ServerGuide features
Features and functions can vary slightly with different versions of the ServerGuide
program. To learn more about the version that you have, start the ServerGuide
Setup and Installation CD and view the online overview. Not all features are
supported on all server models.
The ServerGuide program requires a supported IBM server with an enabled
startable (bootable) CD-ROM drive. In addition to the ServerGuide Setup and
Installation CD, you must have your operating system CD to install your operating
system.
The ServerGuide program has the following features:
v Sets system date and time.
v Detects an installed SCSI RAID adapter or controller and runs the SCSI RAID
configuration program. (Does not apply to the integrated SCSI controller with
RAID capabilities.)
v Updates the licensed internal code (firmware) level without diskettes.
v Checks the system BIOS code and microcode (firmware) levels of supported
options to determine whether a later level is available from the CD. You can
perform updates without using diskettes.
v Provides the Performance Optimizer program to easily tune your SCSI RAID
adapter settings for your server environment.
v Creates a System Partition on the default drive. You can run server-specific utility
programs after setup.
v Detects installed hardware options and provides updated device drivers for most
adapters and devices.
v Creates a setup-replication diskette for replicating setup selections for other
servers of the same model.
v Provides diskette-free installation for supported operating systems.
v Provides a replicated installation path for multiple installations of supported
operating systems.
v Includes an online README file with links to tips for your hardware and
operating system installation.
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:
12 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
– 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.
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
2. Diagnostics for your server come in BIOS code or on a separate diagnostics
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.
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.

Chapter 2. Configuring your server 13
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.
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 an 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.
14 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
3. From the Family drop-down list, select your server model.
4. If operating system installation instructions are available for your server model,
OS installation is in the list in the upper-left corner of the Web page. Click OS
installation and select the instructions for your operating system.
Using ServeRAID Manager
You can use the ServeRAID™Manager program, which is on the IBM ServeRAID
Support CD, to:
v Configure a redundant array of independent disks (RAID)
v Restore a SCSI hard disk drive to factory-default settings, erasing all data from
the disk
v View your RAID configuration and associated devices
v Monitor operation of your RAID controllers
You can run ServeRAID Manager in startable-CD mode from the IBM ServeRAID
Support CD or as an installed program. For information about installing ServeRAID
Manager, see the documentation on the CD.
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.
Before you install your operating system, you must configure the controller that is
attached to the hard disk drives. Use the configuration program on the IBM
ServeRAID Support CD to configure the integrated SCSI controller with RAID
capabilities or to configure an optional IBM ServeRAID controller.
Notes:
1. You cannot use the ServerGuide Setup and Installation CD to configure the
optional controllers.
2. To update the firmware and BIOS code for an optional ServeRAID controller,
you must use the IBM ServeRAID Support CD that comes with the ServeRAID
option.
Using the LSI Logic Configuration Utility program
LSI Logic Configuration is a built-in, menu-driven configuration utility program that
you can use to:
v Perform a low-level format of a SCSI hard disk drive
v Set a SCSI device scan order
v View or change SCSI IDs for attached devices
v Set SCSI protocol parameters on SCSI hard disk drives
Chapter 2. Configuring your server 15
Notes:
1. The integrated SCSI controller with RAID capabilities in your server supports
redundant array of independent disks (RAID). You can use the LSI Logic
Configuration Utility program to configure RAID level 1 for a single pair of
attached devices.
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.
The following sections provide the instructions for starting and running the LSI Logic
Configuration Utility program and performing selected functions.
Starting the LSI Logic Configuration Utility program
Complete the following steps to start the LSI Logic Configuration Utility program:
1. Turn on the server.
2. When the prompt <<< Press <CTRL><C> to start LSI Logic Configuration
Utility >>> appears, press Ctrl+C. If you have set an administrator password
you are prompted to type the password.
3. Use the arrow keys to select a controller (channel) from the list of adapters;
then, press Enter.
4. Follow the instructions on the screen to change the settings of the selected
items; then, press Enter. The Device Properties and Mirroring Properties
choices produce additional screens of parameters to review or change.
Formatting a SCSI hard disk drive
Low-level formatting removes all data from the hard disk. If there is data you want
to save, back up the hard disk before performing this procedure. Complete the
following steps to format a drive.
Note: Before you format a SCSI hard disk, make sure that it is not part of a
mirrored pair. From the list of adapters, select the controller (channel) for the
drive to format. Select Mirroring Properties and make sure the mirroring
value for the drive is set to None.
1. From the list of adapters, select the controller (channel) for the drive to format.
2. Select Device Properties.
3. Use the arrow keys (↑ or ↓) to highlight the drive to format.
4. Use the arrow keys (← or →) or the End key to scroll to the right.
5. Select Format; then, press Enter to begin the low-level formatting operation.
Configuring the Gigabit Ethernet controller
The Ethernet controller is integrated on the system board. It provides an interface
for connecting to a 10-Mbps, 100-Mbps, or 1000-Mbps network and provides full
duplex (FDX) capability, which enables simultaneous transmission and reception of
data on the network. If the Ethernet port in the server supports auto-negotiation, the
controller detects the data-transfer rate of the network (10BASE-T, 100BASE-TX, or
1000BASE-T) and automatically operates at that rate, in full-duplex or half-duplex
mode, as appropriate. The Ethernet controller supports optional modes, such as
teaming, priority packets, load balancing, fault tolerance, and virtual LANs, which
provide better performance, security, and throughput. These modes apply to the
integrated Ethernet controller and to controllers on supported Ethernet adapters.
16 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
You do not need to set any jumpers or configure the controller. However, you must
install a device driver to enable the operating system to address the controller. The
device drivers are available on the Broadcom NetXtreme Gigabit Ethernet Software
CD. For the latest device drivers and information about configuring your Ethernet
controller, go to the IBM Support Web site at http://www.ibm.com/pc/support.

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 129 for more
information.
General checkout
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
These programs provide the primary methods of testing the major components of
the server.
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 server might be part of a shared DASD cluster (two or more servers
sharing one or more external storage devices). Before you run diagnostics, verify
that the failing server is not part of a shared DASD cluster.
A server might be part of a cluster if:
v The server is identified as part of a cluster.
v One or more external storage units are attached to the server and at least one of
the attached storage units is also attached to another server or unidentifiable
source.
v One or more servers are located near the failing server.
If the failing server 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 servers 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 server stops with a POST error, go to “POST error codes” on page 112
4. If the server stops and no error is displayed, go to “Undetermined problems” on
page 121
5. For power supply problems, see “Power checkout” on page 29
6. For safety information, see “Safety information” on page 131
7. For intermittent problems, check the error log.

POST error codes and messages
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/or an error message
appears on your screen. See “Beep symptoms” on page 103 and “POST error
codes” on page 112 for more information.
Note: A single problem might cause several error messages. When this occurs,
work to correct the cause of the first error message. After you correct the
cause of the first error message, the other error messages usually will not
occur the next time you run the test.
The POST error log contains the three most recent error codes and messages that
the system generated during POST.
The System Error log 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.

Diagnostic programs, error codes, and messages
The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD.
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.
Chapter 6, “Symptom-to-FRU index,” on page 103 contains 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
was encountered. (These codes are for trained service personnel;
see “Diagnostic error codes” on page 105).
iii is the three-digit device ID. (These codes are for trained service
personnel; see “Diagnostic error codes” on page 105).
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.
Chapter 3. Diagnostics 23
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
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

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.

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.
Follow this general procedure for troubleshooting power problems:
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
111).
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 111).
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.
Chapter 3. Diagnostics 29
v Check the Ethernet controller LEDs on the rear of the server.
These LEDs indicate whether a problem exists 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
your 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).

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 available from the World
Wide Web.
v Reseat or replace the adapter.
Check the following:
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.
Check the following:
v Make sure that you have loaded the network device drivers.
v The network might be idle. Try sending data from this server.

Installation guidelines
Before you begin to install options in your server, read the following information:
v Review “Safety information” on page 131 These guidelines will help you work
safely with your server and options.
v When you need to access the inside of the server to install options, you might
find it easier to lay the server on its side. Before laying the server on its side,
rotate the two front stabilizing feet a quarter turn inward toward the server, so
that they do not break. Before returning the server to an upright position, rotate
the front stabilizing feet a quarter turn outward from the server. See “Moving the
stabilizing feet” on page 40 for more information.
v Make sure that you have an adequate number of properly grounded electrical
outlets for your server, monitor, and other devices that you will connect to the
server.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v You do not need to turn off the server to install or replace hot-swap power
supplies, hot-swap drives, or hot-plug Universal Serial Bus (USB) devices.
v The blue color on components and labels identifies touch points where you can
grip a component, move a latch, and so on.
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 system 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.
v If the server has redundant power, each of the power-supply bays has a power
supply installed.
v There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2 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 (over 30 minutes) with the
server cover removed might damage server components.
When installing the server in a rack, 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 You have followed the cabling instructions that come with optional adapters.
v You replace a failed fan as soon as possible.
v You replace a hot-swap drive within 2 minutes of removal.
v Cables for optional adapters are routed according to the instructions provided
with the adapters.
v You do not remove the air baffle when the server is operating. 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.
Chapter 4. Installing options 37
Server power features
When the server is connected to an ac power source but is not turned on, the
operating system does not run, and all core logic except for the service processor is
shut down; however, the server can respond to requests from the service processor,
such as a remote request to turn on the server. The power-on LED flashes to
indicate that the server is connected to an ac power source but is not turned on.
Turning on the server
Notes:
1. Turn on all external devices, such as the monitor, before turning on the server.
2. The power-on LED on the front of the server is lit when the server is on and
while it is powering-up.
3. You can install a circular disk over the power-control button to prevent
accidental manual power-off. This disk, known as the power-control button
shield, comes with your server.
Approximately 20 seconds after the server is connected to ac power, the
power-control button becomes active, and you can turn on the server and start the
operating system by pressing the power-control button. The server can also be
turned on in any of the following ways:
v If a power failure occurs while the server is turned on, the server will restart
automatically when power is restored.
v If the server is connected to an ASM interconnect network that contains at least
one system with an optional Remote Supervisor Adapter installed, the server can
be turned on from the Remote Supervisor Adapter user interface.
v If an optional Remote Supervisor Adapter is installed in the server, the server can
be turned on from the Remote Supervisor Adapter user interface.
v When you plug in your server for the first time, the Wake on LAN feature can
turn on the server. If your server was previously turned on, it must be properly
turned off for the Wake on LAN feature to turn on the server.
v If your server was previously turned on, it must be properly turned off for the
Wake on LAN feature to turn on the server.
Note: When 4 GB or more of memory (physical or logical) is installed, some
memory is reserved for various system resources and is unavailable to the
operating system. The amount of memory that is reserved for system
resources depends on the operating system, the configuration of the server,
and the configured PCI options.
38 IBM xSeries 225 Type 8647: Hardware Maintenance Manual and Troubleshooting Guide
Turning off the server
When you turn off the server and leave it connected to ac power, the server can
respond to requests from the service processor, such as a remote request to turn
on the server. To remove all power from the server, you must disconnect it from the
power source.
Some operating systems require an orderly shutdown before you turn off the server.
See your operating-system documentation for information about shutting down the

Working with adapters
Your server comes with adapter connectors or slots. The standard video adapter is
installed in mini-PCI slot 6 (PCI6). You can install up to five additional optional
adapters in PCI slot 1 (PCI1) and PCI-X slots 2 through 5 (PCI2 through PCI5).
See “System board” on page 34 for the locations of expansion slots on the system
board.
Adapter considerations
Before you install an adapter, review the following information:
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 Installation of an AGP video adapter in the AGP slot is not supported.
v You can install a only 32-bit adapter in the 32-bit PCI slot 1 and 64-bit adapters
in the 64-bit PCI-X slots 2 through 5.
v You can install full-length adapters in all five expansion slots; however,
double-width adapters will not fit in slot 5 and are not supported. None of the
expansion slots are hot-plug.
v The 32-bit PCI slot 1 supports 5.0 V signaling PCI adapters; it does not support
3.3 V signaling adapters or 64-bit adapters.
v The 64-bit PCI-X slots 2 through 5 support 3.3 V signaling PCI or PCI-X
adapters; they do not support 5.0 V signaling adapters.
v The PCI bus configuration is as follows:
– The 32-bit PCI slot 1 and mini-PCI slot 6 (video adapter) are on the 33 MHz
PCI bus.
Note: Do not install any adapters other than the standard video adapter in
mini-PCI slot 6. Other adapter types are not supported.
– The 64-bit PCI-X slots 2 and 3 and the integrated Ethernet controller are on
the 100 MHz PCI-X bus, channel A.
– The 64-bit PCI-X slots 4 and 5 and the integrated SCSI controller with RAID
capabilities are on the 100 MHz PCI bus, channel B. 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 slots 4
and 5 to 66 MHz.
v The optional IBM Remote Supervisor Adapter can be installed only in PCI slot 1.
Use the ribbon cable that comes with this adapter to connect it to the Remote
Supervisor Adapter connector (JMGT1) on the system board.
v The optional ServeRAID-5i controller can be installed only in PCI-X slot 4 and
must use the 3-U bracket that comes preinstalled on the controller.
v To provide failover protection, an optional Ethernet adapter can be installed only
in PCI-X slots 2 through 5.
v The server scans the AGP slot, mini-PCI slot 6, PCI expansion slot 1, and PCI-X
expansion slots 2 through 5 to assign system resources. Then, the server starts
the PCI devices in the following order, if you have not changed the default
startup sequence: AGP slot, mini-PCI slot 6, PCI expansion slot 1, system-board
integrated drive electronics (IDE) or SCSI devices (including optional
ServeRAID-5i controller), and then PCI-X expansion slots 2 through 5.

Chapter 4. Installing options 49
Some server models contain hardware that supports hot-swap drives, which you
can replace without turning off the server.
Internal drive bays
All server models come with an IDE CD-ROM drive in bay 1 and a 2.3-in., 1.44 MB
diskette drive in bay 3. Depending on your server model it will also come with either
six hot-swap hard disk drive bays or a hard disk drive in bay 7. Internal drives are
installed in bays.

Note: The SCSI IDs for the hot-swap drives are printed on the hot-swap lock bar,
immediately adjacent to the hot-swap drive bays (see Table 6 on page 54).
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.
The integrated IDE controller in your server supports the connection of up to four
IDE devices.
Some server models support a maximum of six 1-inch (26 mm) slim-high, 3.5-inch,
hot-swap hard disk drives in the hot-swap bays. The hot-swap bays are arranged
vertically in the hard disk drive cage; the bay numbers are 1 through 6 (from bottom
to top). Bays 1 through 6 are below the removable-media drive bays.
Diskette drives, tape drives, CD-ROM, DVD/CD-RW, and DVD-ROM drives are
examples of removable-media drives. You can install removable-media drives in
bays 1, 2, and 3 only.
You can install a 3.5-in. slim-high or 5.25-in. half-high removable-media drive, such
as a tape backup drive, in bay 2. The server supports half-high DLT, SDLT, and 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. To install a 3.5-in. drive in a 5.25-in. bay, you
must use the 5.25-in. conversion kit, supplied with the option.
The electromagnetic interference (EMI) integrity and cooling of the server are
protected by having all bays and PCI slots covered or occupied. When you install a
drive or PCI adapter, save the EMC shield and filler panel from the bay or the PCI
adapter slot cover in the event you later remove the option.
Chapter 4. Installing options 51
Notes:
1. To minimize the possibility of damage to the hard disk drives when you are
installing a hard disk drive in a rack model, install the rack model 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.
Working with 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 49
The low voltage differential (LVD) SCSI hot-swap hard disk drive backplane
supports a maximum of six slim-high, hot-swap hard disk drives.
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.
Each hot-swap drive has two indicator LEDs (see the User’s Guide on the IBM
xSeries Documentation CD). If the amber hard disk drive status LED for a drive is lit
continuously, that drive is faulty and requires replacement. When the hard disk drive
status LED indicates a drive fault, you can replace the drive without turning off the
server.
For increased security, the hot-swap drives and filler panels are locked in the server
by the hot-swap lock bar. The hot-swap lock bar cannot be released, allowing
installation and removal of the hot-swap drives and filler panels, unless the key lock
on the server side cover is unlocked.
Note: All drives being used in the server should have the same speed rating:
mixing speed ratings will cause all drives to operate at the lower speed.
The hard disk drives that are connected to the standard backplane are attached to
channel A.
Notes:
1. Table 6 on page 54 lists the SCSI identifiers (IDs) for the standard LVD SCSI
backplane and hard disk drives.
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.
3. For additional information about cabling, see “Cabling an optional SCSI adapter”
on page 48 and “Connecting external options” on page 73

If the amber hard disk drive status light for a drive is lit continuously, that
drive is faulty and needs to be replaced. If the green hard disk drive activity
light is flashing, the drive is being accessed.
Chapter 4. Installing options 53
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
drives. See the ServeRAID documentation on the IBM ServeRAID
Support CD for additional information on RAID operation and complete
instructions for using ServeRAID Manager.
6. If you are installing additional hot-swap hard disk drives, do so now; otherwise,
continue with step 7

into the slots on the front bezel and rotate it to the locked position.
8. Hold the hot-swap lock bar in the closed position, lock the side cover key lock,
and close the server door.
The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. The SCSI ID for each hot-swap hard disk drive is printed on the hot-swap
lock bar. Table 6 lists the SCSI IDs for the hard disk drives and backplane that are
connected to one channel in hot-swap hard disk drive models. In the typical
configuration, the standard hard disk drives and backplane are connected to
channel A.

Power and signal cables for internal drives
Your server uses cables to connect IDE and SCSI devices to the power supply and
to the system board. (See “System board internal cable connectors” on page 34 for
the location of system-board connectors.) Review the following information before
connecting power and signal cables to internal drives:
v The drives that are preinstalled in your server come with power and signal cables
attached. If you replace any drives, remember which cable is attached to which
drive.
v When you install a drive, ensure that one of the drive connectors of the signal
cable is connected to the drive and that the connector at the other end of the
signal cable is connected to the system board.
v The server has two IDE buses, primary and secondary. Each of these buses
supports up to two IDE devices. The primary IDE bus uses connector IDE1 on
the system board and the secondary IDE bus uses connector IDE2.
v If you have only one IDE device on a cable, it must be set as a master device.
v If two IDE devices are used on a single cable, one must be designated as the
master device and the other as the subordinate device; otherwise, the server
might not recognize some of the IDE devices. The master and subordinate
designation is determined by switch or jumper settings on each IDE device.
The following cables are provided:
v Power cables: Four-wire power cables connect the drives to the power supply.
At the end of these cables are plastic connectors that can be attached to
different drives; these connectors vary in size.
v Signal cables: Signal cables are typically flat cables, also called ribbon cables,
that connect IDE, SCSI, and diskette drives to the system board. Two or three
types of signal cable come with your server:
– IDE: The wider IDE signal cable has three connectors. One of these
connectors is attached to the drive, one is a spare, and the third is attached to
the primary or secondary IDE connector on the system board. The spare
connector can be used to connect an additional IDE drive to your server.
The CD-ROM drive is attached to an ATA 100 signal cable. ATA 100 signal
cables are color-coded. The blue connector is attached to the system board.
The black connector is attached to the master IDE device. The gray middle
connector is attached to the subordinate IDE device.
– Diskette drive: The narrower signal cable has two connectors. One is
attached to the diskette drive, and the other is attached to the connector
(FDD1) on the system board.
– SCSI: A round SCSI cable connects SCSI devices to the integrated SCSI
controller with RAID capabilities on the system board. For hot-swap models,
the maximum cable length that supports Ultra320 SCSI hard disk drives is 16
inches. For more information about connecting SCSI devices, see the SCSI
documentation.
Chapter 4. Installing options 59
Installing memory modules
You can increase the amount of memory in your server by installing memory
modules. Your server uses industry-standard PC2100 double-data-rate (DDR) dual
inline memory modules (DIMMs).
Notes:
1. The system board contains four DIMM connectors and supports two-way
memory interleaving.
2. The DIMM options available for your server are 128 MB, 256 MB, 512 MB, 1
GB, and 2 GB. Your server supports a minimum of 256 MB and a maximum of 8
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 512 MB or
1024 MB) installed in the DIMM 3 and DIMM 4 memory connectors. When you
install additional DIMMs, be sure to install them as a pair in DIMM connectors 1
and 2.
5. DIMMs must be installed in matched pairs. The first pair of DIMMs you install in
DIMM 3 and DIMM 4 memory connectors must be the same size, speed, type,
and technology. You can mix compatible DIMMs from various manufacturers. If
you install a second pair of DIMMs in DIMM 1 and DIMM 2 memory connectors,
they do not have to be the same size, speed, type, and technology as the
DIMMs you installed in DIMM 3 and DIMM 4 memory connectors. However, the
size, speed, type, and technology of the DIMMs you install in DIMM 1 and
DIMM 2 memory connectors must match each other.
6. Install only 133 MHz (memory bus), 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.
7. Your server supports Chipkill

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.
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 the User’s Guide on the
IBM xSeries Documentation CD for the World Wide Web addresses.
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.
Important: A microprocessor must always be installed in socket CPU1 of the
system board.
Notes:

Some options have device drivers that you need to install. See the documentation
that comes with your option for information about installing any required device
drivers.
Your server comes with one or two microprocessors installed on the system board.
If your server comes with two microprocessors, or if your server comes with one
microprocessor and you have installed an additional microprocessor, your server
can now operate as an SMP server. Therefore, you might need to upgrade your
operating system to support SMP. See the ServerGuide information in the User’s
Guide on the IBM xSeries Documentation CD and to your operating-system
documentation for additional information.
If your server has a RAID configuration using the integrated SCSI controller with
RAID capabilities or has a ServeRAID controller installed and you have installed or
removed a hard disk drive, see the ServeRAID documentation on the IBM
ServeRAID Support CD for information about configuring your disk arrays.
Connecting external options
If you install an optional SCSI adapter, or use channel B on the integrated SCSI
controller for external devices, you can attach external SCSI devices, such as a
SCSI storage expansion enclosure, to your server. To use channel B for external
SCSI devices, remove the SCSI knockout from the rear of the server and secure
the free end of the channel B cable in the new opening.
You can attach additional external options to the input/output (I/O) connectors on
the front and rear of your server. (See “Input/output ports” on page 74 for more
information.)

port to operate in bidirectional mode, it supports the ECP and EPP modes of
operation. To configure the parallel port, use the Devices and I/O Ports option in
the Configuration/Setup Utility program. See the User’s Guide for more information.
If you configure the parallel port to operate in bidirectional mode, use an IEEE
1284-compliant cable that does not exceed 3 meters (9.8 ft).
Serial connectors
Use the serial connectors to connect serial devices. The following illustration shows
a serial connector.
Ultra320 SCSI connector
You can install up to four internal SCSI devices using the SCSI cable that comes
with some models of the server. Other server models might come 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 SCSI
knockout from the rear of the server 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.
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 an optional SCSI adapter” on page 48 for
additional information.

Your server has an integrated SCSI controller with RAID capabilities. This
dual-channel controller supports two independent, Ultra320 SCSI channels. The
SCSI connectors for both channels 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 Cyclic-redundancy checking (CRC), instead of the usual parity checking, to
improve data reliability
v An active terminator for SCSI bus termination
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.
The hot-swap-drive backplane controls the SCSI IDs for the internal hot-swap drive
bays. However, when you attach an external SCSI device to an optional SCSI
adapter, you must set a unique ID for the device. See the information that comes
with the device for instructions to set its SCSI ID.
SCSI cabling requirements
You can install four internal SCSI devices using the SCSI signal cable that comes
with some server models. If you plan to attach external SCSI devices, you must
order an additional SCSI cable, remove the SCSI knockout from the rear of the
server, and connect the new cable from the system board to this opening. To select
and order the correct cables for use with external devices, contact your IBM reseller
or IBM marketing representative. When using an optional SCSI adapter, you must
also connect the SCSI adapter to the SCSI LED (J18) connector on the system
board receive an indication of SCSI hard-disk drive activity. See “System board
internal cable connectors” on page 34 for the location of the SCSI connectors. 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.
Universal Serial Bus connectors
Use a USB connectors to connect a USB device. USB technology transfers data at
up to 12 megabits per second (Mbps) with a maximum of 127 external devices and
a maximum signal distance of 5 meters (16 ft) per segment. Using Plug and Play
technology, USB devices are configured automatically. The following illustration
shows a USB connector.
Chapter 4. Installing options 77
Use a 4-pin USB cable to connect external devices to USB connectors. If you need
to connect more USB devices than the server has USB connectors for, use a USB
hub to connect additional devices.
If you connect a PS/2 (non-USB) keyboard to the keyboard connector, USB ports
and devices are disabled during power-on self-test (POST).
If you connect a USB keyboard that has a mouse port, the keyboard emulates a
mouse, and you cannot disable the mouse settings in the Configuration/Setup Utility
program.
Video connector
The super video graphics array (SVGA) video adapter is installed in mini-PCI slot 6
on the system board. There is one video connector on the rear of the server. Use
the video connector to connect a monitor or other display. The following illustration
shows an industry standard 15-pin analog video connector on the rear of the server.
