About This Book

The IBM PS/ValuePoint (PS/VP) Hardware Maintenance Manual contains IBM PS/ValuePoint computers.

 The service section of this manual includes

procedures for isolating problems to a FRU, a Symptom-to-FRU Index, and a parts listing.

 The reference section of this manual includes safety

information, general information, product description, and information about the diagnostic tests.

The manual should be used with the diagnostic tests (found on the Diagnostics diskette) to effectively troubleshoot problems.

Important

 This manual is intended for trained servicers who

are familiar with PS/ValuePoint products.

 Before servicing a PS/ValuePoint product, review

“Safety Information” on page 28.

 Refer to the following table to use the correct

“Advanced Diagnostics” diskette for the computer you are servicing.

Diskette Type PS/ValuePoint Model

Hardware Maintenance Service

This section contains a general checkout and diagnostic test procedure, a Symptom-to-FRU Index, procedures for isolating problems to a FRU, and a parts catalog for IBM PS/ValuePoint* (PS/VP) computers.

The diagnostic tests in this manual are intended to test

only

PS/ValuePoint products. Non-PS/ValuePoint products, prototype cards, or modified options can give false errors and invalid computer responses.

Warning: The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive.

How to Diagnose Combined FRUs: If an

adapter or device consists of more than one FRU, an error code might be caused by any of the FRUs. Before replacing the adapter or device, remove the FRUs, one by one, to see if the symptoms change.

Notes:

1. If you are instructed to replace the system board and that does not correct the problem, replace the riser card and reinstall the original system board.

2. If you are instructed to replace any other FRU and that does not correct the problem, reinstall that FRU before you continue.

How to Use Error Messages: Use the error

messages displayed on the screen to diagnose failures. If more than one error message is displayed, diagnose the first error message. The cause of the first error message can cause false error messages to be displayed. If you did not receive any error messages, see if the error symptom is listed in the “Symptom-to-FRU Index” on page 12.

The general checkout procedure starts on the next page.

1. Power-off the computer and display.

2. Disconnect the display signal cable.

3. Power-on the display.

4. Turn the brightness and contrast controls clockwise to their maximum setting.

5. Check for the following conditions:

 You should be able to vary the screen intensity

by adjusting the contrast and brightness controls.

 The screen should be white or light gray, with a

black margin (test margin) on the screen. Note: The location of the test margin varies

with the type of display. The test margin might be on the top, bottom, or one or both sides.

If you do not see any test margin on the screen, replace the display. If there is a test margin on the screen, replace the system board.

Note: During the first two or three seconds after the

display is powered on, the following might occur while the display synchronizes with the computer.

 Unusual patterns or characters  Static, crackling, or clicking sounds  A “power-on hum” on larger displays

A noticeable odor might occur on new displays or displays recently removed from storage.

These sounds, display patterns, and odors are normal; do not replace any parts.

If you are unable to correct the problem, go to “Undetermined Problem” on page 5.

Hardware Maintenance Service

Installed Devices List

Warning: A customized setup configuration (other than

default settings) might exist on the computer you are servicing. Running the Configuration Utility program might alter those settings. Note the current configuration settings and verify that the settings are in place when service is complete.

If the number of diskette drives shown in the installed devices list is not correct

1. Restart the computer.

2. Run the Configuration Utility program to correct the drive information.

3. Run the diagnostic tests.

If you cannot correct the drive information, replace FRUs, in the following order, until the problem goes away:  Diskette drive  Diskette-drive cable  System board

If the number of hard disk drives shown in the installed devices list is not correct

1. Check the hard disk drive jumper settings (see “Hard Disk Drive Jumper Settings” on page 68).

2. Check the voltages to the hard disk drives (see “Power Supply” on page 6).

3. Restart the computer and check the configuration.

 If the first drive is missing, replace the primary

drive.

 If all drives are missing, replace the primary

drive.

 If just the second drive is missing, replace that

drive. If the problem remains, replace the drive cable. If that does not fix the problem, replace the system board.

If any other adapter or device is missing from the installed devices list, run the Configuration Utility program. Check to see if any adapter or device is set to a conflicting address with any other adapter or device. Also be sure that any adapter or device missing from the list is not set to “disabled”

Note: If you cannot add a missing adapter or device to

the list, the diagnostic code for the missing adapter or device is not on the diagnostic diskette. Run the diagnostics provided with that device.

, do the following:

When the problem goes away, replace the last kit removed. If that does not fix the problem, replace the system board.

Hardware Maintenance Service 11

Symptom-to-FRU Index

The Symptom-to-FRU Index lists error symptoms and possible causes. The most likely cause is listed first. Always begin with “General Checkout” on page 2. This index can also be used to help you decide which FRUs to have available when servicing a computer. If you are unable to correct the problem using this index, go to “Undetermined Problem” on page 5.

Notes:

1. If you have both an error message and an incorrect audio response, diagnose the error message first.

2. If you cannot run the diagnostic tests, but did receive a POST error message, diagnose the POST error message.

3. If you did not receive any error message, look for a description of your error symptoms in the first part of this index.

4. Check all power supply voltages before you replace the system board. (See “Power Supply” on page 6.)

5. Check the hard disk drive jumper settings before you replace a hard disk drive. (See “Hard Disk Drive Jumper Settings Checkout” on page 51.)

Important

 For the 6381, some errors are indicated with a

series of beep codes (see “Model 6381 Beep Code Index” on page 17).

 The 6384 P60/D uses the same POST error

codes as other PS/ValuePoint computers; however, it uses unique diagnostic numeric error codes. In the following Symptom-to-FRU Index, all 6384 P60/D diagnostic numeric error codes include the message “(6384 P60/D only).”

 For the 6384 /D, if a SoundBlaster card is

installed, beeps operate through the SoundBlaster card. If a “No Beep” error occurs, remove the SoundBlaster card and power-on the computer. If normal beeps occur, replace the SoundBlaster card.

Safety Information

The following section contains the safety information required to service a PS/ValuePoint computer. Familiarize yourself with this information before servicing a PS/ValuePoint computer.

General Safety

Use these rules to ensure general safety:

 Observe good housekeeping in the area of the

machines during maintenance and after completing it.

 When lifting any heavy object:

1. Ensure you can stand safely without slipping.

2. Distribute the weight of the object equally between your feet.

3. Use a slow lifting force. Never move suddenly or twist when you attempt to lift.

4. Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back.

objects that weigh more than 16 kg (35 lb) or objects that you think are too heavy for you.

 Do not perform any action that causes hazards to the

customer or that makes the equipment unsafe.

 Before you start the machine, ensure that other

service representatives and the customer's personnel are not in a hazardous position.

 Put removed covers and other parts in a safe place,

away from all personnel, while you are servicing the machine.

 Keep your tool case away from walk areas so that

other people will not trip over it; for example, put it under a desk or table.

 Do not wear loose clothing that can be trapped in the

moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.

 Insert the ends of your necktie or scarf inside other

clothing or fasten the necktie with a clip, preferably nonconductive, approximately 8 cm (3 in.) from the end.

 Do not wear jewelry, chains, metal-frame eyeglasses,

or metal fasteners for your clothing. Remember: Metal objects are excellent conductors.

 Wear safety glasses when you are:

– Using a hammer to drive pins or similar parts – Drilling with a power hand-drill – Using spring hooks or attaching springs

– Soldering parts

– Cutting wire or removing steel bands – Cleaning parts with solvents, chemicals, or

cleaning fluids

Do not attempt to lift any

28 PS/ValuePoint HMM

– Working in any other conditions that might be

hazardous to your eyes.

 After maintenance, reinstall all safety devices such as

shields, guards, labels, and ground wires. Exchange any safety device that is worn or defective for a new one.

Remember: Safety devices protect personnel from hazards. You destroy the purpose of the devices if you do not reinstall them before completing your service call.

 Reinstall all covers correctly before returning the

machine to the customer.

Safety Inspection Guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

 Electrical hazards, especially primary power: primary

voltage on the frame can cause serious or fatal electrical shock.

 Explosive hazards, such as a damaged CRT face or

bulging capacitor, can cause serious injury.

 Mechanical hazards, such as loose or missing

hardware, can cause serious injury.

The guide consists of a series of steps presented in a checklist. Begin the checks with the power-off and the power cord removed from the power receptacle.

Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).

2. Power-off the computer. Disconnect the power cord from the electrical outlet.

3. Check the power cord for:

a. A third-wire ground connector in good condition.

Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.

b. Insulation must not be frayed or worn.

4. Remove the cover.

Hardware Maintenance Reference

5. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

6. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

7. Check for worn, frayed, or pinched cables.

8. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Changing the Battery

Follow any special handling and installation instructions supplied with the replacement battery.

CAUTION: A danger of explosion exists if battery is incorrectly replaced.

Replace with only the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

Handling Electrostatic Discharge (ESD) Sensitive Devices

Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the machine, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.

2. Make sure that the ESD protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

 Keep the parts in protective packages until they are

inserted into the product.

 Avoid contact with other people.  Wear a grounded wrist strap against your skin to

eliminate static on your body.

 Prevent the part from touching your clothing. Most

clothing is insulative and retains a charge even when you are wearing a wrist strap.

 Use the black side of a grounded work mat to provide

a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.

 Select a grounding system, such as those listed

below, to provide protection that meets the specific service requirement.

30 PS/ValuePoint HMM

Note: The use of a grounding system is desirable

but not required to protect against ESD damage.

– Attach the ESD ground clip to any frame ground,

ground braid, or green-wire ground.

– Use an ESD common ground or reference point

when working on a double-insulated or battery-operated computer. You can use coax or connector-outside shells on these computers.

– Use the round ground-prong of the AC plug on

AC-operated computer.

Electrical Safety

Observe the following rules when working on electrical equipment:

 Find the room emergency power-off (EPO) switch or

disconnecting switch. If an electrical accident occurs, you can then operate the switch quickly.

 Do not work alone under hazardous conditions or

near equipment that has hazardous voltages.

 Disconnect all power:

– Before doing a mechanical inspection – Before working near power supplies – Before removing or installing main units

 Before you start to work on the machine, unplug its

power cable. If you cannot unplug the cable, ask the customer to switch off the wall box that supplies power to the machine and to lock the wall box in the off position.

 If you need to work on a machine that has

electrical circuits, observe the following precautions:

– Ensure that another person, familiar with the

power-off controls, is near you. Remember: Another person must be there to

switch off the power, if necessary.

CAUTION: Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents. Use only approved tools and testers.

– Use only one hand when working with powered

on electrical equipment; keep the other hand in your pocket or behind your back.

Remember: There must be a complete circuit to cause electrical shock. By observing the above rule, you might prevent a current from passing through your body.

– When using testers, set the controls correctly

and use the approved probe leads and accessories for that tester.

exposed

Hardware Maintenance Reference

CAUTION: Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

– Stand on suitable rubber mats (obtained locally,

if necessary) to insulate you from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

 Regularly inspect and maintain your electrical hand

tools for safe operational condition.

 Do not use worn or broken tools and testers. 

Never assume

from a circuit. First,

that power has been disconnected

check

that it has been switched

off.

 Always look carefully for possible hazards in your

work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.

 Do not touch live electrical circuits with the reflective

surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage.

 Do not service the following parts

with the power on

when they are removed from their normal operating places in a machine:

– Power supply units

– Pumps

– Blowers and fans

– Motor generators and similar units. (This practice ensures correct

grounding of the units.)

 If an electrical accident occurs:

– Use caution; do not become a victim

yourself. – Switch off power. – Send another person to get medical aid.

Configuration Utility Program

The Configuration Utility program lets you view and change important hardware configuration information. Use the Configuration Utility program to:

 Restore a customized configuration when service is

complete.

 Check the computer configuration when you get an

error code and description.

 Check the computer hardware features, such as the

amount of memory.

 Verify or make a change when you add a

option

, such as a diskette drive, memory module, or

math coprocessor.

 Verify a hardware change when you remove a

hardware option.

 Change the computer serial and parallel port settings.  Set up or change the computer password protection.

Diskette Drive (A: or B:)

This option displays an entry for each diskette drive in the computer. If you add or change a diskette drive, you must select the correct diskette drive type on the Configuration Utility screen.

Power-On Password

A password must be entered each time the computer is powered on.

Startup Sequence

When the computer starts, it looks for operating system files on a diskette and then on the hard disk. If there is a diskette in the diskette drive that does not contain the operating system files, most computers send an error message and stop operating.

The PS/ValuePoint computer, however, has a

smart

startup sequence that automatically looks for operating system files on the hard disk if the files are not found on a diskette.

Note: On some models, selectable boot can be selected

directly from the configuration utility screen.

Serial Port

The computer has either one or two serial ports. Each serial port has a special

address

(identifying location) assigned to it. If you add adapter cards to the computer that have additional serial ports, you must ensure that each serial port has a different address.

The Serial Port option lets you change the serial port addresses. If you change serial port addresses on the Configuration Utility screen, you also might need to make changes to the software. For instructions on changing the software, see the user’s guide or online information that came with the software.

Parallel Port

The computer has one parallel port with a special

address

(identifying location) assigned to it. If you add adapter cards to the computer that have additional parallel ports, you must ensure that each parallel port has a different address.

The Parallel Port option lets you change the parallel port addresses. If you change parallel port addresses on the Configuration Utility screen, you also might need to make changes to the software. For instructions on changing the software, see the user’s guide or online information that came with the software.

Date and Time You can change the date and time on the computer using the Date and Time options. The changes take effect immediately.

Type the date in the format displayed on the screen. Type the time in 24-hour format. For example:

12 midnight is ðð:ðð 12 noon is 12:ðð

1 p.m. is 13:ðð

Diagnostics and Test Information (6381, 6382, 6384, 6387)

The following information is helpful when diagnosing computer problems on types 6381, 6382, 6384, and 6387. For Model 6384 P60/D, see “Diagnostics and Test Information (6384 P60/D)” on page 61.

Power-On Self Test

Each time you power-on the computer, the power-on self test (POST) is initiated. The POST takes up to 90 seconds to complete, depending on the options installed.

The POST checks the following:  System board

 Memory  Video

 Hard disk drive(s)  Diskette drive(s)  Keyboard  Mouse  Parallel port  Serial port(s)

To start the POST, power-on the display and the computer. The following happens:

1. The following icon

appears at the upper-right corner of the display. Pressing F1 at this time causes the Configuration Utility menu to appear after the POST has completed.

2. A count of the computer memory appears at the upper-left corner of the display.

3. If an error is detected, an error code appears under the computer memory count.

Note: Memory errors appear as XXXXXX XXXX 201

in the upper-left corner of the display (X can be a number or letter).

4. Successful completion of POST is attained when there are no errors detected in the computer.

5. The computer attempts to load the operating system. If an operating system is not found, a graphic message (icon) is displayed requesting the user to insert a diskette into drive A and press the F1 key to resume operation.

6. If a critical error is encountered, the POST is halted.

Hardware Maintenance Reference

Formatting a Hard Disk Drive: Hard disk drives

normally contain tracks in excess of their stated capacity to allow for defective tracks. The user is notified by a diagnostic message when the defect limit has been reached and service is recommended.

The Diagnostics Format program is different from the operating system format program. Before the customer can transfer information from the backup diskettes to the hard disk drive, the hard disk drive must be formatted using the operating system format program. Have the customer refer to the operating system manual for a description of the hard disk preparation commands.

Note: The Diagnostics Format program on this diskette

might damage non-IBM hard disk drives. Refer to the documentation that came with the drive for low-level formatting information.

Warning: All data on the selected hard disk drive is destroyed during a format operation or surface analysis.

9 - RETURN TO HARD DISK MENU: Returns to the Hard Disk Diagnostic menu.

56 PS/ValuePoint HMM

Warning: Formatting results in a complete loss of data on the hard disk drive, including system programs. If you are directed to or elect to format the hard disk drive, you must do the following:

1. Prior to formatting, have the customer back up all information, if possible.

2. Prior to returning the computer to the customer, you must reinstall the system programs on the hard disk.

Formatting Procedure: Before replacing a failing

hard disk drive, try to format it as follows:

1. Power-off the computer. Check that the hard disk drive cable is tightly connected.

2. Insert the Diagnostics diskette into drive A.
