Preface

This guide shows yefi how to install, operate and maintain the RD54-D, -R fixed
disk drive subsystems. An RD54 fixed disk drive can store 159 Mbytes of
information.

You can use your free-standing RD54-D (desktop) or RD54-R (rackmount) subsys-

tems as an add-on to MicroPDP-11, MicroVAX, PDP-11/23 PLUS, and other Q-Bus
systems. You can easily connect these subsystems to an existing system or include
them in new designs.

HOW TO USE THIS GUIDE

This guide has four chapters and four appendices. They describe the following
topics.

Chapter 1 shows you how to install your RD54 subsystem, connect the subsystem
to a MicroPDP-11, MicroVAX, or MicroPDP-11 system, and how to format the
subsystem.

Chapter 2 describes the function of the RD54 front panel switches, buttons, and
indicator lights. Refer to your software documentation for information on how to
use the subsystem with your system.

These subsystems operate with an RQDX3 controller module installed in the host
computer. Chapter 3 describes the modules and cables you need to prepare the
MicroPDP-11, MicroVAX, and PDP-11/23 PLUS systems.
NOTE

Only qualified service personnel should install the necessary

boards and cables in the host computer. Refer to the RQDX3

Subsystems User’s Guide for more information.

Preface

Chapter 4 describes how to troubleshoot minor problems. This chapter also
includes removal and replacement procedures for RD54 subsystem parts.
NOTE

Only qualified field service personnel should make major repairs

or replace subsystem parts.

The appendxces list logical unit numbers, system specifications, and connector pin
numbersand signals. Appendix D describes service option available frem Digltal

FOR THE BEST RESULTS

Your RD54 fixed disk drive subsystem is a delicate precision instrument, and subject to damage if handled incorrectly. It will give you good, rehable service if you
observe the following precautions.

e Follow instructions carefully when installing your RD54 fixed disk drive

subsystem.

® Do not drop or bump the fixed disk drive. The maximum impact a fixed disk

installed in a desktop box can withstand is a drop of 15 cm (6 in) to a hard

surface.
e

Use care when you move your RD54 subsystem.

e Pack your fixed disk drivein its original packing material. This prevents damage

from shocks and vibrations when transporting or shipping your subsystem.

IF YOU NEED HELP

e Refer to Chapter 4, Troubleshooting.
e For hardware questions, call your service representative.

e For software questions, call your sales representative and ask for an access code
number for the Digital Phone Support Center (PSC).
