1-1. INTRODUCTION

This section contains verification procedures

that

are

extracts

from stand-alone diagnostics to provide

quick, easy to

run

diagnostics

that

verify system operation.

1-2. DIAGNOSTIC AND VERIFICATION PROGRAMS

The

HP

3000 Series II Computer System uses

three

types of

test

programs. They

are

ON-LINE

VERIFICATION PROGRAMS, STAND-ALONE DIAGNOSTICS,

and

MICRODIAGNOSTICS.

1-3. ON-LINE

VERIFICATION

PROGRAMS

The

on-line verification programs

are

used to confirm proper operationofperipheral

devices (i.e.

printer,

terminals,

readers, punches etc). These programs

run

concurrently

with

other

programs

under

controlofthe

Multiprogramming Executive Ope'tating System (MPE)

and

permit

uninterrupted

system operation.Ifthe

minimum

hardware

configuration required for MPE is inoperable, on-line

verification programs

cannot

be run. The stand-alone diagnostics

must

then

be used.

The

verification

programs

are

describedinthe

Manual

of On-Line Verification Programs. The verification

programs

and

their

manual

part

numbers

are

listed in

table

1-1. Access to

the

verification programs is obtained

by

entering

account.

1-4. STAND-ALONE DIAGNOSTIC

PROGRAMS

The stand-alone diagnostic programs allow Customer Engineerstorun

maintenance

and

trouble-

shooting tests on system

hardware

and

peripheral

devices.

Eachofthese

programs

is independently-

operated

and

runs

directly on

the

central

processor. MPE is

not

required

and

the

operating

system

is

DEC

I

System Service

shut-down while stand-alone programs

are

running.

When a problem occurs

that

prevents

the

use

of

both on-lineorstand-alone programs,

then

the

microdiagnostics

can

be used.

The

stand-alone diag-

nostics

are

describedinthe

Manual

ofStand-Alone Diagnostics. The stand-alone programs

and

their

manual

part

numbers

are

listed

in

table

1-2. The

CPU

diagnostic (D420) is available from

the

CPU-Cold Load tape,

part

number

30000-10016 (11016).

(-11016

is a 1600 BPI tape.)

The

stand-alone diagnostic tapes

are

created

under

control of SDUPII (Standalone Diagnostic

Utility

Program

II). Updating stand-alone diagnostics is also accomplished

under

controlofSDUPII.

For

detailed information on

the

use

and

functions of SDUPII, refer to

The

microdiagnostics

are

microprograms

that

are

built

into

the

system. These

are

microprograms

that

replace

the

instruction

set

microprogramsinthe

central

processor

and

,in some controllers. They

identify problems by checking

the

hardware

from

the

most

basic level.

PROCEDURES

I III I

3-1. PURPOSE OF MAINTENANCE PANEL

The

HP

30354A

Maintenance

Panel

(figure 3-1) is a

troubleshooting

aid

for

the

HP

3000

Series

II

Computer

System.

When

the

Maintenance

Panel

is connected to

the

system,

switchesonthe

panel

are

used

to select specific

registers

whose

content

may

be observedorchangedtoassistinlocalizing

system

faults.

Additionally,

lampsonthe

Maintenance

Panel

show

the

contentsofmany

computer

registers

and

the

stateofprincipal

signals,

allowing

analysisofsystem

functioning. (For

the

most

part,

the

visual

displays

are

used

only

when

the

computerishalted.)

Operating

powerisprovidedbythe

computer

system.Aninterface

PCA,

installedinthe

CPU

card

cage,isrequired

for

the

Maintenance

Panel.

The

namesofswitches

and

indicatorsonthe

Maintenance

Panel

are

markedonan

overlay

which

installs

on

the

faceofthe

unit.Asmaller

overlay

(the I/O overlay)

can

be placed

overacertain

row

oflamp

names

on

the

main

overlaytoextend

the

display

functionofthose

lamps.Aswitch

permits

displayofthe

signals

namedonthe

small

overlay;

other

displays

remain

unchanged.

The

small

overlay

canbeturned

over

to

provide

another

setofnames;

these

signals

are

displayedbymaKinganadditional

cable connection to

the

computer

system.

As wellasbeing

used

for

equipment

fault

finding,

the

Maintenance

Panel

can

be employed for

debugging

computer

programs.

However,

the

Maintenance

Panelisnot

intended

for

programmers.(Asoftware

debug

packageisavailable

for

programmers'

use.)

The

Maintenance

Panel

has

a self-test

capability

which

allows

the

operabilityofmost

circuitsinthe

Maintenance

Panel

to be verified

without

the

useoftest

equipment.

3-3. ADDITIONAL EQUIPMENT

A

switchonthe

Maintenance

Panel

allows use ofanexternal

pulse

generatorasthe

sourceofsystem

clock

pulses

for

the

CPU.

This

permits

the

CPUtobe

runata

rate

slowerorfaster

than

normal,

and

allows

the

pulse

widthtobe

varied.

The

changeinoperating

speed

and

pulse

width

makes

certain

types

of

intermittent

failure

become

steady

faults,

simplifying troubleshooting.

The

pulse

generator

maybeof

type.

The

USE

To

equal the internal clock-pulse rate, the external clock-pulse

frequency must be 22.8571 MHz. This corresponds to a period of

43.75 nsec, which, because of a divide-by-four

actioninthe CPU,

provides a 175-nsec computer clock cycle.

The

external clock-pulseissupplied to a BNC-type connector on

the

CPU

backplane.

The

connectorislabelled

EXT

- CLOCK. A

50-ohm termination impedance

is

providedinthe CPU.

In

the INHIBIT position, this switch permits the CPU to execute one

machine cycle each time the CLOCK SINGLE CYCLE switch

is

pressed.Inthe

positionofthe switch, the CPU operates continuously using either internal or external clock pulses.

When enabled by the CLOCK INHIBIT/FREE

SWITCH

TEST

The switchesonthe

maintenance

panel

canbetestedbyplacing

the

switch on

the

MPI

PCAtothe

SWITCH

TEST

position.

This

routes

the

switch

information

backtothe

maintenance

panel

to be

displayed by

lightingorextinguishing

oneormore

lamps

for each switch.

The

data

from

the

switches will

be displayed

by

nine

groups of lamps. See figure 3-5.

The

information

for

the

REGISTER SELECTION switches is coded into six

binary

bits. These

bits

are

displayed twice by

the

lampsingroup five.

Figure

3-5

illustrates

the

individual groups of

lamps

and

also

indicates by

each

switch

which lamp/lamps will

illuminateorextinguish

when

the

switch

is exercised.

Note:

Although

twelve groupsoflamps

are

designatedinfigure 3-5,

not

all

of

the

groups of

lamps

will be exercised

during

the

switch test.

Maintenance Panel Operating Procedures

The

bistable

switches, showninthe

down position, will

illuminate

the

lamp/lamps

indicatedbythe

numbers

above

the

switch

when

the

switch is placed up.

The

two-position

spring

return

switches,

shown

in

theupposition, will

extinguish

the

lamps

indicatedbythe

numbers

below

the

switch

when

the

switch

is

held

down.

The

three-position

spring

return

switches (REGISTER

SELECTION

switches)

have

a code

above

and

below

the

switch

that

will be displayed

when

the

switch is

heldinthat

position.

Stenciling

on

the

panel

has

not

been

shown

for clarity.

Where

two

pairsofnumbers

are

present,

two

lamps

will

be

illuminated.

For

example, 1,8

and

9,8 signify

that

group1lamp8and

group 9

lamp

8 will be

illuminated

when

the

switch

is exercised,

the

lamps

will

extinguish

when

the

switchisoff.

The

reverse

condition

applies to

the

two-position

spring

return

switches,

extinguishing

the

lamps

when

the

switch

is exercised.

When

exercising

the

REGISTER SELECTION switches, a

binary

coded

valueispresentedbythe

lamps

in

group

five.

The

coded

value

appears

twice,inbits

0-5

and

bits

8-13.

The

indications

presentedbybits

8-13 should be ignored.

CAUTION

After

the

switch

test

is complete, be

sure

all

bistable

switchesonthe

Maintenance

Panel

areinthe

downposition before

restoring

S1 on

the

MPI

PCAtothe

NORMAL position.

This

will

prevent

information

from

entering

the
