Important Information

The power line and power control behavior of the Netfinity 3500 M10 is different from some earlier server models. Please observe the following:

 When the power cord is first plugged in, the

server may appear to power on for a few seconds, then power off. This is a normal sequence to enable the server to self initialize.

 The power switch will normally operate with a

single touch. However, in some circumstances the server may not immediately power off. In this case, hold the power switch down for approximately 5 seconds. The server will then turn off.

The cover should always be on when operating your server. Proper cooling is required for the reliable performance of internal components.

Attention

The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving, or formatting. Data or programs can be overwritten if you select an incorrect drive.

Diagnostic error messages appear when a test program finds a problem with a hardware option. For the test programs to properly determine if a test

Aborted

, the test programs check the error-return code at

test completion. General error messages appear if a problem or conflict is

found by an application program, the operating system, or both. For an explanation of these messages, refer to the information supplied with that software package.

Notes

1. Before replacing any FRUs, ensure the latest level of BIOS is installed on the system. A down-level BIOS might cause false errors and unnecessary replacement of the system board.

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

3. If the computer hangs with a POST error, go to “Symptom-to-FRU index” on page 142.

4. If the computer hangs and no error is displayed, go to “Undetermined problem” on page 189.

5. If an installed device is not recognized by the diagnostics program, that device might be defective.

Passed, Failed

, or

The power-on default is quick bring-up. To enable Enhanced bring-up, select the Start Options in the Configuration/Setup Utility program (see “Start Options” on page 28) then, enable Power On Status.

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:

 The customer identifies the system as part of a

cluster.

 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.

 One or more systems are located near the failing

system.

Netfinity 8655 - Type 8655

If the failing system is suspect to be part of a shared DASD cluster, all diagnostic tests can be run except diagnostic tests which tests 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 the “Symptom-to-FRU index” on page 142.

4. If the computer hangs and no error is displayed, go to “Undetermined problem” on page 189.

5. Power Supply problems, see “Power supply” on page 59.

Netfinity 8655 - Type 8655 7

Diagnostics

Computer problems can be caused by hardware, software, or user error (for example, pressing the wrong key). The following tools are available to help identify and resolve hardware-related problems.

Power-on self test (POST)

Each time you turn on your computer, a series of tests that check the basic operation of the computer are performed. This series of tests is called

Note

If your computer does not start when you press the power switch, do the following:

 Make sure all cables are securely connected to

the correct locations.

 Make sure the computer cover is installed

properly (pushed all the way on).

If this does not correct the problem, go to “General Checkout” on page 5.

POST does the following:

 Checks basic system-board operations  Checks the memory operation  Compares the current system configuration with that

established by the Configuration/Setup Utility program

 Starts the video operation  Verifies that the diskette drives are working  Verifies that the hard disk drive and the CD-ROM

drive are working

If Power On Self Test is set to [ showing the amount of memory being tested appear in the top-left corner of the screen until the total amount of memory in the system is reached. Quick mode is the default mode of operation. Options for running a quick POST or accessing the Configuration/Setup Utility program appear in the lower-left corner of the screen.

Note

The amount of available memory shown might be somewhat less than expected because of basic input/output system (BIOS) shadowing in random access memory (RAM).

If Power On Status is problem, you will hear multiple beeps or no beep. In most cases, an error code appears in the top left corner of the screen, and in some cases a description of the error is displayed beside the code. (Note that the screen will sometimes display multiple error codes and descriptions.) For more information about what caused an error message to appear and what action to take, refer to “Solving POST Error Message Problems” on page 53 and “Symptom-to-FRU index” on page 142.

If you hear no beep at all during POST, go to “General Checkout” on page 5.

and POST detects a

Types of Error Messages

Error messages that appear on the screen might be text, numeric, or both. There are several types of error messages:

POST error messages: These messages appear

when POST finds problems with the hardware during startup or when a change in the hardware configuration is found. POST error messages are 3-, 4-, 5-, 8-, or 12-character alphanumeric messages and include brief explanations (except I999XXXX errors).

For more information about what caused an error message to appear and what action to take, refer to “Solving POST Error Message Problems” on page 53 and “Symptom-to-FRU index” on page 142.

Errors Specific to the Integrated Ethernet Subsystem: If a failure Ethernet error condition

occurs after the Ethernet controller is initialized, an error message appears on the screen. The two most common error types are

DHCP-related error messages

RPL-ROM-ERR: 15 The Integrated Ethernet failed the loopback test E62: Cannot initialize controller.

If you experience any error related to the integrated Ethernet subsystem, record the error message, and tell your network administrator about the problem.

SCSI error messages: These messages appear if

a problem or conflict is detected by the Adaptec SCSI subsystem. Refer to the SCSI documentation that comes with your computer for information about these messages.

Netfinity 8655 - Type 8655

Software-generated error messages: These

messages appear if a problem or conflict is detected by the application program, the operating system, or both. Error messages for operating-system and other software problems are generally text messages, but they also can be numeric messages. For information about these software error messages, refer to the information that comes with the operating system or application program, or both.

Diagnostic error codes and messages:

These codes and messages appear if a hardware problem is detected by one of the IBM Enhanced Diagnostics test programs. Along with error codes, the messages present text information that can be used to identify a failing part.

Error Messages Specific to the Integrated Ethernet Subsystem

Note

The error messages shown in this section are available only with the integrated Ethernet subsystem. These error messages are not available when RPL (remote program load) or DHCP (dynamic host configuration protocol) is used through optional network adapters.

If a failure condition occurs after the Ethernet controller is initialized, an error message appears on the screen. The error messages that can occur are shown below. If you experience any error related to the integrated Ethernet subsystem, record the error message, and tell your network administrator about the problem.

RPL-Related Error Messages: These error

messages are specific to the integrated Ethernet controller and the RPL environment of your computer.

The two most common error messages are shown below.

RPL-ROM-ERR: 15 The integrated Ethernet failed the loopback test. RPL-ROM-ERR: 17 Media test failed; check the cable.

Error 105 indicates that a power-on diagnostic test performed by the Ethernet module did not execute correctly. If this error message appears, you must have the computer serviced. Error 107 indicates that the cable from the LAN is not securely connected to the Ethernet port on your computer. Check the cable to ensure that it is properly connected.

Other error messages that might occur are shown in the following table.

RPL-ROM-ERR: 100 The integrated Ethernet cannot be found.

RPL-ROM-ERR: 101 The integrated Ethernet was unable to initialize.

RPL-ROM-ERR: 102 The integrated Ethernet could not be reset.

RPL-ROM-ERR: 103 There are multiple Ethernets in the system.

RPL-ROM-ERR: 104 The integrated Ethernet EEPROM is faulty or not present.

RPL-ROM-ERR: 106 The integrated Ethernet is configured for Plug and Play in non-Plug and Play system.

Beep Codes

Audible beep codes are designed as a way to alert the user of errors detected during POST when error codes cannot be displayed. Each beep code is represented by a number sequence. For example, a “2-3-2” error symptom (a burst of two beeps, three beeps, then two beeps) indicates a memory module problem. See “Beep symptoms” on page 143 for a description of each beep code.

and, in some cases, hardware features, including ROM shadowing, PCI control, and Plug and Play Control. These settings must be configured correctly; otherwise, your server might malfunction.

Cache Control, Cache State, L2 Cache Size. The Cache

Control menu shows how much cache memory is installed and lets you enable or disable its use. Cache memory is special buffer storage that holds frequently used instructions and data, and works faster than main memory. With cache memory enabled, most of your programs will run faster. If you run programs that require slower speeds, you can disable cache memory to slow down your server.

ROM Shadowing The ROM Shadowing menu shows

which system devices are using read-only memory (ROM) shadowing. With ROM shadowing, your server stores data from the specified device in random access memory

(RAM). Because your server can access data in RAM faster than it can access data from ROM, programs run faster when ROM shadowing is enabled. If you install an adapter that has its own ROM, you can enable the ROM shadowing option for that adapter to speed up its performance.

Note

The ROM Shadowing option might not work on adapters that use memory-mapped I/O, such as network adapters.

PCI Control, PCI Adapter Reset, PCI Parity, Network

Adapters, Mass Storage Adapters, Display Adapters, Multimedia Devices, Communication Adapters, Serial Adapters. Use PCI control to enable or

disable PCI parity and bus mastering for the PCI adapters installed in your server. PCI Adapter Reset can be enabled or disabled. PCI parity allows parity checking of data across the PCI bus. Some adapters do not generate parity and will require the PCI Parity option be set to Disabled. Bus mastering lets installed bus master PCI adapters process information without using the microprocessor.

Note

The default bus master setting for all devices is enable. Do not change this setting. Some devices or adapters might not work properly if the bus master function is enabled when the system is restarted.

The PCI Control Menu is Setup allows you to disable bus mastering for any device that is displayed on the menu. Devices not displayed on the menu cannot be disabled.

Note

If PCI adapters do not operate properly, you might need to disable the PCI Bus Master option.

Plug and Play Control, Set Device Node, Address

Decode, Plug and Play Operating System.

Use Plug and Play Control to change certain settings for Plug and Play devices. Set Device Node: When this option is disabled, programs will not be able to make changes to the power-on configuration. Address

Decode: Most Plug and Play adapters use 16-bit address decoding. If you are experiencing problems with a Plug and Play adapter, changing the address decode setting to 10-bit might fix the problem. Plug and Play Operating System: Select Yes for this option if you are experiencing POST errors numbered 185x and your startup operating system is Plug and Play compliant. See your operating system documentation to determine if your operating system supports this function.

Processor Speed Control, Processor ID, Processor

Updating, Processor Serial Number Access. If you install a microprocessor, use

this option to set the microprocessor speed. Ensure that you set the correct speed. If you select a speed that is faster than the microprocessor supports, unpredictable results might occur. The Processor ID is displayed. Enabling or disabling Processor Updating determines whether the BIOS will apply microprocessor updates when the server starts. Enabling or disabling Processsor Serial Number Access determines whether the microprocessor serial number can be accessed (queried) by websites on your intranet or the internet. For example, you would enable this function if your company uses it to track assets.

Netfinity 8655 - Type 8655 33

ISA Legacy Resources: If you select ISA Legacy

Resources from the Configuration/Setup Utility main menu, you can configure non-Plug and Play adapters, which are not automatically detected by your server. You must identify the following ISA Legacy resources as dedicated to your new adapter so the BIOS does not attempt to assign them to Plug and Play adapters:

 Memory Resources

 I/O Port Resources  DMA Resources  Interrupt Resources

Each of the options on the ISA Legacy Resources menu opens another menu.

Memory Resources Use Memory Resources to allocate

system memory regions for an adapter. The menu lists the hexadecimal addresses of the available memory regions. You allocate memory to an adapter by selecting the ISA Resource setting for an available hexadecimal address. Be sure to read the documentation that comes with your adapter. You might need to make changes to the adapter to accommodate the selections you make for Memory Resources. For example, you might have to move jumpers or switches on the adapter, or make changes to the software that comes with the adapter.

I/O Port Resources Use I/O Port Resources to allocate

input/output ports for an adapter. The menu lists the hexadecimal addresses of the available I/O ports. You allocate I/O ports to an adapter by selecting the ISA Resource setting for an available hexadecimal address. Be sure to read the documentation that comes with your adapter. You might need to make changes to the adapter to accommodate the selections you make for I/O Port Resources. For example, you might have to move jumpers or switches on the adapter, or make changes to the software that comes with the adapter.

DMA Resources Use DMA Resources to allocate direct

memory access (DMA) channels for an adapter. The menu lists the channel assignments for DMA, which allows I/O devices to transfer data to and from memory. You allocate DMA channels to an adapter by selecting the ISA Resource setting for an available channel. Be sure to read the documentation that comes with your adapter. You might need to make changes to the adapter to accommodate the selections you

Netfinity 8655 - Type 8655

Important information

This information applies only to those who are running Windows NT Server and have a mouse connected to the mouse port; a serial mouse is not affected by the password prompt Off mode.

The password prompt Off mode prevents the server from detecting that a mouse is attached. Because the mouse device driver will not be loaded automatically through the CONFIG.SYS or AUTOEXEC.BAT files in this mode, an error message that the mouse port is disabled will appear and the server will halt. To enable the operating system to load without displaying the error message, do the following:

When the server is started and the mouse port disabled error message appears, type either your power-on or administrator password to enable the keyboard. Then use the keyboard to put a check mark in the Do not display this message in the future check box.

Once the operating system starts in password prompt Off mode, the keyboard will remain locked. If you have a mouse connected to the mouse port, it also will remain locked.

Although you are not prompted to type a password in this mode, you can type either your power-on or administrator password anytime after POST has completed, even after the operating system has loaded. If you type a password, the keyboard will unlock, but the mouse connected to the mouse port will remain disabled.

If a power failure occurs, the server will automatically restart and resume operating in this mode when power is restored, without operator intervention.

Note

The password prompt Off mode does not support any locally or remotely scheduled shutdowns or restarts. Therefore, do not use a power-on wakeup or lockout function.

Dual In the password prompt Dual mode, the

startup behavior of the server depends on whether the computer is started from the computer power switch or by an unattended method, such as a modem or timer.

If you start the server by using the power switch, the computer operates the same as it does in password prompt On mode. Refer to page 37 for further information.

If the server is started by an unattended method, such as remotely over a LAN, the server operates the same as it does in password prompt Off mode. Refer to page 37 for further information.

Enhanced security: By default, your administrator

password is stored in CMOS memory. CMOS memory is battery-powered memory that stores your configuration, setup, and security settings. The information stored in CMOS remains there for the life of the battery, as long as the battery is not removed.

Your server has an enhanced security feature that provides extra protection for your administrator password, as well as your startup (boot) sequence settings. With enhanced security, your administrator password and startup sequence are stored in a highly-protected, nonvolatile, security EEPROM module that is separate from CMOS memory and the EEPROM module that stores system programs. When your administrator password and startup sequence are locked in the security EEPROM, they remain intact even if the battery in your server expires or is removed by someone.

Netfinity 8655 - Type 8655

Enhanced security can be enabled or disabled only when you update system programs. The procedure for enabling enhanced security is explained under “Enabling and disabling enhanced security” on page 45.

If enhanced security is enabled and you have not set an administrator password, your server will operate as if enhanced security were disabled. If enhanced security is enabled and you have set an administrator password, your server will operate as follows:

 The contents of the security EEPROM (your

administrator password and startup sequence) will be protected from failure of the battery and CMOS memory.

 The security EEPROM will be protected from

unauthorized access because it locks after your server is turned on and the system programs have completed their startup routine. Once it is locked, the security EEPROM cannot be read from or written to by any software application or system software until the server is turned off and back on again. In a networking environment, this might prevent certain functions from being performed remotely on your server.

There is an extra measure of protection for the system programs in your server. Normally, the entire contents of the system programs EEPROM is write protected with a

soft lock

. A soft lock allows the POST/BIOS update utility to function in a network environment. Enhanced security adds a

hard lock

. With a hard lock, when your server is turned on and the system programs startup routine is completed, the POST/BIOS update utility is locked and cannot be unlocked until the server is turned off and back on again and the administrator password is entered. Note that in a networking environment this prevents the system programs in your server from being updated remotely. Someone must be present at your server to turn it on and off in order to unlock the POST/BIOS update utility.

 A chassis-intrusion feature will alert you if the cover of

your server has been removed. This feature will work if your server is on or off when the cover is removed. If the cover has been removed, a prompt for your administrator password will appear on the screen, and your server will remain in a halted state until your administrator password is entered.

 As with nonenhanced security, your configuration

settings are protected. The settings cannot be changed in the Configuration/Setup Utility program until your administrator password is entered. This means that any changes in server hardware that are detected by the system programs in your server, such as removal of a memory DIMM, will generate a

44 Netfinity Server HMM

configuration error until the administrator password is entered.

Enabling and disabling enhanced security:

Enhanced security can be enabled or disabled only when you update the system programs in your server.

To enable or disable enhanced security:

1. Insert a system programs update diskette into drive A in your server. System programs updates are available on the World Wide Web at http://www.ibm.com/pc/support/.

2. Turn on the server. If it is on already, you must turn it off and back on again.

3. The update begins, your server halts, and you are prompted for your administrator password (if you have set an administrator password). The server remains in a halted state until you enter the administrator password.

4. When you enter the administrator password, the update diskette will continue to run, and you are given the option of enabling or disabling enhanced security. Your choice is automatically recorded in the System Security menu of the Configuration/Setup Utility program.

Setting, changing, and deleting an administrator password protected by enhanced security:

set, change, or delete an administrator password protected by enhanced security, do the following:

1. Turn off all attached devices and the server.

2. Refer to “Disconnecting cables and removing the cover” on page 74 for instructions on safety, disconnecting all cables attached to the server, and removing the server cover.

3. Locate the switch marked as 7 on the rocker switches on the system board. Refer to the system board label inside the server for the location of the switch. Move the switch to the ON position. (To do this, push on the ON side.)

4. Replace the cover and reconnect the cables.

5. Set, change, or delete your administrator password in the Configuration/Setup Utility program. Refer to “Setting or changing an administrator password” on page 41 or “Deleting an administrator password” on page 42 for instructions.

Solving POST Error Message Problems

If you receive an error message during the power-on-self-test (POST), completing the steps outlined in this section might enable you to resolve the problem.

Note

If you have just added, removed, or changed the location of a device and you receive an error message, follow the procedure described in the Important text box on page 21. If the procedure on page 21 does not eliminate the error message, then proceed with the following instructions.

1. Write down all error code numbers and descriptions that appear on the screen as you start your computer. (Note that a single problem can cause several error messages to appear. When you correct the cause of the first error message, the other error messages probably will not appear on the screen the next time you turn on your computer.)

2. If you have set a power-on password, a password prompt appears. If you have set both power-on and administrator passwords, you can type either of the passwords at the password prompt. However, if you think you might need to change any settings in the Configuration/Setup Utility program, you must type your administrator password at the password prompt. If you type your power-on password, you will be able to view error codes and error code descriptions displayed on the POST Startup Errors screen, and you will also be able to view limited information in the Configuration/Setup Utility program. However, you will not be able to change any settings.

3. In the case of most errors, the Configuration/Setup Utility program starts automatically so that you can attempt to identify and correct the problem. When the Configuration/Setup Utility program starts, a screen titled POST Startup Errors appears. (Note that the POST Startup Errors screen does not appear immediately. You must wait approximately one minute.) If the POST Startup Errors screen does not appear, proceed to step 6.

4. At the POST Startup Errors screen, select Continue if you want to access the Configuration/Setup Utility program menu. Select Exit Setup if you want to exit the Configuration/Setup Utility program. (See the Important text box in step 5 for information on exiting the Configuration/Setup Utility program without making any changes to current settings.) To select an item, press Up Arrow (↑) or Down Arrow (↓) to highlight the item, and then press Enter.

5. If you selected Continue in step 4, the Configuration/Setup Utility program menu appears on

Netfinity 8655 - Type 8655

the screen. You will see a pointer next to any menu items that are malfunctioning or that have been changed since the last time you turned on your computer. If you did not knowingly make a change to a flagged menu item, there is probably a malfunction in that item. If you made a change, continue here. If you did not make a change, go to the Important text box which follows step 5d.

To use the Configuration/Setup Utility program, do the following:

a. Select the menu item that is flagged (or that you

wish to view) by pressing Up Arrow (↑) or Down Arrow (↓), and then press Enter.

b. A new menu specific to the item that you

selected appears. Press Left Arrow (←) or Right Arrow (→) to toggle between choices for a menu item. (Note that each menu item has a Help screen. To view the Help screen, select the menu item, and then press F1.)

c. When you have finished viewing and changing

settings, press Esc to return to the Configuration/Setup Utility program menu.

d. Before you exit from the program, select Save

Settings. When you exit from the Configuration/Setup Utility program menu (see step 5e), your operating system will start automatically (unless there is an unresolved problem with the startup device).

System management features

The following information is primarily for network administrators. It describes features that make it possible for a network administrator or file server to remotely manage and control your server.

The BIOS (basic input output system) of your server supports an interface called DMI (Desktop Management Interface). DMI is a method for gathering information about the hardware and software in a computer that makes it possible for network administrators to remotely monitor and control computers in a network environment. DMI can be used to remotely track many types of information about computers, including serial numbers, memory attributes, product-specific characteristics of installed peripherals, temperature, and operating-system configuration information. This information can be accessed using a DMI browser. DMI browsers are provided by all major operating systems and all major LAN management packages (including Netfinity Manager, Intel LANDesk and Microsoft SMS).

Your server has hardware integrated on the system board that provides system-management information to the DMI browser.

The following describes some of the other functions that can be performed on your server remotely.



Wake on LAN: The Wake on LAN feature can be

used by network administrators to turn on your server from a remote location. When Wake on LAN is used in conjunction with network management software, such as Netfinity Version 4 or later, many types of functions, such as data transfers, software updates, and POST/BIOS updates to your server can be initiated remotely. These functions can be performed after normal working hours and on weekends to save time, increase productivity, and help keep LAN traffic down during the busy hours of the day. Refer to “Using the Configuration/Setup Utility Program” on page 19 for configuration information.

Alert on LAN: Alert on LAN is a hardware and

software technology supported on some models of your server. It immediately alerts network administrators when the server has a problem, even if the power is off or has no operating system running. For system management, Alert on LAN helps the network administrator to react quickly and effectively when problems occur, rather than waiting for input from the end-user.

56 Netfinity Server HMM

RPL or DHCP: RPL (Remote Program Load) and

DHCP (Dynamic Host Configuration Protocol) enable a network administrator to control your server. If you use RPL in conjunction with software such as LANClient Control Manager, you can use a feature called

RPL

. Using LANClient Control Manager, you set up your computer by installing hybrid images (or files) on the hard disk. Then, each time the computer starts from the network, LANClient Control Manager recognizes your computer as a Hybrid RPL client and a is downloaded to your computer. This bootstrap program is small and helps prevent network congestion. Working from the hybrid images, the bootstrap program initiates the startup process from the hard disk of your computer. An advantage to Hybrid RPL is that the network load associated with standard RPL is avoided.

Working with microprocessors

Your server comes with an intel Pentium III microprocessor. This microprocessor incorporates MMX technology with built-in ECC L2 cache. For the latest information about microprocessor upgrades available for your server, contact your IBM reseller or IBM marketing representative. If you do upgrade the microprocessor, use the instructions that come with the upgrade along with the instructions in this section.

When you install an additional microprocessor, your Netfinity 3500 M10 server can operate as a symmetric multiprocessing (SMP) server. With SMP, certain operating systems and application programs can distribute the processing load between microprocessors. This can enhance performance for database applications, integrated manufacturing solutions, and other applications.

The voltage regulator function is built into the system board. This feature supports each microprocessor on the system board. If you install a second microprocessor, it must operate at the same voltage as the primary microprocessor to ensure proper operation of the voltage regulator feature.

Installing a second microprocessor

Attention

OS for SMP must be installed before the system will recognize a second microprocessor.

Before you begin

 Read “Safety Information” on page 196  Thoroughly review the documentation that comes

with the microprocessor, so that you can determine whether you need to update the server BIOS. ServerGuide includes IBM Update Connector, a dial-up program that keeps your BIOS and device drivers current. You also can obtain the latest level of BIOS for your server through the World Wide Web and the IBM PC Company Bulletin Board System (BBS). See “Online Support” on page iv for the appropriate World Wide Web addresses.

 Turn off the server.  Disconnect all cables attached to the server and

remove the server cover (see “Preparing to install and remove options” on page 73).

 Read “Accessing the system board” on page 82.

Netfinity 8655 - Type 8655 89

Attention

If you install an additional microprocessor that is different from the currently installed microprocessor, your server operation might be unreliable. To prevent this, use a microprocessor that is identical to the currently installed microprocessor (same internal and external clock speed, cache size, and voltage requirements).

To add a second microprocessor:

1. Read the instructions that come with the new microprocessor.

2. See “Identifying parts on the system board” on page 80 to locate the secondary microprocessor socket.

3. Remove the air baffle. See “Removing and replacing the air baffle” on page 82.

4. Remove the terminator card in the secondary microprocessor socket.

5. Touch the static-protective package containing the new microprocessor to any

7. Press the microprocessor down until it seats in the connector.

8. Reinstall the air baffle. See “Removing and replacing the air baffle” on page 82.

9. When you add a second microprocessor, it runs at the same speed as the primary microprocessor. For information on the appropriate switch settings, see the label inside the server cover, or contact your IBM reseller or IBM marketing representative.

10. The Configuration/Setup Utility program runs automatically after the server is restarted. If your operating system is configured to support multiple microprocessors, when the operating system starts it recognizes the second microprocessor. For Windows NT Server, for example, you might need to reinstall Windows NT Server and select multiple processor support before the second microprocessor will be recognized.

Before you begin

 Read “Safety Information” on page 196  Obtain a flash diskette for updating the system

BIOS. If you do not have a flash diskette, download one from http://www.ibm.com/pc/support/.

 Read the instructions that come with the new

microprocessor.

 Turn off the server.  Disconnect all cables attached to the server and

remove the server cover (see “Preparing to install and remove options” on page 73).

 Read “Accessing the system board” on page 82.

Attention

The microprocessor and heat sink might be hot if the server has been running. Let the microprocessor and heat sink cool for 10 minutes before continuing with the procedure.

The microprocessor in your server comes with an attached heat sink. The microprocessor plugs into the system board and is stabilized with a plastic bracket attached to the system board. To remove the microprocessor:

1. See “Identifying parts on the system board” on page 80 to locate the primary microprocessor socket.

2. Remove the air baffle. See “Removing and replacing the air baffle” on page 82.
