Important information about replacing RoHS compliant FRUs

RoHS, The Restriction of Hazardous Substances in Electrical and Electronic
Equipment Directive (2002/95/EC) is a European Union legal requirement
affecting the global electronics industry. RoHS requirements must be
implemented on Lenovo products placed on the market and sold in the
European Union after June 2006. Products on the market before June 2006
are not required to have RoHS compliant parts. If the parts are not compliant
originally, replacement parts can also be noncompliant, but in all cases, if the
parts are compliant, the replacement parts must also be compliant.

Note: RoHS and non-RoHS FRU part numbers with the same fit and function are

identified with unique FRU part numbers.

Lenovo plans to transition to RoHS compliance well before the implementation date
and expects its suppliers to be ready to support Lenovo’s requirements and
schedule in the EU. Products sold in 2005, will contain some RoHS compliant
FRUs. The following statement pertains to these products and any product Lenovo
produces containing RoHS compliant parts.

RoHS compliant ThinkCentre parts have unique FRU part numbers. Before or after
June, 2006, failed RoHS compliant parts must always be replaced using RoHS
compliant FRUs, so only the FRUs identified as compliant in the system HMM or
direct substitutions for those FRUs can be used.

Products marketed before June 2006 Products marketed after June 2006

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
a Lenovo product that you are working on. Each Lenovo 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-Lenovo alterations or attachment of non-Lenovo 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 capacitor.
v Mechanical hazards, such as loose or missing hardware.

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

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

4. Remove the cover.

5. Check for any obvious non-Lenovo alterations. Use good judgment as to the

safety of any non-Lenovo 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.

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.

6 ThinkServer TD200x Types 3719, 3821, 3822, and 3823: Hardware Maintenance Manual

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 you use 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.

v Use extreme care when you measure high voltages.
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.

14 ThinkServer TD200x Types 3719, 3821, 3822, and 3823: Hardware Maintenance Manual

Chapter 3. General information

This chapter provides general information that applies to all machine types
supported by this publication.

Features and technologies

The TD200x server offers the following features and technologies:

v UEFI-compliant server firmware

The server firmware offers several features, including Unified Extensible
Firmware Interface (UEFI) 2.1 compliance, enhanced RAS capabilities, and BIOS
compatibility support. UEFI replaces the basic input/output system (BIOS) and
defines a standard interface between the operating system, platform firmware,
and external devices. UEFI-compliant servers are capable of starting
UEFI-compliant operating systems, BIOS-based operating systems, and
BIOS-based adapters as well as UEFI-compliant adapters.

Note: The server does not support DOS.

v Integrated Management Module

The integrated management module (IMM) combines service processor
functions, video controller, and remote presence function in a single chip. The
IMM provides advanced service-processor control, monitoring, and alerting
function. If an environmental condition exceeds a threshold or if a system
component fails, the IMM lights LEDs to help you diagnose the problem, records
the error in the event log, and alerts you to the problem. The IMM also provides
a virtual presence capability for remote server management capabilities. The IMM
provides remote server management through industry-standard interfaces:

– Intelligent Platform Management Interface (IPMI) version 2.0
– Simple Network Management Protocol (SNMP) version 3
– Common Information Model (CIM)
– Web browser

v Remote presence capability and blue-screen capture

The remote presence feature provides the following functions:
– Remotely viewing video with graphics resolutions up to 1600 x 1200 at 85 Hz,

regardless of the system state

– Remotely accessing the server, using the keyboard and mouse from a remote

client

– Mapping the CD or DVD drive, diskette drive, and USB flash drive on a

remote client, and mapping ISO and diskette image files as virtual drives that
are available for use by the server

– Uploading a diskette image to the IMM memory and mapping it to the server

as a virtual drive

The blue-screen capture feature captures the video display contents before the
IMM restarts the server when the IMM detects an operating-system hang
condition. A system administrator can use the blue-screen capture to assist in
determining the cause of the hang condition.

v Preboot diagnostics programs

The preboot diagnostics programs are stored on the integrated USB memory. It
collects and analyzes system information to aid in diagnosing server problems.
The diagnostics programs collect the following information about the server:

© Lenovo 2009. Portions © IBM Corp. 2009. 15

– System configuration
– Network interfaces and settings
– Installed hardware
– EasyLED diagnostics status
– Service processor status and configuration
– Vital product data, firmware, and UEFI (formerly BIOS) configuration
– Hard disk drive health
– RAID controller configuration
– Event logs for service processors
The diagnostic programs create a merged log that includes events from all

collected logs. The information is collected into a file that you can send to
Lenovo service and support. Additionally, you can view the information locally
through a generated text report file. You can also copy the log to a removable
media and view the log from a Web browser.

For additional information about preboot diagnostics, see “Running the diagnostic
programs” on page 90.

v EasyStartup DVD

The ThinkServer EasyStartup program guides you through the configuration of
the hardware, the RAID controller, and the installation of the operating system
and device drivers.

v EasyManage DVD

The ThinkServer EasyManage program helps you manage and administer your
servers and clients through remote problem notification as well as monitoring and
alerting.

v Integrated network support

The server comes with one integrated Broadcom 5709C series Gigabit Ethernet
controller, which supports connection to a 10 Mbps, 100 Mbps, or 1000 Mbps
network. For more information, see “Enabling the Broadcom Gigabit Ethernet
Utility program” on page 266.

v Intelligent Platform Management Interface (IPMI) 2.0

IPMI 2.0 support providing secure remote power-on/power-off and several
standard alerts for components such as fans, voltage, and temperature.

v Large data-storage capacity and hot-swap capability

The server supports up to eight or 16 (depending on your model) 2.5-inch
hot-swap hard disk drives in the hot-swap bays. With the hot-swap feature, you
can add, remove, or replace hard disk drives without turning off the server.

v Large system-memory capacity

The server supports up to 64 GB of system memory. The memory controller
supports error correcting code (ECC) for up to 16 single-sided industry-standard
third-generation double-data-rate 3 (DDR3) 800, 1066, and 1333, 240-pin,
registered, synchronous dynamic random access memory (SDRAM) dual inline
memory modules (DIMMs).

v EasyLED diagnostics

EasyLED diagnostics provides LEDs to help you diagnose problems. For more
information, see “EasyLED diagnostics panel” on page 129.

v Memory mirroring

Memory mirroring improves the availability of memory by writing information to
the main memory and redundant locations in a mirrored pair of DIMMs.

The server has five slots for PCI Express x8 adapters. Three of these slots
accept x8 adapters, but the adapters will operate as x4 adapters.

v PCI Express x16 adapter capabilities

The server has one slot for PCI Express x16 adapter, which will operate as an x8
adapter.

v Redundant cooling and power capabilities

The server supports up to two 920-watt hot-swap power supplies. If the server
came with only one power supply, you can install an additional power supply with
three redundant hot-swap cooling fans to add redundant power and cooling
capabilities. If the maximum load on the server is less than 920 watts and a
problem occurs with one of the power supplies, the other power supply can meet
the power requirements. The redundant cooling of the fans enables continued
operation if one of the fans fails.

v RAID support

The server supports an internal RAID SAS Controller, which is required for you to
use the hot-swap hard disk drives and to create redundant array of independent
disks (RAID) configurations.

v Symmetric multiprocessing (SMP)

®

The server supports up to two Intel

Xeon®quad-core microprocessors. If the
server comes with only one microprocessor, you can install an additional
microprocessor to enhance performance and provide SMP capability.

v Systems-management capabilities

The server contains an Integrated Management Module (IMM) which enables you
to manage the functions of the server locally and remotely and provides remote
presence and blue-screen capture capability. The IMM also provides system
monitoring and event recording.

v TCP/IP offload engine (TOE) support

The Ethernet controllers in the server support TOE, which is a technology that
offloads the TCP/IP flow from the microprocessors and I/O subsystem to increase
the speed of the TCP/IP flow. When an operating system that supports TOE is
running on the server and TOE is enabled, the server supports TOE operation.
See the operating-system documentation for information about enabling TOE.

Chapter 4. General Checkout

You can solve many problems without outside assistance by following the
troubleshooting procedures in this Hardware Maintenance Manual and on the
Lenovo Web site. This document describes the diagnostic tests that you can
perform, troubleshooting procedures, and explanations of error messages and error
codes. The documentation that comes with your operating system and software
also contains troubleshooting information.

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 you perform 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 multiple error codes or EasyLED diagnostics LEDs indicate a
microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 69 for
information about diagnosing microprocessor problems.

v Before you run 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.

© Lenovo 2009. Portions © IBM Corp. 2009. 21

v If the server is halted and a POST error code is displayed, see “POST error

codes” on page 30. If the server is halted and no error message is displayed,
see “Troubleshooting tables” on page 64 and “Solving undetermined problems”
on page 124.

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

page 123 and “Power-supply LEDs” on page 88.

v For intermittent problems, check the system-event log; see “Event logs” on page

27, “System-event log” on page 38, and “Diagnostic programs, messages, and
error codes” on page 90.

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.

g. Check the system-error LED on the operator information panel (see

Chapter 6, “Locating Server Controls and connectors,” on page 127). If it is

flashing, check the EasyLED diagnostics LEDs (see “EasyLED diagnostics”

on page 76).
h. Check for the following results:

v Successful completion of POST

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

operating-system desktop

3. Are there readable instructions on the main menu?
v No: Find the failure symptom in “Troubleshooting tables” on page 64; if

necessary, see “Solving undetermined problems” on page 124.

v Yes: Run the diagnostic programs (see “Running the diagnostic programs” on

page 90).
– If you receive an error, see “Diagnostic messages” on page 91.
– If the diagnostic programs were completed successfully and you still

suspect a problem, see “Solving undetermined problems” on page 124.

Diagnosing a problem

Before you contact Lenovo or an approved warranty service provider, follow these
procedures in the order in which they are presented to diagnose a problem with
your server:

1. Determine what has changed.

22 ThinkServer TD200x Types 3719, 3821, 3822, and 3823: Hardware Maintenance Manual

Determine whether any of the following items were added, removed, replaced,
or updated before the problem occurred:

v Lenovo ThinkServer Server Firmware (server firmware)
v Device drivers
v Firmware
v Hardware components
v Software

If possible, return the server to the condition it was in before the problem
occurred.

2. Collect data.
Thorough data collection is necessary for diagnosing hardware and software

problems.
a. Document error codes and system-board LEDs.

v System error codes: See “Viewing the test log” on page 91 for

information about error codes.

v Software or operating-system error codes: See the documentation for

the software or operating system for information about a specific error
code. See the manufacturer's Web site for documentation.

v EasyLED diagnostics LEDs: See “EasyLED diagnostics” on page 76 for

information about EasyLED diagnostics LEDs that are lit.

v System-board LEDs: See “System-board LEDs” on page 135 for

information about system-board LEDs that are lit.

“EasyLED diagnostics” on page 76

b. Collect system data.

Run Dynamic System Analysis (DSA) to collect information about the
hardware, firmware, software, and operating system. Have this information
available when you contact Lenovo or an approved warranty service
provider. For instructions for running the DSA program, see “Running the
diagnostic programs” on page 90.

If you have to download the latest version of DSA , complete the following
steps.

Note: Changes are made periodically to the Lenovo Web site. The actual
procedure might vary slightly from what is described in this document.

1) Go to: http://www.lenovo.com/support.

2) Enter your product number (machine type and model number) or select
Servers and Storage from the Select your product list.

3) Select Servers and Storage from the Brand list.

4) From Family list, select ThinkServer TD200x, and click Continue.

5) Click Downloads and drivers and look at the list for the Preboot DSA
CD image.

3. Follow the problem-resolution procedures.
The four problem-resolution procedures are presented in the order in which they

are most likely to solve your problem. Follow these procedures in the order in
which they are presented:

a. Check for and apply code updates.

Most problems that appear to be caused by faulty hardware are actually
caused by Lenovo ThinkServer Server Firmware (server firmware), system
firmware, device firmware, or device drivers that are not at the latest levels.

Chapter 4. General Checkout 23

Important: Some cluster solutions require specific code levels or
coordinated code updates. If the device is part of a cluster solution, verify
that the latest level of code is supported for the cluster solution before you
update the code.

1) Determine the existing code levels.
In DSA, click Firmware/VPD to view system firmware levels, or click

Software to view operating-system levels.

2) Download and install updates of code that is not at the latest level.
To display a list of available updates for your server, complete the

following steps.

Note: Changes are made periodically to the Lenovo Web site. The
actual procedure might vary slightly from what is described in this

c) Select Servers and Storage from the Brand list.
d) From Family list, select ThinkServer TD200x, and click Continue.
e) Click System TD200x to display the list of downloadable files for the

server.

b. Check for and correct an incorrect configuration.

If the server is incorrectly configured, a system function can fail to work
when you enable it; if you make an incorrect change to the server
configuration, a system function that has been enabled can stop working.

1) Make sure that all installed hardware and software are supported.
See http://www.lenovo.com/thinkserver to verify that the server supports

the installed operating system, optional devices, and software levels. If
any hardware or software component is not supported, uninstall it to
determine whether it is causing the problem. You must remove
nonsupported hardware before you contact Lenovo or an approved
warranty service provider for support.

2) Make sure that the server, operating system, and software are

installed and configured correctly.

Many configuration problems are caused by loose power or signal
cables or incorrectly seated adapters. You might be able to solve the
problem by turning off the server, reconnecting cables, reseating
adapters, and turning the server back on. For information about
performing the checkout procedure, see “Checkout procedure” on page

21.
If the problem is associated with a specific function (for example, if a

RAID hard disk drive is marked offline in the RAID array), see the
documentation for the associated controller and management or
controlling software to verify that the controller is correctly configured.

Problem determination information is available for many devices such as
RAID and network adapters.

For problems with operating systems or Lenovo software or devices,

unpredictable results. Most hardware failures are reported as error codes in
a system or operating-system log. For more information, see
“Troubleshooting tables” on page 64 and Chapter 7, “Installing optional
devices and replacing customer replaceable units,” on page 149. Hardware
errors are also indicated by EasyLED diagnostics LEDs.

A single problem might cause multiple symptoms. Follow the troubleshooting
procedure for the most obvious symptom. If that procedure does not
diagnose the problem, use the procedure for another symptom, if possible.

If the problem remains, contact Lenovo or an approved warranty service
provider for assistance with additional problem determination and possible
hardware replacement. Be prepared to provide information about any error
codes and collected data.

Undocumented problems

If you have completed the diagnostic procedure and the problem remains, the
problem might not have been previously identified by Lenovo. After you have
verified that all code is at the latest level, all hardware and software configurations
are valid, and no EasyLED diagnostics LEDs or log entries indicate a hardware
component failure, contact Lenovo or an approved warranty service provider for
assistance. Be prepared to provide information about any error codes and collected
data and the problem determination procedures that you have used.

Chapter 5. Diagnostics

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

If you cannot diagnose and correct a problem by using the information in this
chapter, see Appendix A, “Getting help and technical assistance,” on page 275 for
more information.

Diagnostic tools

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

v POST error messages

The power-on self-test (POST) generates messages to indicate successful test
completion or the detection of a problem. See “POST error codes” on page 30
for more information.

v Event logs

For information about the POST event log, the system-event log, the integrated
management module (IMM) event log, and the DSA log, see “Event logs” and
“System-event log” on page 38.

v Troubleshooting tables

These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 64.

v EasyLED diagnostics

|
|

Use the EasyLED diagnostics to diagnose system errors quickly. See “EasyLED
diagnostics” on page 76 for more information.

v Diagnostic programs, messages, and error codes

The diagnostic programs are the primary method of testing the major
components of the server. See “Diagnostic programs, messages, and error
codes” on page 90 for more information.

Event logs

Error codes and messages are displayed in the following types of event logs:
v POST event log: This log contains the three most recent error codes and

messages that were generated during POST. You can view the POST event log
through the Setup utility.

v System-event log: This log contains all IMM, POST, and system management

interrupt (SMI) events. You can view the system-event log through the Setup
utility and through the Dynamic System Analysis (DSA) program (as the IPMI
event log).

The system-event log is limited in size. When it is full, new entries will not
overwrite existing entries; therefore, you must periodically save and then clear
the system-event log through the Setup utility when the IMM logs an event that
indicates that the log is more than 75% full. When you are troubleshooting, you
might have to save and then clear the system-event log to make the most recent
events available for analysis.

Messages are listed on the left side of the screen, and details about the selected
message are displayed on the right side of the screen. To move from one entry
to the next, use the Up Arrow (↑) and Down Arrow (↓) keys.

© Lenovo 2009. Portions © IBM Corp. 2009. 27

Some IMM sensors cause assertion events to be logged when their setpoints are
reached. When a setpoint condition no longer exists, a corresponding
deassertion event is logged. However, not all events are assertion-type events.

v Integrated management module (IMM) event log: This log contains a filtered

subset of all IMM, POST, and system management interrupt (SMI) events. You
can view the IMM event log through the IMM Web interface and through the
Dynamic System Analysis (DSA) program (as the ASM event log).

v DSA log: This log is generated by the Dynamic System Analysis (DSA) program,

and it is a chronologically ordered merge of the system-event log (as the IPMI
event log), the IMM event log (as the ASM event log), and the operating-system
event logs. You can view the DSA log through the DSA program.

Viewing event logs through the Setup utility

To view the POST event log or system-event log, complete the following steps:

1. Turn on the server.

2. When the prompt <F1> Setup is displayed, press F1. If you have set both a
power-on password and an administrator password, you must type the
administrator password to view the event logs.

3. Select System Event Logs and use one of the following procedures:

v To view the POST event log, select POST Event Viewer.
v To view the system-event log, select System Event Log.

Viewing event logs without restarting the server

If the server is not hung, methods are available for you to view one or more event
logs without having to restart the server.

|
|
|
|

You can use the DSA Preboot to view the system event log (as the IPMI event log),
the IMM event log (as the ASM event log), or the merged DSA log. You must restart
the server to use DSA Preboot to view those logs. To install a DSA Preboot CD
image, complete the following steps:

Note: Changes are made periodically to the Lenovo Web site. The actual
procedure might vary slightly from what is described in this document.

1. Go to: http://www.lenovo.com/support.

2. Enter your product number (machine type and model number) or select Servers
and Storage from the Select your product list.

3. Select Servers and Storage from the Brand list.

4. From Family list, select ThinkServer TD200x, and click Continue.

5. Click Downloads and drivers and look at the list for the Preboot DSA CD
image.

You can view the IMM event log through the Event Log link in the integrated
management module (IMM) Web interface.

The following table describes the methods that you can use to view the event logs,
depending on the condition of the server. The first two conditions generally do not
require that you restart the server.

POST error codes

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
you are prompted, for POST to run.

If POST is completed without detecting any problems, the server startup is
completed.

If POST detects a problem, an error message is sent to the POST event log.

The following table describes the POST error codes and suggested actions to
correct the detected problems. These errors can appear as severe, warning, or
informational.

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

is solved.

EasyLED diagnostics

|

EasyLED diagnostics is a system of LEDs on various external and internal
components of the server. When an error occurs, LEDs are lit throughout the
server. By viewing the LEDs in a particular order, you can often identify the source
of the error.

When LEDs are lit to indicate an error, they remain lit when the server is turned off,
provided that the server is still connected to power and the power supply is
operating correctly.

Before you work inside the server to view the EasyLED diagnostics LEDs, read the
safety information that begins on page 5.

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

1. Look at the operator information panel LEDs on the front of the server.
v If an operator information panel LED is lit, it indicates that information about a

suboptimal condition in the server is available in the system-event log.

v If the system-error LED is lit, it indicates that an error has occurred; go to

step 2 on page 77.

The following illustration shows the operator information panel LEDs that are
visible through the bezel.

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 messages” on page 91.

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 the prompt Press F2 for Dynamic System Analysis (DSA) is displayed,
press F2.

Note: The DSA Preboot diagnostic program might appear to be unresponsive
for an unusual length of time when you start the program. This is normal
operation while the program loads.

4. Optionally, select Quit to DSA to exit from the stand-alone memory diagnostic
program.

Note: After you exit from the stand-alone memory diagnostic environment, you
must restart the server to access the stand-alone memory diagnostic
environment again.

5. Select gui to display the graphical user interface, or select cmd to display the
DSA interactive menu.

6. Follow the instructions on the screen to select the diagnostic test to run.

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 multiple error codes or EasyLED diagnostics LEDs indicate a
microprocessor error, the error might be in a microprocessor or in a microprocessor
socket. See “Microprocessor problems” on page 69 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.

Diagnostic text messages

Diagnostic text messages are displayed while the tests are running. A diagnostic
text message contains one of the following results:

Passed: The test was completed without any errors.

Failed: The test detected an error.

90 ThinkServer TD200x Types 3719, 3821, 3822, and 3823: Hardware Maintenance Manual

User Aborted: You stopped the test before it was completed.

Not Applicable: You attempted to test a device that is not present in the server.

Aborted: The test could not proceed because of the server configuration.

Warning: The test could not be run. There was no failure of the hardware that was

being tested, but there might be a hardware failure elsewhere, or another problem
prevented the test from running; for example, there might be a configuration
problem, or the hardware might be missing or is not being recognized.

The result is followed by an error code or other additional information about the
error.

Viewing the test log

To view the DSA log when the tests are completed, select Utility from the top of the
screen and then select View Test Log. To view a detailed test log, press Tab while
you view the DSA log. The DSA log data is maintained only while you are running
the diagnostic programs. When you exit from the diagnostic programs, the DSA log
is cleared.

To save the DSA log to a file on a diskette or to the hard disk, click Save Log on
the diagnostic programs screen and specify a location and name for the saved log
file.

Notes:

1. To create and use a diskette, you must add an optional external diskette drive to
the server.

2. To save the test log to a diskette, you must use a diskette that you have
formatted yourself; this function does not work with preformatted diskettes. If the
diskette has sufficient space for the test log, the diskette can contain other data.

Diagnostic messages

generate and suggested actions to correct the detected problems. Follow the
suggested actions in the order in which they are listed in the column.
