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.

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.

RRD40 Half-Height Drive

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 HalfHeight 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.

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).

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.

2.1.2 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.

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.

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.

2.2.4 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.

Installation 2-11

3. Set the switch pack to the correct Address ID number. Table 2-1 gives
the settings for each of the eight possible 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.

4. Verify power again by following step 4 in Section 2.2.4.
0-Bus Interface
For the Q-Bus interface, the unit number is set through the MicroVAX
Diagnostic Monitor (MOM). Instructions for running MOM are given in
Chapter 4. The RRD40 drive comes preset to unit number 0. If you are
assigning the RRD40 drive unit number 0, you need not run the Utility.
If you want to set the RRD40 to a unit number other than unit number 0,
proceed as follows.
I.

Refer to Chapter 4 and load the MicroVAX Diagnostic Monitor.

2. At the Main Menu (shown in Section 4.2), select Option #3: Display
System Utilities Menu. This will put you into the Utility that sets the
unit number.
3. Follow the step by step instructions to set the unit number.
4. Return to the Main Menu and exit out of MOM by selecting Option #5.

2.2.6 Testing the Tabletop RRD40
The Tabletop RRD40 that uses a SCSI interface responds to the same testing
as the other SCSI devices on the host system. Refer to the host system
documentation.
The Tabletop RRD40 that uses the Q-Bus interface is tested through the
MicroVAX Diagnostic Monitor (MOM). Refer to Chapter 4 for instructions
on running RRD40 tests through MOM.

3.2 Loading a Disc
When loading a disc, the entire disc caddy is inserted into the disc opening
on the front of the drive. DO NOT remove the disc from the caddy! Proceed
as follows:
I.

Make sure the power is on. On the Tabletop RRD40, this is indicated by
the front panel POWER indicator being lit. On the Half-Height RRD40,
make sure that the host system power is on.
It is important that power has been applied to the RRD40 drive before
you load a disc.

Note that the disc is housed inside a protective caddy. Examine the disc
caddy. Make sure that it is not cracked or damaged in any way. NEVER
LOAD A DAMAGED CADDY INTO AN RRD40 DRIVE!

3
Operation
There are two variations of the RRD40: Tabletop and Half-Height (shown
in Figure 1-1 and Figure 1-2). The Tabletop RRD40 connects to the host
system via an external I/O cable. The Half-Height RRD40 is installed in
the host system box and is connected internally. Operating the drive is the
same whether you have the Tabletop or Half-Height version.

3.1 Front Panel
The front panel consists of a disc opening and one or two status indicators.
The Tabletop RRD40 contains a POWER indicator and an ACTIVITY
indicator (shown in Figure 3-1). The Half-Height RRD40 contains only the
ACTIVITY indicator. There is no POWER indicator on the Half-Height drive
because there is no power switch.
The POWER indicator on the Tabletop RRD40 lights when power is applied
to the RRD40 (via the rear panel POWER switch). Refer to Chapter 2 for
descriptions and illustrations of the rear panel.
The ACTIVITY indicator (present on both versions) lights solid when a
disc is correctly loaded into the RRD40 drive. When an RRD40 disc is
transferring data, the ACTIVITY indicator flashes.

3. Examine the disc inside the caddy. DO NOT REMOVE THE DISC
FROM THE CADDY. Note that one side of the disc is labeled. The label
should always be facing up as you insert the disc into the drive. When
the label is facing up, the four notches on the disc housing will be on
the left, as shown in Figure 3-2. These notches line up with four similar
notches on the front of the RRD40, as shown in Figure 3-1.
NOTE: If you have the disc positioned label side up and the notches are
on the right, then the disc is oriented incorrectly in the caddy. Do not
proceed any further with the disc loading. Go to Section 3 .4 on disc and
caddy repairing.
4.

Insert the disc caddy as shown in Figure 3-2. Make sure the notches
on the left side of the disc caddy line up with the notches on the disc
opening on the front of the drive. Slide the caddy in as far as it will go.

5. Remove the caddy. When removed, you will notice that the disc and its
housing remain in the drive. Only the transparent sleeve comes out.
6. Check that the front panel ACTIVITY indicator lights solid within five
seconds.
If the drive accepted the disc but the ACTIVITY indicator does not light,
then the disc may have been oriented in the caddy incorrectly. Unload
the disc using the instructions in the following section. Then, refer back
to Step 3 and examine the disc orientation in the caddy.

3.3 Unloading a Disc
Before unloading a disc, make sure that the ACTIVITY indicator is not
flashing. If it is flashing, then the RRD40 is transferring data. Wait until the
indicator stops flashing.
The unloading procedure is a reverse of the loading procedure. Use Figure 3-2
as a guide.
I.

Orient the transparent sleeve for loading. Make sure the arrow on the
sleeve is pointing towards the drive.

2. Insert the sleeve into the disc opening on the front of the drive as far as
it will go.
3. Remove the caddy. The disc and housing will be back in the sleeve. The
ACTIVITY indicator will go out.

3.4 Disc and Caddy Repairing
The RRD40 media is contained inside a protective caddy. The caddy consists
of three parts: the disc, the disc housing, and the transparent sleeve (see
Figure 3-3).
If the transparent sleeve is damaged or cracked or if the disc needs cleaning,

the caddy can be taken apart and replaced if necessary.
It is important that the disc is mounted in the caddy correctly. Failure
to mount the disc correctly will make the disc inaccessible by the host
computer.

Operation

3.4.1 Removing the Disc from the Caddy
To remove the disc from the caddy for cleaning or caddy repairing, proceed
as follows:
1.

Hold the caddy so that the label on the disc is facing down. Locate the
locking tabs on either side of the disc housing, as shown in Figure 3-4.

2. For each locking tab, press down on the tab while slightly separating the
housing from the sleeve. Use your fingernail or a pointed instrument.
When both tabs have been disengaged, pull the disc housing out to about
the midpoint of the disc (Figure 3-5).
3. Hold the disc housing on each side as shown in Figure 3-5. Exert slight
inward pressure on the housing so the disc will not fall out. Remove the
sleeve from the housing. Place the sleeve aside.

4. Grasp the disc with your free hand as shown in Figure 3--6. Position your
thumb on the outer edge of the disc and your index finger in the center
hole of the disc. Release pressure from the housing and remove the disc.

3.4.2 Cleaning a Disc
The disc can be cleaned with a dry, lint-free cloth. The disc should always be
free of dust, dirt, and fingerprints. Always hold a disc by the edges. Never
touch the data area of the disc.
To clean, always wipe from the center of the disc to the edges. Use small
circular strokes. Do not use a continuous circular stroke around the disc.

3.4.3 Replacing the Disc in the Caddy
Assembling the caddy is essentially a reverse of the procedures given in
Section 3.4.1. Make sure that your hands are positioned as shown in the
illustrations. It is important that you replace the disc correctly.

1. Position the housing and disc EXACTLY as shown in Figure 3-6. (Make
sure the label on the disc is facing DOWN.)
2. Insert the disc into the housing. The inside of the housing is grooved
to accept the disc. Exert slight inward pressure to hold the disc in the
housing.
3. With your free hand, get the transparent sleeve. Notice that the sleeve
is symmetrical. Slide the housing all the way into the transparent sleeve
until it clicks into place.
4. Tum the assembled caddy over so that the label on the disc is facing up.
Examine the housing. When the caddy is loaded into a drive, the notches
on the caddy are in the upper left hand comer. These notches line up
with the notches on the drive (Figure 3-1 ).
If the notches are not on the left side when the caddy is positioned for
loading (label side of the disc up), then the disc is mounted inside the
caddy incorrectly! Remove the disc from the caddy and orient it properly.
It is extremely important that the disc is mounted inside the caddy
correctly. The RRD40 drive cannot access data from a disc that is
mounted incorrectly I

Testing the RRD40 on a MicroVAX
This chapter gives instructions on how to test the RRD40 Subsystem through
the MicroVAX Diagnostic Monitor (MDM). These tests work only on
MicroVAX host systems (Q-Bus interface). The RRD40 with the SCSI
interface is tested through the host system. The procedures for testing all
SCSI devices apply to the RRD40. Refer to the testing sections in the host
system documentation.

4.1 Running Tests on MicroVAX Host Systems
Testing on the MicroVAX is done through the MicroVAX Diagnostic Monitor
(MDM). The monitor is used by service personnel as well as MicroVAX
customers. This chapter gives a brief outline of MDM as it applies to
customers and service personnel. However, if you need more information
about MDM, please consult Digital's MicroVAX Diagnostic Monitor User
Guide (part number AA-FM7AA) which contains details on rwming all modes
ofMDM.
To run RRD40 tests on the MicroVAX, you need the MicroVAX Diagnostic
Monitor (MDM) Diagnostic Kit. Use the floppy that contains the RRD40
diagnostics from the kit. Unless you have purchased a MicroVAX
Maintenance Kit, you will be limited in the diagnostics you will be able to
run. The MicroVAX Maintenance Kit contains the necessary license that
allows you to run extensive system tests.
For more information on purchasing the MicroVAX Maintenance Kit, contact
your Digital Service Representative.

4.3.6 Error Reports
If a test fails, an error message displays.

EXAMPLE: During verify mode testing (with DETAILED MESSAGE OFF),
the RRD40 Drive Microdiagnostics Test (Test 11) failed. The following
appears on the screen:
RRDXXA -- Error Number 1103
RRDSO/RRD40 DRIVE FAILED MICRODIAGNOSTIC TEST
RRD50/RRD40 CABLE/DRIVE A

The four-digit error number (code) that is given on the screen has the
following format.
TTSS:
where TT is the test number (defined in Table 4--1 and Table 4--2), and SS is
the section of the test that failed.

In the previous example, the error number is 1103. This means that Test 11
(Microdiagnostic Test), Section 3, failed.
DETAILED ERROR REPORT

When SET DETAILED MESSAGE ON is set in service mode, a detailed
error report displays if a test fails. This error report is for use by specially
trained technicians and field engineers.
If two disc drives exist on one controller, this report also defines which one
of the two drives on that controller failed. The report identifies the two
drives by port number. Port A is the drive attached to the A connector on
the connector panel. Port B is the drive attached to the B connector on the
connector panel.

The detailed error report defines the failed test, giving specific error codes for
the disc drive or controller, whichever applies. Drive error codes are listed in
Table 4--5. Controller error codes are listed in Table 4--6.
WHAT TO DO WHEN A TEST FAILS
When a test fails, always try again. If the test fails twice, contact your Digital

service representative. Your service representative will instruct you on what
to do.
Remember that you cannot replace the controller or any of its associated
cables on Q-Bus host systems. You may void your service contract by
opening up your host system. 1f you have questions on your contract
limitations, call your Digital service representative or call 1-800-DIGITAL.
