Read the terminal owner’s manual to learn how to turn on and operate
the terminal. Before you connect the console terminal to your MicroVAX II
system, turn on the terminal to make sure it works correctly and to perform
some set-up operations.

The terminal performs a self-test every time you turn it on. The terminal
owner’s manual describes a successful self-test and possible error messages

that display if the terminal is not operating properly. Once the terminal

passes the test, you should perform some set-up operations.

Set-up involves choosing how your terminal operates. You choose set-up

options from a series of menus that display when you press the [Set-Up] key on

the terminal keyboard. Details about how to perform set-up and the set-up
options available on your terminal are in your terminal owner’s manual.
While most default settings are acceptable, you should perform the foliowing
procedure to ensure appropriate set-up values.

1. Press

to display the Set-Up Directory Screen. Choose the Default

option. Default correctly sets all values except line speed.

Choose the Comm option to display the Communications Set-Up Menu.
Choose the Transmit option and change the speed to 9600. Set Receive
equal to Transmit.

3. Choose the Return to Set-Up Directory option. Choose the Save Set-Up
option to store the set-up values.

Once you have tested your console terminal and performed set-up operations,
you are ready to connect the terminal to your MicroVAX II system.

chassis called a BA23 enclosure. Systems installed in a pedestal mount are
called 630QY systems. Systems installedin a rack are called 630QZ systems.
The illustrations in this manual show a pedestal-mounted system.

Rack-mounted systems differ from pedestal-mounted systems in two ways.
The rear panel is not attached, easing access to some controls, and the unit is
mounted horizontally. In descriptions of the system, references to up become
right and references to down become left. The different orientation primarily
affects operation of the TK50 and TK70 tape drives.

Descriptions and illustrations in this manual assume the system has mass
storage devices. If your system is a satellite node on a VAXcluster (a group
of computers networked together under the control of a server node), it may
be diskless. Diskless systems boot all software over the network from the
server node and store all data on mass storage devices on the server node.
Instructions specific to diskless systems occur periodically throughout this
manual. Consult your VAXcluster software documentation for more details
on using your satellite node.

This chapter introduces you to the system components and their functions.

The chapter describes the front and back of the system and the functions of
system components. Chapters 2 and 3 describe how to use the system and
installed options.

System Overview

1.1

Front Panel of the Pedestal Mount

The front of the system has a control panel and mass storage devices, unless
the system is diskless.

All illustrations in this manual show systems with

mass storage devices. Systems with mass storage have a fixed-disk drive and

one of the following: an RX50 diskette drive, an RX33 diskette drive, a TK50
tape drive, or a TK70 tape drive.
Figure 1-1 shows the front of the pedestal mount equipped with a TK50 tape

1.1.2 Mass Storage Devices
Your system has two types of mass storage: removable and fixed. The
removable type may be an RX50 diskette drive, an RX33 diskette drive, a
TK50 tape drive, or a TK70 tape drive. Either is installed just below the
control panel. Most illustrations in this manual show a system with an RX50
diskette drive installed. The system’s fixed-disk drive is behind the panel,
below the diskette drive or tape drive.

Controls for the fixed-disk drive are on the control panel described earlier in
this chapter. Controls and indicators for the diskette drives and tape drives
are described in the sections on those devices in Chapter 3.

1.2 Rear View of the Pedestal Mount
When you remove the rear panel of the system, you have access to controls
on the CPU panel and connectors for peripheral devices.

1.2.1 Controls on the CPU Panel
Figure 1-3 shows the controls on the CPU panel.
The CPU panel has the following components:

Halt Enable/Disable switch—When the switch is set to the left (dot
outside circle), halt is disabled. When the switch is set to the right (dot
inside the circle), halt is enabled. When halt is enabled, pressing the
key on the console terminal
Halt button on the control panel or the

1.3 Functionai Description of Base System

Components
Each MicroVAX II 630QY, 630QZ system includes base system components

common to all systems, and perhaps optional components. Your system was

preconfigured at the factory, based on your order.
The following sections describe base system components and options in turn.

System Overview

1-7

1.3.1

Base System Components

Base system components include the following:

Central processing unit (CPU)

Console serial line unit (SLU)

°*

Main memory

Mass storage devices and controllers (except for diskless systems)

Power supply

Fans

1.3.1.1 Central Processing Unit (CPU)
The central processing unit (CPU) controls the execution of all instructions and
processes.

Its circuits contain all the logic, arithmetic, and control functions

used by the system, as well as 1 Mbyte of main memory.

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

CPU module. The SLU connector is located on the CPU panel. The console
serial line provides a means of communicating with the CPU.

1.3.1.3 Main Memory
Main memory provides the physical storage area for all data and instructions
used by the CPU. When you start your system, the operating system is
loaded into main memory. Any 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. A large main memory
increases the efficiency of processing, as fewer pages must be copied to and

from the 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. You use mass storage devices, such as fixed

disks and tape cartridges, to store software and data permanently.

1-8

MicroVAX I 630QY, 6300Z

Operation

1.3.1.4 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 it. You 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.

A diskless system does not have its own mass storage devices, but uses the
mass storage devices on the server.

The two primary types of mass storage devices are fixed-disk drives and
devices with removable media, such as diskettes and tape cartridges.
Fixed-Disk Drives

One fixed-disk drive is permanently installed in your system, A fixed-disk
drive provides large-capacity storage for software and data files, as well as

rapid access to the data by the CPU.

Chapter 3 describes how to use the fixed-disk drive on your system.
Devices with Removable Media

The MicroVAX II 630QY, 630QZ system can have one diskette drive (either
an RX33 or an RX50) and cone tape drive (either a TK50 or a TK70). You
can use any of these devices as an input or output device. You use a device
as an input device when you install software or copy data from a diskette or
tape cartridge to your system. You use a device as an output device when
you copy software or data from your system to a diskette or tape cartridge.
You can copy individual files or programs, or you can copy (back up) the
contents of an entire fixed disk. Your system software manuals explain how
Mass Storage Controllers

All mass storage devices require a controller, a separate module that controls
all activity between the CPU and the mass storage devices. The controller for
the fixed-disk drives and the diskette drives (the RQDX3) and the controller
for the TK50 or TK70 tape drive (the TQK50 or TQK70, respectively) are
installed in the card cage.

System Overview

1.3.1.5 Power Supply
The system has a power supply that powers all system components. When
the power supply is generating the proper voltage, the DC OK light on the
front control panel glows green.

1.3.1.6 Fans
Two fans inside the BA23 enclosure draw in air from the bottom of the

system and pull it up through the modules and out the top, as shown in
Figure 1-5. To reduce the load on the fans, keep the system away from

heat sources and provide space for ventilation.

Operation

1.3.2 Optional Components
System options can include multiples of components that are part of the base

system (for example, additional memory modules) and the following kinds
of options:
e

Communications controllers

Real-time controllers

Printer interfaces

1.3.2.1 Communications Controllers
Every system has a serial line (a line on which each bit of information is sent

sequentially on a single channel) connecting the console terminal to the central
processing unit (CPU) module. Most systems have additional communications
controilers for connecting additional terminais 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

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.

Asynchronous Serial Controllers
Asynchronous

low-speed

connections between

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 asynchronous serial controllers without modem support to connect
additional terminals and printers to your system.

NOTE: Printers equipped with a microprocessor (intelligent printers) may require
modem control signals to function correctly.

Do not attach a printer requiring

System Overview

modem control signals to a controller with no modem support. Check your printer
documentation to determine the proper communications interface for your printer.
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 ends 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.

While all modems have the same basic function, some have more advanced
features, such as auto-answer.

These advanced features require additional

modem control signals. The difference between limited and full modem
support depends on the number of modem control signals recognized by
the communications device.

Full modem support (according to DIGITAL

standards) requires recognition of eleven signals.

Synchronous Serial Controllers
Synchronous serial controllers provide a high-speed connection 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.

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

1.3.2.2 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.

1-12

MicroVAX il 630QY, 6300Z

Operation

1.3.2.3 Printer Interfaces

Some printers require specific interfaces to communicate with the system.
For example, the LP25/26/27 printers and the LG01/02 printers require the
LPV11 interface.

1.3.2.4 Other Available Options

Your system arrives preconfigured with the options you ordered. As your
needs change, you can add more options. Your DIGITAL salesperson can
advise you on available options.
MicroVAX II 630QY, 630QZ Technical

630QZ systems. DIGITAL Field Service provides option installation.

System Overview

1-13

Chapter 2

Using the System
The first section of this chapter describes procedures appropriate only to new
systems.

The remainder of the chapter describes how to use your system

once the system software has been correctly installed.

2.1

Before You Use a New System

This chapter

assumes

that your system has been properly installed

described in MicroVAX II 630QY, 630QZ Installation.
System software and diagnostic software can be on either RX50 diskettes or
TK50-format tape cartridges. If your system has an RX33 diskette drive, you

can use the RX50 diskettes. Before running diagnostic software or installing
system software, you should read Section 3.1.2.1 (RX50), 3.1.2.2 (RX33),

3.1.3.1 (TK70), or 3.1.3.2 (TK50) on how to operate the appropriate drive.
If

a DIGITAL service representative installed your system, he or she ran

the diagnostic software shipped with your system. If you installed your own

system, you may want to run the diagnostic software before you install system
software. See MicroVAX II 630QY, 630QZ Troubleshooting for instructions.
After running the diagnostic software, install system software.

Follow the

instructions provided in the system software installation manual.

Some of

the instructions may require you to remove the rear panel to change switch
settings on the CPU panel.

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.

Using the System

2-1

2.2.1

Normal Operation

Switch settings for normal operation are the following:
The Halt Enable/Disable switch on the CPU panel is set to disable (left).
Once system software is installed, DIGITAL recommends you run your
system with halt disabled to prevent the user of the console terminal from
inadvertently halting the system by pressing

the front control panel.

or the Halt button on

Halting the system causes all activity to stop.

With halt disabled, your system automatically boots system software
when powered up.
The Power-Up Mode switch on the CPU panel is set to Run (indicated

by an arrow).
The baud rate switch on the CPU panel is set to 9600.
The Write-Protect button for the fixed-disk drive is set to out (not lit).
This setting allows system software to write to the disk.

The Ready button for the fixed-disk drive is set to out (glows green when
the disk is not being used).

This setting makes the drive available for

use.

The Halt button is set to out (not lit).

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

When you install system software and perform certain types of backups,
your system software manuals may tell you to set the Halt Enable/Disable

switch to enable (right).

If your system has been powered off for more than 10 days, the battery
unit that saves the system clock and the language selection may have
run down.

Set the Power-Up Mode switch to Language Inquiry Mode,

indicated by a human profile, before you turn on your system.

When

you turn on your system, a Language Selection Menu appears, as shown

in Figure 2-1.

Every time you turn on your system, it runs a series of self-tests. Your
console terminal displays a countdown from 7 to 3 as the system tests itself.

When the tests are successful, you receive the message “Tests completed.”
When your system detects an error during its self-tests, the countdown may
never start, may stop before reaching 3, or an error message may appear. See

MicroVAX II 630QY, 630QZ Troubleshooting for help in locating the problem.

2.4 Booting the System
You have the option of autobooting the system or booting from console mode.

The setting of the Halt Enable/Disable switch determines how the system

boots.

2.4.1 Autobooting the System
When the Halt Enable/Disable switch is set to disable (the normal operating
setting),

the system attempts to load system software after successfully

completing its self-tests.

If the system finds bootable system software, you

receive the messge “Loading system software”, and a countdown from 2 to 0

displays on the screen, as shown in Figure 2-2.

To load system software from console mode,

you must use the BOOT

command (BOOT device-name). For example, BOOT MUAUO telis the system

to boot software from a cartridge in the TK50 or TK70 tape drive. Software
manuals may instruct you to power up with halt enabled and to use the
BOOT command.

2.5 Using the System
Once the system software is loaded, the first display for the system software
appears on the console terminal after a few seconds. That display is described
in the system software documentation.

You are now ready to use the system. Refer to the system software manuals
and application manuals for more specific instructions on using the system.
Your system software manuals cover the following:

2.6 Turning Off the System
—r

o~
£~
Do not turn off your system uniess i requires maintenance or you know of
a planned power outage.

CAUTION: Turning off your system without following the shutdown procedure
described in your system software manuals may result in loss of data.
Once you have completed the recommended procedure, you can turn off

your system by setting the on/off switch to 0.

NOTE: Users of diskless systems in a VAXcluster should not turn off, hait, or
restart their sysiems without consulting the cluster manager. These activities
affect the functioning of the entire cluster.

2.7 Halting the System
Halting the system interrupts all processes and returns control to the console
program. You may need to halt the system during software installation. Or,
you may want to boot the system from another device, for example, a tape
cartridge containing MicroVAX diagnostic software.
To halt the system, first set the Halt Enable/Disable switch on the CPU panel
to enable (indicated by the dot inside the circle). To halt the system, press
in the Halt button on the control panel (glows red) or press the
key on

the console terminal. When the console mode prompt >>> appears on your
screen, the system is halted.

2.8 Restarting the System
Restarting the system aborts all current and pending operations and returns
the system to a power-on condition. The usual power-on tests are run. To
prevent loss of data, warn all users to log off prior to restarting the system.

You restart the system by pressing in the Restart button on the control panel.

use the fixed disk, you must set the Ready button to out (glows green when
the disk is available for use), the normal operating setting. When the Ready
button is out, the system can read from the fixed disk.

When the Write-

Protect button is also out, the system can write to the disk. The green light in

the Ready button indicates whether activity is occurring on the disk. When
the light is on, no activity is occurring and the disk is available for use. When
the light is off, activity is occurring.

If you want to automatically boot from another device, such as an RX50
diskette or a tape cartridge, you must set the Ready button to in (not lit).
When the Ready button is in, the system can neither read data from the
disk nor write data to the disk. (You can also use the BOOT command from
console mode to specify another boot device.)
The Write-Protect button controls whether the system can write data to the

fixed disk.

To write data to the disk, write-enable the disk by setting the

Write-Protect button to out (not lit). Your system disk must be write-enabled
for the system to function. Because the MicroVAX IT 630QY, 630QZ has only
one fixed-disk drive, you should never write-protect the disk.
The storage capacities and other specifications of the various disk drives in
the RD50 series are listed in MicroVAX II 630QY, 630QZ Technical Information.

3.1.2 Diskette Drives
The MicroVAX II 630QY, 630QZ can have either an RX50 diskette drive or

an RX33 diskette drive.

You can use RX50 diskettes in an RX33 diskette

drive, but the diskette capacity is reduced. You cannot use RX33 diskettes in

an RX50 diskette drive.

CAUTION: Inserting an RX33 diskette into an RX50 diskette drive can destroy
data on the diskette.

You can differentiate between the two types of diskettes by the color of
the plastic jacket:

the RX33 diskette is enclosed in a gray jacket; the RX50

diskette is enclosed in a black jacket.
You can use either diskette as both an input and output device.

Use the

diskette as an input device to load software or data into your system.

IT has a blue label strip. On the TK50 tape drive, the capacity is 95 Mbytes;
on the TK70 tape drive, the capacity is 296 Mbytes.

Once data has been recorded in a particular format (either TK50 format or
TK70 format), you can record over the data using the same type of drive.
For example, if you recorded data in TK50 format, you can record new data

on the tape if you use a TK50 drive.

You cannot record new data on the

The TK70 drive recognizes the TK50 format, and

write-protects the tape.

Similarly, you cannot use a TK50 to record over a
tape first recorded on a TK70 drive.

The TK70 drive can read tapes recorded on a TK50 drive.
Software is
distributed in the TK50 format and can be read by both TK50 and TK70
drive. The TK50 drive cannot read data recorded by a TK70.

Labeling the cartridges, write-protecting the cartridges, and handling and
storage guidelines are identical for COMPACTape and COMPACTape II tape

cartridges, regardless of the recording format.
The following subsections
discuss each of these procedures in turn.
The design and operation of
the two tape drives differ.
If your system has a TK70 tape drive, read

Section 3.1.3.1. If your system has a TK50 tape drive, read Section 3.1.3.2.

Labeling a Tape Cartridge
When recording data on a cartridge, label its contents. For your convenience,
a slot for the label is provided on the front of the cartridge.
Write the
identification on the label first, then insert the label in the slot on the front

of the cartridge, as shown in Figure 3-8. The label remains visible when the

tape is in the drive.

NOTE: Do not write on the tape cartridge or attach labels to the top, bottom,
or sides of the cartridge.
Write-Protecting a Tape Cartridge
Write-protecting a tape cartridge prevents accidental erasure of information
stored on the tape. You can write-protect a tape cartridge in two ways:

Set the write-protect switch on the cartridge to the write-protect position.

Write-protect the cartridge by using operating system commands described
in your system software manuals.

Using System Options

3—13

Your system can read information on the tape regardless of the position of
the write-protect switch or whether writing is software disabled.

However,

the system cannot write data to the tape when the write-protect switch is set

to the write-protect position, or when writing is software disabled.
When you use a cartridge to install software, make sure the cartridge is
write-protected.

To write-protect a cartridge, slide the write-protect switch

toward the label slot (see Figure 3-9). Two icons on the switch indicate the
write-protect status. When the tape is write-protected, an orange rectangle is

visible next to the lower icon.

If the cartridge is write-protected only by a software command and not the
write-protect switch, removing the operating system restriction removes
the write-protection. On the TK70 drive, the orange light goes 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.

NOTE: You cannot write-enable a tape recorded in TK50 format for a TK70
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.

When you use a tape cartridge to make a backup copy of files, make sure

the tape is write-enabled. On the TK70 drive the orange light should be 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.
Tape Cartridge Handling and Storage Guidelines
*

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.

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

Store tape cartridges in a dust-free environment.

Using System Options

3.1.3.1 TK70 Tape Drive
The TK70 tape drive holds one removable COMPACTape Il or COMPACTape
cartridge. You can use a COMPACTape II 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.

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
II or COMPACTape that has been written by a TK50 tape drive.

the leader in the cartridge, and the tape winds onto the take-up reel. The
coupling and winding process is called loading. When the automatic loading
process completes, the tape is ready to use.

Once the cartridge is loaded, you cannot remove it without rewinding and
uncoupling the leaders, a process called unloading. Even if you have not
used the tape, you must unload it before you can remove the cartridge. When
you press the Unload button, the tape rewinds into the cartridge and the
leaders uncouple.

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 while the TK70 drive runs 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 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 3-11.)

The TK50 tape drive holds one removable COMPACTape or COMPACTape
II cartridge. You can use either type of cartridge as both an input and output
device.

Use the tape cartridge as an input device to load software or data
into your system. Use the tape cartridge as an output device to make copies
(or backups) of software or data.

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

You use the Load/Unload button to control winding or rewinding of the
tape. The button is a 2-position control. When you press in the button, the
tape winds onto the take-up reel. When you press the button again, it pops
out and the tape rewinds back into the tape cartridge.

The drive also has two indicator lights that let you know the status of the
drive. A red light is part of the Load/Unload button. A green indicator light
is at the opposite end of the drive. Figure 3-13 shows the TK50 tape drive
with the controls and indicator lights labeled.

To operate the drive properly, you must carefully monitor the status lights.
The instructions for inserting and removing cartridges, which appear later
in this section, tell you exactly what should happen at each step. Table
3-3 and Table 3-4 at the end of this section summarize light and control

combinations.

Design of the Drive
The TK50 drive operates somewhat like a reel-to-reel tape deck. Inside the
drive is a take-up reel with a leader attached. Inside the cartridge is a single
reel containing the magnetic tape. When you insert the cartridge and press in

the Load/Unload button, the leader in the drive automatically couples with
the leader in the cartridge, and the tape winds onto the take-up reel. The
coupling and winding process is called loading. When the automatic loading
process completes, the cartridge is ready to use.

The method of coupling the two leaders is similar to threading a needle. The
leader in the cartridge has a large eye with a notch. The leader in the drive

is arrow-shaped. (See Figure 3-14.)

Loading occurs in two stages:
1.

nsert a cartridge, the lea er in the drive first threads through

oLl

(U913

the eye of the cartridge leader.
2.

When you press in the Load/Unload button, the take-up reel begins to
move and the drive leader catches in the notch, pulling the tape onto the
take-up reel.

Once the cartridge is loaded, you cannot remove it without rewinding and

uncoupling the leaders, a process called unloading.

Even if you have not

used the tape, you must unload it before you can remove the cartridge. When
you move the Load/Unload button to the out position, the tape rewinds into
the cartridge and the leaders uncouple.

Although rare, rough handling during shipment may dislodge either the
cartridge leader or the drive leader.

Because the position of each leader is

critical to successful coupling, you should make sure the leaders are properly
positioned.

Check the cartridge leader in the following situations:
*

When you use a cartridge for the first time. The cartridge could be blank
or could contain software.

After you drop a cartridge, since the shock can dislodge a leader.

Using System Options

When you have load/unload problems.

Check the tape drive leader in the following situations:
*

When you first install the system.

After you move the system.

When you have load/unload problems.

The following two sections explain how to check each leader.

Checking the Cartridge Leader
To check the cartridge leader, open the door in the back of the cartridge.
With your thumb, lift the door lock, as shown in Figure 3-15, and press on
the hinge. The door swings open. The tape leader should appear exactly as
shown in Figure 3-15, with most of the leader eye visible.

If no leader is visible or if the leader extends out more than is shown in
the figure, do not load the cartridge into your tape drive or try to adjust the
leader. Contact your DIGITAL service representative for another cartridge. If
the leader appears normal, close the cartridge door and proceed.

CAUTION: Using a cartridge with a mispositioned leader can damage the tape
drive.

3.2.2 Synchronous Controllers
Before using a synchronous controller you must verify the following:
The system you want to communicate with has an appropriate
synchronous controller.
Synchronous communications require a
synchronous controller on both the transmitting and receiving systems.
Both the transmitting and receiving systems must have supporting host
software installed. Synchronous communications operate under specific
protocols that define how data is interpreted. Two common protocols
are X.25 and PSI. Appropriate host software is required to interpret the
protocol.

1.

Make sure the transceiver cable connected to the DEQNA or 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.

Have the DECnet application installed on your system.

Refer to your system software manuals and DECnet manuals for other
requirements and further instructions on using a network connection.

the problem.

This manual is divided into three chapters:
®

Chapter 1 describes problems you may experience at power-up-and
corrective actions.

Chapter 2 describes problems you may have during normal operation of
your system and corrective actions.

Chapter

describes

the

MicroVAX

Diagnostic

Monitor

(MDM),

diagnostic tool you can use to test your system periodically or to isolate
a particular probiem.
The troubleshooting techniques described in this manual do not identify all

possible problems with your system, nor do the actions suggested remedy
all problems. If the actions suggested do not solve the problem, call your
DIGITAL service representative.

Chapter

Troubleshooting During Power-On
Whenever you power on your system, the MicroVAX II processor performs a

series of self-tests and start-up routines. After successful completion of the
self-tests, the system attempts to load system software. MicroVAX II 630QY,
630QZ Operation describes the display you see during the normal power-on
sequence.

A countdown from F (15 in hexadecimal numbers) to 0 occurs during the

normal sequence. Only the hexadecimal portion from 7 to 0 displays on the
console terminal screen.

The full countdown displays on the light emitting

diode (LED) on the central processing unit (CPU) panel.

The countdown

sequence has three major parts:

From F through 8, the system performs internal tests.

From 7 through 3, the system tests memory and the CPU.

From 2 through 0, the system loads system software.

When attempting to autoboot, the system looks for bootable software on the
following devices in the order shown below:
1.

RX50 diskette

RD50-series of fixed-disk drive

TK50/TK70 tape cartridge

Ethernet adapter

Normally, your system boots from system software installed on a fixed disk.
However, when you install system software or run diagnostic software, the
system boots from either an RX50 diskette or a tape cartridge.
NOTE: If you have a diskless system that is part of a local area network (LAN),
you must obtain the MicroVAX II Ethernet Server Customer Diagnostics Kit
to run the MicroVAX Diagnostic Monitor (MDM). Contact your DIGITAL sales
representative to order the MicroVAX II Ethernet Server Customer Diagnostics
Kit.

Troubleshooting During Power-On

If you have a diskless system that is not part of a LAN, you cannot run MDM.
Contact a DIGITAL service representative to diagnose problems on a diskless

system that is not part of a network.
If you do not observe this sequence, refer to the possible problems and
corrective actions described in Table 1-1.

Running the MicroVAX Diagnostic
Monitor (VIDM)
The MicroVAX Diagnostic Monitor (MDM) is a software package containing
diagnostic tests designed to isolate and identify faults in your system. The
diagnostic tests are packaged with your system on either RX50 diskettes
(labeled MV DIAG CUST RX50) or a TK50 tape cartridge (labeled MV DIAG
COTICT

CuUol

TEN

1RJV).

If you have a diskless system that is part of a local area network (LAN), you
must obtain the MicroVAX II Ethernet Server Customer Diagnostics Kit to
run MDM.

NOTE: If you have a diskless system that is not part of a LAN, you cannot run
MDM. Call your DIGITAL service representative.

The MicroVAX II Ethernet Server Customer Diagnostics Kit enables you to
install MDM software on a host VAX/VMS or MicroVMS operating system
and down-line load MDM to other systems that are part of the LAN using
the DECnet/Ethernet network facilities. When MDM is down-line loaded to
target systems from a host system, the time required to load MDM is reduced
significantly.

Call your DIGITAL sales representative to order the MicroVAX II Ethernet
Server Customer Diagnostics Kit.

WARNING: If your system is connected to a cluster, notify your cluster manager
before halting the system to load MDM.

You generally run MDM in three situations:

Before you install system software on a new system

When you receive an error message or experience a problem with your
system

When you want to test your system periodically to ensure that all
components are operating correctly

The customer system test has two parts: a functional part that individually
tests each device installed in your system and an exerciser part that tests how
the devices work together. The customer tests cannot check every device in
the system. For example, customer tests check the controller but not the disk
drive, as testing the drive requires writing to the disk and possibly destroying
data.

Nor can the customer tests check each device as thoroughly as the

service diagnostic tests.

The customer tests check only the devices in the system, not the connectors
or lines between peripheral devices and the system.

If devices pass the

customer tests but you still experience problems, contact a DIGITAL service
representative for further testing.

Before you run the MDM software:
®*

Be sure you understand the instructions in MicroVAX II 630QY, 630QZ

Operation for using the device appropriate for your diagnostic media —

either the RX50 diskette drive or the TK50/TK70 tape drive.
*

Make sure the media (tape cartridge or RX50 diskette) is write-protected.

3.1 Starting MDM
The diagnostic tests run the same way whether or not software has been
installed.

NOTE: Before booting MDM on a system with software installed, warn all users
to log off and perform system shutdown, as described in your system software

manuals.
You must start the diagnostic tests differently, depending on the media used.

If you are booting MDM from an RX50 diskette, read Section 3.1.1.

If you

are installing MDM from a tape cartridge, read Section 3.1.2.

NOTE: Unless instructed to do so, do not change any settings or manipulate
devices while the tests are running. The diagnostic software interprets any change
of state as an error.

3—-2

MicroVAX 1l 630QY, 630QZ Troubleshooting

3.1.1 RXb0 Instructions
Because the system automatically boots first from an RX50 diskette, you can
run MDM software the same way, whether or not the system software has
been installed on the system. To run diagnostic software from RX50 diskettes,
do the following:
»

Press the fixed disk 0 Ready button on the system control panel to the
/

out position.

Insert diskette RX50A into one of the drives (be careful to align the orange
arrow on the diskette with the orange stripe on the drive) and close the
door.

Press the Restart button if the system is running, or turn on the system
if the system is off.

A countdown from 7 through 3 should appear on the console terminal
as the system performs self-tests. The countdown continues from 2 to 0
as the system loads the diagnostic software.
At this point, you may be prompted to remove diskette RX50A and insert
the next diskette. Remove diskette RX50A and insert diskette RX50B.

Within a few moments you should see the MDM introductory display, as
shown in Figure 3-1.

As each device passes the test, it is listed on the screen, as shown in Figure

NOTE: Because of the internal similarity of some communications options, the
diagnostic test sees these options as the same device. A DHVII and DHQII
appear the same to the diagnostic test. A generic device name, DH-CXO0, is
listed for similar communications options. The last letter in each device name
differentiates among multiple devices of the same type. For example, DH-CX0A
indicates one communications option; DH-CXO0B a second, and so forth.
If a device fails the test, you receive a failure message, as shown in

At least two lines of information are provided for each device. The first
line lists the name of the device and gives a brief description. The second
line indicates the revision level of the device. The revision level can refer
to hardware or microcode. For example, the KDA50 controller described in
Figure 3-13 is at revision 5 for microcode (MCF5) and revision 3 for hardware
(HW=3).

Besides the general information listed for each device, additional information
for specific devices is listed as foliows:

CPU — type of CPU, presence of a floating-point unit (FPU)

MEM — total amount of memory in megabytes and pages, number and
type of memory modules

RQDX3 — type, unit number, and description of each mass storage device
supported by the controller

DELQA/DEQNA — the Ethernet station address

Running the MicroVAX Diagnostic Monitor (MDM}

3-17

Communications devices — the type of device and whether it has modem
control

In addition to showing information about testable device options, MDM
displays message indicating the presence of nontestable systems devices. If a
device is physically present in the system but is not listed under the System
Configuration and Devices display, one of the following two messages can

indicate the reason.

Message 1:
No Dg KAA

...

Message number %x00000000

The “No Dg” (no diagnostic) “KAA” (KA630 CPUA) message appears in place
of the device name because a diagnostic was not loaded for the CPUA. This
can happen when the media is not installed properly or the diagnostic is not
present on the media.
MDM displays a “No Dg” message for each DIGITAL device present in the

system under these circumstances. For example, an unloaded TK70 diagnostic
results in the message, “No Dg TKA.” TKA indicates that the device is a TK70.

Message 2:
Invld Dev

...

Message number %x00000000

The “Invld Dev” (invalid device) message indicates that a device not
recognizable to MDM has been attached to the system. The message appears
under the following circumstances:
*

A device is configured to a nonstandard CSR address.

ADIGITAL device that has no diagnostic has been attached to the system.
This may occur if a device not supported on a MicroVAX II system has

been attached.
*

A non-DIGITAL device has been attached to the system.

Preface
This book summarizes technical information about the MicroVAX II 630QY,

630QZ system. The book is organized as follows:
Chapter 1 describes the base system specifications, including the CPU
module and associated memory options.
Chapter 2 describes specifications for optional components available for

Chapter

Base System Specifications
The MicroVAX 1I 630QY, 630QZ base system includes a KA630 CPU module
and one or two MS630 memory modules in a BA23 enclosure. The MicroVAX
II CPU normally resides in slot 1 of the backplane. It may not be installed
TY

rANMN/

in slots 4-8. Memory options may reside in slots 2 and 3.

1.1 Base System Operation

Base system operation includes the KA630 firmware and the controls on the
CPU panel.

1.1.1 KA630 Firmware

Two read-only memory (ROM) chips on the KA630 module contain firmware.
The firmware contains three major programs:
¢

A console program

A set of self-tests for the CPU and memory

A primary bootstrap program (VMB)

The console program receives control whenever the processor halts. For the
KA630 CPU, a halt means only that processor control has passed to the
console program, not that instruction execution stops. The standard VAX
console functionality is emulated by executing a program in ROM, rather
than by CPU microcode or a separate processor.

Control passes to the firmware under any of the following conditions:

The system is powered up

The Restart button is pressed

The Q22-bus BHALT signal is asserted (typically by pressing the
key or the Halt button when the Halt Enable/Disable switch is set to
enable)

A halt instruction is executed

Base System Specifications

1—1

A system error occurs

At power-up, the system enters one of three power-up modes
that are set
using the Power-Up Mode switch on the CPU panel. (The
modes and their

meanings are described later in the chapter.)

The console program then

determines the console device type and console language

The console program then runs the self-tests for the CPU
message

and memory. The

Performing normal system tests

is displayed on the terminal. As the tests progress, a countdo
wn displays on
the console terminal and on a LED display on the CPU panel.
MicroVAX
IT 630QY, 630QZ Operation describes the power-on sequence
and shows

examples of successful power-on operations.

MicroVAX II 630QY, 630QZ
Troubleshooting describes possible problems that can occur
during power-on.

If the self-tests are successful, the system does one of

two things, depending
on whether the Halt Enable /Disable switch on the CPU
panel is set to disable
or enable.
If the Halt Enable/Disable switch is set to disable, the

CPU tries to load and
start (bootstrap) an operating system. It locates a 64-Kbyt
e segment of system

memory and copies a primary bootstrap program,

called VMB, from the ROM

chip into the base address plus 512. The CPU then begins
executing VMB,
which attempts to bootstrap an operating system from
one of the devices in
Table 1-1 in the order shown.

Im = Mscp controller designator (A = first, B = second etc.)

n = unit number

When VMB determines that a controller is present,
it searches in order of
increasing unit number for a bootable unit with
a removable volume, then
proceeds to the next controller. If it finds none,
it will repeat the search for
a nonremovable volume.

MicroVAX 1l 630QY, 63007 Technical Information

If halt is enabled, the console program enters console I/O mode in response
to any halt condition, including system power-up. Console I/O mode allows
you to control the system by typing commands at the console terminal.

You can direct the system to boot a specific device when in console I/O
mode. Use the BOOT command, followed by the device name as listed in
Table 1-1. For example, to boot from the TK50 tape drive you would issue
the command: BOOT MUAO.

1.1.2 CPU Panel Operation
The CPU panel (accessible only after removing the back cover) contains the
following components, as shown in Figure 1-1.
*

Three switches

One LED display

One external connector for the console terminal serial line unit (SLU)

One battery backup unit (BBU) for the time-of-year clock and language

1.1.2.2 LED Display

The LED display on the CPU panel displays a countdown sequence as the
system runs its self-test diagnostics and bootstrap routine. The countdown
begins with F (15 in decimal) to 0. (The same display appears on the console
terminal beginning with 7.) See MicroVAX II 630QY, 630QZ Operation for
examples of successful power-on sequences, and MicroVAX II 630QY, 630QZ
Troubleshooting for examples of problems you may encounter during poweron.

1.1.2.3 Console Terminal Connector

The console cable is connected to the CPU panel as shown in Figure 1-1.
1.1.2.4 Battery Backup Unit (BBU)
A battery backup unit (BBU), located on the inside of the CPU panel, provides
power for maintaining the correct time-of-year and language selection when

power to the system is turned off.

Both the time-of-year and language

selection code are lost if the BBU fails.

The BBU provides power for up to

ten days if the system power is turned off.
