v Blue on a component indicates touch points, were 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 For a list of supported options for the server, go to http://www.ibm.com/servers/
eserver/serverproven/compat/us/
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 Each of the power-supply bays has a power supply or power-supply blank
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 server cover before turning on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the server cover removed might damage server components.
v Yo u have followed the cabling instructions that come with optional adapters.
v Yo u have replaced a failed fan within 48 hours.
v Yo u have replaced a hot-swap drive within 2 minutes of removal.
v Yo u 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.
.
Working inside the server with the power on
The server supports hot-plug, hot-add, and hot-swap devices and is designed to
operate safely while turned on with the cover removed. Follow these guidelines
when you work inside a server that is turned on:
v Avoid 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 or pencils) that could fall into
the server as you lean over it.

Handling static-sensitive devices
Attention: Static electricity can damage the server and other electronic devices.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following
precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Wear an electrostatic-discharge wrist strap, if one is available.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed printed 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 it down. 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.

2 5, 6, 7, and 8
v The server supports online-spare memory. This feature disables the failed
memory from the system configuration and activates an online-spare memory
pair of DIMMs to replace the failed active DIMM pair. Online-spare memory
reduces the amount of available memory. Before you can enable this feature, you
must install one additional pair of DIMMs. The online-spare memory DIMM pair
must be the same speed, type, and the same size, or larger, than the active
DIMM pair.
Enable online-spare memory through the Configuration/Setup Utility program.
The BIOS code assigns the online-spare memory DIMM pair according to your
DIMM configuration. See the User’s Guide on the IBM xSeries Documentation
CD for information about enabling online-spare memory. See Table 4 for the
online-spare memory DIMM connector assignments.

Installing a microprocessor
The following notes describe the type of microprocessor that the server supports
and other information that you must consider when installing a microprocessor:
v The server supports up to two microprocessors. With two microprocessors, the
server can operate as a symmetric multiprocessing (SMP) server. With SMP,
certain operating systems and application programs can distribute the processing
load between the microprocessors. If the server comes with one microprocessor,
you can install a second microprocessor.
v Yo u might have to update the BIOS code. Be sure to read the documentation
that comes with the microprocessor, so that you can determine whether you have
to update the BIOS code. You can download the latest level of BIOS code and
many other code updates for your server at http://www.ibm.com/support/.
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and other options, go to http://www.ibm.com/servers/eserver/
serverproven/compat/us/.
v To order additional microprocessor options, contact your IBM marketing
representative or authorized reseller.
v When you install an additional microprocessor in socket J23, you must also
install the voltage regulator module (VRM) that comes with the microprocessor in
VRM connector J72.
v The microprocessor speeds are automatically set for this server; therefore, you
do not have to set any microprocessor frequency-selection jumpers or switches.
v If you have to replace a microprocessor, call for service.
v If the thermal-grease protective cover (for example, a plastic cap or tape liner) is
removed from the heat sink or fan sink, do not touch the thermal grease on the
bottom of the heat sink or fan sink or set down the heat sink or fan sink.
Note: Removing the heat sink or fan sink from the microprocessor destroys the
even distribution of the thermal grease and requires replacing the thermal
grease. Setting down the heat sink or fan sink onto any surface when the
thermal-grease protective cover is removed will contaminate the thermal grease.
If the thermal grease becomes contaminated with particles, it must be replaced.
For information about replacing contaminated thermal grease on the heat sink or
fan sink, contact IBM Services. For support phone numbers, go to
http://www.ibm.com/planetwide/, or in the U.S. and Canada, call 1-800-IBM-SERV

5
v Domain-name validation to negotiate compatible data-transfer speeds with each
device
v Cyclic redundancy checking (CRC), instead of the usual parity checking, to
improve data reliability
v An active terminator for SCSI bus termination
server comes with one SCSI cable, which connects the internal connector on
The
the system board to the standard hot-swap-drive backplane. If you plan to attach
external SCSI devices, you must order additional cables. To select and order the
correct cables for use with external devices, contact your IBM marketing
representative or authorized reseller.
SCSI cabling requirements
For information about the maximum length of SCSI cable, go to the American
National Standards Institute (ANSI) SCSI standards on the ANSI Web site at
http://www.ansi.org/. Adhering to these standards will help to ensure that the server
operates properly.
SCSI IDs
Each SCSI device that is connected to a SCSI controller must have a unique SCSI
ID. This ID enables the SCSI controller to identify the device and ensure that
different devices on the same SCSI channel do not attempt to transfer data
simultaneously. SCSI devices that are connected to different SCSI channels can
have duplicate SCSI IDs. Table 5 lists the SCSI IDs for the hard disk drives and
backplanes that are connected to one channel.

Chapter 5. 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,
see Appendix A, “Getting help and technical assistance,” on page 115 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 117.
v The server diagnostic programs are stored in upgradeable read-only memory
(ROM) on the system board. 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 and error messages” on page
64) 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.
Important:
v
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 logs” on page 63.
4. If the server is suspended and no error message is displayed, see “Error
symptoms” on page 91 and “Undetermined problems” on page 104.
5. For information about power-supply problems, see “Power checkout” on page
69.
6. For intermittent problems, check the error logs; see “Diagnostic programs and
error messages” on page 64.
© Copyright IBM Corp. 2005, 2007 61
Complete the following steps to perform the checkout procedure to identify system
problems.
001 IS THE SYSTEM PART OF A CLUSTER?
YES. Schedule maintenance for the system. Shut down all systems related
to the cluster. Run the storage test.
NO. Go to step 002.
002 IF THE SYSTEM IS NOT PART OF A CLUSTER:
1. Check the power supply LEDs, see “Power supply LEDs” on page 67.
2. Turn off the server and all external devices.
3. Check all internal and external devices for compatibility at
http://www.ibm.com/servers/eserver/serverproven/compat/us/.
4. Check all cables and power cords.
5. Set all display controls to the middle position.
6. Turn on all external devices.
7. Turn on the server.
8. Record any POST error messages that are displayed on the screen. If
an error is displayed, look up the first error in the “POST error codes”
on page 78.
9. Check the information LED panel system-error LED; if it is on, see
“Light path diagnostics LEDs” on page 83.
10. Check the system-error log and base-board management controller
(BMC) log. If the system recorded an error, see Chapter 6,
“Symptom-to-FRU index,” on page 73
11. Start the diagnostic programs.
12. Check for the following responses:
v One beep
v Readable instructions or the main menu
DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
003
NO. Find the failure symptom in Chapter 6, “Symptom-to-FRU index,” on
page 73
YES. Run the diagnostic programs. If necessary, see “Diagnostic programs
and error messages” on page 64.
If you receive an error, see Chapter 6, “Symptom-to-FRU index,” on page
73
If the diagnostic programs were completed successfully and you still
suspect a problem, see “Undetermined problems” on page 104.
Diagnostic tools overview
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes
The power-on self-test beep codes indicate the detection of a problem.
– One beep indicates successful completion of POST, with no errors.
– More than one beep indicates that POST detected a problem. Error messages
also appear during startup if POST detects a hardware-configuration problem.
See “POST error codes” on page 78 for a list of POST error codes.
Symptom-to-FRU index
v
62 xSeries 346 Types 8840 and 1880: Hardware Maintenance Manual and Troubleshooting Guide
POST error logs
This index list problem symptoms, error codes, and steps to correct the
problems. See Chapter 6, “Symptom-to-FRU index,” on page 73 for more
information.
v Diagnostic programs and error messages
The system diagnostic programs are provided in ROM. These programs test the
major components of your server. See “Diagnostic programs and error
messages” on page 64.
v Light path diagnostics
Use light path diagnostics to diagnose system errors quickly. See “Light path
diagnostics” on page 67 for more information.
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 your operating system or application program appears.
If POST detects a problem, more than one beep sounds, and an error message
appears on your screen. See “Beep symptoms” on page 74 and “POST error
codes” on page 78 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.
The POST error log contains the three most recent error codes and messages that
the system generated during POST. The system-error log or base-board
management controller (BMC) log contains all messages issued during POST and
all system status messages from the service processor.
You can view the contents of the system-error log and BMC log from the
Configuration/Setup Utility program or from the diagnostic programs.
Viewing error logs from the Configuration/Setup Utility program
To view error logs from the Configuration/Setup Utility program, start the
Configuration/Setup Utility program; then, select Error Logs from the main menu.
See Chapter 2, “Configuring the server,” on page 9 for more information.
Viewing error logs from diagnostic programs
To view error logs from diagnostic programs, complete the following steps:
1. Start the diagnostic programs.
2. Select Hardware Info from the top of the diagnostic programs screen.
3. Select System Error Log or BMC Log from the list that appears; then, follow
the instructions on the screen.

there is no logical drive defined (SCSI RAID systems) or the ServerGuide
System Partition is not present. Run the ServerGuide program, and ensure
that setup is complete.
Small computer system interface messages
If you receive a SCSI error message, see “SCSI error codes” on page 100.
Note: If your server does not have a hard disk drive, ignore any message that
indicates that the BIOS is not installed.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradeable read-only memory
(ROM) on the system board. 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
86.
Notes:
1. Depending on the server configuration, some of the error codes might not
appear when you run the diagnostic programs.
64 xSeries 346 Types 8840 and 1880: Hardware Maintenance Manual and Troubleshooting Guide
2. If diagnostic error codes appear that are not listed in the tables, make sure that
the server has the latest levels of BIOS, service processor, 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:

The test could not proceed because of the server configuration.
Warning
A hardware failure did not occur; the test could not be run
because of some other problem (for example, there might be a
configuration problem, the hardware is missing or is not being
recognized, or there is a hardware problem that is not related to
the hardware currently being tested).
test_specific_string
is an error code or other information about the error.
Starting the diagnostic programs
Complete the following steps 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.

interface test only if there are no USB devices attached.
f. Yo u 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.
the diagnostic programs do not detect any hardware errors but the problem
If
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. Yo u 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 or BMC log
You can also view the system-error log and BMC log from the diagnostic programs.
See the instructions in “Viewing error logs from diagnostic programs” on page 63.
Identifying problems using status LEDs
If the system-error LED on the front of the server is on, one or more LEDs inside
the server or on the power supply will be on. Your server has LEDs to help you
identify problems with some server components. These LEDs are part of the light
path diagnostics feature built into the server. By following the path of lights, you can
quickly identify the type of system error that occurred.
Your server is designed so that any LEDs that are lit remain lit when the server
shuts down as long as the ac power source is good and the power supply 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 “Diagnosing problems using light path
diagnostics” on page 68.
66 xSeries 346 Types 8840 and 1880: Hardware Maintenance Manual and Troubleshooting Guide
Power-on password override
Power-on password override. Changing the position of this switch bypasses the
power-on password check the next time the server is turned on and starts the
Configuration/Setup Utility program so that you can change or delete the power-on
password. You do not have to move the switch back to the default position after the
password is overridden.
Changing the position of this switch does not affect the administrator password.
Power supply LEDs
The ac and dc power LEDs on the power supply provide status information about
the power supply. The following illustration shows the location of the ac and dc
power LEDs.

failure occurs, the system-error LED is lit again.
Press the reset button to reset the server and run the power-on self-test (POST).
You might have to use a pen or the end of a straightened paper clip to press the
button.
The server is designed so that LEDs remain lit when the server is connected to an
ac power source but is not turned on, provided that the power supply is operating
correctly. This feature helps you to isolate the problem when the operating system
is shut down.
Diagnosing problems using light path diagnostics
LEDs in two locations on the server are available to help you diagnose problems
that might occur during installation. Use them in the following order:
1. Light path diagnostics panel – Look at this panel first. If a system error has
occurred, the system-error LED on the front of the light path diagnostics drawer
is lit. Slide the latch to the left on the front of the light path diagnostics drawer to
access the light path diagnostics panel. Note any LEDs that are lit, and then
close the drawer.
2. LEDs on the system board – To identify the component that is causing the
error, note the lit LED on or beside the component.
Light path diagnostics LEDs
For a complete list of the LEDs on the light path diagnostics panel, the problems
they indicate, and actions to solve the problems see “Light path diagnostics LEDs”
on page 83.
Recovering the BIOS code
If the BIOS code has become damaged, such as from a power failure during a flash
update, you can recover the BIOS code using the boot block jumper and a BIOS
recovery diskette.
Note: You can obtain a BIOS recovery diskette from one of the following sources:
v Use the ServerGuide Setup and Installation CD to make a BIOS recovery
diskette.
v Download a BIOS recovery diskette from the World Wide Web. Go to
http://www.ibm.com/support/, click IBM Server Support, and make the selections
for your server.
v Contact your IBM service representative.
flash memory of your server contains a protected area that cannot be
The
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 recovery diskette. The recovery utility
recovers the system BIOS code from the BIOS recovery files on the diskette.
Complete the following steps to recover the BIOS code:
1. Turn off the server, and disconnect all power cords and external cables.
2. Remove the server cover. See “Removing the cover” on page 16 for more
information.
3. Locate the flash boot block recovery jumper block (J60) on the system board.

5. Insert the BIOS recovery diskette into the diskette drive.
6. Reinstall the server cover; then, reconnect all power cords.
7. Restart the server. The system begins the power-on self test (POST).
8. Select 1 - Update POST/BIOS from the menu that contains various flash
update options.
9. When prompted as to whether you want to save the current code to a diskette,
press N.
10. When prompted to choose a language, select a language (from 0 to 7), and
press Enter to accept your choice.
11. Remove the BIOS recovery diskette from the diskette drive.
12. Turn off the server, and disconnect all power cords and external cables; then,
remove the server cover.
13. Remove the jumper from the flash boot block recovery jumper block, or move
it to pins 1 and 2 to return to normal startup mode.
14. Reconnect all external cables and power cords, and turn on the peripheral
devices; then, reinstall the server cover.
15. Restart the server. The server starts up normally.
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.
Chapter 5. Diagnostics 69
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
105).
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 105). For specific problems, see “Power-supply LED
errors” on page 100.
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 supports auto-negotiation. If it does not, try
configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub.
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:
– 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 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. If the LED is off, there
might be a defective connector or cable or a problem with the hub.
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 Ethernet link status
LED does not work.
The Ethernet
transmit/receive activity
LED does not work.
Data is incorrect or
sporadic.
The Ethernet controller
stopped working when
another adapter was
added to the server.
The Ethernet controller
stopped working without
apparent cause.
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.
v Make sure that the hub is turned on.
v Check all connections at the Ethernet controller and the hub.
v Use another port on the hub.
v If the hub does not support auto-negotiation, manually configure the Ethernet controller
to match the hub.
v If you manually configured the Duplex mode, make sure that you also manually
configure the speed.
v Reseat or replace the adapter.
v Make sure that you have installed the network device drivers.
v The network might be idle. Try sending data from this server.
v Make sure that you are using Category 5 or higher cabling when operating the server at
100 Mbps or at 1000 Mbps.
v Make sure that the cables do not run close to noise-inducing sources like fluorescent
lights.
v Make sure that the cable is connected to the Ethernet controller.
v Make sure that the PCI system BIOS code is current.
v Reseat the adapter.
v Determine whether the interrupt (IRQ) setting that is assigned to the Ethernet adapter is
also assigned to another device in the system. Use the Configuration/Setup Utility
program to determine whether this is the case.
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 that is
assigned to the Ethernet adapter or the other device.
v Reseat or replace the adapter.
v Run diagnostics for the Ethernet controller.
v Try a different connector on the hub.
v Reinstall the device drivers. See the operating-system documentation and the
ServerGuide information.
v Reseat or replace the adapter.
Ethernet controller messages
The integrated Ethernet controller might display messages from certain device
drivers. The latest available information concerning these messages is at the IBM
Support Web site at http://www.ibm.com/support/.
