lever to the lock position. Then move the operate lever to the unlock

position and reinsert the tape cartridge.

Do not push the tape cartridge into the TZ30 while moving the operate
lever between the lock and unlock positions. If you do so, the TZ30
interprets this action as an insertion of the tape cartndge.

The green LED turns on.

Move the operate lever to the lock position to lock the tape cartridge in the
drive.

The green LED turns off, and the yellow LED starts to flash, indicating

that the tape is loading. When you load the tape and it is ready for use,
the yellow LED stays on. When the yellow LED stays on and the green
LED stays off, the tape is ready to use.

You can connect up to two expansion boxes (SZ12-series expansion boxes

The recommended maximum length of the SCSI cables (internal length

can contain two devices).

plus external length) is 19.6 feet (6 metres).

Each device in the expansion boxes must have a unique SCSI ID.

You must attach the 50-pin terminator that comes with the expansion box
to an unused SCSI connector on the back of an expansion box.

Plug the expansion boxes into the same grounded power strip or elecirica
circuit.

Do not connect more than two tape drive devices.

—

Cawtion __

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.

Diskettes

Compact discs

B.1 Tape Cartridges
The CompacTape cartridge (see Figure B—1) is a 10 em by 10 cm (4 inches by
4 inches) plastic tape cartridge that can be used by TZ30 or TK50 tape drives.
The TZ30 tape drive is supplied with a CompacTape.

The CompacTape II is the successor to the CompacTape cartridge. The
CompacTape II has tighter tolerances than the CompacTape, which support
the higher recording densities of the TK70. The CompacTape and the
CompacTape Il (when used with TZ30 and TK5C tape drives) have a capacity
of 95M bytes.
The TZ30 can use a CompacTape or CompacTape Il cartridge that was

originally written by the TK50. If a CompacTape II cartridge written by a
TK70 is used on a TZ30, the TZ30 automatically unloads the tape cartridge,
because the TZ30 cannot read the tape cartridge. The green LED flashes.

. 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 snaces that mark
the capacity of the tape cartridge. If a TK50 or TZ30 wrote data to the tape
cartridge, mark the 95M-byte block on the label. If a TK70 wrote data to the
tape cartridge, mark the 296M-byte block on the label.
If you use TK70 and Tz30 drives, note that the TZ30 is unable to read or write
tapes that have originally been written to by the TK70. However, the TK70
can read tapes written by the TZ30 or the TK50.

B.1.2 Writing to and Write-Protecting Tape Cartridges

CompacTape and CompacTape 1I 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.

B.1.3 Handiing 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 car...dge.

Allow tape cartridges to reach room temperature before using them.

Store the tape wheve the room temperature is between 10°C and 40°C

(50°F and 104°F) and the humidity is between 20% and 80%.

B-4

Place the identification label in the slot provided on the tape cartridge.

Store the tape cartridge ii: its plastic cover.

Do not expose the tape to direct sunlight, heat, magnetic fields, or X-rays.

. B.2.1 Guidelines for Using QIC Tapes

Use the following guidelines when using QIC tapes:
*

Do not drop the tape.

Store the tape where the room temperature is between 10°C and 40°C
(50°F and 104°F) and the humidity is between 20% and 80%.

Do not expose the tape to direct sunlight, abrasive particles, or
electromagnetic fields.

Store the QIC tape in its protective container, placed on its edge, or
stacked. Do not stack QIC tapes more than five high.

Place the identification label in the space provided on the top of the QIC
tape.

Removable Storage Media

B-7

B.2.2 Setting the QIC Tape Write-Protect Switch

There is a write-protect switch on one corner of the QIC tape. This switch
allows you to write-protect the data on the tape. After writing data to the QIC
tape, write-protect the tape to prevent accidental erasure or overwriting of that
data. Use the write-protect switch as follows:
Turn the write-protect switch to the safe (write-protect) position when you
want to protect the data on the tape, or when you want to read or copy
data from the tape.
Turn the write-protect switch to the write-enable position when you want
to write data to the tape.

’ B.3 Diskettes

Diskettes are magnetic disks that store information. Digital recommends that
you use either high-density (HD) or extra-density (ED) diskettes. ED diskettes
have a capacity of 2.88M hytes and HD diskettes have a capacity of 1.44M
bytes.

Keep the diskettes dry, out of extreme temperatures and direct sunlight, and
away from devices that contain magnets, such as telephones.

B.3.1 Writing to and Write-Protecting Diskettes
Write-protecting a diskette prevents accidental erasure of information. The
RX26 diskette drive can read information on the diskette regardless of the
position of the write-protect switch. However, the system cannot write data to
a write-protected diskette.

Removable Storage Media

B-9

Write-Protecting a Diskette

When you use a diskette to install application software on the system or to
protect information on the diskette, set the write-protect switch on the back of
the diskette to the write-protect position by moving the switch down until it
locks in place (see Figure B—4).

Writing to a Diskette

When you use a diskette to make a backup copy of a file or to write data to
a diskette, set the write-protect switch to enable writing to the diskette. To
enable writing, set the switch to the write-enable position by moving it up,
until it locks in place.

Usually, you can ignore soft errors. Soft errors are often caused by temporary
problems, and the system can boot despite the error. Hard errors, however,
usually indicate a more serious problem that may prevent the system from
successfully beoting. If you encounter a hard error, see Section 1.2.2.

Troubleshooting and Diagnosing Problems

1.2.2 Self-Tests
Self-tests perform the same tests as the power-up tests except for one
difference; the power-up tests test all the devices in the system, whereas
the self-tests allow you to test a single device.
If you encounter a hard error in the power-up test display, follow these steps:
i.

Write down the number or mnemonic of the tests that failed.
In the examples in this section, device 9 (NI), the Ethernet device, has
a hard error associated with it. Table 1-2 lists the device numbers,
mnemonics, and names of the system devices.

Make sure that all the required cables and terminators are securely
connected to the proper ports by following the procedure de:cribed in
Section 1.1.

Run the self-test on each device that failed by entering a command similar
to the following:
>>> TBST 9

Alternatively, instead of the device number, you can enter the command

using the device mnemonic:
>>> TEST NI

If the self-test is successful, the system responds with the following display:

>>>

. 2.2 Usinj the Alternative Console Port

The MicroVAX 3100 systems provide an alternative console port through MMJ
port 3. You can use this alternative console port in the same way as you would
use the standard console port, MMJ port 0. However, the alternative console

port allows you to halt the system by pressing the break key on the keyboard,
a feature that is not available when you use the standard console port. To

enable the alternative console port, follow these steps:

Set the on/off switch on the system unit to the off (O) position.

Connect a terminal to MMJ port 3.

Set the break/enable switch to the up position.

The break enable LED lights when ycu set the switch to the up position.

Console Commands
This chapter describes the console commands that you can enter when the
system is in console mode. The system displays the console prompt (>>>) when
it is in console mode. If the system is running the operating system software,
see Chapter 2 for information on returning the system to console mode.
If the console security feature is enabled and a security password is set, you
must log in to privileged console mode before using most of these commands.

See Chapter 2 for information on the console security feature.
The following sections describe all the console commands, give the ccmmand
format, and describe the significance of each parameter.

® 1 eoor
Passes control to the virtual machine bootstrap (VMB) program, which resides
on the system ROM. The format of this command is as follows:

BIOOT] [/IR5:1<bfig>]) <drau>(:]]
where:
¢

RS represents a register, through which the hexadecimal value
represented by <bflg> is passed to the VMB.

<bflg> is the boot flag value.

<ddau> is the name of the boot device. It passes to the VMB in register

RO.

The Ethernet network hoot device name is ESAQ; SCSI boot device names
have the foliowing format:

ddcull
where:

dd is the device mnemonic

¢ 1s the controller destination (always A)

Console Commands

3-1

-y is the SCSI ID value of the boot device
—

1l is the logical unit number

The console program accepts device names in lowercase characters, but it
is recommended that you use uppercase characters. You can specify more
than one boot device, and you can type a colon at the end of the device
names as shown in the command format. You can specifv up to two devices
on the command line. You must separate device names by typing either a
space or a comma.

If the nonvolatile RAM (NVR) contains a default boot device name, the console
program passes the descriptor for this device to the VMB. The VMB then boots

the system from the specified device.
If you do not specify a device name or qualifiers or both in the command, the

system attempts to boot from the default boot device specified in the NVR. If
the default boot device is not defined ((NULL}), the console pregram passes
a descriptor for device ESAQ to the VMB program. This triggers the VMB
program to boot the system over the network.

3.2 CONTINUE
Allows you to exit from conscle mode and enter (cr reenter) program mode (the
operating system). The format of this command is as follows:

CIONTINUE]
The address to which control passes is one of the following:
*

The address stored in the program counter when the system went into

console mode
*

The address that the user specifies using the DEPOSIT command

3.3 DEPOSIT
Transfers the specified data to the specified address. The format of this
command is es follow.:

DIEPOSIT] [(/BI/W I /L 1/Q 1 /AY] [{P 1 /V i M}] [/G] [/U} [/N:<n>]
[{<addr> | <sym> | + | - | * | @) [<datum>]]

where:

/B/W/L/Q /A /P ]V /I |G /U /Nxn> are deposit command qualifiers

(see Table 3-1).

3-2

Console Commands

If you do not specify a size or address qualifier, the console program uses

the size and address qualifier of the previous memory-specific command. If
you specify conflicting qualifiers, the console program ignores the ccmmand
and generates an error message. The effects of the miscellaneous qualifiers
are not valid outside the command in which they are specified.
Note

The /U (unprotect) qualifier allows access to almost any address. If
you do not use the /U qualifier, you can access address locations in
the range 2000.0000 to SFFE.FFFF (excluding the TOY clock). The /U
qualifier is intended for use only by firmware developers.

<addr> is the hexadecimal address into which you want to deposit the

data.
°

<gym>is a mnemonic that represents the address into which you want to

deposit data (see Table 3-2).
®

+-*@ are operators that you can use for relative memory addressing (see

Table 3-3).
e

<datum> is the value you want to deposit in the address location you

specify.
