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: 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 tools overview” on
page 17.
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.

What your IBM Netfinity 5100 offers
The unique design of your server takes advantage of
advancements in symmetric multiprocessing (SMP), data
storage, Your server combines:
v Impressive performance using an innovative approach to
SMP
Your server supports up to two Pentium III
microprocessors. Your server comes with one
microprocessor installed; you can install an additional
microprocessor to enhance performance and provide
SMP capability.
v Large data-storage and hot-swap capabilities
All models of the server support up to six hot-swap hard
disk drives. This hot-swap feature enables you to
remove and replace hard disk drives without turning off
the server.
v Redundant power capabilities
The standard 250-watt power supply in your server can
handle a load of up to 250 watts. By replacing the
power backplane with the optional backplane that
provides hot-swap capability to the power supplies, you
can install a second, optional power supply. This
General information
5
provides a full 500 watts of power. If the average load
on your server is less than 250 watts and a problem
occurs with one of the power supplies, the other power
supply can handle the load (redundant power). If the
average load on your server is greater than 250 watts,
and you have installed a second power supply, you can
install a third, optional power supply to provide
redundancy.
The OVERCURRENT light emitting diode (LED) on the
system board is lit when the power load is 250 watts or
greater with two power supplies, or when the power load
is 500 watts or greater with three power supplies.
v Large system memory
The memory bus in your server supports up to 4 GB of
system memory. The memory controller provides error
correcting code (ECC) support for up to four industry
standard PC133, 3.3 V, 168-pin, 8-byte, registered,
synchronous-dynamic-random access memory (SDRAM)
DIMMs (Intel PC-Registered SDIMM Specifications,
Revision 1.0 or later), synchronous, dual inline memory
modules.
v System-management capabilities
Your server comes with a Netfinity Advanced System
Management Processor on the system board. This
processor, in conjunction with the Netfinity Manager
™
provided on your ServerGuide CDs, allows 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.
Refer to the Advanced System Management section for
more information.
v Integrated network environment support
Your server comes with an Ethernet controller on the
system board. This Ethernet controller 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 allows 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
6 : Netfinity 5100 Type 8658 Models 11Y, 21Y, 31Y,
41Y,51Y,1RY,2RY,3RY,4RY,5RY
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 IBM Netfinity
servers provide programs to help you set up your server
and install the network operating system (NOS). The
ServerGuide program detects the hardware options
installed, and provides the correct configuration program
and device drivers. In addition, the ServerGuide CDs
include a variety of application programs such as IBM
Update Connector to help keep your server BIOS and
microcode updated, and IBM Netfinity Manager for
systems management.
For more information about the ServerGuide CDs, see
the ServerGuide and Netfinity Manager Information
section.
Your server is designed to be cost-effective, powerful, and
flexible. It uses peripheral component interconnect (PCI)
bus architecture to provide compatibility with a wide range
of existing hardware devices and software applications.
As always, your IBM server meets stringent worldwide
certifications for power, electromagnetic compatibility
(EMC), and safety. Refer to the ‘Safety Information’
section. for additional information.
Reliability, availability, and serviceability
features
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
your server; that your server is available when you want to
use it; and that should a failure occur, you can easily
diagnose and repair the failure with minimal inconvenience.

Diagnostics
This section provides basic troubleshooting information to
help you resolve some common problems that might occur
with your server.
Diagnostic tools overview
The following tools are available to help you identify and
resolve 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 error codes” on
page 171 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
your server. By following the path of lights, you can
quickly identify the type of system error that occurred.
See “Light path diagnostics” on page 18 and the table in
“Information panel system error LED” on page 162 for
more information.
v 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 your server. See
“Diagnostic programs and error messages” on page 20
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, a single
beep sounds, the first screen of your 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 your screen. See “Beep
Symptoms” on page 159 and “POST error codes” on
page 171 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.
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 Logs from the main menu.
Small computer system interface
messages
The table in “SCSI error codes” on page 178 lists actions
to take if you receive a SCSI error message.
Note: If your 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.
Identifying problems using status LEDs
If the System Error light in the operator information panel
on the front of the server is on, one or more LEDs inside
the server or on the power supplies will be on. Use the
light path diagnostics to identify the type of error that
occurred.
Light path diagnostics
You can use the light path diagnostics built into your server
to quickly identify the type of system error that occurred.
Your server is designed so that any LEDs that are
illuminated remain illuminated when the server shuts down
as long as the AC power source is good and the power
supplies can supply +5V dc current to the server. This
18 : Netfinity 5100 Type 8658 Models 11Y, 21Y, 31Y,
41Y,51Y,1RY,2RY,3RY,4RY,5RY
feature helps you isolate the problem if an error causes the
server to shut down. See “Light path diagnostics table”.
Power supply LEDs
The AC and DC Power LEDs on the power supply provide
status information about the power supply. See “Power
supply LED errors” on page 170.
Diagnostics panel
The following illustration shows the LEDs on the
diagnostics panel on the system board. See “Light path
diagnostics table” below for information on identifying
problems using these LEDs.

Light path diagnostics table
The System Error LED on the operator information panel is
lit when certain system errors occur. If the System Error
LED on your server is lit, use the table in “Information
panel system error LED” on page 162 to help determine
the cause of the error and the action you should take.
Diagnostics

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 your server.
Diagnostic error messages indicate that a problem exists;
they are not intended to be used to identify a failing part.
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.
