Introduction
1.1 Scope
This manual is for the user and operator of the RRD40 Optical Disc Drive.
The RRD40 is a read-only storage device that reads data stored on removable
optical discs. An optical disc is 4.7 inches in diameter and can store 600
megabytes (about 600 million characters) of data.
In optical storage devices, data (which is stored on the disc) is read off of the
disc by a laser system. A laser is a concentrated beam of light. In the RRD40,
the laser (contained in the RRD40 disc drive) shines light on the disc. The
intensity of the light reflected back (to the laser from the disc) determines the
data on the disc. The concentrated beam of light from the laser is so fine that
it is possible to store massive amounts of data on a single disc.
1.2 Product Variations
There are two RRD40 drives that use one of two interfaces.

1-2 Introduction
1.2.1 Drives
The RRD40 is available as a tabletop version or a "half-height" version. The
half-height version is designed to be embedded into an existing host system
enclosure. Figure 1-1 and Figure 1-2 show the two RRD40 drives. Although
the two are physically different, they are functionally the same.

1.2.2 Interfaces
The RRD40 has two possible interfaces: Q-Bus and SCSI.
An RRD40 with a Q-Bus interface uses the M7552 controller module as the
interface to the host system. The Q-Bus interface is used in only the tabletop
version of the RRD40 drive.
An RRD40 with the SCSI interface uses a SCSI controller module as the
interface to the host system. The SCSI controller connects to the SCSI adapter
in the host system and functions as a SCSI device on the host system. An
RRD40 with the SCSI interface is available for both the Tabletop and Half-
Height RRD40 drives.

Installation
This chapter gives instructions on how to install the RRD40 Disc Drive.
Most of the instructions deal with the installation of the Tabletop RRD40; the
installation of the Half-Height RRD40 is covered briefly.
2.1 Half-Height RRD40 Installation
The Half-Height RRD40 comes with a SCSI interface only. This version
of the drive is generally not customer installable. This section gives some
general installation information, but refer to the host system documentation
for specific installation instructions.
The installation of the Half-Height RRD40 into the host system unit is
dependent on the system enclosure and also the current configuration of the
host system.
If you are installing a Tabletop RRD40, go to Section 2.2.
2-1

2-2 Installation
2.1.1 Assigning a SCSI Address ID Number
Locate the switch pack on the SCSI controller module (refer to Figure 2-1).
The switch pack can be assigned any number 0- 7. The four DIP switches on
the switch pack are numbered 1-4. Switch 1 sets the most significant bit, and
switch 3 sets the least significant bit. Switch 4 is unused. The board comes
preset to ID number 0 (all switches down).

Installation 2-3
Proceed as follows:
1. Determine the SCSI Address ID number that your RRD40 will be
assigned. This number is based on the current configuration of the
host system and can be any number 0-7. Refer to your host system
documentation for more information on the SCSI Address ID numbers.
2. Set the switch pack to the correct ID number. Table 2-1 gives the
settings for each of the eight possible ID numbers that the controller can
be assigned. Use a ball point pen or pointed object to set the switches.
NEVER USE A PENCIL TO SET THE SWITCH PACK. The graphite
used in pencils can damage the switch pack.

2-4 Installation
2.1.2 Cabling the Half-Height RRD40
The Half-Height RRD40 is embedded inside the host system enclosure and
is cabled internally. Refer to the host system documentation.
2.1.3 Testing the Half-Height RRD40
The Half-Height RRD40 uses a SCSI interface and responds to the same
testing as the other SCSI devices on the host system. Refer to the host system
documentation.
2.2 Tabletop RRD40 Installation
The Tabletop RRD40 comes with either a Q-Bus or SCSI interface. The
RRD40 rear panels are different for each interface, but the installation
procedures are similar. Figure 2-2 shows both rear panels.
The RRD40 with the Q-Bus interface has only one cable connector on the
rear panel. The RRD40 with the SCSI interface has two cable connectors on
the rear panel. There are two cable connectors because SCSI RRD40's can
be "daisy-chained" together. Refer to Section 2.2.3 for more information on
the cable connectors.
2.2.1 Equipment
The equipment necessary to install the Tabletop RRD40 depends on which
interface (SCSI or Q-Bus) your RRD40 uses. Table 2-2 lists the parts
needed for each installation. Make sure that you have all parts necessary for
installation before proceeding.
Note that if your RRD40 uses the Q-Bus interface, the M7552 controller
module should have already been installed into the host system by a specially
trained Digital Field Service Engineer.

2.2.2 Voltage Selecting
The rear panel of the RRD40 contains a voltage selector that can be set to
one of two voltages (110 V or 220 V). Figure 2-2 shows the location of the
selector on the rear panel. Verify that the voltage that your RRD40 is set
to is the correct voltage for your power requirements before powering
up the drive.
To change the setting of the voltage selector, insert a flat object (such as a
screwdriver) into the selector and turn so the desired voltage is facing up. In
Figure 2-2, the selected voltage is 110 V.
2.2.3 Cabling the Tabletop RRD40
The cabling is different depending on which interface your RRD40 uses. The
Q-Bus interface is a simple connection from the rear of the drive to the host
system. The SCSI interface requires a terminator assembly.
0-Bus Interface
The cabling for the Q-Bus interface depends on the host system.
Some host systems (such as the MicroVAX 3000 series) have a cable
connected directly to the controller module in the host system. This cable
comes out of the rear of the host system and must be installed into the
interface connector on the rear of the RRD40 drive. The cable is tightened
onto the connector by hand. The rear panel of the RRD40 drive is shown in
Figure 2-2.
Other host systems (such as the MicroVAX II) have an RRD40 bulkhead on
the rear patch panel of the system. This bulkhead has two connectors marked
"A" and "B". If this is the first RRD40 to be attached to the controller, then
you would attach the cable to the "A" connector. The cable is tightened onto
the connector by hand at both ends. Connect the cable to the host system
first, and then to the rear of the RRD40 drive. The cabling is shown in
Figure 2-3.

lnslallation 2-7
Figure 2-3 Cabling: 0-Bus Interface
SCSI Interface
An RRD40 which uses the SCSI interface has two cable connectors on the
rear panel (shown in Figure 2-2). The SCSI interface allows for connecting
multiple drives in a daisy-chain configuration. Because of this option, the
final drive in the chain must be "terminated". The terminator is simply a
connector for the unused rear panel interface connector on the drive. It is the
same as the connector on the I/O cable.
If you have only one drive, the external I/0 cable is connected from the host
system to the top connector on the RRD40 drive. The terminator is then
installed in the bottom connector on the rear panel of the drive.
If you have a second RRD40 drive, the external I/O cable for drive #2 goes
from the bottom connector of drive #1 to the top connector of drive #2. The
terminator is then installed into the bottom connector on the rear panel of
drive #2.
Follow the applicable instructions.

2~ Installation
Single drive cabling To cable a single drive, proceed as follows (refer to
Figure 2-4 ):
l. Connect the external 1/0 cable to the SCSI port on the rear of the host
system.
2. Connect the other end of the cable to the top connector on the rear of the
drive.
3. Install a terminator assembly into the unused (bottom) connector on the
rear of the RRD40.

Installation 2-9
Multiple drive cabling If you already have an RRD40 drive on the
system, and you want to add another RRD40, then a "daisy-chain" cabling
configuration is used. To daisy-chain a drive is to connect the new drive to
the RRD40 that is already connected to the host system.
To daisy-chain a new drive to a previously connected drive, proceed as
follows (refer to Figure 2-5):
1. Remove the terminator from the bottom connector of the RRD40 that is
already connected to the host system.
2. Take the external I/O cable for the RRD40 drive that you are installing.
Install one end into the open connector (the connector that you just
removed the terminator from).
3. Install the other end of the I/O cable into the top connector of the "new"
RRD40 (the drive that you are installing).
4. Install the terminator into the unused (bottom) interface connector on the
RRD40 you are installing.

2-10 Installation
2.2.4 Installing the Power Cord/Verifying Power
1. Make sure that the power switch on the rear panel of the RRD40 is set
to the OFF (0) position (refer to Figure 2-2).
2. Install the female end of the power cord into the receptacle on the rear of
the drive.
3. Install the other end of the power cord into a wall outlet rated for the
correct voltage. Make sure the voltage selector is properly set.
4. Tum the rear panel power switch to the ON (I) position and verify that
the POWER indicator on the front panel lights.
If the POWER indicator does not light, then a problem exists. Set the
POWER switch back to the OFF (0) position. Verify that the wall outlet
has power, and try again. If the indicator still fails to light, contact your
Digital Service Representative before proceeding any further.
2.2.5 Assigning an Address ID/Unit Number
For the SCSI interface, you must assign the drive a SCSI Address ID number.
For the Q-Bus interface, you must assign the drive a unit number. Follow the
instructions that apply.
SCSI Interface
Locate the switch pack on the rear of the SCSI Tabletop RRD40 (shown in
Figure 2-2). This switch pack sets the SCSI Address ID number that the
RRD40 will respond to in the host system. The drive must be given a SCSI
Address ID number by setting the switch pack. The four DIP switches on
the switch pack are numbered 1-4. Switch I sets the most significant bit, and
switch 3 sets the least significant bit. Switch 4 is unused. The board comes
preset to Address ID number 0 (all switches down).
Proceed as follows:
I. Power down the drive.
2. Determine the SCSI Address ID number that your RRD40 will be
assigned. This number is based on the current configuration of the
host system and can be any number 0-7. Refer to your host system
documentation for more information on the SCSI Address ID numbers.
