Preface
Audience This guide is intended for all users of the DEC 3000 Model 800
/800S/900 AXP system. It describes how to install and remove
internal options.
Purpose of This
Guide This guide provides the following information for internal
options:
• How to install
• How to test for successful installation
• Drive SCSI ID settings
Structure of
This Guide This guide is organized as follows:
Designation Contents
Chapter 1 Overview of options, including a list of internal
options and their locations in the system unit.
Chapter 2 What you need to do to prepare your system for
adding one or more options, including shutting
down software, checking system configurations,
shutting down hardware, and removing panels.
Chapter 3 Information on installing a CD, tape or diskette
drive in the system unit.
Chapter 4 Information on installing a fixed disk drive in
the system unit.
vii

Designation Contents
Chapter 5 Information on memory modules, including
how to determine which modules you need,
installing them in and removing them from the
system unit.
Chapter 6 Information on TURBOchannel options,
including an overview of TURBOchannel and
the system unit option positions and installing
and removing them from the system unit.
Chapter 7 What you need to do to replace panels and
confirm that options were installed correctly
inside your system unit.
Index
Two Ways To
Add Options There are two ways to add options inside the system unit: add
the options yourself or have a Digital service representative add
them.
If you choose to add the options, note that system preparation
takes about 20 minutes, additions take about 10 to 15 minutes
per option, and system restoration takes about 10 minutes, on
the average.
What You
Should Know
Beforehand
The instructions in this guide assume you are prepared to open
the system unit, disconnect and connect internal cables, and use
antistatic precautions. You should be familiar with concepts such
as SCSI addresses, and the following diagnostic test displays:
– System power-up messages
– Configuration displays resulting from the show config , show
memory
, and show device console commands
For more information on these diagnostic test displays, refer to
the DEC 3000 Model 800/800S/900 AXP Owner’s Guide. For
more information on SCSI concepts, refer to Small Computer
System Interface: An Overview.
CAUTION:
Option Damage Improper addition of a drive or module could lead to damage and
failure of that drive or module, or to damage of the system. The
system warranty may not cover such a failure.
viii

Conventions in
This Guide The following conventions are used in this guide:
show config Words in this format indicate commands
that you must enter exactly as shown. For
example: Use the show config command.
WARNING: Warnings contain information to prevent
personal injury. Read these carefully.
CAUTION: Cautions contain information to prevent
damage to equipment or software. Read
these carefully.
IMPORTANT: Important notations contain information to
allow your system to work properly.
OpenVMS This designation represents the OpenVMS
Alpha AXP operating system.
DEC OSF/1 This designation represents the DEC OSF
/1 Alpha AXP operating system.
Italics Italics are used for emphasis or to indicate
the title of a manual.

IMPORTANT:
Software
Product
Descriptions
The Software Product Description (SPD) is the official defining
document for software products licensed by Digital Equipment
Corporation, including third-party products licensed by Digital.
An SPD describes all important functional characteristics of the
software. The terms and conditions under which the corporation
sells and licenses its software products identify SPDs as the
documents that specify Digital’s obligation under software
warranty.
SPDs also describe a software product’s system environment,
and identify required and optional hardware and software. All
information contained in the SPD is valid in the international
marketplace.
For more information on the SPD for your operating system,
please contact your Digital sales representative.

Options Overview
External Options
A number of options are available for the system. Some, such
as drives and modules, are internal options. Others, such as a
printer or modem, are external options connected to the system
by a cable.
This chapter lists and illustrates internal options for the system
and shows where to install them in the system unit.
Options Overview 1–1

Internal Options
Internal Options
Drives Your system unit can hold up to two half-height removable-
media drives, that is, drives from which the storage medium is
removable. To add more than two removable-media drives, you
will need an expansion box.
In addition to the removable-media drives, you can have up to
four half-height fixed disk drives in the system unit.

Preparing to Add Internal Options
IMPORTANT: Read First
It is important to read this chapter before you install any of the
internal options described in this guide.
Chapter Overview
This chapter covers the following information:
• Going to Console Mode
• Displaying the Configuration
• Shutting Down Hardware
• Removing Panels
• Using an Antistatic Wrist Strap
Preparing to Add Internal Options 2–1

Going to Console Mode
Going to Console Mode
Back Up Your
Files If files are stored on a system disk, back them up following the
instructions in your software documentation.
Shut Down
Software The procedure for shutting down your software will depend on
whether or not your system is networked.
If you are... See your...
Networked, or part of a cluster, system manager.
Not networked, not part of a cluster, software documentation.
Not sure whether you are networked, system manager.
2–2 Preparing to Add Internal Options

Going to Console Mode
Press the Halt
Button If you are not already in console mode (>>> prompt) after
shutting down the software, put the system into console mode by
pressing the halt button. The halt button is behind the door, as
shown in Figure 2–1. The console prompt (>>>) should appear
on the monitor.

How to Read
the show
device Display
You should see the SCSI address for each drive in the ADDR
column, as shown in Figure 2–2. The drive model is shown
in the DEVNAM column. In this example, A/3/0 indicates an
address of 3 on the SCSI-A (internal device) bus for an RZ25
drive. B/7 indicates the initiator (SCSI controller) for the SCSI-B
(external device) bus.
You can have only one of each address (0-6) on each SCSI bus.
Use the show device output to choose an unused SCSI address
for drives you add to your system.
