The ServerGuide program requires a supported IBM server with an enabled startable (bootable) CD-ROM drive. In addition to the ServerGuide Setup and Installation CD, you must have your operating-system CD to install your operating system.

Chapter 2. Configuring your server 13

The ServerGuide program has the following features:

v Sets system date and time. v Detects the SCSI RAID adapter or controller and runs the SCSI RAID

configuration program.

v Updates the licensed internal code (firmware) level without diskettes. v Checks the system BIOS code and microcode (firmware) levels of supported

options to determine whether a later level is available from the CD. You can perform updates without using diskettes.

v Provides the Performance Optimizer program to easily tune your SCSI RAID

adapter settings for your server environment.

v Detects installed hardware options and provides updated device drivers for most

adapters and devices.

v Creates a setup-replication diskette for replicating setup selections for other

servers of the same model.

v Provides diskette-free installation for supported operating systems. v Provides a replicated installation path for multiple installations of supported

operating systems.

v Includes an online README file with links to tips for your hardware and

operating-system installation.

Setup and configuration overview

When you use the ServerGuide Setup and Installation CD, you do not need setup diskettes. You can use the CD to configure any supported IBM server model. The ServerGuide program checks your system BIOS, service processors, and other system hardware to determine if system updates are available. The setup program provides a list of tasks that are required to set up your server model. On SCSI RAID servers, you can run the SCSI RAID configuration program to create logical drives.

Note: Features and functions can vary slightly with different versions of the

ServerGuide program.

When you start the ServerGuide Setup and Installation CD, the program performs the following tasks:

v The ServerGuide program prompts you for your language, country, and keyboard

layout. (This information is stored and later passed to the operating-system installation program.)

v The ServerGuide program displays choices for running the configuration

programs. For example: – The Express Configuration method runs the required programs for your

server, based on the hardware that is detected.

– The Custom Configuration method displays all programs that are available for

your server, and you decide which programs to run.

– The Replicated Configuration method provides the option of duplicating your

setup selections to other servers that are the same model.

v If you select the Custom Configuration method, the following features are

optional. If you select the Express Configuration method, some or all of these features are run, depending on the hardware that is detected:

– The Set Date and Time feature is provided so that you do not have to use the

Configuration/Setup Utility program to access these settings.

14 IBM xSeries 205 Type 8480: Hardware Maintenance Manual and Troubleshooting Guide

– The Clear Hard Disks feature is provided so you can delete all partitions on all

hard disk drives. If the server has a SCSI RAID adapter installed, you can select to restore the configuration on the SCSI RAID adapter to the factory default settings.

– The ServerGuide program checks the system BIOS code and microcode

(firmware) levels for supported options and then checks the CD for a newer level. The CD content might be newer than the BIOS code and firmware level. The ServerGuide program can perform a flash update of the BIOS code and supported microcode (firmware) options without using diskettes.

– The SCSI RAID configuration program starts, leading you through the entire

configuration process.

– The Performance Optimizer program easily tunes your server for your

environment.

v The ServerGuide program displays a confirmation summary, so that you will

know when you have completed all the required tasks. Then, you are ready to install your operating system.

Notes:

1. Plug and Play adapters are configured automatically. Non-Plug and Play adapters might require switch settings, additional device drivers, and installation after the operating system is installed. See the documentation that comes with the adapter.

2. Diagnostics for your server come in BIOS code or on a separate diagnostics CD.

Typical operating-system installation

You can use the ServerGuide program to shorten your installation time. The ServerGuide program provides the device drivers that are required for your hardware and for the operating system that you are installing. This section describes a typical ServerGuide operating-system installation.

Note: Features and functions can vary slightly with different versions of the

ServerGuide program.

1. After you have completed the setup process, the operating-system installation program starts. (You will need your operating-system CD to complete the installation.)

2. The ServerGuide program stores information about the server model, service processor, hard disk drive controllers, and network adapters. Then, the program checks the CD for newer device drivers. This information is stored and then passed to the operating-system installation program.

3. With some operating-system installations, you can create an operating-system-replication diskette for setting up additional servers. This diskette contains the Internet protocol (IP) address, server name, and other selections.

4. If you are installing the operating system from diskette, the ServerGuide program lists the diskettes that you must create and the optional diskettes that you might want to create. The diskettes that you can create are the device-driver diskettes for the installed adapters or controllers.

5. The ServerGuide program prompts you to insert your operating-system CD and restart the server. At this point, the installation program for the operating system takes control to complete the installation.

Chapter 2. Configuring your server 15

Setting up or updating multiple servers

You can use the ServerGuide program to create diskettes that help you set up or update multiple servers. You can modify information on the diskettes as you use them to set up or update other servers.

Note: Availability and function can vary by server model and by the hardware that

is installed.

You can create a setup-replication diskette, which contains your hardware configuration selections. Use this diskette to replicate selections to other servers that are of the same model.

You can create an operating-system-replication diskette, which contains information that you need to complete multiple installations. Not all operating systems support operating-system-replication diskettes.

Installing your operating system without ServerGuide

If you have already configured the server hardware and you decide not to use the ServerGuide program to install your operating system, complete the following steps to download the latest operating-system installation instructions from the IBM Support Web page:

1. Go to http://www.ibm.com/pc/support/.

2. Under Browse, click Servers.

3. From the Family drop-down list, select your server model.

4. If NOS installation instructions are available for your server model, OS

installation is in the list in the upper-left corner of the Web page. Click OS installation and select the instructions for your operating system.

Configuring the Gigabit Ethernet controller

The server comes with an integrated Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides full duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN). You do not need to set any jumpers or configure the Ethernet 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. The device drivers are provided on the Device Drivers and IBM Enhanced Diagnostics CD.

When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10-Mbps, 100-Mbps, or 1000-Mbps) on the network and then sets the controller to operate at the appropriate rate. In addition, if the Ethernet ports that your server is connected to support auto-negotiation, the Gigabit Ethernet controller will set the appropriate duplex state. That is, the Ethernet controller will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

For information about configuring your Ethernet controller, see the Device Drivers and IBM Enhanced Diagnostics CD that comes with your server. For updated information about configuring your Ethernet controller, go to the IBM Support Web site at http://www.ibm.com/pc/support/ and navigate to the area for your specific server type. From this area you can download documentation, the most current

16 IBM xSeries 205 Type 8480: Hardware Maintenance Manual and Troubleshooting Guide

device drivers for your server, and software that supports advanced networking functions. After downloading, run the downloaded program launch.exe.

You Ethernet controller supports optional modes, such as teaming, priority packets, load balancing, fault tolerance, and virtual LANs, which provide higher performance, security, and throughput for your server. These modes apply to the integrated Ethernet controller and to the controllers on supported Ethernet adapters.

Chapter 3. Diagnostics

This section provides basic troubleshooting information to help you resolve some common problems that might occur with your server.

If you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance”, on page 115 for more information.

General checkout

The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD. These programs provide the primary methods of testing the major components of the server.

If you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

A failed system might be part of a shared DASD cluster (two or more systems sharing one or more external storage devices). Before you run diagnostics, verify that the failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

v The system is identified as part of a cluster. v One or more external storage units are attached to the system and at least one

of the attached storage units is also attached to another system or unidentifiable source.

v One or more systems are located near the failing system.

If the failing system is suspected to be part of a shared DASD cluster, you can run all diagnostic tests except the diagnostic tests that test the storage unit (DASD residing in the storage unit) or the storage adapter attached to the storage unit.

Notes:

1. For systems that are part of a shared DASD cluster, run one test at a time in looped mode. Do not run all tests in looped mode, because this could enable the DASD diagnostic tests.

2. If multiple error codes are displayed, diagnose the first error code that is displayed.

3. If the computer stops with a POST error, go to “POST error codes” on page 95.

4. If the computer stops and no error is displayed, go to “Undetermined problems”

on page 106.

5. For power supply problems, see “Power checkout” on page 29.

6. For safety information, see “Safety information” on page 117.

7. For intermittent problems, check the error log.

Small computer system interface messages

If you receive a SCSI error message, see “Diagnostic error codes” on page 89.

Note: If your server does not have a hard disk drive, ignore any message that

indicates that the BIOS is not installed.

Diagnostic programs and error messages

The server diagnostic programs are stored on the IBM Enhanced Diagnostics CD. These programs are the primary method of testing the major components of your server.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when the diagnostic programs are run.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where: fff is the three-digit function code that indicates the function being

tested when the error occurred. For example, function code 089 is for the microprocessor.

ttt is the three-digit failure code that indicates the exact test failure that

was encountered. (These codes are for trained service personnel; see “Diagnostic error codes” on page 89).

iii is the three-digit device ID. (These codes are for trained service

personnel; see “Diagnostic error codes” on page 89).

date is the date that the diagnostic test was run and the error recorded. cc is the check value that is used to verify the validity of the

Recovering from a POST/BIOS update failure

If power to your server is interrupted while POST/BIOS is being updated (flash update), your server might not restart correctly. If this happens, perform the following procedure:

1. Turn off the server and all attached devices.

2. Unplug all power cords from electrical outlets and remove the server cover and the support bracket. See the Option Installation Guide for instructions.

3. Locate the boot block and password check jumpers on the system board, removing any adapters that impede access to the jumpers. See “System and PCI extender boards” on page 35 for the location of the boot block and password check jumpers.

4. Move the jumper to the adjacent pair of jumper pins.

5. Replace any adapters that were removed and replace the support bracket and the cover. See the Option Installation Guide for instructions. Reconnect the power cords for the server and monitor to electrical outlets.

6. Insert the POST/BIOS update (flash) diskette into drive A, and turn on the server and monitor.

7. After the update session completes, remove the diskette from the diskette drive, and turn off the server and monitor.

8. Unplug all power cords from electrical outlets, and remove the cover.

9. Remove any adapters that impede access to the boot block and password check jumpers.

10. Replace the boot block and password check jumpers to their original positions.

11. Replace any adapters that were removed.

12. Replace the cover, and reconnect all cables that were disconnected.

13. Turn on the server to restart the operating system.

Power checkout

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually a short circuit will cause the power subsystem to shut down because of an overcurrent condition.

A general procedure for troubleshooting power problems is as follows:

1. Turn off the server and disconnect all ac power cords.

2. Check for loose cables in the power subsystem. Also check for short circuits, for example, if there is a loose screw causing a short circuit on a circuit board.

3. Remove adapters and disconnect the cables and power connectors to all internal and external devices until the server is at the minimum configuration required to start the server (see “Minimum operating requirements” on page 95).

4. Reconnect all ac power cords and turn on the server. If the server starts up successfully, replace adapters and devices one at a time until the problem is isolated. If the server does not start up from the minimal configuration, replace FRUs of minimal configuration one at a time until the problem is isolated.

To use this method, it is important to know the minimum configuration required for a system to start (see page 95).

Chapter 3. Diagnostics 29

Troubleshooting the Ethernet controller

This section provides troubleshooting information for problems that might occur with the 10/100/1000 Mbps Ethernet controller.

Network connection problems

If the Ethernet controller cannot connect to the network, check the following conditions: v Make sure that the cable is installed correctly.

The network cable must be securely attached at all connections. If the cable is attached but the problem remains, try a different cable.

If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps, you must use Category 5 or higher cabling.

v Determine whether the hub supports auto-negotiation. If it does not, try

configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.

v Check the Ethernet controller LEDs on the operator information panel and on the

rear of the server. These LEDs indicate whether a problem exists with the connector, cable, or hub.

– The Ethernet transmit/receive activity LED, on the operator information panel,

is lit when the Ethernet controller sends or receives data over the Ethernet Network. If the Ethernet transmit/receive activity LED is off, make sure that the hub and network are operating and that the correct device drivers are installed.

– The Ethernet link status LED, on the rear of the server, is lit when the

Ethernet controller receives a LINK pulse from the hub. If the LED is off, there might be a defective connector or cable or a problem with the hub.

v Make sure that you are using the correct device drivers which are supplied with

your server.

Installation guidelines

Before you begin to install options in your server, read the following information: v Read the handling guidelines in “Handling static-sensitive devices”, and read the

safety statements in “Safety information” on page 117. These guidelines will help you work safely with your server and options.

v Make sure that you have an adequate number of properly grounded electrical

outlets for your server, monitor, and other options that you intend to install.

v Back up all important data before you make changes to disk drives. v Have a small, flat-blade screwdriver available. v Before accessing the inside of the IBM Eserver xSeries 205 Type 8480 server,

rotate the two front stabilizing feet a quarter turn towards the server, so they do not break. Before placing the server in an upright position, rotate the two front feet a quarter turn outward from the server. See “Moving the stabilizing feet” on page 39.

v For a list of supported options for your server, go to

http://www.ibm.com/pc/support/ on the World Wide Web.

System reliability considerations

To help ensure proper system cooling and system reliability, make sure that: v Each of the drive bays has a drive or a filler panel and electromagnetic

compatibility (EMC) shield installed.

v There is adequate space around the server to allow the server cooling system to

work properly. Leave approximately 51 mm (2 in.) of open space around the front and rear of the server. Do not place objects in front of the fans.

v You have followed the instructions for cabling provided with optional adapters. v You have replaced a failed fan as soon as possible.

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 packages until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

v Limit your movement. Movement can cause static electricity to build up around

you.

v Handle the device carefully, holding it by its edges or its frame. v Do not touch solder joints, pins, or exposed printed circuitry. v Do not leave the device where others can handle and possibly damage the

device.

v While the device is still in its static-protective package, touch it to an unpainted

metal part of the server for at least 2 seconds. (This drains static electricity from the package and from your body.)

v Remove the device from its package and install it directly into the server without

setting it down. If it is necessary to set the device down, place it in its static-protective package. Do not place the device on the server cover or on a metal table.

v Take additional care when handling devices during cold weather because heating

reduces indoor humidity and increases static electricity.

Cabling a RAID adapter or single SCSI channel using one hot-swap drive SCSI backplane

You can install an optional RAID adapter in your server to control the internal hot-swap hard disk drives. The illustrations in this section show the cabling for internal hot-swap hard disk drives. You can also cable a RAID adapter to external hard disk drives. See your RAID adapter option documentation for complete instructions for installing a RAID adapter in your server and for additional information about RAID adapters.

Chapter 4. Installing options 45

One end of the SCSI cable is attached to the connector on the standard SCSI backplane, and the other end is attached to the internal SCSI channel connector on the PCI extender board or RAID adapter.

If you are connecting the server to more than two SCSI channels, you might need to purchase additional SCSI cables. Consult your IBM marketing representative or reseller for additional information about the number and types of cables that your server configuration requires.

The following procedure describes the single-channel cable routing that is necessary when you install a RAID adapter. The illustrations in this section are examples. The cabling that you use for your server depends on your system configuration.

Notes:

1. See the documentation that comes with your adapter for any cabling instructions.

2. Cable identifiers are printed on the cables that come with your server and options. Use these identifiers to connect the cables to the correct connectors. For example, the hard disk drive cables are labeled “HDD option.”

Complete the following steps to cable a single SCSI channel on an installed RAID adapter using the standard hot-swap drive SCSI backplane:

1. Determine the number of SCSI channels that you want to use on the RAID adapter.

2. Review the information in “Installation guidelines” on page 38 and “Safety information” on page 117.

3. Turn off the server and peripheral devices and disconnect all power cords and external cables; then, remove the side cover (see “Removing the side cover” on page 40).

4. If your server comes with a SCSI connector on the PCI extender board, disconnect the SCSI cable from the internal SCSI connector on the PCI extender board.

Attention: When you route the SCSI cable, observe these precautions:

v Do not block the ventilated space in front of the fan assembly. v Do not route the SCSI cable over the memory board assembly.

5. Route the SCSI cable from the backplane on the hot-swap drive cage (bays 5 to

7) to the internal channel connector on the RAID adapter.

48 IBM xSeries 205 Type 8480: Hardware Maintenance Manual and Troubleshooting Guide

Before installing a drive in bays 1, 2, 3, or 4, do the following:

1. Read “Safety information” on page 117, “Handling static-sensitive devices” on page 38, and the documentation that comes with your drive.

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

3. Check the instructions that come with the drive to see if you need to set any switches or jumpers on the drive. If you are installing a SCSI device, be sure to set the SCSI ID for that device.

Power and signal cables for internal drives

Your server uses cables to connect IDE and SCSI devices to the power supply and to the system board. The following cables are provided:

v Four-wire power cables connect the drives to the power supply. At the end of

these cables are plastic connectors of various sizes that can be attached to different drives.

v Flat signal cables, also called ribbon cables, connect IDE, SCSI, and diskette

drives to the system board. Two or three sizes of ribbon cables come with your server:

– The wider IDE signal cable has two or three connectors.

- If the cable has three connectors, one of these connectors is attached to the drive, one is a spare, and the third is attached to the primary or secondary IDE connector on the system board.

- If the cable has two connectors, one of these connectors is attached to the hard disk drive, and the other is attached to the primary or secondary IDE connector on the system board.

Note: The CD-ROM drive is attached to an ATA 66 signal cable. The hard

disk drive is attached to an ATA 100 signal cable. ATA 66 and ATA 100 signal cables are color-coded. The blue connector attaches to the system board. The black connector attaches to the primary device. If the cable has a gray middle connector, it attaches to the secondary device. If you are installing a hard disk drive, you must change the switch setting on the CD-ROM drive to secondary and change the connector used for the CD-ROM drive to the gray middle connector.

– The narrower signal cable has two connectors, one to attach to the diskette

drive, and the other to attach to the connector (FDD1) on the system board.

– If your server comes with a SCSI connector on the extender board and SCSI

hard disk drive, an Ultra160 twisted ribbon cable connects the internal Ultra160 SCSI hard disk drive to the SCSI connector on the PCI extender board. This cable has two additional connectors for attaching more internal SCSI devices.

To locate connectors on the system board, see “System board internal cable connectors” on page 36.

Review the following information before connecting power and signal cables to internal drives:

v The drives that are preinstalled in your server come with power and signal cables

attached. If you replace any drives, remember which cable is attached to which drive.

v When you install a drive, ensure that the drive connector at one end of the signal

cable is connected to the drive and that the drive connector at the other end is connected to the system board.

Chapter 4. Installing options 49

v If you have only one IDE device on a cable, it must be set as a primary device. v If two IDE devices are used on a single cable, one must be designated as the

primary device and the other as the secondary device; otherwise, the server might not recognize some of the IDE devices. The primary and secondary designation is determined by switch or jumper settings on each IDE device.

v If two IDE devices are on a single cable and only one is a hard disk drive, the

hard disk drive must be set as a primary device.

v You must also set the SCSI ID for any SCSI device that you install in your server.

Each SCSI device has its own methods and considerations for setting the SCSI ID. See the instructions that come with the SCSI device for details about setting the SCSI ID for the SCSI device.

Installing a hot-swap hard disk drive in bay 5, 6, or 7

If your server is a hot-swap model, you can replace a failed hard disk drive without turning off the server. Therefore, you can continue to operate your server while a hard disk drive is removed or installed. To do this, you must install a hot-swap hard disk drive. If a hot-swap disk drive is connected to an optional hot-swap RAID controller and if your hot-swap drive becomes defective, the RAID controller can rebuild the data from that drive onto another hot-swap drive. See the information that comes with your RAID controller for details.

Each hot-swap drive has a green hard disk drive activity LED and an amber hard disk drive status LED. When the hard disk drive activity LED is flashing, the controller is accessing the hard disk drive. When this occurs, the SCSI activity LED on the front of the server is also lit. The hard disk drive activity LED is illustrated and described in the User’s Guide. If the hard disk drive status LED for a drive is lit continuously, that individual drive is faulty and requires replacement. When the hard disk drive status LED indicates a drive fault, you can replace a hot-swap drive without turning off the server.

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

The hot-swap bays are connected to a SCSI backplane. This backplane is the printed circuit board behind the bay. The backplane controls the SCSI IDs for the hot-swap drives.

The following illustration shows the hot-swap-drive backplane component locations, as viewed from the front of the server.

Serial connectors

Your server has two standard 9-pin D-shell serial connectors: Serial connector 1 and Serial connector 2. See “System board external connectors” on page 37 for the location of this connector.

Gigabit Ethernet port

Your server comes with an integrated Gigabit Ethernet controller. This controller provides an interface for connecting to 10-Mbps, 100-Mbps, or 1000-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

Activity LED

(green)

To access the Ethernet port, connect a Category 3, 4, or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of your server.

Note: The 100BASE-TX/1000BASE-T Fast Ethernet standard requires that the

cabling in the network be Category 5 or higher.

Link LED (green)

The Ethernet (RJ-45) connector has two LEDs. The Ethernet-link status LED is on the left. When this green light is on, there is an active connection on the Ethernet port. The Ethernet transmit/receive activity LED is on the right. When this amber LED is on, there is activity between the server and the network. These LEDs have the same functions as the Ethernet-link status LED and the Ethernet transmit/receive activity LED on the rear of the server (see the User’s Guide).

Configuring the Gigabit Ethernet controller

The Ethernet controller is a PCI Plug and Play device. You do not need 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. The device drivers are provided on the Device Drivers and IBM Enhanced Diagnostics CD.

When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps, 100 Mbps, or 1000 Mbps) on the network and then sets the controller to operate at the appropriate rate. In addition, if the Ethernet ports that your server is connected to support auto-negotiation, the Gigabit Ethernet controller will set the appropriate duplex state. That is, the Ethernet controller will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX/1000BASE-T), half duplex (HDX), or full duplex (FDX). The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

Chapter 4. Installing options 63

High-performance Ethernet modes

Your Ethernet controller supports optional modes, such as teaming, load balancing, fault tolerance, and virtual LANs, which provide higher performance, security, and throughput for your server. These modes apply to the integrated Ethernet controller and to the controllers on supported Ethernet adapters.

Universal Serial Bus (USB) connectors

Your server has two Universal Serial Bus (USB) 2.0 connectors for optional telephony and multimedia devices. USB 2.0 devices configure automatically with Plug and Play technology.

Notes:

1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB 2.0 connectors and devices will be disabled during the power-on self-test.

2. If you install a USB keyboard that has a mouse connector, the USB keyboard emulates a mouse, and you will not be able to disable the mouse settings in the Configuration/Setup Utility program.

USB cables

Use a 4-pin USB cable to connect external devices to USB connectors.

USB 2.0 technology transfers data at up to 128 megabits per second (Mbps) with a maximum of 127 external devices and a maximum signal distance of 5 meters (16 ft) per segment. You must use devices that support USB 2.0 in order to obtain this maximized data transfer rate.

Audio connectors

The audio connectors are used to connect external audio equipment to your server.

Line out

This connector is used to send audio signals from the server to external devices, such as powered speakers with built-in amplifiers, headphones, multimedia keyboards, or the audio Line in connector on a stereo system.

Chapter 6. Symptom-to-FRU index

This index supports xSeries 205 servers.

Notes:

1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms.

2. For IBM devices not supported by this index, refer to the manual for that device.

3. Always start with “General checkout” on page 21.

The symptom-to-FRU index lists symptoms, errors, and the possible causes. The most likely cause is listed first. Use this symptom-to-FRU index to help you decide which FRUs to have available when servicing the computer.

The first column of the two-column tables in this index lists error codes or messages, and the second column lists one or more suggested actions or FRUs to replace. Take the action (or replace the FRU) suggested first in the list of the second column, then try the server again to see if the problem has been corrected.

Note: Try reseating a suspected component or reconnecting a cable before

replacing the component.

The POST BIOS code displays POST error codes and messages on the screen.

Beep symptoms

Beep symptoms are short tones or a series of short tones separated by pauses (intervals without sound). See the examples in the following table.

Beeps Description 1-2-3

4 Four continuous beeps
