Chapter 1. General checkout

The server diagnostic programs are stored on CD-ROM. These programs are the
primary method of testing the major components of the server: the system board,
Ethernet controller, video controller, RAM, keyboard, mouse (pointing device),
diskette drive, serial ports, and hard drives. You can also use them to test some
external devices. See “Diagnostic programs and error messages” on page 12.

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

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

A failed system might be part of a shared DASD cluster (two or more systems
sharing the same external storage device(s)). Prior to running diagnostics, verify
that the failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

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

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

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

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

Notes:

1. Safety information, see “Safety information” on page 75.

2. For systems that are part of a shared DASD cluster, run one test at a time in

looped mode. Do not run all tests in looped mode, as this could enable the
DASD diagnostic tests.

3. If multiple error codes are displayed, diagnose the first error code displayed.

4. If the computer hangs with a POST error, go to “POST error codes” on page 69.

10 Hardware Maintenance Manual: xSeries 300

Chapter 3. Diagnostics

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

If you cannot locate and correct the problem using the information in this section,
refer to Chapter 7, “Symptom-to-FRU index” on page 63 for more information.

Diagnostic tools overview

The following tools are available to help you identify and resolve hardware-related
problems:

v POST beep codes

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

v Diagnostic programs and error messages

The server diagnostic programs are provided on the IBM Enhanced Diagnostics
CD. These programs test the major components of the server. See “Diagnostic
programs and error messages” on page 12 for more information.

POST

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

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

Note:

1. If you have a power-on password or administrator 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

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 indicates that POST detected a problem. For more

information, see “Beep symptoms” on page 63“.

POST error messages

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

© Copyright IBM Corp. 2000 11

Repeating long beeps

Indicates that a memory error has occurred. Ensure that all DIMMs 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.

For a list of POST errors, see “POST error codes” on page 69.

Small computer system interface messages (some models)

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

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

indicates that the BIOS is not installed.

You will get these messages only when running the SCSI Select 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 server.

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.

Diagnostic programs and error messages

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

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.

12 Hardware Maintenance Manual: xSeries 300

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

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

iii is the three-digit device ID.
date is the date that the diagnostic test was run and the error recorded.
cc is the check digit that is 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.
User Aborted

Not Applicable

Aborted

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

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

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

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

Chapter 3. Diagnostics 13

Test Specific String

This is additional information that is used to analyze the problem.

Starting the diagnostic programs

The IBM Enhanced Diagnostics programs will isolate your server 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 the 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.

An IBM Enhanced Diagnostics CD comes with the server. You can also download
the latest image of the diagnostics from the World Wide Web at

The test log records data about system failures and other pertinent information.
The test log will not contain any information until after the diagnostic program has
run.

Note: If you already are running the diagnostic programs, begin with step 4

1. Insert the IBM Enhanced Diagnostics CD.

2. Turn on the system and watch the screen.

If the system is on, shut down your operating system and restart the system.

3. If a power-on password is set, the system prompts you for it. Type in the
appropriate password; then, press Enter.

4. Run the appropriate diagnostics program and when the Diagnostic Programs
screen appears, select Utility.

5. Select View Test Log from the list that appears; then, follow the instructions on
the screen.

6. You can save the test log to a file on a diskette or to your hard disk drive.

Note: The system maintains the test-log data while the system is powered on.

When you turn off the power to the server, the test log is cleared.

Diagnostic error message tables

For descriptions of the error messages that might appear when you run the
diagnostic programs, see “Diagnostic error codes” on page 63. If diagnostic error
messages appear that are not listed in those tables, make sure that the server has
the latest levels of BIOS, Advanced System Management Processor, ServeRAID,
and diagnostics microcode installed.

Chapter 3. Diagnostics 15

Power checkout

Power problems can be difficult to troubleshoot. For instance, a short circuit can
exist anywhere on any of the power distribution busses. 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. Power off the server and disconnect the AC cord(s).

2. Check for loose cables in the power subsystem. Also check for short circuits, for

instance 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 server is at minimum configuration required
for power on (see ″Minimum operating requirements″ on page 70).

4. Reconnect the AC cord and power on the server. If the server powers up
successfully, replace adapters and devices one at a time until the problem is
isolated. If server does not power up from minimal configuration, replace FRUs
of minimal configuration one at a time until the problem is isolated.

To use this method it is important to know the minimum configuration required
for a server to power up (see page 70).

16 Hardware Maintenance Manual: xSeries 300

Recovering BIOS code

If the BIOS code has become damaged, such as from a power failure during a flash
update, you can recover the BIOS using the boot block jumper and a BIOS flash
diskette. The boot block jumper selects between normal BIOS mode and flash
recovery mode. In the normal position, the jumper will be installed on pins 2 and

3. In the recovery position, the jumper will be installed on pins 1 and 2.

There are two choices when flashing BIOS. If you select flashing to Server mode,
internal only COM PORT 2 and USB keyboard and mouse emulation will be OFF
by default. These can be turned on, either individually or both, by going into F1
setup and turning them on. This will require a reboot. If you select flashing to
Appliance mode, internal only COM PORT 2 and USB keyboard and mouse
emulation will be ON by default. They can be turned off, either individually or
both, by going into F1 setup and turning them off. This will require a reboot.

If the only US devices attached are keyboard and mouse and they are not working,
investigate the F1 setup settings for these options. You can use a USB keyboard to
press F1 and get into setup.

Note: You can obtain a BIOS flash diskette from one of the following sources:

v Use the ServerGuide program to make a BIOS flash diskette.
v Download files to make a BIOS flash diskette from the World Wide Web.

Go to http://www.ibm.com/pc/support/, select IBM System Support,
and then make the selections for your system.

Complete the following steps to recover the BIOS code:

1. Turn off the server and peripheral devices and disconnect all external cables
and power cords; then, remove the cover, see “Removing the cover” on
page 38.

Chapter 3. Diagnostics 17

2. Locate jumper JROM1 on the system board.

3. Move the JROM1 jumper to the alternate position (pins 1 and 2) to enable the

BIOS recovery mode.

4. Reinstall the cover, see “Installing the cover” on page 53.

5. Reconnect all external cables and power cords and turn on the peripheral

devices.

6. Insert the BIOS flash diskette in the diskette drive.

7. Restart the server. The BIOS begins the power-on self-test.

8. The BIOS flash utility automatically starts.

9. When prompted as to whether you want to save the current code to a

diskette, type N.

10. When prompted, type Y to continue the flash process.

11. The system automatically starts the flash utility a second time.

12. When prompted as to whether you want to save the current BIOS code, stop

the process by removing the BIOS flash diskette from the diskette drive.

13. Turn off the server and peripheral devices and disconnect all external cables
and power cords; then, remove the cover, see “Removing the cover” on
page 38.

14. Move the JROM1 jumper to the normal position (pins 2 and 3) to return to
normal startup mode.

15. Reinstall the cover, see “Installing the cover” on page 53.

16. Reconnect all external cables and power cords and turn on the peripheral

devices.

18 Hardware Maintenance Manual: xSeries 300

Clearing CMOS

17. Restart the server, which should start up normally.

If you need to erase configuration information, you must move the CMOS jumper.
See the illustration in “Recovering BIOS code” on page 17 for the location of the
CMOS jumper.

The default position is a jumper installed on pins 1 and 2. Before you change the
position of this jumper, you must turn off the server and peripheral devices, and
disconnect all external cables and power cords. Remove the cover and then move
the jumper to pins 2 and 3.

After moving the jumper, wait at least 5 minutes for the CMOS information to
clear.

Changing the position of this jumper erases all configuration and setup
information, including the power-on and administrator passwords. Therefore, you
must reconfigure the server after clearing CMOS memory (see Chapter 4,
“Configuring the server” on page 29). If possible, record your server configuration
information before moving the CMOS jumper.

After you clear the CMOS information, move the jumper back to its normal
position (pins 1 and 2). Reconnect the external cables and power cords; then, turn
on the peripheral devices and the server.

Replacing the battery

When replacing the battery, you must replace it with a lithium battery of the same
type from the same manufacturer. To avoid possible danger, read and follow the
safety statement below.

To order replacement batteries, call 1-800-772-2227 within the United States, and
1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada, call
your IBM reseller or IBM marketing representative.

Note: After you replace the battery, you must reconfigure your system and reset

the system date and time.

Chapter 3. Diagnostics 19

CAUTION:
When replacing the battery, use only IBM Part Number 33F8354 or an equivalent
type battery recommended by the manufacturer. If your server has a module
containing a lithium battery, replace it only with the same module type made by
the same manufacturer. The battery contains lithium and can explode if not
properly used, handled, or disposed of.

Do not:

v Throw or immerse into water
v Heat to more than 100°C (212°F)
v Repair or disassemble

Dispose of the battery as required by local ordinances or regulations.

Do the following to replace the battery:

1. Read “Before you begin” on page 36, and follow any special handling and

installation instructions supplied with the replacement battery.

2. Turn off the server and peripheral devices and disconnect all external cables

and power cords; then, remove the server cover.

3. Remove the battery:

a. Use one finger to lift the battery clip over the battery.
b. Use one finger to slightly slide the battery out from its socket. The spring

mechanism will push the battery out toward you as you slide it from the
socket.

c. Use your thumb and index finger to pull the battery from under the battery

clip.

d. Ensure that the battery clip is touching the base of the battery socket by

pressing gently on the clip.

4. Do the following to insert the new battery:

a. Tilt the battery so that you can insert it into the socket under the battery

clip.

b. As you slide it under the battery clip, press the battery down into the

5. Reinstall the server cover and connect the cables.

6. Turn on the server.

20 Hardware Maintenance Manual: xSeries 300

7. Start the Configuration/Setup Utility program and set configuration
parameters.

v Set the server date and time.
v Set the power-on password.
v Reconfigure your server.

Temperature checkout

Proper cooling of the server is important for proper operation and server reliability.
For a typical xSeries server, you should make sure:

v Each of the drive bays has either a drive or a filler panel installed
v Each of the power supply bays has either a power supply or a filler panel

installed

v The server cover is in place during normal operation
v There is at least 50 mm (2 inches) of ventilated space at the sides of the server

and 100 mm (4 inches) at the rear of the server

v The server cover is removed for no longer than 30 minutes while the server is

operating

v The processor housing cover covering the processor and memory area is

removed for no longer that ten minutes while the server is operating

v A removed hot-swap drive is replaced within two minutes of removal
v Cables for optional adapters are routed according to the instructions provided

with the adapters (ensure that cables are not restricting air flow)

v The fans are operating correctly and the air flow is good
v A failed fan is replaced within 48 hours

Attention:

If using AOL/2 or system supported monitoring software, and you are receiving a
thermal alert with no fan alert, check SYSFA1 and CPUFA2, which are
unmonitored and therefore cannot generate alerts, to make certain that those fans
are connected to planar power and are functional.

If the system powers itself down, the cause maybe an overheated processor
causing a thermal trip. One of your checks should be to ensure that both system
fans and both CPU fans are connected to planar power and are functional.

In addition, ensure that the environmental specifications for the server are met. See
“Features and specifications” on page 4.

Note: The speed of the fans will increase if:

Diagnosing errors

To find solutions to problems that have definite symptoms, see “Error symptoms”

on page 66.

If you cannot find the problem there, go to “Starting the diagnostic programs” on
page 14 to test the server.

v One fan fails.
v Ambient temperature gets too high.

Chapter 3. Diagnostics 21

If you have just added new software or a new option and the server is not
working, do the following before using the error symptoms table:

v Remove the software or device that you just added.
v Run the diagnostic tests to determine if the server is running correctly.
v Reinstall the new software or new device.

Troubleshooting the Ethernet controller

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

Network connection problems

If the Ethernet controller cannot connect to the network, check the following:
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 persists, try a different cable.

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

If you directly connect two workstations (without a hub), or if you are not using
a hub with X ports, use a crossover cable.

Note: To determine whether a hub has an X port, check the port label. If the

label contains an X, the hub has an X port.

v Determine if the hub supports auto-negotiation. If not, try configuring the

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

v Check the LAN activity light (if available) on the front of the server. The LAN

activity light illuminates when the Ethernet controller sends or receives data
over the Ethernet network. If the LAN activity light is off, make sure that the
hub and network are operating and that the correct device drivers are loaded.

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

server.

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

protocol.

v Test the Ethernet controller.

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

Before you begin

Before you begin to install options in the server, read the following information:
v Become familiar with the safety and handling guidelines provided in:

–“Safety information” on page 75;
–“Handling electrostatic discharge-sensitive devices” on page 78; and
–“Safety notices (multi-lingual translations)” on page 79.

These guidelines will help you work safely while working with the server or
options.

36 Hardware Maintenance Manual: xSeries 300

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

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

v Back up all important data before you make changes to disk drives.
v For a list of supported options for the 200, refer to

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

Working inside the server with the power on

The server is designed with safety in mind. Follow these guidelines when you
work inside a server that is turned on:

v Avoid loose-fitting clothing on your forearms. Button long-sleeved shirts before

working inside the server; do not wear cuff links while you are working inside
the server.

v Do not allow your necktie to hang inside the server.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist

watches.

v Remove items from your shirt pocket (such as pens or pencils) that could fall

into the server as you lean over it.

v Avoid dropping any metallic objects, such as paper clips, hair pins, or screws,

into the server.

System reliability considerations

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

compatibility (EMC) shield installed.

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

properly. Leave about 127 mm (5 in.) of space around the front and rear of the
server.

v Cables for optional adapters are routed according to the instructions that are

provided with the adapters.

v A failed fan is replaced within 1 hour.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To
avoid damage, keep static-sensitive devices in their static-protective bag until you
are ready to install them.

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

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

you.

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

device.

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

part of the system unit for at least two seconds. (This drains static electricity
from the package and from your body.)

v Remove the device from its package and install it directly into your system unit

without setting it down. If it is necessary to set the device down, place it on its

Chapter 5. Installing Options 37

static-protective package. (If your device is an adapter, place it component side
up.) Do not place the device on your system unit cover or on a metal table.

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

reduces indoor humidity and increases static electricity.

Removing the cover

Complete the following steps to remove the server cover:

1. Review the information in “Before you begin” on page 36.

2. Turn off the server and all attached devices and disconnect all external cables

and power cords.

Adapter considerations

Before you install adapters, review the following:
v Locate the documentation that comes with the adapter and follow those

instructions in addition to the instructions in this chapter.

v If you need to change the switch settings or jumper settings on your adapter,

follow the instructions that come with the adapter.

v You can install 32-bit full-length or half-length adapters in the expansion slots.

Full-length adapters are installed in slot 1 only; half-length adapters are installed
in either slot 1 or 2.

v Your server supports 5.0 V and universal PCI adapters; it does not support 3.3

V only adapters.

v Your server uses a rotational interrupt technique to configure PCI adapters. You

can use this technique to install PCI adapters that currently do not support
sharing of PCI interrupts.

v The system scans PCI slots to assign system resources. By default the system

starts (boots) the CD-ROM and diskette drives first. Then it starts PCI slot 2, PCI
slot 1, and the integrated Ethernet.

Note: You can use the Configuration/Setup Utility program to change the boot

precedence for your server. Select Start Options from the
Configuration/Setup Utility program main menu.

Chapter 7. Symptom-to-FRU index

This index supports xSeries 300 server. The Symptom-to-FRU lists symptoms,
errors, and the possible causes. The most likely cause is listed first. Use this
Symptom-to-FRU index to help you decide which FRUs to have available when
servicing the computer.

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

Beep symptoms

Currently there are two kinds of beep codes in BIOS. This code indicates that a
video error has occurred and the BIOS cannot initialize the video screen to display
any additional information. This beep code consists of a single long beep followed
by two short beeps. The other code indicates that your DRAM error has occurred.
This beep code consists of a single long repeating beep.

Undetermined problems

You are here because the diagnostic tests did not identify the failure, the Devices
List is incorrect, or the system is inoperative.

Note: A corrupt CMOS can cause undetermined problems.

If power problems are suspected:

1. Power-off the computer.

2. Be sure the system is cabled correctly.

3. Remove or disconnect the following (one at a time) until you find the failure

(power-on the computer and reconfigure each time).

v Any external devices
v Surge suppressor device (on the computer)
v Modem, printer, mouse, or non-IBM devices
v Each adapter
v Drives
v Memory Modules (Minimum requirement = one 128 MB DIMM)

Note: Minimum operating requirements are:

a. 1 Power Supply
b. System Board
c. 1 Microprocessor
d. 1 Terminator Card in Slot 2
e. 1 Memory Module (minimum of 1 DIMM in slot labeled DIMM 1)

4. Power-on the computer. If the problem remains, suspect the following FRUs in

the order listed:

Power Supply
System Board

Notes:

1. If the problem goes away when you remove an adapter from the system, and
replacing that adapter does not correct the problem, suspect the system board,
then the power supply.

2. If you suspect a networking problem and all the system tests pass, suspect a
network cabling problem external to the system.

Chapter 9. Related service information

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 mobile 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 server 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.

76 Hardware Maintenance Manual: xSeries 300

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 77

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.

78 Hardware Maintenance Manual: xSeries 300

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct
system function. Proper grounding of the electrical outlet can be verified by a
certified electrician.
