General checkout

The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system board. These programs are the primary method of testing the major components of the server: the system board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives, and parallel port. You can also use them to test some external devices. See, “Diagnostic tools overview” on page 13.

Also, if you cannot determine whether a problem is caused by the hardware or by the software, you can run the diagnostic programs to confirm that the hardware is working properly.

When you run the diagnostic programs, a single problem might cause several error messages. When this occurs, work to correct the cause of the first error message. After the cause of the first error message is corrected, the other error messages might not occur the next time you run the test.

A failed system might be part of a shared DASD cluster (two or more systems sharing the same external storage device(s). Prior to running diagnostics, verify that the failing system is not part of a shared DASD cluster.

A system might be part of a cluster if:

v The customer identifies the system as part of a cluster. v One or more external storage units are attached to the system and at least one of

the attached storage units is additionally attached to another system or unidentifiable source.

v One or more systems are located near the failing system.

If the failing system is suspected to be part of a shared DASD cluster, all diagnostic tests can be run except diagnostic tests which test the storage unit (DASD residing in the storage unit) or the storage adapter attached to the storage unit.

Notes:

1. For systems that are part of a shared DASD cluster, run one test at a time in looped mode. Do not run all tests in looped mode, as this could enable the DASD diagnostic tests.

2. If multiple error codes are displayed, diagnose the first error code displayed.

3. If the computer hangs with a POST error, go to “Error logs” on page 14.

4. If the computer hangs and no error is displayed, “Diagnostic programs and

error messages” on page 15.

5. Power supply problems, “Power supply LED errors” on page 116.

6. For intermittent problems, check the error log; “Undetermined Problems” on

page 126.

What the IBM xSeries 232 offers

The unique design of the server takes advantage of advancements in symmetric multiprocessing (SMP), data storage, and memory management. The server combines:

v IBM X-Architecture technology

IBM X-Architecture leverages proven innovative IBM technologies to build the most powerful, and reliable Intel processor-based servers in the world.

v Impressive performance using an innovative approach to SMP

The server supports up to two Pentium III microprocessors. The server comes with one microprocessor installed; you can install an additional microprocessor to enhance performance and provide SMP capability.

v Large data-storage and hot-swap capabilities

All models of the server support up to six hot-swap hard disk drives. This hot-swap feature enables you to remove and replace hard disk drives without turning off the server.

The addition of an optional digital linear tape drive (DLT) enables quick backup of large amounts of data.

v IBM integrated system management processor (ISMP)

The integrated system management processor provides environmental monitoring for your server. When environmental conditions exceed thresholds or when system components fail, the ISMP lights the Light Path Diagnostics to indicate the location of the problem. Critical errors, as well as environmental and configuration information, are also included in the error log.

If an optional Remote Supervisor Adapter is installed on the Advanced System Management (ASM) interconnect network, you can view the system health; update the ISMP code; power on, power off, and restart the server; view the error log; view the vital product data; and send alerts over the ASM interconnect network.

v Redundant power capabilities

™

LEDs

General information 5

Page 14

Depending on model, the server comes with either one 385-watt nonredundant power supply, or two 250-watt power-supply units. The two power-supply units provide redundant power for many server configurations. For power loads above 250 watts, a third optional power supply can be installed to provide a full 500 watts of power.

The NON LED on the system board is lit when the power load is 250 watts or greater with two power supplies, or when the power load is 500 watts or greater with three power supplies.

v Large system memory

The memory bus in your server supports up to 4 GB (GB equals approximately 1 000 000 000 bytes) of two-way interleaved system memory. The memory controller provides error correcting code (ECC) support for up to four industry-standard PC133, 3.3 V, 168-pin, 8-byte, registered, synchronousdynamic-random access memory (SDRAM) dual inline memory modules (DIMMs).

v Integrated network environment support

The server comes with an Ethernet controller on the system board. This Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps networks. The server automatically selects between 10BASE-T and 100BASE-TX. The controller provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

v Redundant network interface card

The addition of an optional, redundant network interface card (NIC) provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associated with this primary connection is automatically switched to the redundant NIC. This switching occurs without data loss and without user intervention.

v Optional PCI adapters

The server uses peripheral component interconnect (PCI) bus architecture to provide compatibility with a wide range of existing hardware devices and software applications. The server supports up to five PCI adapters in the expansion slots.

Reliability, availability, and serviceability features

Three of the most important features in server design are reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on your server; that your server is available when you want to use it; and that should a failure occur, you can diagnose and repair the failure with minimal inconvenience.

The following is an abbreviated list of the RAS features that your server supports: v Menu-driven setup, system configuration, RAID configuration, and diagnostic

programs

v Power-on self-test (POST) v ROM-resident diagnostics v Integrated system management processor (ISMP) v Predictive failure alerts v Remote system problem-determination support v Power and temperature monitoring v Microprocessor built-in self-test (BIST) v Internal error signal monitoring v Configuration checking

Diagnostics

This section provides basic troubleshooting information to help you resolve some common problems that might occur with the server.

If you cannot locate and correct the problem using the information in this section, refer to “Symptom-to-FRU index” on page 107 for more information.

Diagnostic tools overview

The following tools are available to help you identify and resolve 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 Light Path Diagnostics

The server has light-emitting diodes (LEDs) to help you identify problems with server components. These LEDs are part of the Light Path Diagnostics feature that is built into the server. By following the path of lights, you can quickly identify the type of system error. See “Identifying problems using status LEDs”

on page 18 for more information.

v Diagnostic programs and error messages

POST

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, the first screen of your operating system or application program appears, and the System POST Complete (OK) light is illuminated on the operator information panel.

If POST detects a problem, more than one beep sounds and an error message appears on your screen. See “Beep Symptoms” on page 107 and “POST error codes” on page 117 for more information.

Notes:

1. If you have a power-on password or administrator password 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.

Page 22

Error logs

The POST error log contains the three most recent error codes and messages that the system generated during POST. The system error log contains all messages issued during POST and system status messages from the integrated system management processor.

Note: It is possible during power-on that some system error log entries may

If you receive a SCSI error message while using the SCSISelect Utility, use the following list to determine the possible cause of the error and what action to take.

Note: If your system does not have a hard disk drive, ignore any message that

indicates that the BIOS code is not installed.

One or more of the following might be causing the problem.

v A failing SCSI device (adapter or drive) v An improper SCSI configuration v Duplicate SCSI IDs in the same SCSI chain v An improperly installed SCSI terminator v A defective SCSI terminator v An improperly installed cable v A defective cable

To solve the problem, verify that: v The external SCSI devices are turned on. External SCSI devices must be turned

on before the server.

v The cables for all external SCSI devices are connected correctly. v The last device in each SCSI chain is terminated properly. v The SCSI devices are configured correctly.

If the above items are correct, run the diagnostic programs to obtain additional information about the failing device. If the error remains or recurs, call for service.

Page 23

Diagnostic programs and error messages

The server diagnostic programs are stored in upgradable read-only memory (ROM) on the system 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.

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 first error message that appears.

The following sections contain the error codes that might appear in the detailed test log and summary log when running the diagnostic programs.

The error code format is as follows:

fff-ttt-iii-date-cc-text message

where: fff is the three-digit function code that indicates the function being tested

when the error occurred. For example, function code 089 is for the microprocessor.

ttt is the three-digit failure code that indicates the exact test failure that was

encountered.

iii is the three-digit device ID. date is the date that the diagnostic test was run and the error recorded. cc is the check value that is used to verify the validity of the information. text message

is the diagnostic message that indicates the reason for the problem.

Text messages

The diagnostic text message format is as follows:

Function Name: Result (test specific string)

where:

Function Name

is the name of the function being tested when the error occurred. This corresponds to the function code (fff) given in the previous list.

Result can be one of the following:

Passed

Failed This result occurs when the diagnostic test discovers an error. User Aborted

This result occurs when the diagnostic test completes without any errors.

This result occurs when you stop the diagnostic test before it is complete.

Diagnostics 15

Page 24

Not Applicable

This result occurs when you specify a diagnostic test for a device that is not present.

Aborted

This result occurs when the test could not proceed because of the system configuration.

Warning

This result occurs when a possible problem is reported during the diagnostic test, such as when a device that is to be tested is not installed.

Test Specific String

This is additional information that you can use to analyze the problem.

Starting 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 the help information and return to where you left off, press Esc.

To start the diagnostic programs:

1. Turn on the server and watch the screen.

2. When the message F2 for Diagnostics appears, press F2.

3. Type the appropriate password; then, press Enter.

4. Select either Extended or Basic from the top of the screen.

5. When the Diagnostic Programs screen appears, 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, call for service.

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 your 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. Also, you can run the USB hub 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 problems do not detect any hardware errors but the problem remains during typical server operations, a software error might be the cause. If you suspect a software problem, refer to the information that comes with the software package.

Viewing the test log

When the tests have 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.

Recovering BIOS code

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

Note: You can obtain a BIOS flash diskette from one of the following sources:

v Use the ServerGuide program to make a BIOS flash diskette. v Download a BIOS flash diskette from the World Wide Web. Go to

http://www.ibm.com/pc/support/, click IBM Server Support, and make the selections for your server.

The flash memory of your server contains 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 flash diskette. The flash utility recovers the system BIOS code from the BIOS recovery files on the diskette.

When you use the Setup and Installation CD, you do not need setup diskettes. You can use the CD to configure any supported IBM server model. The setup program checks your system BIOS, service processors, and other system hardware to determine if system updates are available. The setup program provides a list of tasks that are required to set up your server model. On RAID servers, you can run the ServeRAID Manager program to create logical drives.

Note: Exact features and functions can vary with different versions of the

ServerGuide software.

When you start the Setup and Installation CD, the following happens: v You are prompted for your language, country, and keyboard layout. (This

information is stored and later passed on to the NOS installation program.)

v The ServerGuide program displays choices for running the configuration

programs. For example: – The Express Configuration method runs the required programs for your

server, based on the hardware that is detected.

– The Custom Configuration method displays all programs that are available

for your server, and you decide which programs to run.

– The Replicated Configuration method provides the option of duplicating your

setup selections to other servers that are the same model.

v If you select the Custom Configuration method, the following programs are

optional. If you select the Express Configuration method, some or all of these programs are run, depending on the hardware that is detected.

– The Set Date and Time feature is provided so that you do not have to use the

Configuration/Setup Utility program to access these settings.

– The Clear Hard Disks program is provided so you can delete all partitions on

all hard disk drives. If the server has a ServeRAID adapter installed, you can select to restore the configuration on the ServeRAID adapter to the factory default settings.

– The ServerGuide program checks the server BIOS code and microcode

(firmware) levels for supported options and then checks the CD for a newer level. CD content can be newer than the hardware. The ServerGuide program can perform a flash update of the BIOS code and supported microcode (firmware) options without the use of diskettes.

– The ServeRAID program starts, leading you through the entire configuration

process.

– The Performance Optimizer program easily tunes your server for your

environment.

– The ServerGuide program creates a System Partition on the default drive.

v The ServerGuide program displays a confirmation summary, so that you will

know when you have completed all the required tasks. Then, you are ready to install your NOS.

Notes:

1. Plug and Play adapters are configured automatically. Non-Plug and Play adapters or non-IBM adapters might require switch settings, additional device drivers, and installation after the NOS is installed. See the documentation that comes with the adapter.

2. Diagnostics for your server come in BIOS code or on a separate diagnostics CD.

Configuration 33

Page 42

System Partition

The ServerGuide program creates a 50 MB System Partition on the default drive. The System Partition contains server-specific utility programs such as service processor disk operating system (DOS) utilities, system diagnostics, flash BIOS updates, and other programs.

Note: Programs in the System Partition vary by server model, and not all server

models run utility programs from the System Partition. To determine which ones do, start the Setup and Installation CD and view the online Overview.

After setup is complete, you can access programs in the System Partition by restarting the server and pressing Alt+F1 when the prompt is displayed. The System Partition menu displays the programs that are available on your server model.

Typical NOS installation

You can use the ServerGuide program to shorten your installation time. The ServerGuide program provides the necessary device drivers, based on the hardware that you have and the NOS that you are installing. The following is a brief explanation of a typical ServerGuide NOS installation.

Note: Exact features and functions can vary with different versions of the

ServerGuide software.

v After you have completed the setup process, the operating-system installation

program starts. (You will need your copy of the NOS CD to complete the installation.)

v The ServerGuide program stores information about the server model, service

processor, hard disk controllers, and network adapters. It then checks the CD for newer device drivers. This information is stored and then passed to the NOS installation program.

v With some NOS installations, you can create a NOS Replication Diskette for

setting up additional servers. The diskette will contain the Internet protocol (IP) address, server name, and other selections.

v The ServerGuide program presents NOS partition options that are based on your

NOS selection and the installed hard disk drives.

v If you are installing the NOS from diskette, the ServerGuide program displays

the required diskettes that you must create and the optional diskettes that you might want to create. The diskettes that you can create are the device-driver diskettes for the installed adapters or controllers.

The ServerGuide program prompts you to insert your NOS CD and restart the server. At this point, the installation program for the NOS takes control to complete the installation.

Setting up or updating multiple servers

You can use the ServerGuide program to create diskettes that help you set up or update multiple servers. You can modify information on the diskettes as you use them to set up or update other servers.

Note: Availability and function can vary by server model and by the hardware

that is installed.

Adapter considerations

Before you install adapters, review the following: v Locate the documentation that comes with the adapter and follow those

instructions in addition to the instructions given in this chapter. If you need to change the switch or jumper settings on your adapter, follow the instructions that come with the adapter.

v You can install full-length adapters in all expansion slots. v You can install a 32-bit adapter or device in any of the PCI slots. v Your server supports 5.0 V signalling or universal PCI adapters in slots 1, 2, and

3; it supports 3.3 V signalling or universal PCI adapters in slots 4 and 5.

Note: Some full-length adapters with attached daughterboards might interfere

with SCSI channel B if installed in slot 1. Install this type of adapter in slot 2, 3, 4, or 5.

v You might require additional power supplies if you add adapters that have

electrical current requirements that exceed the installed power-supply capabilities.

v Your server uses a rotational interrupt technique to configure PCI adapters.

Therefore, you can install a variety of PCI adapters that currently do not support sharing of PCI interrupts.

v The optional IBM Remote Supervisor Adapter must be installed in PCI slot 1

only. Use the ribbon cable that comes with the adapter to connect the adapter to the system-management connector (J54) on the system board. The external power adapter that comes with the adapter is not required with this server.

v PCI slot 1 is on PCI bus A, PCI slots 2 and 3 are on PCI bus B, and PCI slots 4

and 5 are on PCI bus C.

Note: PCI bus A is often referred to as bus 0; PCI bus B is often referred to as

bus 1; and PCI bus C is often referred to as bus 2.

Installing options 55

Page 64

v The system scans PCI slot 1, the system board Ethernet, PCI slots 2 through 5,

and then the system board SCSI channels A and B, if you have not changed the boot precedence from the default.

or restrictions.

4. Remove the expansion-slot cover: a. Press the arrow on the adapter-retention bracket release tab and remove

the bracket.

b. Slide the expansion-slot cover out of the server. Store it in a safe place for

future use.

Attention: Expansion-slot covers must be installed in all vacant slots. This maintains the electronic emissions characteristics of the system and ensures proper cooling of system components.

5. Refer to the documentation that comes with the adapter for any cabling instructions. It might be easier for you to route any cables before you install the adapter.

6. Remove the adapter from the static-protective package.

56 Hardware Maintenance Manual: xSeries 232, Type 8668

Page 65

Attention: Avoid touching the components and gold-edge connectors on the adapter.

7. Place the adapter, component-side up, on a flat, static-protective surface.

8. Set any jumpers or switches as described by the adapter manufacturer.

9. Install the adapter: a. If you are installing a full-length adapter, remove the adapter support

bracket retaining clip.

b. Carefully grasp the adapter by its top edge or upper corners, and align it

with the expansion slot on the system board.

c. Press the adapter firmly into the expansion slot.

Attention: When you install an adapter in the server, be sure that it is completely and correctly seated in the system board connector before you apply power. Incomplete insertion might cause damage to the system board or the adapter.

10. Replace the retaining clip on the adapter support bracket, if you removed it.

11. Align the bottom tabs of the adapter-retention bracket with the holes at the

top of the expansion slots, and press the adapter-retention bracket into the holes until it clicks into the locked position.

12. Connect any needed cables to the adapter.

Attention: Route cables so that the flow of air from the fans is not blocked. In addition, route any cables plugged into the PCI adapter under adjacent adapters so they are not pinched between the top of the adapter and the top cover.

The following illustration shows the rerouting of the SCSI cable if you install a ServeRAID adapter (remove the cable from SCSI connector A (J24) on the system board and connect it to the ServeRAID adapter).

Hot-swap drives

Your server contains hardware that enables you to continue to operate your system while a hard disk drive is removed or installed. These drives are known as hot-swap drives.

Each hot-swap drive that you plan to install must have a hot-swap-drive tray attached. Hot-swap-drive trays come with the hot-swap drives.

v Your server supports six slim (1-inch) line, SCSI LVD, 3.5-inch hot-swap hard

disk drives in the hot-swap bays.

v The hot-swap bays are connected to a SCSI backplane. This backplane is the

printed circuit board behind the bay.

v The backplane controls the SCSI IDs for the hot-swap drives.

Non-hot-swap drives

Diskette drives, tape drives, and CD-ROM drives are non-hot-swap drives. To remove or install a non-hot-swap drive, you must turn off the server first. Non-hot-swap drives are installed in bays A, B, C, and D only.

v Your server comes with a preinstalled 3.5-inch, 1.44 MB diskette drive in bay D

and a preinstalled IDE CD-ROM drive in bay C.

v The xSeries 232 server supports only one diskette drive. v The diskette drive uses 1 MB and 2 MB diskettes. For optimum use, format

1 MB diskettes to 720 KB, and format 2 MB diskettes to 1.44 MB.

v Bays A and B come without devices installed. These bays are for 5.25-inch,

half-high, removable-media drives, such as tape backup drives. You can combine bays A and B into a single full-high bay.

v If you are installing a SCSI device with a 50-pin connector in one of the empty

non-hot-swap bays (bays A and B), you need a 68-pin to 50-pin converter. To order the converter, contact your IBM reseller or IBM marketing representative.

Note: The server electromagnetic interference (EMI) integrity and cooling are both

protected by having bays A and B covered or occupied. When you install a drive, save the filler panel from the bay, in case you later remove the drive and do not replace it with another.

Preinstallation steps (all bays)

Before you install drives in the server, verify that you have all the cables and any other equipment specified in the documentation that comes with the internal drive. You might also need to perform certain preinstallation activities. Some of the steps are required only during the initial installation of an option.

1. Review the information in “Before you begin” on page 47, “Safety information” on page 133, and the documentation that comes with the drive.

2. Choose the bay in which you want to install the drive.

3. Check the instructions that come with the drive to see if you need to set any

switches or jumpers on the drive.

4. To install the drive, go to “Hot-swap drive installation” or to “Non-hot-swap

drives” on page 62, as appropriate.

To install a drive in a hot-swap drive bay:

Attention:

v To maintain proper system cooling, do not operate the server for more than 2

minutes without either a drive or a filler panel installed in each bay.

v When you handle static-sensitive devices, take precautions to avoid damage

from static electricity. For details on handling these devices, review “Handling electrostatic discharge-sensitive devices” on page 136.

1. If your server is a tower model, unlock and open the server door.

Attention: To maintain proper system cooling, do not operate the server for more than 2 minutes without either a drive or a filler panel installed in each bay.

2. Remove the filler panel from one of the empty hot-swap bays by inserting your

finger into the depression at the left side of the filler panel and pulling it away from the server.

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

a. Ensure the tray handle is open (that is, perpendicular to the drive). b. Align the rails on the drive assembly with the guide rails in the drive bay. c. Gently push the drive assembly into the bay until the drive connects to the

backplane.

d. Push the tray handle toward the closed position until it locks the drive in

place.

60 Hardware Maintenance Manual: xSeries 232, Type 8668

Page 69

4. Check the hard disk drive status indicators to verify that the hard disk drives are operating properly (see “Internal drive bays” on page 58 for the location of the status indicators).

v If the amber light is on continuously, the drive has failed. v If you have a RAID adapter installed:

– When the amber light flashes slowly (one flash per second), the drive is

being rebuilt.

– When the amber light flashes rapidly (three flashes per second), the

controller is identifying the drive.

5. If your server is a tower model, close and lock the server door.

Note: If the server has a RAID adapter installed, refer to the information provided

with the RAID adapter for information about adding a drive.

Hot-swap drive replacement

You do not have to turn off the server to remove or install the hot-swap drives.

Attention:

1. Before you remove a hot-swap hard disk drive that is not defective, back up all important data.

2. To avoid damage to a hard disk drive, do not remove the drive from the hot-swap bay until it has had time to spin down (approximately 30 seconds). Handle the drive carefully.

3. Before you replace a hot-swap drive, make sure it is defective. If you partially or completely remove a good drive instead of a defective one, your server might lose data.

This situation is especially relevant if your server has a RAID adapter installed and you assigned RAID level 1 or 5 to the logical drives in your disk array. The RAID adapter can rebuild the data that you need, provided that certain conditions are met. Refer to the information provided with the RAID adapter for further details.

Refer to the following illustration of the tower model while you perform the steps in this procedure.

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

7. If you have other options to install or remove, do so now; otherwise, go to “Completing the installation” on page 82.

Memory modules

Adding memory to your server is an easy way to make programs run faster. You can increase the amount of memory in your server by installing options called memory-module kits. Each kit contains one industry-standard, dual inline memory module (DIMM). Your server supports a two-way interleaved memory configuration. You must install matched pairs of memory kits. The set in slots 1 and 4 do not need to be the same size as the set in slots 2 and 3.

Notes:

1. Your server comes with two DIMMs installed in DIMM connectors 1 and 4. Install additional DIMMs as instructed in the documentation that comes with your option.

2. Your xSeries 232 server supports 128 MB, 256 MB, 512 MB, and 1 GB DIMMs. You must install the DIMMs in pairs of the same size. Place pair 1 in slots 1 and 4 and pair 2 in slots 2 and 3. Refer to the ServerProven Wide Web at http://www.ibm.com/pc/compat/ for information about memory modules for use with your server.

3. Installing or removing DIMMs changes the configuration information in the server. Therefore, after installing or removing a DIMM, you must save the new configuration information in the Configuration/Setup Utility program. When you restart the server, the system displays a message indicating that the memory configuration has changed. Start the Configuration/Setup Utility program and select Save Settings.

Microprocessor kit installation

The server comes with one microprocessor installed on the system board. If you install an additional microprocessor, the server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between the microprocessors. This enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Notes:

1. Before you install a new microprocessor, review the documentation that comes with the microprocessor, so that you can determine whether you need to update the server basic input/output system (BIOS) code. The latest level of BIOS code for the server is available through the World Wide Web.

2. Obtain an SMP-capable operating system (optional). For a list of supported operating systems, see http://www.ibm.com/pc/compat/ on the World Wide Web.

3. The server comes with one microprocessor installed in the microprocessor connector (U68) that is closest to the power supply. This is the startup (boot) microprocessor. A microprocessor installed in connector U69 is microprocessor

2. If more than one microprocessor is installed, the microprocessor installed in microprocessor connector U69 is the startup processor, and the microprocessor installed in U68 is the application microprocessor.

Attention: To avoid damage and ensure proper server operation when you install a new or additional microprocessor, use microprocessors that have the same cache size and type, and the same clock speed. See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of microprocessors for use with the server.

7. If you have other options to install or remove, do so now.

Hot-swap power supply removal

If you have a hot-swap power-supply backplane and have installed power supplies, you normally have power redundancy and hot-swappability. However, if the load on your server requires the capacity of all installed power supplies, you do not have redundancy or hot-swappability and must turn off the server before removing any of your power supplies.

Important: If you do not have power redundancy, and you remove a power supply while the system is running, your system will immediately power off.

To remove a power supply:

1. Check the Information light operation information panel on the front of the server. If on, check the NON (nonredundant) LED (CR24) on the diagnostic panel on the system board.

74 Hardware Maintenance Manual: xSeries 232, Type 8668

7. Verify that the ac power light and dc power light are lit, indicating that the power supply is operating correctly.

Power supply conversion from non-redundant to redundant

You can build a fault-tolerant power system by upgrading to a power-sharing backplane. The power-sharing backplane replaces the standard power backplane and allows you to use up to three 250-watt hot-swap power supplies for power sharing. You can maintain a redundant configuration with two power supplies, which allows the system to continue operation even if one power supply fails. Implementing a third power supply ensures redundancy even if one power supply fails. The backplane will alert you when redundancy is lost with the two or three power supplies configuration.

Removing the existing power supply: Use the following steps to remove the existing 385-watt power supply from the server:

1. Turn off the server and peripheral devices and disconnect all external cables and power cords; then remove the cover (see “Removing the cover, door, and bezel” on page 48 for details).

communications.

Refer to the Remote Supervisor Adapter option documentation for detailed information about the ASM interconnect network.

Universal Serial Bus ports

Your server has two Universal Serial Bus (USB) ports, which are configured automatically. USB is an emerging serial interface standard for telephony and multimedia devices. It uses Plug and Play technology to determine the type of device attached to the connector.

Notes:

1. If you attach a standard (non-USB) keyboard to the keyboard connector, the USB ports and devices will be disabled during the power-on self-test (POST).

2. If you install a USB keyboard that has a mouse port, the USB keyboard emulates a mouse and you will not be able to disable the mouse settings in the Configuration/Setup Utility program.

USB cables and hubs: You need a 4-pin cable to connect devices to USB 1 or USB

2. If you plan to attach more than two USB devices, you must use a hub to connect

the devices. The hub provides multiple connectors for attaching additional external USB devices.

USB technology provides up to 12 Mbps speed with a maximum of 127 external devices and a maximum signal distance of 5 meters (16 ft) per segment.

Ethernet ports

The server comes with an integrated Ethernet controller. This controller provides an interface for connecting to 10-Mbps or 100-Mbps networks and provides full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet local area network (LAN).

To access the Ethernet ports, connect a Category 3, 4 or 5 unshielded twisted-pair (UTP) cable to the RJ-45 connector on the rear of your server.

Note: The 100BASE-TX Fast Ethernet standard requires that the cabling in the

network be Category 5 or higher.

Configuring the Ethernet controllers: When you connect your server to the network, the Ethernet controllers automatically detect the data-transfer rate (10 Mbps or 100 Mbps) on the network and then set the controllers to operate at the appropriate rate. In addition, if the Ethernet ports that your server is connected to support auto-negotiation, the Ethernet controllers will set the appropriate duplex state. That is, the Ethernet controllers will adjust to the network data rate, whether the data rate is standard Ethernet (10BASE-T), Fast Ethernet (100BASE-TX), half duplex (HDX), or full duplex (FDX). The controllers support half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

The Ethernet controllers are PCI Plug and Play devices. You do not need to set any jumpers or configure the controllers for your operating system before you use the Ethernet controllers. However, you must install a device driver to enable your operating system to address the Ethernet controllers. The device drivers are provided on the ServerGuide CDs.

Failover for redundant Ethernet: The IBM 10/100 Ethernet Adapter or the IBM 10/100 EtherJet

™

PCI family of adapters are optional redundant network interface cards (NICs) that you can install in your server. If you install this NIC and connect it to the same logical segment as the primary Ethernet controller, you can configure the server to support a failover function. You can configure either one of the integrated Ethernet controllers or the NIC as the primary Ethernet controller. In failover mode, if the primary Ethernet controller detects a link failure, all Ethernet traffic associated with it is switched to the redundant (secondary) controller. This

88 Hardware Maintenance Manual: xSeries 232, Type 8668

Page 97

switching occurs without any user intervention. When the primary link is restored to an operational state, the Ethernet traffic switches back to the primary Ethernet controller.

High-performance Ethernet Modes: Your Ethernet controllers support optional modes, such as teaming, priority packets, and virtual LANs, which provide higher performance and throughput for your server.

Teaming mode: Your Ethernet controllers provide options, called teaming options. These options increase throughput and fault tolerance when running with Windows NT 4.0 or NetWare 4.1x or later.

v Adapter fault tolerance (AFT) provides automatic redundancy for your adapter.

If the primary adapter fails, the secondary adapter takes over. Adapter fault tolerance supports from two to four adapters per team.

v Adaptive load balancing (ALB) enables you to balance the transmission data

flow among two to four adapters. ALB also includes the AFT option. You can use ALB with any 100BASE-TX switch.

v Cisco Fast Ether Channel (FEC) creates a team of two to four adapters to

increase transmission and reception throughput. FEC also includes the AFT option. You can use FEC only with a switch that has FEC capability.

Teaming requires you to install both integrated Ethernet controllers. For additional information about the teaming modes, refer to the documentation that comes with these additional adapters.

Priority Packet mode: Priority Packet is a traffic-prioritization utility that enables you to set up filters to process high-priority traffic before normal traffic. You can send information from critical nodes or applications with an indicated priority. Because you set this priority at the host or entry point of the network, the network devices can base forwarding decisions on priority information defined in the packet.

Priority Packet information is available on the IBM Networking Web site at http://www.ibm.com/networking/support/.

Priority Packet prioritizes traffic based on priority filters. These are parameters you assign to outgoing (transmit) packets. Using the priority-filter wizard, you can set up predefined or custom priority filters based on a node (MAC) address, Ethernet type, or by various properties of the protocol and port. Priority Packet provides two different methods for prioritizing traffic: IEEE 802.1p tagging and High Priority Queue.

IEEE 802.1p is an IEEE standard for tagging, or adding additional bytes of information to packets with different priority levels. Packets are tagged with 4 additional bytes, which increase the packet size and indicate a priority level. When you send these packets out on the network, the higher priority packets are transferred first. Priority packet tagging (also known as Traffic Class Expediting) enables the adapter to work with other elements of the network (such as switches and routers) to deliver priority packets first. You can assign specific priority levels from 0 (low) to 7 (high).

You can assign values to packets based on their priorities when you use the IEEE

802.1p standard for packet tagging. This method requires a network infrastructure that supports packet tagging. The routing devices receiving and transferring these packets on your network must support 802.1p for tagging to be effective.

Installing options 89

Page 98

After you set up the priority filter in Priority Packet, you must start IBMSet and select 802.1p/802.1Q Tagging on the Advanced page.

Note: IEEE 802.1p tagging increases the size of the packets it tags. Some hubs and

switches will not recognize the larger packets and will drop them. Check your hub or switch documentation to see if they support 802.1p. (You can configure the switch to strip the tags from the packets and send it on to the next destination as normal traffic.) If these devices do not support 802.1p or if you are not sure, use High Priority Queue (HPQ) to prioritize network traffic.

The requirements for effectively using IEEE 802.1p tagging are: v The other devices receiving and routing 802.1p tagged packets must support

802.1p.

v The adapters on these devices must support 802.1p. The Ethernet controller in

your server, all IBM Netfinity 10/100 Ethernet Security Adapters, and IBM 10/100 Ethernet Server Adapters support 802.1p.

v The adapter cannot be assigned to an adapter team. v If you are setting up VLANs and packet tagging on the same adapter,

802.1p/802.1Q Tagging must be enabled on the IBMSet Advanced page.

If your network infrastructure devices do not support IEEE 802.1p or you are not sure, you can still define filters and send packets as high priority. While High Priority Queue (HPQ) does not provide the precise priority levels of 802.1p tagging, it does assign traffic as either high or low priority and sends high-priority packets first. Therefore, if there are multiple applications on a system sending packets, the packets from the application with a filter are sent out first. HPQ does not change network routing, nor does it add any information to the packets.

To assign HPQ, you can specify it using Priority Packet when you create or assign a filter.

To effectively use HPQ, the adapter cannot be assigned to an adapter team.

Virtual LAN mode: A virtual LAN (VLAN) is a logical grouping of network devices put together as a LAN, regardless of their physical grouping or collision domains. Using VLANs increases network performance and improves network security.

VLANs offer you the ability to group users and devices together into logical workgroups. This can simplify network administration when connecting clients to servers that are geographically dispersed across a building, campus, or enterprise network.

Normally, VLANs are configured at the switch and any computer can be a member of one VLAN per installed network adapter. Your Ethernet controller supersedes this by communicating directly with the switch, enabling multiple VLANs on a single network adapter (up to 64 VLANs).

To set up VLAN membership, your Ethernet controller must be attached to a switch that has VLAN capability. You also need to use Windows NT 4.0 or later, or Novell NetWare 4.1x or later.

Notes:

1. Windows NT versions prior to 4.0 do not support VLANs.

90 Hardware Maintenance Manual: xSeries 232, Type 8668

Page 99

2. VLANs require Windows NT 4.0 with Service Pack 3.0 and the NDIS driver from Microsoft.

3. In Windows NT, VLANs cannot be implemented on controllers that have been configured for teaming options. NetWare can support teaming options and VLANs on the same adapters.

To join a VLAN from Windows NT 4.0:

1. Create a VLAN on the switch. Use the parameters you assign there to join the VLAN from the server. Refer to your switch documentation for more information.

2. Double-click the Network icon in the Control Panel window.

3. On the Adapters page, select the adapter you want to be on the VLAN and

click Properties.

4. In IBMSet, click Join VLAN. Note that VLANs cannot be assigned to adapters that are already defined to have an adapter teaming option.

5. Type the VLAN ID and VLAN name. The VLAN ID must match the VLAN ID of the switch. The ID range is from 1 to 1000. The VLAN name is for information only and does not need to match the name on the switch.

6. Click Join VLAN. Repeat steps 3 through 5 for each VLAN you want the server to join. The VLANs you add are listed on the Adapters page.

7. Click Close and restart the computer.
