Inserting CD-ROM Disks
Removing CD-ROM Disks


Handling CD-ROM Disks

Observe the following precautions when handling CD-ROM disks:

•	Always handle the disk by its edges, as shown in the illustration.

•	Do not place heavy objects on any CD-ROM disk.

•	Store disks in a temperature range between 10 °C and 51 °C (50 °F and 125 °F).


Inserting CD-ROM Disks

	Hold the disk by its edges and place it (label side up) into the fully open disk caddy, making sure that it is properly seated.  (See the documentation accompanying your CD-ROM drive for information on opening, closing, and operating the drive.)


Removing CD-ROM Disks

To remove a disk from a CD-ROM drive, open the disk caddy and lift the disk straight up and out of the drive.  (See the documentation accompanying your CD-ROM drive for information on opening, closing, and operating the drive.)


Hard Disk Drives

Hard disk drives are the most commonly used devices for storing and retrieving large quantities of information.  Most computers, including your server, use a hard disk drive as their primary data storage device.  Hard disk drives vary widely in physical size and storage capacity.

After a typical hard disk drive is installed in a computer, it is usually not removed unless it becomes damaged or defective, or unless it is being replaced with another hard disk drive.  Certain types of hard disk drives, however, are designed to be easily removable, so that the data they contain can either be stored in a safe location or quickly transferred to another computer.  Your server is designed to use both typical and removable hard disk drives.

See also:	Backing Up the Hard Disk


Backing Up the Hard Disk

It is very important that you periodically back up the information stored on your server's hard disk.  If you experience problems with the hard disk, you might be unable to retrieve the information stored on the hard disk unless you have made backup copies of that information.

There are several ways to make backup copies of information stored on your hard disk.  For example:

•	To back up a few files, use your operating system's file copying commands.

•	To back up many files or directories at once, use backup software designed for or supplied with your operating system.

•	To back up the drivers supplied with your server, use the System Disks option in the Getting Started program.

•	To maintain the integrity of information in a network environment, use your server's disk-mirroring and hot-swappable hard disk features to store multiple copies of your data on separate hard disks.

•	Various software manufacturers offer specially designed application software to assist in backing up hard drives.  See your software vendor for further information.

Refer to the supplied operating system documentation for more information on your operating system's backup and file copying capabilities.


tape back-up drives
Tape backup drives

A tape backup drive is an optional accessory which stores information on high-capacity magnetic tapes.  Tape drives can store large quantities of information more rapidly than floppy diskette drives, and are therefore especially useful for backing up information from hard disk drives.


CD ROM Caution
CD-ROM Caution

Be sure to exit any application which might access the CD-ROM drive before removing a CD-ROM disk.


Monitor Note

System Configuration Utility (SCU)

This group of Help topics provides detailed information on how to configure your server when relocating, adding, or removing EISA/ISA/PCI expansion boards and how to change your server’s factory-defined BIOS Setup options.

Your server was pre-configured at the factory using the System Configuration Utility (SCU).  This means that your server’s hardware (CPU, memory, cache, mass storage devices, expansion boards, etc.) has been identified and configured for optimum performance.  If you need to make changes to this configuration, Digital recommends that you use the SCU along with the information provided in this help file.

SCU and Setup Options


BIOS Setup Options

Digital recommends that you use the SCU (instead of the BIOS Setup utility) if you need to change any of the setup options listed at the end of this chapter.  You can access these options using Step 3: View and Edit Details from the Configure Computer menu.

As an added feature, the SCU creates and stores all setup changes in a System Configuration (.SCI) file.  Afterwards, this SCI file can be used on any Prioris HX MP Server that is equally configured and can serve as a backup to the EISA configuration stored in NVRAM memory.  The SCI file is maintained on the System Configuration Utility diskette and has a default name of SYSTEM.SCI.


SCU Diskette(s)

Five separate language-specific SCU diskettes come with your server.  These diskettes contain the SCU utility and the files necessary to configure expansion boards.


When to Run the SCU

Always run the SCU each time you add, remove, or relocate PCI, ISA and EISA expansion cards so no two boards use the same server resources (IRQs, I/O address, memory address, etc.).

For ISA expansion boards, run the SCU before adding, removing, or relocating.  Running the SCU first can identify and resolve resource conflicts, as well as indicate the proper switch settings to configure ISA expansion boards.

For PCI or EISA expansion boards, run the SCU after adding, removing, or relocating.  In this case, the SCU will automatically assign the proper server resources to the PCI or EISA expansion boards so they will operate correctly.

Configuring_Expansion_Boards
Configuring Expansion Boards

Each time you add, remove, or relocate any EISA/ISA/PCI expansion board, you need to run the SCU to identify their operating characteristics, server resource requirements, and slot locations.  Based on this information, the SCU will then automatically assign the proper server resources to EISA expansion boards and inform you as to what jumper or switch settings need to be manually set on ISA expansion boards to avoid resource conflicts.

The SCU identifies an expansion board’s operating characteristics and resource requirements is through Configuration (.CFG) files.  These files contain main logic board, EISA, PCI, and ISA expansion board vital characteristics and the server resources they require for proper operation.  If you installed additional EISA, PCI, or ISA expansion boards, make sure you copy the CFG files (and overlays, if applicable) supplied with the expansion boards, to the System Configuration Utility diskette before attempting to configure your server.

If a configuration file is not available for a specific ISA expansion board, use the supplied generic ISA expansion board configuration file.  Note that this file will only supply basic ISA information and will not identify potential resource conflicts or the correct jumper and switch settings.  You must use the documentation that came with your ISA expansion board to properly configure it for use in your server.

If you are unfamiliar with utility programs and their uses, carefully read and understand these Help topics before attempting to use the server utilities.  Also, make sure your server operates as expected following the instructions in Initial Server Setup.


PHLASH.EXE

All servers have BIOS software in a Read-Only, non-volatile memory (ROM) chip.  This BIOS initializes hardware and boots the operating system when the server is turned on.  The BIOS also provides access to other services such as keyboard and disk drives.

Your server comes equipped with flash memory.  This means that you can restore your server's BIOS simply by running the PHLASH.EXE utility.  You can also upgrade your server's BIOS to future releases by running PHLASH.EXE along with any flash BIOS update diskette if necessary.

Only use PHLASH.EXE to upgrade your server’s BIOS if you are instructed to do so by an authorized Digital support representative.  PHLASH.EXE and BIOS updates are available on the Digital Bulletin Board (BBS).


QAPlus/FE

Your server comes with QAPlus/FE diagnostic software on a separate diskette.  Refer to the QAPlus/FE documentation for instructions on installing and using the QAPlus/FE software.


Flash Note

If you need to flash a different file other than the one on your diskette, copy the new file to the upgrade directory and type:

PHLASH [filename]


EPP3SMC

EPP3SMC.EXE is a device driver for configuring your parallel port as an enhanced parallel port (EPP).  Before loading this device driver, check the documentation for the device you want to connect to the parallel port and make sure it supports EPP mode.  If it does not, you do not need to load this device driver.  If the device does support EPP mode, you should:

1.	Copy EPP3SMC.EXE from the Startup/Utility diskette to your hard disk drive.

2.	Edit your CONFIG.SYS file to enter the path for EPP3SMC.EXE.

Refer to your DOS documentation for information on editing your CONFIG.SYS file.  For example a line in your CONFIG.SYS might be:

Installing Additional Server Memory

Adding more memory allows your server to run larger, more complicated software and run it quicker.  Your Prioris HX MP server will support up to 512 MB of standard parity memory on a single memory module, or up to 1 GB on two memory modules.  This memory can either be installed entirely on one memory module or can be split between two memory modules.

Each memory module contains two sets of memory banks (banks 0 through 3).  Each bank consists of four SIMM sockets.  Your server comes with at least 32 MB of memory installed in bank 0.  When adding additional memory make sure you:

•	Install 36-bit SIMMs having an access time of 70 ns or less.

•	For single memory module configurations, fill one bank (four sockets) at a time using the same SIMM size, type, and speed (8 MB, 16 MB, and 32 MB densities are available).

•	Fill bank 0 (0H and 0L) before bank 1 (1H and 1L), bank 1 before bank 2 (2H and 2L), bank 2 before bank 3 (3H and 3L).

•	For dual memory module configurations, fill one bank (four sockets) at a time on each module using the same SIMM size, type, and speed (8 MB, 16 MB, and 32 MB).  For optimal memory performance, use the same number, size, type, and speed of SIMMs on each memory module.

Refer to Memory Configurations, Single and/or Memory Configurations, Dual for a list of SIMM combinations supported by your Prioris HX MP Server family computer and to Installing a SIMM  for detailed instructions on installing SIMMs.

•	Left-front access drive bay area (A)— This area has one 5¼-inch SCSI CD-ROM drive and one 3½-inch diskette drive (standard on all Prioris HX MP Servers).

•	Top-right front access drive bay area (B)—This area has room for two wide (68-pin) or narrow (50-pin) 5¼-inch or 3½-inch half-height SCSI devices or one full-height, 5¼-inch device.

•	Lower-right front access drive bay area (C)—This area has room for seven 3½-inch, wide or narrow Fast SCSI-2  hot swap devices.

See also:	Replacing Hot Swap Devices


SCSI Configuration Guidelines

Your server configuration, SCSI adapter(s), and all SCSI devices must work together for optimum performance.  When installing SCSI devices, use the following guidelines:

•	The last physical SCSI device on each end of the SCSI bus must be terminated.  Only use SCSI devices without terminators.  If your SCSI device came with a built-in terminator installed, you must remove or disable the terminator from the device before you complete the installation.

Refer to your SCSI device’s manufacturer documentation for the terminator location.

•	Each SCSI device (including the SCSI host adapter) must be configured with a unique ID number.  SCSI host adapters usually default to ID 7.  The SCSI CD-ROM drive defaults to ID 6.  Use the remaining IDs 0 through 5 (narrow and wide adapters) and 8 through 15 (wide adapters only) to configure hard disk drives and other SCSI devices.  Hard disk drives should be configured to start with SCSI ID 0 and the lower ID numbers.

Refer to SCSI Drive IDs.

Your server is supplied with the following cables:

•	One wide (68-pin) five connector cable assembly.  This cable assembly includes:

−	One wide 68-pin connector to connect to the SCSI host adapter.

−	Three wide-to-narrow adapters to connect the narrow (50-pin) CD-ROM drive and the two 5.25" bay devices for SCSI operation.

−	One wide (68-pin) connector to connect the SCSI host adapter to Channel A of the hot-swap backplane (if required).  A cable terminator is supplied if this connector is not used to connect to Channel A.

•	One 68-pin-to-68-pin jumper cable to connect the two hot-swap backplane segments together to make a single SCSI channel.

•	Two 68-pin internal terminators (one for channel A and one for channel B).

•	Two additional wide cables with two 68-pin unshielded connectors are supplied to connect to Channel A and Channel B on the hot-swap backplane.

Refer to the System and Options Configuration Guide for ordering and configuration information on additional SCSI cables and devices.

•	SCSI device drivers are required to operate your SCSI devices.  Your SCSI device drivers are located on the CD-ROM disk.  You can copy the SCSI device drivers to diskettes from the ”System Disks” section of ”Getting Started”.  Also, refer to the  Adaptec 7800 Family Manager’s Set or the EZ-SCSI documentation.


Expansion Brackets

	You can install 3½-inch half-height devices in the top-right drive bay.  If you plan to install a 3½-inch device in a 5¼-inch drive bay slot, you must first install expansion brackets onto the device.  Expansion brackets are either supplied with the device or can be purchased from Digital.  Contact your local Digital sales representative for additional information.


Top-Right Drive Bay

To install a device into one of the top-right drive bay slots, perform the following:

1.	Turn off your server.

2.	Disconnect external devices, ac power, and monitor power.

3.	Unlock and remove side panels.

4.	Unlock and open door.

5.	Remove both plastic filler panels by pushing it out from inside server.

6.	Remove the bottom bracket from the left side of drive bay and attach it to device.

7.	Remove divider bracket from right side of drive bay (if installing a full-height device).

8.	Insert the device into the drive bay slot from the front.

9.	Secure the device to slot using supplied mounting screws.

Refer to Connecting Devices.


Replacing Hot Swap Devices

Hot-swapping allows you to remove or install an SBB while the server remains on-line and active eliminating interference with the server’s operation.  For SBBs, you can use the hot-swap method to replace a device providing that the device is not active (green activity LED is off).

Use the following procedure to install or replace an SBB:

1.	Unlock and open the right side door.

2.	Remove filler panel or SBB by pressing the two tabs together to pull filler panel or SBB out.

3.	Insert new SBB into the guide slots and push it in until it is fully seated and the mounting tabs engage the shelf.

4.	Close and lock door.

Refer to:	Connecting Devices
SBB Status


SBB LED Status Indicators

The hot-swap backplane monitors shelf status to identify error conditions or failures.  This status is displayed on the SBB LEDs.  The left LED displays the device activity status, and the right LED displays the fault status.

•	The left LED (green) is the device activity status LED and is on or flashing when the SBB is active.

•	For RAID servers, the right LED (amber) is the SBB fault LED and indicates an error condition when it is either on or flashing.

SBB Status LEDs

Activity Status LED	Fault Status LED	Indication
On	Off	Device is operating properly
Flashing	Off	Device is operating properly
Off	Off	Device is inactive and operating normally.  There is no fault.
On	On	Fault status, device is hung.  Replace SBB.

Connecting Devices

The Prioris HX MP connects to the following types of devices;

SCSI Devices

External Storage Box

To connect any device, perform the following:

1.	Connect the data cable to the device.

Be sure the cable is connected with the correct orientation.  Most cables and sockets are keyed so that you cannot connect them backwards.  If your cable or drive are not keyed, you must connect pin 1 of the cable to pin 1 of the socket.

Pin 1 of the cable is on the edge with the colored stripe.  Pin 1 of the socket should be marked number "1" at one end of the socket or with a number "1" printed on the circuit board near one end of the socket.

2.	Connect a power cable to the device.  Use one of the 4-pin connectors from the power supply.

3.	If necessary, secure the device with two screws on each side.  Use the screws that came with the device.

4.	If the device is an internal device that has no front panel and is installed in the upper drive bay area, replace the plastic filler panel.

5.	Replace and lock both side panels.

6.	Connect the power cord and monitor cord to the back of the server.  Connect any external devices and plug the power cord into the wall outlet.

7.	Run the SCU to reconfigure your server.


Storage Backplane

Your storage backplane supports seven hot-swap devices split between two SCSI bus sections.  SCSI bus A and SCSI bus B.  SCSI bus A is the upper section and consists of four SCSI device connections.  SCSI bus B is the lower bus section and consists of three SCSI device connections.  These buses can be configured as two independent SCSI channels or as one channel by installing a wide SCSI jumper cable.

Your server has been supplied with three SCSI cables and three SCSI bus terminators to configure your server for up to three internal SCSI channels.  Additional cables are available to support external SCSI devices or as replacement cables.

External Storage Box
SCSI External Storage Box

You can use the SCSI connector at the rear of your server to connect an external SCSI storage box.

To connect an external SCSI storage box, follow these instructions:

1.	Connect the external device making sure the SCSI bus is properly terminated.

2.	Run the SCU and any other SCSI utilities to configure your server.

See also:	External SCSI Bus Guidelines


External SCSI Bus Guidelines

•	Make sure that the SCSI addresses you select for the external SCSI devices do not conflict with other devices in the server.

•	Make sure that the external SCSI bus is terminated properly.

•	For proper operation, the total length of the SCSI cable must not exceed 1 meter (3.28 ft).

•	Use only a high-density external connector.


SCSI Host Adapters

The following guidelines apply if you configure your server using multiple or multi-channel SCSI host adapters.

•	The SCSI host adapter with the lowest BIOS address is identified by the server as the “primary” SCSI host adapter.  If you are loading the operating system from a SCSI hard disk drive, this primary or boot drive must be connected to the primary SCSI host adapter.  The SCSI address of the primary SCSI hard disk drive must be set to the lowest SCSI address connected to the SCSI host adapter.

•	To improve server performance, you might want to  distribute the SCSI devices across the SCSI host adapters.  When arranging SCSI devices, make sure each device connected to a SCSI host adapter is assigned a unique SCSI address.

•	Each operating system has different limitations regarding the number of SCSI host adapters that are supported.  Refer to your operating system documentation for additional information.

•	SCSI IDs on one channel do not interfere with the IDs on another channel.  This applies when installing two SCSI host adapters that implement a different bus as well as dual channels on a single SCSI host adapter.


External SCSI Bus

You can use additional SCSI cables and/or host adapters to connect external SCSI devices to your server.  Consult your Digital sales representative for information on SCSI options and cables.

To connect the storage backplane to an external SCSI bus:

1.	Remove the terminator from the storage backplane for the bus you want to connect.

2.	Connect the 68-pin unshielded cable connector to the storage backplane (A).

3.	Using a screwdriver, gently pry away one of the SCSI knockouts at the rear panel .

4.	Screw the 68-pin or 50-pin external shielded connector to the rear panel (B).

5.	Connect the external SCSI device making sure the external device is properly terminated.

Beep Codes

When POST finds an error and cannot display a message, the server's speaker emits a series of beeps to indicate the error and places a value in I/O port 80h.  During POST, if the video configuration fails or if an external ROM module fails a checksum test, then your server beeps three times (one long beep, and two short beeps).

The following table lists other fatal errors and their associated beep codes.  Each code represents the number of short beeps that are grouped together.  Fatal errors (errors that lock up your server) are generally the result of a failed main logic board or some other add-on component (SIMM, BIOS, server battery, etc.).  If you cannot resolve problems using the troubleshooting procedures in the appropriate Troubleshooting sub-topic, have a Digital service representative examine your server and repair or replace any defective components.

Beep Code	Error
2-2-3	BIOS ROM checksum
3-1-1	Test DRAM refresh
3-1-3	Test keyboard controller
3-4-1	Test 512K base address lines
3-4-3	Test 512K base memory
2-1-2-3	Check ROM copyright notice
2-2-3-1	Test for unexpected interrupts


Post Message Note

Italics indicate variable parts of a message such as memory addresses, hexadecimal values, and so on.  These messages can differ at each occurrence.


Trouble Caution

Some failed server components should be replaced only by an authorized Digital service representative.  Users who replace these server components might affect their warranty and/or service coverage


Initial Trouble Note

If you need to return a failed component, pack it in its original container and return it to Digital for service.

If you are a self-maintenance customer, call your Digital service representative for assistance and recommendations.

See also:	Abbreviations


application

A program or set of programs that operate in conjunction with an operating system, also called “application software”.  Categories of application software include word processors, databases, spreadsheets, and telecommunications software.  Specific examples of application software include WordPerfect, Lotus 1-2-3, and Procomm Plus.


AUTOEXEC.BAT

A special-purpose batch file.  Each time you turn on or reboot your server, MS-DOS searches for the AUTOEXEC.BAT file and executes the commands in that file.  (If MS-DOS cannot find an AUTOEXEC.BAT file, the server might not boot properly or operate correctly.)


base memory

Memory accessible to MS-DOS, up to a maximum of 640KB; also called “conventional memory”.  See also expanded memory (EMS) and extended memory (XMS).


Basic Input/Output System

Abbreviated as BIOS.  The BIOS enables your server to control major input/output devices such as the keyboard and disk drives.


batch file

A defined series of commands saved in a file, which can then be executed as a unit in order to save time and/or keystrokes.  (MS-DOS batch files have the extension .BAT.  Batch files created for other operating systems, such as Windows, might have other extensions.)


bit

The smallest unit of electronically stored information, represented by the binary digits 0 or 1.  (See also byte.)


bits per second

Abbreviated as bps.  The number of binary digits transmitted by an electronic device (such as a modem) in one second.  Also see bit.


board

A device containing electronic circuitry and microprocessors.  Usually used in connection with a modifying word, as follows:
main logic board	The primary electronic component of your server.
expansion board	A board which enhances your server’s abilities in some way
video board	A board which enables your server to display information on a monitor


booting

A process of self-testing and server configuration.  A “hard boot” occurs each time your server is turned on.  A “soft boot” or “reboot” occurs when you press the Reset button or the [Ctrl]-[Alt]-[Del] key combination.  The boot process might include a memory test, loading of device drivers via CONFIG.SYS, and execution of the AUTOEXEC.BAT file.


byte

The amount of storage space used to represent one character (such as a letter or number).  One byte contains eight bits.  The following table describes other commonly-used units of electronic storage space.  These units are typically used to describe amounts of available memory.

KB	Kilobyte	1,024 bytes
MB	Megabyte	1,048,576 bytes
GB	Gigabyte	1,073,741,824 bytes


cache memory

A block of reserved memory that improves server performance by minimizing the number of CPU memory accesses.  The server achieves this by storing recently used data or instructions in reserved memory, where it can be retrieved more quickly.


central processing unit

Abbreviated as CPU.  A computer chip; specifically, the microprocessor that forms the heart of your server.  Examples include Intel’s i486 and Pentium CPUs.


channel

The path along which information travels between your server and a SCSI device.  Channels are established based on the manner in which SCSI devices are connected to the server and to each other.  Several SCSI devices installed in the same server can be configured either in a single channel or multiple channels, depending on the capabilities of the host adapter or adapters used to control them.


CMOS

A type of memory that uses very little power.  CMOS memory is often used to store information such as the time and date for your server’s internal clock.


command line

The basic prompt presented by an operating system such as MS-DOS (for example, C:\>), from which you can execute operating system commands or run application software.  An alternative to a graphical user interface.


CONFIG.SYS

MS-DOS uses the CONFIG.SYS file to help configure your server to correctly operate the specific hardware and software installed in your system.  Each time you turn on or reboot your server, MS-DOS uses the CONFIG.SYS file to identify and load device drivers needed to operate specific hardware and software.


controller

Electronic circuitry which directs the operation of particular devices or components installed in or connected to your server.  The circuitry may take the form of a dedicated board (for example, a video adapter or RAID controller) or be incorporated into the main logic board (for example, onboard video circuitry).


cursor

A line, block, or other indicator on your monitor screen.  The cursor identifies the point at which typed characters or other information will appear on the screen.  (Note that while a mouse or other pointing device can often be used to move the cursor, the mouse-pointer and a normal cursor might appear in different places on your screen.)


data striping

The practice of spreading the contents of data files across multiple hard disk drives, so that parts of a single file may reside on different drives.  A strategy used by RAID controllers to allow information to be accessed more quickly and reliably.  Data striping may be used independently or in combination with disk mirroring.


device driver

A file that gives your server specific information on operating a particular physical device (such as a CD-ROM drive or a mouse) or application software (such as a memory manager).  Device drivers are usually loaded into memory each time your server boots if they are listed in your CONFIG.SYS file.)


Direct Memory Access

Abbreviated as DMA.  A method of transferring data between stored memory (such as a hard disk) and an input/output device (such as a printer port) that bypasses the CPU.


disk mirroring

The practice of storing identical information on multiple hard disk drives, so that the contents of one drive "mirror" those of another.  A strategy used by RAID controllers to increase the security of information stored in a given server.  Disk mirroring may be used independently or in combination with data striping.


expanded memory (EMS)

Memory beyond 640KB that can only be accessed by use of expanded memory manager software.  Expanded memory can be provided by installing an expanded memory expansion board, or by using software that enables extended memory to simulate expanded memory.  Some application software requires expanded memory in order to operate correctly.


extended memory (XMS)

Memory beyond 1MB that can only be accessed by use of extended memory manager software (such as HIMEM.SYS, included with MS-DOS).  Some application software, including Windows and Windows-based software, requires extended memory in order to operate correctly.  Extended memory can be added to your server, within specified limits, by installing SIMMs.


firmware

Information that is permanently stored in your server’s ROM and cannot be changed.  This might consist of application software and/or configuration information about certain aspects of the server.  Your server’s BIOS (see Basic Input/Output System) is an example of firmware.


graphical user interface

Abbreviated as GUI.  The visual “desktop” image generated by software such as Windows, that allows you to operate your server by using a mouse or other pointing device to manipulate icons that might represent application software, files containing data, and/or operating system commands.  An alternative to a command line.


hardware

Computers, printers, modems and other physical devices for managing electronically stored information.


hot-swapping

The ability to remove and replace hard disk drives or other electronic devices installed in your server while the server is powered up and operating.  Hot-swapping typically requires the use of specialized hardware, such as Storage Building Blocks.


icon

A symbol or picture on your monitor screen that represents a file, a software application, an operating system command, or some other form of stored information.  Some software applications make use of “button bars” or “toolbars”; these features consist of a number of icons grouped together.


infra-red (IR)

A form of light energy that can be used to broadcast information without the use of wires.  (Television remote control units typically use infra-red beams.)  With the proper specialized devices, circuitry, and/or software, an infra-red beam can be used to transfer data files from one electronic device to another (for example, from a notebook computer to a desktop computer, or from a pocket-sized electronic organizer to a computer).


mapping

The process of identifying specific addresses and locations within your server’s memory, and describing what kinds of information might be found at those locations.  Sometimes referred to as device mapping or memory mapping.


media

Physical objects or devices used for storing information.  These might include floppy disks, hard disk drives, CD-ROM disks, and PCMCIA cards.


memory

The electronic space in which information can be stored and/or processed.  Types of memory include Random Access Memory (RAM), Read-Only Memory (ROM), expanded memory (EMS) and extended memory (XMS).


microprocessor

A computer chip that processes electronic information and instructions, such as Intel’s i486 or Pentium computer chips.  (Note, however, that not all microprocessors are central processing units.)


modem

A device for transmitting electronic information from one computer to another at high speeds over telephone lines.


multimedia

A form of electronic information that combines pictures, sounds, and text in an integrated manner. CD-ROM hardware and software is usually required to make use of information stored in the form of multimedia.


network

An operating environment, established by specialized hardware and software, which allows multiple computers to share resources.  These resources might include software, peripheral devices, or stored information.  Many types of networks require a dedicated server to operate correctly.


onboard video

Video controller circuitry that is incorporated into a computer's main logic board, so that you do not need a separate video adapter to display information on a monitor.


operating system

The software that tells your server how to manage and process electronically stored information, enables it to run application software, and controls the flow of information between various parts of your computer system.  MS-DOS, OS/2, and UNIX are operating systems.


Power-On Self Test

Abbreviated as POST.  A series of diagnostic tests performed by your server every time it is turned on (but not necessarily every time it is booted).


Random Access Memory (RAM)

Abbreviated as RAM; also called read/write memory.  The memory your server uses to manage information and software while that information and software is in use.  Information stored only in RAM is lost when your server is turned off.


Read-Only Memory (ROM)

Abbreviated as ROM.  Information or software stored in ROM is permanent, cannot be altered, and remains intact when your server is turned off.  (Note that you cannot move or copy information into ROM from other areas of your server’s memory.  In some cases, however, you can copy information from ROM into other areas of your server’s memory.)


Redundant Array of Inexpensive Disks (RAID)

A hard disk drive technology which allows your server to access information more quickly or store it more securely by using multiple hard disks.  Modes of RAID operation can include disk mirroring and data striping.  A set of multiple hard disks controlled by RAID technology is referred to as a RAID array.


ROM BIOS

See Basic Input/Output System and Read-Only Memory.  ROM BIOS software enables your server to control major input/output devices such as the keyboard and disk drives.


SCSI device

Hardware that communicates with your server via a specific data-transmission technology (Small Computer System Interface).  Devices that use the SCSI interface include CD-ROM drives and some hard disk drives. Internal SCSI devices can be installed in your server's drive bays, while external SCSI devices can be connected to your server using optional cables.


SCSI drive ID

An address assigned for each SCSI device installed in your server.  Some IDs might be set automatically, while others must be set manually when the relevant SCSI device is installed.  In order to avoid conflicts between SCSI devices, each such device installed in your server must have a unique address.  The same drive ID can only be assigned to two different SCSI devices if they are configured on different channels.


SCSI host adapter

A controller, usually in the form of an expansion board, which manages the flow of information between SCSI devices and your server.  The number of SCSI devices a host adapter can control varies depending on the controller circuitry it contains.


server

A computer in a network which is responsible for managing and allocating shared resources to individual computers in the network.  For example, a network server might contain application software or hard disk space for storing shared information.


SIMM

A Single In-line Memory Module. SIMMs are small memory boards that can be used to increase the amount of random access memory (RAM) in your server.  See your User’s Guide for more specific information about using SIMMs in your server.


software

A program or set of programs that operate in conjunction with an operating system, also called “application software”.  Categories of application software include word processors, databases, spreadsheets, and telecommunications software.  Specific examples of application software include WordPerfect, Lotus 1-2-3, and Procomm Plus.


storage backplane

The physical interface between hot-swappable Storage Building Blocks and a SCSI host adapter. SBB hard disk drives inserted into your server's hot-swap drive bays are physically connected to the storage backplane, which is connected by appropriate cables to the server's SCSI host adapter(s).


Storage Building Block (SBB)

A hard disk drive specifically designed to be capable of hot-swapping.  Often used in conjunction with a RAID array.


system utilities

Software designed to increase your server’s efficiency, determine whether it is operating properly, and/or correct problems that might arise as you use your server.  Some system utility software might be provided with your server (such as a Setup program).  Other utility software is available from various commercial and non-commercial sources.  Examples of utility software include Stacker, PKZip, and PC Tools.


video adapter

Also called a video controller or video board.  A board that enables your server to display information on a monitor screen.


video controller

Also called a video adapter or video board.  A board that enables your server to display information on a monitor screen.
