Using passwords
The System Security choice appears only on the full Configuration/Setup Utility
menu. After you select this choice, you can implement two levels of password
protection: power-on password and administrator password. The administrator
password is available only if the optional IBM Remote Supervisor Adapter is
installed in your server.
Power-on password
After you set a power-on password, you can enable the Unattended Start mode.
This locks the keyboard and mouse but enables the operating system to start. The
keyboard and mouse remain locked until you type the correct password.
You can use any combination of up to seven characters (A–Z, a–z, and 0–9) for
your power-on password. Keep a record of your password in a secure place. When
a power-on password is set, POST is not completed until you type the password. If
you forget the power-on password, you can regain access to the server through one
of the following methods:
v If an administrator password is set, type the administrator password at the
power-on prompt. (If necessary, see “Administrator password” for details.) Start
the Configuration/Setup Utility program and change the power-on password.
v Remove the battery and then reinstall the battery (see “Replacing the battery” on
page 93).
v Change the position of the power-on password override switch (switch 6 on
switch block 1) as described below to bypass the power-on password check. You
can then start the Configuration/Setup Utility program and change the power-on
password.
Notes:
1. Before changing any switch settings or moving any jumpers, turn off the
server; then, disconnect all power cords and external cables.
2. Any system-board switch or jumper blocks that are not shown in the
illustrations in this book are reserved.
Power-on password override (switch 6)
Changing the position of this switch bypasses the power-on password
check the next time the server is powered on. You do not need to move
the switch back after the password is overridden. The default position is
Off. To bypass the power-on password check, move the switch to the
opposite position. Changing the position of this switch does not affect the
administrator password check if an administrator password is set.
Administrator password
Select this choice to set an administrator password. The administrator password
provides access to all choices on the Configuration/Setup Utility main menu. You
can set, change, or delete both the administrator and power-on passwords and
allow a power-on password to be changed by the user. You can use any
combination of up to seven characters (A–Z, a–z, and 0–9) for your administrator
password. Keep a record of your password in a secure place. The administrator
password is available only if the optional IBM Remote Supervisor Adapter is
installed in your server.
Attention: If an administrator password is set and then forgotten, it cannot be
overridden or removed. You must replace the system board.

Setup and configuration overview
When you use the ServerGuide Setup and Installation CD, you do not need setup
diskettes. You can use the CD to configure any supported IBM server model. The
ServerGuide program checks your system BIOS, service processors, and other
system hardware to determine if system updates are available. The setup program
provides a list of tasks that are required to set up your server model. On SCSI
RAID servers, you can run the SCSI RAID configuration program to create logical
drives.
Note: Features and functions can vary slightly with different versions of the
ServerGuide program.
When you start the ServerGuide Setup and Installation CD, the program performs
the following tasks:
v The ServerGuide program prompts you for your language, country, and keyboard
layout. (This information is stored and later passed to the operating system
installation program.)
v The ServerGuide program displays choices for running the configuration
programs. For example:
– The Express Configuration method runs the required programs for your
server, based on the hardware that is detected.
– The Custom Configuration method displays all programs that are available for
your server, and you decide which programs to run.
– The Replicated Configuration method provides the option of duplicating your
setup selections to other servers that are the same model.
Chapter 2. Configuration
19
v If you select the Custom Configuration method, the following features are
optional. If you select the Express Configuration method, some or all of these
features are run, depending on the hardware that is detected:
– The Set Date and Time feature is provided so that you do not have to use the
Configuration/Setup Utility program to access these settings.
– The Clear Hard Disks feature is provided so you can delete all partitions on all
hard disk drives. If the server has a SCSI RAID adapter installed, you can
select to restore the configuration on the SCSI RAID adapter to the factory
default settings.
– The ServerGuide program checks the server BIOS code and microcode
(firmware) levels for supported options and then checks the CD for a newer
level. The CD content might be newer than the BIOS code and firmware level.
The ServerGuide program can perform a flash update of the BIOS code and
supported microcode (firmware) options without using diskettes.
– The SCSI RAID configuration program starts, leading you through the entire
configuration process.
– The Performance Optimizer program easily tunes your server for your
environment.
– The ServerGuide program creates a System Partition on the default drive.
v The ServerGuide program displays a confirmation summary, so that you will
know when you have completed all the required tasks. Then, you are ready to
install your operating system.
Notes:
1. Plug and Play adapters are configured automatically. Non-Plug and Play
adapters or non-IBM adapters might require switch settings, additional device
drivers, and installation after the operating system is installed. See the
documentation that comes with the adapter.
2. Diagnostics for your server come in BIOS code or on a separate diagnostics
CD.
System Partition
The ServerGuide program creates a 50 MB System Partition on the default drive.
The System Partition contains server-specific utility programs such as service
processor disk operating system (DOS) utilities, system diagnostics, flash BIOS
updates, and other programs. Programs in the System Partition vary by server
model, and not all server models run utility programs from the System Partition. To
determine which ones do, start the ServerGuide Setup and Installation CD and view
the online overview.
After setup is complete, you can access programs in the System Partition by
restarting the server and pressing Alt+F1 when the prompt is displayed. The
System Partition menu displays the programs that are available on your server
model.
Typical operating system installation
You can use the ServerGuide program to shorten your installation time. The
ServerGuide program provides the device drivers that are required for your
hardware and for the operating system that you are installing. This section
describes a typical ServerGuide operating system installation.
Note: Features and functions can vary slightly with different versions of the
ServerGuide program.

xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
1. After you have completed the setup process, the operating system installation
program starts. (You will need your operating system CD to complete the
installation.)
2. The ServerGuide program stores information about the server model, service
processor, hard disk drive controllers, and network adapters. Then, the program
checks the CD for newer device drivers. This information is stored and then
passed to the operating system installation program.
3. With some operating system installations, you can create an operating system
replication diskette for setting up additional servers. This diskette contains the
Internet protocol (IP) address, server name, and other selections.
4. The ServerGuide program presents operating system partition options that are
based on your operating system selection and the installed hard disk drives.
5. If you are installing the operating system from diskette, the ServerGuide
program lists the diskettes that you must create and the optional diskettes that
you might want to create. The diskettes that you can create are the
device-driver diskettes for the installed adapters or controllers.
6. The ServerGuide program prompts you to insert your operating system CD and
restart the server. At this point, the installation program for the operating system
takes control to complete the installation.
Setting up or updating multiple servers
You can use the ServerGuide program to create diskettes that help you set up or
update multiple servers. You can modify information on the diskettes as you use
them to set up or update other servers.
Note: Availability and function can vary by server model and by the hardware that
is installed.
You can create a setup-replication diskette, which contains your hardware
configuration selections. Use this diskette to replicate selections to other servers
that are of the same model.
You can create a operating system replication diskette, which contains information
that you need to complete multiple installations. Not all operating systems support
operating system replication diskettes.
Installing your operating system without ServerGuide
If you have already configured the server hardware and you decide not to use the
ServerGuide program to install your operating system, complete the following steps
to download the latest operating system installation instructions from the IBM
Support Web page:
1. Go to http://www.ibm.com/pc/support/.
2. Under Browse, click Servers.
3. From the Family drop-down list, select your server model.

Using ServeRAID Manager
You can use the ServeRAID Manager program, provided on the IBM ServeRAID
Support CD, to:
v Configure a redundant array of independent disks (RAID)
v Restore a SCSI hard disk to factory-default settings, erasing all data
v View your RAID configuration and associated devices
v Monitor operation of your RAID controllers
The ServeRAID Manager program operates in two ways:
v Startable-CD mode
v As an installed software program
See the ServeRAID documentation on the IBM ServeRAID Support CD for
additional information about RAID technology and instructions for using ServeRAID
Manager. The Installation Guide for your server also contains instructions for using
ServeRAID Manager to configure your integrated SCSI controller with RAID
capabilities.
Notes:
1. The integrated SCSI controller with RAID capabilities in your server supports
only RAID level-1. Installing an optional ServeRAID-5i controller provides
additional RAID levels.
2. If you install a different type of RAID adapter in your server, use the
configuration method supplied with the RAID adapter to view or change SCSI
settings for attached devices.
Configuring the Gigabit Ethernet controller
The Ethernet controller is integrated on the system board. This controller provides
an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and
provides full duplex (FDX) capability, which enables simultaneous transmission and
reception of data on the Ethernet local area network (LAN). You do not need to set
any jumpers or configure the controller for your operating system before you use
the Ethernet controller. However, you must install a device driver to enable your
operating system to address the Ethernet controller. The device drivers are provided
on the ServerGuide Setup and Installation CD.
When you connect your server to the network, the Ethernet controller automatically
detects the data-transfer rate (10-Mbps, 100-Mbps, or 1000-Mbps) on the network
and then sets the controller to operate at the appropriate rate. In addition, if the
Ethernet ports that your server is connected to support auto-negotiation, the Gigabit
Ethernet controller will set the appropriate duplex state. That is, the Ethernet
controller will adjust to the network data rate, whether the data rate is standard
Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex
(HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and
full-duplex (FDX) modes at both speeds.
For updated information on configuring your Ethernet controller, go to the IBM
Support Web site at http://www.ibm.com/pc/support and navigate to the area for
your specific server type. From this area you can download documentation, the
most current device drivers for your server, and software that supports advanced
networking functions. After downloading, run the downloaded program launch.exe.
22

Updating the integrated system management firmware
To update the integrated system management (ISM) firmware for the integrated
system management processor (ISMP), download the Integrated System
Management Firmware Update Utility program for your server from the IBM Support
Web site at http://www.ibm.com/pc/support/. Then run the Integrated System
Management Firmware Update Utility program to create a diskette to use to update
the ISM firmware. This diskette updates the ISM firmware only and does not affect
any device drivers.
Complete the following steps to update the ISM firmware:
1. Turn off your server.
2. Insert the diskette into the diskette drive.
3. Turn on your server. If your server does not start from the diskette drive, use the
Configuration/Setup Utility program to configure the diskette drive as a startup
device. See “Using the Configuration/Setup Utility program” on page 11. Then,
start again at step 1
4. From the main menu, select Update System Management Firmware and
press Enter.

Chapter 3. 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 161 for more
information.
General checkout
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 the server: the system board, Ethernet controller, video
controller, RAM, keyboard, mouse (pointing device), diskette drive, serial ports, and
hard disk drives. You can also use the diagnostic programs to test some external
devices. See “Diagnostic programs and error messages” on page 29.
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 one or more external storage devices). Before you run 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 system is identified 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 also 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, you can run
all diagnostic tests except the diagnostic tests that 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, because this could enable
the DASD diagnostic tests.
2. If multiple error codes are displayed, diagnose the first error code that is
displayed.
3. If the computer stops with a POST error, go to “POST error codes” on page 141.
4. If the computer stops and no error is displayed, go to “Undetermined problems”
on page 151.
5. For power supply problems, see “Power-supply LED errors” on page 141.
6. For safety information, see “Safety information” on page 163.

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 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 125 and “POST error
codes” on page 141 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 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 from the Configuration/Setup
Utility program or from the diagnostic programs.
Viewing error logs from the Configuration/Setup Utility program
Start the Configuration/Setup Utility program; then, select Error Logs from the main
menu. See “Starting the Configuration/Setup Utility program” on page 12 for more
information.
Viewing error logs from the diagnostic programs

Small computer system interface messages
If you receive a SCSI error message, see “SCSI error codes” on page 147.
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.
The following sections contain the error codes that might appear in the detailed test
log and summary log when the diagnostic programs are run.
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
Chapter 3. Diagnostics
29
was encountered. (These codes are for trained service personnel;
see “Diagnostic error codes” on page 130).
iii
is the three-digit device ID. (These codes are for trained service
personnel; see “Diagnostic error codes” on page 130).
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) shown in the error code format in the
previous section.
Result
can be one of the following:
Passed
This result occurs when the diagnostic test
is completed without any errors.
Failed
This result occurs when the diagnostic test
discovers an error.
User Aborted
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, for example, because of the
system configuration.
Warning
This result occurs when a possible problem
is reported during the diagnostic test, such
as when a device driver is not found.
test specific string
is additional information that you can use to analyze the problem.
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.
30
xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
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. 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 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.
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.
Notes:
1. You can view the test log only while you are in the diagnostic programs. When
you exit the diagnostic programs, the test log is cleared (saved test logs are not
affected). To save the test log 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.
2. 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 “POST error logs” on page 28.
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 130.
Chapter 3. Diagnostics
31
Notes:
1. Depending on your server configuration, some of the error messages might not
appear when you run the diagnostic programs.
2. If diagnostic error messages appear that are not listed in the tables, make sure
that your server has the latest levels of BIOS, Advanced System Management
Processor, ServeRAID, and diagnostics microcode installed.
Identifying problems using status LEDs
If the system-error LED in the operator information panel on the front of the server
is on, one or more LEDs inside the server or on the power supplies 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 LEDs, you can quickly identify the type of system error that
occurred (see “Light Path Diagnostics” on page 34).
Your server is designed so that any LEDs that are illuminated remain illuminated
when the server shuts down, provided that 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 “System-board
LED locations” on page 49.
LEDs for Active PCI slots
Each Active™ (hot-plug) PCI slot has three LEDs associated with it: one power LED
and two attention LEDs. The following illustration shows the location of these LEDs.

Power LED
This LED is on when the hot-plug PCI slot has power. An adapter must not
be added to or removed from the PCI slot when the power LED is on.
When this LED is off, the hot-plug PCI slot has no power applied. An
adapter can be added to or removed from the PCI slot when the power
LED is off.
See your operating-system documentation to determine if your operating
system supports hot-plug PCI adapters and, if so, how to disable the
hot-plug PCI slot.
Attention LEDs
Each hot-plug PCI slot has an attention LED that is visible from the rear of
the server and one that can be seen from inside the server. These LEDs
have the same meaning; they are duplicated to be visible from outside or
inside the server.
An attention LED flashes approximately once per second when it is on. The
meaning of the attention LEDs is defined by your operating system. See
your operating-system documentation to determine if your operating system
supports hot-plug PCI adapters and, if so, what the attention LEDs indicate.
The following table describes the adapter power and attention LEDs.

Light Path Diagnostics
If the system error LED in the operator information panel on the front of the server
is on, one or more LEDs inside the server might be on. Use the Light Path
Diagnostics panel to quickly identify the type of error that occurred.
For LED locations, see “System-board LED locations” on page 49.
Your server is designed so that LEDs remain lit when the server shuts down,
provided that the power supplies are operating properly. This feature helps you to
isolate the problem even if an error causes the server to shut down.

diagnostics panel to see if any LEDs are lit. You can determine the cause of the
error and the action you should take by checking the table at “Diagnostic panel
system error LED” on page 128.
Notes:
1. Depending on your server model, these items might appear in a different
orientation on the LED panel.
2. The server supports a maximum of three PCI buses.
3. See the documentation that comes with the system-management software for
more information about the service processor.
Remind button
You can use the Remind button to place the front panel system-error LED into the
Remind mode. By pressing the button, you acknowledge the failure but indicate that
you will not take immediate action. If a new failure occurs, the system-error LED will
turn on again.
In the Remind mode, the system-error LED flashes every 2 seconds. The
system-error LED remains in the Remind mode until one of the following situations
occurs:
v All known problems are resolved
v The system is restarted
v A new problem occurs
You can use the Remind button to delay server maintenance until a later time. Also,
resetting the system-error LED enables the LED to react to another error. If the LED
is still on from the first error, it will not indicate additional errors. If you press the
Remind button (causing the LED to flash every 2 seconds) and another error
occurs, the LED will stop flashing and will instead be lit continuously to alert you to
the new error.

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 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/, click IBM Server Support, and make the
selections for your server.
v Contact your IBM service representative.
Complete the following steps to recover the BIOS code:
1. Turn off the server and disconnect all power cords and external cables; then,
remove the server cover (see “Removing the left-side cover” on page 51).
2. Locate the boot block recovery jumper (J28) on the system board. See
“System-board switches and jumpers” on page 47 for jumper location.
3. Remove the jumper from pins 1 and 2 of boot block recovery jumper and place
it on pins 2 and 3 of the boot block recovery jumper to enable BIOS recovery
mode.
4.
5.
6.
7.
Insert the BIOS flash diskette into the diskette drive.
Reconnect all power cords; then, reinstall the server cover.
Restart the server. The system begins the power-on self-test (POST).
Select 1 - Update POST/BIOS from the menu that contains various flash
(update) options.
8. When prompted as to whether you want to save the current code to a diskette,
press N.
9. When prompted to choose a language, select a language (from 0 to 7) and
press Enter to accept your choice.
10. Do not restart your server at this time.
11. Remove the BIOS flash diskette from the diskette drive.
12. Turn off the server and disconnect all power cords; then, remove the server
cover.
13. Remove the jumper from pins 2 and 3 of boot block recovery jumper (J28) and
place it on pins 1 and 2 of the boot block recovery jumper 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 and restart the server. The system
starts.
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.
36
xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
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
151).
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 151). For specific problems, see “Power-supply LED
errors” on page 141.
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 operator information panel and on the
rear of the server.
v
v
v
v
These LEDs indicate whether a problem exists with the connector, cable, or hub.
– The Ethernet transmit/receive activity LED, on the operator information panel,
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.
Make sure that you are using the correct device drivers which are supplied with
your server.
Check for operating-system-specific causes for the problem.
Make sure that the device drivers on the client and server are using the same
protocol.
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).

Chapter 4. Customer replaceable units
This chapter provides instructions for adding options to your server. Some
option-removal instructions are provided in case you need to remove one option to
install another.
Installation guidelines
Before you begin to install options in your server, read the following information:
v Become familiar with the safety and handling guidelines specified under
“Handling static-sensitive devices” on page 42 and read the safety statements in
“Safety information” on page 163.
v You do not need to turn off the server to install or replace hot-swap power
supplies, hot-swap drives, hot-swap fans, Active PCI (hot-plug) adapters, or
hot-plug Universal Serial Bus (USB) devices.
v The orange color on components and labels in your server identifies hot-swap or
hot-plug component. You can install or remove hot-swap and hot-plug
components while the system is running, provided that your system is configured
to support this function. For complete details about installing or removing a
hot-swap or hot-plug component, see the detailed information in this chapter.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
v Make sure that you have an adequate number of properly grounded electrical
outlets for your server, monitor, and any other options that you intend to install.
v Back up all important data before you make changes to disk drives.
v For a list of supported options for your server, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
System reliability considerations
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has either a drive or a filler panel installed.
v Each of the power-supply bays has a power supply installed.
v For tower models, make sure that there is at least 50 mm (2 inches) of ventilated
space at the sides of the server and 100 mm (4 inches) at the front and rear of
the server.
For rack configurations, make sure that space is available around the server to
enable the server cooling system to work properly. See the documentation that
comes with the rack for additional information.
v The server cover is in place during normal operation.
v The air-baffle cover over the microprocessors remains closed during normal
operation.
v A removed hot-swap drive is replaced within 2 minutes of removal.
v Cables for optional adapters are routed according to the instructions provided
with the adapters.
v A failed fan is replaced within 48 hours.
v The server is turned off and the power cords are disconnected before you open
the air-baffle cover.
v The air-baffle assembly is always installed in the server except when you are
installing or removing the components that are located under the air-baffle cover.
© Copyright IBM Corp. 2002
41
v When the air-baffle assembly is installed in the server, the air-baffle cover is
always closed.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
microprocessor.
Working inside the server with the power on
Your 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.
v Avoid dropping any metallic objects, such as paper clips, hair pins, or screws,
into the server.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices and your system. 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 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 possibly damage the
device.
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 the device down, place it in its

Adapter considerations
Before you install an adapter, review the following:
v Read the documentation that comes with your operating system.
v Locate the documentation that comes with the adapter and follow those
instructions in addition to the instructions in this chapter. If you need to change
the switch or jumper settings on your adapter, follow the instructions that come
with the adapter.
v You can install full-length adapters and non-hot-plug adapters in any expansion
slot.
v The 32-bit PCI slot supports 5.0 V signaling PCI adapters; it does not support 3.3
V signaling adapters.
v The 64-bit PCI-X slots 2 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:
– Non-hot-plug, 32-bit PCI slot 1 is on PCI bus A, 33 MHz
– Non-hot-plug, 64-bit PCI-X slots 2 and 3, and the integrated Ethernet
controller, are on PCI bus B, 100 MHz (independent of slot 4)
– Non-hot-plug, 64-bit PCI-X slot 4 and the integrated SCSI controller with RAID
capabilities are on PCI bus B, 100 MHz (independent of slots 2 and 3)
– Hot-plug, 64-bit PCI-X slot 5 is on PCI bus C, 133 MHz (independent of slot
6)
– Hot-plug, 64-bit PCI-X slot 6 is on PCI bus C, 133 MHz (independent of slot
5)
Chapter 4. Customer replaceable units
57
Notes:
1. PCI bus A is often referred to as bus 0; PCI bus B is often referred to as bus
1 and bus 2; and PCI bus C is often referred to as bus 3 and bus 5.
However, the bus numbers vary according to the adapters that are installed.
2. If an optional ServeRAID-5i controller is installed, it overrides the standard
functionality of the integrated SCSI controller with RAID capabilities and
forces PCI-X slot 4 to 66 MHz. The ServeRAID-5i controller must be installed
in slot 4 using the 3-U bracket that comes with the controller.
3. The integrated SCSI controller with RAID capabilities is on PCI bus B.
v The optional IBM Remote Supervisor Adapter must be installed in PCI slot 1 only.
Use the ribbon cable that comes with the adapter to connect the adapter to the
Remote Supervisor Adapter connector (J27) 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 SCSI controller with
RAID capabilities (or optional ServeRAID-5i controller), integrated Ethernet
controller, 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 “Starting the Configuration/Setup Utility program” on
page 12).
v The Active PCI-X slots contain:
– Power-on LEDs
– Internal attention LEDs
– External attention LEDs

Installing a hot-plug adapter (slots 5 and 6)
This section contains the procedure for installing a hot-plug PCI or PCI-X adapter. If
your operating system supports hot-plug PCI or PCI-X adapters, you can replace a
failing hot-plug PCI or PCI-X adapter with a new adapter of the same type without
turning off power to the server. If your operating system and adapter also support
the hot-add feature, you can install a new adapter without turning off the power to
the server.
Notes:
1. Although an optional Integrated xSeries Adapter (IXA) can be installed only in
slots 5 and 6, it is not a hot-plug adapter. See “Installing a non-hot-plug adapter
(any slot)” on page 61 for instructions for installing an IXA adapter.
2. Do not remove a hot-plug adapter before performing the operating-systemdefined procedure for disabling the Active PCI-X (hot-plug) slot that contains the
adapter. Failure to do so might cause your system to lock up. See your
operating-system documentation for additional information.
3. You do not have to turn off the server to install hot-plug adapters in the hot-plug
slots. However, you must turn off the server when performing any steps that
involve installing or removing cables.

Cabling example for a ServeRAID controller
You can install an optional IBM ServeRAID controller in your server to control the
internal hot-swap hard disk drives. A ServeRAID controller can, for example, enable
you to configure the internal hot-swap hard disk drives into disk arrays. The
illustrations in this section show the cabling for internal hot-swap hard disk drives.
You can also cable a ServeRAID adapter to external hard disk drives. See your
Chapter 4. Customer replaceable units
63
ServeRAID controller option documentation for complete instructions for installing a
ServeRAID controller in your server and for additional information about ServeRAID
controllers.
Notes:
1. This cabling example does not apply to the ServeRAID-5i controller, which uses
the integrated SCSI controller with RAID capabilities on the system board.
2. An optional ServeRAID-5i controller can be installed only in PCI-X slot 4. Slot 4
is the only PCI-X slot that supports the ServeRAID-5i controller requirements.
3. Connections made to external SCSI devices will be asynchronous.
If you are connecting the adapter to any internal SCSI backplane or device, you will
need to purchase additional SCSI cables. Contact your IBM marketing
representative or reseller for additional information about the number and types of
cables that your server configuration requires.
Your server comes with one SCSI cable that can only be used with the integrated
SCSI controller with RAID capabilities that is on the system board. One end of this
SCSI cable is attached to the connector on the SCSI backplane, and the other end
is attached to the SCSI channel A connector on the system board. The SCSI
channel B connector on the system board is available for use, but the server does
not come with a cable attached to it.
The following procedure describes the cable routing that is necessary when you
install a ServeRAID controller other than ServeRAID-5i.
Notes:
1. See the documentation that comes with your adapter for any cabling
instructions.
2. Cable identifiers are printed on the cables that come with your server and
options. Use these identifiers to connect the cables to the correct connectors.
For example, the hard disk drive cables are labeled “HDD option.”
Complete the following steps to cable the ServeRAID controller:
1. Determine the number of SCSI channels that you want to use on the
ServeRAID controller.
2. Review the information in “Installation guidelines” on page 41, “Handling
static-sensitive devices” on page 42, and “Safety information” on page 163.
3. Turn off the server and disconnect all power cords and external cables
(“Turning off the server” on page 9); then, remove the server cover (see
“Removing the server left-side cover and bezel (tower model)” on page 51 or
“Removing the server top cover and bezel (rack configuration)” on page 53).
4. Lift the adapter-retention clip on top of the adapter-support bracket; then,
remove the full-length adapters.
5. Lift and remove the plastic dividers from PCI-X slots 5 and 6 by lifting the ends
of the dividers out of the adapter support bracket and tilting the dividers up out
of the server.
6. Disconnect internal cables as necessary, remove the air-baffle assembly, and
remove the adapter-support bracket from the server. For complete details, see
“Removing and installing the adapter-support bracket” on page 54.
Note: You must remove the air-baffle assembly whenever you remove the
adapter-support bracket.

7. Disconnect the internal SCSI cable from SCSI connector A (J44) or B (J51) on
the system board. See “System-board internal cable connectors” on page 45
for the location of the SCSI connectors.
Note: The SCSI cables that come with your server can only be used with the
integrated SCSI controller with RAID capabilities. If a RAID controller
other than the ServeRAID-5i isinstalled, you must use SCSI cables that
are compatible with that controller. To select and order the correct
cables for use with your RAID controller, contact your IBM reseller or
IBM marketing representative.
8. Reinstall the adapter-support bracket in the server (see “Removing and
installing the adapter-support bracket” on page 54).
Important: To ensure proper cooling and server operation, you must keep the
air-baffle cover closed.
Note: You must reinstall the air-baffle assembly when you reinstall the
adapter-support bracket. Make sure that no cable is under the
adapter-support bracket or interferes with the center fans (connector
J18).
9. Reinstall the plastic dividers between the Active PCI-X adapter slots.
10. Reinstall the adapters that you removed. If you have not yet installed the
ServeRAID controller, install it now.
See “Installing a hot-plug adapter (slots 5 and 6)” on page 59 or “Installing a
non-hot-plug adapter (any slot)” on page 61 for instructions for installing a
hot-plug or non-hot-plug adapter; then, return to this step.
11. Replace the SCSI cable on the SCSI backplane with the SCSI cable for your
new ServeRAID controller. The SCSI cable being replaced was one of the
cables that was disconnected from the system board in step 7.
12. Route the free end of the SCSI cable from the SCSI backplane through the
adapter-support bracket opening and toward the ServeRAID controller (see the
illustration in step 13).
13. Attach the free end of the SCSI cable to the selected internal SCSI channel
connector on the ServeRAID controller. Make sure that the other end of the
SCSI cable is attached to the connector on the SCSI backplane.
Attention: When you route the SCSI cable, do not block the ventilated space
around any of the fans.
The following illustration shows how to route one SCSI cable to the ServeRAID
controller.

Working with the 3-Pack Ultra320 Hot-Swap Expansion option
Your server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate your system while a hard disk drive is removed or installed. These drives
are known as hot-swap drives. The hot-swap drives are attached to a hot-swap
hard disk drive backplane. The backplane is a printed circuit board behind the drive
bays. For more information about drive bays and drive installation, see “Installing
internal drives” on page 71. The low voltage differential (LVD) SCSI hot-swap hard
disk drive backplane supports a maximum of six slim-high, hot-swap hard disk
drives.
If you install the 3-Pack Ultra320 Hot-Swap Expansion option, you can attach up to
three additional drives. All of these drives must be LVD hard disk drives that
operate at 320 MB per second or lower. The optional 3-Pack Ultra320 Hot-Swap
Expansion Kit contains a hot-swap hard disk drive backplane that you install
adjacent to the standard hot-swap hard disk drive backplane. It also includes the
SCSI cable you need to install the option. Your server supports a maximum of two
hot-swap drive backplanes.
Note: All drives being used in the server should have the same throughput speed
rating: mixing speed ratings might cause all drives to operate at the lower
throughput speed.
Do the following to configure the channels on the two SCSI backplanes:
v You can configure each SCSI channel (bus) independently. This is the typical
backplane configuration. In this configuration:
– The hard disk drives that are connected to the standard backplane are
attached to channel A.
– The hard disk drives that are connected to the 3-Pack Ultra320 Hot-Swap
Expansion option backplane are attached to channel B.
Notes:
1. The standard LVD SCSI backplane is also known as the SCSI backplane or the
hot-swap hard disk drive backplane.
2. The SCSI backplane that comes with the 3-Pack Ultra320 Hot-Swap Expansion
Kit is also known as the 3-Pack backplane.
3. Table 8 on page 107 lists the SCSI identifiers (IDs) for the standard LVD SCSI
backplane and hard disk drives. Table 9 on page 107 lists the SCSI IDs for the
3-Pack backplane and hard disk drives.
4. Cable identifiers are printed on the cables that come with your server and
options. Use these identifiers to connect the cables to the correct connectors.
For example, the hard disk drive cables are labeled “HDD option.”
5. For information about other options and using the 3-Pack Ultra320 Hot-Swap
Expansion option, see the documentation that comes with the option kit.

6. For additional information about cabling, see “Cabling example for a ServeRAID
controller” on page 63 and “Cabling the server” on page 102.
7. The SCSI cables that come with your server can only be used with the
integrated SCSI controller with RAID capabilities. If a RAID controller other than
the ServeRAID-5i is installed, you must use SCSI cables that are compatible
with that controller. To select and order the correct cables for use with your
RAID controller, contact your IBM reseller or IBM marketing representative.

Installing internal drives
If you add different types of drives, your system can read multiple types of media
and store more data. Several types of drives are available, such as:
v Diskette
v Hard disk
v CD-ROM
v DVD-ROM
v Tape, including digital linear tape (DLT), super digital linear tape (SDLT), and
linear tape-open (LTO)
Note: The server supports both internal and external tape drives.
Your server contains hardware that enables you to replace a failed hard disk drive
without turning off the server. Therefore, you have the advantage of continuing to
operate your system while a hard disk drive is removed or installed. These drives
are known as hot-swap drives.
Each hot-swap drive has two indicator LEDs (see “Server controls and indicators”
on page 4). If the amber hard disk status LED for a drive is lit continuously, that
individual drive is faulty and requires replacement. When the hard disk drive status
LED indicates a drive fault, you can replace a hot-swap drive without turning off the
server.
Each hot-swap drive that you plan to install must be mounted in a hot-swap-drive
tray. The drive must have a Single Connector Attachment (SCA) connector.
Hot-swap-drive trays come with hot-swap drives.

LTO drives. For a list of supported options for your server, go to
http://www.ibm.com/pc/us/compat/ on the World Wide Web.
A three-drop power signal cable and a one-drop IDE cable come attached to the
CD-ROM drive. Use this power signal cable to connect the removable-media
drives. The one-drop SCSI signal cable that comes with your server will need to
be replaced with a two-drop SCSI signal cable to provide a signal connection to
the removable-media drives.
v You cannot install hot-swap drives in the removable-media or non-hot-swap drive
bays on the front side of the server, unless you install the 3-Pack Ultra320
Hot-Swap Expansion option.
v Your server supports a maximum of six 1-inch (26 mm) slim-high, 3.5-inch,
hot-swap hard disk drives in the standard hot-swap bays. In the tower model, the
hot-swap bays are arranged vertically in the standard hard disk drive cage; the
bay numbers are 0 through 5 (from bottom to top). In the rack configuration, the
hot-swap bays are arranged horizontally in the standard hard disk drive cage; the
bay numbers are 0 through 5 (from left to right). In the tower model, bays 0
through 5 are below the removable-media drive bays. In the rack configuration,
bays 0 through 5 are to the left of the removable-media drive bays.
Notes:
1. To minimize the possibility of damage to the hard disk drives when you are
installing them in a rack configuration, install the server in the rack before
installing the hard disk drives.
2. You do not have to turn off the server to install hot-swap drives in the hot-swap
drive bays. However, you must turn off the server when performing any steps
that involve installing or removing cables.
3. You can install three additional hot-swap hard disk drives in the server after you
install the 3-Pack Ultra320 Hot-Swap Expansion option (see “Working with the

b. Align the drive assembly with the guide rails in the bay.
c. Gently push the drive assembly into the bay until the drive stops.
d. Push the tray handle to the closed (locked) position.
e. Check the hard disk drive status indicator to verify that the hard disk drive is
operating properly.
If the amber hard disk drive status LED for a drive is lit continuously, that
drive is faulty and needs to be replaced. If the green hard disk drive activity
LED is flashing, the drive is being accessed.
Note: If your server is configured for RAID operation using the integrated SCSI
controller with RAID capabilities or an optional ServeRAID controller, you
might need to reconfigure your disk arrays after installing hard disk

Installing memory modules
Adding memory to your server is an easy way to make programs run faster. You
can increase the amount of memory in your server by installing memory-module
options. When you install memory, you must install a pair of matched dual inline
memory modules (DIMMs).
Notes:
1. The system board contains 6 DIMM connectors and supports two-way memory
interleaving.
2. The DIMM options available for your server are 128 MB, 256 MB, 512 MB, and
1 GB. Your server supports a minimum of 256 MB and a maximum of 6 GB of
system memory.
3. The amount of usable memory will be reduced depending on the system
configuration. A certain amount of memory must be reserved for system
resources. The BIOS will display the total amount of installed memory and the
amount of configured memory.
4. Your server comes with two 128 MB or 256 MB DIMMs, (for a total of 256 MB
or 512 MB memory) installed in the DIMM 5 and DIMM 6 memory connectors
(J14 and J15, respectively). When you install additional DIMMs, be sure to
install them in pairs, with the next pair in DIMM connectors 3 and 4 (J11 and
J12), and the final pair in DIMM connectors 1 and 2 (J7 and J9).
5. Each DIMM in a single pair must be the same size, speed, type, and
technology. You can mix compatible DIMMs from various manufacturers.
6. Each DIMM pair does not have to contain DIMMs of the same size, speed, type,
and technology as the first pair.
7. Install only 133 MHz, 2.5 V, 184-pin, double-data-rate (DDR), PC2100,
registered synchronous dynamic random-access memory (SDRAM) with error
correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest
PC2100 SDRAM Registered DIMM specification. For a list of supported options
for your server, go to http://www.ibm.com/us/compat/ on the World Wide Web.
8. Your server supports Chipkill™ memory if the DIMMs are all type x4 and are
larger than 128 MB. Using any 128 MB DIMMs, or DIMMs that are not type x4,
on your server disables Chipkill memory.
9. You do not need to save new configuration information when installing or
removing DIMMs. The only exception is if you replace a faulty DIMM that was
marked as Disabled in the Memory Settings menu. In this case, you need to
re-enable that memory row in the Configuration/Setup Utility or reload the
default memory settings (see “Choices available from the Configuration/Setup
main menu” on page 12).
Install the DIMMs in the order shown in the following table.

DIMM installation sequence.)
5. Touch the static-protective package that contains the DIMM option to any
unpainted metal surface on the server. Then, remove the DIMM from the
package.
6. To install the DIMMs, repeat the following steps for each DIMM that you install:
a. Turn the DIMM so that the DIMM keys align correctly with the connector on
the system board.
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, handle the clips gently.
b. Insert the DIMM by pressing the DIMM straight into the connector. Be sure
that the retaining clips snap into the closed positions.
Note: If a gap exists between the DIMM and the retaining clips, the DIMM
has not been properly installed. In this case, open the retaining clips
and remove the DIMM; then, reinsert the DIMM.
7. Close the cover on the air-baffle assembly.

Installing an additional microprocessor
Your server comes with one or two microprocessors installed on the system board.
Your server supports up to two microprocessors. With two microprocessors, your
server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain
operating systems and application programs can distribute the processing load
among the microprocessors. If your server comes with one microprocessor, you can
install a second microprocessor.
Before you begin:
v Thoroughly review the documentation that comes with the microprocessor to
determine the required BIOS update. The latest level of BIOS code for your
server is available through the World Wide Web (see “Recovering the BIOS
code” on page 36).
v (Optional) Obtain an SMP-capable operating system. For a list of supported
operating systems and other options, go to http://www.ibm.com/pc/us/compat/ on
the World Wide Web.
Attention: To ensure proper server operation when you install an additional
microprocessor, use microprocessors that have the same cache size and type, and
the same clock speed. Microprocessor internal and external clock frequencies must
be identical. You can use the Configuration/Setup Utility program in your server to
determine the specific type of microprocessor on your system board.
For a list of microprocessors supported by your server, see the ServerProven® list
at http://www.ibm.com/pc/us/compat/ on the World Wide Web.
Important: A boot processor must always be installed in socket U13 of the system
board.
Notes:
1. To order additional microprocessor options, contact your IBM reseller or IBM
marketing representative.
2. When you install a microprocessor in socket U9, you must also install the
voltage regulator module (VRM) that comes with the microprocessor, in VRM
connector J1.
3. The microprocessor sockets in this server contain built-in termination for the
microprocessor bus; therefore, terminator cards are not required for empty
microprocessor sockets. However, for airflow, an empty microprocessor socket
must contain a microprocessor baffle.

Ultra320 SCSI system-board connectors
Your server has an integrated dual-channel Ultra320 small computer system
interface (SCSI) controller. This controller supports two independent, internal
Ultra320 SCSI channels. The SCSI channel connectors are on the system board.
Each channel supports up to 15 SCSI devices. This controller uses:
v Double-transition clocking to achieve up to 320 MB-per-second data-transfer
rates
v Domain name validation to negotiate compatible data-transfer speeds with each
device
v Parity checking to ensure data reliability
v An active terminator for SCSI bus termination
The server comes with one SCSI cable that is connected from the internal SCSI
channel A connector to the standard hot-swap-drive backplane. You can attach
additional internal SCSI devices to the other internal SCSI channel B connector, or
you can use channel B for external SCSI devices. To use channel B for external
SCSI devices, remove the external SCSI knockout from the rear of the server (see
“Cabling the server” on page 102 for external SCSI knockout location) and secure
the free end of an optional channel B cable in the new opening.
If you want to attach external SCSI devices to the server without using the internal
SCSI channel B, you must install an optional SCSI adapter.
Notes:
1. External SCSI devices connected to internal SCSI channel B will operate
asynchronously.
106
xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
2. If you install a PCI RAID adapter to configure and manage the internal hot-swap
drives, you must move the SCSI cable from the system-board SCSI connector
to an internal channel connector on the RAID adapter (except for the
ServeRAID-5i controller, which uses the system-board integrated SCSI controller
with RAID capabilities). See “Cabling example for a ServeRAID controller” on
page 63 for additional information.
SCSI cabling requirements
For information about the maximum length of SCSI cable, see the American
National Standards Institute (ANSI) SCSI standards on the ANSI Web site at
http://www.ansi.org/ on the World Wide Web. Adhering to these standards will help
to ensure that your 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 8 and Table 9 list the SCSI IDs for the hard disk
drives and backplanes that are connected to one channel. In the typical
configuration, the standard hard disk drives and backplane are connected to
channel A, and the optional 3-Pack hard disk drives and backplane are connected
to channel B. See “Working with the 3-Pack Ultra320 Hot-Swap Expansion option”
on page 67 for instructions for installing the 3-Pack option, and “Installing internal
drives” on page 71 for instructions about installing hard disk drives.

Chapter 6. Symptom-to-FRU index
This index supports xSeries 235 servers.
Notes:
1. Check the configuration before you replace a FRU. Configuration problems can
cause false errors and symptoms.
2. For IBM devices not supported by this index, refer to the manual for that device.
3. Always start with “General checkout” on page 25.
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 computer.
The left-hand column of the tables in this index lists error codes or messages, and
the right-hand column lists one or more suggested actions or FRUs to replace.
Note: Some tables have more than two columns; in those instances, more than
one column on the left is required to describe the error symptom.
Take the action (or replace the FRU) suggested first in the list of the right-hand
column, then try the server again to see if the problem has been corrected before
taking further action.
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.

Power cord CRUs
For your safety, IBM provides a power cord with a grounded attachment plug to use
with this IBM product. To avoid electrical shock, always use the power cord and
plug with a properly grounded outlet.
IBM power cords used in the United States and Canada are listed by Underwriter’s
Laboratories (UL) and certified by the Canadian Standards Association (CSA).
For units intended to be operated at 115 volts: Use a UL-listed and CSA-certified
cord set consisting of a minimum 18 AWG, Type SVT or SJT, three-conductor cord,
a maximum of 15 feet in length and a parallel blade, grounding-type attachment
plug rated 15 amperes, 125 volts.
For units intended to be operated at 230 volts (U.S. use): Use a UL-listed and
CSA-certified cord set consisting of a minimum 18 AWG, Type SVT or SJT,
three-conductor cord, a maximum of 15 feet in length and a tandem blade,
grounding-type attachment plug rated 15 amperes, 250 volts.
For units intended to be operated at 230 volts (outside the U.S.): Use a cord set
with a grounding-type attachment plug. The cord set should have the appropriate
safety approvals for the country in which the equipment will be installed.
IBM power cords for a specific country or region are usually available only in that
country or region.

Appendix A. Getting help and technical assistance
If you need help, service, or technical assistance or just want more information
about IBM products, you will find a wide variety of sources available from IBM to
assist you. This appendix contains information about where to go for additional
information about IBM and IBM products, what to do if you experience a problem
with your xSeries or IntelliStation system, and whom to call for service, if it is
necessary.
Before you call
Before you call, make sure that you have taken these steps to try to solve the
problem yourself:
v Check all cables to make sure that they are connected.
v Check the power switches to make sure that the system is turned on.
v Use the troubleshooting information in your system documentation, and use the
diagnostic tools that come with your system.
v Go to the IBM Support Web site at http://www.ibm.com/pc/support/ to check for
technical information, hints, tips, and new device drivers.
v Use an IBM discussion forum on the IBM Web site to ask questions.
You can solve many problems without outside assistance by following the

Appendix B. Related service 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.
Safety information
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.

Electrical safety
CAUTION:
Electrical current from power, telephone, and communication cables can be
hazardous. To avoid personal injury or equipment damage, disconnect the
attached power cords, telecommunication systems, networks, and modems
before you open the server covers, unless instructed otherwise in the
installation and configuration procedures.
Observe the following rules when working on electrical equipment.
Important: Use only approved tools and test equipment. Some hand tools have
handles covered with a soft material that does not insulate you when
working with live electrical currents.
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.
v 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.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Disconnect all power before:
– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units
v 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.
v 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.
164
xSeries 235 Type 8671: Hardware Maintenance Manual and Troubleshooting Guide
v Regularly inspect and maintain your electrical hand tools for safe operational
condition.
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:
Appendix B. Related service information
165
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.
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.
166
