Before You Begin
Before you begin to install options in your server, read the f ollowing information:
• Become familiar with the information provided in “Handling Static-sensitive Devices” and in
the “Safety Addendum”. These guidelines will help you make changes t o disk drives.
• 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.
• Back up all important data before you make changes to disk drives.
• For a list of supported options for the xSeries 343, refer to http://www.ibm.com/pc/compat on
the World Wide Web.
Handling Static-sensitive Devices
Attention: Static electricity can damage electronic devices and your system. To avoid damage,
keep static-sensitive devices in their static-protective package until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave the device where others can handle and possibly damage the device.
• While the device is still in its anti-static package, touch it to an unpainted metal part of the
system unit for at least two seconds. (This drains static electricity from the package and from
your body.)
• Remove the device from its package and install it directly into your system unit 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 your system unit cover or on a metal table.
• Take additional care when handling devices during cold weather because heating reduces
indoor humidity and increases static electricity.

D Power switch Toggles the system power on/off.
E Reset switch Reboots and initializes the system.
Front Panel Alarm LEDs and Relays
F Critical (amber) When continuously lit, indicates the presence of a Critical System Fault. A
critical system fault is an error or event that is detected by the system with a
fatal impact to the system. In this case, the system cannot continue to operate.
An example could be the loss of a large section of memory or other corruption
that renders the system not operational. Additionally, the front panel critical
alarm relay will engage.
G Major (amber) When continuously lit, indicates the presence of a Major System Fault. A major
system fault is an error or event that is detected by the system that has
discernable impact to system operation. In this case, the system can continue
to operate but in a “degraded” fashion (reduced performance or loss of
non-fatal feature reduction). An example could be the loss of one of two
mirrored disks. Additionally, the front panel major alarm relay will engage.
H Minor (amber) When continuously lit, indicates the presence of a Minor System Fault. A minor
system fault is an error or event that is detected by the system but has little
impact to actual system operation. An example would be a correctable
ECC error. Additionally, the front panel minor alarm relay will engage.

Processor
The server board accommodates one or two Pentium III processors up to 1-26 GHz with 512k cache
in the FC-PGA2 package.
Memory
The system board contains six 168-pin DIMM slots each supporting 72-bit ECC (64-bit main
memory plus ECC) registered SDRAM DIMMs (PC-133 compatible). You may install a minimum
of 128 MB (64 MB x 2) and as much as 6 GB.
Note
Use DIMMs that have been tested for compatibility with the server board.
Contact your sales representative or dealer for a current list of approved
memory modules.
PCI Riser Slots
The server board has two PCI r iser slots: a 5 V riser that supports 64-bit/33 MHz riser cards and a
3.3 V riser that supports 64-bit/66 MHz riser cards.
• Bus speed up to 66 MHz
• 32 bit memory addressing
• 5 V/3.3 V signaling environment
• Burst transfers of up to 512 Mbps
• 8, 16, 32, or 64-bit data transfers
• Plug and Play ready
• Parity enabled
Video
The server board uses an ATI RAGE XL PCI graphics accelerator with 8 MB of video SDRAM
that supports all standard IBM VGA modes. The embedded SVGA video subsystem supports:
• Pixel resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D
• CRT and LCD monitors up to 100 Hz vertical refresh rate
The server board supports disabling of the onboard video through the BIOS setup menu or when a
plug in video card i s installed in any of t he PCI slots.
SCSI Controller
The SCSI version of the server board includes an embedded Adaptec AIC-7899W controller
providing dual Ultra160 Low Voltage Differential (LVD) SCSI channels.
The SCSI bus is terminated on the server board with active terminators that cannot be disabled.
The onboard device must always be at one end of the bus. The device at the other end of the cable
is terminated with the active terminator on the SCSI cable installed in the system.
Chassis Description 15
Network Controller
Note
To ensure EMC product regulation compliance for intra-building lighting
surges, the system must only be used with shielded LAN cables that are
grounded at both ends.
The server board uses two Intel 82550PM Fast Ethernet Controllers and supports two
10Base-T/100Base-TX network subsystems.
On the server board, NIC 1 can be used as both a network interface and server management
interface.
NIC Connector and Status LEDs
The 82550 controller drives LEDs on the network interface connector that indicate link/activity on
the LAN and 10- or 100-Mbps operation. The green LED indicates network connection when on
and TX/RX activity when blinking. The yellow LED indicates 100-Mbps operation when lit.
Network Teaming Features
Note
Using both on-board NICs in a team does not allow the use of NIC 1 for
server management access. To support both network teaming features and
server management features, a third NIC must be added and teamed to NIC 2.
The network controller provides several options for increasing throughput and fault tolerance when
running Linux®:
• Adapter Fault Tolerance (AFT) - provides automatic redundancy for your adapter. If the
primary adapter fails, the secondary takes over. AFT works with any hub or switch.
• Adaptive Load Balancing (ALB) - creates a team of 2 - 6 adapters t o increase transmission
throughput. Also includes AFT. Works with any 10Base-TX or 100Base-TX switch.
• Fast EtherChannel (FEC) or Intel Link Aggregation - cr eates a team of up to 6 adapters to
increase transmission and reception throughput. Also includes AFT. Requires a FEC-enabled
switch.
To set up an option, read the instructions in the Linux RH 7.1 readme files.
Adapter Fault Tolerance
Adapter Fault Tolerance (AFT) is a simple, effective, and fail-safe approach to increase the
reliability of server connections. AFT gives you the ability to set up link recovery to the server
adapter in case of a cable, port, or network interface card failure. By assigning two server adapters
as a team, AFT enables you to maintain uninterrupted network performance.
AFT is implemented with two server adapters: a primary adapter and a backup, or secondary,
adapter. During normal operation, the backup will have transmit disabled. If the link to the
primary adapter fails, the link to the backup adapter automatically takes over.
16 xSeries 343 Hardware Maintenance Manual
Preferred Primary Adapter
With multiple adapters installed, you can specify one as the Preferred Primary adapter. For
example if you have a server with a PRO/1000 server adapter as the primary adapter and a
PRO/100+ adapter as the secondary, you could configure the PRO/1000 server adapter to be the
preferred primary. In this scenario, if the PRO/1000 server adapter fails, the PRO/100+ will take
over. Then when the PRO/1000 server adapter is r eplaced, it will automatically revert to being the
primary adapter in the team.
If a Preferred Primary is not selected, PROSet will attempt to select the best adapter, based on
adapter model and speed.
Mixed Adapter Teaming
AFT supports up to six server adapters per team, in any mix.
Adaptive Load Balancing
Adaptive Load Balancing (ALB) is a simple and efficient way t o increase your server's transmit
throughput. With ALB you group server adapters in teams to provide an increased transmit rate
(up to 8 Gbps) using a maximum of eight adapters. The ALB software continuously analyzes
transmit loading on each adapter and balances the r ate across the adapters as needed. Adapter
teams configured for ALB also provide the benefits of AFT. Receive rates remain at 100 Mbps or
1 Gbps depending on the primary adapter’s capability.
To use ALB, you must have 2-6 server adapters installed in your server or workstation and linked
to the same network switch.
Cisco Fast EtherChannel
Fast EtherChannel (FEC) is a performance technology developed by Cisco to increase your server's
throughput. Unlike ALB, FEC can be configured to increase both transmission and reception
channels between your server and switch. FEC works only with FEC-enabled switches, such as the
Catalyst 5000 series. With FEC, as you add adapters to your server, you can group them in teams
to provide up to 18 Gbps at full duplex, with a maximum of 6 server adapters. The FEC software
continuously analyzes loading on each adapter and balances network traffic across the adapters as
needed. Adapter teams configured for FEC also provide the benefits of AFT.
To use FEC, you must have 2, 4, or 6 server adapters plus use of both onboard NIC adapters
installed in your server and linked to the same FEC-enabled Cisco switch.
Keyboard and Mouse
The keyboard controller is PS/2-compatible. If specified through the System Setup Utility (SSU),
the server may be locked automatically if there is no keyboard or mouse activity for a predefined
length of time. Once the inactivity (lockout) timer has expired, the keyboard and mouse do not
respond until the previously stored password is entered. If a mouse is required, you can either
connect a USB mouse to a USB port or a PS/2 mouse to the PS/2 port using the “Y”-splitter cable.
Chassis Description 17
RJ45 Serial Port
The rear RJ45 serial port is a fully functional COM port that supports any standard serial device
and provides support for serial concentrators, which typically support RJ45 serial connectors. For
server applications that use a serial concentrator to access the server management features of the
baseboard, a standard 8-pin CAT-5 cable from the serial concentrator is plugged directly into the
rear RJ45 serial port. The 8 pins of the RJ45 connector can be configured to match either of two
pin-out standards used by serial port concentrators. T o accommodate either standard, the
J6A2 jumper block located directly behind the rear RJ45 serial port must be jumpered appropriately
according to which standard is desired.
Note
The RJ45 serial port’s default configuration is DSR. For serial concentrators
requiring a DCD signal, configure the jumper block as shown in Figure 39.
For serial concentrators that require a DCD signal, configure the J6A2 jumper block as shown in
Figure 39.
For those server applications requiring a DB9 serial connector, use an 8-pin RJ45-to-DB9 adapter.
Table 6 defines the pin-out required for the adapter to provide RS232 support.

Note
The RJ45-to-DB9 adapter should match the configuration of the serial device
used. One of two pin-out configurations are used depending on whether the
serial device requires a DSR or DCD signal. The final adapter configuration
should also match the desired pin-out of the RJ45 connector, as it can also be
configured to support either DSR or DCD.
ACPI
The server board supports the Advanced Configuration and Power Interface (ACPI) as defined by
the ACPI 1.0 and PC97 specifications. An ACPI aware operating system can put the system into a
state where the hard drives spin down, the system fans stop, and all processing is halted. However,
the power supply will still be on and the processors will still be dissipating some power, so the
power supply fans will still run.
18 xSeries 343 Hardware Maintenance Manual
The server board supports sleep states s0, s1, s4, and s5:
• s0: Normal running state.
• s1: Processor sleep state. No context will be lost in this state and the processor caches will
maintain coherency.
• s4: Hibernate or Save to Disk: The memory and machine state are saved to disk. Pressing the
power button or other wakeup event will restore the system state from the disk and resume
normal operation. This assumes that no hardware changes have been made to the system while
it was off.
• s5: Soft off: Only the RTC section of the CSB and the BMC are running in this state. No
context is saved by the OS or hardware.
Note
The system is off only when the DC power cable is disconnected.
Security
Software Locks
The BIOS Setup and the System Setup Utility (SSU) provide a number of security features to
prevent unauthorized or accidental access to the system. Once the security measures are enabled,
you can access the system only after you enter the correct password(s). For example:
• Enable the keyboard lockout timer s o that the server requires a password to reactivate the
keyboard and mouse after a specified time out period1 to 120 minutes.
• Set and enable a supervisor password.
• Set and enable a user password.
• Set secure mode to prevent keyboard or mouse input and to prevent use of the front panel reset
and power switches.
• Activate a hot key combination to enter secure mode quickly.
• Disable writing to the diskette drive when secure mode is set.
• Disable access to the boot sector of the operating system hard disk drive.
Using Passwords
You can set either the user password, the supervisor password, or both passwords.
If only the user password is set, you:
• Must enter the user password to enter BIOS Setup or the SSU.
• Must enter the user password to boot the server if Password on Boot is enabled in either the
BIOS Setup or SSU.
• Must enter the user password to exit secure mode.
If only the supervisor password is set, you:
• Must enter the supervisor password to enter BIOS Setup or the SSU.
• Must enter the supervisor password to boot the server if Password on Boot is enabled in either
the BIOS Setup or SSU.
• Must enter the supervisor password t o exit secure mode.
Chassis Description 19
If both passwords are set, you:
• May enter the user password to enter BIOS Setup or the SSU. However, you will not be able to
change many of the options.
• Must enter the supervisor password if you want to enter BIOS Setup or the SSU and have
access to all of the options.
• May enter either password to boot the server if Password on Boot is enabled in either the BIOS
Setup or SSU.
• May enter either password to exit secure mode.
Secure Mode
Configure and enable the secure boot mode by using the SSU. When secure mode is in effect:
• You can boot the server and the operating system will run, but you must enter the user
password to use the keyboard or mouse.
• You cannot turn off system power or reset the server from the front panel switches.
• Secure mode has no effect on functions enabled via remote server management or power
control via the watchdog timer.
Taking the server out of secure mode does not change the s tate of system power. That is, if you
press and release the power switch while secure mode is in effect, the system will not be powered
off when secure mode is later removed. However, if the front panel power switch remains
depressed when secure mode is removed, the server will be powered off.
Summary of Software Security Features
Table 7 lists the software security features and describes what protection each offers. In general, to
enable or set the features listed here, you must run the SSU and go to the Security Subsystem
Group, menu. The table also refers to other SSU menus and to the Setup utility.
Table 7. Software Security Features
Feature Description
Secure mode How to enter secure mode:
Setting and enabling passwords automatically places the system in secure mode.
If you set a hot-key combination (through Setup), you can secure the system
simply by pressing the key combination. This means you do not have to wait for
the inactivity time-out period.
When the system is in secure mode:
The server can boot and run the operating system, but mouse and keyboard input
is not accepted until the user password is entered.
At boot time, if a CD is detected in the CD-ROM drive or a diskette in drive A, the
system prompts for a password. When the password is entered, the server boots
from CD or diskette and disables the secure mode.
If there is no CD in the CD-ROM drive or diskette in drive A, the server boots from
drive C and automatically goes into secure mode. All enabled secur e mode
features go into effect at boot time.
To leave secure mode: Enter the correct password(s).

Chassis Description 23
Introduction
The xSeries343 server system uses a -48 to -60 VDC input switching power subsystem, which
provides up to 350 Watts with -48 to -60 VDC input and with current and remote sense regulation.
The power subsystem consists of one or two 350-Watt power supply modules. A system with two
modules forms a redundant, hot-swappable (1+1) power subsystem.
Interface Requirements
DC Input
The DC power source may produce hazardous voltage levels exceeding -60 VDC and high energy
levels above 240VA that may cause electric shock or burns. All DC input connections should be
made only by a qualified service person only to prevent injury. All wiring terminals connected to
the DC input terminal block must be fully insulated with no exposed bare metal.
DC Output Connectors
The power subsystem DC power and control signals are interfaced to the server system via wire
harnesses when the power supply modules are inserted into the power subsystem enclosure. The
safety ground pin of the power supply module is the first pin to connect and the last to disconnect
when the module is being inserted or removed from the power subsystem housing. In addition to
the 5 V Standby, -12 V, +3.3 V, +5 V and +12 V DC outputs, the following signals and output pins
are included:
• +3.3 VDC remote sense
• +5 VDC remote sense
• +12 VDC remote sense
• Remote sense return
• Power Subsystem On (DC PWR enable)
• Power Good

Note: The maximum combined power of the 3.3 V and 5 V outputs is 150 W.
Peripheral Bay
The peripheral bay consists of the following two bays for removable media:
• Low profile media bay 1 – for a ½-inch Floppy drive
• Low profile media bay 2 – for a ½-inch CD-ROM drive
Hard Drive Tray
The hard drive tray supports two 3.5-inch x 1.0-inch Ultra160 SCSI hard disk drives (non-SCA).
The hard drive tray is designed to accept 15 K RPM (and below) hard drives t hat consume up to
18 Watts of power.
Chassis Description 25
Cooling Subsystem
The cooling subsystem contains a fan array (as shown in Figure 9) consisting of two 80 x 38 mm
fans and two 40 x 28 mm fans to cool the server board and other components. A fan failure is
indicated by one of the fault LEDs located on the front panel.
OM12820
Figure 9. Fan Array with Four System Fans Installed
Air flows through the bezel, over the peripheral bay and the hard drive tray, passes through the
fans, over the server board, and exhausts through the rear of the chassis.
Each fan provides a tachometer signal output to the server board to indicate a fan failure.
Ambient Temperature Control
The server board contains a pulse-width-modulation (PWM) circuit, that cycles the 12 VDC fan
voltage to provide quiet operation when system baseboard temperature is low, and there are no fan
failures. Under normal baseboard temperature conditions (less than 45 °C), the fan power circuit
supplies an effective fan voltage of 7.0 VDC. When the baseboard temperature exceeds 45 °C, the
fan control circuit ceases cycling and delivers 12 VDC. Following a baseboard temperature
excursion above 45 °C the fan voltage does not reenter PWM mode until the baseboard temperature
drops below 45 °C and all fans are operational.
The cooling subsystem’ design meets acoustic and thermal requirements at the lower fan speed
settings. At the higher fan speed settings, thermal requirements are met for the maximum ambient
temperatures but acoustic requirements are not met.
26 xSeries 343 Hardware Maintenance Manual
Server Management Summary
The server board’s server management architecture features a board management controller (BMC),
which autonomously monitors server status and provides the interface to server management
control functions. The BMC is responsible for controlling system power, resets, monitoring
voltages, temperatures, fans, and communicating with secondary controllers on its Intelligent
Platform Management Bus (IPMB).
The functions of each controller are summarized in the following sections.
Server Board Management Controller
The BMC on the server board provides server management monitoring capabilities. Associated
with the BMC is a flash memory that holds the operational code, sensor data records (SDR), and
system event log (SEL). A serial EEPROM holds the BMC configuration defaults and field
replaceable unit (FRU) information. The BMC supports the following:
• Server board voltage monitoring
• Fan failure detection
• Fan speed control
• Processor voltage monitoring
• Processor presence detection
• Processor internal error (IERR) monitoring
• Fault resilient booting (FRB)
• Processor disable control

Using BIOS Setup
This section describes the BIOS Setup options. Use Setup t o change the server configuration
defaults. You can run Setup with or without an operating system being present. Setup stores most
of the configuration values in battery backed CMOS; the rest of the values are stored in flash
memory. The values take effect when you boot the server. POST uses these values to configure
the hardware; if the values a nd the actual hardware do not agree, POST generates an error message.
You must then run Setup to specify the correct configuration.
Recording Your Setup Settings
If the default values ever need to be restored (after a CMOS clear, for example), you must run
Setup again. Referring to the worksheets could make your task easier.
If You Cannot Access Setup
If the diskette drive is incorrectly configured so that you cannot access it to run a utility from a
diskette, you may need to clear CMOS memory. You will need to open the server, change a jumper
setting, use Setup to check and set diskette drive options, and change the jumper back.
Starting Setup
After rebooting, you will see this prompt:
Press <F2> to enter SETUP
Note
If the BIOS setup option “POST Diagnostic Screen” is enabled (Default), you will not see the
message “Press <F2> to enter SETUP”. This message is hidden by the Manufacturer’s Splash
screen. To see the message, press the <ESC> key while the splash screen is displayed. This will
temporarily disable the splash screen allowing you to see the message.
If CMOS/NVRAM is corrupted, you will see other prompts but not the <F2> prompt:
Warning:cmos checksum invalid
Warning:cmos time and date not set
In this condition, the BIOS will load default values for CMOS and attempt to boot.

Try shutting down the system and booting up again. CMOS checksum errors
require that you enter Setup, check your settings, save your settings, and exit
Setup.
Configuration Software and Utilities 45
Recovering the BIOS
It is unlikely that anything will interrupt the BIOS upgrade; however, if an interruption occurs, the
BIOS could be damaged. The following steps explain how to recover t he BIOS if an upgrade fails.
Note
Because of the small amount of code available in the non-erasable boot block
area, there is no video support. You will not see anything on the screen
during the procedure. Monitor the procedure by listening to the speaker.
You must boot to DOS. The BIOS recovery diskette will not be created
Note
correctly under the DOS window of a Windows operating system.
1. Get the BIOS update file package from IBM iBL or http://www.ibm.com/pc/support.
2. A file called “crisis.zip” is one of the files included with each xSeries 343 BIOS release file
package. Unzip the “crisis.zip” file to a directory on your hard drive.
3. Format a blank diskette (the diskette should not be a bootable DOS diskette). Insert the diskette
into the diskette drive.
4. From the DOS, run the “crisdisk.bat” file from the directory you created on your hard drive.
Follow the instructions on the screen to create the BIOS recovery diskette.
The BIOS recovery diskette will not be created correctly under the DOS
window of a Windows operating system. You must boot to a DOS system to
create the BIOS recovery diskette.
5. Power off the xSeries 343 system, unplug/disconnect the power cord, and remove the chassis
panel.
6. Remove the spare jumper from pins 11-12 on jumper block 1J15 and install it on pins
9-10 (BIOS Recovery) of jumper block 1J15.
7. Insert the BIOS recovery diskette into the diskette drive.
8. Reinstall the chassis panel, plug-in/reconnect the power connection, and power-on the system.
9. The screen will remain blank while the BIOS Recovery is performed. A number of beeps will
occur during the BIOS update. The diskette drive access light will not turn off when the BIOS
recovery is completed. Allow four minutes for the BIOS recovery to complete. If a POST card
is installed in a PCI slot during the BIOS recovery, you can tell that the BIOS recovery is
complete when code “EC” is displayed. When the BIOS Recovery is complete, it is safe to
power off the system.
10. Power off the system, unplug/disconnect the power cord, and remove the chassis panel.
11. Remove the BIOS Recovery jumper from pins 9-10 and store the jumper on pins 11-12.

Using the System Setup Utility
The System Setup Utility (SSU) is on the Documentation and Resource CD shipped with the server
board. The SSU provides a graphical user interface (GUI) over an extensible framework for server
configuration. The SSU framework supports the following functions and capabilities:
• Allows viewing and clearing of the system’s critical event log
• Allows the viewing of the system management FRU information
• Allows the viewing of the system management SDR repository
What You Need to Do
The SSU may be run directly from the Documentation and Resource CD (by booting t he server
system to the CD and selecting “Utilities”) or from a set of DOS diskettes.
If you choose to run the SSU from a set of DOS diskettes, you must create the SSU diskettes from
the Documentation and Resource CD by booting to the CD and selecting “Create Diskettes.”
Alternatively, if you have a Windows 95 or Windows NT workstation, you can insert the CD into
that system and create diskettes from the “Utilities” menu of the graphical user interface.
If your diskette drive is disabled, or improperly configured, you must use the flash resident Setup
utility to enable it so that you can use the SSU. If necessary, you can disable the drive after you
exit the SSU. Information entered using the SSU overrides any entered using Setup.
Running the SSU from the CD
Running the ssu.bat file provided on the SSU media starts the SSU. If the server boots directly
from the SSU media, the ssu.bat file is automatically run. If it boots from a different media, the
SSU can be started manually or by another application. When the SSU starts in the local execution
mode (the default mode), the SSU accepts input from the keyboard and/or mouse. The SSU
presents a VGA based Graphical User Interface (GUI) on the primary monitor.
Configuration Software and Utilities 47
The SSU runs from writable, non-writable, removable, and non-removable media. If the SSU is
run from non-writable media, user preference settings (such as screen colors) cannot be saved.
The SSU supports the ROM-DOS V6.22 operating system. It may run on other
ROM-DOS-compatible operating systems but they are not supported. The SSU will not operate
from a “DOS box” running under an operating system such as Windows.
Running the SSU Remotely via an Emergency Management Card
Using graphical hardware redirection via the emergency management card 2, you can see the SSU
Console in VGA graphics mode, control the mouse, and control the keyboard from a local system
connected to a remote server by a network or modem.
The emergency management card 2 provides video memory, keyboard, and mouse redirection
support. Video memory and user input are sent to a remote location through either a modem or
Ethernet link and displayed by the Remote Control console. This solution requires an emergency
management card 2 card installed in the remote server and the Remote Control software available
on the local system. The SSU will execute exclusively on the remote server. Any files required for
the SSU to execute must be on the remote server.
Starting the SSU
SSU consists of a collection of task-oriented modules plugged into a common framework called the
Application Framework (AF). The Application Framework provides a launching point for
individual tasks and a location for setting customization information. The SSU requires the
availability of the AF.INI, AF.HLP, plus any .ADN files and their associated .HLP and .INI files.
1. After creating set of three SSU diskettes from the CD: Insert the first SSU diskette in drive
A, and press the reset button or <Ctrl+Alt+Del> to reboot your server from the diskette. Insert
the second diskette when prompted.
2. Directly from the Documentation and Resource CD: Insert the Documentation and Resource
CD into your CD ROM drive and press the reset button or <Ctrl-Alt-Del> to reboot. When
prompted to do so, press <F2> to enter BIOS Setup. From the Boot Menu, select the Boot
Device Priority option and then select CD-ROM as your primary boot device. Save those
settings and exit BIOS Setup. The server will boot from the CD-ROM and display a menu of
options. Follow the instructions in the menu to start the SSU.
3. When the SSU title appears on the screen, press <Enter> to continue.
4. The mouse driver loads if it is available; press <Enter> to continue.
5. This message appears:
Please wait while the Application Framework loads....
6. When the main window of the SSU appears, you can customize the user interface before
continuing.

FRU/SDR Load Utility
The Field Replacement Unit (FRU) and Sensor Data Record (SDR) Load Utility is a DOS-based
program used to update the server management subsystem’s product level FRU, SDR, and the SM
BIOS (SMB) nonvolatile storage components (EEPROMs). The load utility:
• Discovers the product configuration based on instructions in a master configuration file
• Displays the FRU information
• Updates the nonvolatile storage device (EEPROM) associated with the Baseboard Management
Controller (BMC) t hat holds the SDR and FRU area
• Updates the SMB area located in the BIOS nonvolatile storage device
• Generically handles FRU devices that may not be associated with the BMC
52 xSeries 343 Hardware Maintenance Manual
When to Run the FRU/SDR Load Utility
You should run the FRU/SDR Load Utility each time you upgrade or replace the hardware in your
server, excluding add-in boards, hard drives, and RAM. For example, when you upgrade your
processor or add a second power module to the 1+1 power supply.
Because the firmware must reload to properly initialize the sensors after programming, turn the
server off and unplug/disconnect the power cords from the server. Wait approximately 30 seconds,
and plug-in/reconnect the power cords.
What You Need to Do
The FRU/SDR Load Utility may be run directly from the Documentation and Resource CD or from
a diskette you create from the CD. It can be extracted from the CD by booting to the CD and
selecting “Make Diskettes” or by inserting the CD into a PC running Windows 95 or NT and
selecting the “Utilities” section.
Note
If your diskette drive is disabled, or improperly configured, you must use
BIOS Setup to enable it. If necessary, you can disable the drive after you are
done with the FRU/SDR utility.
How You Use the FRU/SDR Load Utility
This utility is compatible with ROM-DOS Version 6.22, MS-DOS Version 6.22, and later versions.
The utility accepts CFG, SDR and FRU load files. The executable file for the utility is frusdr.exe.
The utility requires the following supporting files:
• One or more .fru files describing the system’s field replaceable units
• A .cfg file describing the system configuration
• A .sdr file describing the sensors in the system
frusdr Is the name of the utility
/? Or /h Displays usage information
/d {smb, fru, sdr} Only displays requested area
/cfg filename.cfg Uses custom CFG file
/p Pause between blocks of data
Configuration Software and Utilities 53
Parsing the Command Line
The FRU/SDR Load Utility allows only one command line function at a time. A command line
function may consist of two parameters; for example: cfg filename.cfg. Any invalid parameters
result in displaying an error message and exiting the program. You can use either a slash (/) or a
minus sign (-) to specify command line options. The /p flag may be used in conjunction with any
of the other options.
Displaying Usage Information
When the utility is run with the /? or /h command line flags, the following message is displayed:
FRU & SDR Load Utility Version X.XX
Usage:FrusdrIs the name of the utility.
/? Or /hDisplays usage information.
/d {smb,fru,sdr}Only displays requested area.
/cfg filename.cfgUses custom CFG file.
/pPause between blocks of data.
Displaying a Given Area
When the utility is run with the /d SMB, /d FRU, or /d SDR command line flag, the indicated area
is displayed. Each area represents a sensor; one sensor for each instrumented device in the server.
If the given display function fails because of an inability to parse the data present or a hardware
failure, the utility displays an error message and exits.
Displaying SM BIOS Area
The SM BIOS area is displayed in ASCII format when the field is ASCII or as a number when the
field is a number. Each SM BIOS area displayed is headed with the SM BIOS area designated
name. Each field has a field name header followed by the field in ASCII or as a number.
Displaying FRU Area
The FRU area is displayed in ASCII format when the field is ASCII or as a number when the field
is a number. Each FRU area displayed is headed with the FRU area designated name. Each field
has a field name header followed by the field in ASCII or as a number. The Board, Chassis, and
Product FRU areas end with an END OF FIELDS CODE that indicates there is no more data in this
area. The Internal Use area is displayed in hex format, 16 bytes per line.
Displaying SDR Area
The SDR nonvolatile storage area is displayed in the following hex format. A Sensor Record
Number X header separates the data; where X is the number of that sensor record in the SDR area.
The next line after the header is the sensor record data in hex format delineated by spaces. Each
line holds up to 16 bytes. The data on each line is followed by the same data in ASCII format;
nonprintable characters are substituted by a period (.).
54 xSeries 343 Hardware Maintenance Manual
Using Specified CFG File
The utility can be run with the command line parameter of -cfg filename.cfg. The filename can be
any DOS accepted, eight-character filename string. The utility loads the specified CFG file and
uses the entries in the configuration file to probe the hardware and to select the proper SDRs to load
into nonvolatile storage.
Displaying Utility Title and Version
The utility displays its title:
FRU & SDR Load Utility, Version X.XX
Where X.XX is the revision number for the utility.
Configuration File
The configuration file is in ASCII text. The utility executes commands formed by the strings
present in the configuration file. These commands cause the utility to perform various tasks needed
to ultimately load the proper SDRs into the nonvolatile storage of the BMC and possibly generic
FRU devices. Some of the commands may be interactive and require you to make a choice.
Prompting for Product Level FRU Information
Through the use of a Configuration File, the utility may prompt you for FRU information.
Filtering Sensor Data Record From the SDR File
The MASTER.SDR file has all the possible SDRs for the system. These records may need to be
filtered based on the current product configuration. The configuration file directs the filtering of
the SDRs.
Updating the SDR Nonvolatile Storage Area
After the utility validates the header area of the supplied SDR file, it updates the SDR repository
area. Before programming, the utility clears the SDR repository area. The SDR file is loaded via
the .cfg File. Then the utility filters all tagged SDRs depending on the product configuration set in
the Configuration File. Non-tagged SDRs are automatically programmed. The utility also copies
all written SDRs to the SDR.TMP file. It contains an image of what was loaded, and the TMP file
is also useful for debugging the server.
Updating FRU Nonvolatile Storage Area
After the configuration is determined, the utility updates the FRU nonvolatile storage area. First it
verifies the Common Header area and checksum from the specified FRU file. The Internal Use
Area is read out of the specified .FRU file and is programmed into the nonvolatile storage. The
Chassis, Board, Product and MultiRecord areas are read out of the specified .FRU file, if they exist,
then those areas are programmed into the FRU nonvolatile storage. All the areas are also written to
the FRU.TMP file, which is useful for debugging the server.
Updating SMB FRU Nonvolatile Storage Area
After programming the BMC FRU area, the corresponding SMB fields are automatically updated
when the server is re-booted.
Configuration Software and Utilities 55
Cleaning Up and Exiting
If an update was successfully performed, the utility displays an appropriate message and then exits
with a DOS exit code of zero.
If the utility fails, it immediatelyexits with an error message and a non-zero DOS exit code.

Upgrading the Hardware 67
Handling Static-sensitive Devices
Attention: Static electricity can damage electronic devices and your system. To avoid damage,
keep static-sensitive devices in their static-protective package until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
• Do not leave the device where others can handle and possibly damage the device.
• While the device is still in its anti-static package, touch it to an unpainted metal part of the
system unit for at least two seconds. (This drains static electricity from the package and from
your body.)
• Remove the device from its package and install it directly into your system unit 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 your system unit cover or on a metal table.
• Take additional care when handling devices during cold weather because heating reduces
indoor humidity and increases static electricity.
Removing and Installing the Top Cover
Note
For proper cooling and airflow, do not operate the server with the cover
removed. Always reinstall the cover before turning the server on.
The server comes with a removable Top Cover. Removal of this cover is necessary when installing
or removing many components. You do not have to remove the Top Cover when removing or
installing power supplies or hard drives.
Statement 15
CAUTION
Make sure that the rack is secured properly to avoid tipping when the server unit is
extended.
Note
Only use a screwdriver tip to push in the lock tabs on the rack slides. A
pinch hazard exists if fingers are used for this purpose.

Removing and Installing Processors
Note
If the server has been running, any installed processor and heat sink on the
processor board(s) will be hot. To avoid the possibility of a burn, allow the
unit to cool-down and be careful when removing or installing server board
components that are located near processors.
Processor must be appropriate: You may damage the server if you install
a processor that is inappropriate for your server. Make sure your server can
handle a newer, faster processor (thermal and power considerations). For
exact information about processor interchangeability, contact your customer
service representative.
Handling Static-sensitive Devices
Attention: Static electricity can damage electronic devices and your system. To avoid damage,
keep static-sensitive devices in their static-protective package until you are ready to install them.
To reduce the possibility of electrostatic discharge, observe the following precautions:
• Limit your movement. Movement can cause static electricity to build up around you.
• Handle the device carefully, holding it by its edges or its frame.
• Do not touch solder joints, pins, or exposed printed circuitry.
