Peel-off label covering Modified Modular Jack (MMJ) Ports 0 and 1. These
are the ports to which you can connect a user terminal, printer or other
device that uses asynchronous DEC423 data-line-only ports.
MMJ port 3; the only console port.

Asynchronous Modem Control Port (Port 2)—This is the port at which you
can connect a modem, terminal, printer, or other devices that use EIA-232
ports to the system unit.

Halt Button—This button halts the operating system and returns the
system to console mode.

1–2 MicroVAX 3100 Model 90 Hardware

Break/Enable Switch and LED—When the break/enable switch is in the up
position, you can halt the system by pressing the break key on the console
terminal keyboard. When the break/enable switch is in the down position,
you must use the halt button to halt the system.
The LED indicates the position of the switch as follows:
On when the break/enable switch is in the up position.
Off when the break/enable switch is in the down position.

Diagnostic LEDs—The diagnostic LEDs (status LED display) indicate
system and test status, and error conditions.

Standard Ethernet Port—This is the port to which standard Ethernet
connects to the system unit.

Network Select Switch—This switch selects either ThinWire™ or standard
Ethernet connection.
The system uses standard Ethernet when the network select switch is in
the left position. The system uses ThinWire Ethernet when the network
select switch is in the right position.

ThinWire Ethernet Port—This is the port to which ThinWire Ethernet
connects to the system unit.
System ac Power Cable and Port—This is the port through which ac power
from the power source reaches the system unit.
On/Off Switch—This switch turns the system unit on or off. To turn the
system on, set the on/off switch to the on ( | ) position. To turn the system
off, set the on/off switch to the off (O) position.
SCSI Ports—These are the ports to which external small computer system
interface (SCSI) storage devices connect to the system unit. A SCSI
terminator is installed in these ports during shipment. A single SCSI port
is standard in the MicroVAX 3100 Model 90 system, the second (upper)
port is optional.

1.2 Terminal Settings

DHW42-AA—This asynchronous option provides eight asynchronous
DEC423 data-line-only communications lines through one system port.
You can connect up to eight peripherals using the MMJ ports on the
harmonica (H3104) that connects to the option cable (BC16C-10).

–

DHW42-BA—This option is the same as the DHW42-AA, but provides
16 asynchronous DEC423 data-line-only communications lines through
two system ports. You can connect up to 16 peripherals using the MMJ
ports on two harmonicas (H3104) that connect to the option cables
(BC16C-10).

Use the following cables instead of the BC16C-10 cable if you require
longer than 10-foot cable lengths: BC16C-25 (25-foot), BC16C-50 (50-foot),
BC16C-A0 (100-foot), or BC16C-B5 (250-foot). Use the following cables
between the harmonica (H3104) and the DEC423 peripheral: BC16E-10,
BC16E-25, or BC16E-50.
–

DHW42-CA—This asynchronous option provides eight asynchronous
EIA-232 modem control lines through two system ports using two
breakout cables (BC29J-06).

–

DHW42-UP—This upgrade option converts a DHW42-AA asynchronous
option to a DHW42-BA option.

4–4 Hardware Options

Attach one of the following cables to a connector on the breakout cable if
you require longer cable lengths: BC22F-10, BC22F-25, or BC22F-50. The
peripheral you are using may require a null-modem extension cable. See
the peripheral documentation or contact your Digital Sales representative
for information on the correct null-modem cable to use.

4.3 Connecting a SCSI Expansion Box
The following subsections contain information on:
•

Guidelines for connecting expansion boxes

•

Selecting available SCSI IDs on the system

•

Setting the SCSI ID of devices in the expansion box

•

Preparing the system unit for an expansion box

•

Connecting the SCSI cable

•

Checking the expansion box connections

4–6 Hardware Options

4.3.1 Guidelines for Connecting Expansion Boxes
Use the following guidelines when connecting expansion boxes:
•

In the standard system, you can connect two SCSI devices in an expansion
box (in addition to connecting five devices internally).
If the KZDDA controller is installed, you can connect up to seven SCSI
devices on the second SCSI bus.

•

The maximum length of the SCSI cables must not exceed 6 meters (19.6
feet). This maximum length includes a maximum of 2 meters inside
the system unit and a maximum of 4 meters outside the system unit.
Therefore the external SCSI cable length, including the length of the SCSI
cables that are inside the expansion boxes, must not exceed 4 meters (13.1
feet).

•

Each device connected to a SCSI bus must have a unique SCSI ID.

•

Terminate the SCSI bus as described in the expansion box documentation.

•

Plug the expansion boxes into the same grounded power strip or electrical
circuit as the system unit.

•

Do not connect more than two tape drive devices.
Caution
Some expansion boxes are restricted to either 110 V ac or 220
V ac operation. Make sure that the voltage requirement of the
expansion box used is compatible with the supply voltage.
Turn on the expansion boxes before you turn on the system
unit. This procedure ensures that the device in each expansion
box is ready for use and that the system firmware includes the
device in the configuration display.
Do not connect or disconnect SCSI expansion boxes while
the system is turned on. Doing so can cause damage to the
equipment or corrupt data.
Digital cannot guarantee the correct operation of any SCSI
bus that uses cable assemblies not supplied by Digital or not
configured in accordance with these guidelines.

Hardware Options 4–7

4.3.2 Selecting Available SCSI IDs on the System
You must identify which SCSI IDs are available before connecting an expansion
box. Use the configuration display to determine this information. To see the
configuration display, enter the following command:

Removable Storage Media
This appendix contains information on the use and storage of the following
media types that are used by the optional removable media storage devices:
•

Tape cartridges

•

QIC tapes

•

Cassette tapes (DAT)

•

Diskettes

•

Compact discs

B.1 Tape Cartridges
The CompacTape cartridge (see Figure B–1) is a 10 cm by 10 cm (4 in by 4 in)
plastic tape cartridge that can be used by TZ30 tape drives. The TZ30 tape
drive is supplied with a CompacTape cartridge.
The CompacTape II is the successor to the CompacTape cartridge. The
CompacTape II supports higher recording densities because it has tighter
tolerances than the CompacTape. The CompacTape and the CompacTape II
(when used with TZ30 tape drive) have a capacity of 95M bytes. The TZ30
tape drive does not support CompacTape III cartridges.
Tapes that were originally written by a different type of tape drive may not be
compatible with the TZ30 tape drive. If the tape is not compatible, the TZ30
automatically unloads the tape cartridge and the green LED flashes to indicate
a tape error. Table B–1 shows the compatibility of the tape cartridges with the
TZ30 tape drive.

B.1.1 Labeling a Tape Cartridge
Always label tape cartridges. There is a slot for the label on the front of the
cartridge. The label is visible when the cartridge is in the drive. Labels or
markings on any other part of the cartridge can interfere with the proper
operation of the drive. Do not write on the cartridge with a pen, pencil, or
other marking instrument.
The labels supplied with the CompacTape II cartridges have spaces that mark
the capacity of the tape cartridge. Mark the 95M-byte block on the label when
using the TZ30 to write data to the tape cartridge.

B–2 Removable Storage Media

RE_EN06138A_91

B.1.2 Writing to and Write-Protecting Tape Cartridges
CompacTape and CompacTape II cartridges have a write-protect switch that
prevents an accidental overwrite of data. The system can read information on
the tape regardless of the position of the write-protect switch. However, the
system cannot write data to a write-protected tape.
Write-Protecting a Tape
When you use a tape to install software, set the write-protect switch on the
front of the cartridge to the write-protect position.
To write-protect a tape, set the write-protect switch to the write-protect position
by sliding it left towards the label until it locks in place (see Figure B–2). An
orange rectangle appears when the write-protect switch locks in the writeprotect position.
Writing to a Tape
When you use a tape to make a backup copy or to write data, set the writeprotect switch to the write-enable position. To set the switch to the writeenable position, slide it to the right, away from the label, until the switch locks
in place.

Removable Storage Media B–3

B.1.3 Handling and Storing Tape Cartridges
Inside the cartridge, a 600-foot single reel of magnetic tape stores data.
A plastic tape leader is at the beginning of the tape. Take the following
precautions when handling and storing tapes:
•

Do not touch the exposed surface of the tape.

•

Do not drop the tape cartridge.

•

Allow tape cartridges to reach room temperature before using them.

•
