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 that you are working on. 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.

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, as specified in the

documentation for your BladeCenter unit type.

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

4. Remove the cover.

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, nongrounded 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.

vi AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

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.

v Use extreme care when measuring 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.

CD/diskette/USB select button

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 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.

You can also press keyboard keys in the following sequence to switch keyboard, mouse, and video 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.

Although the keyboard that is attached to the BladeCenter unit is a PS/2-style keyboard, internal communication with it is through the USB. The operating system in the blade server must provide USB support for the blade server to recognize and use the keyboard and mouse. When you are not running an operating system that has USB device drivers, such as in the following situations, the keyboard responds very slowly:

v Running the blade server integrated diagnostics

v Running a BIOS update diskette on a blade server

v Updating the diagnostics on a blade server

v Running the Broadcom firmware CD for a blade server

If there is no response when you press the keyboard/video/mouse select button, you can use the management-module Web interface to determine whether local control has been disabled on the blade server.

4 AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

If you install a supported Microsoft Windows operating system on the blade server

while it is not the current owner of the keyboard, mouse, and video, a delay of up to

1 minute occurs the first time you switch the keyboard, mouse, and video to the

blade server. During this one-time-only delay, the blade server device manager

enumerates the keyboard, mouse, and video and loads the device drivers. All

subsequent switching takes place in the normal keyboard/video/mouse switching

time frame (up to 20 seconds).

CD/diskette/USB select button: Press this button to associate the shared

BladeCenter unit removable-media drives and USB ports with the blade server. The

LED on the button flashes while the request is being processed then is lit when the

ownership of the removable-media drives and USB ports has been transferred to

the blade server. It can take approximately 20 seconds for the operating system in

the blade server to recognize the removable-media drives and USB ports.

The operating system in the blade server must provide USB support for the blade

server to recognize and use the removable-media drives and USB ports. The

BladeCenter unit uses USB for internal communication with these devices. If there

is no response when you press the CD/diskette/USB select button, you can use the

management-module Web interface to determine whether local control has been

disabled on the blade server.

Activity LED: When this green LED is lit, it indicates that there is activity on the

hard disk drive or network.

Location LED: When this blue LED is lit, it has been turned on by the system

administrator to aid in visually locating the blade server. The location LED on the

BladeCenter unit will be lit also. The location LED can be turned off through the

management-module Web interface or through IBM Director Console.

Information LED: When this amber LED is lit, it indicates that information about a

system error for the blade server has been placed in the Management Module

Event Log. The information LED can be turned off through the management-module

Web interface or through IBM Director Console.

Blade-error LED: When this amber LED is lit, it indicates that a system error has

occurred in the blade server. The blade-error LED will turn off only after the error is

corrected.

Power-control button: This button is behind the control panel door. Press this

button to turn on or turn off the blade server.

Note: The power-control button has effect only if local power control is enabled for

the blade server. Local power control is enabled and disabled through the

management-module Web interface.

Power-on LED: This green LED indicates the power status of the blade server in

the following manner:

v Flashing rapidly: The service processor (BMC) on the blade server is

handshaking with the management module.

v Flashing slowly: The blade server has power but is not turned on.

v Lit continuously: The blade server has power and is turned on.

Chapter 1. Introduction 5

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 You can press the power-control button on the front of the blade server (behind

the control panel door, see “Blade server control panel buttons 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 blade server power-control button. During this time, the service processor in the management module is initializing; therefore, the power-control button on the blade server does not respond.

2. While the blade server is powering-up, the power-on LED on the front of the server is lit. See “Blade server control panel buttons and LEDs” on page 4 for the power-on LED states.

v If a power failure occurs, the BladeCenter unit and then the blade server can

start automatically when power is restored (if the blade server is configured through the management module to do so).

v You can turn on the blade server remotely by means of the service processor in

the management module.

v If the operating system supports the Wake on LAN feature and the blade server

power-on LED is flashing slowly, the Wake on LAN feature can turn on the blade server, if the Wake on LAN feature has not been disabled through the management module.

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.

Shut down the operating system before you turn off the blade server. See the operating-system documentation for information about shutting down the operating system.

The blade server can be turned off in any of the following ways:

v You can press the power-control button on the blade server (behind the control

panel door, see “Blade server control panel buttons and LEDs” on page 4). This also starts an orderly shutdown of the operating system, if this feature is supported by the operating system.

Note: After turning off the blade server, wait at least 5 seconds before you press the power-control button to turn on the blade server again.

v If the operating system stops functioning, you can press and hold the

power-control button for more than 4 seconds to turn off the blade server.

v The management module can turn off the blade server.

Chapter 2. Diagnostics

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

If you cannot locate and correct the problem using the information in this chapter, see Appendix A, “Getting help and technical assistance,” on page 91 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 27 for more information.

v Light path diagnostics

Use the light path diagnostics to diagnose system errors quickly. See “Light path diagnostics” on page 40 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 43 for more information.

POST

When you turn on the blade server, it performs a series of tests to check the operation of 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 prompted, for POST to run.

If POST is completed without detecting any problems, a single beep sounds, and the 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 10 and “POST error codes” on page 19 for more information.

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” on page 10. If no beep code sounds, see “No-beep symptoms” on page 16.

16 AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

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 documentation for the management module in your BladeCenter unit type.)

The following illustration shows an example of a BMC log entry.

---------------------------------------------------------Get Next Entry Get Previous Entry Clear BMC SEL

Entry Number= 00005 / 00011 Record ID= 0005 Record Type= 02 Timestamp= 2005/01/25 16:15:17 Entry Details: Generator ID= 0020

BMC System Event Log

Sensor Type= 04 Assertion Event Fan Threshold Lower Non-critical - going high

Sensor Number= 40 Event Direction/Type= 01

Event Data= 52 00 1A

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 prior to the move will still be listed using the previous bay number.

The BMC log is limited in size. When the log is full, new entries will not overwrite 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 2. Diagnostics 17

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 troubleshooting PCI-X 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 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, and then select 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 43.

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.

For complete information about using the Configuration/Setup Utility program, see the Installation and User’s Guide.

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 server has control of the video (the keyboard/video/mouse button is lit). If the server does not start, see “Troubleshooting tables.”

3. Record any POST beep codes that are heard 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 19.

4. Check the control panel blade-error LED; if it is lit, check the light path diagnostics LEDs (see “Light path diagnostics” on page 40).

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

6. Did a single beep sound and are there readable instructions on the main menu?

v No: Find the failure symptom in “Troubleshooting tables”; if necessary, see

“Solving undetermined problems” on page 50.

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

page 43).

– If you receive an error, see “Diagnostic error codes” on page 45.

– If the diagnostic programs were completed successfully and you still

suspect a problem, see “Solving undetermined problems” on page 50.

Troubleshooting tables

Use the troubleshooting tables to find solutions to problems that have identifiable symptoms.

If you cannot find the problem in these tables, see “Running the diagnostic programs” on page 43 for information about testing the server.

If you have just added new software or a new optional device and the server is not working, complete the following steps before using the troubleshooting tables:

CD or DVD drive 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, Type 8850,” on page 53 to determine which components are customer

replaceable units (CRU) and which components are field replaceable units (FRU).

v If an action step is preceded by “(Trained service technician only),” that step must be performed only by a

trained service technician.

Symptom Action

The CD or DVD drive is not recognized.

A CD or DVD is not working correctly.

The CD or DVD drive tray is not working.

The CD or DVD drive is detected as /dev/sr0 by SUSE LINUX. (If the SUSE LINUX operating system is installed remotely onto a blade server that is not the current owner of the media tray [CD or DVD drive, diskette drive, and USB port], SUSE LINUX detects the CD or DVD drive as /dev/sr0 instead of /dev/cdrom.)

The CD or DVD drive is not recognized after being switched back to the blade server running Windows 2000 Advanced Server with SP3 applied. (When the CD or DVD drive owned by blade server x is switched to another blade server, then is switched back to blade server x, the operating system in blade server x no longer recognizes the CD or DVD drive. This happens when you have not safely stopped the drives before switching ownership of the media tray [CD or DVD drive, diskette drive, and USB port].)

1. Make sure that:

v All cables and jumpers are installed correctly.

v The correct device driver is installed for the CD or DVD drive.

2. Reseat the CD or DVD drive.

3. Replace the CD or DVD drive.

1. Clean the CD or DVD.

2. Reseat the CD or DVD drive.

3. Replace the CD or DVD drive.

Note: The blade server must have ownership of the CD or DVD drive.

1. Insert the end of a straightened paper clip into the manual tray-release opening.

2. Reseat the CD or DVD drive.

3. Replace the CD or DVD drive.

Establish a link between /dev/sr0 and /dev/cdrom as follows:

1. Enter the following command:

rm /dev/cdrom; ln -s /dev/sr0 /dev/cdrom

2. Insert the following line in the /etc/fstab file:

/dev/cdrom /media/cdrom auto ro,noauto,user,exec 0 0

Note: Because the BladeCenter unit uses a USB bus to communicate with the media tray devices, switching ownership of the media tray to another blade server is the same as unplugging a USB device. Before switching ownership of the CD or DVD drive (media tray) to another blade server, safely stop the media tray devices on the blade server that currently owns the media tray, as follows:

1. Double-click the Unplug/Eject Hardware icon in the Windows taskbar at the bottom right of the screen.

2. Select USB Floppy and click Stop.

3. Select USB Mass Storage Device and click Stop.

4. Click Close.

You can now safely switch ownership of the media tray to another blade server.

Light path diagnostics

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

Some internal components contain LEDs that can be lit for a short time after you remove the blade server from the BladeCenter unit. After you remove the blade server, you can press and hold the light path diagnostics switch for a maximum of 25 seconds to light the LEDs that were lit before you removed the blade server from the BladeCenter unit. Power remains available to light these LEDs for up to 24 hours after the component is removed from the server. The following components have this feature:

v Microprocessors

v Memory modules (DIMMs)

v Light path diagnostics panel

Viewing the light path diagnostics LEDs

Before working inside the server to view light path diagnostics LEDs, read the safety information that begins on page v and “Handling static-sensitive devices” on page 60.

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

1. Look at the control panel on the front of the server (see “Blade server control panel buttons and LEDs” on page 4).

v If the information LED is lit, it indicates that information about a suboptimal

condition in the server is available in the BMC log or in the management-module event log.

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

2. To view the light path diagnostics panel and LEDs, complete the following steps:

a. Remove the blade server from the BladeCenter unit.

b. Place the blade server on a flat, static-protective surface.

c. Remove the cover from the blade server.

d. Press and hold the light path diagnostics switch to relight the LEDs that

were lit before you removed the blade server from the BladeCenter unit. The LEDs will remain lit for as long as you press the switch, to a maximum of 25 seconds.

Maintenance Manual and Troubleshooting Guide or Problem Determination and Service Guide for your BladeCenter unit

type for more information).

2. Make sure that the room temperature is not too high. (See “LS20 Type 8850 specifications for non-NEBS/ETSI environments” on page 3 for temperature information.)

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 error codes” on page 45.

Running the diagnostic programs

To run the diagnostic programs, 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 either Extended or Basic.

5. From the pulldown menu, select the test that you want to run, and follow the instructions on the screen.

For help with the diagnostic programs, press F1. You also can press F1 from within a help screen to obtain online documentation from which you can select different categories. To exit from the help information, press Esc.

To determine what action you should take as a result of a diagnostic text message or error code, see the table in “Diagnostic error codes” on page 45.

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.

Chapter 2. Diagnostics 43

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.

If the blade server stops during testing and you cannot continue, restart the blade server and try running the diagnostic programs again. If the problem remains, replace the component that was being tested when the blade server stopped.

The diagnostic programs assume that a keyboard and mouse are attached to the BladeCenter unit and that the blade server controls them. If you run the diagnostic programs with either no mouse or a mouse attached to the BladeCenter unit that is not controlled by the blade server, you cannot use the Next Cat and Prev Cat buttons to select categories. All other mouse-selectable functions are available through function keys.

To view server configuration information (such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on), select Hardware Info from the top of the screen.

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.

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.

44 AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

Viewing the test log

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

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

Note: 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 error codes

The following table describes the error codes that the diagnostic programs might generate and suggested actions to correct the detected problems.

If the diagnostic programs generate error codes that are not listed in the table, make sure that the latest level of the BIOS code is installed.

In the error codes, x can be any numeral or letter. However, if the three-digit number in the central position of the code is 000, 195, or 197, do not replace a CRU or FRU. These numbers appearing in the central position of the code have the following meanings:

000 The blade server passed the test. Do not replace a CRU or FRU.

195 The Esc key was pressed to end the test. Do not replace a CRU or FRU.

197 This is a warning error, but it does not indicate a hardware failure; do not

Recovering from a BIOS update failure

The server has an advanced recovery feature that will automatically switch to a backup BIOS page if the BIOS code in the server has become damaged, such as from a power failure during an update.

The flash memory of the blade server consists of a primary page and a backup page. If the BIOS code in the primary page is damaged, the baseboard management controller will detect the error and automatically switch to the backup page to start the server. If this happens, a POST message Booted from backup POST/BIOS image is displayed. The backup page version may not be the same version as the primary image.

You can then recover or restore the original primary page BIOS by using a BIOS flash diskette.

To recover the BIOS code and restore the server operation to the primary page, complete the following steps:

1. Download the latest version of the BIOS code from http://www.ibm.com/pc/ support/.

2. Update the BIOS code, following the instructions that come with the update file that you downloaded. This will automatically restore and update the primary page.

3. Restart the blade server.

If that procedure fails, the blade server might not restart correctly or might not display video. To manually restore the BIOS code, complete the following steps:

1. Read the safety information that begins on page v and “Handling static-sensitive devices” on page 60.

2. Turn off the blade server.

3. Remove the blade server from the BladeCenter unit (see “Removing and installing the blade server in a BladeCenter unit” on page 61).

4. Remove the cover (see “Operating the blade server cover” on page 64).

5. Locate the BIOS backup page jumper (J16) on the system board (see “System-board jumpers” on page 7).

6. Move the J16 jumper to pins 3 and 4 to enable the backup page.

7. Replace the cover and reinstall the blade server in the BladeCenter unit, making sure that the media tray is selected by the relevant blade server.

8. Insert the BIOS flash diskette into the diskette drive.

9. Restart the blade server. The system begins the power-on self-test (POST).

10. Select 1 - Update POST/BIOS from the menu that contains various flash (update) options.

11. When you are prompted whether you want to move the current POST/BIOS

image to the backup ROM location, press N.

Attention: If you press Y, the damaged BIOS will be copied into the secondary page.

12. When you are prompted whether you want to save the current code to a diskette, press N.

13. Select Update the BIOS.

Attention: Do not restart the blade server at this time.

14. Remove the flash diskette from the diskette drive.

Chapter 2. Diagnostics 49

15. Turn off the blade server, remove it from the BladeCenter unit, and remove the cover of the blade server.

16. Move the J16 jumper to pins 1 and 2 to return to normal startup mode.

17. Replace the cover and reinstall the blade server in the BladeCenter unit; then restart the blade server. The system starts up.

Statement 21:

CAUTION: Hazardous energy is present when the blade server is connected to the power source. Always replace the blade cover before installing the blade server.

Service processor (BMC) error codes

The baseboard management controller (BMC) log contains up to 512 of the most recent service processor errors in IPMI format. These messages are a combination of plain text and error code numbers. You can view the BMC log from the Configuration/Setup Utility menu by selecting Advanced Setup > Baseboard Management Controller (BMC) Settings > BMC System Event Log.

You can view additional information and error codes in plain text by viewing the management-module event log in your BladeCenter unit.

Solving SCSI problems

For any SCSI error message, one or more of the following devices might be causing the problem:

v A failing SCSI device (adapter, drive, or controller)

v An improper SCSI configuration

v Duplicate SCSI IDs in the same SCSI chain

For any SCSI error message, make sure that the SCSI devices are configured correctly.

Solving undetermined problems

Note: When you are diagnosing a problem in the LS20 Type 8850, you must

determine whether the problem is in the blade server or in the BladeCenter unit.

v If all of the blade servers have the same symptom, it is probably a BladeCenter

unit problem; for more information, see the Hardware Maintenance Manual and Troubleshooting Guide or Problem Determination and Service Guide for your BladeCenter unit type.

v If the BladeCenter unit contains more than one blade server and only one of the

blade servers has the problem, troubleshoot the blade server that has the problem.

If the diagnostic tests did not diagnose the failure or if the blade server is inoperative, use the information in this section.

50 AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

If you suspect that a software problem is causing failures (continuous or intermittent), see “Software problems” on page 39.

Damaged data in CMOS memory or damaged BIOS code can cause undetermined problems. To reset the CMOS data, remove and replace the battery to override the power-on password and clear the CMOS memory; see “Battery” on page 76. If you suspect that the BIOS code is damaged, see “Recovering from a BIOS update failure” on page 49.

Check the LEDs on all the power supplies of the BladeCenter unit where the blade server is installed. If the LEDs indicate that the power supplies are working correctly, and reseating the blade server does not correct the problem, complete the following steps:

1. Make sure that the control panel connector is correctly seated on the system board (see “System-board connectors” on page 7 for the location of the connector).

2. If no LEDs on the control panel are working, replace the bezel assembly; then, try to power-on the blade server from the BladeCenter Web interface (see the BladeCenter documentation for more information).

3. Turn off the blade server.

4. Remove the blade server from the BladeCenter unit and remove the cover.

5. Make sure that the server is cabled correctly.

6. Remove or disconnect the following devices, one at a time, until you find the failure. Reinstall, turn on, and reconfigure the blade server each time.

v I/O adapter. v Drives. v Memory modules. The minimum configuration requirement is 1 GB (two 512

MB DIMMs).

The following minimum configuration is required for the blade server to start:

v System board v One microprocessor v Two 512 MB DIMMs v A functioning BladeCenter unit

7. Install and turn on the blade server. If the problem remains, suspect the following components in the following order: a. DIMM b. System board c. Microprocessor

If the problem is solved when you remove an I/O adapter from the server but the problem recurs when you reinstall the same adapter, suspect the adapter; if the problem recurs when you replace the adapter with a different one, suspect the system board.

If you suspect a networking problem and the blade server passes all the system tests, suspect a network cabling problem that is external to the system.

Chapter 4. Removing and replacing blade server components

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 service that is designated for your server.

v Field replaceable unit (FRU): FRUs must be installed only by trained service

technicians.

See Chapter 3, “Parts listing, Type 8850,” on page 53 to determine 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 v and the guidelines in

“Handling static-sensitive devices” on page 60. This information will help you work safely.

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 hot-swap blade server from the BladeCenter

must shut down the operating system and turn off the blade server. You 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 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/pc/

us/compat/.

unit, you

System reliability guidelines

To help ensure proper cooling and system reliability, observe the following guidelines:

v Make sure that microprocessor socket 2 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 the microprocessor socket 1.

v To maintain proper system cooling, do not operate the BladeCenter unit without a

blade server, expansion unit, or filler blade installed in each blade bay. See the documentation for your BladeCenter unit type for additional information.

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 ESD connector on the front or back of the BladeCenter T 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 its 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 its 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 its 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 installing the blade server in a BladeCenter unit

Attention:

v To maintain proper system cooling, do not operate the BladeCenter unit without a

blade server, expansion unit, or filler blade installed in each blade bay.

v Note the bay number. Reinstalling a blade server into a different bay than the

one from which it was removed could have unintended consequences. Some configuration information and update options are established according to bay number; if you reinstall the blade server into a different bay, you might need to reconfigure the blade server.

To remove the blade server from a BladeCenter unit, complete the following steps.

1. If the blade server is operating, shut down the operating system; then, press the power-control button (behind the blade server control panel door) to turn off the blade server (see “Turning off the blade server” on page 6 for more information).

Attention: Wait at least 30 seconds, until the hard disk drives stop spinning, before proceeding to the next step.

2. Open the two release levers as shown in the illustration. The blade server moves out of the bay approximately 0.6 cm (0.25 inch).

3. Pull the blade server out of the bay. Spring-loaded doors further back in the bay move into place to cover the bay temporarily.

4. Place either a filler blade or another blade server in the bay within 1 minute. The recessed spring-loaded doors will move out of the way as you insert the blade or filler blade.

Chapter 4. Removing and replacing blade server components 61

To install a blade server in a BladeCenter unit, complete the following steps.

Statement 21:

CAUTION: Hazardous energy is present when the blade server is connected to the power source. Always replace the blade cover before installing the blade server.

1. Read the safety information that begins on page v and “Installation guidelines” on page 59 through “Handling static-sensitive devices” on page 60.

2. If you have not done so already, install any options that you want, such as SCSI drives or memory, in the blade server.

3. Make sure that the release levers on the blade server are in the open position (perpendicular to the blade server).

4. If you installed a filler blade or another blade in the bay from which you removed the blade server, remove it from the bay.

Attention: You must install the blade server in the same blade bay from which you removed it. Some blade server configuration information and update options are established according to bay number. Reinstalling a blade server into a different blade bay from the one from which it was removed could have unintended consequences, and you might have to reconfigure the blade server.

5. Slide the blade server into the blade bay from which you removed it until it stops. The spring-loaded doors farther back in the bay that cover the bay opening move out of the way as you insert the blade server.

Memory modules (DIMMs)

The following notes describe the types of dual inline memory modules (DIMMs) that the blade server supports and other information that you must consider when installing DIMMs:

v The system board contains four DIMM connectors and supports two-way memory

interleaving.

v As of the date of this publication, the DIMM options that are available for the

blade server are 512 MB, 1 GB, and 2 GB. Depending on the memory configuration set in blade server BIOS, as of the date of this publication, the blade server can support a minimum of 1 GB and a maximum of 8 GB of system memory.

v For optimum performance, one pair of DIMMs is associated with each

microprocessor. The blade server comes with two DIMMs installed for each microprocessor.

Pair DIMM connectors

Microprocessor 1 1 (J31) and 2 (J30) Microprocessor 2 3 (J4) and 4 (J2)

v One pair of DIMMs can be used when two microprocessors are installed, but the

blade server will operate at a lower level of efficiency. When one microprocessor is installed, you can only install DIMMs in the DIMM connectors that are associated with the microprocessor.

v When you install memory, you must install a pair of matched DIMMs.

v Both DIMMs in a pair must be the same size, speed, type, technology, and

physical design. You can mix compatible DIMMs from different manufacturers.

v The second pair does not have to be DIMMs of the same size, speed, type,

technology, and physical design as the first pair.

v Install only 2.6 V, 184-pin, DDR1, PC3200, VLP, registered SDRAM with ECC

DIMMs. For a current list of supported DIMMs for the blade server, see the ServerProven list at http://www.ibm.com/pc/us/compat/.

v Installing or removing DIMMs changes the configuration information for the blade

server. After installing or removing a DIMM, you must change and save the new configuration information by using the Configuration/Setup Utility program. When you restart the blade server, it displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings. See “Configuration/Setup Utility menu choices” on page 87 for more information.

Removing and replacing FRUs

FRUs must be installed only by trained service technicians.

The illustrations in this document might differ slightly from your hardware.

Microprocessor

Read the following important guidelines before removing a microprocessor that is not faulty (for example, when replacing the system board assembly).

Attention: Do not use a thermal grease syringe with this FRU.

If you are not replacing a defective heat sink or microprocessor, the grease on the heat sink and microprocessor will remain effective if you perform the following steps:

1. Carefully handle the heat sink and microprocessor when removing or installing these components. Do not touch the grease or otherwise allow it to become contaminated.

2. For dual-microprocessor systems, since 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 grease remains evenly distributed between each heat sink and microprocessor.)

The following sections contain the instructions for removing and replacing a microprocessor.

Notes:

v The heat sink FRU is packaged with the thermal grease applied to the underside.

This thermal grease is not available as a separate FRU. The heat sink must be replaced when new grease is required, such as when a defective microprocessor is replaced or if the grease is contaminated.

v If you need to install a new heat sink for any reason, first remove the thermal

grease from the microprocessor with an alcohol pad before attaching the new heat sink.

v The microprocessor FRU for this system board includes a heat sink.

v A heat sink FRU can be ordered separately if the grease becomes contaminated.

To remove a microprocessor, complete the following steps:

1. Read the safety information that begins on page v, the “Installation guidelines” on page 59 and “Handling static-sensitive devices” on page 60.

2. Shut down the operating system, turn off the blade server, and remove the blade server from the BladeCenter unit (see “Removing and installing the blade server in a BladeCenter unit” on page 61).

3. Carefully lay the blade server on a flat, non-conductive surface.

4. Open the blade server cover (see “Operating the blade server cover” on page 64 for instructions).

5. Remove the bezel assembly (see “Removing and replacing the bezel assembly” on page 66 for instructions).

78 AMD Opteron LS20 Type 8850 for IBM BladeCenter: Problem Determination and Service Guide

6. Identify the microprocessor to be removed.

Note: If you are replacing a failed microprocessor, verify that you have selected the correct microprocessor for replacement (see “Light path diagnostics” on page 40).

7. Remove the heat sink:

a. Loosen two captive screws on one side of the heat sink fully; then, loosen

the other two captive screws.

Note: Loosening the screws on one side fully before loosening the other screws will help to break the thermal bond that adheres the heat sink to the microprocessor.

b. Gently pull the heat sink off of the microprocessor.

Attention: Do not use any tools or sharp objects to lift the locking lever on the microprocessor socket. Doing so might result in permanent damage to the system board.

8. Release the microprocessor locking lever by moving it away from the microprocessor socket and around the locking lever retainer tab; then, rotate it upward to the fully open position.

5. Install a heat sink on the microprocessor.

Attention:

v Do not set down the heat sink after you remove the plastic cover.

v Do not touch the thermal grease on the bottom of the heat sink. Touching the

thermal grease will contaminate it. If the thermal grease on the microprocessor or heat sink becomes contaminated, contact your service technician.

Thermal grease

Heat sink

a. Remove the plastic protective cover from the thermal material on the bottom

of the heat sink.

b. Make sure that the thermal material is still on the bottom of the heat sink;

then, align and place the heat sink on top of the microprocessor in the retention bracket, grease side down. Press firmly on the heat sink.

c. Align the four captive screws on the heat sink with the holes on the

heat-sink retention module.

d. Press firmly on the captive screws and tighten them, alternating between

screws until they are tight. Do not overtighten the screws by using excessive force. If you are using a torque wrench, tighten the screws to 1.00 to 1.26 Newton-meters (Nm) (8.85 to 11.15 inch-pounds).

Attention: If you need to remove the heat sink after installing it, note that the thermal material might have formed a strong bond between the heat sink and the microprocessor. Do not force the heat sink and microprocessor apart; doing so can damage the microprocessor pins. Loosening the captive screws on one side of the heat sink fully before loosening the captive screws on the other side helps break the bond between the components without damaging them.

6. Install the bezel assembly (see “Removing and replacing the bezel assembly” on page 66 for instructions).

7. Install the blade server cover (see “Operating the blade server cover” on page 64 for instructions).
