1 The RRD43–AA CD-ROM Drive
The RRD43 CD-ROM drive is a compact disc, read-only memory (ROM), Small
Computer Systems Interface (SCSI) device. It reads data from industrystandard 600 MB discs. The order number for the field-installable RRD43
CD-ROM drive is RRD43–EK. Figure 1 shows the RRD43 drive and its
external features.

Documentation

3 SCSI ID Information
In any system, each SCSI device must have a unique identifier called the SCSI
ID number. In an RRD43 CD-ROM drive, the SCSI ID number is determined
by three jumpers (See Figure 2). When installing an RRD43 CD-ROM drive
in a system, set the SCSI ID jumpers to a value that is not used by any of the
other SCSI devices in the system. See your system documentation for more
information about the SCSI bus.
The following procedure describes how to set the SCSI ID number on an
RRD43 CD-ROM drive option.
1. Determine the SCSI ID number to be assigned to the RRD43 CD-ROM
drive option. Typically, the RRD43 CD-ROM uses SCSI ID 4; however, the
system manager may prefer to make this decision.
2. At the console prompt on the system console terminal, enter the SHOW
DEVICE command. This will list the SCSI ID numbers for the existing
devices in the system. Verify that you are using a number that is not
currently assigned to another device.
3. Locate the SCSI ID jumper pins on the CD-ROM drive. See Figure 2.

4. Position the jumpers for the SCSI ID number selected. Table 1 shows the
jumper settings for each SCSI ID.

A fourth jumper wire (Parity) resides to the right of the SCSI ID jumper
wires and must be installed. When the Parity jumper is installed, the drive
is in Digital operation mode. When the jumper is removed, the drive is in
PC mode.

4 Installation
Before installing the RRD43 CD-ROM drive option, the enclosure cover must
be removed. If you are installing the RRD43 CD-ROM drive option in a
MicroVAX 3100 Model 40, 80, or 90 system, or a VAX 4000 Model 100 system,
the upper drive-mounting shelf must also be removed. See the appropriate
enclosure maintenance manual for these removal procedures.
You can install an RRD43 CD-ROM drive in the following MicroVAX 3100 and
VAX 4000 Model 100 systems:
•

A MicroVAX 3100 Model 30 system (right storage slot.)

•

A MicroVAX 3100 Model 40, 80, or 90, or VAX 4000 Model 100 system
(either storage slot in the lower drive-mounting shelf.)

The location of the storage slot determines the position of the mounting bracket
on the drive. The following sections describe how the mounting bracket should
be attached to the CD-ROM drive.

4.1 Preparing to Install an RRD43 Option in a MicroVAX 3100 Model 30
System
Before you install an RRD43 CD-ROM in a MicroVAX 3100 Model 30 system,
perform the following steps:
1. Attach the mounting bracket as shown in Figure 2. Facing the front of the
drive, the captive screw should be on the left, and the four screws attaching
the mounting bracket to the drive should be attached through the series of
bracket holes that are closest to the front of the drive.
2. From inside the enclosure, push the blank bezel insert out of the front
bezel.
3. Remove the blank bezel insert from the enclosure. Figure 3 shows the
removal of the blank bezel insert from a MicroVAX 3100 Model 30 system.

4.2 Preparing to Install an RRD43 Option in a System (Right Storage
Slot)
Before you install an RRD43 CD-ROM drive option in the right storage slot
on the lower drive-mounting shelf in a MicroVAX 3100 Model 40, 80, or 90, or
VAX 4000 Model 100 system, perform the following steps:
1. Attach the mounting bracket as shown in Figure 2. Facing the front of the
drive, the captive screw should be on the left, and the four screws attaching
the mounting bracket to the drive should be attached through the series of
bracket holes that are closest to the front of the drive.

2. From inside the enclosure, push out the blank bezel insert that covers the
right storage slot on the lower drive-mounting shelf.
3. Remove the blank bezel insert from the enclosure.

4.3 Preparing to Install an RRD43 Option in a System (Left Storage
Slot)
Before you install an RRD43 CD-ROM drive option in the left storage slot on
the lower drive-mounting shelf in a MicroVAX 3100 Model 40, 80, or 90, or
VAX 4000 Model 100 system, perform the following steps:
1. Attach the mounting bracket as follows: Facing the front of the drive, the
captive screw should be on the right, and the four screws attaching the
mounting bracket to the drive should be attached through the series of
bracket holes that are closest to the front of the drive.
2. From inside the enclosure, push out the blank bezel insert that covers the
left storage slot on the lower drive-mounting shelf.
3. Remove the blank bezel insert from the enclosure.

4.4 Installing the RRD43 CD-ROM Option
After you have prepared the system as described previously, install the RRD43
CD-ROM drive option as follows:
1. Check the storage slot on the drive-mounting shelf to verify that all springlock clips are in the locked position. If they are in the released position,
install a lock-out screw to secure them down.
2. Identify the power cable connector that supplies power to the storage slot
where the RRD43 CD-ROM drive will be installed.
3. Connect the power cable to the power connector on the back of the RRD43
CD-ROM option. See Figure 4.
4. Identify the SCSI cable connector that has a pull-tab number that
corresponds to the storage slot where the RRD43 option will be installed.
5. Connect the SCSI cable to the back of the RRD43 option. See Figure 4.
6. Align the tabs on the mounting bracket with the cutouts in the drivemounting shelf.
7. Tilt the drive slightly to slide the tabs in the drive-mounting shelf cutouts.

8. Lower the CD-ROM into position and tighten the captive screw on the
mounting bracket to secure the tape drive in place. Figure 5 shows
the installation of an RRD43 option in the left storage slot of the lower
drive-mounting shelf.
Replace the upper drive-mounting shelf (if removed) and the enclosure cover.

5 Diagnostic Support
The systems provide diagnostic support that tests the operation of an RRD43
CD-ROM drive option.
•

If you are using a MicroVAX 3100 Model 30, 40, or 80 system, enter one of
the following commands at the console prompt to test the operation of the
RRD43 option:

Figure 5 Installing the RRD43 Option

Captive Screw
MLO-012260

>>> T SCSI
>>> T 10
•

If you are using a MicroVAX 3100 Model 90 or VAX 4000 Model 100
system, enter the following command at the console prompt to test the
operation of the RRD43 option:

>>> T E0
A successful pass of the test is indicated when the console displays the console
prompt.
If the test fails, the LED display on the back of the system unit displays a code
in the range A0 to A5 (hexadecimal), and the console terminal displays a hard
error message containing the test number (10) and the test mnemonic (SCSI).
The following is an example of an error printout.

?? 001 10 SCSI 0050
See your system maintenance manual for more information about the
diagnostics.
