Chapter 3. Diagnostics

This chapter provides basic troubleshooting information to help solve some common problems that might occur with the computer.

If you cannot locate and correct the problem using the information in this section, see Appendix A, “Getting help and technical assistance,” on page 123 for more information.

General checkout

Follow the checkout procedure for diagnosing hardware problems. Review the following information before performing the checkout procedure:

v Read Appendix B, “Safety information,” on page 125. v The computer diagnostic programs are stored on the IBM Enhanced Diagnostics

CD. These programs provide the primary methods of testing the major components of the computer. If you are not sure 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 correctly.

v When you run the diagnostic programs, a single problem might cause several

error messages. If you receive several error messages, correct the cause of the first error message. The other error messages might not occur the next time you run the diagnostic programs.

v Before running the diagnostic programs, you must determine whether the failing

computer is part of a shared hard disk drive cluster (two or more servers sharing external storage devices). If you suspect that it is part of a cluster, you can run all diagnostic programs except the ones that test the storage unit (that is, a hard disk drive in the storage unit) or the storage adapter that is attached to the storage unit. The failing server might be part of a cluster if any of the following conditions is true:

– The customer identifies the failing server as part of a cluster. – One or more external storage units are attached to the failing server and at

least one of the attached storage units is also attached to another server or unidentifiable device.

– One or more servers are located near the failing server.

Important:

1. For servers that are part of a shared hard disk drive cluster, run one test at a time. Do not run any suite of tests, such as “quick” or “normal” tests, because this could enable the hard disk drive diagnostic tests.

2. If more than one error code is displayed, correct the first error. The other error codes might not occur the next time you run the diagnostic programs.

3. If the server is suspended and a POST error code is displayed, see “POST error codes” on page 85.

4. If the server is suspended and no error message is displayed, see “Error symptoms” on page 95 and “Undetermined problems” on page 113.

5. For information about power-supply problems, see “Power checkout” on page

22.

6. For intermittent problems, check the error log; see “Diagnostic programs and error messages” on page 16.

Complete the following steps to perform the checkout procedure:

001 IS THE SERVER PART OF A CLUSTER?

YES. Schedule maintenance for the system. Shut down all systems related

to the cluster. Run the storage test.

NO. Go to step 002.

002 IF THE SERVER IS NOT PART OF A CLUSTER:

1. Turn off the server and all external devices.

2. Check all cables and power cords.

3. Set all display controls to the middle position.

4. Turn on all external devices.

5. Turn on the server.

6. Record any POST error messages that are displayed on the screen. If an error is displayed, look up the first error in the “POST error codes” on page 85.

7. Check the system-error log.

Note: The system-error log is available only with the Remote

Supervisor Adapter II.

If an error was recorded by the computer, see Chapter 6, “Symptom-to-FRU index,” on page 83.

8. Start the diagnostic programs.

9. Check for the following responses:

v One beep v Readable instructions or the main menu

DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?

003

NO. Find the failure symptom in Chapter 6, “Symptom-to-FRU index,” on

page 83.

YES. Run the diagnostic programs (see “Starting the diagnostic programs

and viewing the test log” on page 17). If you receive an error, see Chapter 6, “Symptom-to-FRU index,” on page

83.

If the diagnostic programs were completed successfully and you still suspect a problem, see “Undetermined problems” on page 113.

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

113).

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

To use this method, you must know the minimum configuration that is required for the server to start (see page 103).

Chapter 4. Installing options

This chapter provides instructions for installing or replacing hardware options in your computer. For a list of supported options for your computer, go to http://www.ibm.com/pc/; then, select your country and navigate to the list of options for your computer.

Installation guidelines

Before you begin installing options in your computer, read the following information:

v Read the safety information beginning on page 125 and the guidelines in

“Handling electrostatic discharge-sensitive devices” on page 128.. This information will help you work safely with your computer and options.

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

outlets for your computer, monitor, and other devices that you will connect to the computer.

v Back up all important data before you make changes to disk drives. v Have a small flat-blade screwdriver available. v When you need to access the inside of the computer to install options, you might

find it easier to lay the computer on its side.

v Blue on a component indicates touch points, where you can grip the component

to remove it from or install it in the computer, open or close a latch, and so on.

System reliability considerations

To help ensure proper 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 in it.

v There is adequate space around the computer to allow the computer cooling

system to work properly. Leave approximately 50 mm (2 in.) of open space around the front and rear of the computer. Do not place objects in front of the fans. For proper cooling and airflow, replace the computer cover before turning on the computer. Operating the computer for extended periods of time (more than 30 minutes) with the computer cover removed might damage computer components.

v You have followed the cabling instructions that come 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 computer. To

avoid damage, keep static-sensitive devices in their static-protective packages until you are ready to install them.

To reduce the possibility of damage from 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 circuitry. v Do not leave the device where others can handle and damage it.

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

metal part of the computer 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 computer

without setting down the device. If it is necessary to set down the device, put it back into its static-protective package. Do not place the device on your computer cover or on a metal surface.

v Take additional care when handling devices during cold weather. Heating reduces

Power and signal cables for internal drives

Your computer uses cables to connect IDE, Serial ATA, and SCSI devices to the power supply and to the system board. (See “System board internal connectors” on page 72 for the location of system-board connectors.) Review the following information before connecting power and signal cables to internal drives:

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

cables attached. If you replace any drives, remember which cable is attached to which drive, or label the cables.

v When you install a drive, make sure that one of the signal-cable connectors is

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

v The computer has one IDE bus, which is primary. v If you have only one IDE device on a cable, it must be set as a master device.

The following cables are provided:

v Power cables: Four-wire power cables connect the drives to the power supply.

At the end of these cables are plastic connectors that attach to different drives; these connectors vary in size. With Serial ATA drives, you can use either a four-wire power cable or a five-wire Serial ATA power cable, but do not use both at the same time (use one or the other).

v Signal cables: Signal cables typically are flat cables, also called ribbon cables,

that connect IDE, Serial ATA, SCSI, and diskette drives to the system board. Two or three types of signal cables come with your computer:

– IDE: The wider IDE signal 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. The spare connector can be used to connect additional IDE drives to your computer.

Note: The optical drive is attached to an ATA 100 signal cable. ATA 100

signal cables are color-coded. The blue connector is connected to the system board. The black connector is connected to the master IDE device. The gray middle connector is connected to the subordinate IDE device.

– Serial ATA: The narrower, black signal cable has two connectors. One is

connected to the SATA drive, and the other is connected to the connector on the system board. Each SATA drive comes with a cable. If you install an additional SATA drive, you will need an additional cable.

– SCSI: The following cables can be used to attach SCSI devices to the

integrated SCSI controller on the system board:

- An Ultra320 twisted ribbon cable connects the internal Ultra320 SCSI hard disk drive to the SCSI connector on the system board. This cable has four additional connectors for attaching more internal SCSI devices.

- A round SCSI cable connects external SCSI devices to the integrated SCSI controller on the system board. For more information about connecting SCSI devices, see the SCSI documentation.

Installing memory modules

The following notes describe the types of dual inline memory modules (DIMMs) that the computer supports and other information that you must consider when installing DIMMs:

v The computer comes with either two 256 MB or two 512 MB memory DIMMs

installed in DIMM 1 and DIMM 2 memory connectors. The second pair of DIMMs must be installed in DIMM 3 and DIMM 4 memory connectors and the third pair in DIMM 5 and DIMM 6 memory connectors.

v DIMMs must be installed in matched pairs. The DIMMs in each pair must be the

same size, speed, type, and technology as each other but do not have to match the other pairs. You can mix compatible DIMMs from various manufacturers.

v Install only 1.8 V, 184-pin, double-data-rate 2 (DDR2), PC2-3200, registered,

synchronous dynamic random-access memory (SDRAM) with error correcting code (ECC), dual inline memory modules (DIMMs). These DIMMs must be compatible with the latest PC2-3200 SDRAM buffered DIMM specification. For a list of supported options for your computer, go to http://www.ibm.com/pc/; then, select your country and navigate to the list of options for your computer.

v The DIMM-installation sequence is based on single-rank, double-rank, and mixing

single-rank and double-rank memory DIMMs. Single-rank DIMMs are 256 MB, 512 MB, and 1 GB memory modules. Double-rank DIMMs are 2 GB memory modules. The following table lists the DIMM-installation sequence for the computer maximum memory capacity using mixed single-rank and double-rank DIMMs.

Notes:

1. Do not install four, 2 GB double-rank DIMMs for the computer maximum capacity (8 GB) configuration, the computer does not support it.

2. You can install pairs of 256 MB, 512 MB, 1 GB, and 2 GB DIMMs in the computer, but for the computer maximum capacity, you must use the DIMM-sequence in the table below.

3. You can install any combination of DIMM pairs in the computer, however, you can install only two, 2 GB double-rank DIMMs in the computer and they must go in DIMM connectors 1 and 2. Do not install 2 GB double-rank DIMMs in any connectors other than DIMM connectors 1 and 2.

4. If you order memory DIMMs from IBM, the variable 2R in the description indicates that the DIMM is a double-rank 2 GB DIMM.

Table 2. Maximum memory capacity (8 GB) and installation sequence mixing single-rank and double-rank DIMMs

DIMM pair DIMM connectors DIMM size Rank

First pair 1, 2 2 GB Double-rank Second pair 3, 4 1 GB Single-rank Third pair 5, 6 1 GB Single-rank

v The system board contains six DIMM connectors and supports two-way memory

interleaving when the DIMMs are installed in pairs and functioning properly. If one DIMM in the pair fails, the computer runs in single-channel mode (non-interleaving). A failed DIMM must be replaced as soon as possible; otherwise, the computer will not start (boot).

v The DIMM options that are available for the computer are 256 MB, 512 MB, 1

GB, and 2 GB memory modules. The computer supports a minimum of 512 MB and a maximum of 8 MB (when using 2 GB double-rank DIMMs) of system memory.

Chapter 4. Installing options 41

Important: Although the computer supports a maximum of 8 GB of system

memory, the Microsoft Windows operating systems recognize and support a maximum of 4 GB of system memory.

v The memory controller in the computer provides Chipkill memory protection if the

DIMMs are 1 GB or larger, or if the computer is populated with 512 MB x4 DIMMs. Chipkill memory protection is a technology that protects the computer from a single chip failure on a DIMM.

v The amount of usable memory is reduced depending on the system

configuration. A certain amount of memory must be reserved for system resources. The BIOS displays the total amount of installed memory and the amount of configured memory.

Complete the following steps to install DIMMs:

1. Read the safety information beginning on page 125 and “Handling static-sensitive devices” on page 23

2. Turn off the computer and all attached devices (see “Turning off the computer” on page 9); then, disconnect all power cords and external cables.

3. Remove the side cover (see “Removing the side cover” on page 25).

4. Locate the DIMM connectors on the system board. Determine the connectors into which you will install the DIMMs. See Table 2 on page 41 for additional information on DIMM-installation sequences.

Installing a second microprocessor

Your computer comes with one microprocessor installed on the system board. Your computer supports up to two microprocessors. With two microprocessors, your computer can operate as a symmetric multiprocessing (SMP) computer. With SMP, certain operating systems and application programs can distribute the processing load among the microprocessors.

Note: When installing microprocessor options, lay the computer on its side.

The following notes describe information that you must consider when installing an additional microprocessor in your computer:

v Read the documentation that comes with the microprocessor to determine

whether you need to update the computer basic input/output system (BIOS) code. The most current level of BIOS code for the computer is available from http://www.ibm.com/pc/support/.

v (Optional) Obtain an SMP-capable operating system. For a list of supported

operating systems, go to http://www.ibm.com/pc/us/compat/.

v To ensure proper computer operation, use microprocessors that have the same

cache size and type, and the same clock speed. Microprocessor internal and external clock frequencies must be identical. You can use the Configuration/Setup Utility program in your computer to determine the specific type of microprocessor on your system board.

Important: The first microprocessor must always be installed in the

Microprocessor 1 socket.

v The microprocessor speeds are automatically set for this computer; therefore,

you do not need to set any microprocessor frequency-selection jumpers or switches.

v Terminator cards are not required for empty microprocessor sockets. However,

for airflow, an empty microprocessor socket must contain a microprocessor baffle.

v If you need to replace a microprocessor, see “Microprocessor and heat sink” on

page 60.

v For additional illustrations of the system-board components, see “System board

option connectors” on page 71.

v To order additional microprocessor options, contact your IBM marketing

representative or authorized reseller.
