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.

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 “Power

cords” on page 84.

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

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, 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.

viii IBM System x3650 Type 7979 and 1914: 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.

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.

causes the Remote Supervisor Adapter II SlimLine to execute the Built In Self Test (BIST).

6 Off Power-on override. When this switch is toggled to On, it forces the power on,

overriding the power-on button.

5 Off Power-on password override. Changing the position of this switch bypasses the

power-on password check the next time the server is turned on and starts the Configuration/Setup Utility program so that you can change or delete the power-on password. You do not have to move the switch back to the default position after the password is overridden.

Changing the position of this switch does not affect the administrator password check if an administrator password is set.

See the User’s Guide on the IBM System x Documentation CD for additional information about the power-on password.

4 Off Force BMC update. When this switch is toggled to On, it causes an update of BMC

firmware from the diskette drive.

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 163 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 36.

v Light path diagnostics

Use the light path diagnostics to diagnose system errors quickly. See “Light path diagnostics” on page 49 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. The diagnostic programs are in read-only memory on the server. See “Diagnostic programs, messages, and error codes” on page 54 for more information.

POST

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 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 “POST beep codes” and “POST error codes” on page 28 for more information.

POST beep codes

A beep code is a combination of short or long beeps or 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 18. If no beep code sounds, see “No-beep symptoms” on page 24.

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 the microprocessor or in the microprocessor socket. See “Microprocessor problems” on page 41 for information about diagnosing microprocessor 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 7979 and 1914 server,” on page 79 to determine which components are

Error logs

The POST error log contains the three most recent error codes and messages that were generated during POST. The BMC system event log contains monitored events, such as a threshold that is reached or a device that fails. The system event/error log, which is available only when an optional Remote Supervisor Adapter II SlimLine is installed, contains messages that were generated during POST and all system status messages from the service processor.

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

BMC System Event Log

---------------------------------------------------------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

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

Sensor Number= 40 Event Direction/Type= 01

Event Data= 52 00 1A

The BMC system event log is limited in size. When the log is full, new entries will not overwrite existing entries; therefore, you must periodically clear the BMC system event log through the Configuration/Setup Utility program (the menu choices are described in the User’s Guide). When you are troubleshooting an error, be sure to clear the BMC system event log so that you can find current errors more easily.

Entries that are written to the BMC system event 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 system event/error log entry appears on its own page. To move from one entry to the next, use the up-arrow and down-arrow keys.

If you view the BMC system event log through the Web interface of the optional Remote Supervisor Adapter II SlimLine, the messages can be translated.

You can view the contents of the POST error log, the BMC system event log, and the system event/error log from the Configuration/Setup Utility program. You can view the contents of the BMC system event log also from the diagnostic programs.

When you are troubleshooting PCI slots, note that the error logs report the PCI buses numerically. The numerical assignments vary depending on the configuration. You can check the assignments by running the Configuration/Setup Utility program (see the User’s Guide for more information).

Chapter 2. Diagnostics 33

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 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 server, such as the system board, Ethernet controller, keyboard, mouse (pointing device), serial ports, and hard disk drives. Yo u 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 there are multiple error codes or LEDs that indicate a

microprocessor error, the error might be in the microprocessor or in the microprocessor socket. See “Microprocessor problems” on page 41 for information about diagnosing microprocessor problems.

v Before running 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:

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.

v If the server is halted and a POST error code is displayed, see “Error logs” on

page 26. If the server is halted and no error message is displayed, see “Troubleshooting tables” on page 36 and “Solving undetermined problems” on page 76.

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

page 74.

v For intermittent problems, check the error log; see “Error logs” on page 26 and

“Diagnostic programs, messages, and error codes” on page 54.

34 IBM System x3650 Type 7979 and 1914: Problem Determination and Service Guide

If the server is part of a shared hard disk drive cluster, run one test

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.

Complete the following steps:

a. Check the power supply LEDs, see “Power-supply LEDs” on page 53.

b. Turn off the server and all external devices.

c. Check all internal and external devices for compatibility at

http://www.ibm.com/servers/eserver/serverproven/compat/us/.

d. Make sure the server is cabled correctly.

e. Check all cables and power cords.

f. Set all display controls to the middle positions.

g. Turn on all external devices.

h. Turn on the server. If the server does not start, see “Troubleshooting tables”

on page 36.

i. Check the system-error LED on the operator information panel. If it is

flashing, check the LEDs on the system board (see “System-board LEDs” on page 15).

j. Check for the following results:

v Successful completion of POST (see “POST” on page 17 for more

information)

v Successful completion of startup

Did more than one beep sound?

Note: A single beep indicates successful completion of POST and is not an

error.

v No: (No beeps sounded) Find the failure symptom in “Troubleshooting tables”

on page 36; if necessary, run the diagnostic programs (see “Running the diagnostic programs” on page 55).

– If you receive an error, see “Diagnostic error codes” on page 56.

– If the diagnostic programs were completed successfully and you still

suspect a problem, see “Solving undetermined problems” on page 76.

Yes: Find the beep code in “POST beep codes” on page 17; if necessary,

see “Solving undetermined problems” on page 76.

Chapter 2. Diagnostics 35

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 55 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:

1. Check the system-error LED on the operator information panel; if it is lit, check the LEDs on the system board (see “System-board LEDs” on page 15).

2. Remove the software or device that you just added.

3. Run the diagnostic tests to determine whether the server is running correctly.

4. Reinstall the new software or new device.

Light path diagnostics

Light path 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 working inside the server to view light path diagnostics LEDs, read the safety information that begins on page vii and “Handling static-sensitive devices” on page 89.

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

1. Look at the operator information panel on the front of the server.

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

condition in the server is available in the BMC system event log or in the system event/error log.

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

Note any LEDs that are lit, and then push the light path diagnostics panel back into the server.

Look at the system service label on the top of the server, which gives an overview of internal components that correspond to the LEDs on the light path diagnostics panel. This information and the information in “Light path diagnostics LEDs” on page 52 can often provide enough information to diagnose the error.

3. Remove the server cover and look inside the server for lit LEDs. A lit LED on or beside a component identifies the component that is causing the error.

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 56.

54 IBM System x3650 Type 7979 and 1914: Problem Determination and Service Guide

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 F2 for Diagnostics appears, press F2. If you have set both a

power-on password and an administrator password, you must type the administrator password to run the diagnostic programs.

4. From the top of the screen, select either Extended or Basic.

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

When you are diagnosing hard disk drives, select SCSI Attached Disk Test for the most thorough test. Select Fixed Disk Test for any of the following situations:

v You want to run a faster test.

v The server contains RAID arrays.

v The server contains SATA or IDE hard disk drives.

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 56.

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 there are multiple error codes or diagnostics LEDs that indicate a

microprocessor error, the error might be in a microprocessor or in a microprocessor socket. See “Microprocessor problems” on page 41 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.

The keyboard and mouse (pointing device) tests assume that a keyboard and mouse are attached to the server. If no mouse is attached to the server, you cannot use the Next Cat and Prev Cat buttons to select categories. All other mouse-selectable functions are available through function keys. Yo u can use the regular keyboard test to test a USB keyboard, and you can use the regular mouse test to test a USB mouse.

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.

Chapter 2. Diagnostics 55

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.

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, 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 before initiating the diagnostic programs.

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 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 levels of BIOS, Remote Supervisor Adapter II SlimLine, and ServeRAID code are 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 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 the BIOS code

If the BIOS code has become damaged, such as from a power failure during an update, you can recover the BIOS code using the boot block jumper and a BIOS recovery diskette.

Chapter 2. Diagnostics 65

Notes:

1. You can obtain a BIOS recovery diskette from one of the following sources:

v Download the BIOS code update from the World Wide Web and use it to

make a recovery diskette.

v Contact your IBM service representative.

To create and use a diskette, you must add an optional external diskette drive to

2. the server.

To download the BIOS code update from the World Wide Web, complete the following steps:

1. Go to http://www.ibm.com/servers/eserver/support/xseries/index.html.

2. Select System x3650 from the Hardware list,.

3. Click the Download tab.

4. Download the latest BIOS code update.

5. Create the BIOS recovery diskette, following the instructions that come with the update file that you downloaded.

flash memory of the server consists of a primary page and a backup page. The

The backup page is a protected area that cannot be overwritten. The recovery boot block is a section of code in this protected area that enables the server to start up and to read a recovery diskette. The recovery utility recovers the system BIOS code from the BIOS recovery files on the diskette.

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

1. Turn off the server, and disconnect all power cords and external cables.

2. Remove the server cover. See “Removing the cover” on page 90 for more information.

System event/error log messages

A system event/error log is generated only if a Remote Supervisor Adapter II SlimLine is installed. The system event/error log can contain messages of three types:

Information Information messages do not require action; they record significant

system-level events, such as when the server is started.

Warning Warning messages do not require immediate action; they indicate

possible problems, such as when the recommended maximum ambient temperature is exceeded.

Error Error messages might require action; they indicate system errors,

such as when a fan is not detected.

Each message contains date and time information, and it indicates the source of

the message (POST/BIOS or the service processor).

Note: The BMC system event log, which you can view through the

Configuration/Setup Utility program, also contains many information, warning, and error messages.

In the following example, the system event/error log message indicates that the server was turned on at the recorded time.

- - - - - - - - - - - - - - - - - - - - Date/Time: 2002/05/07 15:52:03 DMI Type: Source: SERVPROC Error Code: System Complex Powered Up Error Code: Error Data: Error Data:

Solving power problems

Power problems can be difficult to solve. For example, a short circuit can exist anywhere on any of the power distribution buses. Usually, a short circuit will cause the power subsystem to shut down because of an overcurrent condition. To diagnose a power problem, use the following general procedure:

74 IBM System x3650 Type 7979 and 1914: Problem Determination and Service Guide

1. Turn off the server and disconnect all ac power cords.

2. Check for loose cables in the power subsystem. Also check for short circuits, for example, if a loose screw is causing a short circuit on a circuit board.

3. If a power-channel error LED on the system board is lit, perform the following steps; otherwise, go to step 4. See “System-board LEDs” on page 15 for the location of the power-channel error LEDs. Table 4 identifies the components associated with each power channel, and the order in which to troubleshoot the components.

a. Disconnect the cables and power cords to all internal and external devices.

Leave the power-supply cords connected.

b. Remove each component that is associated with the LED, one at a time, in

the sequence indicated in Table 4, restarting the server each time, until the cause of the overcurrent condition is identified.

Important: Only a trained service technician should remove or replace a

FRU, such as a microprocessor or the system board. See Chapter 3, “Parts listing, Type 7979 and 1914 server,” on page 79 to determine whether a component is a FRU.

c. Replace the identified component.

Remove the adapters and disconnect the cables and power cords to all internal

4. and external devices until the server is at the minimum configuration that is required for the server to start (see “Solving undetermined problems” on page 76 for the minimum configuration).

5. Reconnect all ac power cords and turn on the server. If the server starts successfully, replace the adapters and devices one at a time until the problem is isolated.

If the server does not start from the minimum configuration, replace the components in the minimum configuration one at a time until the problem is isolated.

Solving Ethernet controller problems

The method that you use to test the Ethernet controller depends on which operating system you are using. See the operating-system documentation for information about Ethernet controllers, and see the Ethernet controller device-driver readme file.

Try the following procedures:

v Make sure that the correct device drivers, which come with the server, are

installed and that they are at the latest level.

v Make sure that the Ethernet cable is installed correctly.

Chapter 2. Diagnostics 75

– The cable must be securely attached at all connections. If the cable is

attached but the problem remains, try a different cable.

– You must use Category 5 cabling.

Determine whether the hub supports auto-negotiation. If it does not, try

configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.

v Check the Ethernet controller LEDs on the rear panel of the server. These LEDs

indicate whether there is a problem with the connector, cable, or hub. – The Ethernet link status LED is lit when the Ethernet controller receives a link

pulse from the hub. If the LED is off, there might be a defective connector or cable or a problem with the hub.

– The Ethernet transmit/receive activity LED is lit when the Ethernet controller

sends or receives data over the Ethernet network. If the Ethernet transmit/receive activity light is off, make sure that the hub and network are operating and that the correct device drivers are installed.

Check the Ethernet activity LED on the rear of the server. The Ethernet activity

LED is lit when data is active on the Ethernet network. If the Ethernet activity LED is off, make sure that the hub and network are operating and that the correct device drivers are installed.

v Check for operating-system-specific causes of the problem. v Make sure that the device drivers on the client and server are using the same

protocol.

the Ethernet controller still cannot connect to the network but the hardware

appears to be working, the network administrator must investigate other possible causes of the error.

Solving undetermined problems

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

If you suspect that a software problem is causing failures (continuous or intermittent), see “Software problems” on page 48.

Damaged data in CMOS memory or damaged BIOS code can cause undetermined problems. To reset the CMOS data, use the CMOS jumper to clear the CMOS memory and override the power-on password; see “System-board switches and jumpers” on page 13. If you suspect that the BIOS code is damaged, see “Recovering the BIOS code” on page 65.

Check the LEDs on all the power supplies (see “Power-supply LEDs” on page 53). If the LEDs indicate that the power supplies are working correctly, complete the following steps:

1. Turn off the server.

2. Make sure that the server is cabled correctly.

3. Remove or disconnect the following devices, one at a time, until you find the failure. Turn on the server and reconfigure it each time.

v Any external devices. v Surge-suppressor device (on the server). v Modem, printer, mouse, and non-IBM devices. v Each adapter. v Hard disk drives. v Memory modules. The minimum configuration requirement is 1 GB (two 512

MB DIMM, in DIMM slots 1 and 4).

v Service processor (Remote Supervisor Adapter II SlimLine).

76 IBM System x3650 Type 7979 and 1914: Problem Determination and Service Guide

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

v One microprocessor v Two 512 MB DIMMs v One power supply v Power backplane v Power cord v ServeRAID SAS controller

Turn on the server. If the problem remains, suspect the following components in

the following order: a. Power backplane b. System board

the problem is solved when you remove an adapter from the server but the

If 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 riser card.

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

Problem determination tips

Due to the variety of hardware and software combinations that can be encountered, use the following information to assist you in problem determination. If possible, have this information available when requesting assistance from Service Support and Engineering functions.

v Machine type and model

v Microprocessor or hard disk upgrades

v Failure symptom

– Do diagnostics fail?

– What, when, where, single, or multiple systems?

– Is the failure repeatable?

– Has this configuration ever worked?

– If it has been working, what changes were made prior to it failing?

– Is this the original reported failure?

Diagnostics version

– Type and version level

Hardware configuration

– Print (print screen) configuration currently in use

– BIOS level

Operating system software

– Type and version level

Note: To eliminate confusion, identical systems are considered identical only if

they:

1. Are the exact machine type and models

2. Have the same BIOS level

3. Have the same adapters/attachments in the same locations

4. Have the same address jumpers/terminators/cabling

5. Have the same software versions and levels

Chapter 2. Diagnostics 77

6. Have the same diagnostics code (version)

7. Have the same configuration options set in the system

When you call for service, have as much of the following information available as possible:

v Machine type and model

v Microprocessor and hard disk drive upgrades

v Failure symptoms

– Does the server fail the diagnostic programs? If so, what are the error codes?

– What occurs? When? Where?

– Is the failure repeatable?

– Has the current server configuration ever worked?

– What changes, if any, were made before it failed?

– Is this the original reported failure, or has this failure been reported before?
