What Your IBM Netfinity 5000 Server Offers

The IBM Netfinity 5000 server is designed to be cost effective, powerful, and flexible. Your server offers:

 Impressive performance using an innovative approach to SMP

The Netfinity 5000 server supports up to two Pentium II microprocessors. Your server comes with one Pentium II microprocessor installed on the system board. You can install a second microprocessor in your server to enhance performance and provide SMP capability.

 Large system memory

The memory subsystem in your server supports up to 1GB1 of system memory. The memory controller provides error correcting code (ECC) support for 100 MHz SDRAM memory.

 Integrated network environment support

Your server supports various network environments. Your Netfinity 5000 server comes with a 10/100 Mbps 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. Full duplex allows simultaneous transmission and reception of data on the Ethernet local area network (LAN).

 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.

 Redundant power capabilities

The 350-watt power supply in your server provides redundant power. If your server load is less than 175 watts and a problem occurs with one of the power modules in the power supply, the other module takes over the load. For power loads above 175 watts, you can install a second, optional, power supply to provide a full 350 watts of redundant power. If a problem occurs in either power module in the primary power supply, the second power supply takes over the load for that module.

 System-management capabilities

Your Netfinity 5000 server is shipped with a Netfinity Advanced System Management Processor on the system board. This processor, in conjunction with the Netfinity Manager provided on your ServerGuide CDs, allows you to manage the functions of the Netfinity 5000 server locally and remotely. The Advanced System Management processor also provides system monitoring, event recording, and dial-out alert capability.

Note: The Advanced System Management processor is sometimes referred to

Arranging Your Workspace

To get the most from your server, arrange both the equipment you use and your work area to suit your needs and the kind of work you do. Your comfort is of foremost importance, but light sources, air circulation, and the location of electrical outlets also can affect the way you arrange your workspace.

Comfort

Although no single working position is ideal for everyone, here are a few guidelines to help you find a position that suits you best.

Sitting in the same position for a long time can cause fatigue. A good chair can make a big difference. The backrest and seat should adjust independently and provide good support. The seat should have a curved front to relieve pressure on the thighs. Adjust the seat so that your thighs are parallel to the floor and your feet are either flat on the floor or on a footrest.

When using the keyboard, keep your forearms parallel to the floor and your wrists in a neutral, comfortable position. Try to keep a light touch on the keyboard and your hands and fingers relaxed. You can change the angle of the keyboard for maximum comfort by adjusting the position of the keyboard feet.

Arranging Your Workspace

Adjust the monitor so the top of the screen is at, or slightly below, eye level. Place the monitor at a comfortable viewing distance, usually 51 to 61 cm (20 to 24 in.), and position it so you can view it without having to twist your body. Also position other equipment you use regularly, such as the telephone or a mouse, within easy reach.

Glare and Lighting

Position the monitor to minimize glare and reflections from overhead lights, windows, and other light sources. Even reflected light from shiny surfaces can cause annoying reflections on your monitor screen. Place the monitor at right angles to windows and other light sources, when possible. Reduce overhead lighting, if necessary, by turning off lights or using lower wattage bulbs. If you install the monitor near a window, use curtains or blinds to block the sunlight. You might have to adjust the Brightness and Contrast controls on the monitor as the room lighting changes throughout the day.

Lower Back Support

Seat Height

Viewing Distance

Where it is impossible to avoid reflections or to adjust the lighting, an antiglare filter placed over the screen might be helpful. However, these filters might affect the

Arranging Your Workspace

clarity of the image on the screen; try them only after you have exhausted other methods of reducing glare.

Dust buildup compounds problems associated with glare. Remember to clean your monitor screen periodically using a soft cloth moistened with a nonabrasive liquid glass cleaner.

Air Circulation

Your server and monitor produce heat. Your server has one or more fans that pull in fresh air and force out hot air. The monitor lets hot air escape through vents. Blocking the air vents can cause overheating, which might result in a malfunction or damage. Place the server and monitor so that nothing blocks the air vents; usually, 51 mm (2 in.) of air space is sufficient. Also, make sure the vented air is not blowing on someone else.

Electrical Outlets and Cable Lengths

The location of electrical outlets and the length of power cords and cables that connect to the monitor, printer, and other devices might determine the final placement of your server.

When arranging your workspace:

 Avoid the use of extension cords. When possible, plug the server power cord

directly into an electrical outlet.

 Keep power cords and cables neatly routed away from walkways and other

areas where they might get kicked accidentally.

For more information about power cords, see “Power Cords” on page 174 or refer to the “Legal and Safety Information” section of this

Additional Planning Considerations

 Make sure you have an adequate number of properly grounded electrical

outlets for your server, monitor, and any other options that you intend to install.

CAUTION: When the power-cord strain-relief bracket option is installed on the power cord, the server must be plugged to a power source that is easily accessible.

 Place your server in a location that is dry. Rain or spilled liquids might damage

your server.

Server Library

 Leave about 127 mm (5 in.) of space around the front and rear of your server

to allow the server's cooling system to work properly.

Configuration Overview

You play a key role in how your server allocates resources to organize and interconnect hardware devices and software programs. This allocation process is referred to as the number and types of devices and programs that you install.

Your server supports 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)

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

Your server comes with the following hardware configuration utility programs:

configuration

Configuration Overview

. The steps required to configure your server depend on

 Configuration/Setup Utility

With the built-in 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 up 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 your 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 helps you determine the steps required for installation and configuration. The following actions are typically, but not always, required to configure your server.

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

2. Set switches on the server system board. See “System Board Switches” on page 170 for the meanings of the system

board switches.

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

4. Install the device in the server. See Chapter 4, “Installing Options” on page 39.

5. Install software programs. Refer to the information provided with the “ServerGuide and Netfinity Manager

Information” section of this more information.

Server Library

and with your operating system for

The Configuration/Setup Utility

6. Resolve configuration conflicts. See “Resolving Configuration Conflicts” on page 30.

The Configuration/Setup Utility

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 nonvolatile random-access memory (NVRAM). 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 add or remove any hardware option, or if you receive an error message instructing you to do so. Review this chapter and the information that comes with the option before making changes. Also, record the current settings (see Chapter 7, “Server Records and Specifications” on page 161) before making any changes.

To start the Configuration/Setup Utility program:

1. Turn on the server and watch the screen.

2. When the messages Press F1 for Configuration/Setup and Press F2 for

Diagnostics appear, select the action you need.

 To configure your server, press F1 to select Configuration/Setup Utility.

The Configuration/Setup Utility main menu appears. For information about the menus, see “Using the Configuration/Setup Utility” on page 22.

Devices and I/O Ports

Software recognizes ports from their port assignments. Each port must have a unique port assignment. The Configuration/Setup Utility program normally handles this, but you might have special hardware or software that requires you to change these assignments.

Note: Serial port A can be shared by the system-management processor and

operating system. Serial port B is used by the operating system only. Management port C is controlled exclusively by the system-management processor, cannot be used by the operating system, and cannot be configured using the Configuration/Setup Utility program. See the “Advanced System Management Information” section of this for information about configuring serial ports A and C.

Select the Devices and I/O Ports choice to view or change the assignments for devices and input/output ports.

You can add serial ports by installing a serial adapter in an expansion slot. See the documentation that comes with the serial adapter for information about port assignments.

You can configure the parallel port as standard, as bidirectional, as an Extended Capabilities Port (ECP), or as an Enhanced Parallel Port (EPP). Bidirectional, ECP, and EPP are all bidirectional modes; in all three modes, data can be both read from and written to a device. ECP and EPP are industry-standard, high-performance bidirectional modes. Which one of these modes you choose depends on what mode your device supports.

Note: When you configure the parallel port as bidirectional, ECP, or EPP, use an

IEEE 1284-compliant cable. The maximum length of the cable must not exceed 3 meters (9.8 feet).

Error Log

Resolving Configuration Conflicts

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 and you must allocate the system resources that the adapter will use. Select Plug and Play to identify the available system resources:

 Memory  I/O ports  DMA  Interrupt

Note: The menus do not contain resources that are used by the system or by

previously installed Plug and Play adapters.

Select Plug and Play; then, use the Up Arrow (↑) and Down Arrow (↓) key to highlight the system resource that you want to change. Use the Left Arrow (←) or Right Arrow (→) key to toggle from Plug and Play to ISA Legacy for the selected menu choice.

Select Error Log to view the three most recent power-on self-test (POST) errors the system has generated, or to view the system error log. You can clear both error logs from this screen by selecting Clear Error Logs.

Configuring PCI Features and Options

PCI devices automatically communicate with the server configuration information. This usually results in automatic configuration of a PCI device. If a conflict does occur, see “Resolving Configuration Conflicts.”

Multiple-function PCI adapters use more than one interrupt. When you install one of these adapters, review the IRQ assignments in the Configuration/Setup utility programs (see “PCI Bus Control” on page 29). Verify that the IRQ assignments are correct.

Your Netfinity 5000 server uses a rotational interrupt technique to configure PCI adapters. This technique enables you to install a variety of PCI adapters that currently do not support sharing of PCI interrupts. For information on manually overriding the interrupt setting, see “PCI Bus Control” on page 29.

Resolving 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 is installed that 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

30 Netfinity 5000 Server Hardware Information and Procedures

COM1

to two serial ports).

Resolving Configuration Conflicts

 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 you install. If a hardware configuration error is detected, a 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 the system hardware and PCI interrupt requests. The program does not consider the requirements of the operating system or the application programs. See “Resolving Software Configuration Conflicts” for additional information.

message appears after the

Resolving Hardware Configuration Conflicts

Use the following information to help resolve hardware configuration conflicts:

1. Run the Configuration/Setup Utility program to view and change resources used by the system board functions. Record the current settings before making any changes. (See “The Configuration/Setup Utility” on page 21 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 the device needs. If the settings are incorrect or set to use a resource that cannot be shared, a conflict occurs and the device will remain deactivated by the configuration program.

4. Change system board jumpers or switches. See “Preparing to Install Options” on page 43 for instructions on removing the cover. 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 Adapters” on page 50.

Resolving Software Configuration Conflicts

The memory-address space and IRQs used by some hardware options might conflict with addresses defined for use through application programs or the expanded memory specification (EMS). (EMS is used only with DOS.)

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 a conflict exists.

To resolve conflicts, you can change the software or hardware configuration. Note: Start the Configuration/Setup Utility program to view the addresses used by

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

your system board functions.

If a device driver is causing a memory-address conflict, refer to your operating-system documentation or the documentation supplied with the device drivers.

Configuring the Ethernet Controller

Your Netfinity 5000 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 without software intervention. The controller supports half-duplex (HDX) and full-duplex (FDX) modes at both speeds.

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 5000 server in full-duplex mode.

auto-negotiation

Configuring the Ethernet Controller

. This auto-negotiation occurs

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 the ServerGuide CDs to install this device driver. Refer to the “ServerGuide and Netfinity Manager Information” section of this

Server Library

for instructions on installing device drivers. The ServerGuide CDs contain IBM Update Connector, a dial-up3 program that 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 (see “Related Publications” on page xii).

Attention:

 The 10BASE-T Ethernet and the 100BASE-TX Fast Ethernet cabling in the

network must be Category 5 or higher to meet various standards, including electromagnetic compatibility.

 You must install a device driver to enable your operating system to address the

Ethernet controller. Use the ServerGuide CDs to install this device driver. Refer to the information in the “ServerGuide and Netfinity Manager Information” section of this

Server Library

for instructions on installing device drivers, or for

more information about the ServerGuide CDs.

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

Response time will vary, depending on the number and nature of calls received.

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 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.

Notes:

1. For troubleshooting information, see “Troubleshooting the 10/100 Mbps Ethernet Controller” on page 149.

2. The Ethernet controller supports the operating systems that your server supports. To find out which operating systems your server supports, go to the following World Wide Web address:

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

If you need additional Ethernet connections, you can install an Ethernet adapter, such as an IBM 10/100 Ethernet adapter. Review your network-adapter documentation for any additional configuration requirements.

Note: If you are installing an IBM 10/100 Ethernet adapter, be sure to run the

Ethernet controller diagnostics and record the Ethernet controller configuration information before you install the adapter.

Failover for Redundant Ethernet

Your Netfinity 5000 server has an integrated Ethernet controller. The IBM Netfinity 10/100 Fault Tolerant Adapter is an optional redundant network interface card (NIC adapter) that you can install in your Netfinity 5000 server. If you install this NIC adapter and connect it to the same logical segment as the primary Ethernet controller, you can configure the server to support a configure either the integrated Ethernet controller or the NIC adapter 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 switching occurs without any user intervention. Applications with active sessions do not experience any data loss. When the primary link is restored to an operational state, the Ethernet traffic automatically switches back to the primary Ethernet controller.

Chapter 3. Configuring Your Server 33

Notes:

1. Only one controller in the redundant pair is active at any given time. For example, if the primary Ethernet controller is active, then the secondary Ethernet controller cannot be used for any other network operation.

2. Your operating system determines the maximum number of IBM Netfinity 10/100 Fault Tolerant Adapters that you can install in your Netfinity 5000 server. See the documentation that comes with the adapter for more information.

The failover feature currently is supported by OS/2, Windows NT, and IntraNetWare. The setup required for each operating system follows.

7. Select Close to exit from the Network setup. When you restart the server, the failover function will be in effect.

If a failover occurs, a message is written to the NT Event Viewer log. If the DMI instrumentation code for the integrated Ethernet controller is active (PCNET.EXE was run), a pop-up message is generated also.

Configuring Failover on IntraNetWare

1. Install the redundant NIC adapter according to the instructions provided with the adapter and in “Installing or Removing Adapters” on page 50.

2. Load the device driver by using the following command:

LOAD d:\path\PCNTNW.LAN PRIMARY=x SECONDARY=y

where d and

are the PCI slot numbers where the redundant pair is located.

The slot number associated with the integrated Ethernet controller can vary depending upon the configuration of the Netfinity 5000 server. To determine the slot number, load the driver with no parameters. The driver will display the available slot numbers. The slot number that is greater that 10000 will be the slot number of the integrated Ethernet controller. When the slot number of the integrated Ethernet controller is determined, reload the driver with the appropriate parameters.

3. When the driver is loaded, bind it to a protocol stack.

The failover function is now enabled. If a failover occurs:

Handling Static-Sensitive Devices

Static electricity, though harmless to you, can seriously damage server components or options.

Note: When you are adding an internal option, do not open the static-protective

package containing the option until you are instructed to do so.

When you handle options and other server components, take these precautions to avoid damage from static electricity:

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

you.

 Always handle components carefully. Handle adapters and memory modules

by the edges. Never touch any exposed circuitry.

 Prevent others from touching components.  When you are installing a new option, touch the static-protective package

containing the option to an unpainted metal surface on the server for at least two seconds. (This reduces static electricity from the package and from your body.)

Handling Static-Sensitive Devices

 When possible, remove the option and install it directly into the server without

setting the option down. When this is not possible, place the static-protective package that the option comes in on a smooth, level surface and place the option on it.

 Do not place the option on the server's covers or any metal surface.

Working with Adapters

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

Adapter Considerations

Your Netfinity 5000 server supports ISA and PCI adapters. You can install up to five adapters in the connectors on the system board.

The system board in your server contains 16-bit, ISA-bus expansion connectors and 32-bit, PCI-bus expansion connectors. Two of the expansion slots are shared PCI/ISA slots. The remaining slots support only PCI adapters. Your server supports only 5.0-volt adapters on the PCI bus.

Notes:

1. You can install PCI adapters in slots 1–5. Slots 1–4 are on PCI bus 1, slot 5 is on PCI bus 0. Both PCI buses are primary buses; when the system scans the buses to see what devices are on them, it scans PCI bus 0 first.

2. You can install ISA adapters in the shared slots 1 and 2. Note: If an ISA adapter is not a Plug and Play device, you must allocate the

system resources that the adapter will use. Use the Plug and Play choice in the Advanced Setup selection of the Configuration/Setup Utility program to allocate resources.

The following figure shows the location of the PCI and ISA expansion slot connectors on the system board.

in an expansion slot. The integrated

The integrated video controller is not removable. If you want to disable this controller and use a video adapter instead, you can install a video adapter in an expansion slot. When you install a video adapter, the server BIOS automatically disables the integrated video controller.

Attention: To avoid possible damage to adapters and server components, be sure that the adapters you install do not touch each other or the other components (such as the microprocessor) inside the server.

Installing or Removing Adapters

This section gives the procedure for installing an adapter. If you want to remove an adapter, reverse the following steps.

Working with Memory Modules

Adding system memory to your server is an easy way to make programs run faster. You can increase the amount of system memory by installing options called

memory modules

error correcting code (ECC) data protection.

Notes:

1. Your server comes with one or more dual-inline memory modules (DIMM)s installed.

2. The server supports 100 MHz, 64 MB, 128 MB, and 256 MB DIMMs.

3. Install only registered SDRAM ECC DIMMs.

4. When you are installing memory modules, you might find it more efficient to install them in adjacent connectors, with no vacant memory connectors in between. For example, if your server only has one DIMM installed in memory connector J15, install additional memory in the J16 memory connector; then, continue with connectors J17 and J22.

5. If you are installing DIMMs of different sizes, you might find it more efficient to install DIMMs with the greater memory capacity starting with connector J15. For example, when installing two 256 MB DIMMs, install the DIMMs in memory connectors J15 and J16.

. The server uses a noninterleaved memory configuration, with

Working with Memory Modules

6. After installing or removing a DIMM, you must save the new configuration information using the Configuration/Setup Utility program. See “Using the Configuration/Setup Utility” on page 22.

Table 1. Maximum Allowable Drive Sizes

Types of Cables

Drives connect to your server with cables. Each cable connector is designed to fit a corresponding connector on a drive.

Three types of internal cables connect to the drives in your server:

 A four-wire power cable connects to each drive.  A flat-ribbon signal cable connects to IDE devices.

– One flat-ribbon cable connects the internal diskette drive.

The connector on one end of this cable attaches to the system board. The primary diskette drive installed in your server (usually known as drive A) is attached to the connector on the other end of this cable.

Note: The primary diskette drive must always be attached to the drive

connector on the end of this cable.

– A second flat-ribbon cable connects the CD-ROM drive.

This cable has two drive connectors. A third connector attaches to the system board. The CD-ROM drive that comes with your server is attached to the connector on the end of this cable.

 Another cable connects internal SCSI devices. This SCSI cable has two

connectors that connect to SCSI devices:

– One to the backplane of the DASD hot-swap enclosure – One to a SCSI device you install in the open 5.25-inch bay

A third connector attaches to the SCSI connector on the system board.

External SCSI devices usually come with a SCSI cable. You attach one end of this SCSI cable to the SCSI connector on the back of the server, and the other end to the SCSI device. You usually can attach additional SCSI devices to this cable.

Chapter 4. Installing Options 57

SCSI Devices

Installing or Removing Internal Drives

Your Netfinity 5000 server supports drives that comply with American National Standards Institute (ANSI) SCSI Standards X3.131-1986 (SCSI), X3.131-1994, (SCSI-2), X3.277-1996 (SCSI-3 Fast-20 parallel interface), and X3.253-1995 (SCSI-3 parallel interface).

For a complete list of the SCSI devices supported on your Netfinity 5000 server, go to http://www.pc.ibm.com/support/ on the World Wide Web.

If you install additional SCSI devices, you must set a unique identification (ID) for each SCSI device. This enables the SCSI controller to identify the devices and ensure that different devices do not attempt to transfer data at the same time.

Note: Any information about SCSI drives also applies to other SCSI devices, such

as scanners and printers.

SCSI IDs

If you install SCSI devices, you must set a unique identification (ID) for each SCSI device that you connect to your server. This enables the SCSI controller to identify the devices and ensure that different devices do not attempt to transfer data at the same time.

The SCSI controller in your server supports SCSI IDs 0 to 15; ID 7 is reserved for the controller, ID 14 is reserved for the daughterboard (SAF-TE) on the DASD backplane. Use the SCSISelect Utility program to view the SCSI IDs of SCSI devices in your server. (See “Using the SCSISelect Utility Program” on page 35 for more information.)

Note: A daughterboard is a secondary adapter that can be plugged into another

adapter or the system board. The SAF-TE daughterboard on the DASD backplane makes available the status information about the DASD drives that meet the following conditions:

 The drives are part of a RAID environment  The status information comes from a supported IBM RAID adapter

If you install wide (16-bit) SCSI devices, you can set the IDs to any whole number between 0 and 6, or to any whole number between 8 and 13, or to 15. If you install narrow (8-bit) SCSI devices, you can set the IDs to any whole number between 0 and 6.

Your server automatically sets SCSI IDs for hot-swap hard disk drives, according to the jumper settings on the DASD backplane. Your server uses the hard disk drive SCSI IDs to send status information to the indicator lights on each hard disk drive. See “Status Indicators” on page 9 for the location and identification of the hard disk drive status lights.

Table 2 shows the default SCSI IDs that the backplane assigns for hot-swap hard disk drives.

Installing or Removing Internal Drives

You can change the default ID addresses of the drives by changing the jumper settings on the DASD backplane. See “SCSI Jumpers” on page 173.

Termination Requirements

The UltraSCSI controller and the backplane of the hot-swap bays provide termination for the internal SCSI bus (cable) in your server. There are no termination requirements for any SCSI devices you install in the hard disk drive bays or attach to this cable.

If you attach a SCSI cable and devices to the external SCSI connector, set the termination for the last device on that SCSI cable to Enabled. Refer to the instructions that come with the SCSI device for more information about termination.

Chapter 4. Installing Options 65

Installing Microprocessors

When you install an additional microprocessor, your Netfinity 5000 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 enhances performance for database and point-of-sale applications, integrated manufacturing solutions, and other applications.

Installing Microprocessor Upgrades

Your server comes with an Intel Pentium II microprocessor. This microprocessor incorporates MMX technology with built-in ECC level two (L2) cache. For the latest information about microprocessor upgrades available for your server, contact your IBM reseller, IBM marketing representative, or see http://www.pc.ibm.com/us/compat/ on the World Wide Web. If you do upgrade the microprocessor, use the instructions that come with the upgrade along with the instructions in “Installing or Replacing a Microprocessor” on page 67.

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 with the same internal and external clock speed, and the same cache size and voltage requirements as those of the currently installed microprocessor. Microprocessor internal and external clock frequencies and cache size must be identical.

Installing Microprocessors

 The voltage-regulator module (VRM) for the additional microprocessor plugs

into a connector on the system board (see “System Board Connectors” on page 169 for the location of the VRM connector). Because each microprocessor has specific power and voltage requirements, be sure to use the VRM that comes with the microprocessor.

Note: The voltage regulator function for the microprocessor that is shipped

with your server is built into the system board.

 If you select a setting for the frequency switch that is greater than the actual

frequency of the microprocessor, you might damage the microprocessor. The frequency switch settings are shown in Table 3 on page 70.

For additional information about microprocessor speeds, clock frequencies, and jumper settings, see Chapter 7, “Server Records and Specifications” on page 161.

70 Netfinity 5000 Server Hardware Information and Procedures

Installing or Replacing the Power Supply

Your Netfinity server is shipped with a 350-watt power supply that provides redundant power through the use of two internal power modules. If your server load does not exceed 175 watts, and a problem occurs with one of the power modules in the power supply, the other module takes over the load. For power loads above 175 watts, you can install a second, optional, power supply to provide redundant power for the server. The second power supply contains one 175-watt power module. With the optional second power supply installed, if a problem occurs with any of the power modules, the remaining two power modules supply the needed 350 watts of power.

The LEDs on the back of each power supply indicate the status of each of the power modules. If an LED is not on, there is a problem with the power supply module, and the power supply must be replaced.

 To install or remove the optional second power supply, see the instructions that

come with the option.

 To replace the 350-watt power supply, contact an IBM service technician to

have the system serviced.

If you want to install or remove any other options, do so now. Otherwise, go to “Completing the Installation” on page 76.

Chapter 4. Installing Options 71

Connecting External Options

The information in this section supplements the instructions that come with the external options (SCSI drives, printers, modems, and other serial and parallel devices). To connect external options, see the documentation that comes with the options.

Adding External SCSI Devices

Your server comes with a 16-bit UltraSCSI controller on the system board, which provides two independent SCSI channels. This controller has two 68-pin, shielded, high-density connectors: one internal, on the controller, and one external, on the back of the server. You can use these connectors to install an additional internal SCSI device in your server or to attach up to fifteen external SCSI devices to your server.

The internal SCSI connector provides support for SCSI devices installed inside the server. The external SCSI connector provides support for external SCSI devices.

Notes:

Connecting External Options

1. If you plan to install both internal and external SCSI devices, you must follow the instructions given in “Installing or Removing Internal Drives” on page 56 in addition to the instructions in this section. Read “Installing or Removing Internal Drives,” and then return here.

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

2. Do not exceed the following cable lengths:

 If you connect one or more Fast SCSI devices to the SCSI controller, the

total length of all cables (internal and external) must not exceed 3 meters (9.8 feet).

 If you do not connect Fast SCSI devices to the SCSI controller, the total

length of all cables must not exceed 6 meters (19.7 feet).

You must set a unique SCSI ID for each external SCSI device so that the controller can identify the devices. The controller can then ensure that different devices do not attempt to transfer data at the same time. Therefore, do not set the SCSI IDs for external devices to the values you used for the controller.

If you plan to attach an external SCSI device, you might need to order an additional SCSI cable. To use an external device with the Netfinity 5000 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. If a SCSI cable does not come with the external device, or if it is the wrong type, you will need to order one. To select and order the correct SCSI cable for use with the external device, contact your IBM reseller or IBM marketing representative.

Updating the Server Configuration

When you start your server for the first time after you add or remove an internal option or an external small computer systems interface (SCSI) device, you might see a message telling you the configuration has changed. You might need to install device drivers (required only if the option has a device driver). Refer to the documentation that comes with your option for information about installing any required device drivers.

Notes:

1. If you remove the last (terminated) SCSI device from the external SCSI cable connected to the SCSI connector on the back of the server, the server might not recognize any SCSI devices that are still connected on that SCSI channel (cable). See Chapter 6, “Solving Problems” for information on correcting this situation.

2. When a hard disk drive is added and you want to include it in your startup sequence, use the Start Options selection of the Configuration/Setup Utility programs (see “Start Options” on page 28).

3. When you install an ISA legacy adapter, you must allocate system resources to support it (see “Plug and Play” on page 30).

Serial Port Connectors

Serial ports are used to communicate with printers, plotters, external modems, auxiliary terminals, and other computers. Your server provides two serial ports (A and B), and a special type of serial port (Management Port C, described on the next page). You can add more serial ports by installing a serial adapter in one of the expansion slots.

Note: Serial port A can be shared by the system-management processor and

Server Library

Serial ports transfer data

asynchronously

; they can 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 115 200 bps. The bits-per-second measurement is commonly referred to as the

baud rate.

Each of the two serial connectors provided on your Netfinity 5000 server uses a 9-pin, D-shell connector.

Table 4 shows the pin-number assignments for the serial port connectors. The pin-number assignments conform to the industry standard.

Universal Serial Bus Ports

The universal serial bus (USB) is an emerging serial interface standard for telephony and multimedia devices. Each USB port is a single connector for devices that previously used serial, parallel, keyboard, mouse, and game ports. USB technology uses Plug and Play technology to determine which type of device has been attached to the connector. Each USB device is accessed by a unique USB address. A device called a hub is used to convert a single USB connector into multiple attachment points. A hub has multiple ports where peripherals can be attached. USB provides 12 megabits-per-second (Mbps) bandwidth with a maximum of 63 peripherals and a maximum signal distance of five meters (16 feet

4.9 inches) per segment. Note: If more than one USB device is to be attached, the devices must be

connected to a hub. Your Netfinity 5000 server does not support a keyboard attached to the system USB port.

Your Netfinity 5000 server comes with two USB ports. Table 9 shows the pin-number assignments for the USB port connectors.
