Setting the Jumpers

Setting the Jumpers
SCSI Address
Settings

For proper communication between your system and all the
drives installed in the system unit, each drive must have a
unique SCSI address setting. These settings are determined
by the position of three removable electrical connectors, called
jumpers, located on the back of the drive. On the RRD42 drive,
these jumpers are labeled 0, 1, and 2 and can be either attached
or removed.

Operating
System Setting

The RRD42 drive also includes a mode jumper. Be sure this
jumper is attached to ensure that the drive works with the
operating system.

SCSI Factory
Setting

When your RRD42 drive arrives from the factory, all SCSI
jumpers may be attached to prevent their loss during
shipment. If this is the case, you should reset the jumpers
to the recommended SCSI address setting of 4, as shown in
Figure 3–2, where:
•

Jumper 0 is removed

•

Jumper 1 is removed

•

Jumper 2 is attached

Setting the SCSI Switches
Types of
Switches

The SCSI-FDI
Switch

There are two types of SCSI switches you must set for the RX26
diskette drive:
•

The SCSI-FDI (floppy disk interface) switch that interfaces
with the SCSI-FDI controller.

•

The SCSI address switch.

The RX26 drive is one of three types of diskette drives. Each
diskette drive is connected to a SCSI-FDI controller through a
SCSI bus.
For the SCSI-FDI controller to recognize the different drives,
there is a different select number (0, 1, and 2) for each drive.
For the RX26 drive, be sure the select number is in position 2
by moving the slide switch, shown in Figure 4–2, to the forward
position.

4–3

Setting the SCSI Switches

Figure 4–2 RX26 SCSI-FDI Switch

MLO-007561

SCSI Address
Settings

For proper communication between your system and all the
drives installed in the system unit, each drive must have a
unique SCSI address setting. SCSI settings are determined by
the position of the electrical switches located on the side of the
drive. These switches can be either up or down.

SCSI Factory
Setting

When your RX26 drive arrives from the factory, it should
be preset to the recommended SCSI setting 5, as shown in
Figure 4–3, where:
•

Switch 1 is down

•

Switch 2 is up

•

Switch 3 is down

However, if the drive is not preset to setting 5, you need to
change it only if that drive’s preset setting is already taken by
another device installed in your system.

Setting the Jumpers

Setting the Jumpers
SCSI Address
Settings

For proper communication between your system and all the
drives installed in the system unit, each drive must have a
unique SCSI address setting. These settings are determined
by the position of three removable electrical connectors, called
DADS and DRIVE SELECT jumpers, located on the back of the
drive. These jumpers can be either attached or removed.

Operating
System Setting

The TZK10 drive also includes a DADS (parity) jumper, shown
in Figure 5–2 as the sixth jumper from the left. Be sure this
jumper is attached to ensure that the drive works with the
operating system.
The DRIVE SELECT jumpers allow selection of a unique address
for each drive. These jumpers are the second, third, and fourth
jumpers from the right side.

SCSI Factory
Setting

5–4

When your TZK10 drive arrives from the factory, all SCSI
jumpers may be attached to prevent their loss during
shipment. If this is the case, you should reset the jumpers
to the recommended SCSI address setting of 5, as shown in
Figure 5–2, where, counting from the left:
•

The seventh jumper is attached

•

The eight jumper is removed

•

The ninth jumper is attached

Using Cartridge Tapes
Guidelines for
Handling and
Storing

When handling and storing TZK10 cartridge tapes:
•

Do not drop or strike tapes.

•

Keep tapes out of direct sunlight, away from heaters and
other sources of heat.

•

Store tapes where the temperature is between 10°C and 40°C
(50°F and 104°F).

•

If a tape has been exposed to extreme heat or cold, allow it
to stabilize at room temperature for the same amount of time
as it was exposed, up to 24 hours.

•

Avoid placing tapes near sources of electromagnetic
interference, such as terminals, motors, and video or Xray equipment. Any tape exposed to a magnetic field can lose
information.

•

Store a tape in a dust-free environment where the relative
humidity is between 20% and 80%.

•

Store a tape in its protective container, on edge or stacked.
However, when stacking tapes, do not stack more than five
high.

Setting the SCSI Switches

Setting the SCSI Switches
SCSI Address
Settings

For proper communication between your system and all the
drives installed in the system unit, each drive must have a
unique SCSI address setting. These settings are determined by
the position of the electrical switches located on the back of the
drive. On the TLZ06 drive, the relevant switches are labeled 1,
2, and 3 and can be either up or down.

Operating
System Setting

The TLZ06 drive also includes a mode switch. Be sure this
switch is in the down position to ensure that the drive works
with the operating system.

SCSI Factory
Setting

When your TLZ06 drive arrives from the factory, it should be
preset to the recommended SCSI setting of 5, where:
•

Switch 1 is down

•

Switch 2 is up

•

Switch 3 is down

•

Switch 4 is up

•

Switch 5 (mode) is down

However, if the drive is not preset to setting 5, you need to
change it only if that drive’s preset setting is already taken by
another device installed in your system.
Figure 6–2 shows the possible settings of the TLZ06 drive.

Using Cassette Tapes
Guidelines for
Handling and
Storing

When handling and storing TLZ06 cassette tapes:
•

Do not drop or strike cassettes.

•

Keep cassettes out of direct sunlight, away from heaters and
other sources of heat.

•

Store cassettes where the temperature is between 5°C
and 32°C (40°F and 90°F). If a cassette has been exposed
to extreme heat or cold, allow it to stabilize at room
temperature for the same amount of time as it was exposed,
up to 24 hours.

•

Avoid placing cassettes near sources of electromagnetic
interference, such as terminals, motors, and video or X-ray
equipment. Any tape exposed to a magnetic field can lose
information.

•

Store a cassette in a dust-free environment where the
relative humidity is between 20% and 60%.

6–11

Using Cassette Tapes

Task Overview:
Using TLZ06
Tapes

•

Store a cassette in its protective container, on edge or
stacked. However, when stacking cassettes, do not stack
more than five high.

•

Periodically clean the drive heads. (See the next section.)

These are the tasks you may want to perform with a TLZ06
cassette tape:
Task

Action

Clean the drive heads

Label the tape

Write-protect the tape

Insert the tape into the drive

Remove the tape from the drive

The following sections describe these steps.

Task 1: Clean
the Tape Drive
Heads

Statistics show that over 90 percent of tape drive-related
problems are associated with the tapes. Therefore, Digital
recommends that you clean the drive heads about every two
weeks or after every 25 hours of use.
To clean the heads, follow these steps:
1. Turn the system On/Off switch to the on ( | ) position.
2. Make sure the busy indicator light is on.
3. Insert the head-cleaning cassette that came with your tape
drive into the drive.
4. The drive automatically begins cleaning the heads, and ejects
the cassette after about 30 seconds.
5. In the space provided on the head-cleaning cassette, place a
check mark every time you use the tape.
Under normal conditions, each head-cleaning cassette is good
for approximately 25 cleanings. See your Digital service
representative to order additional cassettes.

RZ24L Fixed Disk Drive Description

RZ24L Fixed Disk Drive Description
Purpose

The RZ24L disk drive allows you to store large amounts of data
on a fixed disk. The drive can be used for storage of software
applications and user files.

Setting the SCSI Jumpers

Setting the SCSI Jumpers
SCSI Address
Settings

For proper communication between your system and all the
drives installed in the system unit, each drive must have a
unique SCSI setting. SCSI settings are determined by the
position of three removable electrical connectors, called jumpers,
located on the back of the drive. On the RZ24L drive, these
jumpers are labeled A0, A1, and A2 and can be either attached
or removed.

SCSI Factory
Setting

When your RZ24L drive arrives from the factory, all SCSI
jumpers may be attached to prevent their loss during shipment.
If this is the case, you should reset the jumpers to an address
setting of 1, 2, or 3, the recommended settings for a fixed disk
drive. Figure 8–2 shows the disk set at SCSI setting 2, where:
•

Jumper A0 is removed

•

Jumper A1 is attached

•

Jumper A2 is removed

However, if the drive is not preset to one of those settings, you
need to change it only if that drive’s preset setting is already
taken by another device installed in your system.

Removing a TURBOchannel Option Module

Although this chapter covers TURBOchannel option modules
manufactured by Digital, other companies have developed
modules that may be compatible with the DEC 3000 Model
400/400S AXP system. Digital’s TRI/ADD program works with
these third-party manufacturers to ensure compatibility with
the TURBOchannel specification. Consult your Digital sales
representative for more information.

TURBOchannel Description
Definition

A TURBOchannel is a high-performance interconnection that
allows you to use a variety of Digital and third-party graphics,
multimedia, and communications options. The TURBOchannel
has a synchronous asymmetrical I/O channel that connects
option modules to the system module. The system module and
an option module have read or write access to each other, but
option modules have no access to other option modules.

TURBOchannel
Module Widths

TURBOchannel option modules come in three different widths:
single-, double-, or triple-width. The modules connect to
connectors on the system unit. There are also two upgrade
kits that connect directly to the PXG module: the 8-to-24 plane
upgrade and the 24-bit Z buffer upgrade.

12–2

Graphics Support

Graphics Support
Graphics support is dependent on which operating system you
are running, as shown in the next two sections.

OpenVMS
Alpha Graphics

If your system is running the OpenVMS AXP operating system,
