Server controls, LEDs, and power

This section describes the controls and light-emitting diodes (LEDs) and how to turn the server on and off.

Front view

The following illustration shows the controls, LEDs, and connectors on the front of the server.

USB port: You can connect a USB device to this connector.

Operator information panel: This panel contains controls, indicators, and a USB port. Swing it open to see the light path diagnostics LEDs on the side surface. Details about the operator information panel are listed below.

Operator information panel
Power-control button:	Press this button to turn the server on and off manually. A power-control-button shield comes with your server. You can install this disk-shaped shield to prevent the server from being turned off accidentally.
Power-on LED: When this LED is lit and not flashing, it indicates that the server is turned on. When this LED is flashing, it indicates that the server is turned off and still connected to an ac power source. When this LED is off, it indicates that ac power is not present, or the power supply or the LED itself has failed. A power LED is also on the rear of the server.Note: If this LED is off, it does not mean that there is no electrical power in the server. The LED might be burned out. To remove all electrical power from the server, you must disconnect the power cord from the electrical outlet.Reset button: Press this	button to reset the server and run the power-on self-test (POST). You might have to use a pen or the end of a straightened paper clip to press the button.
System-error LED: When	this LED is lit, it indicates that a system error has occurred.An LED on the diagnostic LED panel on the side of the operator information panel is also lit to help isolate the error (see “Light path diagnostics” on page 18).
USB connector: You can	connect a USB device to this connector.
Release latch: Press this	latch to release the operator information panel to access the light path diagnostics LED panel.
Information LED: When	this LED is lit, it indicates that a noncritical event has occurred (see “Light path diagnostics” on page 18).
Locator LED: Use this blue	LED to visually locate the server if it is in a location with numerous other servers. A locator LED is also on the rear of the server. You can use the Management Processor Assistant (MPA) in IBM Director to cause this LED to be lit, off, or flashing (see the User’sGuideon the IBM xSeriesDocumentationCD for more information). If the server is connected to an RXE-100 Remote Expansion Enclosure, pressing the Locate button on the enclosure causes this LED to be lit.Note: This LED flashes while the server is being turned on or restarted, and turns off when POST is complete.
SCSI activity LED: When	this LED is lit, it indicates that there is activity on the SCSI bus.

CD-ROM drive activity LED: When this LED is lit, it indicates that the CD-ROM drive is in use.

Diskette drive activity LED: When this LED is lit, it indicates that the diskette drive is in use.

Hard disk drive activity LED: When this LED is flashing, it indicates that the associated hard disk drive is in use.

Hard disk drive status LED: When this LED is lit continuously, it indicates that the associated hard disk drive has failed. The interpretation of a flashing status LED depends on the SCSI controller that is connected to the hot-swap drive, as follows:

- When the drive is connected to the integrated SCSI controller with RAID capabilities, a flashing status LED indicates that the drive is a secondary drive in a mirrored pair and the drive is being synchronized.

- When the drive is connected to an optional ServeRAID controller, a slowly flashing (one flash per second) status LED indicates that the drive is being rebuilt. When the LED is flashing rapidly (three flashes per second), it indicates that the controller is identifying the drive.

Hard disk drive filler panels: A filler panel and air baffle is used to cover empty hard disk drive bays. A filler panel and air baffle must be installed in each empty bay to ensure proper system cooling. Your server comes with five filler panels and air baffles installed, and one completely empty bay.

Rear view

The following illustration shows the LEDs on the rear of the server.

AC power LED: Each hot-swap power supply has an ac power LED that is visible from the rear of the server. The power supply also has an ac power LED and a dc power LED on the top of the power supply, visible when the server cover is removed. When the ac power LED is lit, ac input to the power module is present and within specifications. During typical operation, both the ac and dc power LEDs on the top of the power supply are lit. For any other combination of LEDs, see "Power LED errors" on page 130.

Ethernet link LEDs: When these LEDs (one for the Remote Supervisor Adapter II, two for the network) are lit, they indicate that the related Ethernet link is operational.

Remote Supervisor Adapter II activity LED: When this LED is flashing, the Remote Supervisor Adapter II is functioning normally. When the LED is lit continuously, there is a problem with the Remote Supervisor Adapter II. When the LED is off, the Remote Supervisor Adapter II is not functioning.

Remote Supervisor Adapter II power LED: When this LED is lit, it indicates that power is being supplied to the Remote Supervisor Adapter II.

Attention LED: When this LED is on steady, it indicates that the adapter in the corresponding slot is ready to be removed (hot-pluggable adapter only) or there is a problem with the adapter. When this LED is flashing, it indicates that an operation is in progress or that the adapter requires attention, depending on the operating system.

Locator LED: Use this blue LED to visually locate the server if it is in a location with numerous other servers. A locator LED is also on the operation information panel on the front of the server. You can use the Management Processor Assistant (MPA) in IBM Director to cause this LED to be lit, off, or flashing (see the User's Guideon the IBM xSeriesDocumentationCD for more information on IBM Director). If the server is connected to an RXE-100 Remote Expansion Enclosure, pressing the Locate button on the enclosure causes this LED to be lit.

Note: This LED flashes while the server is being turned on or restarted, and turns off when POST is complete.

Ethernet activity LEDs: When these LEDs (one for the Remote Supervisor Adapter II, two for the network) are lit, they indicate that activity is taking place on the related network.

The following illustration shows the connectors on the rear of the server.

Remote Supervisor Adapter II ASM connector: Attach an ASM breakout cable to this connector to enable system management through the serial connectors and through the ASM RS-485 connectors.

Remote Supervisor Adapter II USB connector: This connector is not available for use.

Remote Supervisor Adapter II Ethernet connector: Use this connector to connect the Remote Supervisor Adapter II to a network to manage the server from a remote location.

To enable remote server management through a network, use the Remote Supervisor Adapter II Ethernet port. To enable remote server management using a modem, use the Remote Supervisor Adapter II serial connector on the breakout cable. To connect the server with another server, use the Remote Supervisor Adapter II ASM interconnect connector.

Remote Supervisor Adapter II video connector: Connect the server monitor to this connector.

Note: The external power connection on the Remote Supervisor Adapter II is not supported on the xSeries 365 server.

Ethernet connectors: Use these connectors to connect the server to a network.

USB connectors: Connect USB devices to these connectors.

RXE Expansion port: Use this connector to connect the server to a remote I/O enclosure. This port enables the exchange of data between the server and the enclosure (see "RXE Expansion Port connector" on page 64).

The server comes with one or two hot-swap power supplies, depending on the configuration. You can add a second hot-swap power supply to obtain full power redundancy. Connect each power supply to an ac power source for power redundancy.

SCSI connector: Connect an external SCSI device to this connector.

Light path diagnostics LED panel

Swing the operator information panel out to see the light path diagnostics LED panel on the side surface (see "Light path diagnostics" on page 18 and "Light path LED errors" on page 93).

Server power features

When the server is connected to an ac power source but is not turned on, the operating system does not run, and all core logic except for the service processor is shut down; however, the server can respond to requests from the service processor, such as a remote request to turn on the server. The power-on LED flashes to indicate that the server is connected to ac power but not turned on.

Turning on the server

Approximately 20 seconds after the server is connected to ac power, the power-control button becomes active, and you can turn on the server and start the operating system by pressing the power-control button.

The server can also be turned on in any of the following ways:

• If a power failure occurs while the server is turned on, the server will restart automatically when power is restored.
• If the server is connected to an Advanced System Management interconnect network that contains at least one server with a Remote Supervisor Adapter or Remote Supervisor Adapter II installed, the server can be turned on from the Remote Supervisor Adapter or Remote Supervisor Adapter II user interface.
• The system-management software for the Remote Supervisor Adapter II in your server can turn on the server.
• If your operating system supports the Wake on LAN feature, the Wake on LAN feature can turn on the server.

Note: When 4 GB or more of memory (physical or logical) is installed, some memory is reserved for various system resources and is unavailable to the operating system. The amount of memory that is reserved for system resources depends on the operating system, the configuration of the server, and the configured PCI options.

Turning off the server

When you turn off the server and leave it connected to ac power, the server can respond to requests from the service processor, such as a remote request to turn on the server. To remove all power from the server, you must disconnect it from the power source.

Note: Under some conditions, the two rear fans in front of the power supplies will be operating when the server is turned off and connected to ac power. This enables the power supplies to be cooled when they are generating power for standby functions.

Some operating systems require an orderly shutdown before you turn off the server. See your operating-system documentation for information about shutting down the operating system.

Statement 5

CAUTION:

The power control button on the device and the power switch on the power supply do not turn off the electrical current supplied to the device. The device also might have more than one power cord. To remove all electrical current from the device, ensure that all power cords are disconnected from the power source.

Detailed information about the Configuration/Setup and Utility program is available in the User'sGuideon the IBM xSeriesDocumentationCD.

Using the ServerGuide Setup and Installation CD

The ServerGuideSetupandInstallationCD includes an easy-to-use setup and installation program that is designed for your IBM server. The ServerGuide program detects the server model and hardware options that are installed and uses that information during setup to configure the hardware. The ServerGuide program simplifies operating-system installations by providing updated device drivers and, in some cases, installing them automatically.

Note: The ServerGuide program works only with 32-bit Windows operating systems.

When you start the ServerGuideSetupandInstallationCD, the program prompts you to complete the following tasks:

• Select your language.
• Select your keyboard layout and country.
  •View the overview to learn about ServerGuide features.
• View the readme file to review installation tips for your operating system and adapter.
• Start the operating-system installation. You will need your operating-system CD.

Detailed information about using ServerGuide is available in the User'sGuide on the IBM xSeriesDocumentationCD.

Using the PXE boot agent utility program

Use the Preboot Execution Environment (PXE) boot agent utility program to enable or disable operating-system wake-up support.

Note: The server does not support changing the network boot protocol or specifying the startup order of devices through the PXE boot agent utility program.

Complete the following steps to start the PXE boot agent utility program:

1. Turn on the server.
2. When the Broadcom NetXtreme Ethernet Boot Agent V6.1.3 prompt appears, press Ctrl+S. You have 2 seconds (by default) to press Ctrl+S after the prompt appears.

- Use the LSI Logic Configuration Utility program to:

- Perform a low-level format on a SCSI hard disk drive

– View or change SCSI IDs for attached devices

- Set SCSI protocol parameters on SCSI hard disk drives

• Use ServeRAID Manager to:

- Configure arrays

– View your RAID configuration and associated devices

– Monitor operation of your RAID controllers

Detailed information about using the RAID configuration programs is available in the User'sGuideon the IBM xSeriesDocumentationCD.

Updating the integrated service processor firmware

To update only the firmware for the Remote Supervisor Adapter II and the integrated service processor, download the firmware update package for the server from the IBM Support Web site at http://www.ibm.com/pc/support/ and follow the instructions in the text file on the Web site.

To update the server BIOS, device drivers, and other firmware including the firmware for the Remote Supervisor Adapter II and integrated service processor, download and apply the system service package for the server. Detailed information is available in the User'sGuideon the IBM xSeriesDocumentationCD.

Configuring the Gigabit Ethernet controllers

The Ethernet controllers are integrated on the I/O board. They provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in your server support auto-negotiation, the controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operate at that rate and mode.

You do not need to set any jumpers or configure the controllers. However, you must install a device driver to enable the operating system to address the controllers. For device drivers and information about configuring the Ethernet controllers, see the BroadcomNetXtremeGigabitEthernetSoftwareCDthat comes with your server. For updated information about configuring the controllers, go to http://www.ibm.com/pc/support/.

Remote Supervisor Adapter II

The Remote Supervisor Adapter II can be used on an Advanced System Management (ASM) network so that you can manage the server remotely.

For more information about how to configure and use an ASM network to manage the server remotely through the Web-based interface or the text-based interface, see the User's Guide and the IBM Remote Supervisor Adapter II User's Guide, both of which can be found on the IBM xSeriesDocumentationCD.

Chapter 3. Diagnostics

This chapter provides basic troubleshooting information to help solve some common problems that might occur with 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 145 for more information.

General checkout

Follow the checkout procedure for diagnosing hardware problems. Review the following information before performing the checkout procedure:

- Read the safety information beginning on page 147.

•The diagnostics programs provide the primary methods of testing the major components of the server, including the I/O board, Ethernet controller, RAM, keyboard, mouse (pointing device), serial ports, hard disk drives, and parallel port. You can also use them to test some external devices. If you are not sure whether a problem is caused by the hardware or by the software, you can use the diagnostics programs to confirm that the hardware is working correctly. The diagnostic programs (see "Starting the diagnostic programs" on page 23) are in the system flash erasable programmable read-only memory (EPROM) on the I/O board.

- When you run the diagnostics programs, a single problem might cause several error messages. If you receive several error messages, correct the cause of the first error message. The other error messages might not occur the next time you run the diagnostics programs.

- Before running the diagnostics 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 you suspect that it is part of a cluster, you can run all diagnostics 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:

– The customer identifies the failing server as part of a cluster.

- 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:

1. When testing a server that is part of a shared hard disk drive cluster, run only one test at a time, in looped mode. Do not run all tests in looped mode, because the hard disk drive tests might run.

2. If more than one error code is displayed, correct the first error. The other error codes might not occur the next time you run the diagnostics programs.

3. If the server is suspended and a POST error code is displayed, see "POST error logs" on page 17.

4. If the server is suspended and no error message is displayed, see "Error symptoms" on page 121 and "Undetermined problems" on page 136.

5. For information about power-supply problems, see "Power checkout" on page 27.

6. For intermittent problems, check the error log; see "POST error logs" on page 17 and "Diagnostic programs and error messages" on page 22.

Complete the following steps to perform the checkout procedure:

001 IS THE SERVER PART OF A CLUSTER?

YES. Schedule maintenance for the server. Shut down all servers related to the cluster. Run the storage test.

NO. Go to step 002.

002 IF THE SYSTEM IS NOT PART OF A CLUSTER:

If the operating system is running, complete the following steps:

1. Check the light path (see "Light path diagnostics" on page 18).

2. Check the service processor system-error logs:

a. If the system-error log indicates a damaged field replaceable unit (FRU), replace the FRU, and run diagnostics to confirm that the problem has been solved.

b. If the system-error log does not indicate a damaged FRU, see "Error symptoms" on page 121 and "Undetermined problems" on page 136

If the operating system is not running, complete the following steps:

1. Check the light path (see "Light path diagnostics" on page 18).

2. Check the service processor system-error logs.

a. If the error log indicates a damaged field replaceable unit (FRU), replace the FRU, and run diagnostics to confirm that the problem has been solved.

b. If the error log does not indicate a damaged FRU, check the operating-system event logs; if these logs do not specify a particular error, go to step 3.

1. Turn off the server and all external devices.

2. Check all cables and power cords.

3. Set all display controls to the middle position.

4. Turn on all external devices.

5. Turn on the server.

6. Watch the screen and the serial port for POST errors, and record any POST error messages that are displayed on the screen. If an error is displayed, look up the first error (see "POST error codes" on page 88).

7. Run diagnostics (see "Starting the diagnostic programs" on page 23).

003 DID THE DIAGNOSTIC PROGRAM START?

NO. Find the failure symptom in "Error symptoms" on page 121.

YES. Run the diagnostic programs. If necessary, see “Diagnostic programs and error messages” on page 22.

If you receive an error, see Chapter 6, "Symptom-to-FRU index," on page 85

If the diagnostic programs were completed successfully and you still suspect a problem, see "Undetermined problems" on page 136.

If the server does not turn on, see "Error symptoms" on page 121.

Diagnostic tools overview

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

- 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 error logs” for more information.

•Light path diagnostics feature

Use the light path diagnostics feature to identify system errors quickly. See “light path diagnostics” on page 18 for more information.

•Diagnostic programs and error messages

The diagnostic programs are stored in the system flash EPROM on the I/O board. These programs are the primary method of testing the major components of the server. See "Diagnostic programs and error messages" on page 22 for more information.

POST error logs

When you turn on the server, it performs a series of tests to check the operation of server components and some of the options installed in the server. This series of tests is called the power-on self-test, or POST.

If POST finishes without detecting any problems, a single beep sounds, and the first screen of the operating system opens or an application program starts.

If POST detects a problem, more than one beep might sound, or an error message appears on the screen. See “Beep symptoms” on page 86 and “POST error codes” on page 88 for more information.

Notes:

1. If a power-on password is set, you must type the password and press Enter, when prompted, before POST will continue.
2. 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.

The POST error log contains the three most recent error codes and messages that were generated during POST. The system-error log contains all messages that were generated during POST and all system status messages from the service processor.

You can view the contents of the system-error log from the Configuration/Setup Utility program or from the diagnostic programs.

Note: When troubleshooting PCI-X slots, you will notice that the error logs report the PCI-X buses numerically. The numerical assignment will change depending on your configuration.

Viewing error logs from the Configuration/Setup Utility program

Start the Configuration/Setup Utility program; then, select Error Logs from the main menu. See "Using the Configuration/Setup Utility program" on page 11 for more information.

Viewing error logs from the diagnostic programs

Start the diagnostic programs; select Hardware Info from the top of the diagnostic programs screen; select System Error Log from the list that appears; then, follow the instructions on the screen. See 'Starting the diagnostic programs' on page 23 for more information.

Light path diagnostics

Many errors are first indicated by the illumination of the information LED or system-error LED in the operator information panel on the front of the server. If one or both of these lights are lit, one or more lights elsewhere in the server might also be lit and can direct you to the source of the error.

This light path diagnostics feature provides a path that you can follow in three phases to help identify the source of an error. The lights are designed to be followed in an orderly progression, depending on the error.

Note: Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30.

The lights are viewed in the following order:

1. Begin on the front panel by checking the operator information panel.

2. The information LED indicates that information concerning a sub-optimal condition in the server is available in the system-error log.

3. The system-error LED indicates that an error has occurred.

If the system-error LED on this panel is lit, go to step 2.

Note: The LEDs and connectors on the operator information panel are described in "Front view" on page 4.

1. Open the operator information panel by pressing the release latch to swing the panel out and reveal the light path diagnostics panel. Lit LEDs on this panel indicate the type of error that has occurred.

Then, check the system service label. This label gives an overview of internal components that correspond to the LEDs on the light path diagnostics panel. This information, combined with the information in the table "Light path LED errors" on page 93, can often provide enough information to correct the indicated error.

1. Look inside the server, if necessary. Certain components inside the server have LEDs that will be lit to indicate the location of a problem. For example, a VRM error will light the LED next to the failing VRM on the microprocessor tray assembly.

Light path diagnostics LEDs for DIMMs and fans must be viewed from inside the server and will not be lit unless the serv.er is connected to a power source, although the server does not have to be turned on to view these LED. The LEDs for microprocessors and VRMs are viewed by removing the microprocessor-tray assembly. The following sections describe the procedures to follow to view the LEDs on the microprocessor-tray assembly and memory board.

Microprocessor LEDs

Complete the following steps to view the microprocessor LEDs:

1. Turn off the server and any peripheral devices; then, disconnect all external cables from the server.
2. Slide the server out of the rack cabinet.
3. Remove the fans (see "Replacing a hot-swap fan" on page 55) and memory cassette (see step 4 on page 46).
4. Remove the microprocessor tray:

a. Lift the microprocessor-tray release latch (see "Installing a microprocessor" on page 44).
b. Open the microprocessor-tray levers.
c. Pull out the microprocessor tray.

1. Press and hold down the light-path diagnostics button on the microprocessor board. The LEDs will be lit while the button is pressed. You can light the LEDs for a maximum of 2 minutes, after which power is no longer available for the LEDs.

Note: You can press the light-path diagnostics button to relight the light path diagnostics LEDs that are lit on the microprocessor tray without ac

power. After ac power has been removed from the server, power remains available to these LEDs for up to 12 hours. After 12 hours, you must reinstall the microprocessor tray and turn on the server to supply power to the LEDs.

To reinstall the microprocessor tray, reverse the preceding steps.

DIMM LEDs

Complete the following steps to view the DIMM LEDs:

Note: The lit LEDs light the connector retaining clips; look for a lit retaining clip to locate a failed DIMM.

1. Turn off the server and all peripheral devices.
2. Slide the server out of the rack cabinet.
3. Open the top cover.

a. The following illustration shows the internal connectors and LEDs on the 8-DIMM-connector memory board in the memory cassette.

b. The following illustration shows the internal connectors and LEDs on the 16-DIMM-connector memory board in the memory cassette.

1. If necessary, open the DIMM access doors on the memory cassette to view the DIMM LEDs.

Remind button

You can use the remind button to place the system-error LED on the front panel into the remind mode (flashes every 2 seconds). By pressing this button, you acknowledge the failure but indicate that you will not take immediate action. If a new failure occurs, the system-error LED is lit again.

The system-error LED stays in remind mode until one of the following conditions occurs:

• All known problems are solved.
  •The server is restarted.

•A new problem occurs.

You can use the remind button to delay server maintenance until a later time.

Diagnostic programs and error messages

The diagnostic programs are in the system flash erasable programmable read-only memory (EPROM) on the I/O board. These programs are the primary method of testing the major components of the server.

Diagnostic error messages indicate that a problem exists; they are not intended to be used to identify a failing part. Troubleshooting and servicing of complex problems that are indicated by error messages should be performed by trained service personnel.

Sometimes the first error to occur causes additional errors. In this case, the server displays more than one error message. Always follow the suggested action instructions for the firsterror message that appears.

Diagnostic text messages

While a test is running, the name of the test is displayed on the screen. If the test detects an error or is abnormally ended, a message is displayed to indicate the reason that the test stopped. The message is in the following form:

resulttest_specific_string

where:

resultis one of the following results:

Passed

This test was completed without any errors.

Failed

This test discovered 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

A possible problem was reported during the test (for example, a device that was to be tested is not installed).

testspecificstring

is an error code or other information about the error.

Starting the diagnostic programs

This section describes the general procedure to run the diagnostic programs.

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 help, press Esc.

Complete the following steps to start the diagnostic programs:

1. Turn on the server and watch the screen.

2. When the message Press F1 for Configuration/Setup, Press F2 for Diagnostics appears, press F2.
   If a power-on password is set, the server prompts you for it. Type the power-on password, and press Enter.

3. When the Diagnostic Programs screen appears, select either Extended or Basic from the top of the screen.

4. Select the test you want to run from the list that appears; then, follow the instructions on the screen.

Notes:

a. 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.
b. The keyboard and mouse (pointing device) tests assume that a keyboard and mouse are attached to the server.
c. 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.
d. You can test the USB keyboard by using the regular keyboard test. The regular mouse test can test a USB mouse. You can run the USB interface test only if there are no USB devices attached.
e. 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.

If the diagnostic programs do not detect any hardware error 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 the software package.

Diagnostic error codes are listed in "Diagnostic error codes" on page 95.

Viewing the test log

When the tests are completed, you can view the test log by selecting Utility from the top of the screen and then selecting View Test Log.

Notes:

1. You can view the test log only while you are in the diagnostic programs. When you exit the diagnostic programs, the test log is cleared (saved test logs are not affected). To save the test log so that you can view it later, click Save Log on the diagnostic programs screen and specify a location and name for the saved log file.

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 may contain other data.

Viewing the system-error log

You can also view the system-error log from the diagnostic programs. See the instructions in "POST error logs" on page 17.

Recovering BIOS code

If the BIOS code in the server has become damaged, such as from a power failure during a flash update, you can recover the BIOS using the recovery boot block and a BIOS flash diskette. You can download a BIOS flash diskette from http://www.ibm.com/pc/support/.

The flash memory of the server consists of a primary page and a backup page. The J19 jumper on the I/O board controls which page is used to start the server. If the BIOS code in the primary page is damaged, you can use the backup page to start the server; then start the BIOS flash diskette to restore the BIOS code to the primary page.

To recover the BIOS code, complete the following steps:

1. Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30.
2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover.

1. Locate the boot block recovery jumper (J19 on the I/O board).
2. Move J19 to pins 2 and 3 to enable secondary boot block page.
3. Insert the BIOS flash diskette into the diskette drive.

4. Restart the server.

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

6. When you are asked whether you want to move the current POST/BIOS image to the backup ROM location, type N.
   Attention: Typing Y will copy the damaged BIOS code into the secondary page.
7. When you are asked whether you would like to save the current code to a diskette, select N.
8. Type 1 and press Enter to continue.

Attention: Do not restart or power off the server until the update is completed.

1. Turn off the server.
2. Move jumper J19 back to pins 1 and 2 to return to normal startup mode.
3. Replace the cover; then, restart the server.

Password override jumper

Change the position of the password override jumper by using the following procedure:

1. Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30.

2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove the cover.

1. Locate the power-on password override jumper (J20), removing any components that impede access to the jumper.

Note: You might have to remove the Remote Supervisor Adapter II to access the jumper.

1. Move the jumper from pins 1 and 2 (default) to pins 2 and 3.

2. Reinstall the cover and reconnect the external cables and power cords; then, turn on the server and access the Configuration/Setup Utility menu to change the power-on password.

3. Repeat steps 2 on page 25 and 3 on page 25; then, move the jumper back to pins 1 and 2.
4. Reinstall any components that were removed in step 3 on page 25; then, reinstall the cover and reconnect the external cables and power cord.

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

Attention: If an administrator password is set and then forgotten, it cannot be overridden or removed. You must replace the operator information panel.

Forcing a power-on

Complete the following steps to turn on the server without pressing the power-on button:

1. Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30.
2. Turn off the server and peripheral devices and disconnect all external cables and power cords; then, remove hot-swap fan number 2 (see "Replacing a hot-swap fan" on page 55).

1. Locate the force power-on jumper (J10), and place a jumper over the two pins.
2. Reinsert the microprocessor tray assembly fully into the server and reconnect the cables and power cords. The server will turn on.
3. To return the jumper to its default position, repeat step 2; then, remove the jumper from J10.
4. Reinsert the microprocessor tray assembly fully into the server and reconnect the cables and power cords.

Power checkout

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. A general procedure for troubleshooting power problems is as follows:

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 there is a loose screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and power connectors to all internal and external devices until the server is at the minimum configuration required to start the server (see "Minimum operating requirements" on page 136).
4. Reconnect all ac power cords and turn on the server. If the server starts up successfully, replace adapters and devices one at a time until the problem is isolated.

If the server does not start up from the minimal configuration, replace FRUs of minimal configuration one at a time until the problem is isolated.

To use this method, it is important to know the minimum configuration required for a system to start (see "Minimum operating requirements" on page 136). For specific problems, see "Power LED errors" on page 130.

Ethernet controller troubleshooting

The method of testing the Ethernet controller depends on which operating system is being used (see the Ethernet controller device driver readme file).

If the problem remains after you check the operating system documentation, try the following:

- Make sure that the Ethernet cable is installed correctly.

The network cable must be securely attached at all connections. If the cable is attached but the problem remains, try a different cable.

If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5 cabling.

If you directly connect two systems (without a hub), or if you are not using a hub with X ports, use a crossover cable.

Note: To determine whether a hub has an X port, check the port label. If the label contains an X, the hub has an X port.

- 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.

- Check the Ethernet controller LEDs on the server rear panel. These LEDs indicate whether a problem exists 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 loaded.

• Check the LAN activity LED on the rear of the server. The LAN activity LED is lit when data is active on the Ethernet network. If the LAN activity LED is off, make sure that the hub and network are operating and that the correct device drivers are loaded.
• Make sure that you are using the correct device drivers, which come with the server.
• Check for operating-system-specific causes for the problem.
• Make sure that the device drivers on the client and server are using the same protocol.

If the Ethernet controller still cannot connect to the network, inform the network administrator.

Chapter 4. Installing options

This chapter provides basic instructions for installing hardware options in your server. These instructions are intended for users who are experienced with setting up IBM server hardware.

Installation guidelines

Before you begin installing options in your server, read the following information:

- Read "Safety information" on page 147 and "Handling static-sensitive devices" on page 30. This information will help you work safely with your server and options.

- Make sure that you have an adequate number of properly grounded electrical outlets for your server, monitor, and other devices that you will connect to the server.

- Back up all important data before you make changes to disk drives.

- Have a small Phillips screwdriver available.

- Have a small flat-blade screwdriver available.

- You do not need to turn off the server to install or replace hot-swap power supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.

Attention: The Remote Supervisor Adapter II is not a hot-swap or hot-plug device.

•The orange color on components and labels identifies hot-swap or hot-plug components. You can install or remove hot-swap and hot-plug components while the server is running, provided that the server is configured to support this capability. See the instructions in this chapter for more information about removing and installing hot-swap and hot-plug components.

- The blue color on components and labels indicates touch points, where a component can be gripped, a latch moved, and so on.

- For a list of supported options for your server, go to http://www.ibm.com/pc/ compat/.

System reliability guidelines

To help ensure proper system cooling and system reliability, make sure that:

• Each of the drive bays has a drive or a filler panel and electromagnetic compatibility (EMC) shield installed in it.

- There is adequate space around the server to allow the server cooling system to work properly. See the documentation that comes with the rack.

- You have followed the cabling instructions that come with optional adapters.

- You have replaced a failed fan as soon as possible.

- You have replaced a hot-swap drive within 2 minutes of removal.

- Microprocessor sockets 2, 3, and 4 each contain either a microprocessor baffle or a microprocessor and heat sink at all times.

- You do not operate the server without the cover for more than two minutes.

Working inside a server with power on

Your server supports hot-swap devices and is designed to operate safely while it is turned on and the cover is removed. Follow these guidelines when you work inside a server that is turned on:

- Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts before working inside the server; do not wear cuff links while you are working inside the server.

- Do not allow your necktie or scarf to hang inside the server.

- Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist watches.

- Remove items from your shirt pocket, such as pens and pencils, that could fall into the server as you lean over it.

- Avoid dropping any metallic objects, such as paper clips, hairpins, and screws, into the server.

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices, including your server. 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:

- Limit your movement. Movement can cause static electricity to build up around you.

- Handle the device carefully, holding it by its edges or its frame.

- Do not touch solder joints, pins, or exposed circuitry.

- Do not leave the device where others can handle and damage it.

- While the device is still in its static-protective package, touch it to an unpainted metal part of the server for at least 2 seconds. This drains static electricity from the package and from your body.

- Remove the device from its package and install it directly into the 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 your server cover or on a metal surface.

•Take additional care when handling devices during cold weather. Heating reduces indoor humidity and increases static electricity.

Major components of the xSeries 365 server

The following illustration shows the major components of the xSeries 365 server.

The orange color on components and labels in the server identifies hot-swap or hot-plug components. You can install or remove these components while the system is running, provided that the server is configured to support this function.

The blue color on components and labels indicates touch points where a component can be gripped, a latch moved, and so on.

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

Removing the cover and bezel

Complete the following steps to remove the cover and bezel:

1. Read "Safety information" on page 14/ and "Installation guidelines" on page 29.

PCI or PCI-X adapters

The following notes describe the types of adapters that your server supports and other information that you must consider when installing a PCI or PCI-X adapter:

•The server supports 3.3 V and universal PCI and PCI-X adapters; it does not support 5.0-V-only adapters.

•The following illustration shows the location and bus speeds of the PCI-X expansion slots on the I/O board.

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

•Each PCI/PCI-X slot is on a separate PCI bus.

Slot number PCI Bus

1	0
2	3
3	6
4 F (15)
5 C (12)
6	9

- Slot 1 is a PCI slot and is dedicated to the Remote Supervisor Adapter II. The adapter will operate in PCI mode only. The bus speed is 33 MHz only. The adapter is non-hot-swappable; turn off the server when removing and installing the adapter.

- For slots 2 through 6, the bus speed will be set to the speed of the adapter; if a PCI adapter is installed, the bus will run in PCI mode.

- If you install a ServeRAID 6i adapter, it must be installed in slot 2.

- If you install an IXA adapter, it must be installed in slot 3.

- Locate the documentation that comes with the adapter and follow those instructions in addition to the instructions in this chapter.

- If you need to change switch settings or jumper settings on the adapter, follow the instructions that come with the adapter.

•The server scans devices and PCI-X slots to assign system resources in the following order: CD-ROM drive; disk drives; integrated Ethernet controller; integrated SCSI devices; and PCI-X slots 1, 2, 3, 4, 5, and 6. If an RXE-100 enclosure is attached to the server, the scan continues in sequence with PCI slots 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, and 18.

Note: You can use the Configuration/Setup Utility program to change the sequence and have the server scan one of the first six PCI slots before it scans the integrated devices. You cannot change the scan sequence of the PCI slots in an RXE-100 enclosure.

•The PCI-X slot numbers in an RXE-100 enclosure are assigned in the following order:

Slots in RXE-100 enclosure	Slot numbers assigned to A side	Slot numbers assigned to B side
6 slots on A side only 7 - 12* (A1 - A6)	none
6 slots on B side only none 7 - 12* (B1 - B6)
12 slots 7 - 12 (A1 - A6) 13 - 18 (B1 - B6)
* Both sides are numbered 7-12 when an RXE-100 enclosure is shared.

- If you install a RAID adapter other than a ServeRAID 6i adapter to control internal hot-swap hard disk drives, you might need to disconnect the internal channel cable from the SCSI RAID cable connector (J17) on the I/O board and connect it to the RAID adapter. No recabling is needed for a ServeRAID 6i adapter. See the information that comes with your RAID adapter.

- If you install a RAID adapter to control external hard disk drives, connect one end of the RAID external channel cable (separately orderable) to an external channel connector on the edge of the RAID adapter that is accessible from the rear of the server; then, route the cable to the external SCSI device and connect it to the applicable connector.

Note: See the documentation that comes with the RAID adapter for any additional cabling instructions. That documentation also provides information about installing the RAID software and configuring the RAID adapter. For a list of supported RAID adapters, go to http://www.ibm.com/pc/us/compat/.

- Before attempting to install a new adapter, make sure that there is an available slot at the correct bus speed for it. If you need additional PCI-X slots, you can purchase a remote I/O expansion enclosure through your IBM marketing representative or authorized reseller.

Notes:

1. Before hot-swapping any PCI-X adapters, read the information in "Working inside a server with power on" on page 30.

2. For hot-pluggable adapters, make sure that the PCI hot-plug device driver is installed. For details, see the documentation that comes with the adapter.

Installing a hot-swap hard disk drive

The following notes describe the types of hard disk drives that your server supports and other information that you must consider when installing a hard disk drive:

•The server supports up to six 26 mm (1-inch), 3.5-inch, hot-swap hard disk drives in the hot-swap bays.
• Each hot-swap drive is in a tray, which has a green activity LED and an amber status LED in the upper-right corner. The activity LED flashes when the drive is active; the status LED is lit if the drive has an error. Each hot-swap drive has a single-connector-attached (SCA) connector, which connects directly into the hot-swap SCSI hard disk drive backplane. The backplane controls the SCSI IDs for the hot-swap drives.
- Before you install a hot-swap hard disk drive, take the following actions:

• Inspect the drive tray for any signs of damage.
• Make sure that the drive is installed in the tray correctly.
• If your server has an optional RAID adapter installed, see the documentation that comes with the adapter for information about installing a hard disk drive.

Complete the following steps to install a hard disk drive:

1. Read "Safety information" on page 147 and "Installation guidelines" on page 29.
2. Remove the filler panel and air baffle from one of the empty hot-swap bays, if present.

Attention: To maintain proper system cooling, do not operate the server for more than 10 minutes without either a drive or filler panel installed in each bay.

1. Install the hard disk drive in the hot-swap bay:

a. Make sure that the tray handle is open (that is, perpendicular to the front of the drive).

b. Align the drive assembly with the guide rails in the bay.

c. Gently push the drive assembly into the bay until the drive stops.

d. Push the tray handle to the closed (locked) position.

e. Check the hard disk drive status LED to make sure that the hard disk drive is operating correctly. If the amber hard disk drive status LED for a drive is lit continuously, that individual drive is faulty and needs to be replaced. If the green hard disk drive activity LED is flashing, the drive is being accessed.

1. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 58.

Note: If the server has a RAID controller or adapter installed, you might need to reconfigure the disk arrays after installing hard disk drives. See the documentation that comes with the adapter for more information.

Memory modules

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

- Your server supports 2.5 V, 184-pin, error correcting code (ECC), double-data rate (DDR) SDRAM, PC2100 registered DIMMs with Chipkill memory protection.

- DIMMs can be removed and replaced through the of the memory cassette.

- You can increase the amount of memory in the server by replacing the DIMMs with higher-capacity DIMMs or installing additional pairs of DIMMs in open sockets. The server supports 512 MB, 1 GB, and 2 GB DIMMs. See the ServerProven® list at http://www.ibm.com/pc/compat/ for an updated list of memory modules supported by the server.

- For a server with an 8-DIMM-connector memory cassette, you can increase the memory capabilities of your server by upgrading to the 16-connectormemory cassette. The 16-connector memory cassette supports memory mirroring and Memory ProteXion. See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory cassettes supported by the server. More information on Memory ProteXion and memory mirroring is available in the User'sGuideon the xSeriesDocumentationCD.

- The server uses interleaved DIMMs, which requires that you install DIMMs in specific configurations:

- In the 8-DIMM-connectormemorycassette, install DIMMs in pairs. Each pair must be of the same type, capacity, and speed. The DIMM connectors are arranged in two groups of four rows each; the server comes with one pair of DIMMs installed in DIMM connectors 1 and 5 in the memory cassette.

- In the 16-DIMMmemorycassette, the DIMM connectors are arranged in two groups of eight rows each. In non-mirrored mode, install DIMMs in pairs; in mirrored mode, install DIMMs in quads, or groups of 4. Each pair or quad must be of the same type, capacity, and speed.

- You must populate the DIMM connectors in the following order with the largest size first:

8-DIMM memory board

First pair DIMMs 1 and 5
Second pair DIMMs 2 and 6
Third pair DIMMs 3 and 7
Fourth pair DIMMs 4 and 8

16-DIMM memory board in non-mirrored mode

First pair DIMMs 1 and 3
Second pair DIMMs 14 and 16
Third pair DIMMs 2 and 4
Fourth pair DIMMs 13 and 15
Fifth pair DIMMs 5 and 7
Sixth pair DIMMs 10 and 12
Seventh pair DIMMs 6 and 8
Eighth pair DIMMs 9 and 11

16-DIMM memory board in mirrored mode

First quad DIMMs 1, 3, 14, and 16
Second quad DIMMs 2, 4, 13, and 15
Third quad DIMMs 5, 7, 10 and 12
Fourth quad DIMMs 6, 8, 9 and 11

Note: When memory mirroring is enabled, reported memory is reduced to half of installed memory.

Use the Configuration/Setup Utility program to enable or disable mirrored mode. More information about memory mirroring is available in the OptionInstallation Guideon the IBM xSeriesDocumentationCD.

DIMM banks and ports

The DIMMs constitute the following memory banks and use the following memory ports:

8-DIMM memory board

16-DIMM memory board

When you restart the server after adding or removing a pair or quad of DIMMs, the server displays a message that the memory configuration has changed.

DIMM installation

Complete the following steps to install DIMMs:

Note: Depending on the model, the memory cassette in your server might not have doors; this is normal. If the memory cassette has no doors, disregard any instructions to open or close the doors.

1. Read "Safety information" on page 147, "Installation guidelines" on page 29, and the documentation that comes with the DIMMs.
2. Turn off the server and peripheral devices, and disconnect the power cords and all external cables. Remove the top cover (see "Removing the cover and bezel" on page 32).

1. Insert the DIMM into the connector by aligning the edges of the DIMM with the slots at the ends of the DIMM connector. Firmly press the DIMM straight down into the connector by applying pressure on both ends of the DIMM simultaneously. The retaining clips snap into the locked position when the DIMM is firmly seated in the connector. If there is a gap between the DIMM and the retaining clips, the DIMM has not been correctly inserted; open the retaining clips, remove the DIMM, and then reinsert it.

2. Repeat steps 4 on page 42 through 7 for each additional DIMM that you install. Close the DIMM access doors when you have finished.

3. If you have other options to install or remove, do so now; otherwise, go to "Completing the installation" on page 58.

Installing a microprocessor

The following notes describe information that you must consider when installing a microprocessor in the server:

•The server comes with a minimum of one microprocessor installed on the microprocessor board in the microprocessor tray and supports up to four microprocessors. With more than one microprocessor, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load among the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications. The following illustration shows the microprocessor connectors and the microprocessor voltage regulator module (VRM) connectors on the microprocessor tray assembly.

Note: The voltage regulators for microprocessors 1 and 2 are integrated on the microprocessor tray assembly; the VRMs for microprocessors 3 and 4 come with the microprocessor options and must be installed on the microprocessor tray assembly.

- If one microprocessor is installed:

• The microprocessor is installed in microprocessor connector 1 (U22).
• The microprocessor supports both the startup and application processes.

- If you install additional microprocessors in the server, microprocessor 2 is installed in microprocessor connector 2 (U23); microprocessor 3 is installed in connector 3 (U24); microprocessor 4 is installed in connector 4 (U25).

• A new microprocessor comes in a kit with a VRM and a heat sink. The VRM is used only with microprocessor 3 or 4.
• Read the documentation that comes with the microprocessor to determine whether you need to update the server basic input/output system (BIOS) code. The most current level of BIOS code for the server is available from http://www.ibm.com/pc/support.

•To use SMP, obtain an SMP-capable operating system. For a list of supported operating systems, go to http://www.ibm.com/pc/compat/

Attention: To avoid damage and to ensure proper server operation, review the following information before you install a microprocessor:

- Make sure that the microprocessors are the same type, have the same cache size, and have the same clock speed.

- Make sure that the microprocessor internal and external clock frequencies are identical.

• See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of microprocessors that are supported by the server.

- When installing additional microprocessors, populate the microprocessor connectors in numeric order, starting with connector 2. If you install the microprocessors in the wrong order, the server will not turn on.

- Avoid touching the components and pins on the microprocessor. Ensure that the microprocessor is completely and correctly seated in the socket. Incomplete insertion might cause damage to the microprocessor board or to the microprocessor.

Complete the following steps to install a microprocessor:

1. Read "Safety information" on page 147 and "Installation guidelines" on page 29.

2. Turn off the server and all peripheral devices. Disconnect all power cords; then, disconnect all external signal cables from the server.

3. Remove the server cover and bezel (see "Removing the cover and bezel" on page 32).

1. Remove the memory cassette (see "Replacing the memory cassette" on page 56).

1. Remove all fans (see "Replacing a hot-swap fan" on page 55).
   

1. Remove the microprocessor tray:

a. Lift the microprocessor-tray release latch (1).
b. Open the microprocessor-tray levers (2).

Attention: The microprocessor tray is heavy. Pull the tray part-way out of the server, reposition your hands to grasp the body of the tray, and then pull the tray out the rest of the way.

c. Pull out the microprocessor tray (3).

Note: The new microprocessor comes in a kit with a VRM and a heat sink. The VRM is used only with microprocessors 3 and 4.

1. Remove the microprocessor baffle from the empty microprocessor socket and store the microprocessor baffle for future use.
2. Remove the protective cover, tape, or label from the surface of the microprocessor socket, if any is present.
3. Lift the microprocessor-release lever to the open position (135°).

Attention: You must ensure that the locking lever on the microprocessor socket is in the fully-open position before you insert the microprocessor in the socket. Failure to do so might result in permanent damage to the microprocessor, microprocessor socket, and microprocessor-tray assembly.

1. Install the microprocessor:

a. Touch the static-protective package containing the new microprocessor to any unpainted metal surface on the server; then, remove the microprocessor from the package.

b. Position the microprocessor over the microprocessor connector as shown in the following illustration. Carefully press the microprocessor into the socket.

Attention: To avoid bending the pins on the microprocessor, do not use excessive force when pressing it into the socket.

1. Close the microprocessor-release lever to secure the microprocessor.

Attention:

- Do not disturb or contaminate the thermal material on the bottom of the new heat sink. Doing so damages its heat-conducting capability and exposes the new microprocessor to overheating.

- 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 one captive screw fully before loosening the other captive screw helps break the bond between the components without damaging them.

1. Remove the heat sink from its package and remove the cover from the bottom of the heat sink. Make sure that the thermal material is still on the bottom of the heat sink. Remove the release liner and orient the heat sink above the microprocessor; then, press the heat sink into place. Press firmly on the captive screws and tighten them, alternating between screws until they are tight. Do not overtighten the screws.

2. If you installed microprocessor 3 or 4, install the VRM in the associated VRM socket.

a. Open the retaining clips at either end of the VRM connector.

Attention: To avoid breaking the VRM retaining clips or damaging the VRM connectors, open and close the clips gently.

b. Turn the VRM so that the VRM keys align correctly with the connector.
c. Insert the VRM into the connector. Firmly press the VRM straight down into the connector by applying pressure on both ends of the VRM simultaneously. The retaining clips snap into the locked position when the VRM is firmly seated in the connector. If there is a gap between the VRM and the retaining clips, the VRM has not been correctly inserted; open the retaining clips, remove the VRM, and then reinsert it.

1. Reinstall the microprocessor tray in the server.

a. Make sure the microprocessor-tray release latch is open; then, push the microprocessor tray into the server.

Attention: Before installing the microprocessor tray, fans must be removed from the server and the microprocessor-tray release latch must be open. Attempting to insert the microprocessor tray if any fans are installed or if the latch not fully open will result in damage to the microprocessor tray.

b. Close the tray levers and make sure they are securely latched.
c. Press the microprocessor tray release latch down.

1. If you are replacing the I/O board, remove the power backplane from the backerplate and position it on the new backerplate containing the replacement I/O board; then, attach it with the six screws that were removed in step 16.

Attention: Do not overtighten the screws.

1. Reinstall the I/O board and power backplane assembly by angling the front end of the assembly into the chassis first; then, gently slide it toward the front of the server while lowering the rear of the assembly into the chassis.

2. Align the two notches on each side of the assembly with the two metal loops on each side of the chassis.

3. Grasping the center flange, slide the assembly toward the rear of the server until it is in place.

4. Finger-tighten the two thumbscrews on the rear of the server.

Attention: Do not overtighten the screws.

1. Replace the power supply structure (see "Power-supply structure" on page 78).

2. Continue the reassembly procedure by following steps 1 on page 81 through 11 on page 82 in reverse order.

Notes:

a. Be sure to route the cables in between the fans, and then through the channel with the plastic lip.

b. The SCSI backplane cable and the external SCSI cables have similar connectors; be sure to reconnect them correctly.

c. The cable for the Remote Supervisor Adapter II must be routed over the top of the PCI adapter insulator located closest to the center of the server. Do not route the cable underneath this insulator.

d. Be sure to align the Remote Supervisor Adapter II cable correctly; the Remote Supervisor Adapter II is keyed to accept the cable in one direction only.

Notes:

1. Check the configuration before you replace a FRU. Configuration problems can cause false errors and symptoms.
2. For IBM devices not supported by this index, refer to the manual for that device.
3. Always start with "General checkout" on page 15.
4. Take the action (or replace the FRU) suggested first in the list of the right column, then restart the server to see if the problem has been corrected before taking further action.
5. Try reseating a suspected component or reconnecting a cable before replacing the component.

POST error codes and messages are displayed on the screen.

System-error log entries

The system-error log is similar to an event log and can contain messages of three major types:

Information Information messages do not require action and record significant system-level events. Example: 'System Complex Powered Up'

Warning Warning messages indicate possible problems but do not require immediate action. Example: 'System over recommended ambient temperature'

Error Error messages indicate system errors that may require attention. Example: 'Fan 2 not detected'

System-error log messages can originate from several sources.

-POST/BIOS

•SMI handler

•Service processor

Each entry contains date and time information, which is useful in determining the nature of the occurrence.

SMI handler messages

SMI handler is special system code that provides system monitoring functions.

When the SMI handler detects a microprocessor error, the SMI handler message identifies the affected processor using a ProcID number or an APICID number. The following table provides a cross reference between the physical microprocessor number, the ProcID and the APICID.

Physical Microprocessor Number 1	ProcID APICID
1 01 0000 or 0001
2 02 0002 or 0003
3 03 0004 or 0005
4 04 0006 or 0007
1 See “Microprocessor board connectors, jumpers and LEDs” on page 68 to find the physical microprocessor numbering

Following is an example of an SMI handler message:

Date/Time: 2002/05/08 03:35:30

DMI Type: 00

Source: SMI Hdlr

Error Code: 00150700 PERR: Slave signaled parity error

Error Code:

Error Data: Bus = 02, Slot = 01, VendID = 1014, DevID = 0302

Error Data:

This message indicates that a PCI Bus 02 parity error occurred at the recorded time. All of the SMI handler message codes are listed in the following table.

Note: The message codes in the following table do not include leading or trailing zeros.

Note: See Chapter 7, “Parts listing, Types 8861, 8862,” on page 139 to determine which components are replaceable by the customer and which components must be replaced by an IBM field service technician.

ServeRAID (ISPR) error procedures

Use the ISPR error procedures to help you solve ServeRAID problems. A complete list of error codes is listed in "ServeRAID error codes" on page 134.

Note: Where the ISPR error procedures refer to a hard disk drive backplane, see the chapter of this publication that concerns service replaceable units.

EF10 (Default ISPR)

1. No ISPR error present.

9ZXX through BZXX (SCSI bus error caused by cables, termination, defective drives, or similar problem)

1. Isolate between SCSI subsystem and controller by disconnecting all hard disk drive cables from suspect card, and restart.

Attention: Do not press F5. Doing so changes the server configuration.

If an ISPR error is still present, perform the following actions until the error is no longer present:

a. Reseat the controller

b. Replace the controller

Notes:

a. SCSI channel cable details, if any, appear elsewhere in this publication.
b. The adapter/controller detects a configuration change. Do not choose Save Changes. Instead, select F10 to bypass any options to this effect.

1. If ISPR error is EF10 after disconnecting cables:

a. Identify which channel is causing the error by the second digit (Z) of the original ISPR code as indicated in the following table.

Note: ServeRAID-4H controllers have 4 channels; ServeRAID-4L and -4Lx controllers have only one channel; and ServeRAID-4M and -4Mx

controllers have 2 channels. ServeRAID-5i controllers have no channels. The ServeRAID-5i uses the channel connectors of the onboard integrated SCSI controller.

SCSI channel code (z) Descriptions
1 Channel 1
2 Channel 2
3 Channel 1 and 2
4 Channel 3
5 Channel 1 and 3
6 Channel 2 and 3
7 Channel 1, 2, and 3
8 Channel 4
9 Channel 1 and 4
A Channel 2 and 4
B Channel 1, 2, and 4
C Channel 3 and 4
D Channel 1, 3, and 4
E Channel 2, 3, and 4
F Channel 1, 2, 3, and 4

b. Confirm that the channels identified from the error in step 2a on page 132 are the cause of the error by verifying that the error presents itself only when the offending channel is reconnected.

c. Check termination of identified channel.

Note: SCSI channel termination details, if any, appear elsewhere in this publication.

d. Check for proper backplane jumper configuration.

Note: SCSI channel jumper details, if any, appear elsewhere in this publication.

e. Check for proper cabling configuration in systems that use hard disk drive status cables. Reconnect all cables removed in step 1 on page 132.

f. Disconnect one drive at a time attached to the channel identified in step 2a on page 132, then, restart to determine which drive is causing the error.

g. Replace hard disk drive cable.

h. Replace hard disk drive backplane.

FFFF or other code not listed

1. Place download jumpers on the controller and try to flash the firmware code to the card.

2. Isolate between SCSI subsystem and controller by disconnecting all hard disk drive cables attached to the suspect card, and restart.

Attention: Do not press F5. Doing so changes the server configuration.

If ISPR code is EF10 after disconnecting cables, follow these steps until the error is eliminated:

a. Identify which channel is causing the error by reconnecting cables one at a time and restarting until the error returns.

b. Check termination of identified channel in step 2a.

Note: SCSI channel termination details, if any, appear elsewhere in this publication.

c. Disconnect one drive at a time attached to channel identified in step 2a and restart each time to determine which drive is causing the problem.

d. Replace hard disk drive cable attached to channel identified in step 2a.

e. Replace backplane attached to channel identified in step 2a.

1. If original ISPR code is still present after disconnecting all hard disk drive cables and restarting, perform the following actions until the error is no longer present:

- Reseat the controller

-Replace the controller

Undetermined problems

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

Notes:

1. If you suspect a software mismatch is causing failures (solid or intermittent), be sure to see "Error symptoms" on page 121.
2. Damaged data in CMOS memory can cause undetermined problems.
3. Damaged data in BIOS code can cause undetermined problems. See "Recovering BIOS code" on page 24.

Check the LEDs on all the power supplies (see "Power LED errors" on page 130). If the LEDs indicate 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).

•Any external devices
- Surge-suppressor device (on the server)
•Modem, printer, mouse, or non-IBM devices
•Each adapter
- Hard disk drives
• Memory modules (minimum requirement = 1 GB (2 x 512 MB DIMMs))
•Service processor

Note: Minimum operating requirements are:

• 1 microprocessor

• 2 x 512 MB DIMMs in memory board
  •1 power supply
  •Power backplane
  •I/O board

• Turn on the server. If the problem remains, suspect the following FRUs in the following order:

a. Microprocessor-tray assembly
b. I/O board
c. Memory board
d. Power backplane

Notes:

1. If the problem is solved when you remove an adapter from the server and replacing that adapter does not correct the problem, suspect the I/O board.
2. If you suspect a networking problem and the server passes all the system tests, suspect a network cabling problem external to the server.

Problem-determination tips

Because of 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.

•Machine type and model

•Microprocessor or hard disk upgrades

- Failure symptom

– Does the server fail the diagnostic programs?
- What, when, where, single, or multiple servers?
– Is the failure repeatable?
- Has this configuration ever worked?
- If it has been working, what changes were made before it failed?
– Is this the original reported failure?

• Diagnostics version

- Type and version level

•Hardware configuration

- Print (print screen) configuration currently in use

- BIOS code level

- Operating-system software

- Type and version level

Note: To eliminate confusion, servers are considered identical only if they:

• Are the exact machine type and model
  •Have the same BIOS level
• Have the same adapters and attachments in the same locations
• Have the same address jumpers, terminators, and cabling
• Have the same software versions and levels
• Have the same diagnostics code (version)
• Have the same configuration options set
• Have the same setup for the operating-system control files

Comparing the configuration and software setup between working and non-working servers will often lead to problem resolution.

Power cord FRUs

For your safety, IBM provides a power cord with a grounded attachment plug to use with this IBM product. To avoid electrical shock, always use the power cord and plug with a properly grounded outlet.

IBM power cords used in the United States and Canada are listed by Underwriter's Laboratories (UL) and certified by the Canadian Standards Association (CSA).

For units intended to be operated at 115 volts: Use a UL-listed and CSA-certified cord set consisting of a minimum 18 AWG, Type SVT or SJT, three-conductor cord, a maximum of 15 feet in length and a parallel blade, grounding-type attachment plug rated 15 amperes, 125 volts.

For units intended to be operated at 230 volts (U.S. use): Use a UL-listed and CSA-certified cord set consisting of a minimum 18 AWG, Type SVT or SJT, three-conductor cord, a maximum of 15 feet in length and a tandem blade, grounding-type attachment plug rated 15 amperes, 250 volts.

For units intended to be operated at 230 volts (outside the U.S.): Use a cord set with a grounding-type attachment plug. The cord set should have the appropriate safety approvals for the country in which the equipment will be installed.

IBM power cords for a specific country or region are usually available only in that country or region.

Note: The service procedures are designed to help you isolate problems. They are written with the assumption that you have model-specific training on all computers, or that are familiar with the computers, functions, terminology, and service information provided in this manual.

Safety information

The following section contains the safety information that you need to be familiar with before servicing an IBM computer.

General safety

Follow these rules to ensure general safety:

• Observe good housekeeping in the area of the machines during and after maintenance.

• When lifting any heavy object:

• Ensure you can stand safely without slipping.

• Distribute the weight of the object equally between your feet.
• Use a slow lifting force. Never move suddenly or twist when you attempt to lift.
• Lift by standing or by pushing up with your leg muscles; this action removes the strain from the muscles in your back. Donotattempttoliftanyobjects thatweighmorethan16kg(35lb)orobjectsthatyouthinkaretooheavyfor you.

- Do not perform any action that causes hazards to the customer, or that makes the equipment unsafe.

• Before you start the machine, ensure that other service representatives and the customer's personnel are not in a hazardous position.
• Place removed covers and other parts in a safe place, away from all personnel, while you are servicing the machine.
• Keep your tool case away from walk areas so that other people will not trip over it.
• Do not wear loose clothing that can be trapped in the moving parts of a machine. Ensure that your sleeves are fastened or rolled up above your elbows. If your hair is long, fasten it.
• Insert the ends of your necktie or scarf inside clothing or fasten it with a nonconductive clip, approximately 8 centimeters (3 inches) from the end.
• Do not wear jewelry, chains, metal-frame eyeglasses, or metal fasteners for your clothing.

Remember: Metal objects are good electrical conductors.

• Wear safety glasses when you are: hammering, drilling soldering, cutting wire, attaching springs, using solvents, or working in any other conditions that might be hazardous to your eyes.
  •After service, reinstall all safety shields, guards, labels, and ground wires. Replace any safety device that is worn or defective.
• Reinstall all covers correctly before returning the machine to the customer.

Electrical safety

CAUTION:

Electrical current from power, telephone, and communication cables can be hazardous. To avoid personal injury or equipment damage, disconnect the attached power cords, telecommunication systems, networks, and modems before you open the server covers, unless instructed otherwise in the installation and configuration procedures.

Observe the following rules when working on electrical equipment.

Important: Use only approved tools and test equipment. Some hand tools have handles covered with a soft material that does not insulate you when working with live electrical currents.

Many customers have, near their equipment, rubber floor mats that contain small conductive fibers to decrease electrostatic discharges. Do not use this type of mat to protect yourself from electrical shock.

• Find the room emergency power-off (EPO) switch, disconnecting switch, or electrical outlet. If an electrical accident occurs, you can then operate the switch or unplug the power cord quickly.
• Do not work alone under hazardous conditions or near equipment that has hazardous voltages.
• Disconnect all power before:

– Performing a mechanical inspection
– Working near power supplies
– Removing or installing main units

- Before you start to work on the machine, unplug the power cord. If you cannot unplug it, ask the customer to power-off the wall box that supplies power to the machine and to lock the wall box in the off position.

- If you need to work on a machine that has exposed electrical circuits, observe the following precautions:

- Ensure that another person, familiar with the power-off controls, is near you.

Remember: Another person must be there to switch off the power, if necessary.

- Use only one hand when working with powered-on electrical equipment; keep the other hand in your pocket or behind your back.

Remember: There must be a complete circuit to cause electrical shock. By observing the above rule, you may prevent a current from passing through your body.

• When using testers, set the controls correctly and use the approved probe leads and accessories for that tester.
• Stand on suitable rubber mats (obtained locally, if necessary) to insulate you from grounds such as metal floor strips and machine frames.

Observe the special safety precautions when you work with very high voltages; these instructions are in the safety sections of maintenance information. Use extreme care when measuring high voltages.

• Regularly inspect and maintain your electrical hand tools for safe operational condition.
• Do not use worn or broken tools and testers.
• Never assume that power has been disconnected from a circuit. First, check that it has been powered-off.

•Always look carefully for possible hazards in your work area. Examples of these hazards are moist floors, nongrounded power extension cables, power surges, and missing safety grounds.
- Do not touch live electrical circuits with the reflective surface of a plastic dental mirror. The surface is conductive; such touching can cause personal injury and machine damage.
- Do not service the following parts with the power on when they are removed from their normal operating places in a machine:
– Power supply units
- Pumps
- Blowers and fans
- Motor generators
and similar units. (This practice ensures correct grounding of the units.)

- If an electrical accident occurs:

– Use caution; do not become a victim yourself.
- Switch off power.
– Send another person to get medical aid.

Safety inspection guide

The intent of this inspection guide is to assist you in identifying potentially unsafe conditions on these products. Each machine, as it was designed and built, had required safety items installed to protect users and service personnel from injury. This guide addresses only those items. However, good judgment should be used to identify potential safety hazards due to attachment of non-IBM features or options not covered by this inspection guide.

If any unsafe conditions are present, you must determine how serious the apparent hazard could be and whether you can continue without first correcting the problem.

Consider these conditions and the safety hazards they present:

• Electrical hazards, especially primary power (primary voltage on the frame can cause serious or fatal electrical shock).
• Explosive hazards, such as a damaged CRT face or bulging capacitor
• Mechanical hazards, such as loose or missing hardware

The guide consists of a series of steps presented in a checklist. Begin the checks with the power off, and the power cord disconnected.

Checklist:

1. Check exterior covers for damage (loose, broken, or sharp edges).
2. Turn off the computer. Disconnect the power cord.
3. Check the power cord for:

a. A third-wire ground connector in good condition. Use a meter to measure third-wire ground continuity for 0.1 ohm or less between the external ground pin and frame ground.
b. The power cord should be the appropriate type as specified in the parts listings.
c. Insulation must not be frayed or worn.

1. Remove the cover.

2. Check for any obvious non-IBM alterations. Use good judgment as to the safety of any non-IBM alterations.

3. Check inside the unit for any obvious unsafe conditions, such as metal filings, contamination, water or other liquids, or signs of fire or smoke damage.

4. Check for worn, frayed, or pinched cables.

5. Check that the power-supply cover fasteners (screws or rivets) have not been removed or tampered with.

Handling electrostatic discharge-sensitive devices

Any computer part containing transistors or integrated circuits (ICs) should be considered sensitive to electrostatic discharge (ESD). ESD damage can occur when there is a difference in charge between objects. Protect against ESD damage by equalizing the charge so that the server, the part, the work mat, and the person handling the part are all at the same charge.

Notes:

1. Use product-specific ESD procedures when they exceed the requirements noted here.
2. Make sure that the ESD-protective devices you use have been certified (ISO 9000) as fully effective.

When handling ESD-sensitive parts:

• Keep the parts in protective packages until they are inserted into the product.
• Avoid contact with other people.
• Wear a grounded wrist strap against your skin to eliminate static on your body.
• Prevent the part from touching your clothing. Most clothing is insulative and retains a charge even when you are wearing a wrist strap.
• Use the black side of a grounded work mat to provide a static-free work surface. The mat is especially useful when handling ESD-sensitive devices.
• Select a grounding system, such as those in the following list, to provide protection that meets the specific service requirement.

Note: The use of a grounding system is desirable but not required to protect against ESD damage.

• Attach the ESD ground clip to any frame ground, ground braid, or green-wire ground.
• Use an ESD common ground or reference point when working on a double-insulated or battery-operated system. You can use coax or connector-outside shells on these systems.
• Use the round ground-prong of the ac plug on ac-operated computers.

Grounding requirements

Electrical grounding of the computer is required for operator safety and correct system function. Proper grounding of the electrical outlet can be verified by a certified electrician.
