The only difference between the three models is the central
processing unit (CPU) module. The CPU in the Model 120
workstation operates at a speed of 20 megahertz (MHz), the
CPU in the Model 125 operates at a speed of 25 MHz, and the
the CPU in the Model 133 operates at a speed of 33 MHz.

1–2 Getting Started

In addition to the manual you are reading, you should have
Any options you ordered.
Any software you ordered.
All the items shown in Figure 1-2, on page 1-4, with one
exception. You should only have one type of video cable
assembly: color, monochrome, or gray-scale. However, you
may have more than one cable assembly of that type.
Save the cartons that your workstation is packed in. You may
need them later.

1–4 Getting Started

Workstation Site Requirements
For your workstation to function efficiently, your work
environment must meet the requirements listed here.
Caution: Failure to meet these requirements can damage equipment.

Temperature
Keep the temperature around the workstation between
50°F and 104°F (10°C and 40°C).
– Set up your workstation away from heaters,
photocopiers, and other sources of heat.
– Protect your workstation from direct sunlight.
Allow air to flow freely around your workstation to keep
heat from building up and damaging your equipment.
– Leave 4 inches (10 centimeters) of space between
system unit vents and other objects.
– Leave 3 inches (7.6 centimeters) of space between
monitor vents and other objects.
Humidity
Keep relative humidity within the range of 10 to 80 percent.
Cleanliness
Keep your work area as dust-free as possible.
Interference
Set up your workstation at least 30 inches (76.2
centimeters) away from other terminals or monitors
and from other sources of electrical interference, such
as printers or electric pencil sharpeners.
Limit exposure to static electricity and magnetized objects
by setting up your workstation away from busy corridors
and other high-traffic areas and away from filing cabinets
and steel beams in walls.

Getting Started

1–5

Power
The fuse for your outlet must be at least 15 amperes.
Be sure your electrical circuit is properly grounded. If
possible, use a surge-protected power strip to connect the
power cord to your workstation.
Be sure the voltage for workstation devices matches that of
your power source.
Supplies
Store supplies, such as tape cartridges, within the same
temperature and humidity limits as those for your
workstation.

1–6 Getting Started

Workstation Voltage Requirements
The voltage for many devices, including most monitors, must
match that of your power source. Your power source is either
110/120 or 220/240 volts. Where necessary, a yellow voltage
label that covers the power connector on your device tells you
the voltage requirements for that device.
Caution: Connecting a device to a power source that does not meet

the voltage requirements of that device can damage the device.

Attaching a SCSI Terminator to the Base System SCSI
Connector
A connector for a small computer system interface (SCSI) is
built into the base system hardware, as shown in Figure 2-1,
on page 2-2. When the connector is not connected to a SCSI
device (a disk drive or other device that uses a SCSI interface),
it must be terminated with a SCSI terminator. Otherwise, the
workstation may not function properly.
For the time being, put a SCSI terminator on the SCSI
connector on the system unit. You can remove the terminator
later if you connect SCSI devices to the system unit.
Your system unit may have additional SCSI connectors
in option slots. Do not attach SCSI terminators to these
connectors.

Supplying Power to the System Unit and Monitor
The system unit takes power from a power outlet, and the
monitor, in turn, takes power from the system unit. The
monitor connects to the system unit with a short cable.
Sometimes the workstation is supplied with an extra power
cord. In this case, you can also connect the monitor to a power
outlet. The power cord is longer than the monitor-to-systemunit power cable, allowing you to move the monitor away from
the system unit.

Ethernet Hardware for the Basic
Workstation
This chapter explains how to connect ThickWire Ethernet
loopback connectors to all ThickWire Ethernet connectors on
the system unit. Ethernet is a standard set of conventions or
rules for network communications. A network is a group of
computers and other communications devices that are linked
together.

Ethernet Hardware for the Basic Workstation 3–1

Installing ThickWire Ethernet Loopback Connectors
A ThickWire Ethernet connector is built into the base system
hardware, as shown in Figure 2-1, on page 2-2. If your
workstation is equipped with the TURBOchannel options,
you have additional ThickWire Ethernet connectors in the
TURBOchannel option slots. All of the connectors must be
either connected to an Ethernet cable or closed with a loopback
connector.
For the time being, put a loopback connector on every
ThickWire Ethernet connector on the system unit. You can
remove the loopback connectors later, when you connect
the workstation to your networks. See Chapter 6, section
‘‘Connecting the Workstation to a ThickWire Ethernet
Network’’, on page 6-3 for an explaination on how to connect to
a network.

Installing and Removing Memory
DECstation 5000 Model 100 Series workstations use pairs of
2-megabyte or 8-megabyte memory modules. Your workstation
can hold up to eight pairs of memory modules.
The system unit comes with at least four 2-megabyte MS01-AA
or MS01L-AA memory modules or two 8-megabyte MS01-CA
memory modules in place.
With pairs of 2-megabyte MS01-AA or MS01L-AA memory
modules, you can install up to 32 megabytes of memory.
With pairs of 8-megabyte MS01-CA memory modules, you
can install up to 128 megabytes of memory.
The cnfg command shows how much memory is installed
in your workstation. Chapter 11 explains how to use the
command.
To Install Memory Modules
Use either 2-megabyte or 8-megabyte memory modules in your
workstation. The MS01-AA and the MS01L-AA can be used
interchangably.
Caution: Do not mix 2-megabyte and 8-megabyte memory modules in
the same system. This will cause the 8-megabyte modules to act as
2-megabyte modules.

You need a medium Phillips screwdriver.

In expansion boxes that can be connected to the system
unit
To install hard disk drives in the base of the system unit,
turn to the section ‘‘To Install a Drive in the System Unit’’, on
page 5-28. Hard disk drives are drives in which the recording
media are disks fastened permanently inside the drive.
To install removable media drives in the front drive panel, turn
to the section ‘‘To Install a Removable Media Drive Inside the
System Unit’’, on page 5-42. Removable media drives are drives
where the recording media are disks and tapes that you can

Understanding SCSI ID Numbers
The workstation distinguishes each internal and external
drive connected to a small computer system interface (SCSI)
connector by the SCSI ID number (0 to 6) assigned to that
drive.
Each drive comes from the factory with a SCSI ID number
already set. These factory settings, called default settings, are
listed in Table 5-1.
Table 5-1. Default SCSI ID Numbers for Internal Drives
Drive

* If the system contains two RZ23L, RZ24, or RZ25 drives, the ID numbers
are preset to 2 and 3 at the factory.
Setting the SCSI ID numbers on your drives

Each drive within a group (or chain) of drives must have its
own unique SCSI ID number (0 to 6), in order to function
properly.
To avoid the problem of duplicate SCSI ID numbers within the
same group, don’t use more than one drive that has the same
default setting.
To check for duplicate SCSI ID numbers, you must examine the
settings on your drives, as shown in Appendix D of this guide.

number that is different from any SCSI ID numbers noted
in the DEV column of the display.
a. Read the device codes that you wrote down. In the
example, tz1. was written.
b. Choose any number from 0 to 6 that is not the same as
the numbers in the device codes. In the example, we
can choose 0, 2, 3, 4, 5, or 6, because the only number
in the device codes is 1. In this example, assume that
we chose 2.
c. Write down the new number on the same paper where
you wrote the device codes.
Use a pair of needle-nose pliers to set the SCSI ID on
the drive that you are installing. Set the ID to the new
number that you chose by arranging the SCSI switches
or jumpers to indicate the number. Jumpers are small
rectangular collars that fit over the ID pins on drives and
other components. If your drive uses jumpers, the jumpers
are already on the pins, and you have to arrange them
appropriately.
In Appendix D, Figures D-1 through D-7 show how to
arrange the jumpers on each hard disk drive. They also
show the connectors for the power supply and SCSI cables.

Write down any device codes that are displayed in the DEV
column on your screen. In this example, we would write
down rz2 and tz1.
Turn off the system unit by pressing 0 on the on/off switch
on the back of the unit.
Remove the cover from the system unit, as shown in
Figure 5-1, on page 5-3.
Place the loop of the antistatic strap around your wrist and
clip the other end of the strap to the metal frame of the
system unit.
Unpack the removable media drive that you are installing.
Figure D-5, on page D-6, shows an RX23 disk drive and

Choose a SCSI ID number for the drive. Follow these
steps:
Read the device codes that you wrote down in step 4.
In the example, we wrote rz2 and tz1.
Choose any number from 0 to 6 that is not already used
in the device codes displayed on the screen in the DEV
column. In this example, we can choose 0, 3, 4, 5, or 6
because the numbers in the device codes are 1 and 2.
In this example, assume that we chose 4.

Internal Hardware Options 5–43

Write down the new number on the same paper where
you wrote the device codes.
Use a pair of needle-nose pliers to set the SCSI ID number
on the drive that you are installing. Set the new SCSI ID
number that you chose by arranging the SCSI switches or
jumpers to that number, as illustrated in Appendix D of
this guide.
If your drive uses jumpers, the jumpers are already on the
pins, and you have to arrange them appropriately. Each
removable media drive must have its own unique SCSI ID
number to function properly.
Caution: Some drives have extra switches and pins. The drives
use them for other settings, and you should not change them. For
example, on the RRD42 optical compact disc drive, the pin on
the left adjusts the drive for your worksystem operating system.
The drive is shipped to you with a jumper on the pin, and you
should leave the jumper there. Figure D-6, on page D-6, shows
the RRD42 drive.

internal, hard disk drives, carefully press the cables around
the drives.
Lower the end of the drive bracket all the way onto the two
posts that support it.
If you cannot seat the end of the bracket on the posts, you
probably didn’t press the power supply and SCSI cables all
the way down into the system unit. Raise the end of the
bracket and arrange the cables again.
Tighten the two captive screws on the end of the drive
bracket until they are at least finger tight.
Tighten the two captive screws that hold the front drive

Installing and Removing External Storage Devices
To Install External Storage Devices
Connect external storage devices to form a chain, including as
many as seven devices in each chain. Each device must have a
separate SCSI ID number so the workstation can identify the
device.
If your workstation has more than one SCSI connector,
distribute the devices among all the SCSI connectors on the
system unit. For example, if you have seven devices, one base
system SCSI controller, and one TURBOchannel SCSI controller
option module, install three drives on one SCSI connector and
four drives on the other.

Troubleshooting 10–13

Is It Working?
Self-tests are programs that check your workstation hardware
to be sure that it is functioning properly.
Self-tests have numerous subtests that examine specific
workstation components. When a subtest discovers a problem,
it displays a coded message, called an error message, on the
screen. When all the tests are done, the workstation displays
the console prompt (>>).
How to Run a Self-Test
The workstation runs a small set of power-up self-tests
automatically when you turn on the power. It can run
two versions of the set, depending on the setting of the
testaction environment variable. Chapter 11, ‘‘Environment
Variables’’, on page 11-22, explains how to set environment
variables.
You can run the full set of self-tests, collectively called
the system self-test, at any time. However, you must shut
down your ULTRIX worksystem software first. To do so,
type shutdown -h now at the ULTRIX prompt and press
Return. Then, at the console prompt (>>), type test and
press Return.

10–14 Troubleshooting

How to Interpret Self-Test Messages
Self-tests display error messages when they discover problems
in the hardware.
If the slot number is 0, 1, or 2, the problem is in the
TURBOchannel option slot that has the same number.
If the slot number is 3, the problem is in the base system
hardware. Copy the messages and then look for them in
Table 10-3, on page 10-16. This table explains how you
can probably fix the problem. If you cannot fix it, call your
system manager or Customer Support Center.
Here is a sample error message, with an explanation of every
part:

The RAM cache in the CPU module is faulty. Copy the entire message
and call your system manager or Customer Support Center.

The math coprocessor in the CPU module is faulty. Copy the entire
message and call your system manager or Customer Support Center.
RAM is faulty. Make sure that all memory modules are firmly seated
in their connectors in the system unit. Then run the memory test.
Type t 3/mem * and press Return. The memory test checks every
memory module, taking several minutes for each one. If it finds a
problem, it displays one of two types of message. The first type of
message has this format:

?TFL: 3/mem (PER, cause=0000001C, DBE = 004000c,
Bank 1, D16-31, d23-d16)
The message identifies the faulty memory modules. The bank number
is the number of the memory slot. Bank 1 is the bank number in
the example. Bank numbers can be 0 to 7. Bank 0 is the memory slot
nearest the back of the system unit; bank 7 is the slot nearest the
front. The SIMM number is the memory module in the slot. D16-31
is the SIMM number in the example. SIMM numbers can be D0-15
or D16-31. D0-15 is the memory module next to the power supply;
D16-31 is the memory module away furthest the power supply.
You should replace every memory module for which an error message
appears. Chapter 4 explains how to replace memory modules.
If the messages show that all memory modules are faulty, remove
all of them. Then install at least 8 megabytes of memory with new
memory modules and run the system memory test again. If the test
still reports a problem, copy the entire message and call your system
manager or Customer Support Center.
The second type of message that the memory test displays has this
format:

?TFL: 3/mem (@ A04000000=55550055, sb 55555555)

Using the Console Commands
This chapter tells you how to
Select console and operating modes
Use the console commands
Set environment variables

Using the Console Commands 11–1

Console and Operating Modes
Your workstation functions in two modes: console mode and
operating mode. Console mode lets you use the setup and
testing software that is built into the workstation. Operating
mode lets you use your worksystem software.
This manual explains how to use the workstation in console
mode. Your worksystem software manuals explain how to use
the workstation in operating mode.
Using Console Mode
The workstation starts in console mode and stays in that mode
until you start your worksystem software. While you are in
console mode, you can use the console commands, which are the
commands of the built-in setup and testing software.
You enter console commands at the system console. If you
connected only one monitor to your workstation, that monitor
is your system console. If you connected multiple monitors,
the monitor in the TURBOchannel option slot with the lowest
number is the system console. If you connected a separate
system console, such as a VT320, and you have typed setenv
console s, that console is your system console.
You use console mode and console commands for such tasks as
Running workstation self-tests
Displaying workstation hardware configurations
Setting workstation environment variables
Booting (starting) the operating system
To choose console mode, take one of the following actions:
If you are using ULTRIX worksystem software, type
shutdown -h now at the ULTRIX prompt and press
Return, or
Caution: If you do not shut down ULTRIX, you may lose the

work that you were doing.

Press the halt button on the back of the system unit, or

11–2 Using the Console Commands

Turn off the power to the system unit and turn it back on
again.
Caution: Turning off the power or pressing the halt button with

your workstation and any worksystem software running may
result in the loss or corruption of data.
Console prompts

When you use console mode, the workstation displays one of
these two prompts on the system console screen: >> or R>.
The >> prompt means that the workstation is in privileged
mode. Anyone can use all the console commands.
The R> prompt means that the workstation is in restricted
mode. Users who don’t know the password can use only the
boot and password console commands.
Using Operating Mode
You use the workstation in operating mode most of the time,
because that is the mode for using your worksystem software.
This software consists of an operating system and applications.
You use it for such activities as
Running applications in DECwindows
Backing up files
Sending and receiving electronic mail

Using the Console Commands 11–3

To choose operating mode, boot (start) the operating system in
either of these ways:
Type boot at the console prompt and press Return, or
Set the worksystem software to boot the operating system
automatically.
For either of these procedures to work, you must set the
boot environment variable for your workstation and set the
haltaction environment variable to b. Until you set these
variables, you must use the boot command. This chapter
explains how to use the boot command and how to set the
environment variables.
When you start in operating mode, you must supply your
worksystem software user name and password.
Your worksystem software manuals explain how to use
operating mode.

11–4 Using the Console Commands

Typing Console Commands
You can use the console commands when the system monitor
displays the prompt >> or R>. Follow these rules:
Type uppercase and lowercase letters exactly as they
appear in this manual. The system recognizes uppercase
and lowercase letters as different input.
Press Return after typing a command.
Use these key combinations:
Ctrl-s freezes the screen display.
Ctrl-q releases a frozen screen display.
Ctrl-c aborts a command.
Ctrl-u erases a partially typed command line.
DEL erases the last character typed.
To type a hexadecimal number, precede the number with
0x (zero x). To type an octal number, precede the number
with 0 (zero). To type a decimal number, do not precede the
number with any leading 0’s (zeroes).
To use the Ctrl commands, hold down the Ctrl key while
you type the letter of the command. For example, to use
Ctrl-s, hold down Ctrl while you type s.

Using the Console Commands 11–5

Conventions Used in This Chapter
Letters in boldface type like this should be typed
exactly as they appear.
Words in italic type like this OR LIKE THIS are options
and arguments for the commands. You have to replace
them with the appropriate information. For example, the
script command has a scriptname argument. When you
type the command, you replace scriptname with the name
of the script that you are typing.
Options are read by the console programs, whereas
arguments are read by the worksystem software.
When options and arguments are shown in brackets, you
should use them only if they are appropriate. When they
are not in brackets, you must use them all the time. For
example, the printenv command is shown like this:
printenv [env]

Because [env] is enclosed in brackets, you should use it only
when it is appropriate, which in this case is when you want
to display the setting of one environment variable.
The script command is shown like this:
script scriptname

Because scriptname is not shown in brackets, you must
include it in every script command.
Do not enclose options and arguments in brackets when
you type them. The brackets are just this manual’s way of
showing you when to use options and arguments.
When an argument is followed by an ellipsis (...), you can
use more than one argument with the command.

11–8 Using the Console Commands

Description of the Console Commands
To use a console command, type the command as shown, add
appropriate options and arguments, and press Return.
For clarity, the console prompt (>>) precedes the format
descriptions.
?
>>? [command]

The ?, or help, command displays the list of console commands,
as shown on page 11-8. If you name a specific command, the
screen displays the help message for that command only.
boot
>>boot [OPTIONS]

[#/path] [argument...]

Options can be
-a
-n
-z number

Use a multiuser bootstrap.
Load, but do not execute, path program.
Wait for number seconds; then boot.

The boot command loads and executes the program specified by
#/path, where # is the slot number of the device that you are
booting from, and path is the file specification of the program.
The -a argument boots for a multiuser environment; to perform
a single user boot, enter the boot command without the -a
argument. The -n option suppresses execution of the program
after it is loaded. The -z option causes the system to wait before
booting. When you enter the command with no options, path,
or argument, it uses the options, path, and argument in the
boot environment variable (see ‘‘Environment Variables’’ on
page 11-22).

Using the Console Commands 11–9

The following example of the boot command uses the options
and arguments set in the boot environment variable:
boot

The following command boots from a tape drive (tz5) in base
slot 3; tz5 is the SCSI code of the drive:
boot 3/tz5

The following command boots from the network that is
connected to your workstation at option slot 2:
boot 2/mop

The following example shows a multiuser boot (-a) using the
vmunix file on an internal drive (rz1) in base slot 3; rz1 is the
SCSI code of the drive:
boot 3/rz1/vmunix -a

cat
>>cat #/scriptname

The cat command displays the contents of the script specified
by scriptname. The # argument indicates the number of the
slot where the script is stored.

11–10 Using the Console Commands

cnfg

choose. If you do not indicate a format, the system displays the
data in hexidecimal format.
The -S option fetches the contents of each address in the
address range count times. The screen displays only the final
value in each range.
erl
>>erl [-c]

The erl command displays the log of error messages. The
system records error messages in a special error log buffer, and
the erl command displays the contents of this buffer. If you
specify -c, the buffer is cleared. The system stops recording
error messages when the buffer is full and resumes when the
buffer is cleared.
go
>>go [address]

The go command transfers control of the workstation to the
specified address. If you do not specify an address, go uses the
execution address returned by the last boot -n command. If
the boot -n command has not been executed and no address is
specified, the system ignores the go command.
init
>>init [#] [argument...]

The init command initializes module hardware. If you specify
a slot number (#), the command initializes the modules in that
slot only.
Arguments are specific to each module.

Using the Console Commands 11–17

ls
>>ls [#]

The ls command displays a list of the files in a module ROM. If
you do not specify a slot number (#), the command lists the files
for all modules.
passwd
>>passwd [OPTIONS]

Options can be
-s
-c

Set a new console password.
Clear the console password.

Use the passwd command to enter, set, or clear your console
password.
The console password keeps unauthorized people from using
the console commands on your workstation. You do not need to
use the password if security is not an issue in your workplace.
When you first set up your workstation, you do not need a
console password. The only way that a console password can be
required is if you choose to start using one.1
To start using a console password, type passwd -s and press
Return. The system displays a prompt (pwd:) asking you to
type the password that you want to use. Type a word with
at least six characters. You can use letters and numbers;
the system recognizes the difference between uppercase and
lowercase letters.
The system displays the pwd: prompt twice. Type the same
password each time. For the sake of security, the screen does
not display what you type, so type something that is easy to
remember.
Once you choose a password, the system displays the restricted
console prompt R> when you first start up your workstation.
1

The console password is not the same as the passwords required by your worksystem software
or networks. The console password protects your workstation hardware by controlling access
to the console commands.

11–18 Using the Console Commands

At this prompt, you can only boot your worksystem software or
enter your console password.
Boot your worksystem software. Type boot and press
Return. This is the only boot command that you can use.
It has no options or arguments. It uses the values that you
set in the boot environment variable (see ‘‘Environment
Variables’’, on page 11-22). If you have not set the boot
variable, the command does not work.
Enter your console password. Type passwd and press
Return. Then type your console password at the pwd:
prompt. For the sake of security, the screen does not
display what you type.
After you enter your console password, the prompt changes
to the standard console prompt (>>), and you can use all the
console commands that are described in this chapter.
To stop using your console password, type passwd -c at the
standard console prompt and press Return. You will then have
unrestricted access to the console commands.
printenv
>>printenv [env]

The printenv command displays the values of environment
variables. If you specify the name of an environment variable,
the command displays the value of only that variable. See
‘‘Environment Variables’’, on page 11-22 for more information.
restart
>>restart

The restart command attempts to restart the worksystem
software. This command relies on a restart facility in the
worksystem software that you have to enable.

Using the Console Commands 11–19

script
>>script scriptname

The script command allows you to write a short, temporary
script, or small program, at the system console. After you write
the script, you can run it with the sh command, or you can type
the name scriptname of the script alone.
To write a script, type script and a name for the script. Then
press Return. Then write the script line by line. When you are
done, go to a new line and press Return.
setenv
>>setenv env value

The setenv command sets the value of an environment variable.
Note that you must enclose the command in double quotation
marks if value contains blank spaces. See ‘‘Environment
Variables’’ on page 11-22 for more information.
sh
>>sh [OPTIONS] [#/scriptname] [argument...]

Options can be
-e
-b
-v
-S
-l

Exit on error.
Branch to script.
Verbose; echo to console.
Suppress script-not-found errors.
Execute in a loop. (Note that this option is the letter ‘‘l,’’
not the number 1.)

The sh, or shell, command activates, or runs, a script. Replace
# with the slot number of the module that contains the script.
If you specify a script name for scriptname, the script is used
as the input. Otherwise, what you type at the console is the
input, and a subshell is created. When you run a shell script,
environment variable 0 is set to the script name, 1 is set to the
first argument in the script, 2 is set to the second argument,
and so on.

11–20 Using the Console Commands

The -e option directs the shell to exit when an error occurs.
Normally, the shell ignores errors. The -b option executes the
script specified by scriptname instead of creating a subshell.
The -v option causes the script to be echoed to the console
when it is executed. The default option is no echo. The
-S option suppresses any error message if the script is not
found and causes the sh command to return a status that
indicates success. The -l option causes a script to be executed
continuously until a system reset occurs or you press Ctrl-c.
t
>>t [OPTIONS]

#/testname [argument...]

Options can be
-l

Execute in a loop. (Note that this option is the letter ‘‘l’’
and not the number 1.)

The t, or test, command runs module tests. Specify a test with
#/testname, where # is the slot number and testname is a
module-specific test.
The -l option makes the test run continuously until a system
reset occurs or you press Ctrl-c.
If the t command is part of a script, the system console displays
#/testname as each test is run.
To display the tests and test formats for a specific module, type
t #/?, where # is the slot number of the module.
Type test to run the script that performs a thorough test of
the entire system. Typing test is a shorthand way of typing sh
3/test. If you type sh -l 3/test, the test runs continuously.
unsetenv
>>unsetenv env

The unsetenv command deletes the value of an environment
variable. See ‘‘Environment Variables’’ on page 11-22 for more
information.

Using the Console Commands 11–21

Environment Variables
Environment variables store system parameters and scripts and
pass information to the operating system. Some environment
variables stay in memory, but others are lost when you turn off
the power.
Table 11-4 summarizes the console commands for setting
environment variables. Table 11-5 lists the standard
environment variables that you can set.
Table 11-4. Console Commands for Environment Variables
Command

Description

printenv
setenv
unsetenv

Displays the value of environment variables
Sets the value of an environment variable
Deletes the value of an environment variable

Table 11-5. Environment Variables Set by the User
boot1
console1

Specifies arguments for the boot command (see page 11-9).
Chooses the system console. You normally do not set this
variable, instead leaving your monitor and keyboard set as
the system console. This ‘‘blank’’ setting and any setting
other than s also select autoconfiguration, which causes
the system module to scan the rest of the hardware on
the workstation so that the module can use the hardware
correctly. Autoconfiguration makes the monitor in the lowestnumbered option slot the system console. If the option slots do
not contain any graphics modules, communications connector
3 is the system console slot.
To display the language menu on the system console, set
console to zero.
If more than one monitor is connected to the system unit, the
monitor in the lowest-numbered slot is the system console.

1 These environment variables stay in memory until you delete them.

(continued on next page)

11–22 Using the Console Commands

Table 11-5 (Cont.). Environment Variables Set by the User
haltaction1

testaction1

Specifies what happens when you press the halt button or
turn on the power:
b
Boots the worksystem software, as specified by the
boot environment variable.
h
Halts the worksystem software and displays the
console prompt.
r
Restarts the worksystem software. If the restart fails,
boots the software.
Specifies the greatest number of lines of text that can fit on
the screen at one time. When text scrolls on the screen, the
system stops the scrolling at the number of lines that you set.
If you set the number to zero, the text scrolls continuously.
Controls the power-up self-test:
t
Specifies a thorough (but slow) testing of the system.
q
Specifies a quicker but less thorough test.
m
Specifies manufacturing tests. You should not use this
setting.
The number of the module that contains the current script. If
no script is active, the system module is assumed.

1 These environment variables stay in memory until you delete them.

There are other environmental variables. Some, like oconsole,
should not be changed. Others can be set as implementationspecific side effects of various bootstrap and test procedures.

Setting SCSI ID Switches
If two or more drives have been given the same SCSI ID
numbers, you must reset the SCSI ID numbers on these drives,
so that each drive will have its own unique SCSI ID number.
Depending on the type of drive you are installing, different
methods may be required to set the SCSI ID switches that set
the SCSI ID numbers. Some drives use toggle switches to set
the SCSI ID numbers, and other drives use a system of pins
and jumpers, as shown in Figures D-1 through D-7.
To set the SCSI ID numbers on your drives, you may need
medium flat-blade and Phillips screwdrivers and small needlenose pliers.

The RZ25 has front and side jumpers. Pin 4 on the front
jumpers must always be in place. When the side jumpers are
used, all pins except pin 4 must be removed from the front
jumpers.
