, to provide
protection that meets the specific service requirement.
Note: The use of a grounding system is desirable but not required to protect
against ESD damage.
– Attach the ESD ground clip to any frame ground, ground braid, or green-wire
ground.
– Use an ESD common ground or reference point when working on a
double-insulated or battery-operated system. You can use coax or
connector-outside shells on these systems.
– Use the round ground-prong of the ac plug on ac-operated computers.
Grounding requirements
Electrical grounding of the computer is required for operator safety and correct
system function. Proper grounding of the electrical outlet can be verified by a
certified electrician.
