Guidelines for trained service technicians
This section contains information for trained service technicians.
Inspecting for unsafe conditions
Use the information in this section to help you identify potential unsafe conditions in
an IBM product on which you are working. Each IBM product, as it was designed
and manufactured, has required safety items to protect users and service
technicians from injury. The information in this section addresses only those items.
Use good judgment to identify potential unsafe conditions that might be caused by
non-IBM alterations or attachment of non-IBM features or options that are not
addressed in this section. If you identify an unsafe condition, you must determine
how serious the hazard is and whether you must correct the problem before you
work on the product.
Consider the following conditions and the safety hazards that they present:
v Electrical hazards, especially primary power. Primary voltage on the frame can
cause serious or fatal electrical shock.
v Explosive hazards, such as a damaged CRT face or a bulging capacitor.
v Mechanical hazards, such as loose or missing hardware.
inspect the product for potential unsafe conditions, complete the following steps:
To
1. Make sure that the power is off and the power cord is disconnected.
2. Make sure that the exterior cover is not damaged, loose, or broken, and
observe any sharp edges.
3. Check the power cord:
v Make sure that the third-wire ground connector is in good condition. Use a
meter to measure third-wire ground continuity for 0.1 ohm or less between
the external ground pin and the frame ground.
v Make sure that the power cord is the correct type, as specified in the
documentation for your BladeCenter unit type.
v Make sure that the insulation is not frayed or worn.
Remove the cover.
4.
5. Check for any obvious non-IBM alterations. Use good judgment as to the safety
of any non-IBM alterations.
6. Check inside the server for any obvious unsafe conditions, such as metal filings,
contamination, water or other liquid, or signs of fire or smoke damage.
7. Check for worn, frayed, or pinched cables.
8. Make sure that the power-supply cover fasteners (screws or rivets) have not
been removed or tampered with.
Guidelines for servicing electrical equipment
Observe the following guidelines when servicing electrical equipment:
v Check the area for electrical hazards such as moist floors, non-grounded power
extension cords, 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 current.
v Regularly inspect and maintain your electrical hand tools for safe operational
condition. Do not use worn or broken tools or testers.
viii BladeCenter HS21 Types 1885 and 8853: Problem Determination and Service Guide
Page 11
v Do not touch the reflective surface of a dental mirror to a live electrical circuit.
The surface is conductive and can cause personal injury or equipment damage if
it touches a live electrical circuit.
v Some rubber floor mats contain small conductive fibers to decrease electrostatic
discharge. Do not use this type of mat to protect yourself from electrical shock.
v Do not work alone under hazardous conditions or near equipment that has
hazardous voltages.
v Locate the emergency power-off (EPO) switch, disconnecting switch, or electrical
outlet so that you can turn off the power quickly in the event of an electrical
accident.
v Disconnect all power before you perform a mechanical inspection, work near
power supplies, or remove or install main units.
v Before you work on the equipment, disconnect the power cord. If you cannot
disconnect the power cord, have the customer power-off the wall box that
supplies power to the equipment and lock the wall box in the off position.
v Never assume that power has been disconnected from a circuit. Check it to
make sure that it has been disconnected.
v If you have to work on equipment that has exposed electrical circuits, observe
the following precautions:
– Make sure that another person who is familiar with the power-off controls is
near you and is available to turn off the power if necessary.
– When you are working with powered-on electrical equipment, use only one
hand. Keep the other hand in your pocket or behind your back to avoid
creating a complete circuit that could cause an electrical shock.
– When using a tester, set the controls correctly and use the approved probe
leads and accessories for that tester.
– Stand on a suitable rubber mat to insulate you from grounds such as metal
floor strips and equipment frames.
Use extreme care when measuring high voltages.
v
v To ensure proper grounding of components such as power supplies, pumps,
blowers, fans, and motor generators, do not service these components outside of
their normal operating locations.
v If an electrical accident occurs, use caution, turn off the power, and send another
person to get medical aid.
Safety statements
Important:
Each caution and danger statement in this documentation begins with a number.
This number is used to cross reference an English-language caution or danger
statement with translated versions of the caution or danger statement in the Safety
Information document.
For example, if a caution statement begins with a number 1, translations for that
caution statement appear in the Safety Information document under statement 1.
Be sure to read all caution and danger statements in this documentation before
performing the instructions. Read any additional safety information that comes with
your server or optional device before you install the device.

Power-on LED
Keyboard/video/mouse (KVM) select button: Press this button to associate the
shared BladeCenter unit keyboard port, video port, and mouse port with the blade
server. The LED on this button flashes while the request is being processed, and
then is lit when the ownership of the keyboard, video, and mouse has been
transferred to the blade server. It can take approximately 20 seconds to switch the
keyboard, video, and mouse control to the blade server.
Using a keyboard that is directly attached to the management-module, you can
press keyboard keys in the following sequence to switch KVM control between
blade servers:
NumLock NumLock blade_server_number Enter
Where blade_server_number is the two-digit number for the blade bay in which
the blade server is installed. A blade server that occupies more than one blade
bay is identified by the lowest bay number that it occupies.
If there is no response when you press the KVM select button, you can use the
management-module Web interface to determine whether local control has been
disabled on the blade server.
Note:
1. The operating system in the blade server must provide USB support for the
blade server to recognize and use the keyboard and mouse, even if the
keyboard and mouse have PS/2-style connectors.
2. If you install a supported Microsoft Windows operating system on the blade
server while it is not the current owner of the keyboard, video, and mouse, a
delay of up to 1 minute occurs the first time that you switch the keyboard, video,
and mouse to the blade server. All subsequent switching takes place in the
normal KVM switching time frame (up to 20 seconds).

Turning on the blade server
After you connect the blade server to power through the BladeCenter unit, the blade
server can start in any of the following ways:
v Yo u can press the power-control button on the front of the blade server (behind
the control panel door, see “Blade server controls and LEDs” on page 4) to start
the blade server.
Notes:
1. Wait until the power-on LED on the blade server flashes slowly before
pressing the power-control button. While the service processor in the
management module is initializing, the power-on LED does not flash, and the
power-control button on the blade server does not respond.
2. While the blade server is starting, the power-on LED on the front of the blade
server is lit. See “Blade server controls and LEDs” on page 4 for the
power-on LED states.
If a power failure occurs, the BladeCenter unit and then the blade server can
v
start automatically when power is restored, if the blade server is configured
through the management module to do so.
v Yo u can turn on the blade server remotely by using the management module.
v If the blade server is connected to power (the power-on LED is flashing slowly),
the operating system supports the Wake on LAN® feature, and the Wake on LAN
feature has not been disabled through the management module, the Wake on
LAN feature can turn on the blade server.
Turning off the blade server
When you turn off the blade server, it is still connected to power through the
BladeCenter unit. The blade server can respond to requests from the service
processor, such as a remote request to turn on the blade server. To remove all
power from the blade server, you must remove it from the BladeCenter unit.

Chapter 2. Configuration information and instructions
This chapter provides information about updating the firmware and using the
configuration utilities.
Firmware updates
IBM periodically makes BIOS, service processor (BMC), and diagnostic firmware
updates available for the blade server. Go to http://www.ibm.com/systems/support/
to download the latest firmware for the blade server. Install any updates, using the
instructions that are included with the downloaded file.
Important: To avoid problems and to maintain proper system performance, always
ensure that the blade server BIOS, service processor, and diagnostic firmware
levels are consistent for all blade servers of the same type within the BladeCenter
unit.
Using the Configuration/Setup Utility program
The Configuration/Setup Utility program is part of the BIOS. You can use it to:
v Change interrupt request (IRQ) settings
v Change the startup drive sequence
v Configure serial-port assignments
v Enable USB keyboard and mouse support
v Resolve configuration conflicts
v Set the date and time
v Set passwords and security settings
start the Configuration/Setup Utility program, complete the following steps:
To
1. Turn on the server.
2. When the message Press F1 for Configuration/Setup appears, press F1. If
an administrator password has been set, you must type the administrator
password to access the full Configuration/Setup Utility menu.
3. Follow the instructions on the screen.
Configuring the Gigabit Ethernet controllers
Two Ethernet controllers are integrated on the blade server system board. Each
controller provides a 1-Gbps full-duplex interface for connecting to one of the
Ethernet-compatible switch modules in I/O-module bays 1 and 2, which enables
simultaneous transmission and reception of data on the Ethernet local area network
(LAN). Each Ethernet controller on the system board is routed to a different switch
module in I/O module bay 1 or bay 2. See “Blade server Ethernet controller
enumeration” on page 12 for information about how to determine the routing from
Ethernet controller to I/O-module bay for your blade server.
You do not have to set any jumpers or configure the controllers for the blade server
operating system. However, you must install a device driver to enable the blade
server operating system to address the Ethernet controllers. For device drivers and
information about configuring the Ethernet controllers, see the Broadcom NetXtreme
© Copyright IBM Corp. 2007 11
Page 28
Gigabit Ethernet Software CD that comes with the blade server. To find updated
information about configuring the controllers, see http://www.ibm.com/systems/
support/
The Ethernet controllers support failover, which provides automatic redundancy for
the Ethernet controllers. Without failover, you can have only one Ethernet controller
from each server attached to each virtual LAN or subnet. With failover, you can
configure more than one Ethernet controller from each server to attach to the same
virtual LAN or subnet. Either one of the integrated Ethernet controllers can be
configured as the primary Ethernet controller. If you have configured the controllers
for failover and the primary link fails, the secondary controller takes over. When the
primary link is restored, the Ethernet traffic switches back to the primary Ethernet
controller. See your operating system device driver documentation for information
about configuring for failover.
Important: To support failover on the blade server Ethernet controllers, the Ethernet
switch modules in the BladeCenter unit must have identical configurations.
Blade server Ethernet controller enumeration
The enumeration of the Ethernet controllers in a blade server is operating-system
dependent. Through the operating-system settings, you can verify the Ethernet
controller designations that a blade server uses.
The routing of an Ethernet controller to a particular I/O-module bay depends on the
type of blade server. Yo u can verify which Ethernet controller is routed to which
I/O-module bay by using the following test:
1. Install only one Ethernet switch module or pass-thru module in I/O-module bay
1.
2. Make sure that the ports on the switch module or pass-thru module are enabled
(I/O Module Tasks → Management → Advanced Management in the
management-module Web interface).
3. Enable only one of the Ethernet controllers on the blade server. Note the
designation that the blade server operating system has for the controller.
4. Ping an external computer on the network that the switch module is connected
to. If you can ping the external computer, the Ethernet controller that you
enabled is associated with the switch module in I/O-module bay 1. The other
Ethernet controller in the blade server is associated with the switch module in
I/O-module bay 2.
If you have installed an expansion card in a blade server, communication from the
expansion card is routed to I/O-module bays 3 and 4, if these bays are supported
by your BladeCenter unit. You can verify which controller on the card is routed to
which I/O-module bay by performing the same test and using a controller on the
expansion card and a compatible switch module or pass-thru module in I/O-module
bay 3 or 4.

Configuring a SAS RAID
Note: Configuring a SAS redundant array of independent disks (RAID) array
applies only to a blade server in which two SAS hard disk drives are installed.
You can configure a SAS RAID array for your blade server. You can use two SAS
hard disk drives in the blade server to implement and manage a RAID level-0
(striping) or RAID level-1 (mirroring) array under an operating system that is listed
at http://www.ibm.com/servers/eserver/serverproven/compat/us/. For more
information, see the Installation and User’s Guide.
If an optional BladeCenter Storage Expansion Unit 3 is installed, you can use it to
control all of the SAS hard disk drives installed in the blade server. Yo u enable this
feature using the Configuration/Setup Utility program (see the Installation and
User’s Guide for information and instructions).
Important: Yo u must create the RAID array before you install the operating system
on the blade server.
You can use the LSI Logic Configuration Utility program to configure the SAS hard
disk drives and SAS controller. To start the LSI Logic Configuration Utility, complete
the following steps:
1. Turn on the blade server (make sure that the blade server is the owner of the
keyboard, video, and mouse) and watch the monitor screen.
2. When the message
Press Ctrl-C to start LSI Logic Configuration Utility
appears, press F1. If an administrator password has been set, you must type
the administrator password to access the full LSI Logic Configuration Utility
menu.
3. Follow the instructions on the screen to modify the SAS hard disk drive and
SAS controller settings.

Replaceable components are of three types:
v Tier 1 customer replaceable unit (CRU): Replacement of Tier 1 CRUs is your
responsibility. If IBM installs a Tier 1 CRU at your request, you will be charged for
the installation.
v Tier 2 customer replaceable unit: You may install a Tier 2 CRU yourself or
request IBM to install it, at no additional charge, under the type of warranty that
is designated for your server.
v Field replaceable unit (FRU): FRUs must be installed only by trained service
technicians.

whether a component is a Tier 1 CRU, Tier 2 CRU, or FRU.
For information about the terms of the warranty and getting service and assistance,
see the Warranty and Support Information document.
Installation guidelines
Before you install options, read the following information:
v Read the safety information that begins on page vii and the guidelines in
“Handling static-sensitive devices” on page 20. This information will help you
work safely.
v When you install your new blade server, take the opportunity to download and
apply the most recent firmware updates. This step will help to ensure that any
known issues are addressed and that your blade server is ready to function at
maximum levels of performance.
To download firmware updates for your blade server, complete the following
steps.
Note: Changes are made periodically to the IBM Web site. The actual procedure
might vary slightly from what is described in this document.
1. Go to http://www.ibm.com/systems/support/.
2. Under Product support, click BladeCenter.
3. Under Popular links, click Software and device drivers.
4. Click BladeCenter HS21 (8853, 1885) to display the matrix of downloadable
files for the blade server.
v Observe good housekeeping in the area where you are working. Place removed
covers and other parts in a safe place.
v Back up all important data before you make changes to disk drives.
v Before you remove a blade server from the BladeCenter unit, you must shut
down the operating system and turn off the blade server. Yo u do not have to shut
down the BladeCenter unit itself.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the blade server, open or close a latch, and so
on.
v Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on

Page 36
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.
v For a list of supported options for the blade server, see http://www.ibm.com/
servers/eserver/serverproven/compat/us/.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that the following
requirements are met:
v Each microprocessor socket always contains either a microprocessor heat-sink
filler or a microprocessor and heat sink. If the blade server has only one
microprocessor, it must be installed in microprocessor socket 1.
v Yo u do not operate the BladeCenter unit without a blade server, expansion unit,
or filler blade installed in each blade bay to ensure proper cooling. See the
documentation for your BladeCenter unit for additional information.
v The blade server battery must be operational. If the battery becomes defective,
replace it immediately.
Handling static-sensitive devices
Attention: Static electricity can damage the blade server and other electronic
devices. To avoid damage, keep static-sensitive devices in their static-protective
packages until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v When working on the BladeCenter T unit, use an electrostatic discharge (ESD)
wrist strap, especially when you will be handling modules, options, and blade
servers. To work properly, the wrist strap must have a good contact at both ends
(touching your skin at one end and firmly connected to the front or back of the
BladeCenter unit).
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in the static-protective package, touch it to an unpainted
metal part of the BladeCenter unit or any unpainted metal surface on any other
grounded rack component in the rack you are installing the device in for at least
2 seconds. This drains static electricity from the package and from your body.
v Remove the device from the package and install it directly into the blade server
without setting down the device. If it is necessary to set down the device, put it
back into the static-protective package. Do not place the device on the blade
server cover or on a metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.
Returning a device or component
If you are instructed to return a device or component, follow all packaging
instructions, and use any packaging materials for shipping that are supplied to you.

Removing and replacing FRUs
FRUs must be installed only by trained service technicians.
The illustrations in this document might differ slightly from your hardware.
Removing a microprocessor and heat sink
Read the following important guidelines before removing a microprocessor that is
not faulty (for example, when you are replacing the system board assembly).
If you are not replacing a defective heat sink or microprocessor, the thermal
material on the heat sink and microprocessor will remain effective if you complete
the following steps:
1. Carefully handle the heat sink and microprocessor when removing or installing
these components. Do not touch the thermal material or otherwise allow it to
become contaminated.
2. In a dual-microprocessor blade server, the microprocessor and the heat sink are
a matched set. First transfer the heat sink and microprocessor from one socket
to the new system board; then, transfer the other heat sink and microprocessor.
(This will ensure that the thermal material remains evenly distributed between
each heat sink and microprocessor.)
Notes:
v The heat-sink FRU is packaged with the thermal material applied to the
underside. This thermal material is not available as a separate FRU. The heat
sink must be replaced when new thermal material is required, such as when a
defective microprocessor is replaced or if the thermal material is contaminated or
has come in contact with another object other than its paired microprocessor.
v The microprocessor FRU for this system board includes a heat sink.
v A heat-sink FRU can be ordered separately if the thermal material becomes
contaminated.

Chapter 5. Diagnostics
This chapter describes the diagnostic tools that are available to help you solve
problems that might occur in the blade server.
Note: The blade server uses shared resources that are installed in the BladeCenter
unit. Problems with these shared resources might appear to be in the blade server
(see “Solving shared BladeCenter resource problems” on page 108 for information
about isolating problems with these resources). See the Problem Determination and
Service Guide or the Hardware Maintenance Manual and Troubleshooting Guide for
your BladeCenter unit and other BladeCenter component documentation for
diagnostic procedures for shared BladeCenter components.
If you cannot locate and correct the problem using the information in this chapter,
see Appendix A, “Getting help and technical assistance,” on page 115 for more
information.
Diagnostic tools
The following tools are available to help you diagnose and solve hardware-related
problems:
v POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem. See “POST” for more
information.
v Troubleshooting tables
These tables list problem symptoms and actions to correct the problems. See
“Troubleshooting tables” on page 80 for more information.
v Light path diagnostics
Use the light path diagnostics to diagnose system errors quickly. See “Light path
diagnostics” on page 93 for more information.
v Diagnostic programs, messages, and error codes
The diagnostic programs are the primary method of testing the major
components of the blade server. These programs are stored in read-only memory
(ROM) on the blade server. See “Diagnostic programs, messages, and error
codes” on page 97 for more information.
POST
When you turn on the blade server, it performs a series of tests to check the
operation of the blade server components and some optional devices in the blade
server. This series of tests is called the power-on self-test, or POST.
If a power-on password is set, you must type the password and press Enter, when
prompted, for POST to run.
If POST is completed without detecting any problems, a single beep sounds, and
the blade server startup is completed.
If POST detects a problem, more than one beep might sound, or an error message
is displayed. See “Beep code descriptions” on page 52 and “POST error codes” on
page 63 for more information.
© Copyright IBM Corp. 2007 51
Page 68
POST beep codes
A beep code is a combination of short or long beeps or a series of short beeps that
are separated by pauses. For example, a “1-2-3” beep code is one short beep, a
pause, two short beeps, a pause, and three short beeps. A beep code other than
one beep indicates that POST has detected a problem. To determine the meaning
of a beep code, see “Beep code descriptions.” If no beep code sounds, see
“No-beep symptoms” on page 56.
Beep code descriptions
The following table describes the beep codes and suggested actions to correct the
detected problems.
A single problem might cause more than one error message. When this occurs,
correct the cause of the first error message. The other error messages usually will
not occur the next time POST runs.
Exception: If there are multiple error codes or light path diagnostics LEDs that
indicate a microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 84 for information
about diagnosing microprocessor problems.

Error logs
The BMC log contains all system status messages from the blade server service
processor. The management-module event log in your BladeCenter unit contains
messages that were generated on each blade server during POST and status
messages from the BladeCenter service processor. (See the Management Module
User’s Guide for more information.)
The following illustration shows an example of a BMC log entry.
BMC System Event Log
---------------------------------------------------------Get Next Entry

Entry Number= 00005 / 00011

Important:
v 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.
v The management-module event log in your BladeCenter unit lists messages
according to the position of the blade server in the blade bays. If a blade server
is moved from one bay to another, the management-module event log will report
messages for that blade server using the new bay number; messages for that
blade server that were generated before the move will still be listed using the
previous bay number.
BMC log is limited in size. When the log is full, new entries will not overwrite
The
existing entries; therefore, you must periodically clear the BMC log through the
Configuration/Setup Utility program (the menu choices are described in the
Installation and User’s Guide.) When you are troubleshooting an error, be sure to
clear the BMC log so that you can find current errors more easily.
Entries that are written to the BMC log during the early phase of POST show an
incorrect date and time as the default time stamp; however, the date and time are
corrected as POST continues.
Each BMC log entry appears on its own page. To display all the data for an entry,
use the Up Arrow (↑) and Down Arrow (↓) keys or the Page Up and Page Down
keys. To move from one entry to the next, select Get Next Entry or Get Previous
Entry.
Chapter 5. Diagnostics 57
Page 74
The BMC log indicates an assertion event when an event has occurred. It indicates
a deassertion event when the event is no longer occurring.
Some of the error codes and messages in the BMC log are abbreviated.
You can view the contents of the BMC log from the Configuration/Setup Utility
program and from the diagnostic programs.
When you are troubleshooting PCI-X slots (I/O slots), note that the error logs report
the PCI-X buses numerically. The numerical assignments vary depending on the
configuration. You can check the assignments by running the Configuration/Setup
Utility program (see the Installation and User’s Guide for more information).
Viewing the BMC log from the Configuration/Setup Utility
program
For complete information about using the Configuration/Setup Utility program, see
the Installation and User’s Guide.
To view the BMC log, complete the following steps:
1. Turn on the blade server.
2. When the prompt Press F1 for Configuration/Setup appears, press F1. If you
have set a power-on password, you must type the password and press Enter to
start the Configuration/Setup Utility program.
3. Select Advanced Settings, select Baseboard Management Controller (BMC)
settings, →BMC System Event Log.
Viewing the BMC log from the diagnostic programs
The BMC log contains the same information, whether it is viewed from the
Configuration/Setup Utility program or from the diagnostic programs.
For information about using the diagnostic programs, see “Running the diagnostic
programs” on page 98.
To view the BMC log, complete the following steps:
1. If the blade server is running, turn off the blade server.
2. Turn on the blade server.
3. When the prompt F2 for Diagnostics appears, press F2.
4. From the top of the screen, select Hardware Info.
5. From the list, select BMC Log.

Checkout procedure
The checkout procedure is the sequence of tasks that you should follow to
diagnose a problem in the blade server.
About the checkout procedure
Before performing the checkout procedure for diagnosing hardware problems,
review the following information:
v Read the safety information that begins on page vii.
v The diagnostic programs provide the primary methods of testing the major
components of the blade server. If you are not sure whether a problem is caused
by the hardware or by the software, you can use the diagnostic programs to
confirm that the hardware is working correctly.
v When you run the diagnostic programs, a single problem might cause more than
one error message. When this happens, correct the cause of the first error
message. The other error messages usually will not occur the next time you run
the diagnostic programs.
Exception: If there are multiple error codes or light path diagnostics LEDs that
indicate a microprocessor error, the error might be in a microprocessor or in a
microprocessor socket. See “Microprocessor problems” on page 84 for
information about diagnosing microprocessor problems.
v If the blade server is halted and a POST error code is displayed, see “POST
error codes” on page 63. If the blade server is halted and no error message is
displayed, see “Troubleshooting tables” on page 80 and “Solving undetermined
problems” on page 112.
v For intermittent problems, check the error log; see “Error logs” on page 57 and
“Diagnostic programs, messages, and error codes” on page 97.
v If no LEDs are lit on the blade server front panel, verify the blade server status
and errors in the management-module Web interface; also see “Solving
undetermined problems” on page 112.
v If device errors occur, see “Troubleshooting tables” on page 80.
Chapter 5. Diagnostics 79
Page 96
Performing the checkout procedure
To perform the checkout procedure, complete the following steps:
1. If the blade server is running, turn off the blade server.
2. Turn on the blade server. Make sure that the blade server has control of the
video (the keyboard/video/mouse button is lit). If the blade server does not start,
see “Troubleshooting tables.”
3. Record any POST beep codes that sound or POST error messages that are
displayed on the monitor. If an error is displayed, look up the first error in the
“POST error codes” on page 63.
4. Check the control panel blade-error LED; if it is lit, check the light path
diagnostics LEDs (see “Light path diagnostics” on page 93).
5. Check for the following results:
v Successful completion of POST, indicated by a single beep.
v Successful completion of startup, indicated by a readable display of the
operating-system desktop.
Did a single beep sound and are there readable instructions on the main menu?
6.
v No: Find the failure symptom in “Troubleshooting tables”; if necessary, see
“Solving undetermined problems” on page 112.
v Yes: Run the diagnostic programs (see “Running the diagnostic programs” on
page 98).
– If you receive an error, see “Diagnostic error codes” on page 100.
– If the diagnostic programs were completed successfully and you still
suspect a problem, see “Solving undetermined problems” on page 112.
Troubleshooting tables
Use the troubleshooting tables to find solutions to problems that have identifiable
symptoms. If these symptoms relate to shared BladeCenter unit resources, see
“Solving shared BladeCenter resource problems” on page 108.
If you cannot find the problem in these tables, see “Running the diagnostic
programs” on page 98 for information about testing the blade server.
If you have just added new software or a new optional device, and the blade server
is not working, complete the following steps before using the troubleshooting tables:
1. Remove the software or device that you just added.
2. Run the diagnostic tests to determine whether the blade server is running
correctly.
3. Reinstall the new software or new device.

Symptom Action
Not all drives are recognized by
the Fixed Disk or SAS Attached
Disk diagnostic test.
The blade server stops
responding during the Fixed
Disk or SAS Attached Disk
diagnostic test.
A hard disk drive passes the
Fixed Disk or SAS Attached
Disk diagnostics test, but the
problem remains.
Remove the drive that is indicated by the diagnostic tests; then, run the Fixed Disk
or SAS Attached Disk diagnostic test again. If the remaining drives are recognized,
replace the drive that you removed with a new one.
Remove the hard disk drive that was being tested when the blade server stopped
responding, and run the diagnostic test again. If the Fixed Disk or SAS Attached
Disk diagnostic test runs successfully, replace the drive that you removed with a
new one.
Run the SAS Fixed Disk or SAS Attached Disk diagnostic test again. If the
diagnostics continue to pass but the drive continues to have a problem, replace the
drive with a new one.
Intermittent problems
v Follow the suggested actions in the order in which they are listed in the Action column until the problem
is solved.
v See Chapter 3, “Parts listing, Types 1885 and 8853,” on page 15 to determine which components are CRUs
