Arranging Your Workspace

Arranging Your Workspace

To get the most from your server, arrange both the equipment you
use and your work area to suit your needs and the kind of work
you do. Your comfort is of foremost importance, but light sources,
air circulation, and the location of electrical outlets also can affect
the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are
a few guidelines to help you find a position that suits you best.

Sitting in the same position for a long time can cause fatigue. A
good chair can make a big difference. The backrest and seat should
adjust independently and provide good support. The seat should
have a curved front to relieve pressure on the thighs. Adjust the
seat so that your thighs are parallel to the floor and your feet are
either flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor
and your wrists in a neutral, comfortable position. Try to keep a
light touch on the keyboard and your hands and fingers relaxed.
You can change the angle of the keyboard for maximum comfort by
adjusting the position of the keyboard feet.

Viewing Distance

Lower
Back
Support

Height

Adjust the monitor so the top of the screen is at, or slightly below,
eye level. Place the monitor at a comfortable viewing distance,

Arranging Your Workspace

usually 51 to 61 cm (20 to 24 in.), and position it so you can view it
without having to twist your body. Also position other equipment
you use regularly, such as the telephone or a mouse, within easy
reach.

Glare and Lighting

Position the monitor to minimize glare and reflections from
overhead lights, windows, and other light sources. Even reflected
light from shiny surfaces can cause annoying reflections on your
monitor screen. Place the monitor at right angles to windows and
other light sources, when possible. Reduce overhead lighting, if
necessary, by turning off lights or using lower wattage bulbs. If you
install the monitor near a window, use curtains or blinds to block
the sunlight. You might have to adjust the Brightness and Contrast
controls on the monitor as the room lighting changes throughout the
day.

Where it is impossible to avoid reflections or to adjust the lighting,
an antiglare filter placed over the screen might be helpful.
However, these filters might affect the clarity of the image on the
screen; try them only after you have exhausted other methods of
reducing glare.

Dust buildup compounds problems associated with glare.
Remember to clean your monitor screen periodically using a soft
cloth moistened with a nonabrasive liquid glass cleaner.

Air Circulation

Your server and monitor produce heat. Your server has one or
more fans that pull in fresh air and force out hot air. The monitor
lets hot air escape through vents. Blocking the air vents can cause
overheating, which might result in a malfunction or damage. Place
the server and monitor so that nothing blocks the air vents.

Attention:

To allow for air circulation, be sure to maintain the following
minimum clearances around the server:

 102 mm (4 in.) in the front
 127 mm (5 in.) in the rear

Chapter 2. Getting Started 17

Arranging Your Workspace

 51 mm (2 in.) on the left and right sides

Also, make sure the vented air is not blowing on someone else.

Electrical Outlets and Cable Lengths

The location of electrical outlets and the length of power cords and
cables that connect to the monitor, printer, and other devices might
determine the final placement of your server.

When arranging your workspace:

 Avoid the use of extension cords. When possible, plug the

server power cord directly into an electrical outlet.

 Keep power cords and cables neatly routed away from

walkways and other areas where they might get kicked
accidentally.

For more information about power cords, see “Power Cords” on
page 233.

18 Netfinity 3500 User's Handbook

Using the Stabilizing Feet

The four feet attached to the bottom cover rotate 90 degrees to
provide additional stability for your server.

Before you place the server in an upright position, rotate the four
feet a quarter turn away from the server. Then, carefully position
the server on its feet.

When you need to access the inside of the server to install options,
you might find it easier to place the server on its side, so that the
system board is facing you. If you do so, rotate the feet in towards
the server, so that they do not break off due to the weight of the
server.

Chapter 2. Getting Started 19

Using the CD-ROM Drive

Using the CD-ROM Drive

An IDE CD-ROM drive is a standard feature on all Netfinity 3500
servers. CD-ROM drives can play back or read from a CD, but
cannot write information to it. CD-ROM drives use
industry-standard, 12 cm (4.75-inch) CDs.

Follow these guidelines when using a CD-ROM drive:

 Do not place the server where the following conditions exist:

– High temperature
– High humidity
– Excessive dust

– Excessive vibration or sudden shock
– An inclined surface

– Direct sunlight

 Do not insert any object other than a CD into the drive.
 Before moving the server, remove any CD from the drive.

Handling a CD

When handling a CD, follow these guidelines:

 Hold the CD by its edges. Do not touch the surface.
 To remove dust or fingerprints, wipe the CD from the center to

the outside. Wiping the CD in a circular direction might cause
loss of data.

 Do not write or stick paper on the CD.
 Do not scratch or mark the CD.
 Do not place or store the CD in direct sunlight.
 Do not use benzene, thinners, or other cleaners to clean the CD.
 Do not drop or bend the CD.

Loading and Unloading a CD

To load and unload a CD into a CD-ROM drive:

1. Press the Eject/Load button. The tray slides out of the drive.
(Do not manually force the tray open.)

2. Place the CD in the tray with the label facing up.

3. Close the tray by pressing the Eject/Load button, or by gently
pushing the tray forward. When the tray is closed, the
CD-ROM drive in-use light on the front of the drive will
activate to indicate that the drive is in use.

4. To eject the CD, press the Eject/Load button. When the tray
slides out, carefully remove the CD.

5. Close the tray by pressing the Eject/Load button, or by gently
pushing the tray forward.

Notes:

1. If the tray does not slide out of the drive when you press the
Eject/Load button, insert one end of a large paper clip into the
emergency-eject hole located above and to the left of the
CD-ROM drive in-use light.

2. In some models, you might have to remove the front bezel from
the CD-ROM drive to access the emergency-eject hole.

Configuration Overview

Configuration Overview

You play a key role in how your server allocates resources to
organize and interconnect hardware devices and software programs.
This allocation process is referred to as configuration. The steps
required to configure your server depend on the number and types
of devices and programs that you install.

Your server supports several types of adapters. Because of this
flexibility, you can choose from among thousands of adapters and
devices that comply with any of the following standards:

 Peripheral Component Interconnect (PCI)
 Industry Standard Architecture (ISA)
 Small Computer System Interface (SCSI)

You can obtain a listing of products that are compatible with your
server, and related configuration information, by accessing the
following World Wide Web address:

http://www.us.pc.ibm.com/compat/

Jumpers and switches are used to define certain configuration
values on the system board, adapters, and other devices. For details
about system-board jumper and switch settings, see Chapter 7,
“Server Records and Specifications” on page 193. If you need to set
jumpers or switches on adapters, drives, or other devices, refer to
the documentation that comes with the devices for specific
information about the appropriate jumper and switch settings.

In general, the greater the number and variety of hardware devices
and software programs that you install in your server, the more you
will have to interact with your server and your devices to correctly
configure your system.

Your server comes with the following hardware configuration utility
programs:

 Configuration/Setup Utility program

With the Configuration/Setup Utility program, you can
configure system board functions, such as serial and parallel
port assignments; change interrupt request settings, and change

24 Netfinity 3500 User's Handbook

Configuration Overview

the startup sequence for drives that you install. You can also
use this utility program to set passwords for starting the server
and accessing the Configuration/Setup Utility program.

 SCSISelect Utility

With the built-in SCSISelect Utility program, you can configure
the SCSI devices that you install in your server. You can use
SCSISelect to change default values, resolve configuration
conflicts, and perform a low-level format on a SCSI hard disk
drive.

Before installing a new device or program, read the documentation
that comes with it. Reading the instructions helps you to determine
the steps required for installation and configuration. The following
actions are typically, but not always, required to configure your
server.

1. Run the Configuration/Setup Utility program and record the
current configuration settings.

See “The Configuration/Setup Program” on page 26.

2. Set jumpers or switches on the server's system board.
See Chapter 7, “Server Records and Specifications” on page 193.

3. Set jumpers or switches on the device.
See the device installation instructions.

4. Install the device in the server.
See Chapter 4, “Installing Options” on page 51.
Reserve ISA legacy resources for ISA adapters. See “ISA Legacy

Resources” on page 40.

5. Resolve configuration conflicts.
See “Resolving Configuration Conflicts” on page 42.

6. Install software programs, including device drivers.
Refer to the information that comes with your IBM ServerGuide

package for more information.

Chapter 3. Configuring Your Server 25

The Configuration/Setup Program

The Configuration/Setup Program

For most configurations, the server will operate using the default
system settings. You need to change the settings only to resolve
configuration conflicts or to enable or change device functions.

When you want or need to change the default settings, the
Configuration/Setup Utility program provides a convenient way to
display and change the settings.

After you run and exit the Configuration/Setup Utility program,
configuration information is stored in electrically erasable
programmable read-only memory (EEPROM). While the server is
powered off, the configuration information remains available for the
next system startup.

Always run the Configuration/Setup Utility program if you receive
an error message instructing you to do so. If you installed or
removed SCSI devices, run the SCSISelect Utility program (see
“Using the SCSISelect Utility” on page 46). Review this chapter and
the information that comes with the option before making changes.
Also, record the current settings (see Chapter 7, “Server Records
and Specifications” on page 193) before making any changes.

To start the Configuration/Setup Utility program:

1. Turn on the server and watch the screen.
If your server is already turned on, turn off the server, wait a

few seconds until all in-use lights go off, and then turn the
server back on. (Do not use Ctrl+Alt+Del to restart the server.)

2. When the message Press F1 to enter Configuration/Setup
appears, press F1. The Configuration/Setup Utility program
menu appears. For information about the menus, see “Using
the Configuration/Setup Utility Program” on page 28.

26 Netfinity 3500 User's Handbook

The Configuration/Setup Program

Notes:

1. If an administrator password is not set, the Configuration/Setup
Utility program starts once you complete the startup procedure.

2. If an administrator password is set, but a power-on password is
not set, you must enter the administrator password to access the
Configuration/Setup Utility program.

3. If you have set both an administrator and a power-on password,
you can enter either one. However, to change any settings in
the Configuration/Setup Utility program, you must enter the
administrator password. If you enter the power-on password,
you will be able to view limited information in the
Configuration/Setup Utility program, but you will not be able
to change any settings.

4. If a configuration error occurs, a prompt appears before the
operating system starts ( see “Resolving Configuration
Conflicts” on page 42).

2. Enter your password and press the Down Arrow (↓) key.
You can use any combination of up to seven characters (A–Z,

a–z, and 0–9) for this password. Keep a record of the password
in a safe place.

3. Enter your password again.

4. Define the Power-On Password Changeable by User field.
Choices are:

Yes The power-on password can be changed without entering

the administrator password, if the administrator password
is set.

No The power-on password cannot be changed unless the

administrator password is entered, if the administrator
password is set.

5. Select Change Administrator Password and follow the
instructions on the screen.

Note: If an administrator password is set and then forgotten, you

must complete one of the following to regain access to the
Configuration/Setup Utility program:

 If enhanced security is disabled (default setting), you

must remove the server cover and move a jumper on the
system board. (See “Using the Clear CMOS Request

Chapter 3. Configuring Your Server 35

Using the Configuration/Setup Utility Program

Jumper to Erase Forgotten Passwords” on page 204 for
further information.)

 If enhanced security is enabled, you must replace the

system board.

To delete an administrator password:

1. Select Administrator Password.

2. Select Delete Administrator Password and follow the

instructions on the screen.

If both a power-on and administrator password are set, you can
enter either password to complete the system startup. However, the
administrator password provides access to all menu choices, and
provides the ability to change information. If you enter the
power-on password, you will be able to view limited information in
the Configuration/Setup Utility program, but you will not be able to
change any settings.

Using the Enhanced Security Features

With enhanced security, your administrator password and
drive-startup sequence are stored in a highly protected, nonvolatile,
security EEPROM module. When your administrator password and
drive-startup sequence are stored in the security EEPROM, they
remain intact even if the battery expires or is removed.

Attention:

If enhanced security is enabled, and you forget or lose the
administrator password, you must replace the system board in your
server to regain access to the Configuration/Setup Utility program.

If enhanced security is enabled and you have set an administrator
password, your server will operate as follows:

 The security EEPROM is protected from unauthorized access

once the startup procedures are complete.
With enhanced security disabled, the contents of the EEPROM

are write protected, and the server can function in a network
environment because the POST/BIOS utility program will allow
updates to the system programs.

36 Netfinity 3500 User's Handbook

Using the Configuration/Setup Utility Program

With enhanced security enabled, the POST/BIOS utility program
will not allow updates to the system programs. In a network
environment, this might prevent certain functions from being
performed remotely.

 If the cover of your server has been removed, a

tamper-detection feature will halt system processing and deny
access to the keyboard and mouse until the administrator
password is entered. This feature will work if your server is
powered on or off.

To enable or disable enhanced security:

Note: Enhanced security can be enabled or disabled only when you

update the system programs in your server.

1. Insert a system programs update diskette in your server.
System programs updates are available on the World Wide
Web. To obtain up-to-date information about your server
model, access the home page for your server at the following
address: http://www.us.pc.ibm.com/server/

2. Turn on the server. If it is already turned on, you must turn it
off and back on again.

3. The update begins, and the system prompts you for the
administrator password, if you have set an administrator
password.

4. When you enter the administrator password, the update diskette
will continue to run, and you are given the option of enabling
or disabling enhanced security.

To set, change, or delete an administrator password protected by
enhanced security:

1. Turn off all attached devices and the server.

2. See Chapter 4, “Installing Options” on page 51 for safety
information, disconnecting all cables, and removing the server
cover.

3. Locate the switch marked as 7 on the rocker switches section of
the system board. See “Setting the Administrator Password
Switch” on page 215 for the location of the switch. Move the

Chapter 3. Configuring Your Server 37

Using the Configuration/Setup Utility Program

switch to the ON position. (It might be helpful to use the end
of a small screwdriver to set the switch.)

Note: You must know the administrator password to change or

delete it.

4. Move the switch back to the OFF position after you have set,

changed, or deleted your password.

5. Replace the cover. Then, turn on the server.

Restricting Access to IDE Devices and Diskette Drives

The setting for the Secure IDE and Diskette Drives option controls
who has access to the IDE devices and diskette drives (user and
administrator, or administrator only). Your server comes with this
feature set to Enable, so that both the user and administrator have
access to the IDE devices and diskette drives.

To disable access to the IDE devices and diskette drives:

1. Select Secure IDE Devices and Diskette Drives from the
System Security menu; then, press Enter.

2. Select a device; then, press the Left Arrow (←) or Right Arrow
(→) key to toggle the entry to Disable.

Updating POST/BIOS Update over the Network

Using this option, the BIOS can be updated remotely from a
network server. If an administrator password is set, it does not have
to be entered from the server to access this function. Consult your
network administrator for information on setting up your network
server to perform POST and BIOS updates.

To access the POST/BIOS Update setting:

1. Select POST/BIOS Update.

2. Select Update POST/BIOS from network.

3. To enable update POST/BIOS over the network, select Enabled.
To disable, select Disabled.

ISA Legacy Resources

Plug and Play is a configuration method that makes expanding your
server easier. Support for Plug and Play is built into the system
board of your server.

If an adapter is Plug and Play, there are no switches or jumpers that
must be set on the adapter. A Plug and Play adapter comes with
configuration specifications set in memory to provide installation
information to the server during startup. When you install or
remove Plug and Play adapters, this information is interpreted by
the BIOS, which supports Plug and Play technology. If the required
resources are available, the BIOS software automatically configures
the adapter around the resources already in use by other devices.

Most adapters designed for PCI slots are Plug and Play devices that
are auto-configuring. However, many ISA adapters are not Plug
and Play devices. These adapters are known as legacy adapters. If
you install a legacy adapter, you must manually configure it by
setting switches or jumpers on the adapter, and by allocating or
reserving the system resources that the adapter will use.

Note: See “Resolving Configuration Conflicts” on page 42 for

information about handling resource conflicts.

Select ISA Legacy Resources to identify the available system
resources:

 Memory
 I/O ports
 DMA
 Interrupt

40 Netfinity 3500 User's Handbook

Using the Configuration/Setup Utility Program

Note: The menus do not contain resources that are used by the

system or by previously installed Plug and Play adapters.

To store the legacy resource information for an installed adapter:

1. Select ISA Legacy Resources; then, use the Up Arrow (↑) or

Down Arrow (↓) key to highlight the system resource that you
want to change.

2. Select a resource; then, use the Left Arrow (←) or Right Arrow
(→) key to select a configuration choice.

If you remove an ISA legacy adapter, you must redefine the system
resource as Available.

Power Management

With Power Management, the server and monitor can be set to use a
reduced-power state if they are inactive for a specified length of
time. You can also specify options to automatically start the server.

Attention:

The ACPI BIOS Mode feature is the only available Power
Management feature.

The APM BIOS Mode feature is set to Disabled. Do not change
this default value.

Using the Automatic Configuration and Power Interface BIOS Mode

When the automatic configuration and power interface (ACPI) BIOS
mode is enabled, the operating system controls the power
management features of your server and the settings for APM BIOS
mode are ignored. Refer to your operating-system documentation
to determine if ACPI is supported.

To set ACPI BIOS mode:

1. Select Power Management from the Configuration/Setup Utility
program menu.

2. Set ACPI BIOS Mode to Enabled or Disabled as desired using
the Left Arrow (←) or Right Arrow (→) key.

Chapter 3. Configuring Your Server 41

Resolving Configuration Conflicts

Resolving Configuration Conflicts

The resources used by your server consist of IRQs, DMA, I/O port
addresses, and memory. This information is useful when a resource
configuration conflict occurs.

Conflicts in the configuration occur if:

 A device that you installed requires the same resource as

another device. (For example, a conflict occurs when two
adapters try to write to the same address space.)

 A device resource is changed (for example, changing jumper

settings).

 A device function is changed (for example, assigning COM1 to

two serial ports).

 A software program is installed that requires the same resource

as a hardware device.

The steps required to resolve a configuration error are determined
by the number and variety of hardware devices and software
programs that you install. If a hardware configuration error is
detected, a configuration error message appears after the server
completes POST and before the operating system is loaded. You
can bypass the error by pressing Esc while the error message is
displayed.

The Configuration/Setup Utility program configures only the
system hardware and interrupt requests. The program does not
consider the requirements of the operating system or the application
programs. For these reasons, memory-address configuration
conflicts might occur. You can resolve some memory-address
conflicts by changing the address of the conflicting hardware option,
or by changing or moving the hardware. You might have to resolve
other memory-address conflicts by changing some software
parameters. See “Resolving Hardware Configuration Conflicts” on
page 43 and “Resolving Software Configuration Conflicts” on
page 43, respectively, for additional information. See Chapter 5,
“Solving Problems” on page 117 for information about
troubleshooting hardware and software problems.

42 Netfinity 3500 User's Handbook

Resolving Configuration Conflicts

Resolving Hardware Configuration Conflicts

Use the following information to help resolve hardware
configuration conflicts:

1. Run the Configuration/Setup Utility program to view and
change the resources that the system board functions use.
Record the current settings before making any changes. (See
“The Configuration/Setup Program” on page 26 for
instructions.)

2. Determine which adapter or device is causing the conflict.

3. Change adapter jumpers or switches. Some devices use jumpers
and switches to define the system resources that they need. If
the settings are incorrect or set to use a resource that cannot be
shared, a conflict occurs, and the device will remain deactivated
by the configuration program.

4. Change system board jumpers or switches. See “Preparing to
Add Options” on page 56 for instructions for removing the
cover. Then, refer to the system-board diagram inside your
server.

5. Remove the device or adapter. Some configurations are not
supported. If you must remove an adapter, see “Installing or
Removing Adapters” on page 61.

Resolving Software Configuration Conflicts

The Configuration/Setup utility might change the memory-address
space used by some hardware options. If this happens, the new
memory-address space and IRQs used by some hardware options
might conflict with addresses defined for use through application
programs.

If a conflict exists, one or more of the following conditions might
exist:

 The system cannot load the operating system.
 The system does not work.
 An application program does not operate, or it returns an error.
 Screen messages indicate that a memory-address conflict exists.

Chapter 3. Configuring Your Server 43

Configuring the Ethernet Controller

Note: Start the Configuration/Setup Utility program to view the

addresses that are used by your system board functions.

The best way to resolve memory-address conflicts is to change the
addresses that are used by the application program or the device
driver. You can use the Configuration/Setup Utility program to
view and change addresses.

Configuring the Ethernet Controller

Your Netfinity 3500 server comes with an Ethernet controller on the
system board. The Ethernet controller provides 10BASE-T and
100BASE-TX support through the RJ-45 connector on the back of
your server. When you connect your server to the network, the
Ethernet controller automatically detects the data-transfer rate (10
Mbps or 100 Mbps) on the network and then sets the controller to
operate at the appropriate rate. 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), half duplex
(HDX), or full duplex (FDX). This process is also known as
auto-negotiation. This auto-negotiation occurs without requiring
software intervention. The controller supports half-duplex (HDX)
and full-duplex (FDX) modes at both speeds.

However, auto-negotiation works only if the hub or switch at the
other end of the network also supports auto-negotiation. If the hub
or switch does not support auto-negotiation, the speed (10 Mbps or
100 Mbps) will still be detected correctly, but half-duplex mode will
always be selected. A full-duplex switch that does not support
auto-negotiation will not attach to the Netfinity 3500 server in
full-duplex mode. In this case, if you want the network to operate
in full-duplex mode, you must manually override the settings to
obtain a full-duplex connection. Refer to your Ethernet
documentation for additional information.

Attention:

 The 10BASE-T Ethernet and the 100BASE-TX Fast Ethernet

cabling in the network must be Category 5 or higher to meet
various standards, including electromagnetic compatibility.

44 Netfinity 3500 User's Handbook

Configuring the Ethernet Controller

 You must install a device driver to enable your operating

system to address the Ethernet controller. Use ServerGuide to
install this device driver. Refer to your ServerGuide package for
instructions on installing device drivers. For more information
about ServerGuide, see “What Your IBM Netfinity 3500 Server
Offers” on page 4.

Fast Ethernet operates at a data rate of 100 Mbps; that is, ten times
faster than standard Ethernet. However, except for the different
operating speeds, Fast Ethernet and standard Ethernet are
structurally identical. Applications and protocols that are currently
installed on a standard Ethernet system can be seamlessly migrated
to a Fast Ethernet system. (In a very small number of cases, minor
tuning might be required to adjust the application to the faster
response time of a Fast Ethernet system.) Because of the
equivalence of the two types of Ethernet, mixed Ethernet and Fast
Ethernet systems also can be designed and implemented.

The bandwidth required at each workstation connected to a server is
generally far less than the bandwidth required at the server. This is
because the server might have to handle the bandwidth of multiple
workstations at the same time. A cost-effective solution to the
bandwidth requirements of this type of system is a mixed Ethernet
and Fast Ethernet network. This mixed network consists of
standard Ethernet connections at the workstations and Fast Ethernet
connections at the servers.

The Ethernet controller is a PCI device, and is therefore, a Plug and
Play device. You do not have to set any jumpers or configure the
controller for your operating system before you use the Ethernet
controller.

The Ethernet controller supports the auto-detection mode only.
When you install your device drivers and configure the Ethernet
controller for use with your operating system, do not select the
10BASE-T mode. To ensure proper operation of your controller,
always select the default parameters provided.

Chapter 3. Configuring Your Server 45

Using the SCSISelect Utility

Notes:

1. For troubleshooting information, see “Troubleshooting the
10/100 Mbps Ethernet Controller” on page 173.

If you need additional Ethernet connections, you can install an
Ethernet adapter, such as an IBM 10/100 Ethernet adapter. Review
your network-adapter documentation for any additional
configuration requirements.

Note: If you are installing an IBM 10/100 Ethernet adapter, be sure

to run the Ethernet diagnostics and record the server's
Ethernet configuration information before you install the
adapter.

54 Netfinity 3500 User's Handbook

Handling Static-Sensitive Devices

Handling Static-Sensitive Devices

Static electricity, though harmless to you, can seriously damage
server components or options.

Note: When you are adding an internal option, do not open the

static-protective package containing the option until you are
instructed to do so.

When you handle options and other server components, take these
precautions to avoid damage from static electricity:

 Limit your movement. Movement can cause static electricity to

build up around you.

 Always handle components carefully. Handle adapters, the

processor board, and memory modules by the edges. Never
touch any exposed circuitry.

 Prevent others from touching components.
 When you are installing a new option, touch the static-protective

package containing the option to a metal expansion-slot screw
or other unpainted metal surface on the server for at least two
seconds. (This reduces static electricity from the package and
from your body.)

 When possible, remove the option and install it directly into the

server without setting the option down. When this is not
possible, place the static-protective package that the option
comes in on a smooth, level surface and place the option on it.

 Do not place the option on the server's covers or any metal

surface.

Chapter 4. Installing Options 55

Preparing to Add Options

Preparing to Add Options

Before you begin:

 Be sure that your current server configuration is working

properly.

 If you have not already done so, locate the keys to the cover

lock. At the time of shipment, two keys are attached to the
back of the server, over the keylock. Store the keys in a safe
place.

 Obtain a small, flat-blade screwdriver.
 Read “Electrical Safety” on page 54 and “Handling

Static-Sensitive Devices” on page 55.

 Read “Using the Stabilizing Feet” on page 19.

CAUTION:
To avoid possible injury while moving or lifting the server, ask
another person to help you.

Disconnecting Cables and Removing the Cover

1. Remove any media (diskettes or CDs) from the drives; then,
turn off all attached devices and the server.

2. Touch the rear of the bare metal frame to dissipate any static
electricity from your body.

3. Before disconnecting cables, be sure to note where they attach,
so that you can correctly reattach them later.

Note: If you are in the United Kingdom, you must perform

step 5 before step 4.

4. Unplug all power cords (cables) from electrical outlets.

5. If you have a modem or fax machine attached to the server,
disconnect the telephone line from the wall outlet and the
server.

Accessing the System Board

Before you can install or remove certain options, you might need to
access the system board. For example, you might need to remove
adapters, drives, and cables that impede your access to components
on the system board. You also need to access the system board
before you can install or remove such options as adapters, memory
modules, and microprocessors, because these devices reside on the
system board.

To access the system board more easily, place the server on its side,
so that the system board is facing you, on a flat, sturdy surface,
such as a table.

Note: To see a list of the system-board components and an

illustration that shows their locations, see “System Board
Illustration” on page 203.

Working with Adapters

Working with Adapters

Adding an adapter, such as a communication adapter, extends the
capabilities and power of your server. For example, you can add a
redundant array of independent disks (RAID) adapter that can
enhance logical-drive capacity and performance.

Note: For a complete list of the adapters that your server supports,

go to http://www.us.pc.ibm.com/compat/ on the World
Wide Web, or contact your IBM marketing representative.

When you are installing or removing adapters, it is important to
resolve any resource conflicts that might arise. For example, if you
install an ISA legacy adapter, you might need to manually configure
the adapter by setting a variety of switches on the adapter and by
using the Configuration/Setup Utility program.

Many adapters now use Plug and Play technology, which enables the
server to automatically configure the adapter, provided that the
required resources are available. Refer to the instructions that come
with your adapter to determine if it is Plug and Play. For more
information, see “ISA Legacy Resources” on page 40.

Adapter Considerations

Your server supports ISA and PCI adapters. You can install up to
six adapters in the connectors on the system board. These
connectors are known as expansion slot connectors.. The expansion
slots are located on the rear of the server (see “Input/Output
Connectors” on page 10 for an illustration).

Your server system board contains two 16-bit, ISA-bus expansion
slot connectors and four 32-bit, PCI-bus expansion slot connectors.
One expansion slot connector is a shared PCI/ISA slot connector.
One slot connector supports only ISA adapters; the remaining slot
connectors support only PCI adapters. Your server supports only

5.0-volt adapters on the PCI bus.

Chapter 4. Installing Options 59

Working with Adapters

Notes:

1. Slot 1 is an Accelerated Graphics Port (AGP). You can install
only a special AGP graphics adapter in this slot. Your server
comes with an AGP graphics adapter installed in this slot.

2. You can install only a half-length PCI adapter in expansion
slot 2. You can install half-length and full-length adapters in
expansion slots 3 through 6.

3. If you have high-performance PCI adapters, such as RAID
adapters, install them in expansion slots 3, 4, or 5. Do not use
slot 2 for high-performance PCI adapters.

4. If a component in the server or on the adapter interferes with
the installation, use another slot.

The following figure shows the location of the expansion slot
connectors on the system board.

Slot 1 (AGP)
Slot 2 (PCI)

Slot 3 (PCI)
Slot 4 (PCI)

60 Netfinity 3500 User's Handbook

Working with Adapters

Note: Expansion slot 5 is a shared slot. Shared slots can be

occupied by an adapter attached to either the PCI slot
connector or the adjacent ISA slot connector, but not both.

Attention:
To avoid possible damage to adapters and server components, be
sure that the adapters that you install do not touch each other or the
other components (such as the microprocessor) inside the server.

Installing or Removing Adapters

This section gives the procedure for installing an adapter. If you
want to remove an adapter, reverse the order of the following steps.

Notes:

1. See “Input/Output Connectors” on page 10 for an illustration of

Otherwise, go to “Completing the Installation” on page 113.

Working with Memory Modules

Adding system memory to your server can make programs run
faster. You can increase the amount of system memory by installing
options called memory modules.

The maximum amount of system memory your server supports is
512 MB. You can add memory to your server to increase system
performance. Your server has four connectors for installing
system-memory modules. These connectors are referred to as banks
0 through 3.

Memory Connectors

Chapter 4. Installing Options 63

Working with Memory Modules

The memory modules that your server uses are dual-inline memory
modules (DIMMs). The DIMMs that come with your server are

synchronous dynamic random-access memory (SDRAM) with error
correcting code (ECC). These memory modules have a speed of 66
MHz. You can add extra memory modules or replace existing
memory modules.

Notes:

1. Your server comes with one or more dual-inline memory
modules (DIMMs) installed.

2. Install DIMMs with a maximum height of 6.35 cm (2.5 inches).

3. Use only 3.3 V unbuffered DIMMs.

4. The server supports 32 MB, 64 MB, and 128 MB DIMMs.

5. When you are installing memory modules, install them in
adjacent connectors, with no vacant memory connectors in
between.

6. If you are installing DIMMs of different sizes, install the DIMMs
with greater memory capacity starting with the connector closest
to the edge of the system board (Bank 0).

7. After installing or removing a DIMM, you must save the new
configuration information using the Configuration/Setup Utility
program. See “Using the Configuration/Setup Utility Program”
on page 28.

Expansion Bays

Installing or Removing Internal Drives

Drives are devices that your server uses to store and retrieve data.
You can add drives to your server to increase storage capacity and
to enable your server to read multiple types of media. Several types
of drives are available, such as:

 Diskette
 Hard disk

 Rewritable optical disc

 Tape

Expansion Bays

Internal drives are installed in bays. The bays are referred to as
bay 1, bay 2, and so on.

Your server comes with one 3.5-inch, 1.44 MB diskette drive, one

5.25-inch CD-ROM drive, and, in some models, a 3.5-inch hard disk
drive. The following illustration shows the server front view, with
the side panel removed.

Open Bays: Your server's design accommodates 3.5-inch and

5.25-inch devices, such as hard disk, tape, and rewritable optical
disk drives. The number and capacities of the hard disk drives
vary by model.

For information on the supported types of drives and their
installation, see “Drive Specifications” on page 71 and
“Preinstallation Steps (All Bays)” on page 76.

Diskette Drive: The 3.5-inch, 1.44 MB3 diskette drive uses
1 MB (unformatted) or 2 MB (unformatted) diskettes.

Your server comes with an IDE CD-ROM drive installed in bay 1
and a 3.5-inch diskette drive installed in bay 4. Some models come
with a preinstalled 3.5-inch hard disk drive in bay 6; open-bay
models come with bay 6 empty.

5

Removable media include CD-ROMs, optical discs, diskettes, and tapes. However, the server only supports one diskette
drive (standard in bay 4).

6

In some models, the CD-ROM drive might be set as the default startup (or boot) drive. However, if a hard disk drive is
preinstalled, you can change the startup sequence, and specify the hard disk drive as the startup drive. See “Start Options”
on page 31 for information about changing the startup sequence.

7

Drives that are higher than 41.3 mm (1.6 in.) cannot be installed.

8

One slim-high drive has a height of 25.4. mm (1.0 in.). One half-high drive has a height of 41.3 mm (1.6 in.). Therefore, you
can install two slim-high drives or one half-high drive between bays 5 and 6.

Types of Cables

Your server uses cables to connect IDE and SCSI drives to the
power supply and system board. Each cable connector is designed
to fit a corresponding drive connector. The following cables are
provided:

 Four-wire power cables connect most drives to the power supply.

At the end of these cables are plastic connectors that attach to
different drives; these connectors vary in size. Also, certain
power cables attach to the system board.

 Flat signal cables for connecting IDE and diskette drives to the

system board. Signal cables are sometimes called ribbon cables.
The following ribbon signal cables come with your server to
connect IDE and diskette drives:

– The IDE signal cable has three connectors. One of these

connectors is attached to the CD-ROM drive, one is a spare,
and the third attaches to the primary IDE connector on the
system board.

– One signal cable has one connector for attaching the diskette

drive to the diskette-drive connector on the system board.

 A flat SCSI signal cable for connecting devices to the SCSI

adapter.

Since your server is equipped with an UltraSCSI controller, it has a
ribbon cable that is connected to the internal SCSI hard disk drive.
One end of this cable is connected to the 68-pin, Channel A SCSI
connector on the system board. This cable provides four connectors
for attaching other internal SCSI devices.

For more information about SCSI devices, see “SCSI Drives” on
page 74.

Note: To locate connectors on the system board, see “System Board

Illustration” on page 203.

72 Netfinity 3500 User's Handbook

The following are some important points to remember when
connecting power and signal cables to internal drives:

 The diskette drive, hard disk drive, and CD-ROM drive that are

preinstalled in your server come with power and signal cables
attached. If you replace any drives, it is important to remember
which cable is attached to which drive.

 When you install a drive, ensure that the connector at the end of

the signal cable is connected to the system board.

 If two IDE devices are used on a single cable, one must be

designated as the primary or master device and the other a
secondary or subordinate device; otherwise, some of the IDE
devices might not be recognized by the system. The primary or
secondary designation is determined by switch or jumper
settings on each IDE device.

In this server, the CD-ROM drive is the primary device. If you
install a second IDE device, it must be the secondary device.

 To attach an external SCSI drive, you must install an

appropriate adapter in the server.

For help in selecting drives, cables, and other options for your
server, do one of the following:

 Within the United States, call 1-800-IBM-2YOU (1-800-426-2968),

your IBM reseller, or your IBM marketing representative.

 Within Canada, call 1-800-565-3344 or 1-800-465-7999.
 Outside the United States and Canada, contact your IBM reseller

or IBM marketing representative.

Chapter 4. Installing Options 73

SCSI Drives

Some drives have a special design called small computer system
interface (SCSI). This design allows you to attach multiple drives to
a single connector.

Note: Any information about SCSI drives also applies to other SCSI

devices, such as scanners and printers.

Your Netfinity 3500 server supports drives that comply with
American National Standards Institute (ANSI) SCSI Standards
X3.131-1986 (SCSI), X3.131-1994, (SCSI-2), X3.277-1996 (SCSI-3
Fast-20 parallel interface), and X3.253-1995 (SCSI-3 parallel interface).

For a complete list of the SCSI devices that your server supports, go
to http://www.us.pc.ibm.com/server/ on the World Wide Web.

SCSI Physical Unit Numbers

When more than one physical device is connected to the same
UltraSCSI controller, the devices compete for support from the
UltraSCSI controller. Because the UltraSCSI controller
communicates with only one device at a time, the priority of a
device is based on its SCSI identification (ID). The highest priority
IDs are 7 to 0; the lowest priority IDs are 15 to 8.

If you install additional SCSI devices, you must set a unique ID for
each SCSI device that you connect to the integrated SCSI-2
connector. This unique ID enables the UltraSCSI controller to
identify the devices and to prevent two devices from sending or
receiving data on the SCSI bus at the same time. SCSI devices use a
variety of methods to set the SCSI ID, such as jumpers,
thumbwheels, or switches.

The SCSI device ID is also known as the SCSI address or physical unit
number (PUN).

The UltraSCSI controller in your server supports SCSI IDs 0 to 15;
ID 7 is reserved for the controller. The default startup (boot) SCSI
ID is 0 for an internal SCSI hard disk drive in Channel A. Use
SCSISelect to view the SCSI IDs of SCSI devices in your server. (See
“Using the SCSISelect Utility” on page 46 for more information.)

74 Netfinity 3500 User's Handbook

If you install wide (16-bit) SCSI devices, you can set the IDs to any
whole number between 0 and 6, or between 8 and 15. If you install
narrow (8-bit) SCSI devices, you can set the IDs to any whole
number between 0 and 6.

SCSI Logical Unit Number

Each physical device has a physical unit number (PUN) and a
logical unit number (LUN). If a physical device supports no logical
devices, its LUN is 0. Most SCSI devices support only LUN 0.
Certain types of physical SCSI devices (bridge controllers) can support
more than one logical device.

For example, a printer controller might support up to eight printers.
The printer controller is a physical device, and each printer is a
logical device. If the printer controller is assigned to ID 2, the ID of
the first printer appears in the SCSI device configuration as PUN 2,
LUN 0. The IDs of the other printers are PUN 2, LUN 1; PUN 2,
LUN 2; on up to PUN 2, LUN 7.

Termination Requirements

All Netfinity 3500 servers come with an UltraSCSI controller on the
system board. This UltraSCSI controller provides termination for
one end of the SCSI bus (cable) in your server. However, the SCSI
bus must be terminated at both ends only. Any SCSI devices that
are installed must have their termination set to Disabled.

 When you install devices in bays 2, 3, 5, and 6, you must disable

the termination for the devices before you install them.

 If you connected external SCSI devices to your server, set the

termination for the last device on the external cable to Enabled.
See the device documentation for instructions.

Refer to the instructions that come with the SCSI device for more
information about termination.
