Laser Safety Information
CAUTION:
This product may contain a CD-ROM which is a class 1 laser product.
Laser Compliance
All lasers are certified in the U.S. to conform to the requirements of DHHS 21 CFR
Subchapter J for class 1 laser products. Outside the U.S., they are certified to be in
compliance with the IEC 825 (first edition 1984) as a class 1 laser product. Consult the
label on each part for laser certification numbers and approval information.
CAUTION:
All IBM laser modules are designed so that there is never any human access to
laser radiation above a class 1 level during normal operation, user maintenance,
or prescribed service conditions. Data processing environments can contain
equipment transmitting on system links with laser modules that operate at
greater than class 1 power levels. For this reason, never look into the end of an
optical fiber cable or open receptacle. Only trained service personnel should
perform the inspection or repair of optical fiber cable assemblies and receptacles.
x Service Guide
Data Integrity and Verification
IBM computer systems contain mechanisms designed to reduce the possibility of
undetected data corruption or loss. This risk, however, cannot be eliminated. Users who
experience unplanned outages, system failures, power fluctuations or outages, or
component failures must verify the accuracy of operations performed and data saved or
transmitted by the system at or near the time of the outage or failure. In addition, users
must establish procedures to ensure that there is independent data verification before
relying on such data in sensitive or critical operations. Users should periodically check
the IBM support websites for updated information and fixes applicable to the system and
related software.

Location Codes
This system unit uses physical location codes in conjunction with AIX location codes to
provide mapping of the failing field replaceable units. The location codes are produced
by the system unit’s firmware and AIX.
Physical Location Codes
Physical location codes provide a mapping of logical functions in a platform (or
expansion sites for logical functions, such as connectors or ports) to their specific
locations within the physical structure of the platform.
Location Code Format
The location code is an alphanumeric string of variable length, consisting of a series of
location identifiers, separated by a dash (-), or slash (/), or a pound sign (#) character.
The series is hierarchical; that is, each location identifier in the string is a physical or
logical child of the one preceding it.
v The - (dash) separator character represents a normal structural relationship where
the child is a separate physical package and it plugs into (or is connected to) the
parent. For example, P1-C1 is a processor card (C1) plugged into a planar (P1), or
P1-M1 is a memory card (M1) plugged into a planar (P1).
v The / (slash) separator character separates the base location code of a function from
any extended location information. A group of logical devices can have the same
base location code because they are all on the same physical package, but may
require extended location information to describe the connectors they support. For
example, P2/S1 describes the location of the serial port 1 controller and its connector
(S1), which is located on planar P2 (its base location code), but the / indicates that
further devices can be connected to it at the external S1 serial connector. The
keyboard controller and its connector likewise have location code P2/K1, which
means they have the same base location code (P2) as serial port 1, but a different
external connector. In contrast, the location code P2-K1 actually points to the device
connected to connector K1; that is, the keyboard. The location code P2/Z1 indicates
an integrated SCSI controller which drives connector Z1, while location codes of
P2-Z1-... point to the actual SCSI bus and devices.
v The # (pound sign) separator character indicates a cable connection between a
connector and parent.
The following are examples:
v P1-C1 identifies processor card C1 plugged into planar P1.
v P1-M1 identifies memory card M1 plugged into planar P1.
v P2/S1 identifies serial port 1 controller on I/O board P2 or the connector for serial
port 1.
v P1-K1 identifies a keyboard attached to connector K1 on planar P1.
v P2/Z1 identifies an integrated SCSI port controller on planar P2 which drives
connector Z1.
v P2-Z1-... points to the actual SCSI bus and devices attached to Z1.
Chapter 1. Reference Information 11
The . (period) identifies sublocations (DIMMs on a memory card or SCSI addresses).
The following are examples:
v P1-M1.4 identifies memory DIMM 4 on memory card 1 plugged into planar P1.
v P1-C1.1 identifies processor 1 on processor card 1 plugged into planar P1.
v P2-Z1-A3.1 identifies a SCSI device with SCSI address of LUN 1 at SCSI ID 3
attached to SCSI bus 1, which is integrated on planar P2.
v P2.1 identifies a riser card plugged into planar P2.
AIX Location Codes
The basic formats of the AIX location codes are as follows:
v For non-SCSI devices/drives:
– AB-CD-EF-GH
v For SCSI devices/drives:
– AB-CD-EF-G,H
Non-SCSI Devices/Drives
For planars, cards, and non-SCSI devices, the location code is defined as follows:
AB-CD-EF-GH
||||
| | | Device/FRU/Port ID
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
v The AB value identifies a bus type or PCI parent bus as assigned by the firmware.
v The CD value identifies adapter number, the adapter’s devfunc number, or physical
location. The devfunc number is defined as the PCI device number times 8, plus the
function number.
v The EF value identifies a connector.
v The GH value identifies a port, address, device, or FRU.
Adapters and cards are identified only with AB-CD.
The possible values for AB are:
00 Processor bus
01 ISA bus
02 EISA bus
03 MCA bus
04 PCI bus used in the case where the PCI bus cannot be identified
05 PCMCIA buses
xy For PCI adapters where x is equal to or greater than 1. The x and y are characters in the
range of 0-9, A-H, J-N, P-Z (O, I, and lower case are omitted) and are equal to the parent
bus’s ’ibm, aix-location’ open firmware property.
The possible values for CD depend on the adapter/card:
12 Service Guide
v For pluggable PCI adapters/cards, CD is the device’s devfunc number (PCI device
number times 8, plus the function number). The C and D are characters in the range
of 0-9, and A-F (hex numbers). Location codes therefore uniquely identify multiple
adapters on individual PCI cards.
v For pluggable ISA adapters, CD is equal to the order of the ISA cards
defined/configured either by SMIT or the ISA Adapter Configuration Service Aid.
v For an integrated ISA adapters, CD is equal to a unique code identifying the ISA
adapter. In most cases, this code is equal to the adapter’s physical location code. In
cases where a physical location code is not available, CD will be FF.
EF is the connector ID. It is used to identify the adapter’s connector to which a resource
is attached.
GH is used to identify a port, device, or FRU. For example:
v For async, devices GH defines the port on the fanout box. The values re 00 a to 15.
v For a diskette drive, H identifies either diskette drive 1 or 2. G is always 0.
v For all other devices, GH is equal to 00.
For an integrated adapter, EF-GH is the same as the definition for a pluggable adapter.
For example, the location code for a diskette drive is 01-D1-00-00. A second diskette
drive is 01-D1-00-01.
SCSI Devices/Drives
For SCSI devices, the location code is defined as follows:
AB-CD-EF-G,H
| | |||
| | | | Logical Unit address of the SCSI Device
| | | Control Unit Address of the SCSI Device
| | Connector ID
| devfunc Number, Adapter Number or Physical Location
Bus Type or PCI Parent Bus
Where AB-CD-EF are the same as non-SCSI devices.
G defines the control unit address of the device. Values of 0 to 15 are valid.

Chapter 2. Diagnostic Overview
The system uses an integrated set of software diagnostic procedures to facilitate
isolation of failing components and system maintenance. This book, along with the
RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems
,isthe
basis of the diagnostic procedures for the system. In particular, Chapter 4,
“Checkpoints” on page 81, Chapter 5, “Error Code to FRU Index” on page 109,
Chapter 6, “Loading the System Diagnostics” on page 175, and Chapter 10, “Parts
Information” on page 293, in this book are important for the trained service
representative to understand and use when isolating a failure on the system.
The manufacturer recommends that systems configured with 4 GB of memory or
greater have access to a 4-mm or 8-mm tape drive for submission of system dump
information if required. This function can be accomplished through locally attached or
network-attached devices, as appropriate.
Maintenance Analysis Procedures (MAPs)
Maintenance Analysis Procedures (MAPs) guide the trained service person through the
system. These MAPs are the entry point for all isolation and error recovery procedures.
The MAPs are consistent with existing procedures and methods. The system uses a set
of integrated procedures, mentioned earlier, to which the MAPs are the primary entry
point.
The MAPS are as follows:
v Entry MAP
v Quick Entry MAP
v Problem Determination MAP
v Power MAP
v Minimum Configuration MAP
The Entry Map is the starting point for problem determination. The purpose of this MAP
is to quickly point to the appropriate MAP or service reference information either in this
book, or in the common book set, which includes the
RS/6000
Eserver
pSeries
Diagnostic Information for Multiple Bus Systems
and
PCI Adapter Placement
Reference
.
The Quick Entry MAP is a subset of the Entry MAP and helps to save time for some
types of problems.
The Problem Determination MAP provides a structured analysis method to get an error
code if one is not provided by the customer, or if diagnostics cannot be loaded.
The Power MAP deals with isolation of components to diagnose a power problem.
Power problems can be related to powering on and powering off the system, or power
failures that occur after power is turned on.
23
The Minimum Configuration MAP is used to locate defective components not found by
normal diagnostics or error-isolation methods. This MAP provides a systematic method
of isolation to the failing item or items.
Attention LED and Lightpath LEDs
The Attention and Lightpath LEDs provide a means to identify failing components in
your server. When a failing component is detected in your server, the Attention LED is
turned on. To further help you identify the failing component, go to the indicator panel
(see “Indicator Panel”) inside the server and check which LEDs are on.
Indicator Panel
The panel provides enough information to identify the area that needs attention. The
panel contains a group of amber LEDs that indicate which functional area of the system
is experiencing the fault (such as power, CPUs, memory, fans). If one of these LEDs is
on, the user or service representative is directed to the physical area of the server
where an additional LED on will be on, indicating the component that is responsible for
the current fault.

Component LEDs
In addition to the indicator panel or display, individual LEDs are located on or near the
failing components. The LEDs are either on the component itself or on the carrier of the
component (memory card, fan, memory module, CPU).
The LEDs are amber, except for the power supplies. For the power supplies, two green
LEDs (ac power good and dc power good) indicate the fault condition for the power
supply.
Resetting the LEDs
To reset the LEDs:
1. Replace the failing component with the new component.
2. Log in as root user.
3. At the command line, type diag.
4. Select Task Selection.
5. Select Log Repair Action.
6. Select the device that was repaired. (If the device is not listed, select sysplanar0.)
Chapter 2. Diagnostic Overview 25
Checkpoints
The system uses various types of checkpoints, error codes, and SRNs, which are
referred to throughout this book (primarily in Chapter 4, “Checkpoints” on page 81,
Chapter 5, “Error Code to FRU Index” on page 109, Chapter 6, “Loading the System
Diagnostics” on page 175, and Chapter 10, “Parts Information” on page 293). These
codes may appear in the service processor boot progress log, the AIX error log, and the
operator panel display. Understanding the definition and relationships of these codes is
important to the service personnel who are installing or maintaining the system.
Codes that can appear on the operator panel or in error logs are as follows:
Checkpoints
Checkpoints display in the operator panel from the time ac power is connected
to the system until the AIX login prompt is displayed after a successful
operating system boot. These checkpoints have the following forms:
E000 - E075
These checkpoints display from the time ac power is connected to the
system until the OK prompt displays on the operator panel display.
During this time, the service processor performs self-test and NVRAM
initialization.
E0A0 - E0E1
When power on is initiated, the service processor starts built-in
self-test (BIST) on the central electronics complex (CEC). VPD data is
read.
E0E2 - E2xx
This range indicates that the system processor is in control and is
initializing system resources.
E3xx These codes indicate that the system processor is running memory
tests.
E1xx The system firmware attempts to boot from devices in the boot list.
Control is passed to AIX when E105 (normal mode boot) or E15B
(service mode boot) displays on the operator panel display.
0xxx and 2xxx
0xxx codes are AIX checkpoints and configuration codes. Location
codes may also be shown on the operator panel display during this
time.
Error Codes
If a fault is detected, an 8-digit error code is displayed in the operator panel
display. A location code may be displayed at the same time on the second line
of the display.
Checkpoints can become error codes if the system fails to advance past the
point at which the code was presented.
For a list of checkpoints, see Chapter 4, “Checkpoints” on page 81. Each entry
provides a description of the event and the recommended action if the system
fails to advance.
26 Service Guide
SRNs Service request numbers, in the form xxx-xxx, may also be displayed on the
operator panel display and be noted in the AIX error log.
SRNs are listed in the
Diagnostic Information for Multiple Bus Systems
.
FRU Isolation
For a list of error codes and recommended actions for each code, see Chapter 5, “Error
Code to FRU Index” on page 109. These actions can refer to Chapter 10, “Parts
Information” on page 293, Chapter 3, “Maintenance Analysis Procedures (MAPs)” on
page 31, or provide informational message and directions. If a replacement part is
indicated, direct reference is made to the part name. The respective AIX and physical
location codes are listed for each occurrence as required. For a list of locations codes,
see “Location Codes” on page 11.
To look up part numbers and view component diagrams, see Chapter 10, “Parts
Information” on page 293. The beginning of that chapter provides a parts index with the
predominant field replaceable units (FRUs) listed by name. The remainder of the
chapter provides illustrations of the various assemblies and components that make up
the system.
Electronic Service Agent for the RS/6000
Service support for the system can be enhanced through the use of the application
program, Electronic Service Agent for the RS/6000. This application provides a number
of advantages for the customer, including automatic error reporting and analysis without
customer intervention. The Electronic Service Agent kit ships with the system and
includes the following:
v Electronic Service Agent for the RS/6000 program on CD-ROM
v The manual
Electronic Service Agent for the RS/6000 User’s Guide
.
If the manual is not included, it can be downloaded from the following Web site:
ftp://ftp.software.ibm.com/aix/.
Using the Service Processor and Electronic Service Agent Features
The service processor and Electronic Service Agent features protect users against
unnecessary system downtime by advising support personnel (both internal and
external) of any unexpected changes in the system environment. In combination, the
two features provide a flexible solution to automated system maintenance.
Service Processor
The service processor runs on its own power boundary and continually monitors
hardware attributes, the AIX operating system, and the environmental conditions within
the system. Any system failure which prevents the system from coming back to an
operational state (a fully functional AIX operating system) is reported by the service
processor. The service processor is controlled by firmware and does not require the AIX
Chapter 2. Diagnostic Overview 27
operating system to be operational to perform its tasks. If any system failures are
detected, the service processor can take predetermined corrective actions. The
methods of corrective actions are:
v Surveillance
v Call home
v AIX operating system monitoring
Surveillance is a function in which the service processor monitors the system through
heartbeat communication with the system firmware. The
heartbeat
is a periodic signal
that the firmware can monitor. During system startup, the firmware surveillance monitor
is automatically enabled to check for heartbeats from the firmware. If a heartbeat is not
detected within a default period, the service processor cycles the system power and
attempts to restart until the system either restarts successfully, or a predetermined retry
threshold is reached. In the event the service processor is unsuccessful in bringing the
system online (or in the event that the user asked to be alerted to any service
processor-assisted restarts), the system can call home to report the error.
The call home function can be initialized to call either a service center telephone
number, a customer administration center, or a digital pager telephone number. The
service processor can be configured to stop at the first successful call to any of the
numbers listed, or can be configured to call every number provided. If connected to the
service center, the service processor transmits the relevant system information (the
system’s serial number and model type) and service request number (SRN). If
connected to a digital pager service, the service processor inputs a customer voice
telephone number defined by the customer. An established sequence of digits or the
telephone number to a phone near the failed system could be used to signal a system
administrator to a potential system failure.
During normal operations, the service processor can also be configured to monitor the
AIX operating system. If AIX does not respond to the service processor heartbeat, the
service processor assumes the operating system is hung. The service processor can
automatically initiate a restart and, if enabled, initiate the call home function to alert the
appropriate people to the system hang. Enabling operating system surveillance also
enables AIX to detect any service processor failures and report those failures to the
Electronic Service Agent application.
Unlike the Electronic Service Agent, the service processor cannot be configured in a
client/server environment where one system can be used to manage all dial-out
functionally for a set of systems.
Prior to installing the Electronic Service Agent feature, ensure that you have the latest
level of system firmware. You also need a properly configured modem. For more
information on configuring a modem, see Appendix D, “Modem Configurations” on
page 313.
Electronic Service Agent
The Electronic Service Agent is a software extension to the AIX operating system that
monitors the system while the AIX operating system is running. The Electronic Service
28 Service Guide
Agent monitors and analyzes all recoverable system failures, and, if needed, can
automatically place a service call to a service center (without user intervention).
The service center receives the machine type/serial number, host name, SRN, and a
problem description. The service center analyzes the problem report and, if warranted,
dispatches a service person to the customer site. The service center also determines if
any hardware components need to be ordered prior to the service person’s arrival.
The Electronic Service Agent code also gives the user the option to establish a single
system as the problem reporting server. A single system, accessible over the user
network, can be used as the central server for all the other systems on the local area
network (LAN) that are running the Electronic Service Agent application. If the
Electronic Service Agent application on a remote client decides a service request needs
to be placed, the client forwards the information to the Electronic Service Agent server,
which dials the service center telephone number from its locally attached modem. In
this scenario, the user only needs to maintain a single analog line for providing call-out
capabilities for a large set of servers.
When used in a Scalable Parallel (SP) environment, a client/server type implementation
is configured. The Electronic Service Agent client code runs on each of the SP nodes.
The server component runs on the control workstation. In the event of any system
failures, the relevant information is transmitted to the control workstation through the
integrated Ethernet. Once alerted to the system failure, the control workstation initiates
actions to prepare and send the service request.
A modem is required for enabling automated problem reporting to the IBM service
center. Configuration files for several types of modems are included as part of the
Electronic Service Agent package. Refer to Appendix D, “Modem Configurations” on
page 313 for more information on configuring your modem.

Chapter 3. Maintenance Analysis Procedures (MAPs)
This chapter contains Maintenance Analysis Procedures (MAPs) for the system.
Notes:
1. If you replace a FRU, go to ″MAP 0410: Repair Checkout″ in the
RS/6000
Eserver
pSeries Diagnostic Information for Multiple Bus Systems
to verify correct system
operation.
2. When possible, run online diagnostics in service mode. Online diagnostics perform
additional functions compared to standalone diagnostics. This ensures that the error
state of the system that has been captured in nonvolatile random access memory
(NVRAM) is available for your use in fixing the problem. The AIX error log and SMIT
are only available when diagnostics are run from the hard drive.
3. If more than eight digits are displayed in the operator panel, use only the first eight
digits to find the error in the tables. The digits that display beyond the first eight
digits are location codes that can assist you in diagnosing the problem. See
“Location Codes” on page 11.
4. Licensed programs frequently rely on system information stored on the vital product
data (VPD) on the operator panel control assembly. If the MAPs indicate that the
operator panel should be replaced, update the VPD as described in “System Vital
Product Data (VPD) Update Procedure” on page 278.
5. If a network adapter or the system board is replaced, the network administrator
must be notified so that the client IP addresses used by the server can be changed.
In addition, the operating system configuration of the network controller might need
to be changed in order to enable system startup. Also check to ensure that any
client or server that addresses this system is updated.
6. If you are not able to isolate the problem, try loading standalone diagnostics from
the CD-ROM or NIM.

DANGER
An electrical outlet that is not correctly wired could place hazardous voltage
on metal parts of the system or the devices that attach to the system. It is the
responsibility of the customer to ensure that the outlet is correctly wired and
grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables for
the system unit and all attached devices are unplugged.
When adding or removing any additional devices to or from the system,
ensure that the power cables for those devices are unplugged before the
signal cables are connected. If possible, disconnect all power cables from the
existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to
prevent a possible shock from touching two surfaces with different electrical
potentials.
During an electrical storm, do not connect cables for display stations, printers,

MAP 1540: Minimum Configuration
Notes:
1. Be sure to unplug the power cords before removing or installing processor card(s),
the memory card, or the system board to avoid damage to it.
2. This MAP assumes that a CD-ROM drive is installed and connected to the
integrated SCSI or IDE adapter, and a diagnostic CD-ROM is available.
3. If a power-on password or privileged-access password is installed, you are
prompted to enter the password before the diagnostic CD-ROM can load.
4. The term ″POST indicators″ refers to the icons (graphic display) or device
mnemonics (ASCII terminal) that appear during the power-on self-test (POST).
5. The service processor might have recorded one or more symptoms in its error log.
It is a good idea to examine that error log before proceeding (see “System
Information Menu” on page 191).
6. The service processor might have been set by the user to monitor server operations
and to attempt recoveries. You might want to disable these actions while you
diagnose and service the system. If you disable them, make notes of their current
settings so that you can restore them before you leave. The following settings may
be of interest to you.
Surveillance From the Service Processor Setup Menu, go to
the OS Surveillance Setup Menu and disable
surveillance.
Unattended Start Mode From the System Power Control Menu, disable
unattended start mode.
Reboot Policy From the System Power Control Menu, go to
the Reboot/Restart Policy Setup Menu and set:
a. Number of reboot attempts to 0 (zero)
b. Use OS-Defined restart policy to No

Purpose of this MAP
This MAP is used to locate defective FRUs not found by normal diagnostics. For this
procedure, diagnostics are run on a minimally configured system. If a failure is detected
on the minimally configured system, the remaining FRUs are exchanged one at a time
until the failing FRU is identified. If a failure is not detected, FRUs are added back until
the failure occurs. The failure is then isolated to the failing FRU.
When directed to exchange a FRU that is common to a FRU removed to create a
minimum configuration system, use one of the removed FRUs instead of a new FRU.
For example, if the system contains 16 memory modules and you are directed to
remove 14 of them to create a minimun configuration system, then use one of the
removed memory modules when exchanging the FRU. Once the failing FRU is isolated,
replace it with a new one.
Step 1540-1
1. Insert the diagnostic CD-ROM into the CD-ROM drive.
Note: If you cannot insert the diagnostic CD-ROM, go to “Step 1540-2” on page 61.
2. Ensure that the diagnostics and the operating system are shut down.
3. Turn off the power.
4. Turn on the power.
5. When the keyboard indicator is displayed (the word keyboard on an ASCII terminal
or the keyboard icon on a graphical display), press the F5 key on the directly
attached keyboard or the number 5 key on an ASCII terminal.

Checkpoints let users and service personnel know what the server is doing, with some
detail, while it initializes. These checkpoints are not intended to be error indicators, but
in some cases, a server could hang at one of the checkpoints without displaying an
8-character error code. It is for these hang conditions, only, that any action should be
taken regarding checkpoints. The most appropriate action is included with each
checkpoint.
Before taking actions listed with a checkpoint, it is a good idea to look for more
appropriate symptoms in the service processor error log. See “System Information
Menu” on page 191. To access the System Information Menu, refer to “Privileged User
