during the initial installation of your server to configure basic hardware features,
such as ServeRAID
operating system (NOS) installation. (See “Using the ServerGuide Setup and
Installation CD” for more information.)
v Configuration/Setup Utility
This program is part of the basic input/output system (BIOS) code that comes
with your server. You can use this program to configure serial port assignments,
change interrupt request (IRQ) settings, change the drive startup sequence, set
the date and time, and set passwords. You also can use this program to view the
system configuration settings, for example, the number of installed
microprocessors, the amount of installed memory, the BIOS diagnostics version
level, and so on. See “Using the Configuration/Setup Utility program” on page 11
for more information.
v ServeRAID programs
The ServeRAID programs come with your server. If your server has a ServeRAID
adapter installed or if you are using the RAID capabilities of the integrated SCSI
controller, you can use the ServeRAID Manager program to define and configure
your disk-array subsystem before you install your operating system. See “Using
ServeRAID Manager” on page 13 for more information.
v LSI Logic Configuration Utility
With the built-in LSI Logic Configuration Utility program, you can configure the
integrated SCSI controller and the devices that attach to it. See “Using the LSI
Logic Configuration Utility program” on page 20.
v Integrated System Management
To update the Integrated System Management (ISM) firmware, see “Updating the
integrated system management firmware” on page 21 for more information.

Using the ServerGuide Setup and Installation CD
The ServerGuide Setup and Installation CD includes an easy-to-use setup and
installation program that is specifically designed for your IBM server. The
ServerGuide program detects the server model and hardware options that are
installed and uses that information during setup to configure the hardware. The
© Copyright IBM Corp. 2002 9
Page 20
ServerGuide program simplifies network operating system (NOS) installations by
providing updated device drivers and, in some cases, installing them automatically.
If a later version of the ServerGuide program is available, you can download a free
image of the ServerGuide Setup and Installation CD, or you can purchase the CD.
To download the latest ServerGuide program, go to the IBM ServerGuide Web page
at http://www.ibm.com/pc/qtechinfo/MIGR-4ZKPPT.html. To purchase the latest
ServerGuide Setup and Installation CD, see the “ServerGuide Updates” flyer that
comes with your server library, or go to the ServerGuide fulfillment Web site at
http://www.ibm.com/pc/coupon/.
The ServerGuide program has the following features to make setup easier:
v An easy-to-use interface with online help
v Diskette-free setup, and configuration programs that are based on detected
v A system BIOS update program, which updates the BIOS code directly from the
v Device drivers that are provided for your server model and detected hardware
v NOS partition size and file-system type that are selectable during setup
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.
hardware
CD
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 NOS 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 NOS that you are installing. This section describes a typical
ServerGuide NOS installation.
Note: Features and functions can vary slightly with different versions of the
ServerGuide Program.
1. After you have completed the setup process, the NOS installation program
starts. (You will need your NOS 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 NOS installation program.
3. With some NOS installations, you can create a NOS-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 NOS partition options that are based on
your NOS selection and the installed hard disk drives.

Page 21
5. If you are installing the NOS 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 NOS CD and restart the
server. At this point, the installation program for the NOS 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 NOS-replication diskette, which contains information that you need
to complete multiple installations. Not all operating systems support NOS-replication
diskettes.
Installing your NOS without ServerGuide
If you have already configured the server hardware and you decide not to use the
ServerGuide program to install your NOS, complete the following steps to download
the latest NOS 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.

Supervisor Adapter is installed in your server
Chapter 2. Configuring your server 11
Page 22
3. Follow the instructions that appear on the screen.
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.
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 system to start the operating
system. 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

switch block 1) 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.
3. Changing the position of the power-on password override switch bypasses
the power-on password check the next time the server is turned 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.
4. Changing the position of this switch does not affect the administrator
password.
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.
Note: This choice is available on the Configuration/Setup Utility menu only if the
optional IBM Remote Supervisor Adapter is installed in your server.
When you use an administrator password, 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.
Attention: If an administrator password is set and then forgotten, it cannot be
overridden or removed. You must replace the system board.

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 drive 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
The following sections provide instructions for running ServeRAID Manager in
Startable CD mode to configure your integrated SCSI controller with RAID
capabilities and perform an initial RAID configuration on your server. See the
ServeRAID documentation on the IBM ServeRAID Support CD for additional
information about RAID technology and 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. If a ServeRAID-5i controller is installed and later
removed, you must re-enable the on-board SCSI controller in using the
Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility
program” on page 11).
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.
Using ServeRAID Manager in Startable CD mode
The information in this section focuses on using the ServeRAID Manager program
in Startable CD mode to configure your controller. For information about installing
ServeRAID Manager, see the documentation on the IBM ServeRAID Support CD.
Chapter 2. Configuring your server 13
Page 24
When you run the ServeRAID Manager program from the startable IBM ServeRAID
Support CD, you are using Startable CD mode, in which you can configure your
controller before you install your operating system.
To run the ServeRAID Manager program in Startable CD mode, turn on the server;
then, insert the IBM ServeRAID Support CD into the CD-ROM drive. If the
ServeRAID Manager program detects an unconfigured controller and ready drives,
the program automatically starts the Configuration wizard, and a window similar to
that shown in Figure 1 opens.
Figure 1. “Configuration wizard” window
Configuring the controller
You can use the Configuration wizard to configure your controller. The Configuration
wizard provides two configuration options: Express and Custom. Express
configuration automatically configures your controller, and you can use Custom
configuration to configure your controller manually.
Note: If the integrated RAID controller has two channels, it will appear in the
ServeRAID Manager tree as two controller objects. However, you can
configure only one array and one RAID level-1 logical drive.
Using Express configuration: Express configuration automatically configures
your controller, creates an array by grouping together the first two physical drives
that appear in the ServeRAID Manager tree, and it creates a RAID level-1 logical
drive.
Complete the following steps to use Express configuration:
1. In the ServeRAID Manager tree, click the controller.
2. Click Express configuration.
3. Click Next. The “Configuration summary” window opens.

Updating the integrated system management firmware
To update the integrated system management (ISM) firmware for the integrated
system management processor (ISMP), you must download the image of the
Integrated System Management Firmware Update Utility program for your server
from the IBM Support Web site at http://www.ibm.com/pc/support/ on the World
Wide Web. You can then run the Integrated System Management Firmware Update
Utility program to create an Integrated System Management Firmware Update Utility
diskette that is used 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 ISMP 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,
go back and start with step 1.
4. From the main menu, select Update System Management Firmware and
press Enter.
5. Follow the on-screen instructions to complete the update.
Configuring the Ethernet controller
The server comes with an integrated dual-port Ethernet controller. This controller
provides an interface for connecting to 10-Mbps, 100-Mbps, and 1000-Mbps
networks and provides full-duplex (FDX) capability, which enables simultaneous
transmission and reception of data on the Ethernet local area network (LAN).
To use the Ethernet controller, connect a Category 5 or higher unshielded
twisted-pair (UTP) cable to either of the two Ethernet ports on the rear panel of the
server.
The Ethernet connectors on the rear panel each have two LEDs. When the
Ethernet link-status LED is on, there is an active connection on the Ethernet port.
When the Ethernet transmit/receive TX/RX LED is on, there is activity between the
Chapter 2. Configuring your server 21
Page 32
server and the network. For a description of the server Ethernet ports, see the
Option Installation Guide on the IBM xSeries Documentation CD.
When you connect the server to the network, the Ethernet controller automatically
detects the data-transfer rate (10 Mbps, 100 Mbps, or 1000Mbps) on the network
and sets the controller to operate at the appropriate rate. In addition, if the Ethernet
port that the server is connected to supports auto-negotiation, the 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), Gigabit Ethernet (1000BASE-T), half
duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and
full-duplex (FDX) modes at all speeds.
The Ethernet controller is a PCI Plug and Play device. You do not need to set any
jumpers or configure the controller for the operating system before you use the
controller. However, you must install a device driver to enable the operating system
to access the controller. The device driver is provided on the ServerGuide Setup
and Installation CD.
High-performance Ethernet modes
If you install an optional Ethernet adapter, or use both Ethernet ports on your
server, you can use optional modes, such as teaming, priority packets, and virtual
LANs, which provide higher performance and throughput for the server. These
modes apply to the integrated Ethernet controller and to the controllers on the
supported Ethernet adapters.
Teaming mode
Teaming options increase throughput and fault tolerance when running with
Windows NT, Windows 2000, or NetWare 4.1x or later.
v Adapter fault tolerance (AFT) provides automatic redundancy for the Ethernet
controller. If the primary controller fails, the optional Ethernet adapter takes over.
Adapter fault tolerance supports from 2 to 4 controllers per team.
v Adaptive load balancing (ALB) enables you to balance the transmission data
flow among 2 to 4 Ethernet controllers. ALB also includes the AFT option. You
can use ALB with any 100BASE-TX or 1000BASE-T switch.
v Cisco Fast EtherChannel (FEC) creates a team of 2 to 4 Ethernet controllers to
increase transmission and reception throughput. FEC also includes the AFT
option. You can only use FEC with a switch that has FEC capability.
Priority Packet mode
Priority Packet is a traffic-prioritization utility that you can use to set up filters to
process high-priority traffic before normal traffic. You can send information from
critical nodes or applications with an indicated priority. Because you set this priority
at the host or entry point of the network, the network devices can base forwarding
decisions on priority information defined in the packet.
Priority Packet information is available on the IBM Networking Web site at
http://www.ibm.com/networking/support.
Priority Packet prioritizes traffic based on priority filters. These are parameters you
assign to outgoing (transmit) packets. Using the Priority Filter wizard, you can set
up predefined or custom priority filters based on a node (MAC) address, Ethernet
type, or by various properties of the protocol and port. Priority Packet provides two
different methods for prioritizing traffic: IEEE 802.1p tagging and High Priority
Queue.
22 xSeries 345 Type 8670: Hardware Maintenance Manual and Troubleshooting Guide
Page 33
IEEE 802.1p is an IEEE standard for tagging, or adding additional bytes of
information to packets with different priority levels. Packets are tagged with 4
additional bytes, which increase the packet size and indicate a priority level. When
you send these packets out on the network, the higher priority packets are
transferred first. Priority Packet tagging (also known as Traffic Class Expediting)
enables the Ethernet controller to work with other elements of the network (such as
switches and routers) to deliver priority packets first. You can assign specific priority
levels from 0 (low) to 7 (high).
You can assign values to packets based on their priorities when you use the IEEE
802.1p standard for packet tagging. This method requires a network infrastructure
that supports packet tagging. The routing devices receiving and transferring these
packets on the network must support 802.1p for tagging to be effective.
After you set up the priority filter in Priority Packet, you must start PROSet, click the
Advanced tab, and select QoS Packet Tagging from the list.
Note: IEEE 802.1p tagging increases the size of the packets it tags. Some hubs
and switches will not recognize the larger packets and will drop them. Check
the hub or switch documentation to see if they support 802.1p. (You can
configure the switch to strip the tags from the packets and send it on to the
next destination as normal traffic.) If these devices do not support 802.1p or
if you are not sure, use High Priority Queue (HPQ) to prioritize network
traffic.
The requirements for effectively using IEEE 802.1p tagging are:
v The other devices receiving and routing 802.1p tagged packets must support
802.1p.
v The adapters on these devices must support 802.1p. The Ethernet controller in
the server, all IBM 10/100 Ethernet Security Adapters, and IBM 10/100 Ethernet
Server Adapters support 802.1p.
v The adapter cannot be assigned to an adapter team.
v If you are setting up VLANs and packet tagging on the same adapter, you must
start PROSet, click the Advanced tab, and select QoS Packet Tagging from the
list.
If the network infrastructure devices do not support IEEE 802.1p or you are not
sure, you can still define filters and send packets as high priority. Although High
Priority Queue (HPQ) does not provide the precise priority levels of 802.1p tagging,
it does assign traffic as either high or low priority and sends high priority packets
first. Therefore, if there are multiple applications on a system sending packets, the
packets from the application with a filter are sent out first. HPQ does not change
network routing, nor does it add any information to the packets.
To assign HPQ, you can specify it using Priority Packet mode when you create or
assign a filter.
To effectively use HPQ, the adapter cannot be assigned to an adapter team.
Virtual LAN mode
A virtual LAN (VLAN) is a logical grouping of network devices put together as a
LAN, regardless of their physical grouping or collision domains. Using VLANs
increases network performance and improves network security.
Chapter 2. Configuring your server 23
Page 34
VLANs offer you the ability to group users and devices together into logical
workgroups. This can simplify network administration when connecting clients to
servers that are dispersed geographically across a building, campus, or enterprise
network.
Typically, VLANs are configured at the switch and any computer can be a member
of one VLAN per installed network adapter. The Ethernet controller supersedes this
by communicating directly with the switch, enabling multiple VLANs on a single
network adapter (up to 64 VLANs).
When you set up VLAN membership, the Ethernet controller must be attached to a
switch that has VLAN capability. You also need to use Windows 2000, Windows
®
4.0 or later, or Novell NetWare 4.1x or later.
NT
Notes:
1. Windows NT versions prior to 4.0 do not support VLANs.
2. VLANs require Windows NT 4.0 with Service Pack 3.0 and the network driver
interface specifications (NDIS) driver hotfix from Microsoft.
3. In Windows NT, VLANS cannot be implemented on controllers that have been
configured for teaming options. Netware can support teaming options and
VLANS on the same adapters.
Complete the following steps to join a VLAN from Windows NT 4.0:
1. Create a VLAN on the switch. Use the parameters you assign there to join the
VLAN from the server. See the switch documentation for more information.
2. Double-click the Start Proset icon in the Control Panel window.
3. On the Adapters page, right click on the adapter that you want to be on the
VLAN.
4. In IBMSet, click Add VLAN for the first adapter or click Join VLAN for
remaining adapters. Note that VLANs cannot be assigned to adapters that are
already defined to have an adapter teaming option.
5. Type the VLAN ID and VLAN name. The VLAN ID must match the VLAN ID of
the switch. The VLAN name is for information only and does not need to match
the name on the switch.
6. Repeat steps 3 through 5 for each VLAN you want the server to join. The
VLANs you add are listed on the Adapters page.
7. Click Close and restart the server.

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 157 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 101.
4. If the computer stops and no error is displayed, go to “Undetermined problems”
on page 111.
5. For power supply problems, see “Power-supply LED errors” on page 100.

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 Chapter 2, “Configuring your server”, on page 9 for more information.

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
Text messages
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 88).
iii is the three-digit device ID. (These codes are for trained service
personnel; see “Diagnostic error codes” on page 88).
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.
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.

Starting the diagnostic programs
Complete the following steps to start the diagnostic programs:
1. Turn on the server and watch the screen.
Note: To run the diagnostic programs, you must start the server with the
highest level password that is set. That is, if an administrator password is
set, you must enter the administrator password, not the power-on
password, to run the diagnostic programs.
2. When the message F2 for Diagnostics appears, press F2.
3. Type the appropriate password; then, press Enter.
4. Select either Extended or Basic from the top of the screen.
5. When the Diagnostic Programs screen appears, select the test you want to run
from the list that appears; then, follow the instructions on the screen.

is reported during the diagnostic test, such
as when a device driver is not found.
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.
30 xSeries 345 Type 8670: Hardware Maintenance Manual and Troubleshooting Guide
Page 41
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 27.
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 88.
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 on the front of the server is on, one or more LEDs inside
the server or on the power supply will be on. Your server has LEDs to help you
identify problems with some server components. These LEDs are part of the Light
Path Diagnostics feature built into the server. By following the path of lights, you
can quickly identify the type of system error that occurred.
Your server is designed so that any LEDs that are illuminated remain illuminated
when the server shuts down as long as the ac power source is good and the power
supply can supply +5 V dc current to the server. This feature helps you isolate the
problem if an error causes the server to shut down. See “Light Path Diagnostics
table” on page 34.
Power supply LEDs
The ac and dc power LEDs on the power supply provide status information about
the power supply. The following illustration shows the location of the ac and dc

v The electrical cord is properly connected to the server.
v The electrical outlet functions properly.
2. Disconnect the ribbon cable from connector J25 on the system board. If
the AC power LED comes on, see “Undetermined problems” on
page 111.
3. The power supply has failed.
Action: Replace the power supply.
Light Path Diagnostics
If the system error LED 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 illuminated when the server shuts
down, as long as the power supply is operating properly. This feature helps you to
isolate the problem even if an error causes the server to shut down.
Diagnostic panel LEDs
The following illustration shows the LEDs on the diagnostics panel inside the server.

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 flashing from the first error, it will not mask additional errors.
Light Path Diagnostics table
The System error LED on the front of the server is lit when certain system errors
occur. If the System error LED on your server is lit, check to see which of the LEDs

flash diskette.
1. Move the microprocessor in socket 1 to socket 2, and
move the microprocessor in socket 2 to socket 1.
2. Ensure that both microprocessors are of the same type,
with the same core frequency and the same L2 size.
3. Ensure that both VRMs are of the same type.
4. Ensure that both VRMs are supported in your server
model.
5. If a microprocessor is missing from socket 1, install a
microprocessor in socket 1.

Note: You can obtain a BIOS flash diskette from one of the following sources:
v Use the ServerGuide Setup and Installation CD 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.
The flash memory of your server contains a protected area that cannot be
overwritten. The recovery boot block is a section of code in this protected area that
enables the server to start up and to read a flash diskette. The flash utility recovers
the system BIOS code from the BIOS recovery files on the diskette.

Power checkout
Power problems can be difficult to solve. For example, a short circuit can exist
anywhere on any of the power distribution buses. Usually a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
A general procedure for troubleshooting power problems is as follows:
1. Turn off the server and disconnect all ac power cords.
2. Check for loose cables in the power subsystem. Also check for short circuits, for
example, if there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all
internal and external devices until the server is at the minimum configuration
required to start the server (see “Minimum operating requirements” on page
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 100). For specific problems, see “Power-supply LED
errors” on page 100.
Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the 10/100/1000 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the network, check the following
conditions:
v Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem remains, try a different cable.
If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,
you must use Category 5 or higher cabling.
v Determine whether the hub supports auto-negotiation. If it does not, try
configuring the integrated Ethernet controller manually to match the speed and
duplex mode of the hub.
v Check the Ethernet controller LEDs (on the operator information panel, on the
rear of the server, or both, depending on model; see “Server controls and
indicators” on page 4).
These LEDs indicate whether a problem exists with the connector, cable, or hub.
– The Ethernet transmit/receive activity LED 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 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.
38 xSeries 345 Type 8670: Hardware Maintenance Manual and Troubleshooting Guide
Page 49
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).

assigned to another device in the Configuration/Setup Utility program.
Although interrupt sharing is allowed for PCI devices, some devices do not function well
when they share an interrupt with a dissimilar PCI device. Try changing the IRQ
assigned to the Ethernet controller or the other device. For example, for NetWare
Versions 3 and 4, it is recommended that disk controllers not share interrupts with LAN
controllers.
v Make sure that you are using the most recent device driver available from the World
Wide Web.
v Run the network diagnostic program.
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 Run diagnostics on the LEDs.
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.
v Run diagnostics on the LEDs.
Check the following:
v Make sure that you are using Category 5 or higher cabling when operating the server at
100 Mbps or at 1000 Mbps.
v Make sure that the cables do not run close to noise-inducing sources like fluorescent
lights.

option-removal instructions are provided in case you need to remove one option to
install another.
Before you begin
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 121.
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
hot-plug Universal Serial Bus (USB) devices (if these devices are supported).
v The orange color on components and labels in your server identifies hot-swap or
hot-plug components. You can install or remove hot-swap and hot-plug
components while the server is running, provided that your server 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

Page 52
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 server. To
avoid damage, keep static-sensitive devices in their static-protective packages until
you are ready to install them.
To reduce the possibility of 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
static-protective package. Do not place the device on the server cover or on a
metal table.
v Take additional care when handling devices during cold weather because heating
reduces indoor humidity and increases static electricity.

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 You can install only low-profile adapters in slots 1 and 2.
v You can install standard full-length adapters, with the adapter guides removed
from the adapters, in slots 3 and 4.
v You can install only a half-length adapter in slot 5.
v The ServeRAID-5i controller can be installed only in PCI slot 2. The low-profile
2-U bracket that comes with the controller is required to install the controller.
v The ServeRAID-4LX Ultra160 SCSI controller can be installed in PCI slots 3, 4 or
5 of xSeries 345 models with a 400 MHz front-side bus microprocessor, but only
in PCI slots 3 or 4 of xSeries 345 models with a 533 MHz front-side bus
microprocessor.
v The optional IBM Remote Supervisor Adapter can be installed only in PCI slot 5.
Use the ribbon cable that comes with the adapter to connect the adapter to the
system management connector on the PCI riser-card.
v Your server supports 5.0 V and universal PCI adapters on the 32-bit PCI slot 5;
your server supports only 3.3 V and universal PCI adapters in the 64-bit
PCI/PCI-X slot 3 and 4.
v The PCI bus configuration is:
– Non-hot-plug, 64-bit PCI-X slots 1 through 2 (PCI bus A, 100 MHz)
– Non-hot-plug, 64-bit PCI-X slots 3 through 4 (PCI bus B, 133 MHz)
– Non-hot-plug, 32-bit PCI slot 5 (PCI bus C, 33 MHz)
v The system scans PCI and PCI-X slots 1 through 5 to assign system resources;
then the system starts (boots) the system devices in the following order, if you
have not changed the default boot precedence: integrated Ethernet controller,
integrated SCSI controller, and then PCI and PCI-X slots 5, 3, 4, 1, and 2.
Notes:
1. Some models come with the ServeRAID-5i controller preinstalled.
2. If the ServeRAID-5i controller is installed, it takes control of the integrated
SCSI controller with RAID capabilities and operates at 66 MHz. The
ServeRAID-5i controller can be installed only in slot 2.
3. 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 Chapter 2, “Configuring your server”, on page 9 for details about
using the Configuration/Setup Utility program.

Installing a ServeRAID-5i controller
You can install an optional RAID controller in your server to control the internal
hot-swap hard disk drives, for example, to enable you to configure the internal
hot-swap hard disk drives into disk arrays. You can also cable a RAID adapter to
external hard disk drives. See your RAID controller option documentation for
complete instructions on installing a RAID controller in your server and for additional
information on RAID controllers.
Notes:
1. No rerouting of the internal SCSI cable is required if you are installing the
ServeRAID-5i controller. The ServeRAID-5i controller uses the SCSI connector
on the system board for output.
2. The ServeRAID-5i controller can be installed only in PCI-X slot 2. Slot 2 is the
only PCI-X slot that supports the ServeRAID-5i controller requirements.
3. Connections made to external SCSI devices will be asynchronous.
4. Some models come with the ServeRAID-5i controller preinstalled.
Complete the following steps to install a ServeRAID-5i controller:
1. Review the information in “Safety information” on page 121 and “Handling
static-sensitive devices” on page 42.
2. Turn off the server and peripheral devices and disconnect all power cords and
external cables (see “Turning off the server” on page 7); then, remove the cover
(see “Removing the cover and bezel” on page 50).
3. Open the adapter retainer and slide the slot 2 expansion-slot cover out of the
server. Store it in a safe place for future use.
56 xSeries 345 Type 8670: Hardware Maintenance Manual and Troubleshooting Guide
Page 67
Attention: Expansion-slot covers must be installed on all empty slots. This
maintains the electronic emissions characteristics of the system and ensures
proper cooling of system components.
4. Install the low profile 2-U bracket on the adapter:
a. Remove the adapter from the static-protective package. Set the adapter
down on a nonconductive, static-protected surface (place it component side
up).
Attention: Avoid touching the components and gold-edge connectors on
the adapter.
b. Remove the 3-U bracket from the adapter and replace it with the 2-U low
profile bracket that comes with the RAID controller option. See the
documentation that comes with your RAID controller option for instructions.
5. Install the adapter:
a. Carefully grasp the adapter by its top edge or upper corners, and align it
with the expansion slot on the system board.
b. Press the adapter firmly into the expansion slot and close the adapter
retainer.
Attention: When you install an adapter in the server, be sure that it is
completely and correctly seated in the connector. Incomplete insertion might
cause damage to the system board or the adapter.
6. If you have other options to install or remove, do so now; otherwise, go to
“Installing the server cover and bezel” on page 71.
Installing a hot-swap drive
Your server supports six 1-inch (26 mm) slim 3.5-inch low voltage differential (LVD)
hard disk drives.
Each hot-swap drive has two indicator LEDs. If the amber hard disk drive status
LED is lit continuously, that drive is faulty and requires replacement. When the hard
disk status LED indicates a drive fault, you can replace a hot-swap drive without
turning off the server.
The following illustration shows how to install a hot-swap hard disk drive.
Drive-tray assembly
Drive handle
Complete the following steps to install a drive in a hot-swap bay.
Filler panel
Chapter 4. Customer replaceable units 57
Page 68
Notes:
1. All hot-swap drives being used in the server should have the same data transfer
rate. Mixing hard disk drives with different data transfer rates will cause all
drives to operate at the lower speed.
2. The SCSI ID assigned to each bay is printed on the bezel.
Attention: To maintain proper system cooling, do not operate the server for more
than 10 minutes without either a drive or a filler panel installed in each bay.
1. Review the information in “Safety information” on page 121, and “Before you
begin” on page 41.
2. Remove the filler panel from one of the empty hot-swap bays by inserting your
finger into the depression at the left side of the filler panel and pulling it away
from the server.
3. Install the hard disk drive in the hot-swap bay:
a. Ensure that the tray handle is open (that is, perpendicular to the drive).
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 LED 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
individual 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 you have a RAID configuration on your server using the integrated
SCSI controller with RAID capabilities, or if your server has a RAID
adapter installed, you might need to reconfigure your disk arrays after
installing hard disk drives. See the RAID documentation on the IBM
xSeries Documentation CD for information about RAID adapters.
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 double data
rate (DDR) dual inline memory modules (DIMMs).
Attention: Install only 2.5 V, 184-pin, double-data-rate (DDR), registered
synchronous dynamic random-access memory (SDRAM) with error correcting code
(ECC) DIMMs. These DIMMs must be compatible with the latest PC2100 (CL2.5)
specification, and downward compatible with PC1600 (CL2) SDRAM Registered
DIMM specification, which is available from http://www.jedec.org/ on the World Wide
Web. For a list of supported options for your server, go to
http://www.ibm.com/us/compat/ on the World Wide Web.
Notes:
1. The system board contains four DIMM connectors and supports two-way
memory interleaving.
2. The DIMM options available for your server are 256 MB, 512 MB, and 1 GB.
Your server supports a minimum of 512 MB and a maximum of 4 GB of
system memory.
58 xSeries 345 Type 8670: Hardware Maintenance Manual and Troubleshooting Guide
Page 69
3. The amount of usable memory will be reduced depending on the system
configuration. The BIOS will display the total amount of installed memory and
the amount of configured memory.
4. Your server supports a minimum of two 256 MB DIMMs (for a total of 512 MB)
installed in the DIMM 1 and DIMM 2 memory connectors (J1 and J2,
respectively). When you install additional DIMMs, install them in pairs, with the
next pair in DIMM connectors 3 and 4 (J3 and J4).
5. Both DIMMs in a pair must be the same size, speed, type, and technology. You
can mix compatible DIMMs from various manufacturers.
6. The second pair of DIMMs do not have to be the same size, speed, type, and
technology as the first pair.
7. Install only 100 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 (and downward compatible with PC1600) SDRAM Registered DIMM
specification, which is available from http://www.jedec.org/ on the World Wide
Web. 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 technology, if the DIMMs are all of the type 4x and
are larger than 128 MB.
9. Save new configuration information only if you replace a faulty DIMM that was
marked as Disabled in the Configuration/Setup Utility program Memory
Settings menu. In this case, re-enable the memory row in the
Configuration/Setup Utility program or reload the default memory settings. See
Chapter 2, “Configuring your server”, on page 9 for more information.
Install the DIMMs in the order shown in the following table:

Before you begin, read the documentation that comes with your option.
Complete the following steps to install a DIMM.
1. Review the information in “Safety information” on page 121, “Before you begin”
on page 41, and “Handling static-sensitive devices” on page 42.
2. Turn off the server and disconnect all power cords and external cables (see
“Turning off the server” on page 7); then, remove the server cover (see
“Removing the cover and bezel” on page 50).
3. Locate the DIMM connectors on the system board. Determine the connectors
into which you will install the DIMMs.
4. 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.
5. To install the DIMM, 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 position.
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.
6. If you have other options to install or remove, do so now; otherwise, go to
“Installing the server cover and bezel” on page 71.
Installing an additional microprocessor
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
between the microprocessors. If your server comes with one microprocessor, you
can install a second microprocessor.
Installation guidelines:
v Thoroughly review the documentation that comes with the microprocessor, so
that you can determine whether you need to update the server BIOS code. You
can download the latest level of BIOS code and many other code updates for

Ultra320 SCSI controller system-board connectors
Your server has an integrated dual channel small computer system interface (SCSI)
controller with RAID capabilities. This controller supports two independent Ultra320
SCSI channels: one external and one internal. Each channel supports up to 15
SCSI devices. You can use the external LVD SCSI channel connector on the rear of
your server to connect different types of SCSI devices, such as drives or printers.
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
The server comes with one SCSI cable, which connects the internal connector on
the system board to the standard hot-swap-drive backplane. If you plan to attach
external SCSI devices, you must order additional cables. To select and order the
correct cables for use with external devices, contact your IBM reseller or IBM
marketing representative.
SCSI cabling requirements
For information about the maximum length of SCSI cable, go to the American
National Standards Institute (ANSI) SCSI standards on the ANSI Web site at
http://www.ansi.org/ 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 9 lists the SCSI IDs for the hard disk drives and
backplanes that are connected to one channel.

Chapter 6. Symptom-to-FRU index
This index supports xSeries 345 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 first column of the two-column tables in this index lists error codes or
messages, and the second column lists one or more suggested actions or FRUs to
replace. Take the action (or replace the FRU) suggested first in the list of the
second column, then try the server again to see if the problem has been corrected.
Note: Try reseating a suspected component or reconnecting a cable before
replacing the component.
The POST BIOS code displays POST error codes and messages on the screen.
Beep symptoms
Beep symptoms are short tones or a series of short tones separated by pauses
(intervals without sound). See the examples in the following table.
Beeps Description
