Chapter 1. General checkout

This general checkout procedure is for type 6838, 6848 computers.

Attention:

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.

Diagnostic error messages appear when a test program finds a problem with a hardware option. For the test programs to properly determine if a test Passed, Failed or Aborted, the test programs check the error-return code at test completion. See Chapter 3, “Diagnostics”, on page 7.

General error messages appear if a problem or conflict is found by an application program, the operating system, or both. For an explanation of these messages, refer to the information supplied with that software package.

Notes:

v Type 6838, 6848 computers default to come up quiet (no beep and no memory count and checkpoint code

display) when no errors are detected by POST.

v To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:

1. Select Start Options in the Configuration/Setup Utility program (see “Using the Configuration/Setup Utility

program” on page 19).

2. Set Power-On Self-Test to Enhanced.

v Before replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS

might cause false errors and unnecessary replacement of the system board.

v If multiple error codes are displayed, diagnose the first error code displayed. v If the computer hangs and no error is displayed, go to “Undetermined problems” on page 71. v If an installed device is not recognized by the diagnostics program, that device might be defective.

POST

When you turn on the computer, it performs a series of tests to check the operation of system components and some of the options that are installed in the computer. This series of tests is called the power-on self-test or POST.

If POST finishes without detecting any problems, the first window of your operating system or application program appears.

Notes:

1. If you have a power-on password set, you must type the password and press

Enter, when prompted, before POST will continue.

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 not occur the next time you run the test.

POST beep code descriptions

The possible types of beep codes that your system might emit are:

Repeating long beeps

Indicates that a memory error has occurred. Ensure that all RIMMs are correctly installed.

One long beep and two short beeps

Indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. Ensure that the video adapter is correctly installed.

Small computer system interface messages (some models)

The following table lists actions to take if you receive any error message.

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

indicates that the BIOS is not installed.

Page 16

You will get these messages only when running the SCSISelect Utility.

Table 1. SCSI messages

SCSI Messages Description

All One or more of the following might be causing the problem.

v A failing SCSI device (adapter or drive) v An improper SCSI configuration v Duplicate SCSI IDs in the same SCSI chain v An improperly installed SCSI terminator v A defective SCSI terminator v An improperly installed cable v A defective cable

Action: Verify that:

v The external SCSI devices are turned on. External SCSI devices must

be turned on before the computer.

v The cables for all external SCSI devices are connected correctly. v The last device in each SCSI chain is terminated properly. v The SCSI devices are configured correctly.

If the above items are correct, run the diagnostic programs to obtain additional information about the failing device.

IBM Enhanced Diagnostics

The system diagnostic programs are stored on the Device Drivers and IBM Enhanced Diagnostics CD. These programs are the primary method of testing the major

components of your computer.

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 computer 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 running the diagnostic programs.

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 and are described in the Hardware Maintenance Manual.)

8 IBM NetVista Type 6838, 6848: Hardware Maintenance Manual

Page 17

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

and are described in the Hardware Maintenance Manual.)

date is the date that the diagnostic test was run and the error recorded. cc are the check digits that are used to verify the validity of the information. text message

is the diagnostic message that indicates the reason for the problem.

Text messages

The diagnostic text message format is as follows:

Function Name: Result (test specific string)

where:

Function Name

is the name of the function being tested when the error occurred. This corresponds to the function code (fff) given in the previous list.

Result can be one of the following:

Passed

Failed This result occurs when the diagnostic test discovers an error.

This result occurs when the diagnostic test completes without any errors.

User Aborted

This result occurs when you stop the diagnostic test before it is complete.

Not Applicable

This result occurs when you specify a diagnostic test for a device that is not present.

Aborted

This result occurs when the test could not proceed because of the system configuration.

Warning

This result occurs when a possible problem is reported during the diagnostic test, such as when a device that is to be tested is not installed.

Test Specific String

is additional information that is used to analyze the problem.

Starting the diagnostic programs

The IBM Enhanced Diagnostics programs will isolate your computer hardware from software that you have installed on your hard disk drive. The programs run independently of the operating system, and must be run either from a CD or diskette. This method of testing is generally used when other methods are not accessible or have not been successful in isolating a problem suspected to be hardware related.

A Device Drivers and IBM Enhanced Diagnostics CD comes with your computer. You can also download the latest diskette image of the diagnostics from http://www.ibm.com/pc/support on the World Wide Web.

Rambus inline memory modules (RIMMs)

The IBM-installed RIMMs are ECC (error checking and correction) RDRAM (Rambus dynamic random access memory) modules.

Chapter 3. Diagnostics 11

Page 20

When installing or replacing RIMMs, take the following information into consideration:

v RIMM connectors do not support dual inline memory modules (DIMMs) v Use only PC600 or PC800 RIMMs. v RIMMs must be installed in pairs. The RIMMs installed in a RIMM connector

pair must be of the same speed, and size.

v Any connector that does not have a RIMM installed must have a continuity

RIMM (C-RIMM).

v Install only ECC RIMMS to enable ECC. If ECC and non-ECC memory are used

together, the memory will function as non-ECC memory.

Note: If PC600 and PC800 RIMMs are used together, all memory will function at

the speed of the slowest RIMM.

Supported RIMM memory configuration

Types 6838 and 6848 have two memory channels with two memory sockets for each channel, making a total of four RIMM memory sockets. RIMM sockets must have a RIMM memory module or a C-RIMM (RIMM Continuity module) installed. There can be no empty RIMM sockets. RIMM sockets must contain either a RIMM or a C-RIMM. At least one socket from each memory channel must have a RIMM memory module installed.

Note: Both memory channels must be populated the same.

v RIMM sockets 1 and 3 are on memory channel A. v RIMM sockets 2 and 4 are on memory channel B.

Each RIMM socket supports a maximum of 512 MB of memory.

v If new memory is to be added in a memory channel, remove a C-RIMM and

install the new RIMM. (You must also do the same with the other memory Channel).

v If memory is to be removed from a memory channel, remove the RIMM and

install a C-RIMM. (You must also do the same with the other memory Channel).

12 IBM NetVista Type 6838, 6848: Hardware Maintenance Manual

Page 21

RIMM sizes of 64 MB, 128 MB, 256 MB, and 512 MB are acceptable. RIMM sockets, within each memory channel, can be filled in any order. However, both memory channels must be populated the same. ECC or non-ECC, RAMBUS dynamic random access memory (RDRAM) are supported. If ECC and non-ECC are installed together, all memory will function as non-ECC.

Note: Mixed RIMM speeds will run at the lower speed.

RIMM diagnostic approach

Identify any Beep or POST codes. See Chapter 7, “Symptom-to-FRU index”, on page 47.

Use the IBM PC Enhanced Diagnostics program to run memory tests. See “IBM Enhanced Diagnostics” on page 8.

Procedures to determine memory errors

Installing memory modules

Adding memory to your computer is an easy way to make programs run faster. You can increase the amount of memory in your computer by installing memory modules. Your NetVista computer uses industry-standard, RAMBUS in-line memory modules (RIMMs).

Notes:

1. Any connector that does not have a RIMM installed must have a continuity

RIMM (C-RIMM), a module that looks like a RIMM but has no memory on it. A C-RIMM is used to continue the connection on a RIMM connector that does not have memory installed.

2. Install only ECC RIMMs to enable ECC. If you use ECC and non-ECC memory

together, it will function as non-ECC memory.

3. RIMM connectors do not support dual inline memory modules (DIMMs).

4. Use only PC600 or PC800 RIMMs.

Note: If you use PC600 and PC800 RIMMs together, all memory will function

5. Your NetVista Types 6838 and 6848 computers support 128 MB, 256 MB, and

512 MB RIMMs. Your computer supports a minimum of 128 MB and a

at the speed of the slowest RIMM.

Rambus inline memory modules (RIMMs)

The IBM-installed RIMMs are ECC (error checking and correction) RDRAM (Rambus dynamic random access memory) modules.

When installing or replacing RIMMs, take the following information into consideration:

v RIMM connectors do not support dual inline memory modules (DIMMs) v Use only PC600 or PC800 RIMMs. v RIMMs must be installed in pairs. The RIMMs installed in a RIMM connector

pair must be of the same speed, and size.

v Any connector that does not have a RIMM installed must have a continuity

RIMM (C-RIMM).

v Install only ECC RIMMS to enable ECC. If ECC and non-ECC memory are used

together, the memory will function as non-ECC memory.

Note: If PC600 and PC800 RIMMs are used together, all memory will function at

the speed of the slowest RIMM.

Supported RIMM memory configuration

Types 6838 and 6848 have two memory channels with two memory sockets for each channel making a total of four RIMM memory sockets. RIMM sockets must have a RIMM memory module or a C-RIMM (RIMM Continuity module) installed. There can be no empty RIMM sockets. RIMM sockets must contain either a RIMM or a C-RIMM. At least one socket, from each memory channel, must have a RIMM memory module installed.

Note: Both memory channels must be populated the same.

v RIMM sockets 1 and 3 are on memory channel A. v RIMM sockets 2 and 4 are on memory channel B.

Each RIMM socket supports a maximum of 512 MB of memory.

v If new memory is to be added in a memory channel, remove a C-RIMM and

install the new RIMM. (You must also do the same with the other memory Channel).

v If memory is to be removed from a memory channel, remove the RIMM and

install a C-RIMM. (You must also do the same with the other memory Channel).

Note: Mixed RIMM speeds will run at the lower speed.

Procedures to determine memory errors:

1. If a memory error occurs, and the system is operational, run memory

diagnostics.

2. If a memory error occurs, and the system is not operational: a. Replace one RIMM module at a time until the system comes up.

Note: All unused RIMM sockets must have a C-RIMM installed.

b. Run memory diagnostics. c. Install the other RIMM and run diagnostics again to identify the failing

RIMM.

Chapter 6. FRU information (service only) 41

Page 50

RIMM diagnostic approach

Identify any Beep or POST codes. See Chapter 7, “Symptom-to-FRU index”, on page 47.

Use the IBM PC Enhanced Diagnostics program to run memory tests. See “IBM Enhanced Diagnostics” on page 8.

Replacing a system board

Notes:

1. The BIOS and Vital Product Data (VPD) for the computer you are servicing must be

installed on the new system board (FRU) after it is installed in the computer. To do this, you must run the Flash Update program using the Flash Update diskette.See “BIOS levels” on page 73, “Vital product data” on page 72, and “Flash (BIOS/VPD) update procedure” on page 74.

2. Always ensure the latest level of BIOS is installed on the computer. A down level BIOS

may cause false errors and unnecessary replacement of the system board.

3. The processor is a separate FRU from the system board and is not included with the

system board FRU.

4. If the new system board does not correct the problem, reinstall the options on the old

system board, reinstall the old system board, then replace the processor.

To replace the system board, do the following:

1. Remove the 10 screws that attach the system board to the chassis.

42 IBM NetVista Type 6838, 6848: Hardware Maintenance Manual

Page 51

2. Remove the board from the chassis.

3. Remove the processor from the old system board and install it on the new

system board.

4. Remove any of the following installed options on the old system board, and

install them on the new system board. v Memory modules

5. Ensure that the new system board jumper settings match the old system board

jumper settings.

Replacing a processor

Make sure the processor is fully seated in its socket and that the goal post latches are engaged.

Important:

1. Make sure the fansink and air baffle (if any) are installed to prevent processor

overheating.

2. If the processor is not installed correctly, the system board and the processor can be

damaged.

Speaker removal

1. Remove the cover (see “Removing the cover” on page 26).

Chapter 6. FRU information (service only) 43

Page 52

2. The speaker is secured by one tab on either side and two at the bottom. Firmly push the speaker up from the bottom until it comes out from the tabs.

Power supply

If the power-on indicator is not on, the power supply fan is not running, or the computer will not power-off, use the following procedures.

Check/Verify FRU/Action

Check the following for proper installation.

v Power Cord v On/Off Switch connector v On/Off Switch Power Supply connector v System Board Power Supply connectors v Microprocessor(s) connection

Check the power-on switch for continuity. Power Cord Check the power-on switch for continuity. Power-on Switch

POST error codes

Each time you power-on the system, it performs a series of tests that check the operation of the system and some options. This series of tests is called the Power-On Self-Test,orPOST. POST does the following operations.

v Checks some basic system-board operations v Checks the memory operation

66 IBM NetVista Type 6838, 6848: Hardware Maintenance Manual

Page 75

v Starts the video operation v Verifies that the diskette drive is working v Verifies that the hard disk drive is working

If the POST finishes without detecting any problems, a single beep sounds and the first screen of the operating system or application program appears.

Note:

Type 6838, 6848 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected by POST.

To enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:

1. Select Start Options in the Configuration/Setup Utility program (see “Using the

2. Set Power-On Self-Test to Enhanced.

If the POST detects a problem, an error message appears on the screen. A single problem can cause several error messages to appear. When you correct the cause of the first error message, the other error messages probably will not appear on the screen the next time you turn on the system.

During the POST, the BIOS generates diagnostic progress codes (POST codes) to I/O port 80h. If the POST fails, execution stops and the last POST code generated is left at port 80h. This code is useful for determining the point where an error occurred.

Displaying the POST codes requires an add-in card, often called a POST card (PCI, not ISA). The POST card can decode the port and display the contents on a medium such as a seven-segment display.

The tables below offer descriptions of the POST codes generated by the BIOS.

Security features

Security features in this section include the following:

v Passwords v Vital Product Data v Management Information Format (MIF) v Alert on LAN

Passwords

The following section provides information about computer hardware and software-related passwords.

v Power-on Password v Administrator Password v Operating System Password

Chapter 7. Symptom-to-FRU index 71

Page 80

Power-on and Administrator passwords are set in the Setup Utility program. See “Using the Configuration/Setup Utility program” on page 19 for information about running the Setup Utility.

Power-on password

A power-on password denies access to the computer by an unauthorized user when the computer is powered on. When a power-on password is active, the password prompt appears on the screen each time the computer is powered on. The computer starts after the proper password is entered.

Removing a power-on password

To service a computer with an active and unknown power-on password, power-off the computer and use the following procedure.

Note: On some models, this procedure will also remove the administrator password.

1. Unplug the power cord and remove the top cover.

2. Refer to “System board layout” on page 39 to find the recovery jumper.

3. Move the recovery jumper from normal to clear.

4. Power-on the computer. The system senses the change in the position and

erases the password. It is necessary to move the jumper back to the previous position.

5. Remind the user to enter a new password when service is complete.

Administrator password

The administrator password is used to restrict access to the Configuration/Setup Utility program. If the administrator password is activated, and you do not enter the administrator password, the configuration can be viewed but not changed.

Note:

Type 6838, 6848 computers have Enhanced Security Mode. If Enhanced Security mode is enabled and there is no password given, the computer will act as if Enhanced Security is disabled.

If Enhanced Security is Enabled and an administrator password is given, the administrator password must be entered to use the computer. If the administrator password is lost or forgotten, the system board in the computer must be replaced in order to regain access to the Configuration/Setup Utility program.

Administrator password control

The Administrator password is set in the Setup Configuration. Refer to “Using the Configuration/Setup Utility program” on page 19.

Operating system password

An operating system password is very similar to a power-on password and denies access to the computer by an unauthorized user when the password is activated. The computer is unusable until the password is entered and recognized by the computer.

Vital product data

Each computer has a unique Vital Product Data (VPD) code stored in the nonvolatile memory on the system board. After you replace the system board, the VPD must be updated. To update the VPD, see “Flash (BIOS/VPD) update procedure” on page 74.

72 IBM NetVista Type 6838, 6848: Hardware Maintenance Manual

Page 81

Management Information Format (MIF)

Management Information Format (MIF) is a file used to maintain a list of the system unit serial number along with all serialized components (for example, system board, riser card, memory, and processor).

At the time of computer manufacture, the EPROM will be loaded with the serial numbers of the system and all major components. The customer will have access to the MIF file via the DMI MIF Browser that is installed with the preload and is also available on the SSCD that is provided with the system.

A company called Retain-a-Group is a central data warehouse offering serial number data management. Retain-a-Group acts as a focal point to law enforcement. The customer has the option to purchase serial number information and services from Retain-a-Group. It is the customer’s responsibility to maintain the MIF file and to inform Retain-a-Group of any changes to the file.

Some customers may request their servicers to assist them in maintaining the MIF file when serialized components are replaced during hardware service. This assistance is between the customer and the servicer. The servicer can use the DMI MIF Browser to update the MIF information in the EPROM. It is anticipated that some servicers might charge for this service.

To update the EPROM using the DMI MIF Browser, use the following procedure.

1. Click Start from the desktop, then Programs.

2. Select IBM SystemView Agent

3. Select the Serial Number Information icon

4. Click the plus sign to expand.

5. Select the component you want to view or edit.

6. Double click on the component you want to change.

7. Enter new data in the Value field, then click Apply.

Alert on LAN

BIOS levels

Alert on LAN provides notification of changes in the computer, even when the computer power is turned off. Working with DMI and Wake on LAN technologies, Alert on LAN helps to manage and monitor the hardware and software features of the computer. Alert on LAN generates notifications to the server of these occurrences:

v Computer disconnected from the network v Computer unplugged from the power outlet v All POST errors v Operating system or POST hang condition

Alert on LAN events are configured to be Enabled or Disabled from the LAN server only, and not from the computer. See the LAN administrator for configuration status information.

An incorrect level of BIOS can cause false error and unnecessary FRU replacement. Use the following information to determine the current level of BIOS installed in the computer, the latest BIOS available for the computer, and where to obtain the latest level of BIOS.

Note: The service procedures are designed to help you isolate problems. They are

written with the assumption that you have model-specific training on all computers, or that are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety: v Observe good housekeeping in the area of the machines during and after

maintenance.

v 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. Do not attempt to lift any objects that

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

v Do not perform any action that causes hazards to the customer, or that makes

the equipment unsafe.

v Before you start the machine, ensure that other service representatives and the

customer’s personnel are not in a hazardous position.

v Place removed covers and other parts in a safe place, away from all personnel,

while you are servicing the machine.

v Keep your tool case away from walk areas so that other people will not trip over

it.

v 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.

v Insert the ends of your necktie or scarf inside clothing or fasten it with a

nonconductive clip, approximately 8 centimeters (3 inches) from the end.

v Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your

clothing. Remember: Metal objects are good electrical conductors.

v Wear safety glasses when you are: hammering, drilling soldering, cutting wire,

attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.

v After service, reinstall all safety shields, guards, labels, and ground wires.

Replace any safety device that is worn or defective.

v Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION: Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the computer covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have

handles covered with a soft material that does not insulate you when working with live electrical currents.

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.

v Find the room emergency power-off (EPO) switch, disconnecting switch, or

electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.

v Do not work alone under hazardous conditions or near equipment that has

hazardous voltages.

v Disconnect all power before:

– Performing a mechanical inspection – Working near power supplies – Removing or installing main units

v Before you start to work on the machine, unplug the power cord. If you cannot

unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

v If you need to work on a machine that has exposed 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.

– 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 may 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.

– Stand on suitable rubber mats (obtained locally, if necessary) to insulate you

from grounds such as metal floor strips and machine frames.

88 IBM NetVista Type 6838, 6848: Hardware Maintenance Manual

Page 97

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.

v Regularly inspect and maintain your electrical hand tools for safe operational

condition.

v Do not use worn or broken tools and testers. v Never assume that power has been disconnected from a circuit. First, check that it

has been powered-off.

v 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.

v 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.

v 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.)

v If an electrical accident occurs:

– Use caution; do not become a victim yourself. – Switch off power. – Send another person to get medical aid.

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: v Electrical hazards, especially primary power (primary voltage on the frame can

cause serious or fatal electrical shock).

v Explosive hazards, such as a damaged CRT face or bulging capacitor v Mechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

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

2. Power-off the computer. Disconnect the power cord.

Chapter 9. Related service information 89

Page 98

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. The power cord should be the appropriate type as specified in the parts

listings.

c. Insulation must not be frayed or worn.

4. Remove the cover.

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.

Handling electrostatic discharge-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:

v Keep the parts in protective packages until they are inserted into the product. v Avoid contact with other people. v Wear a grounded wrist strap against your skin to eliminate static on your body. v Prevent the part from touching your clothing. Most clothing is insulative and

retains a charge even when you are wearing a wrist strap.

v 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.

v Select a grounding system, such as those listed below, to provide protection that

meets the specific service requirement.

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 system. You can use coax or connector-outside shells on these systems.

– Use the round ground-prong of the ac plug on ac-operated computers.
