Laser
• Typ: Halbleiterlaser GaAlAs
• Wellenlänge: 780 nm
• Ausgangsleistung: 0,6 mW
• Strahldivergenz: 53,4°±1,5°

ZU IHRER SICHERHEIT
Vorsicht
Um Feuergefahr und die Gefahr eines elektrischen Schlages zu vermeiden,
darf das Gerät weder Regen noch Feuchtigkeit ausgesetzt werden.
Um einen elektrischen Schlag zu vermeiden, darf das Gehäuse nicht geöffnet
werden. Überlassen Sie Wartungsarbeiten stets nur einem Fachmann.
Überlassen Sie Wartungsarbeiten dem von Sony zugelassenen Fachmann.
Achtung
Da der interne Laserstrahl in lhre Augen eindringen und Verletzugen
verursachen kann, darf das Gehäuse nicht selbst geöffnet werden. Überlassen
Sie Wartungsarbeiten stets nur einem Fachmann.
Die Verwendung von Brillen, Kontaktlinsen usw. vergrößert die Gefahr.
Zur besonderen Beachtung
Zur Sicherheit
Sollte ein fester Gegenstand oder Flüssigkeit in das Geräteinnere gelangen,
trennen Sie das Gerät von der Wandsteckdose ab und lassen Sie es von einem
Fachmann überprüfen, bevor Sie es weiter verwenden.
Zum Abziehen des Kabels fassen Sie stets am Stecker und niemals am Kabel
selbst an.
Zur Aufstellung
Stellen Sie das Gerät weder auf einer weichen Unterlage (z.B. Decke,
Teppich) noch in der Nähe von Vorhängen, Tapeten usw. auf, da hierdurch
die Ventilationsöffnungen blockiert werden können.
Zur Reiningung
Verwenden Sie zur Reinigung des Gehäuses, des Bedienungspultes und der
Bedienungselemente ein trockenes, weiches Tuch oder ein weiches, leicht
mit mildem Haushaltsreiniger angefeuchtetes Tuch. Lösemittel wie Alkohol
oder Benzin dürfen nicht verwendet werden, da diese die Gehäuseoberfläche
angreifen.

1 RRD42DiscDrive ProductDescription
Overview
Description The RRD42 disc drive is a half-height, 5¼-inch, 600-megabyte,
compact disc, storage device compatible with Digital systems.
The drive, capable of audio playback, has audio line outputs
and a headphone jack.
NOTE
The audio capability is included in the hardware and is
operating system dependent. Operating system support
will be added when it becomes available.
The device uses the SCSI-2 (small computer system
interconnect) bus, and can be used on low-end, desktop, and
Digital workstation systems.
Two Drive
Versions The RRD42 drive is the primary load device for operating
system software and layered products. Two versions of the
drive are available: the tabletop version and the embedded
version. Although the installation of the drives differ, they
function the same. Figure 1–1 shows the RRD42 front panel.
1–1

1–2 RRD42 Disc Drive Product Description
Tabletop Drive The RRD42 tabletop drive is a standalone unit and contains
industry-standard SCSI connectors on the rear panel. An
address selection switch, 3-pin ac connector, and audio output
jacks are also on the rear panel.
Embedded Drive The RRD42 embedded drive is designed to be installed in a host
system. The embedded drive can be used in a horizontal or
vertical position.

2 Generic Installation
Familiarizing Yourself with the Drive
In this Chapter This chapter describes:
• Becoming familiar with the drive
• Connecting the cables
• Installing the RRD42 tabletop drive
• Installing the RRD42 embedded drive
• Setting the SCSI ID address
• Verifying installation with power-on self-test (POST)
This chapter provides general installation procedures. This
chapter does not give specific, host system installation
instructions.
Part Locations To familiarize yourself with the tabletop and embedded drives’
buttons, switches, and connectors, see Figure 2–1. The tabletop
and embedded drives have the same front panel.
See Figure 2–2 for a rear view of the RRD42 tabletop drive and
Figure 2–3 for a rear view of the RRD42 embedded drive.

2–4 Generic Installation
Mode Select
Jumper IMPORTANT
The mode select jumper is a USER-SELECTABLE feature
for the embedded drive only. If you do not select the
correct mode, the drive does not operate properly.
The mode select jumper has two modes:
Mode 0 — Jumper Out. In this mode the drive block size
is 2 kilobytes. Use Mode 0 under MS–DOS and SCO UNIX
operating systems.
Mode 1 — Jumper In. When the jumper is installed, the
drive operates with a block size of 512 bytes. Use Mode 1
under VMS and ULTRIX operating systems.
The mode select jumper does not affect other operations.
NOTE
The microcode revision reported by the RRD42 disc
drive depends on the mode selected.

Connecting the Cables
Connecting
Tabletop Drive to
System
WARNING
To prevent fire or shock hazard, do not expose the unit
to rain or moisture.
To avoid electrical shock, do not open the cabinet. Refer
servicing to qualified personnel only.
If you are connecting an RRD42 tabletop drive directly
to your system, use the SCSI signal cable supplied in
your system installation kit..
If you do not have this cable, contact your Digital sales
representative. Use a cable supplied by Digital Equipment
Corporation. Failure to do so may result in degraded
performance of your RRD42 drive.
To connect a SCSI cable — drive to system — perform the
following steps:
1. See Figure 2–4.
2. Connect one end of the cable to the host system SCSI port.
3. Connect the other end of the SCSI signal cable to the top
SCSI connector on the rear of the RRD42 drive.
4. Snap the wire cable clamps into place to secure the SCSI
cable.
5. Connect the SCSI terminator to the bottom SCSI connector
on the rear of the RRD42 drive, if this device is to be the
last unit on the bus.
6. Snap the wire cable clamps into place to secure the
terminator.
