Configuration programs and capabilities

The following configuration programs and capabilities come with the computer:

v Configuration/Setup Utility program

The Configuration/Setup Utility program is part of the basic input/output system

(BIOS) code in your computer. You can use this program to configure serial port

assignments, change interrupt request (IRQ) settings, change the device startup

sequence, set the date and time, set passwords, and set the chassis-intrusion

detector.

v Boot Menu program

Boot Menu program is part of the BIOS code in your computer. Use it to

temporarily assign a device to be first in the startup sequence, overriding the

startup sequence that is set in the Configuration/Setup Utility program.

v Broadcom NetXtreme Gigabit Ethernet Boot Agent

The Broadcom NetXtreme Gigabit Ethernet Boot Agent is part of the BIOS code

in your computer. You can use it to configure the network as a startable device,

and you can customize where the network startup option appears in your startup

sequence. Yo u enable and disable the Broadcom NetXtreme Gigabit Ethernet

Boot Agent from the Configuration/Setup Utility program.

v Ethernet controller configuration

The Ethernet controller is integrated on the system board. Yo u do not need to set

any jumpers or configure the controller. However, you must install a device driver

to enable the operating system to address the controller. For device drivers and

information about configuring your Gigabit Ethernet controller, go to

http://www.ibm.com/pc/support/.

v SCSISelect Utility program (some models)

If your computer comes with a SCSI adapter, you can use the SCSISelect Utility

program to configure devices that are attached to the SCSI adapter. Use this

program to change default values, resolve configuration conflicts, and perform a

low-level format on a SCSI hard disk drive.

Starting the Configuration/Setup Utility program

Complete the following steps to start the Configuration/Setup Utility program:

1. Turn on the computer and watch the monitor screen. If your computer is already on when you start this procedure, you must shut down the operating system, turn off the computer, wait a few seconds until all in-use LEDs go off, and restart the computer.

Chapter 3. Diagnostics

This section provides basic troubleshooting information to help you solve some problems that might occur.

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 115. v The system diagnostic programs are stored on a hidden partition on the

computer hard disk. These programs are the primary method of testing the major components of the computer: the system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), serial ports, hard disk drives, and parallel port. Yo u can also use them to test some external devices. If you are not sure whether a problem is caused by the hardware or by the software, you can use 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 computers 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 computer might be part of a cluster if any of the following conditions is true:

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

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

– One or more computers are located near the failing computer.

v Important:

1. For computers 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 computer is suspended and a POST error code is displayed, see “POST error codes” on page 95.

4. If the computer is suspended and no error message is displayed, see “Error symptoms” on page 87 and “Undetermined problems” on page 102.

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

25.

6. For intermittent problems, check the error log; see “Diagnostic programs and error messages” on page 12.

Complete the following steps to perform the checkout procedure:

001 IS THE COMPUTER PART OF A CLUSTER?

YES. Schedule maintenance for the computer. Shut down all computers

related to the cluster. Run the storage test.

NO. Go to step 002.

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

1. Check the system board LEDs (see “System board error LEDs” on page

79).

2. Turn off the computer and all external devices.

3. Check all cables and power cords.

4. Set all display controls to the middle position.

5. Turn on all external devices.

6. Turn on the computer.

7. Watch the screen for POST errors, and record any POST error messages that are displayed on the screen. If an error is displayed, look up the first error (see “POST error codes” on page 95).

8. Run the diagnostic programs (see “Starting the diagnostic programs and viewing the test log” on page 13).

003 DID THE DIAGNOSTIC PROGRAMS START ?

NO. Find the failure symptom in “Error symptoms” on page 87. YES. Run the diagnostic programs (see “Starting the diagnostic programs

and viewing the test log” on page 13). If you receive an error, see Chapter 6, “Symptom-to-FRU index,” on page

83.

If the diagnostics were completed successfully and you still suspect a problem, see “Undetermined problems” on page 102.

If the computer does not turn on, see “Error symptoms” on page 87.

Diagnostic tools overview

The following tools are available to help you diagnose and solve hardware-related problems:

v POST beep codes and error messages

The power-on self-test generates beep codes and messages to indicate successful test completion or the detection of a problem. See “POST error log” on page 11 for more information.

v Diagnostic programs

The system diagnostic programs are on a hidden partition on the hard disk. These programs are the primary methods of testing the major components of the computer. See “Diagnostic programs and error messages” on page 12 for more information.

v Error charts

These charts list problem symptoms and steps to correct the problem. See “Error symptoms” on page 15 for more information.

v System-board error LEDs

An LED on the system board might also be lit to help isolate an error that is indicated by the system error LED on the front of the computer. See the “System board error LEDs” on page 79 for more information.

10 IntelliStation M Pro Types 6225 and 6228: Hardware Maintenance Manual and Troubleshooting Guide

POST error log

When you turn on the computer, the power on self-test (POST) performs a series of tests to check the operation of system components and some of the installed options.

If POST finishes without detecting any problems, the first window of the operating system opens or an application program starts.

If POST detects a problem, more than one beep or no beep might sound, and an error message appears on the screen.

The POST error log contains the three most recent error codes and messages that the system generated during POST.

Notes:

1. If you have a user password set, you must type the password and press Enter, when prompted, before the operating system will start.

2. A single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After you correct the cause of the first error message, the other error messages usually will be resolved the next time you run the test.

POST beep codes

POST generates beep codes to indicate successful completion or the detection of a problem.

v One short beep indicates the successful completion of POST. v More than one beep or no beep indicates that POST detected a problem. For

more information, see “Beep symptoms” on page 83.

If POST detects a problem (more than one beep sounds), an error message appears on the screen. See “Beep symptoms” on page 83 and “POST error codes” on page 95 for more information.

Small computer system interface (SCSI) messages (some models)

If the computer has an Ultra320 SCSI adapter installed and you receive a SCSI error message, see “SCSI error codes” on page 98.

Note: If the computer does not have a SCSI hard disk drive, ignore any message

that indicates that the BIOS code is not installed.

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.

Note: To help isolate whether a power problem is in the power distribution bus or in

the power supply, check the power supply error LED on the rear of the computer. If this amber LED is lit, replace the power supply.

A general procedure for troubleshooting power problems is as follows:

1. Turn off the computer, 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.

Chapter 3. Diagnostics 25

3. Remove adapters and disconnect the cables and power connectors to all internal and external devices until the computer is at the minimum configuration required to start the computer (see “Undetermined problems” on page 102).

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

To use this method, you must know the minimum configuration required for the computer to start (see page “Undetermined problems” on page 102).

Troubleshooting the Ethernet controller

This section provides troubleshooting information for problems that might occur with the 1 Gbps Ethernet controller.

See the Ethernet controller documentation on the Device Drivers CD for information about problems that might occur with the 1 Gbps Ethernet controller.

The way the Ethernet controller is tested depends on which operating system you are using (see the Ethernet controller device-driver file).

You can use the Ethernet wrap test to determine whether a hardware problem is causing the Ethernet connection to fail. To perform the Ethernet wrap test, use the wrap plug (IBM part number 60G3981) with the diagnostic tests.

If this testing method indicates that the hardware is functioning normally but the problem remains, see “Network connection problems” or inform the network administrator.

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 rear of the computer.

The Ethernet link status LED, on the rear of the computer, 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

the computer.

v Check for operating-system-specific causes for the problem. v Make sure that the device drivers on the client and computer are using the same

protocol.

Ethernet controller troubleshooting chart

Use the following troubleshooting chart to find solutions to 10/100/1000 Mbps Ethernet controller problems that have definite symptoms.

Ethernet controller problem

The computer stopped running when loading device drivers.

Ethernet link status LED does not work.

Data is incorrect or sporadic.

The Ethernet controller stopped working when another adapter was added to the computer.

The Ethernet controller stopped working without apparent cause.

FRU/actions

The PCI BIOS interrupt settings are incorrect.

v Determine whether the interrupt (IRQ) setting assigned to the Ethernet controller is also

assigned to another device in the Configuration/Setup Utility program. Although interrupt sharing is allowed for PCI devices, some devices do not function well

when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet controller or the other device. For example, for NetWare Versions 3 and 4, it is recommended that disk controllers not share interrupts with LAN controllers.

v Make sure that you are using the most recent device driver available from the World

Wide Web.

v Reseat or replace the adapter. v Make sure that the hub is turned on.

v Check all connections at the Ethernet controller and the hub. v Use another port on the hub. v If the hub does not support auto-negotiation, manually configure the Ethernet controller

to match the hub.

v If you manually configured the duplex mode, make sure that you also manually configure

the speed.

v Reseat or replace the adapter. v Make sure that you are using Category 5 or higher cabling when operating the computer

at 100 Mbps or at 1000 Mbps.

v Make sure that the cables do not run close to noise-inducing sources such as

fluorescent lights.

v Make sure that the cable is connected to the Ethernet controller. v Make sure that the PCI system BIOS code is current. v Reseat the adapter. v Determine whether the interrupt (IRQ) setting assigned to the Ethernet adapter is also

assigned to another device in the computer. Use the Configuration/Setup Utility program to determine if this is the case.

Although interrupt sharing is allowed for PCI devices, some devices do not function well when they share an interrupt with a dissimilar PCI device. Try changing the IRQ assigned to the Ethernet adapter or the other device.

v Reseat or replace the adapter. v Try a different connector on the hub.

v Reinstall the device drivers. See the operating-system documentation. v Reseat or replace the adapter.

Chapter 4. Customer replacement units

This chapter provides basic instructions for installing hardware options in the computer. These instructions are intended for users who are experienced with setting up IBM computer hardware.

Installation guidelines

Before you begin installing options, read the following information:

v Read Appendix B, “Safety information,” on page 115, and the guidelines in

“Handling static-sensitive devices.” This information will help you work safely with the computer and options.

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

outlets for the computer, monitor, and other devices.

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 The blue color on components and labels identifies touch points, where you can

grip a component, move a latch, and so on.

System reliability guidelines

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 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 the computer and other electronic

devices. 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 the computer cover or on a metal surface.

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

indoor humidity and increases static electricity.

Power and signal cables for internal drives

Your computer uses cables to connect IDE, SATA, and SCSI devices to the power supply and to the system board. (See “System board internal connectors” on page 78 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.

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

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

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 computer might not recognize some of the IDE devices. The primary and secondary designation is determined by switch or jumper settings on each IDE 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 can be attached to different drives; these connectors vary in size. Yo u can use either a four-wire power cable or serial ATA power cable with serial ATA drives, but do not use both at the same time (use one or the other).

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

that connect parallel IDE, SATA, SCSI, and diskette drives to the system board. Two or three types of signal cable 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 IDE connector on the system board.

The CD-ROM drive is attached to an ATA 100 signal cable. ATA 100 signal cables are color-coded. The blue connector is attached to the system board. The black connector is attached to the primary IDE device. The gray middle connector is attached to the secondary IDE device.

– Diskette drive (optional): The narrower signal cable has two connectors.

One is attached to the diskette drive, and the other is attached to the diskette drive connector on the system board.

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

attached to the SATA drive, and the other is attached 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. SATA signal cables should be connected to the system board connectors (SATA 1 through SATA 4) in numerical order, starting with SATA 1.

– SCSI: The Ultra320 twisted ribbon cable connects the internal Ultra320 SCSI

hard disk drive to the mini-PCI SCSI connector. This cable has three additional connectors for attaching more internal SCSI devices.

Chapter 4. Customer replacement units 53

Installing memory modules

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

v When you restart the computer after adding or removing a DIMM, the computer

displays a message that the memory configuration has changed.

v Your computer uses industry-standard PC2-3200 double-data-rate 2 (DDR2)

DIMMs.

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

interleaving.

v The DIMM options available for your computer are 256 MB, 512 MB, and 1 GB,

which come in matched pairs. Your computer supports a minimum of 512 MB and a maximum of 4 GB of system memory.

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

that are installed in DIMM 1 and DIMM 3 memory connectors. The second pair of DIMMs must be installed in DIMM 2 and DIMM 4 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. Yo u can mix compatible DIMMs from various manufacturers.

v Install only 1.8 V, 240-pin, DDR2, PC2-3200, unbuffered synchronous dynamic

random-access memory (SDRAM) with error correcting code (ECC) DIMMs. These DIMMs must be compatible with the latest PC2-3200 SDRAM unbuffered 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 amount of usable memory will be reduced depending on the system

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

Complete the following steps to install a DIMM:

1. Read Appendix B, “Safety information,” on page 115 and the guidelines in “Handling static-sensitive devices” on page 29.

2. Turn off the computer and all attached devices (see “Turning off the computer” on page 6); then, disconnect all external cables and power cords.

3. Remove the side cover (see “Removing the side cover” on page 32).

4. For easier access to the memory modules, rotate the drive cage out of the computer. Grasp the drive cage and rotate it until it locks into place.

5. Locate the DIMM connectors on the system board. Determine the connectors into which you will install the DIMMs. Remember that DIMM 1 and DIMM 3 must be paired together (and must be the first installed pair) and DIMM 2 and DIMM 4 must be paired together. The following table shows the installation sequence.

Memory installation sequence DIMMs Slots

2 DIMMs 1, 3 4 DIMMs 1, 3, 2, 4
