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:
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 “Power
cords” on page 93.
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, 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 x3550 Type 7978 and 1913: 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
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.

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 159 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 43.
v Light path diagnostics
Use the light path diagnostics to diagnose system errors quickly. See “Light path diagnostics” on page 56 for more information.
v Diagnostic programs, messages, and error messages
The diagnostic programs, which are stored in upgradeable read-only memory (ROM) on the system board, are the primary method of testing the major components of the server. See “Diagnostic programs, messages, and error codes” on page 61 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 detects a problem, one or more beeps 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 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, and pause, and three short beeps. A beep code indicates that POST has detected a problem.
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 48 for information about diagnosing microprocessor problems.

Error logs
The POST error log contains the three most recent error codes and messages that were generated during POST. The BMC log contains messages that were generated by the BMC. The system event/error log is a combined log that contains messages that were generated during POST and all system status messages from the service processor (BMC).
The system event/error log and BMC System Event log are limited in size. When each log is full, new entries will not overwrite existing entries; therefore, you must periodically clear these logs through the Configuration/Setup Utility program (the menu choices are described in the User’s Guide on the IBM System x
Documentation CD). When you are troubleshooting an error, be sure to clear both
the logs so that you can find current errors more easily.
Important: After you complete a repair or correct an error, clear the BMC log to
turn off the system-error LED on the front of the server.
Entries that are written to the system event/error 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.
You can view the contents of the POST error log, the system event log, and the system event/error log from the Configuration/Setup Utility program.
When you are troubleshooting PCI-X/PCI Express slots, note that the error logs report the PCI-X/PCI Express 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 on the IBM System x
Documentation CD for more information).
Viewing error logs from the Configuration/Setup Utility program
For complete information about using the Configuration/Setup Utility program, see the User’s Guide on the IBM System x Documentation CD.
To view the error logs, complete the following steps:
1. Turn on the server.
2. When the prompt Press F1 for Setup appears, press F1. If you have set both a
power-on password and an administrator password, you must type the administrator password to view the error logs.
3. Use one of the following procedures:
v To view the POST error log, select Event/Error Logs, and then select POST
Error Log.
v To view the BMC system event log, select Advanced Setup --> Baseboard

Checkout procedure
The checkout procedure is the sequence of tasks that you must 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 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 48 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 43 and “Solving undetermined problems” on page 86.
v For information about power-supply problems, see “Solving power problems” on
page 84.
v For intermittent problems, check the error log; see “Error logs” on page 26 and
“Diagnostic programs, messages, and error codes” on page 61.

Video problems
See “Monitor problems” on page 49.
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 “Safety” on page vii and “Handling static-sensitive devices” on page 96.
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 log or in the system-error log.
v If the system-error LED is lit, it indicates that an error has occurred; go to
step 2 on page 57.
The following illustration shows the operator information panel.

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 58 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.
The following illustration shows the LEDs on the system board.

Remind button
You can use the remind button on the light path diagnostics panel to put the system-error LED on the operator information panel into Remind mode. When you press the remind button, you acknowledge the error but indicate that you will not take immediate action. The system-error LED flashes while it is in Remind mode and stays in Remind mode until one of the following conditions occurs:
v All known errors are corrected.
v The server is restarted.
v A new error occurs, causing the system-error LED to be lit again.
Light path diagnostics switch
The light path diagnostics switch allows you to review error indications after the server has been powered down. Press and hold the diagnostics switch, located on the system board to relight the LEDs that were lit before you removed power from the server. The LEDs will remain lit for as long as you press the switch, to a maximum of 25 seconds.

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 64.
Chapter 2. Diagnostics 61
Running the diagnostic programs
To run the diagnostic programs, complete the following steps:
1. Turn off the server and any peripheral devices.
2. Turn on all attached devices; then, turn on the server.
3. When the prompt F2 for Diagnostics appears, press F2.
Note: To run the diagnostic programs, you must start the server with the
highest level password that is set. That is, if an administrator password is set, you must enter the administrator password, not the user password, to run the diagnostic programs.
4. Type the applicable password; then, press Enter.
5. Select either Extended or Basic from the top of the screen.
6. From the diagnostic programs screen, select the test that you want to run, and follow the instructions on the screen.
You can press F1 while running the diagnostic programs to obtain help information. 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 and return to where you left off, press Esc.
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 you run the diagnostic programs with no mouse attached to the server, you will not be able to navigate between test categories using the Next Cat and Prev Cat buttons. All other functions provided by mouse-selectable buttons are also available using the function keys.
You can test the USB keyboard by using the regular keyboard test. The regular mouse test can test a USB mouse. Also, you can run the USB interface test only if there are no USB devices attached.
You can view server configuration information (such as system configuration, memory contents, interrupt request (IRQ) use, direct memory access (DMA) use, device drivers, and so on) by selecting Hardware Info from the top of the screen.
When you are diagnosing hard disk drives, select SCSI Attached Disks for the most thorough test. Select Fixed Disks for any of the following situations:
v You want to run a faster test.
v The server contains RAID arrays.
v The server contains simple-swap SATA hard disk drives.
determine what action you should take as a result of a diagnostic text message
To or error code, see the table in “Diagnostic error codes” on page 64.
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.
62 IBM System x3550 Type 7978 and 1913: Problem Determination and Service Guide
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 48 for information about diagnosing microprocessor problems.
If the server stops during testing and you cannot continue, restart the server and try running the diagnostic programs again. If the problem remains, replace the component that was being tested when the server stopped.
Diagnostic text messages
Diagnostic text messages are displayed while the tests are running. A diagnostic text message contains one of the following results:
Passed: The test was completed without any errors.
Failed: The test detected an error.
User Aborted: Yo u stopped the test before it was completed.
Not Applicable: Yo u 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 summary test log is displayed. To view the detailed test log, press the Ta b key while viewing the summary 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 you turn it on.
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.
Chapter 2. Diagnostics 63
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.
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/support.
2. In the Search technical support box, enter x3550 bios
3. Download the latest BIOS code update.
4. 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 98 for more information.
3. Locate the boot block recovery jumper block (J14) on the system board.

System-error log messages
A system-error log is generated only if a Remote Supervisor Adapter II SlimLine is installed. The system-error log can contain messages of three types:
Message 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 BMC service processor).
Note: The BMC 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-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:

The following table describes the possible system-error log messages and suggested actions to correct the detected problems.
Note: These actions have the following meaning:
Reseat the power supply
Complete the following steps:
1. Remove the power supply from the server.
2. Check the power supply for damage and for damaged connectors.
3. Install the power supply in the server (see “Installing a power supply” on page 121).
Reseat the microprocessor
Complete the following steps:
1. Remove the heatsink and the microprocessor from the server using a vacuum tool (see “Removing a microprocessor” on page 137).
2. Visually inspect the microprocessor and the microprocessor socket for damage.
3. Reinstall the microprocessor and the heatsink in the server, taking special care that the layer of thermal grease is intact (see “Installing a microprocessor” on page 138).
Attention: If the layer of thermal grease is disturbed, the
microprocessor could overheat and be damaged.
