4.3.1 Guideiines for Connecting Expansion Boxes
Use the following guidelines when connecting expansion boxes:
¢

You can connect up to two expansion boxes (SZ12-series expansion boxes
can contain two devices).

The recommended maximum length of the SCSI cables (internal length
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 electrical
circuit.

Do not connect more than twe 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 ¢ 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.

Digtal 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.

B.1 Tape Cartridges
The CompacTape cartridge (see Figure B-1) is a 10 ¢cm by 10 em (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 Il 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 TK50 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,
indicating a tape error.

. 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. 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 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.

B8.1.3 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 itemperature before using them.
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%.

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) positicn 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.

1.2.1 Power-Up Tests
The system runs the power-up tests each time you turn on the system. If the
system passes the tests, it responds with a display similar to the following:

kaa5-a vi.0@

08-00-2B-1A-0B-BB @

>>> @

Central Processing Unit (CPU) Name (KA45) and Firmware Version
Number (V1.0).

Ethernet Hardware Address.
Memory Size.

Status Bar—The completion mark ( | ) indicates the full extent of the
stitus bar. When the status bar reaches the completion mark, the powerup test is complete. On some terminals, the status bars are displayed as a
line of number signs (#).

Console Prompt!.

The system may not display the console prompt if the default recovery action is set
to boot or restart. See the

MicroVAX 3100 Model 30 Customer Technical Information

manual for more information on system defaults.

Error Type—Two question marks (??) indicaie a hard errcr, that is, a

fatal error that prevents the system from booting. One question mark (?)
indicates a soft error, that is, a nonfatal error that does not prevent the
system from booting.
Field Replaceable Unit (FRU).
Device Number.

Device Mnemonic.
Error Message.

Completion Mark—The completion mark ( | ) indicates the full extent of
the status bar when the power-up test is successful.
In this display, one question mark (?) indicates a soft error, whereas two
question marks (??) indicate a hard error.

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 s: stem from
successfully booting. If you encounter a hard error, see Section 1.2.2.

1-10

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.

1f you encounter a hard error in the power-up test display, follow these steps:

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 described 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:

>>> TBST NI

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

>>>

TEST 9

OK
>>>

2.1 Returning to Console Mode

To use the procedures described in this chapter, the system must be in console
mod=. Before returning to console mode, you must shut down the operating
system software if it is running. See the operating system documentation for
information on the shutdown procedures. To return to console mode, follow
these steps:

Shut down the operating system software if it is running.

Press the halt button on the back of the system unit. The system responds
with the console prompt (>>>) when it is in console mode.

Console Security Feature and System Detaults

. 2.2 Using the Alternative Console Port

The MicroVAX 3100 systems provide an alternative console port through MMdJ
port 2. You can use this alternative console port in the same way as you would
use the standard console port, MMdJ 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:
1.

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 you set the switch to the up position.
Set the on/off switch on the system unit to the on ( | ) position.

The system recognizes the position of the switch only when you set the
power switch to the on ( | ) position.

2.3 Console Security Feature
The console security feature allows you to disable most of the system console
commands. When the security password is set, there are two types of u<ers:
privileged users and unprivileged users. Privileged users know the security
password and can use the full range of console comuuands; unprivileged users
can use only the following commands:
¢

BOOT—Use this comman¢d without parameters to boot the operating
system.

CONTINUE—Use this command to return to the operating system after
pressing the halt button.

Chapter 3 describes the console commands.
The following subsections describe how to do the following:

2-4

Set the security password

Enable the console security feature

Change the security password

Disable the security password

Exit from privileged console mode

Console Security Feature and System Defaults

. 2.3.1 Setting the Security Password

The console security feature is disabled when you receive the system. To set
the security password on the system, follow these steps:
1.

Enter the following command at the console prompt (>>>):
>>> SET PSWD

The system responds with the following prompt:
PSWDL >>>

Note

The security password must be a string of exactly 16
hexadecimal characters (0 to 9 and A to F).

Write down the security password and store it in a safe place.
If you forget the security password, you must call your Digital
Services representative to disable the console security feature.

Enter a security password and press Return.
The system does not display the security password as you type it. The

system responds with the following prompt:
PSWD2 >>>

Verify the security password by entering it 2 second time.
The system does not display the security password as you type it. If you

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 consele 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 zll the console commands, give the command
format, and describe the significance of each parameter.

. 3.1 BOOT

Passes control to the virtual machine bootstrap (VMB) program, which resides

on the system ROM. The format of this command is as follows:
B[OOT] [1R5:]<bflg>] <ddau>(:]]
where:

R5: 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 boot device name i1s ESAQ; SCSI boot device names
have the following format:
ddcull

where:
-

dd is the device mnemonic

=~ c is the controller destination (always A)

Console Commands

3-~1

u is the SCSI ID value of the boot device

—

Il 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 thie command format. You can specify 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 program passes
a descriptor for device ESAO to the VMB program. This triggers the VMB
program to boot the system over the network.

3.2 CONTINUE

Allows you to exit from console mode and enter (or 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 as follows:
DIEPOSIT] [{/B | /W I /L 1 /Q 1 /A}] L/P i Vi /d}] [/G] (/U] [/N:<n>]
[{<addr> | <sym> | + 1 -] * | @} [<cdatum>]]

where:

3-2

/B/W/L/Q/A/P/V I |G/U/N<n>are deposit command qualifiers
(see Table 3-1).

Console Commands

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

the size and address qualifier of the previous memory-specific command. If
you specify conflicting qualifiers, the console program ignores the command
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 3FFF.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.

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

deposit data (see Table 3-2).
®

4+ - *@ are operators that you can use for relative memory addressing (see
Table 3-3).

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