•	See the documentation provided with your operating system for information on configuring high resolution video drivers provided on the supplied CD-ROM.

•	Read any README files accompanying the video driver software on the CD-ROM.

•	Refer to the documentation supplied with any separate video adapter for more information on loading high resolution video drivers compatible with that video adapter.

NOTE
The video resolution of your monitor must be matched to the capabilities of the video controller installed in your server.  Refer to your monitor´s documentation for more information about your monitor and video adapter´s maximum display capabilities.

	CAUTION  Do not connect a low resolution monitor to a server that has been configured with high-resolution video drivers.  High resolution drivers can damage a 640 × 480 monitor.

video adapters

A video adapter is an expansion board which, when inserted into one of the expansion slots in your server, allows the computer to display information on the monitor. PRIORIS HX Servers are supplied with onboard video controller circuitry that enables you to display information on a monitor without installing a separate video adapter.  You can also install a separate video adapter in an appropriate expansion slot.


Disk Drives

The PRIORIS HX Server family uses a variety of disk drives to store and access information.  These servers may contain as many as eleven drives of various types, as follows:

•	the factory-installed CD-ROM drive

•	the factory-installed 3½-inch diskette drive

•	two 5¼-inch or 3½-inch devices in the upper left drive bays

•	seven hot-swappable SCSI storage devices (SBBs) in the hot-swap storage bay

NOTE
PRIORIS HX Servers do not support IDE-based hard disk drives.  Your server is designed specifically to use SCSI-compatible devices.

For specific information on individual types of disk drives and storage devices, click on the desired item in the following list.

CD-ROM Drives

Hard Disk Drives

RAID Controllers

Storage Building Blocks (SBBs)

Tape Backup Drives


CD-ROM Drives

A CD-ROM drive accesses information previously stored on compact disks.  CD-ROM disks can contain very large quantities of data, including audiovisual images, music, encyclopedic reference information, fonts and type faces, and so on.  You cannot, however, transfer information from another drive or your computer´s memory to a CD-ROM disk.

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

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

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.

Storage Building Blocks (SBBs)
Backing Up the Hard Disk


RAID Controllers

Your PRIORIS HX Server can be equipped with specialized hard disk controller technology that enables you to more effectively access and protect data using multiple hard drives.  This controller uses a Redundant Array of Inexpensive Disks (RAID) to access data faster, improve scalability and I/O performance, and increase the reliability of stored data.

RAID controllers accomplish this by storing data from a single file on more than one hard disk drive.  This enables the server to access data from the file more quickly, and (depending on the RAID level used) to recover data from a corrupted hard disk drive by taking a copy of the same data from a drive that has not been corrupted.

RAID levels supported by the optional RAID controller are as follows:

•	Level 0 (Striped Data)
This level enhances server performance by spreading data across multiple drives.  This increases your server’s data transfer rate because of a more balanced I/O load.

•	Level 1 (Disk Mirroring)
This level enhances data availability by mirroring data across more than one disk drive.  This increases server reliability because if one of the SBBs fails, data is still available on another SBB.

•	Level 5 (Striped Data/Striped Parity)
This level increases server performance by spreading data and error correction information across multiple drives.  This not only increases data throughput but also increases data availability.

Storage Building Blocks (SBBs)
Backing Up the Hard Disk


Storage Building Blocks (SBBs)

The seven-slot hot-swap drive bay in your server is specifically designed to contain Storage Building Blocks (SBBs).

SBB hard disk drives are "hot-swappable".  They can be inserted in or removed from the hot-swap drive bay while your server is operating, and retain the data stored on them even when they are not installed in your server.

See also:	LED Status Indicators (SBBs)


LED Status Indicators (SBBs)

There are two LED indicators on the front of each SBB hard disk drive.  These LEDs indicate whether the drive is in use and whether it is operating properly.

•	The left-hand LED (green) is the device activity LED, and is on or flashing when the SBB hard disk drive is active.

•	For RAID servers, the right-hand LED (amber) is the fault LED.  When it is on or flashing, an error condition exists.

	CAUTION If you remove an SBB hard disk drive from a non-RAID server while the left (green) LED is on or flashing, you might lose or damage the data on the drive.
Green -	Amber -
Left LED	Right LED 	Indication

On	Off	Device is operating properly

Flashing	Off	Device is operating properly

Off	Off	Device is inactive and operating normally.

On	On	Fault status; device is hung.  Replace SBB.

Off	On	Fault status; device is inactive and spun down.  Replace SBB.

On	Flashing	Fault status; device is inactive and spinning down due to a fault.

	CAUTION Do not remove an SBB hard disk drive while the right (amber) LED is flashing (device is spinning up or down), you might lose or damage the data on the drive.


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.

3.	Create the same directory on your hard disk drive and then copy the above files to it.

4.	Insert a blank formatted diskette into drive A.

5.	On drive A, make a directory for the files previously copied.

From drive C: type MAKECRD.  This copies the files to drive A.

6.	Remove the crisis recovery diskette from drive A and store it in a safe place.


Using the Crisis Recovery Diskette

The crisis recovery diskette must be used only if your server's BIOS fails or if a BIOS upgrade was unsuccessful.  If your server's BIOS fails:

1.	POST detects an error after a normal boot cycle or a BIOS upgrade.

2.	The BIOS in the bootblock memory executes.

3.	Your server beeps several times.

4.	The diskette drive begins searching for the crisis recovery diskette.

5.	Turn off power to the server and set the recovery jumper (J39) on the main logic board to recovery mode.

Refer to Main Logic Board Jumpers.  Observe all appropriate precautions when working with the main logic board.

6.	Insert the crisis recovery diskette into drive A and power on the computer.

7.	After the BIOS has been reloaded, remove the crisis recovery diskette from drive A and turn off the power.

8.	Set the recovery jumper (J39) to normal mode to prevent unauthorized personnel from loading a new server BIOS.

9.	Turn the power back on for normal operation.


Upgrading Your Server's BIOS

Perform the following steps to update your server's BIOS in the flash memory.

NOTE
You should create a Crisis Recovery Diskette before performing this procedure.  Refer to Creating a Crisis Recovery Diskette for instructions on how to do so.

1.	Turn on your server and allow the POST to complete.

If POST detects an error refer to POST & Boot Messages and take the appropriate steps to correct the problem.  After the problem has been resolved, restart the server.

2.	Insert the Startup and Utilities Diskette.

3.	At the MS-DOS prompt, enter the following commands:
cd a:\upgrade
PHLASH

A screen appears on your monitor warning you that you are about to erase your server's BIOS.

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]

4.	Press [Enter] if you want to continue.  If not, press [Esc] to cancel.

5.	Once you press [Enter], PHLASH.EXE automatically updates your server's BIOS.

6.	After the flashing process completes, your server automatically reboots itself so changes immediately take effect.

7.	Remove the Startup and Utilities Diskette.


QAPlus/FE

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

Adding Mass Storage Devices

Your server has three drive bay areas.  Mass storage devices such as SCSI hard disk drives, floppy diskette drives, SCSI CD-ROM drives, and SCSI tape backup systems are installed in these drive bay areas.  The three drive bay areas are:

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

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


Connecting SCSI Devices

Your server supports up to 10 internal SCSI devices.  Additional SCSI devices can be added to your server by using an EISA- or PCI-based SCSI host adapter installed in an available expansion slot in conjunction with an external SCSI expansion box.

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.  See the relevant topic below  for information on single or dual SCSI channel configurations.

Your server has been supplied with a standard wide (68-pin) SCSI cable that attaches to the SCSI host adapter at one end and to SCSI bus A at the other end.  The three middle device connectors support the upper left and right drive bays.  Three wide-to-narrow cable adapters were provided to connect narrow devices in the upper drive bay areas.  A SCSI bus jumper connects SCSI bus A and SCSI bus B.  A wide internal terminator is installed at the end of SCSI bus B.

Additional cables are available to support multiple SCSI channels or external SCSI devices.  Contact your Digital sales representative for ordering information on SCSI cables and devices.

SCSI Drive IDs

SCSI bus device addresses are automatically assigned in the hot-swap drive bay depending on the slot number in which they are installed.  The address jumper on the storage backplane is used to override the default addresses.  The default settings are listed in the following table and can be set manually to different addresses at your option.  The storage backplane can be configured as two separate SCSI buses or as a single SCSI bus using a jumper cable.  Note that:

•	The SCSI ID addressing is independent of the single or dual SCSI bus arrangement.  Make sure you select unique SCSI IDs for all SCSI devices on the SCSI bus.

•	You must use a wide SCSI host adapter to set SCSI IDs greater than seven.

•	Your CD-ROM drive and tape IDs must be set manually.  Refer to your manufacturer's documentation for information on setting drive IDs.

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.

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 SCSI devices in the storage system cabinet.

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

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

•	Use only a high-density external connector.


Installing a Device into the Top-Right Drive Bay

Expansion Brackets


Expansion Brackets

You can install 3½-inch half-height devices in the top-right drive bay.  If you plan on installing a 3½-inch device in a 5½-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.


Installing or Replacing a Device Into the Hot-Swap Drive Bay

Hot-swapping allows you to remove or install an SBB while the server remains online 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).

NOTE
Not all SCSI host adapters support the hot-swap method.  Refer to your SCSI host adapter documentation to determine if the hot-swap method is supported.  Also, you might need to reconfigure the server to recognize the devices you installed.

Use the following procedure to install or replace an SBB:

1.	Unlock and open door.

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

3.	Insert 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.

See also:	System Configuration Utility (SCU)


SCSI Configuration Guidelines

Your PRIORIS HX Server has a hot-swap backplane that supports one or two channel SCSI host adapters and up to seven 3½-inch SBBs.  You can also use multiple SCSI host adapters to improve server performance or to increase the number of SCSI devices that you connect to your server.

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

•	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.

NOTE
Your server uses a single-ended actively terminated cable.  Use only the SCSI cable supplied with your server.

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. Use SCSI ID 0 through 6 (narrow devices) and 0 through15 (wide devices) for the remaining SCSI devices.

See also:	SCSI Drive IDs

•	Your server is supplied with a wide (68-pin) five connector cable assembly.  A wide-to-narrow cable adapter is used to connect narrow (50-pin) devices for SCSI operation.  Three cable adapters, two 68-pin internal terminators, and one 68-pin-to-68-pin jumper cable are supplied with the standard wide SCSI cable.

•	SCSI device drivers are required to operate your SCSI devices.  Refer to Configuring Your Server for creating and loading your SCSI device drivers.  Also refer to your SCSI host adapter documentation.

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


Using Multiple or Multi-Channel 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.


Installing Additional Server Memory

Adding more memory allows your server to run larger, more complicated software and run it more quickly.

Your server will support up to 512 MB of parity memory and 256 MB of ECC memory using SIMM sockets 0 through 7.

Your server comes with at least 16 MB of memory.  When adding additional memory make sure you:

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

•	Fill two sockets at a time using the same SIMM size, type, and speed
(4 MB, 8 MB, 16 MB, 32 MB, and 64 MB densities are available for parity memory.  16 MB and 32 MB densities are available for ECC memory.).

•	Fill sockets 0 and 1 before sockets 2 and 3, sockets 0 through 3 before sockets 4 and 5, and sockets 0 through 5 before sockets 6 and 7.

POST and Boot Messages

The POST displays messages to alert you to errors in hardware, software, and firmware or to provide operating information about your server.

Each time the POST displays a message on your screen, the server's speaker beeps twice.  If an error occurs before the monitor is initialized, specific beep codes sound to alert you to a problem.  The following table lists a general grouping of system messages.  In addition, each message is accompanied by text describing the message and in most cases, a recommended solution to the problem.

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

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 error 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

Main Logic Board Jumpers

Jumper pins allow you to set specific server parameters. They are set by changing the pin location of jumper blocks.  A jumper block is a small plastic-encased conductor (shorting plug) that slips over the pins.  To change a jumper setting, remove the jumper from its current location with your fingers.  Place the jumper over the two pins designated for the desired setting.  Press the jumper evenly onto the pins.  Be careful not to bend the pins.

Entries in blue in the following table represent the factory default settings.

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.


Windows
