SAFETY

SUMMARY

The

following

general

safety

precautions

must

be

observed

during

all

this instrument.

Failure

to

comply

with

these

precautions

or

with

specific

warnings

elsewhere

in

this

manual

violates

safety

standards

of

design,

manufacture,

and

intended

use

of

the

instrument.

Hewlett-Packard

Company

assumes

no

liability for

the

customer's

failure

to

must

either

be

plugg-

ed

into

an

approved

three-contact

electrical

outlet

or used

with

a

three-contact

to

two-contact

adapter

with

the

grounding

wire

(green)

firmly

connected

to

an electrical ground (safety ground)

at

the

power

outlet.

The

Operating personnel

must

not

remove

instrument

covers.

Component

replacement and internal

adjustments

must

be

made

personnel.

Do

not

replace

components

with

power

cable

con-

nected.

Under

certain

conditions,

dangerous voltages

may

exist

even

with

the

power

cable removed.

avoid injuries,

always

disconnect

power

and discharge

circuits

before

touching

them.

DO

NOT

instrument

to

a

Hewlett-Packard

Sales and Ser-

vice

Office

for

service and repair

to

ensure

that

safety

features

are maintained.

Introduction

Installing the

HP

3235

This manual provides instructions

for

service-trained personnel to install the

HP 3235 Switch/Test Unit (STU) and Switch/Test

Unit

Extenders. Installation

is

in two parts:

1.

Procedures required

to

set-up the STU system and begin using the

HP

3235

User Training Guide.

2.

Procedures

that

are application dependent and follow initial set-up, training,

and familiarization with the STU system.

Following

is

a summary

of

the procedures contained in each

part

• Set the power requirements on the mainframe (line voltage, fuse,

etc.).

NOTE: Extender frames are not required

for

training.

• Set the frame address

to

zero on the mainframe.

• Connect

the

HP-IB interface from mainframe

to

your system controller.

• Connect the optional control panel (if you have one)

to

the mainframe.

• Install plug-in modules in the mainframe and record the slot number

they

are installed

in.

• Apply power

to

the mainframe.

After completing the installation procedures

of

Part

1,

the system

is

now set up

for

you

to

begin

the

training lessons

in

the User Training Guide (HP

P/N

03235-90006). When finished with the training lessons, you will have an under-

standing

of

the

STU and plug-in module operation.

At

this time, you define

the

test requirement/STU system cabling and proceed with the installation

procedures

of

Part

2.

Part

luslallalion

procedm·es

thai

are application dependent.

• Floating user side ground.

• Installing extender frames if part

of

the system.

• Installing a Bus Access module (mainframe only system).

• Installing Extender modules and digital extender cables (mainframe with

extender frame system).

• Installing analog bus extender cables.

• Installing feedthrough panels.

• Terminal block preparation and connection

of

field wiring.

• Connecting terminal blocks

to

modules.

• Installing

the

optional quick interconnect fixture.

• Rack mounting mainframes

or

extenders.

• Rack mounting the optional control panel.

STU

Description

Installing the

HP

3235

4

The

HP

3235 Switch/Test Unit (STU)

is

a 10-slot programmable mainframe.

There are

two

sideYs

to

the

STU:

the

system side

and

the

user's side.

The

system

side contains the system modules (crossguard, processor, controller interface,

bus

access

or

option 560

extender

module, and

power

supply). Frames

are

shipped

with all system modules insta1led except the

bus

access or extender n1odules.

Figure 3 shows

the

system side with an option 560

Extender

module installed (has

two

digital extender connectors).

Various plug-in modules

for

the user side can

be

selected

to

fit

your application.

You install these modules into the user side card cage and

connect

the field

wiring to terminal blocks which mate to the modules. Figure 3 shows the

user

side with the

option

590 quick interconnect mechanism handles visible.

If

more

than ten modules

are

required, an STU Extender

can

be

added

to

the

system

providing ten more slots (you

can

add up

to

seven extenders

to

a mainframe).

Procedures

for

connecting extenders in

the

system are

contained

in

the

part

2 in-

stallation procedures.

parts) are missing

or

were damaged in transit, im-

mediately report the problem

to

your local HP sales

office

(see the list in

the

back

of

the carrier. If the shipping container

or

is

damaged,

it

should

be kept until the contents

of

the shipment have been checked

for

completeness

and

the instrument(s) have been mechanically and electronically inspected.

on

the HP 3235 self test

is

fcaturc.J·

are

maintained.

Each HP 3235 has a serial number located on a plate beneath

the

fan

grill

on

the

system side. This serial number has the

form

XXXXAYYYYY

where

XXXX

is

the serial number prefix, A

is

the country

of

origin

(A

= USA),

and

YYYYY

is

the serial suffix.

Each plug-in module and system module has a serial number located

on

a label

on the module. The serial number has the

form

XXXXAYYYYY like

the

HP

3235 frame. An ERC (engineering revision code) label

is

also

on

each plug-in

module. The ERC number changes with any circuit modification to

identify

the

circuit version present.

We recommend you keep a separate record

for

these serial numbers. Should

your instrument(s)

be

lost

or

stolen, the complete serial number

is

often

necessary

for

tracing, recovery, and insurance claims.

You may have your

HP

3235 and plug-in modules repaired

at

an

HP

service cen-

ter at any time, whether under warranty or not. There

is

a charge

for

repairs

af-

ter the warranty period. Contact your local HP Sales and Service

Office

for

in-

structions prior to shipping the instrument. A list

of

Sales

and

Service Offices

is

located at the back

of

this manual.

Should you ever need

to

ship your HP 3235, remove the plug-in modules

from

the user side

of

the frame and package them separately. Use clean handling and

antistatic techniques when removing, handling, and packaging

the

plug-in

modules. WRAP

THE

MODULES

IN

ANTISTATIC BAGS. Be certain

that

the

mainframe and each module

is

packaged

in

a protective package (use

the

original

shipping container and cushioning material if possible)

to

avoid transit damage.

Such damage

is

not covered by warranty.

Attach a tag to the instrument

or

module identifying the

owner

and

indicating

the service

or

repair needed. Include the model and serial

number

of

the

instru-

ment

and/or

plug-in modules. In any correspondence, identify

the

instrument by

model number and full serial number. We suggest that you always insure ship-

ments.
