General checkout

This general checkout procedure is for Netfinity 1000 Type 8477 servers.

Attention

The drives in the system 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.

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.

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. 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.

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

4. If the server hangs with a POST error, go to “Symptom-to-FRU index” on page 162.

5. If the server hangs and no error is displayed, go to “Undetermined problems” on page 201.

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

7. If blank screen, unreadable screen, or other unusual response occurs, go to “Symptom-to-FRU index” on page 162.

8. For power supply problems, see “Power supply” on page 46.

Diagnostic test programs

IBM provides programs that you can run to diagnose hardware and some software problems. Several utility programs that provide helpful information about the server are also included. One of these programs provides the user interface for running these diagnostic and utility programs.

The server diagnostic test programs are stored on the

Enhanced Diagnostics CD

These programs are the primary method of testing the system board, memory, and other standard features of the Netfinity 1000 server. You can also use them to test some external devices.

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

The IBM Enhanced Diagnostics programs will isolate the server hardware from software that you have installed on the hard disk. The programs run independently of the operating system, and

diskette

. This method of testing is generally used when other methods are not accessible or have not been successful in isolating a problem suspected to be hardware related.

The server diagnostic test programs can identify most problems associated with major components of the server: the system board, Ethernet controller, video adapter or controller, random-access memory (RAM), CD-ROM, hard disk drive, diskette drive, serial port, parallel port, keyboard, and mouse.

In addition to the server test programs, the

Diagnostics CD

information about the server hardware, including the hardware configuration. This information might be useful in helping to isolate problems related to the operating system and device drivers.

IBM Netfinity 1000 - Type 8477

Power-on self-test (POST)

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

POST does the following:

 Checks the operation of some basic system-board

operations

 Checks the memory operation  Compares the current server configuration with the

stored server configuration information

 Configures PCI adapters  Starts the video operation  Verifies that the drives (such as the diskette,

CD-ROM, and hard disk drives) are connected properly

If Power-On Self-Test is set to [Enhanced], numbers that show 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. Options for running a quick POST or accessing the Configuration/Setup Utility program appear in the lower-left corner of the screen. Quick mode is the default mode of operation. To change the mode to [Enhanced], select Start Options from the Configuration/Setup Utility program menu and follow the prompts on the screen.

Note

The amount of available memory shown might be somewhat less than expected because of BIOS shadowing in RAM.

If POST finishes without detecting any problems, the first screen of the operating system or application program appears (if you have not set a power-on password). If you have set a power-on password, a password prompt appears. You must enter the password before the first screen of the operating system or application program will appear. (For further information on using passwords, see “System Security” on page 28.)

If Power-On Status is set to [Enabled] and POST detects a 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.)

8 Netfinity Server HMM

POST beep codes

If Power-On Status is set to [Enabled], POST also generates beep codes to indicate successful completion or the detection of an error.

 The startup of the operating system or application

program indicates successful completion of POST.

 More than one beep indicates that POST detected an

error.

For a list of beep codes, see “Symptom-to-FRU index” on page 162.

Error messages

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 indicated by error messages should be performed by a trained service technician.

Hardware error messages that occur can be text, numeric, or both. Messages generated by the software generally are text messages, but they also can be numeric.

POST error messages and beep codes

: POST error messages and beep codes occur during

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

For a list of error codes, see “Symptom-to-FRU index” on page 162.

SCSI error messages

: These messages appear if a problem or conflict is

detected by the SCSI subsystem. Refer to the SCSI documentation in the ServerGuide package that comes with the server for information about these messages.

Diagnostic error messages

: Diagnostic error messages occur when a test finds a

problem with the server hardware. The messages present text information that can be used to identify a failing part. These error messages are alphanumeric. Follow the instructions on the screen.

For a list of diagnostic codes, see “Symptom-to-FRU index” on page 162.

IBM Netfinity 1000 - Type 8477 9

Software-generated error messages

: These messages occur if a problem or conflict is

found by an 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.

Installing files from option diskettes

An optional device or adapter might come with a diskette. Diskettes that are included in option packages usually contain files that the system needs for recognizing and activating the options. Until you install the necessary files, the new device or adapter might cause error messages.

If the optional device or adapter comes with a diskette, you might need to install some configuration (.CFG) files or diagnostic files (.EXE or .COM) from the diskette to the hard disk. Refer to the documentation that comes with the option to see if you need to install files.

10 Netfinity Server HMM

Running the diagnostic test programs

Note

See “Diagnostic test programs” on page 7 for a description of the diagnostic programs that come with the server.

Attention

Do not discard the Enhanced Diagnostics CD. Store it in a safe place for later use.

To start the IBM Enhanced Diagnostics using the CD backup Diagnostic Diskette, do the following:

1. Power-off the server and any attached devices.

2. Insert the IBM Enhanced Diagnostics backup diskette into diskette drive A.

3. Power-on all attached devices; then, power-on the server.

4. Follow the instructions on the screen.

To make a backup copy of the IBM Enhanced Diagnostics information on a diskette, do the following:

1. Insert a blank, 3.5-inch, formatted 2 MB diskette into diskette drive A.

2. Boot the system with the Diagnostics CD in the CD-ROM drive.

3. Follow the instructions on the screen.

Power-on self-test (POST) messages

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, you must reconfigure the server. Follow the procedure described in “Configuration/Setup utility program menus” on page 25. If the procedure in “Configuration/Setup utility program menus” on page 25 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 the server. (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 that you power-on the server.)

2. If you have set a power-on password and have the password prompt set to On or Dual, a password

IBM Netfinity 1000 - Type 8477

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 the administrator password at the password prompt. If you type the power-on password, you will be able to view the error codes and error code descriptions that are displayed on the POST Startup Errors screen; 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 on page 13.

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 from the Configuration/Setup Utility program. (For more information on exiting from the Configuration/Setup Utility program, go to the Attention: section that follows step 5d on page 13.) To select an item, press the Up Arrow (↑) or Down Arrow (↓) key to highlight the item; then, press Enter.

5. If you selected Continue in step 4, the Configuration/Setup Utility program menu appears on the screen. You will see a pointer next to any menu items that indicate components that are malfunctioning or that have been changed since the last time you powered-on the server. If you did not knowingly make a change to a flagged component, that component is probably malfunctioning. If you made a change, continue here. If you did not make a change, go to the Attention: section that follows step 5d on page 13.

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

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

want to view) by pressing the Up Arrow (↑) or Down Arrow (↓) key; then, press Enter.

b. A new menu specific to the item that you

selected appears. Press the Left Arrow (←) or Right Arrow (→) key 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; then, press F1.)

12 Netfinity Server HMM

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), the operating system will start automatically (unless there is an unresolved problem with the startup device).

Attention

If you did

not

change any settings in the Configuration/Setup Utility program, note the following:

 You will get an error message if you

exit from the Configuration/Setup Utility program without selecting Save Settings. The operating system will not start, but the server will automatically restart. When the server restarts, you will get a POST error message, and then the Configuration/Setup Utility program will again start automatically.

 You will

not

get an error message if you select Save Settings and then exit from the Configuration/Setup Utility program. The system will save all settings as they currently appear in the Configuration/Setup Utility program, and the operating system will start (unless there is an unresolved problem with the startup device).

e. To exit from the Configuration/Setup Utility

program, press Esc and follow the instructions on the screen.

6. For more information about error messages see “Symptom-to-FRU index” on page 162.

Configuration overview

You play a key role in how the server allocates resources to organize and interconnect hardware devices and software programs. This allocation process is referred to as

configuration.

server depend on the number and types of devices and programs that you install.

The server has connectors for several types of adapters. Because of this flexibility, you can choose from among thousands of adapters and devices that comply with any of the following standards:

 Peripheral Component Interconnect (PCI)  Industry Standard Architecture (ISA)  Small Computer System Interface (SCSI)  Accelerated Graphics Port (AGP)

You can obtain a listing of products that are compatible with the server, and related configuration information, by accessing the following World Wide Web address:

http://www.ibm.com/pc/us/compat/

Jumpers and switches are used to define certain configuration values on the system board, adapters, and other devices. If you need to set jumpers or switches on adapters, drives, or other devices, refer to the documentation that comes with the devices for specific information about the appropriate jumper and switch settings.

In general, the greater the number and variety of hardware devices and software programs that you install in the server, the more you will have to interact with the server and the devices to correctly configure the system.

The server comes with the following hardware configuration utility programs:

 Configuration/Setup Utility program

With the Configuration/Setup Utility program, you can configure system board functions, such as serial and parallel port assignments; change interrupt request settings; and change the startup sequence for drives that you install. You can also use this utility program to set passwords for starting the server and accessing the Configuration/Setup Utility program.

 SCSISelect Utility

With the built-in SCSISelect Utility program, you can configure the SCSI devices that you install in the server. You can use SCSISelect to change default values, resolve configuration conflicts, and perform a low-level format on a SCSI hard disk drive.

Before installing a new device or program, read the documentation that comes with it. Reading the instructions

The steps required to configure the

IBM Netfinity 1000 - Type 8477

helps you to determine the steps required for installation and configuration. The following actions are typically, but not always, required to configure the server.

1. Run the Configuration/Setup Utility program and record the current configuration settings.

See “Configuration/Setup utility program” on page 22.

2. Power-off and unplug the server.

3. Set jumpers or switches on the server's system board.

4. Set jumpers or switches on the device. See the device installation instructions.

5. Install the device in the server. Reserve ISA legacy resources for ISA adapters. See

“ISA Legacy Resources” on page 37.

6. Resolve configuration conflicts. See “Configuration conflicts” on page 21.

7. Install software programs, including device drivers. Refer to the information that comes with the IBM

ServerGuide package for more information.

20 Netfinity Server HMM

Configuration conflicts

The resources used by your server consist of IRQs, DMA, I/O port addresses, and memory. This information is useful when a resource configuration conflict occurs.

Conflicts in the configuration occur if:

 A device that you installed requires the same

resource as another device. (For example, a conflict occurs when two adapters try to write to the same address space.)

 A device resource is changed (for example, changing

jumper settings).

 A device function is changed (for example, assigning

COM1

to two serial ports).

 A software program is installed that requires the same

resource as a hardware device.

The steps required to resolve a configuration error are determined by the number and variety of hardware devices and software programs that you install. If a hardware configuration error is detected, a message appears after the server completes POST and before the operating system is loaded. You can bypass the error by pressing Esc while the error message is displayed.

The Configuration/Setup Utility program configures only the system hardware and interrupt requests. The program does not consider the requirements of the operating system or the application programs. For these reasons, memory-address configuration conflicts might occur. You can resolve some memory-address conflicts by changing the address of the conflicting hardware option, or by changing or moving the hardware. You might have to resolve other memory-address conflicts by changing some software parameters. See “Hardware configuration conflicts” and “Software configuration conflicts” on page 22, respectively, for additional information.

configuration error

Hardware configuration conflicts

: Use the following information to help resolve hardware

configuration conflicts:

1. Run the Configuration/Setup Utility program to view and change the resources that the system board functions use. Record the current settings before making any changes. (See “Configuration/Setup utility program” on page 22 for instructions.)

2. Determine which adapter or device is causing the conflict.

3. Change adapter jumpers or switches. Some devices use jumpers and switches to define the system resources that they need. If the settings are incorrect or set to use a resource that cannot be shared, a

IBM Netfinity 1000 - Type 8477

conflict occurs, and the device will remain deactivated by the configuration program.

4. Change system board jumpers or switches. Then, refer to the system-board diagram inside your server.

5. Remove the device or adapter. Some configurations are not supported. If you must remove an adapter, see “Installing or removing ISA and PCI adapters” on page 63.

Software configuration conflicts

: The Configuration/Setup utility might change the

memory-address space used by some hardware options. If this happens, the new memory-address space and IRQs used by some hardware options might conflict with addresses defined for use through application programs.

If a conflict exists, one or more of the following conditions might exist:

 The system cannot load the operating system.  The system does not work.  An application program does not operate, or it returns

an error.

 Screen messages indicate that a memory-address

conflict exists.

Note

Start the Configuration/Setup Utility program to view the addresses that are used by your system board functions.

The best way to resolve memory-address conflicts is to change the addresses that are used by the application program or the device driver. You can use the Configuration/Setup Utility program to view and change addresses.

Configuration/Setup utility program

For most configurations, the server will operate using the default system settings. You need to change the settings only to resolve configuration conflicts or to enable or change device functions.

When you want or need to change the default settings, the Configuration/Setup Utility program provides a convenient way to display and change the settings.

After you run and exit the Configuration/Setup Utility program, configuration information is stored in electrically erasable programmable read-only memory (EEPROM). While the server is powered off, the configuration information remains available for the next system startup.

Always run the Configuration/Setup Utility program if you receive an error message instructing you to do so. If you installed or removed SCSI devices, run the SCSISelect

22 Netfinity Server HMM

Utility program (see “SCSISelect utility program” on page 50). Review the information that comes with the option before making changes.

When you restart the server for the first time after working with most options, a message appears, indicating that a configuration change has occurred. You are then prompted to enter the Configuration/Setup Utility program to manually update the configuration settings or to confirm and save the settings that were automatically updated by the system programs.

After you change an option and restart the server, the following screen might appear.

POST Startup Error(s)

The following error(s) were detected when the system was

started:

Depending on the configuration changes that occurred, the error message that you see might be different from the one shown here.

If the preceding screen appears, select Continue until you reach the Configuration/Setup Utility program menu; then, go to “Configuration/Setup utility program menus” on page 25.

If the preceding screen does not appear, use the following procedures to access the Configuration/Setup Utility program menu.

To start the Configuration/Setup Utility program:

1. Power-on the server and watch the screen. If the server is already turned on, power-off the

server, wait a few seconds until all in-use lights go off, and then power the server back on. (Do not use Ctrl+Alt+Del to restart the server.)

2. When the message Press F1 to enter Configuration/Setup appears, press F1. The Configuration/Setup Utility program menu appears. For information about the menus, see “Configuration/Setup utility program menus” on page 25.

System Security

: Several security features are available to help you

secure the server and the information that you store in it. To control access to the server, you can implement the security features, such as adding passwords, and securing IDE devices and diskette drives.

Setting power-on password modes

The power-on password can deter unauthorized access to the system. You do not need to set a power-on password, but doing so allows you to control who can use the server. When a power-on password is set, you must type the password at a prompt that appears as the server starts.

When you set the power-on password, you can choose one of three password prompt modes.

In password prompt On mode, you are prompted for the power-on password when you power-on the server. Until you enter the correct password, the operating system will not start, and the keyboard will remain locked. If you have a mouse connected to the mouse port, the mouse also will remain locked until you enter the power-on password. If you have a mouse connected to a serial port, it will be activated when the server is started, regardless of whether a password is set.

Note

If Remote Administration is enabled, you cannot select On. In this case, select Dual.If the power-on password mode is set to On when Remote Administration is enabled, it resets automatically to Dual.

Off

In password prompt Off mode (sometimes referred to as unattended start mode), you are not prompted to enter the power-on password when you power-on the server. The server will start the operating system.

28 Netfinity Server HMM

However, if you have a mouse connected to the mouse port, refer to the following text box.

Important Information for Mouse Users

This information applies only to those who 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, in this mode, the mouse device driver will not be loaded automatically through the CONFIG.SYS or AUTOEXEC.BAT files, an error message will appear to indicate that the mouse port is disabled, and the server will halt. To enable the operating system to load without displaying the error message, follow the instructions that apply to the operating system.



If you are using OS/2

, do one of the following

before enabling password prompt Off mode:

 Set the CONFIG.SYS file so that the

operating system does not stop on a device-driver error. To do this, put the command PAUSEONERROR=NO near the top of the CONFIG.SYS file.

 Remove the mouse driver statement from

the CONFIG.SYS file.

If you are using Windows NT or Windows 95, do the following:

 When the server is started and the mouse

port disabled error message appears, type either the 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 the 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.

Password prompt Off mode is useful for network servers and other servers that operate unattended. If a power failure occurs, the server will automatically

IBM Netfinity 1000 - Type 8477

restart and resume operating in this mode when power is restored, without operator intervention.

If you enter a password, the keyboard will unlock, but the mouse connected to the mouse port will remain disabled.

Password prompt Off mode is useful for network environments that cause the server to operate unattended. If a power failure occurs, when power is restored, the server will automatically restart and resume operating in this mode, without operator intervention.

Dual

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

If you press the power switch to start the server, the server operates the same as it does in password prompt On mode.

If you start the server by an unattended method, such as remotely over a LAN, the server operates in password prompt Off mode.

If both a power-on and administrator password are set, you can type either password at the password prompt

The password does not appear on the screen as you type it. If you type the wrong password, you receive a screen message telling you so. If you type the wrong password three times, you must power the server off and start again. When you type the correct password, the keyboard and mouse will unlock, and the server will begin normal operation.

If both a power-on and administrator password are set, you can enter either password to complete the system startup. However, the administrator password provides access to all menu choices, and provides the ability to change information. If you enter the power-on password, you can view limited information in the Configuration/Setup Utility program, but you cannot change any settings.

Using the Enhanced Security features

With enhanced security, the administrator password and drive-startup sequence are stored in a highly protected, nonvolatile, security EEPROM module. When the administrator password and drive-startup sequence are stored in the security EEPROM, they remain intact even if the battery expires or is removed.

Attention Administrator Password Users:

If enhanced security is enabled, and you forget or lose the administrator password, you must replace the system board in the server to regain access to the Configuration/Setup Utility program.

If enhanced security is enabled and you have set an administrator password, the server will operate as follows:

 The security EEPROM is protected from unauthorized

access once the startup procedures are complete. With enhanced security disabled, the contents of the

EEPROM are write protected, and the server can function in a network environment because the POST/BIOS utility program will allow updates to the system programs.

With enhanced security enabled, the POST/BIOS utility program will not allow updates to the system programs. In a network environment, this might prevent certain functions from being performed remotely.

 If the cover of the server has been removed, a

tamper-detection feature will halt system processing and deny access to the keyboard and mouse until the administrator password is entered. This feature will work if the server is powered on or off.

To enable or disable enhanced security:

IBM Netfinity 1000 - Type 8477

Note

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

1. Insert the POST/BIOS update diskette in the server. System programs updates are available on the World Wide Web. To obtain up-to-date information about the server model, access the home page for the server at the following address:

http://www.ibm.com/netfinity/

2. Power-on the server. If it is already powered on, you must power it off and back on again.

3. The update begins, and the system prompts you for the administrator password, if you have set an 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.

To set, change, or delete an administrator password protected by enhanced security:

1. Power-off all attached devices and the server.

2. Disconnect all cables, and remove the server cover.

3. Locate the switch marked as 7 on the rocker switches section of the system board. See “Administrator password switch setting” on page 144 for the location of the switch. Move the switch to the ON position. (It might be helpful to use the end of a small screwdriver to set the switch.)

Note

You must know the administrator password to change or delete it.

4. Set, change, or delete the password. Follow the instructions on the screen. (See “Using the Administrator Password menu” on page 32.)

5. Move the switch back to the OFF position after you have set, changed, or deleted the password.

6. Replace the cover. Then, power-on the server.

Restricting access to IDE devices and diskette drives

The setting for the Secure IDE and Diskette Drives option controls who has access to the IDE devices and diskette drives (user and administrator, or administrator only). The server comes with this feature set to Enable, so that both the user and administrator have access to the IDE devices and diskette drives.

expanding the server easier. Support for Plug and Play is built into the system board of the server.

If an adapter is Plug and Play, there are no switches or jumpers that must be set on the adapter. A Plug and Play adapter comes with configuration specifications set in memory to provide installation information to the server during startup. When you install or remove Plug and Play adapters, this information is interpreted by the BIOS, which supports Plug and Play technology. If the required resources are available, the BIOS software automatically configures the adapter around the resources already in use by other devices.

Most adapters designed for PCI slots are Plug and Play devices that are auto-configuring. However, many ISA adapters are not Plug and Play devices. These adapters are known as adapter, you must manually configure it by setting switches or jumpers on the adapter, and by allocating or reserving the system resources that the adapter will use.

Configuring the Ethernet controller

The Netfinity 1000 server comes with an Ethernet controller on the system board. The Ethernet controller provides 10BASE-T and 100BASE-TX support through the RJ-45 connector on the back of your server. When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate. That is, the Ethernet controller 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). This process is also known as auto-negotiation. This auto-negotiation occurs without requiring software intervention. The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

However, auto-negotiation works only if the hub or switch to which your server is connected also supports auto-negotiation. If the hub or switch does not support auto-negotiation, the speed (10 Mbps or 100 Mbps) will still be detected correctly, but half-duplex mode will always be selected. A full-duplex switch that does not support auto-negotiation will not attach to the Netfinity 1000 server in full-duplex mode. In this case, if you want the network to operate in full-duplex mode, you must manually override the settings to obtain a full-duplex connection. To do this, your server must have a device driver that supports manual overrides. Use ServerGuide to install this device driver. Refer to your ServerGuide package for instructions on installing device drivers. ServerGuide includes IBM Update Connector, which keeps your BIOS and device drivers current. Verify that you have installed the appropriate device driver. Also, refer to your Ethernet documentation for additional information on operating modes, manual overrides, and device drivers.

Attention

 The 10BASE-T Ethernet and the 100BASE-TX

Fast Ethernet cabling in the network must be Category 5 to meet various standards, including electromagnetic compatibility.

 You must install a device driver to enable your

operating system to address the Ethernet controller. Use ServerGuide to install this device driver. Refer to the ServerGuide package for instructions on installing device drivers.

Fast Ethernet operates at a data rate of up to 100 Mbps. However, except for the different operating speeds, Fast Ethernet and standard Ethernet are structurally identical. Most applications and protocols that are currently installed on a standard Ethernet system can be seamlessly migrated to a Fast Ethernet system. Because of the

IBM Netfinity 1000 - Type 8477

equivalence of the two types of Ethernet, mixed Ethernet and Fast Ethernet systems also can be designed and implemented.

The bandwidth required at each workstation connected to a server is generally far less than the bandwidth required at the server. This is because the server might have to handle the bandwidth of multiple workstations at the same time. A cost-effective solution to the bandwidth requirements of this type of system is a mixed Ethernet and Fast Ethernet network. This mixed network consists of standard Ethernet connections at the workstations and Fast Ethernet connections at the servers.

The Ethernet controller is a PCI device, and is therefore, a Plug and Play device. You do not have to set any jumpers or configure the controller for your operating system before you use the Ethernet controller.

Network connection problems:

controller cannot connect to the network, check the following:

1. Make sure that the cable is installed correctly. The network cable must be securely attached at all

connections. If the cable is attached but the problem persists, try a different cable.

If you use the integrated Ethernet controller, you must use Category 5 cabling. See “Specifications (Ethernet cable)” on page 54 for additional information about Ethernet cable requirements.

If you directly connect two workstations (without a hub), or if you are not using a hub with X ports, use a crossover cable. See “Specifications (Ethernet cable)” on page 54 for an illustration of a crossover cable.

Note

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

2. Check the Ethernet activity light on the front of the server.

The Ethernet activity light comes on when the Ethernet controller sends or receives data over the Ethernet network.

Note

This light is off when you run the diagnostic programs in the Configuration/Setup Utility program.

If the Ethernet

Specifications (Ethernet cable)

This appendix contains the specifications for the unshielded twisted-pair (UTP) cables that can be used to connect the server to an IEEE Standard 802.3 network.

The Ethernet controller on your system board provides 10BASE-T and 100BASE-TX support through the RJ-45 connector on the back of your server. When you connect your server to the network, the Ethernet controller automatically detects the data-transfer rate (10 Mbps or 100 Mbps) on the network and then sets the controller to operate at the appropriate rate.

The following information describes the specifications for the unshielded twisted-pair (UTP) cable that can be used to connect the server to an IEEE Standard 802.3 network.

Attention:

To connect the server's 10BASE-T or 100BASE-TX port to a repeater, use an UTP EIA/TIA-568 Category 5 cable that is terminated with RJ-45 connectors. This is a requirement to meet various governmental standards, including electromagnetic compatibility.

The cables used in 10BASE-T or 100BASE-TX link segments do not require grounding. However, all devices connected to the cables must be grounded.

Connect the appropriate type of UTP cable to the repeater.

 If the port on the repeater is a crossover port (also

called an MDI-X port), use a UTP cable that is wired as a straight-through cable.

 If the port on the repeater is not a crossover port

(also known as an MDI port), use a UTP cable that is wired as a crossover cable.

The server contains three diagnostic light-emitting diodes (LEDs) for the Ethernet connector, one located on the front and two located on the rear of the ssrver.

 When the green LED is on, it indicates that the

Ethernet controller is connected to a hub or switch and is receiving link pulses. This LED is also known as the Link OK light.

 When the amber LED is on, it indicates that the

Ethernet network is operating at 100 Mbps. When this LED is off, it indicates that the Ethernet network is operating at 10 Mbps.

Do not use telephone extension cables to connect the server to a repeater. The wire pairs in those cables are not twisted, and the cables do not meet other requirements for use in a 10BASE-T or 100BASE-TX network. You can identify telephone extension cables by their flat and thin appearance. UTP cables are rounder and thicker than telephone extension cables.

54 Netfinity Server HMM

Table 1 on page 55 describes the specifications for UTP cables used in 10BASE-T and 100BASE-TX link segments. Cables for these link segments must be certified as EIA/TIA-568 Category 5.

Notes:

1. Cables that have been certified as EIA/TIA-568 Category 5 meet all 10BASE-T and 100BASE-TX specifications. An EIA/TIA-568 Category 5 cable must be used for 10BASE-T and 100BASE-TX.

2. The cable can contain two to four twisted pairs, but only two of the pairs will be used by the 10BASE-T or 100BASE-TX network.

3. The c represents the velocity of light traveling in a vacuum, which is 300000 km/sec (186400 mi/sec).

Accessing the system board

Before you can install or remove certain options, you might need to access the system board. For example, you might need to remove adapters, drives, and cables that impede your access to components on the system board. You also need to access the system board before you can install or remove such options as adapters, memory modules, and microprocessors, because these devices reside on the system board.

To access the system board more easily:

1. Rotate the stabilizer feet in towards the server, so that they do not detach due to the weight of the server.

2. Place the server on a flat, sturdy surface, such as a table.

3. Turn the server on its side, so that the system board is facing you.

If you access the inside of the server while it is in the upright position, ensure that the stabilizer feet are positioned correctly. For more information, see “Stabilizing feet” on page 137.

Note

To see a list of the system-board components and an illustration that shows their locations, see “System board illustration” on page 141.

Adapters

Adding an adapter, such as a communication adapter, extends the capabilities and power of the server. For example, if the server supports redundant array of independent disks (RAID) technology, you can add a RAID adapter that can enhance logical-drive capacity and performance.

Note

For a complete list of the adapters that the server supports, go to http://www.ibm.com/pc/us/compat/ on the World Wide Web, or contact an IBM marketing representative.

When you are installing or removing adapters, it is important to resolve any resource conflicts that might arise. For example, if you install an ISA legacy adapter, you might need to manually configure the adapter by setting a variety of switches on the adapter and by using the Configuration/Setup Utility program.

Many adapters now use enables the server to automatically configure the adapter, provided that the required resources are available. Refer to the instructions that come with the adapter to determine if it is Plug and Play. For more information, see “ISA Legacy Resources” on page 37.

Adding security options

Security features can help to protect the server data and programs from unauthorized access and use, and help to physically protect the server from theft and tampering. After you determine the system security needs, you can activate or implement the appropriate security features.

To control access to the information in the server databases, you can implement security measures through the system configuration programs. These features include defining two levels of password protection, restricting diskette access, and defining a system owner's name. Implementing these security measures helps you to ensure the integrity of the data and programs that are stored in the server. See “System Security” on page 28 for details.

To prevent writing to a diskette in a diskette drive, set the diskette write-protect switch, as described in “Diskette write-protect switch setting” on page 146.

To erase lost or forgotten passwords, you can move the CMOS clear (password) jumper on the system board.

To control access to other hardware components in the server, you can install several types of optional devices. These options include:

 U-bolt  Security cable  Padlock

The following section discusses these security options.

Installing a U-bolt and security cable: You

can help to deter unauthorized removal of the Netfinity 1000 server by installing a U-bolt and security cable on the rear of the server. After you add the security cable, make sure that it does not interfere with other cables that are connected to the server.

Disconnecting cables and removing the side cover

Attention

The presence of 5 V ac standby power might result in damage to the hardware unless you disconnect the power cord from the electrical outlet before you open the server.

1. Remove any media (diskettes or CDs) from the drives; then, power-off all attached devices and the server.

Caution

The Power Control button on the front of the server does not turn off the electrical current supplied to the server. The server also might have more than one power cord. To remove all electrical current from the server, ensure that all power cords are disconnected from the power source.

2. Touch the rear of the bare metal frame to dissipate any static electricity from your body.

3. Before disconnecting cables, be sure to note where they attach, so that you can correctly reattach them later.

Note

If you are in the United Kingdom, you must perform step 5 before step 4.

4. Unplug all power cords (cables) from electrical outlets.

5. If you have a modem or fax machine attached to the server, disconnect the telephone line from the wall outlet and the server.

6. Note the location of the remaining cables and cords.

IBM Netfinity 1000 - Type 8477

Caution.

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

7. Disconnect all cables attached to the server; this includes power cords, input/output (I/O) cables, and any other cables that are connected to the server.

Notes

External options

Some examples of the external options that you can connect to the server include SCSI drives and storage enclosures, printers, modems, and other serial and parallel devices.

To attach an external option:

1. Power-off the server and all attached devices.

2. Follow the instructions that come with the option and the information in this section to connect it to the server.

The information in this section supplements the instructions that come with the external option. Use the instructions that come with the option to prepare it for installation.

Adding a hot-swap storage expansion enclosure: You can connect a storage enclosure to

the external SCSI connector on the separately installed SCSI adapter. Contact your IBM reseller or IBM marketing representative for additional information.

External SCSI devices

Note

If an internal device(s) is/are attached to the SCSI controller, only one external device is supported.

The internal SCSI connector provides support for SCSI devices installed inside the server. The external SCSI connector provides support for external SCSI devices. The UltraSCSI adapter can support a maximum of 15 devices.

Notes

 If you plan to install both internal and external

SCSI devices, you must follow the instructions given in “Internal drives” on page 98 in addition to the instructions in this section. Read “Internal drives”; then, return here.

For additional information about SCSI configurations supported, see http://www.ibm.com/netfinity/

 The server comes with a wide (16-bit) SCSI

cable that supports 16-bit devices. If you want to attach narrow (8-bit) devices to the server, you must purchase a SCSI 68-pin to 50-Pin Converter that will enable the connection of the device to the cable that comes with the server.

 It is good practice not to exceed the following

cable-length guidelines:

– If you connect one or more UltraSCSI

devices to the UltraSCSI adapter, do not exceed 1.5 meters (5 feet) total length for all cables (internal and external).

– If you connect only Fast SCSI devices to the

UltraSCSI adapter, do not exceed 3 meters (10 feet) total length for all cables (internal and external).

Attention

In addition to cable length and the number of installed devices, you must consider other factors that limit the performance of the SCSI subsystem. For example, if you install UltraSCSI devices in an external expansion enclosure that is limited to Fast transfer rates, or if you exceed the previously described cable-length guidelines, the transfer rate to all SCSI devices must be limited to Fast or standard transfer rates. You accomplish this by using the SCSISelect Utility program. See “SCSISelect utility program” on page 50 for additional information.

If you plan to attach an external SCSI device, you must order an additional SCSI cable. That is, to use an external

IBM Netfinity 1000 - Type 8477

device with the Netfinity 1000 server, you must connect it to the external SCSI connector, using a SCSI cable. This SCSI cable must have the proper connector for the SCSI external connector on one end, and the proper connector for the external device on the other end. To select and order the correct SCSI cable for use with the external device, contact your IBM reseller or IBM marketing representative.

Serial port connectors: Serial ports are used to

communicate with printers, plotters, external modems, auxiliary terminals, and other computers. The server provides two serial ports (1 and 2). You can add more serial ports by installing a serial adapter in one of the expansion slots.

Serial ports transfer data

asynchronously

transmit any number of bits at any time, with no restriction on the duration of the pauses between characters.

The serial ports transmit and receive data and commands at a rate of 300 bits per second (bps) up to 115200 bps. The bits-per-second measurement is commonly referred to

baud rate.

as the Both of the serial connectors on the server use a 9-pin,

Parallel port connector: Parallel ports are used to

communicate with printers and other devices, such as some CD-ROM and tape drives. The server provides one 25-pin, D-shell connector on the back of the server.

This parallel port connector conforms to the Institute of Electrical and Electronics Engineers (IEEE) Standard 1284. There are three standard modes of operation:

 Standard Parallel Port (SSP)  Enhanced Parallel Port (EPP)  Extended Parallel Port (ECP)

Table 3 shows the pin-number assignments for the parallel port connector. The signal names for all three modes are shown. SSP and ECP signal names are the same; EPP signal names that are different are shown in parentheses.
