Chapter 1. Introducing the IBM xSeries 240 3

What your server offers

The unique design of your IBM xSeries 240 takes advantage of advancements in symmetric multiprocessing (SMP), data storage, and memory management. Your server combines:

 Impressive performance using an innovative approach to SMP

Your server supports up to two Pentium III microprocessors. Your server comes with one microprocessor installed; you can install an additional microprocessor to enhance performance and provide SMP capability.

 Large data-storage and hot-swap capabilities

All models of the server support up to six hot-swap hard disk drives. This hot-swap feature enables you to remove and replace hard disk drives without turning off the server.

 Hot-plug PCI adapter capabilities

Your server has three hot-plug slots for PCI adapters. This feature is sometimes referred to as Active PCI. With operating system support, you can replace failing hot-plug PCI adapters without turning off the server. If the hot-add feature is supported by your operating system and the PCI adapter, you can also add PCI adapters in these slots without turning off the server.

 Redundant cooling and power capabilities

The redundant cooling and hot-swap capabilities of the fans in your server allow continued operation if one of the fans fails. You can also replace a failing fan without turning off the server.

The two 250-watt power supplies in your server provide redundant power for many configurations of your server. If the average load on your server is less than 250 watts and a problem occurs with one of the power supplies, the other power supply can handle the load. For power loads above 250 watts, you can install a third, optional power supply to provide a full 500 watts of power. The NON REDUNDANT light emitting diode (LED) on the diagnostic LED panel is lit when the power load is 250 watts or greater with two power supplies installed.

 Large system memory

The memory bus in your server supports up to 4GB of system memory. The memory controller provides error correcting code (ECC) support for up to four industry-standard PC133, 3.3 V, 168-pin, 8-byte, registered, synchronous-dynamic-random access memory (SDRAM) DIMMs (Intel PC-Registered SDIMM Specifications, Revision 1.0 or later), synchronous, dual inline memory modules.

4 IBM xSeries User's Reference

 System-management capabilities

Your server comes with an Advanced System Management Processor on the system board. This processor, in conjunction with the systems-management software provided with your server, allows you to manage the functions of the server locally and remotely. The Advanced System Management Processor also provides system monitoring, event recording, and dial-out alert capability.

Note: The Advanced System Management Processor is sometimes referred to

as the service processor.

Refer to the information provided with the systems-management software for more information.

 Integrated network environment support

Your server comes with an Ethernet controller on the system board. This Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps networks. The server automatically selects between 10BASE-T and 100BASE-TX. The controller provides full-duplex (FDX) capability, which allows simultaneous transmission and reception of data on the Ethernet local area network (LAN).

 Redundant network-interface card

The addition of an optional, redundant network interface card (NIC) provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associated with this primary connection is automatically switched to the redundant NIC. This switching occurs without data loss and without user intervention.

 IBM ServerGuide CDs

The ServerGuide



CDs included with your server provide programs to help you set up your server and install the network operating system (NOS). The ServerGuide program detects the hardware options installed and provides the correct configuration program and device drivers. For more information, see the ServerGuide topic provided on the IBM xSeries Documentation CD.

Your server is designed to be cost-effective, powerful, and flexible. It uses peripheral component interconnect (PCI) bus architecture to provide compatibility with a wide range of existing hardware devices and software applications.

As always, your IBM server meets stringent worldwide certifications for power, electromagnetic compatibility (EMC), and safety.

Chapter 1. Introducing the IBM xSeries 240 5

Reliability, availability, and serviceability features

Three of the most important features in server design are reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on your server; that your server is available when you want to use it; and that should a failure occur, you can easily diagnose and repair the failure with minimal inconvenience.

The following is an abbreviated list of the RAS features that your server supports.

Chapter 2. 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

Seat 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, 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.

 Copyright IBM Corp. 2000 17

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; usually, 15 cm (6 inches)of air space is sufficient. 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 cords

directly into electrical outlets.

 Keep power cords and cables neatly routed away from walkways and other

areas where they might get kicked accidentally.

Chapter 3. Configuring your server

This chapter provides information about the Configuration/Setup Utility program. This program is part of the basic input/output system (BIOS) that comes with your server. Using these programs, you can set the system date and time, define input and output device parameters, and define system security.

The ROM-based diagnostic program that comes with the server provides diagnostic support for the system memory, disk drives, and other system components.

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 PCI adapters and SCSI devices. Because of this flexibility, you can choose from among many adapters and devices.

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 programs:

 Configuration/Setup Utility program

With the built-in Configuration/Setup Utility program, you can change serial and parallel port assignments, interrupt request (IRQ) settings, and the startup sequence for drives that you install. You also can use this program to set passwords for starting up the server and accessing the Configuration/Setup Utility program.

 SCSISelect Utility program

With the built-in SCSISelect Utility program, you can configure the SCSI devices that you attach to the SCSI controller. 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.

 Copyright IBM Corp. 2000 19

The Configuration/Setup Utility 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 (for example, defining diskette types, and so on).

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

Always run the Configuration/Setup Utility program if you add, remove, or relocate any hardware option, or if you receive an error message instructing you to do so. Review this chapter and the information that comes with the option before making changes.

To start the Configuration/Setup Utility program:

1. Turn on the server and watch the screen.

2. When the message Press F1 for Configuration/Setup appears, press F1. Note: If you enter the power-on password and an administrator

(supervisor-level) password is also set, a limited version of the menu appears. To see the full menu, you must restart the server and enter the administrator password when you are prompted to enter a password. See “System Security” on page 23 for additional information.

The Configuration/Setup Utility main menu appears. For information about the menu, see “Using the Configuration/Setup Utility main menu” on page 21.

Notes:

a. When the message Press F2 for Diagnostics appears, press F2 to run

the diagnostic programs. For information about running the diagnostic programs, see “Diagnostic programs” on page 110.

b. When the message Press Alt-F1 for System Partition Boot appears,

press Alt+F1 to start the system from the system partition. See the ServerGuide topic for information about using ServerGuide to create a system partition.

Exit Setup

If you have made any changes, you will be asked if you want to save the changes or exit without saving the changes.

Configuring options

Before installing a new device or program, read the documentation that comes with it. Reading the instructions helps you to determine the steps that are required for installation and configuration. The following list provides a preview of the actions that might be required to configure your server.

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

See “The Configuration/Setup Utility program” on page 20.

2. Set jumpers or switches on the server components. See “Changing jumper positions” on page 103.

3. Set jumpers or switches on the device. See the instructions that come with the adapter.

4. Install the adapter in the server. See “Working with adapters” on page 53.

5. Install software programs. See the installation instructions that come with the software.

6. Resolve configuration conflicts. See “Resolving configuration conflicts.”

Resolving configuration conflicts

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

Conflicts in the configuration occur if:

 A device is installed that 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.

30 IBM xSeries User's Reference

The Configuration/Setup Utility program configures the system hardware and PCI IRQs. The program does not consider the requirements of the operating system or the application programs. See “Resolving software configuration conflicts” on page 31 for additional information.

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 resources

used by the system functions and the installed options. Record the current settings before making any changes. (See “The Configuration/Setup Utility program” on page 20 for instructions.)

2. Determine which adapter or device is causing the conflict. (See Chapter 6,

“Solving problems” for instructions.)

3. Change adapter jumpers or switches. Some devices use jumpers and switches

to define the system resources that the devices 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 jumpers or switches. See “Changing jumper positions” on

page 103.

5. Remove the device or adapter. Some configurations are not supported. If you

must remove an adapter, see “Working with adapters” on page 53.

Resolving software configuration conflicts

The memory-address space and IRQs used by some hardware options might conflict with addresses defined for use through application programs or the expanded memory specification (EMS). (EMS is used only with DOS.)

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 conflict exists.

To resolve conflicts, you can change the software or hardware configuration. Note: Start the Configuration/Setup Utility program to view the addresses used by

your server functions. (See “The Configuration/Setup Utility program” on page 20 for instructions.)

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

If a device driver is causing a memory-address conflict, refer to your operating-system documentation or the documentation that comes with the device drivers.

Chapter 3. Configuring your server 31

Using the SCSISelect utility program

Note: If your server has a RAID adapter installed, use the configuration method

supplied with the RAID adapter to view or change SCSI settings for attached devices.

Depending on the hard disk drive capacity, the Low-Level Format program could take up to two hours.

When to use the Low-Level Format program

Use the Low-Level Format program:

 When you are installing software that requires a low-level format  When you get recurring messages from the diagnostic tests directing you to run

the Low-Level Format program on the hard disk drive

 As a last resort before replacing a failing hard disk drive

Note: For information about backing up all of your files, see your operating-system

documentation.

Starting the Low-Level Format program

Note: If your server has a RAID adapter installed, refer to the RAID adapter

documentation for instructions for performing a low-level format on a hard disk drive attached to the PCI RAID adapter.

1. If the hard disk is working, make a backup copy of all the files and programs on the hard disk.

Attention: The Low-Level Format program erases all data and programs.

2. Select Format Disk; then, follow the instructions on the screen.

Note: Hard disks normally contain more tracks than their stated capacity (to

34 IBM xSeries User's Reference

allow for defective tracks). A message appears on the screen if the defect limit is reached. If this happens, have the system serviced.

3. To install an operating system after the hard disk drive is formatted, follow the

instructions in the ServerGuide topic.

Configuring the Ethernet controller

Your IBM xSeries 240 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 (10Mbps or 100Mbps) 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-negotiating. This auto-negotiation occurs without requiring software intervention. The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the

network be Category 5 or higher.

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. However, you must install a device driver to enable your operating system to address the Ethernet controller (refer to the ServerGuide topic or to your operating-system documentation).

For troubleshooting information, see “Troubleshooting the Ethernet controller” on page 148.

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

Failover for redundant Ethernet

Your IBM xSeries 240 has an integrated Ethernet controller. The IBM Netfinity 10/100 Fault Tolerant Adapter is an optional redundant network interface card (NIC adapter) that you can install in your server. If you install this NIC adapter and connect it to the same logical segment as the primary Ethernet controller, you can configure the server to support a failover function. You can configure either the integrated Ethernet controller or the NIC adapter as the primary Ethernet controller. In failover mode, if the primary Ethernet controller detects a link failure, all Ethernet traffic associated with it is switched to the redundant (secondary) controller. This switching occurs without any user intervention. When the primary link is restored to an operational state, the Ethernet traffic switches back to the primary Ethernet controller. The switch back to the primary Ethernet controller can be automatic or manually controlled depending on the setup and operating system.

Note that only one controller in the redundant pair is active at any given time. For example, if the primary Ethernet controller is active, the secondary Ethernet controller cannot be used for any other network operation.

Chapter 3. Configuring your server 35

Note: Your operating system determines the maximum number of IBM Netfinity

10/100 Fault Tolerant Adapters that you can install in your server. See the documentation that comes with the adapter for more information.

Special considerations when combining failover and hot-plug functions

If your operating system supports hot-plug PCI adapters and the optional redundant NIC adapter is installed in a hot-plug PCI slot, you can replace the NIC adapter without turning off the server — even if it is the primary Ethernet controller. Disconnecting the Ethernet cable from the primary Ethernet controller will cause the Ethernet traffic to be automatically switched to the secondary Ethernet controller. This can be very useful when a network problem is caused by faulty adapter hardware or when you want to upgrade the primary adapter hardware.

Note: If the primary adapter is hot-replaced while the Ethernet traffic is being

handled by the secondary Ethernet controller, the traffic does not automatically switch back to the primary adapter when the primary adapter comes back online. See “Configuring for failover.”

Configuring for failover

The failover feature currently is supported by OS/2, Windows NT Server, and IntraNetWare. The setup required for each operating system follows.

OS/2

Note: The OS/2 operating system does not support hot-plug operations.

1. Add the redundant NIC adapter according to the instructions provided with the adapter and in “Working with adapters” on page 53.

2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter device driver. (Refer to the ServerGuide topic.)

3. Using the MPTS Utility program, select the driver from the list and click the Edit button.

Note: Only one driver instance needs to be loaded for each redundant pair of

Ethernet controllers.

4. Change the PermaNet Server Feature keyword to TRUE and specify the Primary and Standby slots that contain the redundant pair. Refer to “System-board component locations” on page 99 for the locations and slot numbers of the PCI slots. The integrated controller is located in slot 2 (PCI bus A slot 2).

5. To enable the writing of messages to the IBMCOM\LANTRAN.LOG file when a failover occurs:

a. Copy the file PCNETOS2.EXE from the root directory of the diskette

created using the ServerGuide CDs to your hard disk.

b. Add the following statement to the CONFIG.SYS file:

Run=d:\path\PCNETOS2.EXE

where d and path are the drive and path to which you copied PCNETOS2.EXE.

6. Restart the server.

36 IBM xSeries User's Reference

The failover function is now enabled.

Windows NT Server

IBM offers hot-plug support for Windows NT Server Version 4.0. Failover can work in conjunction with hot-plug support or independently. If you are not using hot-plug support, go to “Windows NT Server failover setup” on page 38.

Windows NT Server hot-plug setup: IBM Hot Plug PCI for Windows NT Server

4.0 package is available for download from http://www.ibm.com/pc/support on the World Wide Web.

Enter the brand type of Server, click on Downloadable files and look for Hot Plug. The IBM Hot Plug PCI for Windows NT Server 4.0 package uses the Intel Desktop Management Interface (DMI) to control hot-plug support for the Ethernet controllers. The Ethernet controller in your computer is DMI compliant. Download and install the following software in the order listed:

1. IBM Failover DMI Agent

2. IBM PCI Hot Plug Solution

3. IBM Netfinity 10/100 Fault Tolerant Adapter device drivers

Note: The order of installation is important. The IBM Hot Plug for Windows NT

Server 4.0 package must be installed before the IBM Netfinity 10/100 Fault Tolerant Adapter driver is installed. If the adapter device driver is installed before the PCI Hot Plug Solution package, the adapter device driver will not recognize the hot-plug code. This happens because the adapter device driver only checks the NT registry for the Hot Plug package during installation. If the PCI Hot Plug Solution package is added after the adapter device driver is installed, the adapter must be removed and added again in order for it to detect the PCI Hot-Plug Solution code.

To install the IBM Failover DMI Agent:

1. Download the DMI EXE file from the IBM Support Web page, and extract the

files onto a diskette.

2. Insert the diskette into the diskette drive.

3. From the Start menu, select the Run option.

4. Type A:\SETUP.EXE in the Open box.

5. Click Ok. The setup wizard opens.

6. Follow the instructions given by the setup wizard until the program is installed.

7. Restart the server.

To install the IBM PCI Hot Plug Solution package:

1. Download the IBM PCI Hot Plug Services EXE file from the IBM Support Web

page, and extract the files onto a diskette.

2. Log on to Windows NT Server as a user in the Administrator group.

3. Insert the diskette into the diskette drive.

4. From the Start menu, select the Run option.

5. Type A:\SETUP.EXE in the Open box.

6. Click OK. The Setup wizard opens.

Chapter 3. Configuring your server 37

7. Follow the instructions given by the setup wizard until the program is installed.

Windows NT Server failover setup: To install the IBM Netfinity 10/100 Fault Tolerant Adapter device drivers:

1. Add the redundant NIC adapter according to the instructions provided with the adapter and in “Working with adapters” on page 53.

2. Use the ServerGuide CDs to install the AMD PCNet Ethernet Family adapter device driver. (Refer to the ServerGuide topic.)

3. Do not select the Grouping box at this point; you must first restart the server.

4. From the Windows NT Server desktop, select Control Panel, then select the Network icon, and then select the Adapters tab.

5. Highlight one of the adapters that will be in the redundant pair and then click the Properties... button.

6. Click the Grouping check box to select it. This will show the possible combinations for redundant pairs.

7. Select the adapter pair you want and then select OK. Note that the integrated Ethernet controller is located at PCI bus A, slot 2.

Two options are available for recovering from a failover condition. The options are determined by the Enable for DMI / Hot Swap Support check box. If the IBM Hot Plug PCI for Windows NT Server 4.0 package is installed, this check box will appear at the bottom of the Adapter Properties panel. If you do not have the IBM Hot Plug PCI for Windows NT Server 4.0 package installed on your server, you will not see the Enable for DMI / Hot Swap Support check box.

If the Enable for DMI / Hot Swap Support check box is not checked or is not present, traffic will automatically switch back to the primary adapter when the primary link status is restored. In this mode, the adapter cannot be hot-swapped. Users with the IBM Hot Plug PCI for Windows NT Server 4.0 package installed should check the Enable for DMI / Hot Swap Support check box.

If the Enable for DMI / Hot Swap Support check box is checked, traffic will remain on the secondary adapter until the user directs it to return to the primary adapter. This can be done after the hot-swap replacement of the primary adapter or by using the DMI interface.

8. Select Close to exit from the Network setup. When you restart the server, the failover function will be in effect.

If a failover occurs, a message is written to the NT Event Viewer log. In addition, if the Enable for DMI / Hot Swap Support check box is checked, a DMI alert will also be generated.

IntraNetWare

1. Add the redundant NIC adapter according to the instructions provided with the adapter and in “Working with adapters” on page 53.

2. Load the device driver by using the following command:

LOAD d:\path\PCNTNW.LAN PRIMARY=x SECONDARY=y

where d and path are the drive and path where the driver is located, and x and y are the PCI slot numbers where the redundant pair is located.

38 IBM xSeries User's Reference

The slot number associated with the integrated Ethernet controller can vary depending upon the configuration of the server. To determine the slot number, load the driver with no parameters. The driver will display the available slot numbers. The slot number that is greater than 10000 will be the slot number of the integrated Ethernet controller. When the slot number of the integrated Ethernet controller is determined, reload the driver with the appropriate parameters.

3. When the driver is loaded, bind it to a protocol stack.

The failover function is now enabled. If a failover occurs:

 A message is generated to the operating system console.  The custom counters for the device driver contains variables that define the

state of the failover function and the location of the redundant pair. You can use the NetWare Monitor to view the custom counters.

Note: If the primary adapter was hot-replaced while the Ethernet traffic was being

handled by the secondary Ethernet controller, the traffic does not automatically switch back to the primary adapter when the primary adapter comes back online. In this case, issue the command:

LOAD d:\path\PCNTNW SCAN

where d and path are the drive and path where the driver is located. This command causes the device driver to locate the primary adapter and switch the Ethernet traffic to it.

Chapter 4. Installing options 43

Working inside the server with power on

Your server is designed with special features that make it highly available. These features include hot-plug PCI expansion slots and hot-swap fans. You can add or replace PCI adapters (if supported by your operating system) or replace a fan that no longer functions. In the past, you would need to turn off the server and disconnect power to perform these operations. With the hot-plug features, you now can remove the cover of your server with the power on.

Your server is designed to operate safely while turned on with the cover removed. Here are some simple guidelines to follow when you work inside a server that is turned on:

 Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before

working inside the server; do not wear cufflinks while you are working inside the server.

 Do not allow your necktie to hang inside the server.  Remove jewelry, such as bracelets and loose-fitting wrist watches.  Remove items from your shirt pocket (such as pens or pencils) that could fall

into the server as you lean over it.

 Take care to avoid dropping any metallic objects, such as paper clips, hair pins,

or screws, into the server.

Handling static-sensitive devices

Attention:

Static electricity can damage electronic devices and your system. To avoid damage, keep static-sensitive devices in their static protective bag 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 on its static-protective package. (If your device is an adapter, place it component side up.) Do not place the device on your system unit cover or on a metal table.

 Take additional care when handling devices during cold weather as heating

reduces indoor humidity and increases static electricity.

44 IBM xSeries User's Reference

System reliability considerations

To help ensure proper cooling and system reliability, make sure:

 Each of the drive bays has either a drive or a filler panel installed.  Each of the power supply bays has either a power supply or a filler panel

installed.

 The cover is in place during normal operation.

Note: The front door (tower model) can be permanently removed without

affecting system reliability.

 Be sure to leave space around the server to allow the server cooling system to

work properly.

– On a tower model, leave about 127 mm (5 in.) of space around the front

and rear of the server.

– On a rack model, refer to the documentation that comes with the rack.

 The cover is removed for no longer than 30 minutes while the server is

operating.

 A removed hot-swap drive is replaced within two minutes of removal.  Cables for optional adapters are routed according to the instructions provided

with the adapters.

 A failed fan is replaced within 48 hours.

Working with adapters

You can install up to five peripheral component interconnect (PCI) adapters in the expansion connectors, called slots, on the system board of your server.

In three of the PCI slots, you can install a new PCI adapter or replace an existing PCI adapter with the same type of adapter without turning off the server power and restarting the system, if these features are supported by your operating system. These slots are sometimes called Active PCI, hot-pluggable PCI, or hot-plug PCI slots. The two remaining PCI slots support standard (non-hot-plug) PCI adapters. PCI

Your server comes with a video controller. This video controller is an integrated component on the system board. It is not in an expansion slot. The integrated video controller has super video graphics array (SVGA) technology.

The integrated video controller is not removable. If you want to disable this controller and use a video adapter instead, you can install a video adapter in an expansion slot. When you install a video adapter, the server BIOS automatically disables the integrated video controller.

The following illustration shows the location of the PCI expansion slots on the system board.

Chapter 4. Installing options 53

LEDs for hot-plug PCI slots

Each hot-plug PCI slot has three LEDs associated with it — two Attention LEDs and one Power LED.

 Power LED: This LED is on when the hot-plug PCI slot is active and has

power. An adapter must not be added to or removed from the PCI slot when the Power LED is on. When this LED is off, the PCI slot is inactive and has no power applied. An adapter can be installed when the Power LED for the PCI slot is off. Refer to your operating system documentation to determine if it supports hot-plug PCI adapters, and, if so, how to disable the hot-plug PCI slot.

 Attention LEDs: Each hot-plug PCI slot has an Attention LED that is visible

from the rear of the server and one that can be seen from inside the server. (The LEDs have the same meaning; they are duplicated to be visible from outside or inside the server.) An Attention LED flashes approximately once per second when it is on. The meaning of the Attention LEDs is defined by your operating system. Refer to your operating system documentation to determine if it supports hot-plug PCI adapters and, if so, what the Attention LEDs indicate.

The following table describes the LEDs:

Power LED Attention LED Description On Flashing The adapter requires attention. Slot still has

power applied. Do not remove or install an

adapter in the slot. Refer to your operating

system documentation for instructions. On Off Normal operation; no intervention is required. Off Flashing The adapter requires intervention. Power is

removed from the slot. An adapter can be

removed or installed in the slot. Off Off Power is removed from the slot. An adapter

can be removed or installed in the slot.

Adapter considerations

Before you continue with the adapter-installation procedure:

 Review the documentation that comes with the adapter and follow those

instructions in addition to the instructions provided in this chapter. If you need to change the switch or jumper settings on your adapter, follow the instructions that come with the adapter documentation.

 You can install full-length adapters in all expansion slots.  You can install hot-plug PCI adapters in PCI slots 3–5, if your operating system

supports this feature. Non-hot-plug PCI adapters can also be installed in these slots.

 Your server supports 5.0V and universal PCI adapters; it does not support

3.3 V adapters. Note: A universal PCI adapter supports both 3.3V and 5.0V operation.

 Your server uses a rotational interrupt technique to configure PCI adapters.

Because of this technique, you can install a variety of PCI adapters that currently do not support sharing of PCI interrupts.

 PCI slots 1 and 2 are on PCI bus A, and PCI slots 3–5 are on PCI bus B. Both

PCI buses are primary buses. The system scans PCI slots 1 through 5 to assign system resources; then the system starts (boots) the PCI devices in the following order, if the default boot precedence has not been changed: PCI slots 1 and 2, system board SCSI devices, and then PCI slots 3 through 5. See “Start Options” on page 27 for information about changing the boot precedence.

Note: The performance of the PCI adapters depends on the configuration of

adapters in your system.

Enabling hot-plug PCI support

Your server has hot-plug PCI capability. In order to enable this feature, you must install the operating system services for hot-plug PCI support code. You can obtain the operating system hot-plug PCI support code from http://www.ibm.com/pc/support on the World Wide Web.

IO-compliant statement

I2O is a new standard architecture for intelligent I/O that offloads low-level interrupts from the server processor to input/output processors (IOPs) designed specifically to handle I/O. I2O-compliant adapters can improve I/O performance in high-bandwidth applications, such as client/server processing, video, and groupware.

The xSeries 240 is intended to support I2O-compliant (deep) adapters as listed in the ServerProven program. A deep adapter is a PCI card that has an embedded input/output processor (IOP). For the deep adapter to function correctly, the following items are needed:

 An operating system service module (OSM), provided by an operating system

vendor, that supports the class of adapter (such as storage) that is being installed in the server.

 A hardware device module (HDM), provided by a PCI-card vendor.

Chapter 4. Installing options 55

Installing a hot-plug PCI adapter

Attention: All hot-plug operations must be done through the operating system

console (or supported user interface). Otherwise, the system might lock up or serious damage to the adapter or system unit might occur.

This section contains the procedure for installing a hot-plug PCI adapter. If you want to remove a hot-plug adapter, reverse the steps. If your operating system supports hot-replace PCI adapters, you can replace a failing hot-plug PCI adapter with a new adapter of the same type without turning off power to the server. If your operating system and adapter also support the hot-add feature, you can install a new adapter without turning off the power to the server.

Note: You do not need to turn off the server to install or remove a hot-plug PCI

adapter.

Before you begin:

 Read “Electrical safety” on page 42 and “Handling static-sensitive devices”

on page 44.

 Read the documentation that comes with your adapter for any special

requirements or restrictions.

 Read the documentation that comes with your operating system.

Attention: Do not remove a hot-plug adapter before performing the operating-system-defined procedure for disabling the hot-plug PCI slot that contains the adapter. Failure to do so might cause your system to lock up. Refer to your operating system documentation.

Special considerations for installing a RAID adapter

You can install an optional RAID adapter in your server to control the hot-swap hard disk drives.

To install the RAID adapter:

1. Disconnect the SCSI cable from the SCSI cable extender on the system board. See the illustration in “Installing a hot-plug PCI adapter” on page 56 for the location of the SCSI cable extender. (The other end of the SCSI cable is connected to the SCSI hard disk drive (HDD) backplane.) The Service label on the inside of the cover of your server shows cable routing for an optional RAID adapter.

2. Connect the end of the SCSI cable that you disconnected from the SCSI cable extender to the RAID adapter. The other end of the cable is connected to the SCSI HDD backplane; the drives in the hot-swap bays are now connected to the RAID adapter.

3. Connect the 2-drop SCSI cable to the SCSI cable extender on the system board, and attach the device in the non-hot-swap bay to one of the drops on the other end of the 2-drop SCSI cable. The device is attached to the integrated SCSI controller.

Refer to the documentation provided with the RAID adapter for more information about installing the adapter and configuring a disk array.

Verifying compatibility between network adapters and device drivers

Your server supports several types of network adapters. If you are having trouble with the installation or operation of a network adapter or network operating system, ensure that the network-adapter device driver supports up to four processors. Refer to your network-adapter documentation for additional information about adapter compatibility requirements.

Chapter 4. Installing options 61

Installing a microprocessor kit

Your server comes with one microprocessor installed on the processor board. If you install an additional microprocessor kit, 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. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Before you begin:

 Read “Electrical safety” on page 42 and “Handling static-sensitive devices”

on page 44.

 Thoroughly review the documentation that comes with the microprocessor,

so that you can determine whether you need to update the server basic input/output system (BIOS). The latest level of BIOS for your server is available through the World Wide Web. See Chapter 7, “Getting help, service, and information” on page 161 for the appropriate World Wide Web addresses.

 Obtain an SMP-capable operating system (optional). For a list of supported

operating systems, see http://www.ibm.com/pc/us/compat/ on the World Wide Web.

Attention: To avoid damage and ensure proper server operation when you install a new or an additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical.

Notes:

1. The illustrations in this section might differ slightly from your hardware.

2. To order additional microprocessor options, contact your IBM reseller or IBM marketing representative.

3. The microprocessor that is installed in microprocessor connector U5 is CPU or processor 1. If a microprocessor is installed in microprocessor connector U6, it is CPU or processor 2. If the server has only one microprocessor installed, that microprocessor is installed in microprocessor connector U5 and is the startup (boot) processor. If more than one microprocessor is installed, the microprocessor with the lower stepping level is the startup processor, and the microprocessor with the higher stepping level is the application processor. If both microprocessors have the same stepping level, the microprocessor installed in microprocessor connector U6 is the startup processor, and the microprocessor installed in U5 is the application processor.

Note: You can determine the stepping levels of the installed microprocessors

using the Configuration/Setup. See “System Summary” on page 22.

Installing memory-module kits

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 options called memory-module kits. Each kit contains one industry-standard, dual-inline memory module (DIMM). Your server uses a noninterleaved memory configuration.

Your server comes with a DIMM installed on the processor board in DIMM connector 4 (J1). You must install the largest DIMM in the memory connector farthest from the microprocessor (DIMM connector 4). If you install two DIMMs, you must install the second one in the memory connector closest to the microprocessor (DIMM connector 1). If you install three DIMMs, you must install the third one in DIMM connector 2. If you install four DIMMs, you must install the fourth one in DIMM connector 3.

Note: The size of the DIMMs in the other memory connectors (DIMM connectors

1, 2, and 3) does not matter. Refer to the following table for some typical memory configurations.

Table 3. Typical memory configurations

DIMM 4 DIMM 3 DIMM 2 DIMM 1

Note: Your server supports 128MB, 256MB, 512MB, and 1GB DIMMs. Your

server supports a minimum of 128MB and a maximum of 4GB of system memory. Only 133MHz, 3.3 V, 168-pin, 8-byte, 72-bit registered, synchronous-dynamic-random-access memory (SDRAM), error correcting code (ECC) with x4 configuration DIMM memory complying with PC 133 Registered DIMM Specification, Revision 1.0 or later is supported. When installed in systems using 100MHz front-side bus processors, the memory operates at 100MHz.

Before you begin:

 Read “Electrical safety” on page 42 and “Handling static-sensitive devices”

on page 44.

 Read the documentation that comes with your option.

To install a DIMM:

1. Turn off the server and peripheral devices and disconnect all external cables and power cords (see “Preparing to install options” on page 46); then remove the cover. See “Removing the left-side cover (tower model)” on page 48 or “Removing the cover (rack model)” on page 49.

2. Locate the DIMM connectors on the processor board. Determine the DIMM connector into which you will install the DIMM. (See the notes at the beginning of this procedure.)

3. Touch the static-protective package containing the DIMM to any unpainted metal surface on the server. Then, remove the DIMM from the package.

Note: To avoid breaking the retaining clips or damaging the DIMM connectors,

handle the clips gently.

4. Install the DIMM:

a. Turn the DIMM 1 so that the pins align correctly with the connector 5. b. Insert the DIMM into the connector by pressing on one edge of the DIMM

and then on the other edge of the DIMM. Be sure to press straight into the connector. Be sure that the retaining clips 2 snap into the closed positions.

c. Make sure the retaining clips are in the closed position. 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.

d. Repeat these steps for each DIMM that you install.

Attention:

Installing or removing DIMMs changes the configuration information in the server. When you restart the server, the system displays a message indicating that the memory configuration has changed.

 If you installed additional memory, start the Configuration/Setup Utility

program and select Save Settings.

 If you just replaced a failed DIMM, you must start the Configuration/Setup

Your server contains hardware that lets you replace a failed hard disk drive without turning off the server. Therefore, you have the advantage of continuing to operate your system while a hard disk drive is removed or installed. These drives are known as hot-swappable drives. They are also referred to as hot-swap drives.

Each hot-swap drive that you plan to install must have a hot-swap-drive tray attached. The drive must have a single connector attachment (SCA) connector. Hot-swap-drive trays come with the hot-swap drives.

 Your server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive and a

preinstalled IDE CD-ROM drive.

 Bays A and B come without a device installed. These bays are for 5.25-inch,

half-high, removable-media drives, such as tape backup drives. Bays A and B can be combined into a single full-high bay.

 Your server supports only one diskette drive.

Note: The EMI integrity and cooling of the server are both protected by having

bays A and B covered or occupied. When you install a drive, save the filler panel from the bay, in case you later remove the drive and do not replace it with another.

 If you are installing a device with a 50-pin connector in one of the non-hot-swap

bays (bays A and B), you need a 68-pin to 50-pin converter. To order the converter, contact your IBM reseller or IBM marketing representative.

 Your server supports six slim (1-inch) or three half-high (1.6-inch), 3.5-inch

hot-swap hard disk drives in the hot-swap bays.

 The hot-swap bays connect to a SCSI backplane. This backplane is the

printed circuit board behind the bay. The backplane supports up to six hard disk drives.

 The diskette drive uses 1 MB and 2 MB diskettes. For optimum use,

format 1 MB diskettes to 720 KB and format 2 MB diskettes to 1.44 MB.

SCSI drives

Some drives have a special design called small computer system interface, or SCSI. This design allows you to attach multiple drives to a single SCSI channel.

Notes:

1. Any information about SCSI drives also applies to other SCSI devices, such as

tape drives.

2. If you plan to install both internal and external SCSI devices, you must follow

the instructions in “Connecting external options” on page 90, in addition to the instructions in this section.

A 16-bit (wide) SCSI cable connects the SCSI HDD (hard disk drive) backplane to an integrated SCSI controller on the system board. An additional 16-bit 2-drop SCSI cable is shipped, disconnected, inside your server. It is folded and restrained with a cable clamp to the side of the power supply housing.

If you want to install a device in one of the non-hot-swap bays, you can either:

 Install an additional SCSI adapter and use the 2-drop SCSI cable to attach the

device to that adapter.

 Install a RAID adapter as follows:

SCSI IDs

Each SCSI device that is connected to an individual channel of a SCSI controller needs a unique identification (ID) so that the controller can identify the devices and ensure that different devices do not attempt to transfer data at the same time. If you need to set IDs for SCSI devices, refer to the instructions that come with those devices.

Your server automatically sets SCSI IDs for hot-swap hard disk drives. The SCSI ID assigned to each hot-swap bay is shown on your server beside the bay and in the illustrations in “Internal drive bays” on page 67. The server uses the hard disk drive SCSI IDs to send status information to the indicator lights above each hot-swap bay.

The SCSI backplane in the server supports up to six hot-swap bays. The processing sequence for SCSI devices proceeds from the lowest SCSI ID to

the highest (0 to 6, then 8 to 15).

Chapter 4. Installing options 69

Termination (internal SCSI devices)

SCSI buses must be terminated at each end. The ends of the SCSI buses in your server are already terminated.

All the hot-swap drives in your server have automatic termination, and the SCSI controller provides termination at the other end of the SCSI bus.

You must disable termination on any SCSI devices that you install in the non-hot-swap bays. Refer to the information that come with the SCSI device for instructions about setting device jumpers or switches that control termination.

Preinstallation steps (all bays)

Before you install drives in your server, verify that you have all the cables and any other equipment specified in the documentation that comes with the internal drive. You might also need to perform certain preinstallation activities. Some of the steps are required only during the initial installation of an option.

Before you begin:

 Read “Electrical safety” on page 42 and “Handling static-sensitive devices”

on page 44.

 Read the documentation that comes with the internal drive.

1. Choose the bay in which you want to install the drive.

2. Check the instructions that come with the drive to see if you need to set any switches or jumpers on the drive.

3. To install the drive, go to “Installing a non-hot-swap drive” on page 71 or “Installing a drive in a hot-swap bay” on page 73.

Installing a drive in a hot-swap bay

The hot-swap drive bays support hot-swap drives only. This section contains the procedure for installing a hot-swap hard disk drive. If you

want to remove a drive, reverse the following steps.

Notes:

1. To minimize the possibility of damage to the hard disk drives when you are

installing a hard disk drive in a rack model, install the rack model in the rack before installing the hard disk drives.

2. You do not have to turn off the server to install hot-swap drives in these bays.

However, you must turn off the server when performing any steps that involve installing or removing cables.

Before you begin:

 Read “Electrical safety” on page 42 and “Handling static-sensitive devices”

on page 44.

 Read the documentation that comes with your drive.  If your server has a RAID adapter installed, review the documentation that

comes with your RAID adapter for information about the RAID adapter and disk-array configuration.

 Prepare the drive for installation (see “Preinstallation steps (all bays)” on

To install a drive in a hot-swap drive bay:

1. If your server is a tower model, unlock and open the server door.

Attention: To maintain proper system cooling, do not operate the server for more than two minutes without either a drive or a filler panel installed in each bay.

2. Remove the filler panel 2 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.

Note: If you are installing a half-high hard disk drive, you will need to remove

two adjacent filler panels. The two filler panels should be from either the top pair of bays, the middle pair of bays, or the bottom pair of bays.

3. If your hard disk drive is not installed on the drive tray 5, place the drive in

the drive tray and, being careful not to over-tighten the screws, attach the drive to the tray using the four screws provided with the option kit.

4. Install the hard disk drive 3 in the hot-swap bay:

a. Ensure the tray handle 6 is open (that is, perpendicular to the drive). b. Align the drive/tray assembly so that it engages the guide rails in the bay.

c. Gently push the drive/tray assembly into the bay until the drive connects to

the backplane.

d. Push the tray handle to the right until it locks.

5. If you installed a half-high hard disk drive, install a filler panel 1 in the gap

above the drive:

a. Locate the smaller filler panel 1 that is designed for use with half-high

drives. It is stored on the slim-high filler panel 2 that you removed earlier in this procedure.

b. Pull the smaller filler panel off the filler panel.

c. Gently push the filler panel 1 into place in the gap above the drive.

6. Check the hard disk drive status indicators to verify that the hard disk drives

are operating properly. See “Identifying problems using status LEDs” on page 151 for details.

7. If your server is a tower model, close and lock the server door.

Note: If your server has a RAID adapter installed, you must reconfigure your

disk arrays after installing hard disk drives.

Chapter 4. Installing options 75

Replacing a drive in a hot-swap bay

You do not have to turn off the server to remove a drive from a hot-swap bay.

Attention:

1. Before you remove a hot-swap hard disk drive that is not defective, back up all important data.

2. To avoid damage to a hard disk drive, Do not remove the drive from the hot-swap bay until it has had time to spin down (approximately 30 seconds). Handle the drive carefully.

3. Before you remove a hot-swap drive, make sure it is defective. If you partially or completely remove a good drive instead of a defective one your server might lose valuable data.

This situation is especially relevant if your server has a RAID adapter installed and you assigned RAID level 1 or 5 to the logical drives in your disk array. The RAID adapter can rebuild the data that you need, provided that certain conditions are met. Refer to the information provided with the RAID adapter for further details.

Before you begin:

Updating device records and reconfiguring the server

When you start your server for the first time after you add or remove an internal option or an external SCSI device, you might see a message telling you that the configuration has changed.

Some options have device drivers that you need to install. Refer to the documentation that comes with your option for information about installing any required device drivers.

If you have more than one microprocessor installed, you might want to upgrade your operating system. Refer to ServerGuide topic. If you have installed or removed hard disk drives and your server has a RAID adapter installed, refer to the documentation provided with your RAID adapter for information about reconfiguring your disk arrays.

Run the Configuration/Setup Utility program to save the new configuration information. See Chapter 3, “Configuring your server.”

Connecting external options

Before you begin:

 Read “Electrical safety” on page 42 and “Handling static-sensitive devices”

on page 44.

 Read the documentation that comes with your options.

Connecting external SCSI devices

You can attach a SCSI storage expansion enclosure to your server.

Cabling requirements

The SCSI controller in your server has one channel that can be used to attach external devices. This channel is connected to the SCSI connector on the back of the server and supports 14 unique SCSI IDs. To select and order the correct cables for use with external devices, contact your IBM reseller or IBM marketing representative.

For information about the maximum length of SCSI cable between the terminated ends of the cable, see ANSI SCSI Standards:

 X3.131-1986 (SCSI)  X3.131-1994 (SCSI-2)  X3T10/1071D

Adhering to these standards ensures that your server operates properly.

Setting SCSI IDs for external devices

Each SCSI device that is connected to a SCSI controller must have a unique SCSI ID, so that the SCSI controller can identify the devices and ensure that different devices do not attempt to transfer data at the same time. SCSI devices that are connected to different SCSI controllers can have duplicate SCSI IDs. The SCSI controller uses one of the SCSI IDs; the default SCSI ID for the SCSI controller is

7. See “SCSI IDs” on page 69 and refer to the instructions that come with the SCSI devices for more information about setting a SCSI ID.
