Safety

Handling static-sensitive devices

Attention: Static electricity can damage electronic devices and your system. To

avoid damage, keep static-sensitive devices in their static-protective package until you are ready to install them.

To reduce the possibility of electrostatic discharge, observe the following precautions:

 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 static-protective 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 because

heating reduces indoor humidity and increases static electricity.

Power supplies

Your server comes with three hot-swap power supplies. The power supplies can provide up to 550 watts each at 110 V ac input power, and 750 watts each at 220 V ac input power.

DANGER

Overloading an electrical circuit breaker is potentially a fire hazard and a shock hazard under certain conditions. To avoid these hazards, adhere to the instructions in the following statements.

1. If you are connecting to a 100–127 V ac power source,

connect each power cord to a separate branch circuit.

2. If you are connecting to a 200–240 V ac power source and

the branch circuit breaker rating is:

a. 13 amps or less, connect each power cord to a separate

branch circuit.

b. 14 amps to 19 amps, do not connect more than two

power cords to the same branch circuit.

c. 20 amps or greater, you may connect up to three power

cords to the same branch circuit.

In addition to the power supplies, your server comes with three 220 V ac power cords, and three 110 V ac power cords (U.S. only). Be sure to select the appropriate power cord voltage for your server environment. All three power cords must have the same voltage.

If you connect all three power cords of the same voltage to the power supplies, the three power supplies support redundancy and hot-swap capability.

For servers with redundant power, the loss of a single power supply will not affect the server operation. Replace a power supply that has failed as soon as convenient to help maintain the redundant power and cooling capability. When a power supply has failed and the Power Good light is on, the dc power LED on the power supply is off. See “Power supply LEDs” on page 156 for more information on the dc power LEDs. See “Replacing a hot-swap power supply” on page 84 for complete details on the power supplies.

Chapter 2. 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.

Viewing Distance

Lower Back Support

Seat Height

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.

 Copyright IBM Corp. 2001 17

Air circulation

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 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.

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. In a rack enclosure, be sure to maintain a minimum clearance of 203.2 mm (8 in.) between the rear of the chassis and the surface of the rear door when the door is closed.

Note: To accommodate the xSeries 370 server, a Rack Extension Option can be

installed on the IBM rack enclosure.

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 cords

directly into electrical outlets.

 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 15.

Chapter 3. Configuring your server

This chapter provides information on the Configuration/Setup Utility program that comes with your server. In addition, this chapter provides information on the SCSISelect Utility program.

The Configuration/Setup Utility program is part of the basic input/output system (BIOS) that comes with your server. Using these programs, you can set the system date and time, define input and output device parameters, and define system security.

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

Accessing server programs

After you start the server, several prompts appear on the IBM logo screen.

 To access the Configuration/Setup Utility program, press F1 when the prompt

Press F1 for Configuration/Setup appears. See “The Configuration/Setup

Utility program” on page 20 and “Using the Configuration/Setup Utility main menu” on page 21 for additional information.

 To access the Diagnostic Utility program, press F2 when the prompt Press F2

for Diagnostics appears. For information on running the diagnostics

programs, see “Diagnostic programs” on page 119.

 To access the utility programs in the System Partition, press Alt+F1 when the

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 configuration. The steps required to configure your server depend on the number and types of devices and programs that you install.

Your server supports PCI adapters and SCSI devices. Because of this flexibility, you can choose from among many adapters and devices.

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.

 Copyright IBM Corp. 2001 19

Your server comes with the following hardware configuration programs:

 Configuration/Setup Utility

With the built-in Configuration/Setup Utility program, you can configure I/O functions, such as serial and parallel port assignments; change interrupt request (IRQ) settings; and change the startup sequence for drives that you install. You also can use this 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 attach to the SCSI controller. 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 to 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 jumpers or switches on server components.

See “Changing jumper settings” on page 111 and “I/O function card jumpers” on page 104.

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 37.

5. Install software programs.

See the installation instructions that come with the software.

6. Resolve configuration conflicts.

See “Resolving configuration conflicts” on page 32.

The 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 (for example, defining diskette types, and so on).

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

Always run the Configuration/Setup Utility program if you add, remove, or relocate any hardware option, or if you receive an error message instructing you to do so.

20 xSeries 370 User's Reference

Review this chapter and the information that comes with the option before making changes. Also, record the current settings before making any changes.

Attention: Maintaining a record of your configuration information is especially important if you need to move the Clear CMOS register contents jumper, which erases all configuration information (see “I/O function card jumpers” on page 104 for details).

To start the Configuration/Setup Utility program:

1. Ensure that there is no diskette in the diskette drive. If the diskette drive contains a diskette, remove it.

2. Turn on the server and watch for the IBM logo screen.

If the server is turned on already, shut down your operating system and restart the server.

3. After you start the server, several prompts appear on the IBM logo screen. When the prompt Press F1 for Configuration/Setup appears, press F1.

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

Note: If you enter the power-on password and an administrator

(supervisor-level) password is also set, a limited version of the menu appears. To see the full menu, you must restart the server and enter the administrator password when you are prompted to enter a password. See “System security” on page 24 for additional information.

Configuring options

Before installing a new device or program, read the documentation that comes with it. Reading the instructions helps you to determine the steps that are required for installation and configuration. The following list provides a preview of the actions that might be required to configure your server.

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

See “The Configuration/Setup Utility program” on page 20.

2. Set jumpers or switches on the server components.

See “Changing jumper settings” on page 111 and “I/O function card jumpers” on page 104.

Chapter 3. Configuring your server 31

3. Set jumpers or switches on the device.

See the instructions that come with the adapter.

4. Install the adapter in the server.

See “Working with adapters” on page 68.

5. Install software programs.

See the installation instructions that come with the software.

6. Resolve configuration conflicts.

See “Resolving configuration conflicts.”

Resolving configuration conflicts

The resources used by your server consist of interrupt requests, direct memory access (DMA), I/O ports 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 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 configuration error 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 the system hardware and PCI IRQs. The program does not consider the requirements of the operating system or the application programs. See “Resolving software configuration conflicts” on page 33 for additional information.

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 functions and the installed options. Record the current settings before making any changes. (See “The Configuration/Setup Utility program” on page 20 for instructions.)

2. Determine which adapter or device is causing the conflict. (See Chapter 6, “Solving problems” for instructions.)

3. Change adapter jumpers or switches. Some devices use jumpers and switches to define the system resources that the devices need. 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.

32 xSeries 370 User's Reference

4. Change system jumpers or switches. See “Changing jumper settings” on page 111.

5. Remove the device or adapter. Some configurations are not supported. If you must remove an adapter, see “Working with adapters” on page 68.

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

your server functions. (See “The Configuration/Setup Utility program” on page 20 for instructions.)

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.

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

Using the SCSISelect Utility program

Note: If your server has a redundant array of independent disks (RAID) adapter

installed, use the configuration method that comes with the RAID adapter to view or change SCSI settings for attached devices.

Your server comes with a menu-driven configuration utility, called SCSISelect, that allows you to view and change SCSI settings.

Chapter 4. Installing options

This chapter provides instructions to help you add options to your server. Some option-removal instructions are provided, in case you need to remove one option to install another.

Before you begin

Before you install any optional hardware in your server, thoroughly review the information in this section. Also, review the power supply requirements described in “Replacing a hot-swap power supply” on page 84.

 Become familiar with the safety and handling guidelines specified under “Safety

information” on page 39 through “Handling static-sensitive devices” on page 43 and “Working inside a server with power on” on page 44.

 If you upgrade your server by installing a RAID adapter, you must configure

your disk arrays after you install hard disk drives, as described in “Installing internal drives” on page 79. Follow the instructions in the RAID adapter documentation after installing the drives. Then, return here to install your remaining options, if applicable. See Chapter 3, “Configuring your server” on page 19 for additional details about configuration and for a description of your server utility programs.

 You do not need to turn off the server to install or replace hot-swap power

supplies, hot-swap fans, hot-swap drives, or hot-plug PCI adapters.

– Hot-swap means that you can install or remove certain components, such

as power supplies, fans, and hard disk drives, without turning off the server, provided that your server contains hardware and an operating system that support the installation or removal of these components. These components are known as hot-swappable components, and more commonly referred to as hot-swap components.

– Hot-plug means that you can install or remove certain components without

turning off the server, after you perform an intervening action, provided that your server contains hardware and an operating system that support the installation or removal of these components. For example, before you can install or remove hot-plug PCI adapters, you must enable or disable the hot-plug PCI slots that contain or will contain these adapters. To do this, you must perform your operating-system-defined procedures for enabling or disabling the affected hot-plug PCI slots. Failure to do so might cause your system to lock up. Refer to your operating-system documentation for additional information. Hot-plug components are also known as hot-pluggable components.

 The orange color on components and labels in your server indicates hot-swap

or hot-plug components. This means that you can install or remove the component while the system is running, provided that your system is configured to support this function. For complete details about installing or removing a hot-swap or hot-plug component, see the information provided in this chapter.

 The blue color on components or labels indicates touch points where a

component can be gripped, a latch moved, and so on.
