Installing the RRD42 Tabletop Drive
Introduction
If you are installing an RRD42 drive on a running system,
have your system manager perform an orderly shutdown of
the operating system: stop and power down the system and all
attached SCSI devices.
SCSI Cable
Requirements
Up to seven SCSI devices can be connected through a SCSI bus
in a daisy chain. The total length of the SCSI cables (including
internal cables in attached expansion boxes) should not exceed
6 meters (19.67 feet).
On Digital systems using the KZQSA SCSI to Q–bus adapter,
the length of the external SCSI cable cannot exceed 2 meters
(6.56 feet). The cables used with the KZQSA must be option
number BC06P or part numbers: 17-02659-01, 0.30 meters (1
foot); 17-02659-02, 1.82 meters (6 feet); and 17-02659-03, 0.76
meters (2.5 feet)
The KZQSA adapter can support only a maximum of two
devices on each port.
Assigning the
SCSI ID
•
Assign the SCSI bus ID number for each drive using the ID
SELECT switch on the rear (Figure 2–2).
•
Do not use the same ID number as the one already set for
the other SCSI device on the same bus.
2–12 Generic Installation
Installing the RRD42 Embedded Drive
Introduction
The installation of the embedded drive varies with different
host systems. Consult your host system installation guide for
correct mounting directions.
NOTE
The embedded drive is shipped with a plastic cover
to prevent dust infiltration. DO NOT REMOVE THIS
COVER. Take care when installing the cables in the rear
of the embedded drive. Make sure the dust cover does
not interfere with the SCSI cable connector.
The RRD42 does not require periodic cleaning. However,
the environment where the drive is installed should be
clean.
Setting the SCSI
ID
A set of pins with jumpers installed on the rear panel of the
embedded drive must be set to correspond to the configuration
of your computer system (Figure 2–3). Remove and install
jumpers as necessary, using small pliers or tweezers.
Mode Select
Jumper
IMPORTANT
The mode select jumper is a USER-SELECTABLE feature.
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.
Generic Installation 2–13
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.
Jumpers 0–2
Assign the embedded drive’s ID number by setting the ID
SELECT jumpers in or out. Do not assign the same number
used on another SCSI device.

Changing the
SCSI ID Jumper
Setting
If either of the following conditions exist, change the SCSI ID
jumper setting:
•
If you install the RRD42 drive on a system that already has
a SCSI device attached, use any available SCSI ID. (You
may need to consult your system manager for available
SCSI IDs.)
•
If you install multiple RRD42 (or other SCSI) drives, make
sure the SCSI ID for each drive is set with the drive’s
unique SCSI ID. No two drives in the series can have
identical SCSI IDs.
If you need to change the SCSI ID, select the desired SCSI ID
from Table 2–1.
Verifying the RRD42 Drive Installation
Executing POST
To verify successful installation of the RRD42 drive by
executing power-on self-test (POST), perform the following
steps:
1. Power on the drive.
2. Load a disc with the caddy into the drive.
3. The BUSY indicator lights for about 10 seconds and then
extinguishes.
4. Continue the procedure: power up the remaining external
devices, and then power up the host systems.
5. Run one pass of the host system or MicroVAX diagnostic
monitor (MDM) diagnostics to verify system operation.

drive, and insert the caddy into the caddy insertion slot
(Figure 3–6).
The drive reads the Table of Contents (TOC) on the disc.
The BUSY indicator lights while the TOC is read.
2. When the BUSY indicator goes off, the drive is ready to
receive the command from the host computer.
3. Follow the instructions provided by the host system’s
software manual.
