General checkout
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system bsoard. 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, hard drives,
and parallel port. 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. 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.
2. If multiple error codes are displayed, diagnose the first error code displayed.
3. If the computer hangs with a POST error, go to the “Symptom-to-FRU index”
on page 119.
4. If the computer hangs and no error is displayed, go to “Undetermined
problems” on page 142.
5. Power supply problems, see “Symptom-to-FRU index” on page 119.
6. Safety information, see “Safety information” on page 152.
7. For intermittent problems, check the error log; see “POST error messages” on
page 12.
1. IS THE SYSTEM PART OF A CLUSTER?
YES. Schedule maintenance with the customer. Shut down all systems related to
the cluster. Run storage test.
NO. Go to step 2.
© Copyright IBM Corp. 1999 1
2. THE SYSTEM IS NOT PART OF A CLUSTER.
v Power-off the computer and all external devices.
v Check all cables and power cords.
v Set all display controls to the middle position.
v Power-on all external devices.
v Power-on the computer.
v Record any POST error messages displayed on the screen. If an error is
displayed, look up the first error in the “POST error codes” on page 131.
v Check the information LED panel System Error LED; if on, see “Diagnostic
panel LEDs” on page 122.
v Check the System Error Log. If an error was recorded by the system, see
“Symptom-to-FRU index” on page 119.
v Start the Diagnostic Programs. See “Diagnostic programs and error
messages” on page 12.
v Check for the following responses:
a. One beep.
b. Readable instructions or the Main Menu.
3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in “Symptom-to-FRU index” on page 119.
YES. Run the Diagnostic Programs. If necessary, refer to “Diagnostic programs and
error messages” on page 12.
If you receive an error, go to “Symptom-to-FRU index” on page 119.
If the diagnostics completed successfully and you still suspect a problem, see
“Undetermined problems” on page 142.

Server features
The unique design of the server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory management. The server
combines:
v Impressive performance using an innovative approach to SMP
The server supports up to four Pentium III Xeon microprocessors. The server
comes with one microprocessor installed; you can install additional
microprocessors to enhance performance and provide SMP capability.
v Large data-storage and hot-swap capabilities
All models of the server support up to 10 slim-high or 7 half-high hot-swap
hard disk drives. This hot-swap feature enables you to remove and replace hard
disk drives without turning off the server.
v Large system memory
The memory bus in the server supports up to 16 GB of system memory. The
memory controller provides error correcting code (ECC) support for up to 16
industry-standard, 3.3 V, 168-pin, 8-byte, registered, dual inline memory modules
(DIMMs).
v System-management capabilities
The server comes with a Netfinity Advanced System Management Processor on
the system board. This processor, in conjunction with the Netfinity Manager
software provided on the ServerGuide CDs, enables you to manage the functions
of the server locally and remotely. The Netfinity Advanced System Management
Processor also provides system monitoring, event recording, and dial-out alert
capability.
Note: The Netfinity Advanced System Management Processor is sometimes
referred to as the service processor.
v Integrated network environment support
The server comes with an Ethernet controller. This Ethernet controller on the
system board has an interface for connecting to 10-Mbps or 100-Mbps networks.
The server automatically selects between 10BASE-T and 100BASE-TX. The
controller provides full-duplex (FDX) capability, which enables simultaneous
transmission and reception of data on the Ethernet local area network (LAN).
v Redundant network-interface card
The addition of an optional, redundant network interface card (NIC) provides a
failover capability to a redundant Ethernet connection. If a problem occurs with
the primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant NIC. This switching
occurs without data loss and without user intervention.
v IBM ServerGuide CDs
The ServerGuide CDs included with the Netfinity server provide programs to
help you set up the server and install the network operating system (NOS). The
ServerGuide program detects the hardware options that are installed, and
provides the correct configuration programs and device drivers. In addition, the
ServerGuide CDs include a variety of application programs for the server.
General information 5
Reliability, availability, and serviceability
Three of the most important features in server design are reliability, availability,
and serviceability (RAS). These factors help to ensure the integrity of the data
stored on the server; that the server is available when you want to use it; and that

(ROM) on the system board. These programs are the primary method of testing
the major components of the server. See “Diagnostic programs and error
messages” on page 12 for more information.
v Light path diagnostics
Your server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the light-path diagnostics that are
built into the server. By following the path of lights, you can quickly identify the
type of system error that occurred. See “Light path diagnostics” on page 15 for
more information.
v Error symptoms
These charts list problem symptoms, along with suggested steps to correct the
problems. See the “Diagnosing errors” on page 22 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.
© Copyright IBM Corp. 1999 11
If POST finishes without detecting any problems, a single beep sounds, the first
screen of the operating system or application program appears, and the System
POST Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message
appears on the screen. See “POST beep codes” and “POST error messages” for
more information.
Notes:
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 codes
POST generates beep codes to indicate successful completion or the detection of a
problem.
v One 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 119.
POST error messages
POST error messages occur during startup when POST finds a problem with the
hardware or detects a change in the hardware configuration. For a list of POST
errors, see “POST error codes” on page 131.
Event/error logs
The POST error log contains the three most recent error codes and messages that
the system generated during POST. The System Event/Error Log contains all error
messages issued during POST and all system status messages from the Netfinity
Advanced System Management Processor.
To view the contents of the error logs, start the Configuration/Setup Utility
program; then, select Event/Error Logsfrom the main menu.
Small computer system interface messages
If you receive a SCSI error message, see “SCSI error codes” on page 138.
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 SCSISelect Utility.
Diagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of the server.
12 Hardware Maintenance Manual: Netfinity 7100 – Type 8666
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 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
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
information.
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.
Aborted
This result occurs when the test could not proceed because of the
system configuration.
Diagnostics 13
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
This is additional information that you can use to analyze the problem.
Starting the diagnostic programs
You can press F1 while running the diagnostic programs to obtain Help
information. You also can press F1 from within a help screen to obtain online
documentation from which you can select different categories. To exit Help and
return to where you left off, press Esc.
To start the diagnostic programs:
1. Turn on the server and watch the screen.
Note: To run the diagnostic programs, you must start the server with the
highest level password that is set. That is, if an administrator password
is set, you must enter the administrator password, not the power-on
password, to run the diagnostic programs.
2. When the message F2 for Diagnostics appears, press F2.
3. Type in the appropriate password when prompted; then, press Enter.
4. Select either Extended or Basic from the top of the screen.
5. When the Diagnostic Programs screen appears, select the test you want to run
from the list that appears; then, follow the instructions on the screen.
Notes:
a. If the server stops during testing and you cannot continue, restart the server
and try running the diagnostic programs again. If the problem persists,
flash server with the latest diagnostics code and run the test again.
b. The keyboard and mouse (pointing device) tests assume that a keyboard
and mouse are attached to the server.
c. If you run the diagnostic programs with no mouse attached to the server,
you will not be able to navigate between test categories using the Next Cat
and Prev Catbuttons. All other functions provided by mouse-selectable
buttons are also available using the function keys.
d. You can run the USB interface test and the USB external loopback test only
if there are no USB devices attached.
e. You can view server configuration information (such as system
configuration, memory contents, interrupt request (IRQ) use, direct memory
access (DMA) use, device drivers, and so on) by selecting Hardware Info
from the top of the screen.
When the tests have completed, you can view the Test Log by selecting Utility
from the top of the screen.
If the hardware checks out OK but the problem persists during normal server
operations, a software error might be the cause. If you suspect a software problem,
refer to the information that comes with the software package.
14 Hardware Maintenance Manual: Netfinity 7100 – Type 8666
Viewing the test log
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 3.
To view the test log:
1. Turn on the server and watch the screen.
If the server is on, shut down the operating system and restart the server.
2. When the message F2 for Diagnostics appears, press F2.
If a power-on password or administrator password is set, the server prompts
you for it. Type in the appropriate password; then, press Enter.
3. When the Diagnostic Programs screen appears, select Utility from the top of
the screen.
4. Select View Test Log from the list that appears; then, follow the instructions on
the screen.
The system maintains the test-log data while the server 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 125. 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.
Light path diagnostics
The server has LEDs to help you identify problems with some server components.
These LEDs are part of the light path diagnostics built into the server. By following
the path of lights you can quickly identify the type of system error that occurred.

Light path diagnostics
You can use the light path diagnostics built into the server to quickly identify the
type of system error that occurred. Your server is designed so that LEDs remain
illuminated when the server shuts down, as long as the power supplies are
operating properly. This feature helps you to isolate the problem if an error causes
the server to shut down.
If the system error LED (on the information LED panel) is not lit and no
diagnostics panel LEDs are lit, it means that the light path diagnostics have not
detected a system error.
If the system error LED (on the information LED panel) is lit, it means that a
system error was detected. Check to see which of the LEDs on the diagnostics
panel inside the server are lit and refer to the following table:
Table 1. Light path diagnostics
LED Cause Action
None The system error log is 75% or
more full; a PFA alert was
logged; or a failure occurred
on the I2C bus.
SMI A systems management event
occurred.
NMI A nonmaskable interrupt

PCIC LED will probably also
be on.
SP The service processor has
failed.
Check the system error log and correct any
problems. See “Choices available from the
Configuration/Setup main menu” on page 31
for information about clearing the error log.
Disconnecting the server from all power
sources for at least 20 seconds will turn off
the system error LED.
Restart the server.
1. If the PCIA, PCIB, or PCIC LED is not on,
restart the server.
If the problem persists, try to determine the
failing adapter by removing one adapter at a
time and restarting the server after each
adapter is removed.
1. Run service processor diagnostics.
2. Replace Legacy I/O board.

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 system 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 system is at minimum configuration
required for power on (see ″Minimum operating requirements″ on page 131).
4. Reconnect the AC cord and power on the system. If the system powers up
successfully, replace adapters and devices one at a time until the problem is
isolated. If system 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 system to power up (see page 131). For specific problems, see “Power error
messages” on page 139.

Temperature checkout
Proper cooling of the system is important for proper operation and system
reliability. For a typical Netfinity 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 top 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 top 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
In addition, ensure that the environmental specifications for the system are met.
See “Features and specifications” on page 3.
For more information on specific temperature error messages, see “Temperature
error messages” on page 138.
Recovering BIOS
If the BIOS code in the server has become corrupted, such as from a power failure
during a flash update, you can recover the BIOS using the recovery boot block and
a BIOS flash diskette.
Note: You can obtain a BIOS flash diskette from one of the following sources:
The flash memory of the server consists of a primary page and a backup page. The
J56 jumper controls which page is used to start the server. If the BIOS in the
primary page is corrupted, you can use the backup page to start the server; then
boot the BIOS Flash Diskette to restore the BIOS to the primary page.
To recover the BIOS:
v Use the ServerGuide program to make a BIOS flash diskette.
v Download a BIOS flash diskette from the World Wide Web. Go to
http://www.pc.ibm.com/support/, select IBM Server Support, and make
the selections for the server.
1. Turn off the server and peripheral devices and disconnect all external cables
and power cords; then, remove the cover.
2. Locate jumper J56 on the processor board (see “Processor board jumpers” on
page 42).
3. Move J56 to pins 1 and 2 to enable secondary boot block page.
4. Insert the BIOS flash diskette into the diskette drive.
5. Restart the server.
