Guidelines for trained service technicians

This section contains information for trained service technicians.

Inspecting for unsafe conditions

Use the information in this section to help you identify potential unsafe conditions in
an IBM® product that you are working on. Each IBM product, as it was designed
and manufactured, has required safety items to protect users and service
technicians from injury. The information in this section addresses only those items.
Use good judgment to identify potential unsafe conditions that might be caused by
non-IBM alterations or attachment of non-IBM features or options that are not
addressed in this section. If you identify an unsafe condition, you must determine
how serious the hazard is and whether you must correct the problem before you
work on the product.

Consider the following conditions and the safety hazards that 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 a bulging or leaking

capacitor.

v Mechanical hazards, such as loose or missing hardware.

inspect the product for potential unsafe conditions, complete the following steps:

To

1. Make sure that the power is off and the power cord is disconnected.

2. Make sure that the exterior cover is not damaged, loose, or broken, and
observe any sharp edges.

3. Check the power cord:

v Make sure that the third-wire ground connector is in good condition. Use a

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

v Make sure that the power cord is the correct type, as specified in “Power

cords” on page 92.

v Make sure that the insulation is not frayed or worn.

Remove the cover.

4.

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

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

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

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

viii System x3400 Types 7973, 7974, 7975, and 7976: Problem Determination and Service Guide

Guidelines for servicing electrical equipment

Observe the following guidelines when servicing electrical equipment:

v Check the area for electrical hazards such as moist floors, nongrounded power

extension cords, power surges, and missing safety grounds.

v Use only approved tools and test equipment. Some hand tools have handles that

are covered with a soft material that does not provide insulation from live
electrical currents.

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

condition. Do not use worn or broken tools or testers.

v Do not touch the reflective surface of a dental mirror to a live electrical circuit.

The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.

v Some rubber floor mats contain small conductive fibers to decrease electrostatic

discharge. Do not use this type of mat to protect yourself from electrical shock.

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

hazardous voltages.

v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical

outlet so that you can turn off the power quickly in the event of an electrical
accident.

v Disconnect all power before you perform a mechanical inspection, work near

power supplies, or remove or install main units.

v Before you work on the equipment, disconnect the power cord. If you cannot

disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.

v Never assume that power has been disconnected from a circuit. Check it to

make sure that it has been disconnected.

v If you have to work on equipment that has exposed electrical circuits, observe

the following precautions:

– Make sure that another person who is familiar with the power-off controls is

near you and is available to turn off the power if necessary.

– When you are working with powered-on electrical equipment, use only one

hand. Keep the other hand in your pocket or behind your back to avoid
creating a complete circuit that could cause an electrical shock.

– When using a tester, set the controls correctly and use the approved probe

leads and accessories for that tester.

– Stand on a suitable rubber mat to insulate you from grounds such as metal

floor strips and equipment frames.

Use extreme care when measuring high voltages.

v

v To ensure proper grounding of components such as power supplies, pumps,

blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.

v If an electrical accident occurs, use caution, turn off the power, and send another

person to get medical aid.

Chapter 2. Diagnostics

This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the server.

If you cannot locate and correct the problem using the information in this chapter,
see “Getting help and technical assistance” on page 183 for more information.

Diagnostic tools

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

v POST beep codes, error messages, and error logs

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 Troubleshooting tables

These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 41.

v Server LEDs

Use the LEDs on the server to diagnose system errors quickly. See “Error LEDs”
on page 55 for more information.

v Diagnostic programs, messages, and error messages

The diagnostic programs are the primary method of testing the major
components of the server. The diagnostic programs are on the IBM Enhanced

Diagnostics CD that comes with the server. See “Diagnostic programs,

messages, and error codes” on page 58 for more information.

POST

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

If a power-on password is set, you must type the password and press Enter, when
prompted, for POST to run.

If POST is completed without detecting any problems, a single beep sounds, and
the server startup is completed.

If POST detects a problem, more than one beep might sound, or an error message
is displayed. See “POST beep codes” on page 18 and “POST error codes” on page
24 for more information.

© Copyright IBM Corp. 2006 17

POST beep codes

A beep code is a combination of short or long beeps or series of short beeps that
are separated by pauses. For example, a “1-2-3” beep code is one short beep, a
pause, two short beeps, and pause, and three short beeps. A beep code indicates
that POST has detected a problem. If no beep code sounds, see “No-beep
symptoms” on page 21.

The following table describes the beep codes and suggested actions to correct the
detected problems.

A single problem might cause more than one error message. When this occurs,
correct the cause of the first error message. The other error messages usually will
not occur the next time POST runs.

Exception: If there are multiple error codes that indicate a microprocessor error,

the error might be in a microprocessor or in a microprocessor socket. See
“Microprocessor problems” on page 47 for information about diagnosing
microprocessor problems.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem

is solved.

v See Chapter 3, “Parts listing, System x3400 Types 7973, 7974, 7975 and 7976,” on page 87 to determine

Error logs

The POST error log contains the three most recent error codes and messages that
were generated during POST. The BMC log and the system-event log contain
messages that were generated during POST and all system status messages from
the service processor.

The following illustration shows an example of a BMC log entry.

BMC System Event Log

---------------------------------------------------------­Get Next Entry
Get Previous Entry
Clear BMC SEL

Entry Number= 00005 / 00011
Record ID= 0005
Record Type= 02
Timestamp= 2005/01/25 16:15:17
Entry Details: Generator ID= 0020

Sensor Type= 04
Assertion Event
Fan
Threshold
Lower Non-critical - going high

Sensor Number= 40
Event Direction/Type= 01

Event Data= 52 00 1A

The BMC log is limited in size. When the log is full, new entries will not overwrite
existing entries; therefore, you must periodically clear the BMC log through the
Configuration/Setup Utility program (the menu choices are described in the User’s
Guide). When you are troubleshooting an error, be sure to clear the BMC log so
that you can find current errors more easily.

Important: After you complete a repair or correct an error, clear the BMC log to

turn off the system-error LED on the front of the server.

Entries that are written to the BMC log during the early phase of POST show an
incorrect date and time as the default time stamp; however, the date and time are
corrected as POST continues.

Each BMC log entry appears on its own page. To display all of the data for an entry,
use the Up Arrow (↑) and Down Arrow (↓) keys or the Page Up and Page Down
keys. To move from one entry to the next, select Get Next Entry or Get Previous
Entry.

The log indicates an assertion event when an event has occurred. It indicates a
deassertion event when the event is no longer occurring.

Some of the error codes and messages in the BMC log are abbreviated.

If you view the BMC log through the Web interface of the optional Remote
Supervisor Adapter II SlimLine, the messages can be translated.

You can view the contents of the POST error log, the BMC log, and the
system-error log from the Configuration/Setup Utility program. You can view the

22 System x3400 Types 7973, 7974, 7975, and 7976: Problem Determination and Service Guide

38 System x3400 Types 7973, 7974, 7975, and 7976: Problem Determination and Service Guide

Checkout procedure

The checkout procedure is the sequence of tasks that you should follow to
diagnose a problem in the server.

About the checkout procedure

Before performing the checkout procedure for diagnosing hardware problems,
review the following information:

v Read the safety information that begins on page vii.

v The diagnostic programs provide the primary methods of testing the major

components of the server, such as the system board, ethernet controller,
keyboard, mouse (pointing device), serial ports, and hard disk drives. You can
also use them to test some external devices. If you are not sure whether a
problem is caused by the hardware or by the software, you can use the
diagnostic programs to confirm that the hardware is working correctly.

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

one error message. When this happens, correct the cause of the first error
message. The other error messages usually will not occur the next time you run
the diagnostic programs.

Exception: If there are multiple error codes or LEDs that indicate a

microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 47 for
information about diagnosing microprocessor problems.

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

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

– You have identified the failing server as part of a cluster (two or more servers

sharing external storage devices).

– One or more external storage units are attached to the failing server and at

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

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

Important:

If the server is part of a shared hard disk drive cluster, run one test

at a time. Do not run any suite of tests, such as “quick” or “normal” tests,
because this might enable the hard disk drive diagnostic tests.

v If the server is halted and a POST error code is displayed, see “Error logs” on

page 22. If the server is halted and no error message is displayed, see
“Troubleshooting tables” on page 41 and “Solving undetermined problems” on
page 84.

v For information about power-supply problems, see “Solving power problems” on

page 82.

v For intermittent problems, check the error log; see “Error logs” on page 22 and

“Diagnostic programs, messages, and error codes” on page 58.

Chapter 2. Diagnostics 39

Performing the checkout procedure

To perform the checkout procedure, complete the following steps:

1. Is the server part of a cluster?

v No: Go to step 2.
v Yes: Shut down all failing servers that are related to the cluster. Go to step 2.

2. Complete the following steps:

a. Turn off the server and all external devices.

b. Check all cables and power cords.

c. Set all display controls to the middle positions.

d. Turn on all external devices.

e. Turn on the server. If the server does not start, see “Troubleshooting tables”

on page 41.

f. Check the system-error LED on the control panel. If it is lit, check the LEDs

on the system board (see “Error LEDs” on page 55).

Important: If the system-error LED on the front of the server is lit but there

are no other error indications, clear the BMC log. This log does not clear
itself, and if it begins to fill up, the system-error LED will be lit. Also, after you
complete a repair or correct an error, clear the BMC log to turn off the
system-error LED on the front of the server.

g. Check for the following results:

v Successful completion of POST, indicated by a single beep

v Successful completion of startup, indicated by a readable display of the

operating-system desktop

Did a single beep sound and are there readable instructions on the main menu,

3.
or was a POST error code displayed?

v Yes: Find the beep code or error code in “POST beep codes” on page 18 or

“POST error codes” on page 24; if necessary, see “Solving undetermined
problems” on page 84.

v No: Find the failure symptom in “Troubleshooting tables” on page 41; if

necessary, run the diagnostic programs (see “Running the diagnostic
programs” on page 58).

– If you receive an error, see “Diagnostic error codes” on page 60.

– If the diagnostic programs were completed successfully and you still

suspect a problem, see “Solving undetermined problems” on page 84.

Checkpoint codes (trained service technicians only)

A checkpoint code identifies the check that was occurring when the server stopped;
it does not provide error codes or suggest replacement components. Checkpoint
codes are shown on the checkpoint display, which is on the system board. By using
the checkpoint display, you do not have to wait for the video to initialize each time
that you restart the server.

There are two types of checkpoint codes: complex programmable logic device
(CPLD) hardware checkpoint codes and BIOS checkpoint codes. The BIOS
checkpoint codes might change when the BIOS code is updated.

Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms.

If you cannot find the problem in these tables, see “Running the diagnostic
programs” on page 58 for information about testing the server.

If you have just added new software or a new optional device and the server is not
working, complete the following steps before using the troubleshooting tables:

1. Check the LEDs on the control panel or the system board (see “Error LEDs” on
page 55).

2. Remove the software or device that you just added.

error LED

The server is designed so that LEDs remain lit when the server is connected to an
ac power source but is not turned on, provided that the power supply is operating
correctly. This feature helps you to isolate the problem when the operating system
is shut down.

Many errors are first indicated by a lit system-error LED on the control-panel
assembly of the server. If this LED is lit, one or more LEDs elsewhere in the server
might also be lit and can direct you to the source of the error.

Important: If the system-error LED on the front of the server is lit but there are no

other error indications, clear the BMC system event log. This log does not clear
itself, and if it begins to fill up, the system-error LED will be lit. Also, after you
complete a repair or correct an error, clear the BMC system event log to turn off the
system-error LED on the front of the server.

Before working inside the server to view the LEDs, read the safety information that
begins on page vii and “Handling static-sensitive devices” on page 97.

If an error occurs, view the server LEDs in the following order:

1. Check the control-panel assembly on the front of the server. If the system-error

LED is lit, it indicates that an error has occurred.

Chapter 2. Diagnostics 55

2. Check the front and rear of the server to determine whether any component
LEDs are lit.

3. Remove the server cover and look inside the server for lit LEDs. Certain
components inside the server have LEDs that will be lit to indicate the location
of a problem. For example, a DIMM error will light the LED next to the failing
DIMM on the system board.

Look at the system service label on the top of the server, which gives an
overview of internal components. This information can often provide enough
information to correct the error.

Power-supply LEDs

The following minimum configuration is required for the server to start:

v One microprocessor
v Two 512 MB DIMMs
v One power supply
v Power backplane
v Power cord
v ServeRAID SAS adapter
v System board assembly

Diagnostic programs, messages, and error codes

The diagnostic programs are the primary method of testing the major components
of the server. As you run the diagnostic programs, text messages and error codes
are displayed on the screen and are saved in the test log. A diagnostic text
message or error code indicates that a problem has been detected; to determine
what action you should take as a result of a message or error code, see the table in
“Diagnostic error codes” on page 60.

Running the diagnostic programs

To run the diagnostic programs, complete the following steps:

1. If the server is running, turn off the server and all attached devices.

2. Turn on all attached devices; then, turn on the server.

3. When you see Press F1 For Configuration/Setup, press the F1 key.

4. When the Configuration/Setup Utility menu appears, select Start Options.

5. From the Start Options menu, select Startup Sequence Options.

6. Note the device that is selected as the first startup device. Later, you must

8. Press Esc two times to return to the Configuration/Setup Utility menu.

9. Insert the IBM Enhanced Diagnostics CD in the CD drive.

10. Select Save & Exit Setup and follow the prompts. The diagnostics will load.

11. From the diagnostic programs screen, select the test that you want to run, and
follow the instructions on the screen.

When you are diagnosing hard disk drives, select SCSI Attached Disk Test
for the most thorough test. Select Fixed Disk Test for any of the following
situations:

v You want to run a faster test.

v The server contains RAID arrays not connected to the onboard SAS/SATA

controller.

v The server contains simple-swap SATA hard disk drives not connected to

the integrated SATA controller.

determine what action you should take as a result of a diagnostic text message

To
or error code, see “Diagnostic error codes” on page 60.

If the diagnostic programs do not detect any hardware errors but the problem
remains during normal server operations, a software error might be the cause. If
you suspect a software problem, see the information that comes with your software.

A single problem might cause more than one error message. When this happens,
correct the cause of the first error message. The other error messages usually will
not occur the next time you run the diagnostic programs.

Exception: If there are multiple error codes or LEDs that indicate a microprocessor

error, the error might be in a microprocessor or in a microprocessor socket. See
“Microprocessor problems” on page 47 for information about diagnosing
microprocessor problems.

If the server stops during testing and you cannot continue, restart the server and try
running the diagnostic programs again. If the problem remains, replace the
component that was being tested when the server stopped.

System-error log messages

A system-error log is generated only if a Remote Supervisor Adapter II SlimLine is
installed. The system-error log can contain messages of three types:

Information Information messages do not require action; they record significant

system-level events, such as when the server is started.

Warning Warning messages do not require immediate action; they indicate

possible problems, such as when the recommended maximum
ambient temperature is exceeded.

Error Error messages might require action; they indicate system errors,

such as when a fan is not detected.

Each message contains date and time information, and it indicates the source of

the message (POST/BIOS or the service processor).

Note: The BMC log, which you can view through the Configuration/Setup Utility

program, also contains many information, warning, and error messages.

In the following example, the system-error log message indicates that the server
was turned on at the recorded time.

Solving SCSI problems

Note: This information also applies to Serial Attached SCSI (SAS) problems.

For any SCSI error message, one or more of the following devices might be
causing the problem:

v A failing SCSI device (adapter, drive, or controller)

v An incorrect SCSI termination jumper setting

v A missing or incorrectly installed SCSI terminator

v A defective SCSI terminator

v An incorrectly installed cable

v A defective cable

any SCSI error message, follow these suggested actions in the order in which

For
they are listed until the problem is solved:

1. Make sure that external SCSI devices are turned on before you turn on the
server.

2. Make sure that the cables for all external SCSI devices are connected correctly.

3. If an external SCSI device is attached, make sure that the external SCSI
termination is set to automatic.

4. Make sure that the last device in each SCSI chain is terminated correctly.

5. Make sure that the SCSI devices are configured correctly.

Solving power problems

Power problems can be difficult to solve. For example, a short circuit can exist
anywhere on any of the power distribution buses. Usually, a short circuit will cause
the power subsystem to shut down because of an overcurrent condition. To
diagnose a power problem, use the following general procedure:

1. Turn off the server and disconnect all ac power cords.

2. Check for loose cables in the power subsystem. Also check for short circuits, for
example, if a loose screw is causing a short circuit on a circuit board.

3. Remove the adapters and disconnect the cables and power cords to all internal
and external devices until the server is at the minimum configuration that is
required for the server to start (see “Solving undetermined problems” on page
84 for the minimum configuration).

4. Reconnect all ac power cords and turn on the server. If the server starts
successfully, replace the adapters and devices one at a time until the problem is
isolated.

If the server does not start from the minimum configuration, replace the components
in the minimum configuration one at a time until the problem is isolated.
