shows

the

physical

arrangement

of

the wired backplane, distribution

panel(s)

and

cables in a typical installation.

Figure

I

is

the

DV

11

interconnection schematic. Install

the

9-slot,

double

system unit in

the

expander

box

or

processor box as space

and

power

are

available.

With

power

off, test

the

resistances between all pins

of

the

power

harness

Mate-N-Lok

connector.

Only

pins

of

the

same

wire

color

should

be connected. Secure the

ground

wire

to

one

of

the

mounting

screws. Plug

in

the

Mate-N-Lok

connector

of

the

power

harness.

Apply

power

and

check for

proper

voltages

on

the

logic

pins

(not

the

cable) as follows:

Voltage

+5

± 0.25 V

-15

± 0.75 V

+15

± 0.75 V

Pin

CIA2

CIB2

CIUI

This

will

ensure

that

the

cable

and

the

Mate-N-Lok

connector

were correctly installed.

Turn

power

off.

(Note

that

the

DVII

is

not

yet

connected

to

the

Unibus,

nor

are

any modules installed.)

Install the distribution panel(s)

as

indicated in

Figure

2-1. Refer

to

Figure

2-7 for

the

proper

jumper

con-

figuration

of

the

distribution panel.
