FCC ID: A09-89XWW

The FCC wants you to know...

This equipment has been tested and found to comply with the limits for a Class B
digital device, pursuant to Part 15 of the FCC rules. These limits are designed to
provide reasonable protection against harmful interference in a residential
installation.

Any changes or modifications made to this equipment may void the user's
authority to operate this equipment.

This equipment generates, uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that
interference will not occur in a particular installation. If this equipment does
cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the equipment and receiver

• Connect the equipment into an outlet on a circuit different from that to

which the receiver is connected

• Consult the dealer or an experienced radio/TV technician for help

The user may find the following booklet prepared by the Federal Communications
Commission helpful: How to Identify and Resolve Radio-TV Interference
Problems. This booklet is available from the U.S. Government Printing Office,
Washington, D.C., 20402. Stock No. 004-00398-5.

All external cables connecting to this basic unit need to be shielded. For cables
connecting to option boards, see the option manual or installation instructions.

This digital apparatus does not exceed the Class B limits for radio noise emissions
set out in the radio interference regulations of the Canadian Department of
Communications.

This equipment is in the 2nd Class category (information equipment to be used in
a residential area or an adjacent area thereto) and conforms to the standards set by
the Voluntary Control Council For Interference by Data Processing Equipment
and Electronic Office Machines aimed at preventing radio interference in such
residential area.

When used near a radio or TV receiver, it may become the cause of radio
interference.

Read the instructions for correct handling.
This equipment meets or exceeds requirements for safety in the U.S. (UL 1950),

Canada (CSA C22.2 No. 950), and Europe (EN 60950/IEC 950) with Nordic
requirements.

This equipment meets or exceeds the ergonomic requirements of ZH1/618 and is
certified to bear the GS mark by TUV Rheinland of Germany.

This equipment has been tested for radio frequency emissions and has been
verified to meet VDE 0871 Class B.

Audience

This guide is written specifically for anyone responsible for operating,
configuring, and expanding the Prioris HX MP Server family.

Organization

This guide contains the following:

• Chapter 1: Introduction—This chapter provides general information about

your server. For example: providing a comfortable working environment,
supplied diskettes and CD-ROM disk, and learning where to obtain help.

• Chapter 2: Configuring Your Server—This chapter explains how to

configure your server using the System Configuration Utility (SCU).

• Chapter 3: CD-ROM Disk and Startup/Utility Diskette —This chapter

describes how to access on-line help, server utilities, video, SCSI, and
mouse drivers from the "Getting Started" program contained on the CD­ROM disk.

Also, refer to the README files on the supplied diskettes and the system disks that
you made using the

"Getting Started"

program.

vii

listing mapping and address information related to server memory and
various main logic board devices (keyboard controller, interrupt controller,
Direct Memory Access (DMA) controller, etc.).

"Getting Started" Program

Your server comes with a "Getting Started" program on a CD-ROM disk. This
program enables you to access on-line help information on how to use your
server and specific information about its features. If you have Microsoft’s
Windows for Workgroups installed, you can access the "Getting Started"
program directly. If you have another operating system installed, or no
operating system installed, you must use the supplied Startup/Utility diskette to
access the "Getting Started" program on the CD-ROM disk. The "Getting
Started" program topics include:

About This Guide

• Registration/Welcome— Introduces the Prioris HX MP Server family,

and enables you to run the user registration program, if available (USA
only).

• Hardware —Provides access to your server’s help files. These files

provide the necessary information to help you operate and expand your
server. The Prioris HX MP System and Options Configuration Guide is
also available in this section.

• Server Utilities — Provides access to on-line help files that contain

information to help you configure your server using the SCU and other
server utilities.

• Troubleshooting — Provides access to troubleshooting information, a

Field Replaceable Unit (FRU) list, and error messages.

• Customer Support — Provides service information, hotline phone

numbers, bulletin board service, and warranty information.

• System Disks — Enable you to make master media diskettes for video,

mouse, and SCSI drivers.
