Installing Options

If you have options (such as adapters, diskette drives, hard-disk drives, or memory-module kits) to install, go to Chapter 4, “Installing and Removing Options” to install them. After you complete option installation and have updated your configuration, return to this chapter to connect the cables and complete the server installation.

Connecting the Cables

This section provides information on how to connect the various cables your server may require, depending on your options.

1. If you are using a keyboard and display:  Attach the keyboard cable to the keyboard connector and the display to the

display connector on the back of the display adapter in one of the expansion slots.

 If you are installing a mouse or other pointing device, connect that cable.  Connect the display power cord to the display.

If you are using an ASCII terminal:

 Connect the ASCII terminal cable to the S1 port on the server.  Connect the ASCII terminal power cord to the ASCII terminal.

2. Attach adapter cables to any adapters installed in the expansion slots. For more

instructions on adapter cabling, please refer to the documentation that came with your adapter, or to the

Systems

3. Make sure all externally attached devices are turned off.

4. Connect the server power cord to the power connector on the server. Secure

the connection; then plug the display power cord and the server power cord into properly grounded electrical outlets.

Attention: As soon as the server power cord is plugged into the server and power outlet, the power is on within the server not plug in the server power cord if the cover of the server is removed.

whether or not the server is turned on.

Finishing the Installation

Your server hardware is set up, and you are ready to learn about your system and make backup copies of important software. The order in which you do these tasks is up to you. Use the following checklist as a guide:

Ø Record your identification numbers

Your server has important identification information that you might need if you have it serviced.

Appendix A, “System Records” shows where to find these numbers, and provides space to record and retain this information.

Ø Install the operating system

If AIX is preinstalled in your server, or if you plan to install AIX yourself, refer to the AIX documentation for instructions.

Ø Install application programs

To install application programs, follow the instructions supplied with each application program.

Chapter 1. System Startup 1-9

1-10 7046 Model B50 User's Guide

Chapter 2. Using the Server

This section provides information on how to start and use the server.

Starting the Server

Perform the following steps to start the server.

1. Turn on all attached devices.

2. Turn on the server.

3. If power does not come on when you turn on the server, ensure that the power cord, located at the back of the server, is plugged in. If this does not solve the problem, go to Chapter 8, “Determining Hardware Problems.”

When you turn on the server, the Power LED comes on and the server starts a POST (power-on self test). During this test, the disk status LED flashes intermittently. The server beeps a short beep, and progress indicators appear on the operator panel display (if a display is attached).

 Copyright IBM Corp. 1999 2-1

Console Selection

After the server starts up, you can select the system console for your server if one has not been chosen before (or if your display adapter configuration has changed). The system console functions as the primary display and keyboard for your server.

On a graphical display, the console selection screen looks like the following illustration:

If the console selection screen appears, each display and ASCII terminal attached to your server appears with a number. To define a display or ASCII terminal as your system console, press the number on the keyboard that corresponds to the system console you choose.

If a console is not chosen after a certain amount of time, the server automatically chooses an ASCII terminal as the system console (whether or not one is installed). To choose another system console, you must shut down and restart the server.

2-2 7046 Model B50 User's Guide

POST Indicators

If you are using an ASCII terminal (attached to serial port 1), a series of POST indicators appear on the screen as each subsystem is initialized.

If you are using a directly attached keyboard and a graphical display attached to a display adapter, then the POST progress indicators appear as icons across the bottom of the display as follows:

Memory Modules: Tests system memory.

Keyboard: Initializes the keyboard and mouse. When this

icon appears, you can choose one of several different startup options.

 Pressing the F1 key or the numerical 1 key activates the

System Management Services.

 Pressing the F5 key or the numerical 5 key invokes the

default boot list mode, located in firmware.

 Pressing the F6 key or the numerical 6 key works like the

F5 key or numerical 5 key except firmware looks for a boot record according to the custom bootlist that was setup by System Management Services.

 Pressing the F8 key or the numerical 8 key selects the

Open Firmware Command line.

If any of these keys are pressed, the chosen option occurs after all of the POST icons appear. If no keys are pressed, the server boots from the default boot list and starts the operating system after all POST icons appear.

Network: Initializes network adapters.

SCSI: Initializes SCSI Adapters.

Chapter 2. Using the Server 2-3

Audio: Initializes the audio system. For the audio system to take effect, any startup option key must be pressed before the end of audio initialization.

If the POST process stops and indicates an error on the LED or console in any one of these subsystems, record the error number and refer to Chapter 8, “Determining Hardware Problems.”

For more information on:

 The System Management Services (started by pressing F1 or the numerical 1

key), see Chapter 3, “Using System Management Services.”

 The Open Firmware command line (started by pressing F8 or the numerical 8

key), see Chapter 3, “Using System Management Services.”

 Alternate boot modes (started by pressing F5 or the numerical 5 key, or F6 the

numerical 6 key), see “Working with System Startup Options.”

The last indicator to appear is the boot indicator. This indicator shows that the server hardware is preparing to load and start the operating system.

At this point, the server prompts you for the power-on password if it has been set. (See Chapter 3, “Using System Management Services,” for instructions on setting passwords.)

If three incorrect responses are given to the password prompt, the server locks up and must be turned off and turned on again to be reset. If the power-on password has been lost, then the power-on password jumper must be reset or disabled:

 To reset the power-on password, remove the server power cable; then remove

the server battery for 30 seconds. See “Changing the Battery” on page 4-36 for the location of the battery.

 To disable the power-on password, see “Enabling and Disabling the Power-On

Password” on page 4-8.

Attention: Removing the battery may also erase system configuration information stored in the nonvolatile random access memory (NVRAM), such as the custom boot list.

Note: If the privileged-access password has been lost, contact your authorized

reseller or marketing representative.

2-4 7046 Model B50 User's Guide

If no bootable operating system image is found on any of the storage devices listed in the system firmware boot list, then the server attempts to boot again. With each attempt, you have the opportunity to start the System Management Services (SMS) as described in Chapter 3, “Using System Management Services.”

Stopping the Server

Attention: When you use the shutdown procedure for your server, enter the correct

shutdown command for your operating system before you stop the server. Failure to do so may result in the loss of data. If you need information on the shutdown procedure for your operating system, see the operating system documentation.

1. Before stopping the programs and operating system, notify your system administrator and users that the server is going to be shut down.

2. After you shut down the operating system, turn off the server.

3. Set the power switches of the attached devices to Off.

Using the Power Switch and Indicator

The power switch and indicators on the front of your server allow you to control power to the server, observe server power status, and observe disk activity.

These features also have other built-in capabilities to assist you in diagnosing system problems and observing server status:

 When the server is turned on by pressing the power switch, the power LED lights

steadily.

 The disk drive LED lights whenever the hard disk drives within the server are

being used.

 If AIX is installed and running, a memory dump of system information can be

requested.

– To enable this function, the sysdumpdev -K command must be executed

before an error condition exists.

– To request the memory dump, press the reset button on the operator panel.

Requesting a memory dump directs AIX to save system information to a predefined file before turning off the system. This feature can be used to assist in recovery from system problems.

– When a memory dump has been requested, the power LED blinks quickly

(about 10 flashes per second) to indicate that the dump has been started. This blinking ceases after about a minute whether or not the dump is

Chapter 2. Using the Server 2-5

complete, and the LED returns to its steady, lit state until the system turns off or reboots when the dump is complete.

– The memory dump file can be viewed by entering the AIX command

sysdumpdev -L

Using the Operator Panel and Reset Switch

The operator panel on the front of the server contains a four-digit display and reset button. The four-digit display is used by your server to display progress indicators during system startup, and can also display error messages.

The function of the reset button depends on the operating system installed in the server. Consult your operating system documentation for a description of its function.

Working with System Startup Options

If no keys are pressed after the server power is turned on, the server searches a list of devices (the then the server loads and starts the operating system. This is called a

default boot list

) for a bootable image. If a bootable image is found,

2-8 7046 Model B50 User's Guide

Working with Standalone versus Online Diagnostics

When the server attempts to boot in service mode (from either the default or custom boot list) and locates a diagnostics CD-ROM before any other bootable image, then the server starts standalone diagnostics.

Standalone diagnostics can be used on servers installed with any supported operating system.

When the server attempts to boot in service mode (from either the default or custom boot list) and first locates a bootable image on disk drive or network connection, then the server starts online diagnostics.

Online diagnostics can be used only on servers installed with the AIX operating system.

Because the type of diagnostics started (standalone or online) depends on the source from which they are loaded, changing the boot list used during system startup can affect which diagnostics are run.

Recommended Boot Options

The procedures under “Loading Diagnostics in Service Mode Boot” on page 2-7 produce the following recommended results:

 Default boot list (F5 or 5 key) with diagnostics CD-ROM inserted loads

Standalone Diagnostics.

 Custom boot list (F6 or 6 key) without diagnostics CD-ROM inserted loads Online

Diagnostics, if AIX is installed on a device in the custom boot list.

The keyboard is divided into four sections: 1 - Function keys are multipurpose keys and their function is controlled by the

operating system. 2 - Typewriter keys are similar to a standard typewriter. Their function is controlled by

the software. 3 - Control keys move the cursor on the screen and do programmed control

functions. The movement and functions depend upon the application used. 4 - The Numeric keypad is arranged like a calculator to help when typing numbers.

Chapter 2. Using the Server 2-11

On all of the keyboards, you can adjust the tilt position for typing comfort. To tilt the keyboard, pull out on the keyboard legs. The legs snap into position. To decrease the tilt of the keyboard, rotate the keyboard legs until they snap into the bottom of the keyboard case.

The keyboard cable plugs into the connector at the rear of the server.

Using the Mouse

The mouse is a hand-operated locating device. Consult your application documentation for the exact use of the three-button mouse.

You can use the mouse to perform functions such as positioning a cursor, selecting items from a menu, or moving around in your document much easier and faster than if you used only the keyboard. The cursor moves exactly as you move the mouse on a flat surface, such as a desktop.

When you move the mouse around on a flat surface, the cursor moves on the display screen; the movement changes the position of the cursor.

2-12 7046 Model B50 User's Guide

With the mouse buttons, you can perform functions such as selecting and deselecting options, extending your selection, or choosing a command. The precise function of your mouse depends on the software you are using.

The mouse has a cable that plugs into a connector at the rear of the server.

Handling the Mouse Correctly

For best operation, handle the mouse with care. Incorrect handling can damage the mouse.

Do not:

 Operate the mouse on cloth, unfinished wood, newspaper, or carpet.  Drop or hit the mouse.  Carry the mouse by holding onto the cable.  Expose the mouse to extreme temperatures or direct sunlight.  Place the mouse in liquid spills.

Caring for the Mouse

The operating surface for the mouse should be smooth, clean, and flat. For example, you can operate the mouse on the following surfaces:

 Finished wood  Glass  Enamel  Plastic

 Paper (except newspaper)

 Metal Rough surfaces collect contaminants that can be transferred to the interior of the

mouse by the ball. Rough surfaces can also cause the pads located on the bottom of the mouse to prematurely wear. A deeply pitted surface could cause erratic operation of the mouse. The surface you use should be free from spills, dirt, dust, lint, wax, eraser dust, and other foreign matter.

To care for the mouse:

 Inspect the work surface for spills or other contaminants.  Dust the work surface.  If you are using a paper pad, inspect it for wear and replace it if necessary.

Chapter 2. Using the Server 2-13

Cleaning the Mouse

Using the 3.5-Inch Diskette Drive

The following section provides information on 3.5-inch diskette drive.

Diskette Compatibility

The server has a 1.44MB diskette drive installed. The 1.44MB diskette drive can format, read, and write diskettes compatible with the

following diskette drives:

 1.0MB diskettes with 720KB formatted data capacity  2.0MB diskettes with 1.44MB formatted data capacity (HD).

Format the diskette according to its specified capacity.

Write-Protecting 3.5-Inch Diskettes

Write-protecting diskettes is necessary so that important information is not accidentally lost. When diskettes are write-protected, you can read information from the diskettes, but you cannot write information on them.

There is a write-protect tab on the 3.5-inch diskette. To locate the write-protect tab, turn the diskette over with the label facing down.

 To prevent writing onto a diskette, slide the write-protect tab to open the protect

slot.

Password

When you select this icon, the following screen is displayed.

Power-On Password

Setting a power-on password helps protect information stored in your server. If a power-on password is set for your server, the Power-On status icon is shown in the locked position. If a power-on password is not set, then the Power-On status icon is shown in the unlocked position (as shown in the screen above).

When you select the Entry icon, a screen with eight empty boxes displays. Type your password in these boxes. You can use any combination of up to eight characters (A–Z, a–z, and 0–9) for your password. As you type a character, a key appears in the box.

Chapter 3. Using System Management Services 3-11

Press Enter when you are finished; you must type the password again for verification.

If you type the password incorrectly, press Esc and start again. After you have entered and verified the password, the power-on password status

icon flashes and changes to the locked position to indicate that the power-on password is installed.

If you previously had set a power-on password and want to remove it, select the

Remove icon.

Notes:

1. If you want to disable an installed power-on password (but not erase it), move the power-on password jumper as described in the section beginning on page 4-8. Moving the jumper back to the default position re-enables the power-on password, unless it has been removed in the System Management Services Utilities or by removing the battery.

must

be disconnected before removing the battery.

Remote Mode: The remote mode, when enabled, allows the system to start from the defined boot device. This mode is ideal for network servers and other servers that operate unattended. You

must

set a power-on password before you can enable the remote mode. When the remote mode is set, the icon label changes to Remote <On>.

If you remove the power-on password, the remote mode is automatically reset, and the icon label returns to Remote <Off>.

Note: To use the remote mode feature for booting unattended devices, you must

enable the automatic power-up feature. See “Enabling Automatic Power-Up” on page 4-13 for instructions on enabling the automatic power-up feature, which allows the server to turn on whenever AC power is applied to the server (instead of having the server wait for the power button to be pushed).

Privileged-Access Password

The privileged-access password protects against the unauthorized starting of the system programs. To set the privileged-access password, you must first change a jumper on the system board. See Chapter 4, “Installing and Removing Options” on page 4-1 to locate and change the password-enabling jumper, then return here.

If the password-enabling jumper has been changed, select the Entry icon to set and verify the privileged-access password.

Chapter 3. Using System Management Services 3-13

Press Enter when you are finished; you must type the password again for verification.

If you type the password incorrectly, press the Esc key and start again. Note: If an error occurs when you attempt to set the privileged-access password,

then make sure the password-enabling jumper has been changed. (See Chapter 4, “Installing and Removing Options” on page 4-1 for instructions on changing the password-enabling jumper.)

After you have entered and verified the password, the privileged-access password icon flashes and changes to the locked position to indicate that your server now requires the password you just entered before running system programs.

Attention:

1. Once the password-enabling jumper has been changed and the privileged-access password has been set, great care must be taken to preserve the privileged-access password.

If you set the privileged-access password and

later misplace it, your server must be returned for service.

To prevent loss of system use, record the privileged-access password immediately whenever it is changed.

2. If no user-defined boot-list exists, and the privileged-access password has been enabled, you are asked for the privileged-access password at startup every time you boot your server.

Moving the password-enabling jumper back to the default position does or erase the privileged-access password. Removing the jumper or moving the jumper back to the default position only prohibits changing or disabling this password with the System Management Services.

Chapter 4. Installing and Removing Options

Adding hardware options to your server increases its capabilities. Many options are available (see “Available Options” below). This chapter can help you decide which options to add to your server, and shows you how to install them. When adding an option, use these instructions along with those that came with the option.

If you have installed (or removed) options previously, you might be able to perform some activities without detailed instructions. These activities are listed in the “Before you begin” boxes of the procedures.

Before you install or remove an option, be sure you are familiar with the safety procedures and component-handling guidelines described in “Safety Considerations” on page 4-2. These precautions and guidelines help you work safely with your server or options.

Available Options

The following are some of the options available for your server. Check with your authorized reseller or marketing representative for the latest information.

 Peripheral Component Interconnection (PCI) adapters  Additional system memory in the form of memory modules  Cabling an Ultra SCSI adapter

 Internal drives  Microprocessor upgrades

 Enable or disable the power-on password  Enable or disable the privileged-access password  Enable or disable automatic power-up  Enable or disable the external SCSI connector

Safety Considerations

Observe the following safety precautions anytime you work with the server.

DANGER

An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

Before installing or removing signal cables, ensure that the power cables for the system unit and all attached devices are unplugged.

When adding or removing any additional devices to or from the system, ensure that the power cables for those devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you add a device.

Use one hand, when possible, to connect or disconnect signal cables to prevent a possible shock from touching two surfaces with different electrical potentials.

During an electrical storm, do not connect cables for display stations, printers, telephones, or station protectors for communication lines.

CAUTION: This product is equipped with a three–wire power cable and plug for the user's safety. Use this power cable with a properly grounded electrical outlet to avoid electrical shock.

DANGER

To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the server.

4-2 7046 Model B50 User's Guide

Handling Static Sensitive Devices

Attention: Static electricity can damage this device and your system unit. To avoid

damage, keep this device in its static protective bag until you are ready to install it. To reduce the possibility of electrostatic discharge, follow the precautions listed below.

Electrostatic Discharge Protection

To prevent electrostatic discharge:

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

you.

 Handle the device carefully, holding it by its edges or its frame.  Do not touch solder joints, pins, or exposed printed circuitry.  Do not leave the device where others can handle and possibly damage the

device.

 While the device is still in its anti-static package, touch it to an unpainted metal

part of the system unit for at least two seconds. (This drains static electricity from the package and from your body.)

 Remove the device from its package and install it directly into your system unit

without setting it down. If it is necessary to set the device down, place it on its static-protective package. (If your device is an adapter, place it component side up.) Do not place the device on your system unit cover or on a metal table.

 Take additional care when handling devices during cold weather as heating

reduces indoor humidity and increases static electricity.

Tools Required

To install or remove options from your server, you need a flat-blade screwdriver. Any additional tools needed depend upon the specific option and are noted in the instructions that come with the option.

Chapter 4. Installing and Removing Options 4-3

Removing the Cover
