Preface
The hardware for the MicroVAX 3500 and VAXserver 3500 systems is the

same.

The software differs because the systems serve different functions.

The MicroVAX 3500 is a timesharing system that uses the VMS, ULTRIX, or
VAXELN operating systems, and functions as an end-node on an Ethernet

network. The VAXserver 3500 is a full-function network node that uses the
VMS operating system and LAVc (Local Area VAXcluster) software.
This manual describes how to use the MicroVAX 3500 and VAXserver 3500

systems. The manual is structured as follows:

Chapter 1 provides an overview of the systems.

Chapter 2 describes how to use each system.

Chapter 3 describes how to use options installed in the systems.

The appendix lists related documentation.

A glossary explains key terms.

NOTE: VAXserver 3500 systems are designed to offer maximum performance
for applications that do not require timesharing.

Some of the devices referred

to in this manual are designed for multiuser systems and may not be suitable

for a VAXserver system.

Contact your DIGITAL representative if you have any

questions about whether use of a specific device is appropriate for your VAXserver
system.

System Overview
This introductory section describes the MicroVAX 3500 and VAXserver 3500
systems.

MicroVAX 3500 and VAXserver 3500 systems contain all system components

in a pedestal-mounted BA213 enclosure.

The BA213 enclosure houses the

following;:

(entral processing unit (CPU)

Memory modules

Communications controllers

Mass storage controllers

RA70 disk drive (optional)

RDb54 disk drive (optional)

TK70 tape drive

Power supplies

Depending on the configuration you ordered, your system contains an RA70
disk drive(s) or an RD54 disk drive(s).

RAZ70-based systems contain one or two RA70 disk drives.

RDb54-based systems contain one to three RD54 disk drives.

The illustrations in this manual show RA70-based systems.

This chapter describes the MicroVAX 3500 and VAXserver 3500 system

components and their functions. The front of the system has a removable front
panel that restricts access to some of the system controls. The front panel,
the enclosure behind the panel, and the function of the system components
are described in turn.

Chapters 2 and 3 describe how to use the system and options.

The front panel has a sliding window controlled by a 3-position rotary
lock.
You can lock the window in one of three positions: closed, partially
open,
and fully open. Each position limits access to certain system controls. When
the window is locked in any of its three positions, you can still raise it
to a
higher position. However, you cannot lower it beyond the locked position

without using the key.

To open the window, turn the key to position 2 or 3, then slide the window
down. To close the window, slide the window up, then turn the key to
lock

the window in position.

Mass Storage Shelf

The mass storage shelf extends across the top of the
enclosure.

The shelf

contains a TK70 tape drive and a fixed-disk drive(s)
(either RA70 or RD54).

The fixed-disk drives are behind the control panel.
Figure 1-8 shows the
control panel of an RA70-based system. Figure 1-9
shows the control panel

of an RD54-based system.

The fixed-disk drive control panel has several buttons
and indicators for each
drive which light when the system is turned on. Chapter

If the DC OK light is not lit, contact your DIGITAL service

representative.

RA70-based systems have a halt button to the left of the DC OK light.
The Halt button is a two-position button. When you press in the button,
the system halts and the console mode prompt >>> appears on the console
terminal screen. Before you can enter console commands, press the Halt
button again to return it to the out position. Now you can enter console

commands. If you inadvertently press the Halt button, type “c [Retun]” to
continue.

CAUTION: Pressing in the Halt button halts the system regardless of the setting
of the Break Enable /Disable switch on the CPU cover panel.
Some early models of RA70-based MicroVAX 3500 and VAXserver 3500
systems do not have a Halt button. You halt these systems by pressing the
key, after setting the Break Enable/Disable switch on the CPU cover
panel to enable. Chapter 2 describes halting the system in more detail.

Operating the system without the module cover panels has the following
consequences:

The system may overheat due to improper air circulation.

The system will not comply with FCC and VDE requirements for shielding
and may produce electrical interference that affects other equipment.
The system is susceptible to electrical interference or damage from external
sources.

as communications controllers (excluding Ethernet cable connections),
have

recessed cover panels that are riveted directly to the module.

The recessed
panels allow space for connecting cables.
Modules requiring no external
cable connections, such as mass storage controllers, are covered by flush

cover panels. Empty slots are also covered by flush cover panels which
may

- be single or double width.

All cover panels, except those covering empty
slots, have a label identifying the module installed in the slot.

Cables connecting your system to peripheral devices (such as terminals,
modems, and printers) are attached to communications controllers.
Each
cable can contain multiple lines. The cables run under the BA213 enclosure

and out the back of the enclosure, where the cables are split into individual
lines. Chapter 3 describes these connections in more detail.

The central processing unit (CPU) module is installed in slot 1

associated memory module in slot 2.

with its

Additional memory modules may be

installed in slots 3 through 5. The CPU and the first memory module
are
behind a double-width cover panel that has internal cable connections to
the
CPU module. Figure 1-11 shows the CPU cover panel.

CPU Cover Panel Components
The CPU cover panel has the following components:
*

Break Enable/Disable switch—When the switch is down (dot outside

the

circle), breaks are disabled. When the switch is up (dot inside the circle),
breaks are enabled. When breaks are enabled, pressing
on the
console terminal halts the processor and transfers control to the console

program. When you change the switch from one setting to the other,
you must activate the new setting by resetting the system. To reset
the
system, press the Reset button on either power supply. All processes
will

be interrupted.
*

Power-Up Mode switch—This 3-position rotary switch determines how

the system responds at power-up:

Language Inquiry Mode (in the top position, indicated by a human
profile) causes the system to display a language selection menu at

power-up if your console terminal supports multiple languages.

Run Mode (in the middle position, indicated by an arrow) is the

normal operating setting.

Loop Back Test Mode (in the bottom position, indicated by a T in a
circle) causes the system to run loopback tests on the console serial

line at power-up.

This setting requires special loopback connectors

and is for DIGITAL field service use only.

The light-emitting diode (LED) display shows the testing sequence during
power-up.

(Console terminal connector—This modified modular jack (MM]), labeled
A-1, provides the connection for the console terminal.

1.1.1.3 Power Supplies
Your system has two power supplies.

The one on the right is the primary

power supply; the one on the left is the secondary power supply. Figure 1-12

functions used by the system.

1.2.1.2 Console Serial Line Unit (SLU)
Each system has a serial line unit (a line on which each bit of informatio
n
is sent sequentially on a single channel) connecting the console terminal
to

the CPU module. The SLU connector (an MM]) is located on the CPU cover

panel.

CPU.

The console serial line provides a means of communicating with the

1.2.1.3 Main Memory
Main memory provides the physical storage area for data and instruction
s
used by the CPU. When you start your system, the operating system is
loaded
into main memory. Application programs must also be loaded into memory.

When the system cannot load everything into memory at once,
it reads in
units of data called pages (512 bytes of data) from disk. Having a large
main

memory increases the efficiency of processing, since fewer pages
must be

1-16

MicroVAX 3500 VAXserver 3500 Operation

copied to and from disk. Each configuration comes with a standard memory
option that you can upgrade to increase efficiency.
The contents of memory are volatile.

This means they are lost when you
turn off power to the system. Use mass storage devices, such as fixed disks
and tape cartridges, to store software and data permanently.

1.2.1.4 Mass Storage Devices and Controllers
Mass storage devices record data on magnetic media.

The data recorded is

not lost when you turn off the system, but can be altered or erased if you
record over the data.

Use mass storage devices to store data and software
permanently. When the data or software is needed, the CPU copies it from
the mass storage device into main memory. The two primary types of mass
storage devices are fixed disks and devices with removable media, such as
tape cartridges.

Fixed-Disk Drives

Fixed-disk drives are installed in your system.

They provide large-capacity

storage for software and data files, as well as rapid access to the data by the
CPU. Your system may have multiple fixed-disk drives.
Devices with Removable Media
Devices with removable media, such as disk packs, tape cartridges, and tapes,

are used as both input and output devices. You use them as input devices
when you install software or copy data to your system. Tape cartridges are
the primary media for loading software.

You use these devices as output

devices when you copy software or data from your system.

You can copy
individual files or programs, or you can copy (back up) the contents of an
entire fixed disk. Tapes and disk packs are commonly used to archive data
from systems.

Mass Storage Controllers

All mass storage devices require a controller, a separate module that controls
activity between the CPU and the mass storage devices. The controller for
the TK70 tape drive (the TQK70) and the controller
for the fixed-disk drives

are installed to the left of other modules in the card cage. (RA70 fixed-disk
drives require a KDA50 controller; RD54 fixed-disk drives require an RQDX3
controller.)

System Overview

1-17

1.2.1.5 Power Supplies
The system has two power supplies.

The primary power supply provides

power to modules installed in slots 1-6, one or two mass storage devices (the

TK70 tape drive and fixed disk 1, if present), and the two fans. The second

power supply provides power for modules in slots 7-12 and fixed disk 0.

1.2.1.6 Fans
Two fans located near the bottom of the system draw in air from the top of
the system and pull it down through the modules and out the bottom. The
speed of the fans varies, depending on the surrounding room temperature.
To reduce the load on the fans, keep the system away from heat sources.

1.2.2 Optional Components
System options can include multiples of components that are part of the base
system (for example, additional memory modules or disk drives) and the
following kinds of options:
¢

Communications controllers

Real-time controllers

Printer interfaces

1.2.2.1

Communications Controllers

Besides the console serial line, most systems have additional communications
controllers for connecting additional terminals, and for communicating with
other systems over telephone or network lines. Communications controllers

provide standard interfaces between peripheral devices and the system. Many
communications controllers provide support for multiple data lines.

The following types of communications controllers are available:
®*

Asynchronous serial controllers

Synchronous serial controllers

DECservers

Network controllers

Serial controllers transmit data one character at a time.

A device at the

transmitting end breaks bytes of data into bits. A device at the receiving end

assembles incoming bits into bytes of data.

1-18

MicraVAX 3500 VAXserver 3500 Operation

Asynchronous Serial Controllers
Asynchronous serial controllers provide low-speed connections between
peripheral devices and the system. Asynchronous communication between

the system and the peripheral depends on recognition of a pattern of start
and stop bits, not on a time interval.
Asynchronous serial controllers may be divided into those without modem
support and those with modem support.

You use serial controllers without modem support to connect additional
terminals and printers to your system. For example, the CXA16 module
provides connections for up to 16 serial lines with no modem support.
NOTE: Printers equipped with a microprocessor (intelligent printers) may require
Do not attach a printer requiring
modem control signals to a controller with no modem support. Check your printer
documentation to determine the proper communications interface for your printer.
modem control signals to function correctly.

Communications controllers with modem support allow you to communicate
over telephone lines.

With a modem connected to your system, you can

access other computers and you can dial into your system from a remote
terminal or computer.

Computers transmit digital signals, while telephone lines (with the exception
of digital leased lines) transmit analog signals. @~ When two computers
communicate over telephone lines, a modem is required at both the
transmitting and receiving end of the line. At the transmitting end, the
modem converts digital signals from the computer (or terminal) to analog
signals prior to transmission over telephone lines.

At the receiving end,
another modem converts the analog signals from the telephone line back into
digital signals the computer can understand.

The degree of modem support depends on the number of modem control
signals recognized by the device. Full modem support (according to DIGITAL
standards) requires recognition of eleven signals. The CXY08 module supports
up to eight serial lines with full modem support.

Synchronous Serial Controllers
Synchronous serial controllers provide high-speed connections between
systems.
Communication between synchronous devices depends on

time intervals that are synchronized before transmission of data begins.
Synchronous devices can also have modem support.

System Overview

1-19

DECservers
DECservers are terminal servers (a combination of hardware and software)
that allow you to connect multiple terminals or printers to hosts in an Ethernet

Loca Area Network (LAN).

Terminal servers perform the functions of traditional data terminal switches
but multiplex the lines over the Ethernet.
Using a DECserver offloads
communications processing from the host system.

Network Controllers
Network communications controllers allow you to connect to an Ethernet

local area network or other network types.

With a network connection and

appropriate DECnet software, you can use network services, such as
mail;

access data stored on other systems; perform operations, such as editing and
printing on remote systems; and share resources, such as laser printers.

1.2.2.2 Real-Time Controllers
Real-time controllers interface devices that monitor processes, for example,
laboratory equipment or manufacturing equipment connected to the system.

Typically, real-time controllers are parallel devices, not serial devices. Parallel
devices transmit more than one bit of information simultaneously.

1.2.2.3 Printer Interfaces
Some printers require specific interfaces to communicate with the system. For
example, the LG01 and LGO02 require the LPV11-SA interface.

1.2.2.4 Other Available Options
Your system arrives configured with the options you ordered. As your needs
change, you can add more options. Your DIGITAL sales representative can

advise you on available options. MicroVAX 3500 VAXserver 3500 Technical
Information describes the options currently available for MicroVAX 3500 and
VAXserver 3500 systems. DIGITAL provides installation for additional options

that you order.

Chapter 2

Using the System
This chapter describes how to use your system once the system software has
been installed.

2.1

Before You Use a New System

This chapter assumes that your system has been properly installed by a
DIGITAL service representative. Installation includes running the diagnostic
software shipped with your system. To install operating system options or

layered products, see the instructions in your system software installation
manual or layered product installation manual. Some of the instructions may
require you to remove the front panel of the system to change switch settings.
The remainder of this chapter assumes that system software has been installed.

2.2 Switch Settings
Switch settings vary, depending on the operation being performed. The next
two sections describe switch settings for normal and for special operations.
Set the switches according to your needs.

2.2.1

Normal Operation

Switch settings for normal operation are the following;:
e

RA70-based systems: The Halt button on the mass storage control panel
1s set to out.

The Break Enable/Disable switch on the CPU cover panel is set to
disable (down position). With break disabled, your system automatically
boots system software when powered up.
Once system software is
installed, DIGITAL recommends you run your system with break disabled
to prevent the user of the console terminal from inadvertently halting

the system by pressing

on the console terminal. Halting the system

causes all activity to stop.

Using the System

2-—1

CAUTION: Pressing in the Halt button on RA70-based systems halts the
system regardless of the setting of the Break Enable/Disable switch on the
CPU cover panel.
The Power-Up Mode switch on the CPU cover panel is set to Run
(indicated by an arrow).

The baud rate switch, located on the inside of the CPU cover panel,
is set to 9600.

If you need to change the baud rate, for example, to

use a non-DIGITAL terminal, you must remove the CPU cover panel.

Instructions on changing the baud rate are in MicroVAX 3500 VAXserver

3500 Technical Information.
RA70-based systems: The Write-Protect button for each RA70 fixed-disk
drive is set to out (not lit).
RA70 drive is in.

Either the A or B button (or both) for each

This setting puts the drive on-line.

The difference
between A and B is the port used for communications between the drive

and the controller.

RD54-based systems: The write-protect switch for each RD54 fixed-disk
drive is in the write-enabled (up) position.

2.2.2 Special Operation
Certain operations require that you change some of the normal operating
settings.

If you need the ability to halt the system from the console terminal,
for example, when installing system software or performing certain types

of backup, you can set the Break Enable/Disable switch to enable (up
position).

This allows you to halt the system by pressing

on the

console terminal.

NOTE: When you change the Break Enable /Disable switch from one setting
to the other, you must activate the new setting by resetting the system. To
reset the system, press the Reset button on either power supply. All processes
will be interrupted.
RA70-based systems:

If you have an RA70-based system, it is not
necessary to change the setting of the Break Enable/Disable switch. Halt

the system by pressing the Halt button to the left of the DC OK light.

If your system has been powered off for more than seven days, the
battery unit that saves the system clock and the language selection may
be depleted.

Each time you power up the MicroVAX/VAXserver 3500
system, the CPU determines whether or not the battery power is sufficient.

2—2

MicroVAX 3500 VAXserver 3500 Operation

If the battery power is depleted, the Language Selection Menu appears,

The console terminal first displays a line of information identifying the CPU,
the version of the microcode, and the version of VMB—the primary bootstrap
program.

In the sample screen shown in Figure 2-2, the CPU is identified

as a KA650-A, the version of the microcode is V04, and the version of VMB

is 0117. These version numbers may differ from those on your system. The
console terminal then displays a countdown as the system tests itself. When
the self-tests are successful, the system either autoboots system software or
goes into console mode, as described in Section 2.4.1 and Section 2.4.2.

2.4 Booting the System
The system boots in one of two ways.

You can manually boot the system

from console mode, or you can configure the system to autoboot on power-up.
The setting of the Break Enable/Disable switch determines how the system

boots.

2.4.1

Autobooting the System

When the Break Enable/Disable switch is set to disable, the down position
(the normal operating setting), the system runs self-tests.

On completion of

the self-tests, the system attempts to load system software from each bootable
device in the order shown in Table 2-2.
When the system is ready to load system software, the message “Loading
system software” displays on the screen.

The system begins testing devices

when the number “2” appears on the screen. As the system attempts to boot

from each device, the device name displays on the console terminal.
When the system begins booting from a device, the countdown continues

from 1 to 0, as shown in Figure 2-3.

3.1.1

Fixed-Disk Drives

Fixed-disk drives provide high-volume mass storage for the MicroVAX 3500

or VAXserver 3500 system.

If your system contains RA70 disk drives, you may have one or two
fixed-disk drive(s) located within the BA213 enclosure.

If your system contains RD54 disk drives, you may have up to three
fixed-disk drives(s) located within the BA213 enclosure.

When your system has multiple disks, we recommend that you separate them
according to function.

For example, if your system has two disks, you may

want to use them as follows:

Disk 0 contains the operating system and applications installed on the
system.

Disk 1 contains work areas for each user with an account on the system.

If your system has three disks, you may want to use them as follows:
*

Disk 0 contains the operating system and applications installed on the
system.

Disk 1 contains a database or files accessible to all users, subject to the
normal file protection explained in your software manuals.

Disk 2 contains work areas for each user with an account on the system.

Refer to your system software manual for a description of procedures required
to name and access multiple disks.

The storage capacities and other specifications of each fixed-disk drive are
listed in MicroVAX 3500 VAXserver 3500 Technical Information.
For more information about the fixed-disk drive(s) in your system, refer to
the section on that particular drive. If your system contains RA70 fixed-disk
drives, refer to Section 3.1.1.1.
If your system contains RD54 fixed-disk

drives, refer to Section 3.1.1.2.

If you want to write-protect a disk containing sensitive data that you do not
want changed or accidentally erased, set the Write-Protect button to in (lit).
3.1.1.2 RD54 Fixed-Disk Drives

Your system may have one to three RD54 drives located behind the panel
to the left of the tape drive. Each drive has a green activity light and
write-protect switch, as shown in Figure 3-2.

The activity lights operate only when a disk is installed. For example, if your
system has one fixed-disk (fixed disk 0), only the right-most light is active.
The other two lights remain unlit.

The activity lights glow steadily for a few seconds when you turn on the
system. They blink rapidly during read/write activity to the disks.
Above the activity light for each fixed disk is a write-protect switch. The
switches are recessed to prevent accidental changing of the switch position.
Use a pen tip or other small tool to change the switch setting.
When the switch is in the up position, the disk is write-enabled. The system
can read and write to the disk. Your system disk and disks containing work
areas for users should be write-enabled, the normal operating setting for most
disks.

When the switch is in the down position, the disk is write-protected. The
system can read data from the disk but cannot write data to it. You may
want to write-protect a disk containing sensitive data that you do not want

changed or accidentally erased.

MicraVAX 3500 VAXserver 3500 Operation

You can use a COMPACTape Il or COMPACTape cartridge as an input device
to load software or data into your system. The TK70 drive can read data
on both types of cartridges, written by either a TK70 drive or a TK50 drive.
(The TK50 drive records data in a format different from that of the TK70.)
You should use a COMPACTape II as an output device to make copies or
backups of software or data. The TK70 drive cannot write to a COMPACTape
Il or COMPACTape that has been written by a TK50 tape drive.
TK70 Tape Drive Controls

The tape drive has two primary controls: the cartridge insert/release handle
(subsequently referred to as “the handle”) and the Unload button. You use
the handle to insert or remove cartridges and lock them into position. Pull
the handle open to insert or remove a tape cartridge. Push the handle closed
to lock a tape cartfidge into position and load the tape.

You use the Unload button to rewind and unload the tape. Unloading and
rewinding can also be controlled by software. Refer to your system software
manuals for appropriate commands.

The drive also has three indicator lights that let you know the status of the
drive.

Orange light (Write-Protected): A steady orange light indicates that the
cartridge is write-protected.

Yellow light (Tape in Use): A steady yellow light indicates that the tape

Green light (Operate Handle): A steady green light indicates that you
can move the handle to insert or remove a tape. A blinking green light
indicates a cartridge load fault. You can also move the handle when the

3—-10

MicroVAX 3500 VAXserver 3500 Operation

When you insert a write-protected cartridge into the drive, the orange indicator
light comes on. The system recognizes the tape as being write-protected under
any one of the following conditions:

The write pratect switch on the cartridge is set to the write-protect
position.

An operating system command has write-protected the tape.

A tape recorded on a TK50 tape drive is inserted into the drive.

Removing write-protection depends on how the tape was recorded and how
it is write-protected. You cannot write-enable a tape recorded on a TK50 tape
drive either by moving the write-protect switch on the cartridge or by using
software commands. The TK70 drive always recognizes a tape recorded on
a TK50 drive as write-protected. You can remove write-protection on tapes
recorded on a TK70 drive as follows:

If the cartridge is write-protected only by the write-protect switch on
the cartridge and not the operating system, moving the switch to the
write-enabled position causes the orange light to go out at the end of the
executing command.

If the cartridge is write-protected only by a software command and not
the write-protect switch, removing the operating system restriction causes
the orange light to go out.

If the cartridge is write-protected by both the switch on the cartridge and
a software command, you must change the switch setting and remove
the operating system restriction.

When you use a COMPACTape II cartridge to make a backup copy of files,
make sure the orange write-protect light on the TK70 drive is off. If the
light is not off, check for any of the write-protect conditions described above.
Change the switch setting and/or operating system restriction as necessary.
Do not begin your operation until the orange light goes off.

3.1.2.4 Tape Cartridge Handling and Storage Guidelines
e

Do not touch the exposed surface of the tape.

Do not drop the tape cartridge. The impact from a fall can damage the
tape cartridge.

Allow new tapes to stabilize at room temperature for 24 hours before
using them.

Using System Options

3-—11

Place an identification label only in the label slot on the front of the tape

cartridge.

®
*

Store tape cartridges in a dust-free environment.
Keep tape cartridges away from direct sunlight, heaters, and other sources

of heat.

Store tape cartridges in a stable temperature between 10° and
40° Celsius (50° and 104° Fahrenheit).

Store tape cartridges where the relative humidity is between 20 and
80
percent.

Keep tape cartridges away from magnets and equipment that generate
fields, such as motors, transformers, terminals, and audio

magnetic

equipment.

Keep tape cartridges away from x-ray equipment.

3.1.2.5 Inserting a Tape Cartridge
Before you use the tape drive, make sure the system is turned on (the power

switch glows). During power-up, the TK70 drive runs self-tests that last a few

seconds. All three lights (orange, yellow, and green) come on momentarily,
then the yellow light blinks during the self-tests. At the end of the tests, the
yellow light goes off and the green light comes on, accompanied by a short

beep. The green light and the beep indicate that you can move the cartridge

release handle.

CAUTION: Move the handle only when the green indicator light is on. Moving
the handle while the yellow light is on could damage the drive. If all three lights
blink rapidly at any time, a fault condition exists. Press the Unload button once.
If the fault is cleared, the tape unloads. The yellow light blinks during unloading,
then the green light comes on. If the fault is not cleared, the three lights continue
to flash. Do not attempt to use the tape drive or to remove the tape cartridge.

Call your DIGITAL service representative.

Use the following procedure to insert a tape cartridge (see Figure 3-6):
1.

Pull the handle open.

Position the cartridge so the arrow on the cartridge faces left and points
toward the drive. Insert the cartridge into the TK70 tape drive until you

feel the cartridge lock into place.
3.

Push the handle closed.

The green light goes off and the yellow light blinks as the tape loads.
When the yellow light glows steadily, the tape is ready to use.

controller, check the following:
Make sure the peripheral device is properly connected to the system.
Make sure the peripheral device is properly installed, plugged into an
appropriate power source, and turned on.

Make sure the peripheral device is properly set up.
Set-up involves
choosing how the device operates. Some set-up choices are matters of
personal choice; for example, the number of columns that display on a
terminal screen. Others, like baud rate (a measure of the speed at which

data is transmitted over a data line), must match the system setting if the
peripheral device and system are to communicate.
You choose set-up options from a series of menus that display when you
press the

key on the terminal keyboard. Set-up instructions for
terminals vary according to model, or, in some cases, according to which

read-only memory (ROM) cartridge is installed in your terminal. Be sure
to read the documentation provided with your terminal.
While most default settings are acceptable, you should perform the setup procedure for your terminal to ensure appropriate set-up values. The

3.2.3 Network Controllers
Before using a network controller you must do the following:
1.

Make sure the transceiver cable connected to the DELQA module in the
system is properly connected to the network in one of the following
ways:

To an H4000 transceiver located on a traditional Ethernet

To a DELNI, which can be connected to a larger Ethernet or which
can serve to connect up to eight systems in a local area network

To a DESTA, an adapter that enables you to connect to a ThinWire

Ethernet
2.
3.

Have the DECnet application installed on your system.
Register your node with the network manager so that your node is

recognized by other systems in the network.

Some software products, for example, Local Area VAXcluster (LAVc) software,

use the Ethernet hardware address of other systems to operate properly.
To find the hardware address of your Ethernet device, use the command

SHOW ETHER from console I/O mode.

The hardware address of your

Ethernet device displays on the terminal, as shown in the following example:
>>>SHOW ETHER
