Preface

This manual provides service and diagnostic procedures for DECmpp 12000/Sx

systems. Anyone who services DECmpp 12000/Sx Series systems or needs to

replace any items should read this manual and be familiar with the procedures.

Intended Audience

This guide is for use by Digital Services personnel and by self-maintenance

customers who will be servicing the DECmpp 12000 and DECmpp 12000–LC

systems.

Document Structure

The DECmpp 12000/Sx Hardware Service Manual contains seven chapters and

two appendixes.

• Chapter 1 is a system overview and contains the power-up and power-down

routines for both the data parallel unit (DPU) and the front-end server.

• Chapter 2 describes the DPU switches, controls, indicators, and the DPU

power system.

• Chapter 3 describes the DPU power supply settings and how to adjust them,

if necessary.

• Chapter 4 describes the DECmpp 12000/Sx system cables, connectors, and the

printed circuit boards (PCBs) outside the DPU card cage.

• Chapter 5 describes the diagnostic software provided, how to use it, and how

to interpret the results.

• Chapter 6 explains the procedures for removing and replacing the DPU

components.

• Chapter 7 explains the procedures for upgrading the DECmpp 12000/Sx

Series systems by adding more processor element (PE) array PCBs.

• Appendix A lists all of the recommended spare parts for the DPU.

• Appendix B is a collection of Reference Pages that apply to the DPU.

Conventions

The following conventions are used throughout the DECmpp 12000/Sx

documentation set:

Convention Meaning

Return In examples, a key name shown within a box indicates that

you press a key on the keyboard. In text, a key name is not

enclosed in a box but is printed with an initial capital letter,

like Return.

Ctrl/xA key combination, shown with a slash separating the two key

names, indicates that you hold down the ﬁrst key while you

press the second key.

MB1, MB2, MB3 The buttons on a mouse. MB1 is the left button, MB2 is the

center button, and MB3 is the right button of a mouse whose

button arrangement is right-handed. It is possible to redeﬁne

the mouse buttons.

% A percent sign (%) represents the default user prompt for your

system.

# A number sign (#) represents the default superuser (root)

prompt for your system.

...

In examples, a horizontal series of dots, or ellipsis, indicates

that additional parameters, values, or other information can be

entered.

.In examples, a vertical series of dots, or vertical ellipsis,

indicates that a portion of the example is intentionally omitted.

[] In syntax descriptions and functional descriptions, brackets

indicate optional items.

dpumanager(6)

Cross-references to the ULTRIX Reference Pages, which include

the appropriate section number in parentheses.

italicized text In examples, italicized text denotes parameters, values, or

other information that will change from either session to

session or user to user. In text, italicized words or phrases are

used to add emphasis to important words, concepts, or titles of

manuals.

ULTRIX keywords

This typeface is used to indicate system output or the exact

name of a command, option, partition, pathname, directory, or

ﬁle.

Code examples

This typeface is used to display program coding examples.

UPPERCASE and

lowercase strings The ULTRIX system differentiates between lowercase and

uppercase characters. Literal strings that appear in text,

examples, syntax descriptions, and function descriptions must

be entered exactly as shown.

Both the DECmpp 12000/Sx and DECmpp 12000–LC/Sx Series hardware systems

are described in this manual. However, because the two systems are very similar,

references to the DECmpp 12000 system also apply to the DECmpp 12000–LC

system, unless speciﬁc differences between the two systems are noted.

Three types of notes are used in this manual:

•Note

Gives additional information or information particularly important to the

procedure.

•Caution

Indicates potential damage to equipment or data.

•Warning

Indicates potential injury to a person.
