Preface
This manual describes how to use MicroVAX 3800 and VAXserver 3800
systems. The hardware and software for each of these systems differs
slightly, according to the function of the system. The MicroVAX 3800 is
a multiuser system that uses the VMS, ULTRIX or VAXELN operating
systems, and functions as an end- or full-function node on an Ethernet
network. VAXserver systems are single-user systems that use either VMS
or ULTRIX operating systems. VAXserver systems that use VMS are
DECnet full-function network nodes; systems that use ULTRIX are DECnet
end-function nodes.
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.

•

Appendix A lists related documentation.

•

Appendix B provides instruction on reprogramming the KFQSA module.

•

A glossary explains key terms.

NOTE: VAXserver 3800 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

Up to three RF71 Integrated Storage Elements (lSEs) can be mounted
inside the BA213 enclosure.
This chapter describes the MicroVAX 3800 and VAXserver 3800 system
components and their functions. 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.

1.1 Front View and Physical Description
The front of the system has a removable front panel that restricts access
to some of the system controls.
Figure 1-1 shows the system with the front panel attached.

System Overview 1-1

Figure 1-1: MicroVAXlVAXserver 3800 System

The front panel has a sliding window controlled by a three-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.

a two-position button. When you press in the button, the system halts
and the console mode prompt »> displays 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 IReturnf' to continue. Chapter 2
describes halting the system in more detail.
CAUTION: Pressing in the Halt button halts the system regardless of the
setting of the Break Enable / Disable switch on the CPU cover panel.

To the left of the Halt button is the Restart button. When you press the
Restart button, the system reboots system software. Further instructions
on restarting your system are in Chapter 2.

MLO-002286

The number and type of modules installed in your system depend on your
configuration. Each slot, even an empty one, is protected by a module
cover panel. Together the panels form a shield with a three-fold purpose:
to protect external devices from electrical interference generated by the
system; to protect the system from electrical interference generated by
external devices; and to maintain air flow integrity_
CAUTION: Do not operate the system without DIGITAL-supplied module
cover panels. The cover panels are required to protect the equipment and
to meet international regulatory standards. Do not substitute other module
cover panels as they may not meet the required specifications.

System Overview 1-13

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.

The design of the cover panels varies, depending on the type of module
installed in the slot. Modules requiring external cable connections, such
as communications controllers 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 or side 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. Additional
memory modules may be installed in slots 2 through 4. 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.

The CPU cover panel has the following components:
•

Break EnablelDisable 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 IBreak Ion
the console terminal halts the processor and transfers control to the
console program.

System Overview

1-15

•

Power-Up Mode switch - This three-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.
Also, if a default boot device has not been selected, this mode causes
the system to issue a list of bootable devices and prompts you to
select a device from the list. Once a device is selected, the system
autoboots from that device each time you turn it on.
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 specialloopback connectors
and is for DIGITAL Field Service use only.

•

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

•

Modified modular jack (MMJ) - This console terminal connector,
labeled AI, provides the connection for the console terminal.

1.1.1.3 Power Supplies

Your system has two power supplies. The right power supply provides
power to modules installed in slots 1-6, one or two mass storage devices
(the TK70 tape drive and one RF71 ISE), and the two fans. The left power
supply provides power to modules installed in slots 7-12 and a second or
third RF71 ISE, if present. Figure 1-12 shows the controls and indicators
on each power supply.

The controls and indicator lights function as follows:
•

DC OK - When the DC OK light is lit, the voltages are within the
correct operating range. An unlit DC OK light indicates a problem
with the power supply. Tum off the system and call your DIGITAL
service representative.

•

Reset button- A recessed Reset button enables you to reset the system
to a power-on state without turning it off. The Reset button is recessed
to prevent you from inadvertently resetting the system. Use your
fingertip or a small tool to press the button. See Chapter 2 for the
correct procedures for resetting the system.

•

Circuit breaker - The circuit breaker trips to protect the system from
power surges. When tripped, the circuit breaker is in the out position.
To reset the breaker, press the circuit breaker to the in position.

1.1.1.4 Fans

Two fans located under the card cage draw air in through the top of the
enclosure, down through the card cage, 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. Figure 1-13
shows the air flow through the system enclosure.

1.2 Functional Description of Base System
Each MicroVAX 3800 and VAXserver 3800 system includes base system
components common to all systems. Your system may have optional
components as well. Your system was configured at the factory, based on
your order.
The following sections describe base system components and options in
turn.

1-18 MicroVAX 3800 VAXserver 3800 Operation

1.2.1 Base System Components
Base system components include the following:
•

Central processing unit (CPU)

•

Console serial line unit (SLU)

•

Main memory

•

Network controller

•

Mass storage devices and controllers

1.2.1.1 Central Processing Unit (CPU)

The central processing unit (CPU) controls the execution of all instructions
and processes. The CPU circuits contain the logic, arithmetic, and control
functions used by the system.
1.2.1.2 Console Serial Line Unit (SLU)

Each system has a serial line unit connecting the console terminal to the
CPU module. The SLU connector (a modified modular jack) is located
on the CPU cover panel. The console serial line provides a means of
communicating with the CPU.
1.2.1.3 Main Memory

Main memory provides the electrical storage area for data and instructions
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. A large main
memory increases the efficiency of processing, since fewer pages must be
copied to and from the disk. Each configuration comes with a standard
memory option that you can add 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 Network Controller

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. Your system comes with the DESQA

System Overview 1-19

Ethernet controller, which allows you to connect to either standard Ethernet
cable or to ThinWire Ethernet cable.
1.2.1.5 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 transfers it
from the mass storage device into main memory. The two primary types
of mass storage devices are the RF -series integrated storage elements and
devices with removable media, such as tape cartridges, and compact disks.
Integrated Storage Elements

Up to three RF-series integrated storage elements are installed in your
system. An integrated storage element is an intelligent storage device that
contains its own controller.
Devices with Removable Media

Devices with removable media, such as tape cartridges are used as both
input and output devices. In addition, compact optical disks are used
as input devices when you install software or copy data to your system.
Tape cartridges are the primary media for loading software. You use tape
cartridges and tapes 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 are commonly
used to archive data.
Mass Storage Controllers

All mass storage devices require a controller, a device that controls activity
between the CPU and the mass storage devices. The controller for the
TK70 tape drive is the TQK70. The controller for each RF71 ISE is builtin to the storage element. The CPU communicates with the ISEs through
an adapter module, the KFQSA. The TQK70 and the KFQSA modules are
installed to the left of other modules in the card cage.

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 ISEs) and the
following kinds of options:
•

Mass storage subsystems

•

Communications controllers

1-20

MicroVAX 3800 VAXs~rver 3800 Operation

•

Real-time controllers

•

Printer interfaces

1.2.2.1 Mass Storage Subsystems

Several optional mass storage subsystems are available for MicroVAX and
VAXserver 3800 systems. Such subsystems include RRD40/50 Digital Disk
Subsystems, the RV20 Optical Disk Subsystem, and TS05 and TU81 tape
drives. If your system includes an optional mass storage subsystem, refer
to the user's guide or owner's manual for that subsystem for instructions
on how to operate the device.
1.2.2.2 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.
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.

System Overview

1-21

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

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. At the receiving end, another modem converts
the analog signals back into digital signals the computer can process.
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.
DECservers

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

1-22 MicroVAX 3800 VAXserver 3800 Operation

editing and printing on remote systems; and share resources, such as laser
printers.
1.2.2.3 Real-Time Controllers

Real-time controllers interface with devices that monitor or control
particular processes, for example, laboratory equipment or manufacturing
equipment connected to the system. Typically, real-time controllers are
parallel devices, not serial devices.
.
1.2.2.4 Printer Interfaces

Some printers require specific interfaces to communicate with the system.
For example, the LGOl, LG02, LP25-LP29 printers require the LPVll-SA
interface.
1.2.2.5 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. Micro VAX 3800/3900 VAXserver
3800/3900 Technical Information describes the options currently available
for MicroVAX and VAXserver 3800 systems. DIGITAL provides installation
for additional options that you order.

1.3 Dual-Host Capability (VMS Systems Only)
CAUTION: Before building a dual-host configuration, consult your
DIGITAL service representative and reference your system warranty. The
terms of your warranty may be violated if you attempt to configure these
systems yourself

If there is a TK tape drive in each system, a DIGITAL service representative
must set the unit number on one of the TQK controllers to 1. This will
provide each tape drive with a unique device name.
A dual-host MicroVAX system consists of two MicroVAX systems in
the same VAXcluster sharing their ISEs via a Digital Storage System
Interconnect (DSSI) bus. Each system can have direct access to any of
the ISEs in either system; this can include a shared common system disk.
The primary application for such a configuration is a VAXcluster system.
The simplest dual-host configuration, for example, is to configure one
system disk to be used as the system disk by both systems. The system
disk physically resides in one enclosure, however, both systems have equal
access to the system disk and to any other DSSI mass storage device in
either enclosure.

System Overview

1-23

A Digital Storage System Interconnect (DSSI) storage element, such as the
RF71, has a built-in multihost capability that allows it to connect to more
than one DSSI host adapter. Since the DSSI host adapter, the KFQSA in
this case, is located in the card cage of the MicroVAX 3800 system, two
MicroVAX 3800 systems can be connected to the same DSSI bus.
NOTE: Systems that use the KFQSA host adapter module can only form a
dual-host configuration with other KFQSA-based systems. For example, a
Micro VAX 3800 (host adapter is the KFQSA module) cannot form a dualhost configuration with a MicroVAX 3400 (host adapter is on the KA640
CPU module).

Using an external DSSI cable, any two KFQSA-based systems (MicroVAX
3800, VAXserver 3800, and those MicroVAXlVAXserver 3500 systems with
the KFQSA module) can be connected to form a dual-host configuration.
Figure 1-14 shows a possible dual-host configuration.
NOTE: Dual-host capability is only supported under VMS (version 5.1-1
and later) when the two systems are configured into the same Local Area
VAXcluster (LAVC).

The benefits of a KFQSA-based dual-host configuration are:
•

VAXcluster features such as shared data across systems and satellite
nodes.

•

Higher system availability - If one of the KFQSA-based systems is
unavailable, for example, due to a system malfunction, the satellites
booted through it are able to continue operating through the other
KFQSA-based system. This process is described in detail in the
following paragraphs.

If one of the KFQSA-based systems fails, all satellite nodes booted through
that system lose connections to the system disk. Each satellite node knows,
however, that the system disk is also available through a second path. The
satellite nodes establish a new connection through the other system and
continue operation.
To increase system availability, more redundancy may be added to a
configuration. This can be done in a dual-host configuration by using two
system disks (one for each boot node). In the event of one system disk
failure, the remaining system disk would continue to serve one KFQSAbased system and the satellite nodes booted through it. As with any
VAXcluster, however, a second system disk improves availability while
increasing system management tasks.

Figure 1-14:

KFQSA-Based Dual-Host Configuration

MLO-002290

To build a dual-host configuration, perform the following steps:
1. Form a VAXcluster configuration. If your systems are not already
clustered, you must cluster them. For more information, refer to the
VMS VAXcluster manual that is part of the VMS documentation. If
this manual is not available, contact your DIGITAL representative.

2. Reprogram the KFQSA configuration table and set each ISE's
parameter to a nonzero allocation class to match that of the two host
systems. Consult your DIGITAL service representative or follow the
instructions provided in Appendix B.

System Overview

1-25

3. Change the Unit I.D. plugs that identify the ISEs to the system.
(Supplemental Unit I.D. plugs are included with your system.) When
two systems are connected together, one system's RF71s must be
renumbered, using different Unit I.D. plugs. (Each ISE must have its
own node number. The node numbers start at 0 and may continue
through 5. The ISEs should be numbered consecutively without
skipping a node number.) For instructions on how to change a Unit
I.D. plug, refer to Appendix B and the section on RF71 ISEs in Chapter
3 of this manual.

NOTE: The DSSI bus supports eight devices / adapters. With two
KFQSA adapters, the dual-host configuration supports a maximum of
six DSSI devices.
4. Obtain an .external DSSI cable which connects the two system
enclosures. Order this cable through your DIGITAL representative.

NOTE: If you have ordered a tapeless MicroVAX or VAXserver 3800
system, an external DSSI cable is included with your system shipment.
The power should be off when you attach the DSSI cable.
To attach the DSSI cable, feed the ends of the cables under the hosts
from the back or side. Plug the cable into the DSSI ports by fitting
the cable connectors over the two pins on each DSSI port as shown in
Figure 1-14.
First tighten the connections by hand, then use the screwdriver shipped
with your system to firmly secure the connection.

NOTE: If you need to remove the DSSI cable, loosen the screws at the
connector, and carefully remove the cable by pulling the cable straight
out by the two screw heads simultaneously.

Chapter 2

Operating the System
This chapter describes how to operate your MicroVAX once the system
software has been installed.

2.1 Before You Operate the System
This chapter assumes that your system has been properly installed.
Installation includes running the diagnostic software shipped with your
system and installing the base operating 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 on the CPU cover 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.
Set the switches according to your needs.

2.2.1 Normal Operation
Switch settings for normal operation are the following:
•

The Break EnablelDisable switch on the CPU cover panel is set
to disable (down). Once system software is installed, DIGITAL
recommends you run the system with halt disabled to prevent the
user from inadvertently halting the system by pressing iBreaki on the
console terminal. Halting the system causes all activity to stop. With
halt disabled, the system automatically boots system software when
powered up.

•

The Power-Up Mode switch on the CPU cover panel is set to Run
(indicated by an arrow).

•

The baud rate switch on the CPU cover panel is set to 9600.

Operating the System

2-1

•

The Write-Protect button for each RF71 ISE is set to out (not lit). This
setting allows system software to write to the storage element.

•

The Ready button for each RF71 ISE is set to out (glows green when
the storage element is not being used). This setting makes the storage
element available for use.

•

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

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, set the Break EnablelDisable switch to enable (up). This
allows you to halt the system by pressing IBreakl on the console terminal.

•

If you want data on a particular ISE to be write-protected, you must
set the Write-Protect switch to in (glows).
NOTE: ISEs containing system software and user accounts must remain

write-enabled. ISEs containing applications or sensitive data may be
write-protected.
•

If you want to use the Language Selection Menu to select a new
language for the console program, before you turn on your system, set
the Power-Up Mode switch to Language Inquiry Mode. A human profile
indicates the language inquiry mode. When you turn on your system,
a Language Selection Menu appears, as shown in Figure 2-1.

Ifthe Power-Up Mode switch is set to Run Mode (indicated by an arrow),
then the language selected is saved and is automatically used during
subsequent reboots of the system.
NOTE: If the Power-Up Mode switch is set to Language Inquiry Mode
(indicated by the human profile), the system will prompt for the language
at each power-up.

In addition to the Language Selection Menu, the system may issue a
list of bootable devices and prompt you to select a device from the list.
If this happens, refer to Section 2.4.1 for more information.
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. The Language Selection Menu will automatically display
when you power up your system, regardless of the Power-Up Mode
switch setting. Once the system is booted, reset the system clock, as
described in your system software manual.

2.3 Turning On the System
Once you have set the switches correctly, you are ready to turn on the
system. Use the following procedure:
1. Tum on the console terminal and wait for it to complete its self-tests.
2. Turn on the system by setting the on/off switch to 1.

When you tum on the power, you should see the indications listed in Table
2-1.

If you do not observe the indications in Table 2-1, refer to MicroVAX
Troubleshooting and Diagnostics.
Every time you tum on your system, it runs a series of self-tests on the
CPU and memory. Your console terminal first displays a line of information
identifying the CPU, the version of the firmware, and the version ofVMBthe primary bootstrap program. In the sample screen shown in Figure 2-2,
the CPU is identified as a KA655-A, the version of the firmware is V5.3,
and the version of VMB is 2.7. 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
Sections 2.4.1 and 2.4.2.
When your system detects an error during its self-tests, it displays an error
summary consisting of several lines of hexadecimal numbers. A DIGITAL
service representative can use the error summary to diagnose the system.

2-4 MicroVAX 3800 VAXserver 3800 Operation

Depending on the type of error, one or more error summaries may display
on the console terminal. A sample error summary is shown in Figure 2-2.

2.4 Booting the System
MicroVAX and VAXserver 3800 systems boot in one of two ways. You can
configure the system to autoboot on power-up or you can manually boot
the system from console mode. The Break EnablelDisable switch setting
determines how the system boots.

2.4.1 Autobooting the System
When the Break EnablelDisable switch is set to disable (the normal
operating setting), the system runs self-tests and, on completion, attempts
to load system software.
Depending on whether or not a boot device has been selected, the system
loads system software or prompts you to select a boot device.
Loading System Software (When a Boot Device Has Been Selected)

When a boot device has been selected, the system identifies the boot device
and the number "2" displays on the screen. As the system begins booting,
the countdown continues from 1 to O.
Figure 2-3 shows a successful power-on and automatic boot when DUAO
has been selected as the boot device.

MicroVAX 3800 VAXserver 3800 Operation

NOTE: If you do not type a device name within thirty seconds, the system
attempts to boot from the Ethernet device, XQAO.
Changing the Boot Device

Once a boot device is identified, the system autoboots from that device each
time you turn it on, until you do one of the following:
•

Change the setting of the Break EnablelDisable switch to enable (dot
inside the circle). (If you do so, the system will not autoboot but will
enter console mode after completing self-tests.)

•

Change the boot device by using the SET BOOT command.

Using the SET BOOT Command

To direct the system to boot automatically from a specific device or to change
the setting of the default boot device, put the system into console mode
and at the »> prompt, enter "SET BOOT device-name". For example
"SET BOOT XQAO" sets the system default boot device to be the Ethernet
controller.
Once you have selected a boot device, the system autoboots from that device
each time you turn it on. To determine the name of the device from which
to boot the system, refer to Table 2-2.
NOTE: Selecting a default boot device other than the Ethernet device, XQAO,
is not appropriate for diskless and tapeless systems which must boot software
over the network.

tells the system to boot software from a cartridge in the TK70 tape drive.
NOTE: To determine the name of the device from which to boot the system,
refer to Table 2-2.

Software manuals may instruct you to power up with Break 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:
•

Installing software on your system

•

Running software to perform tasks

2-8 MicroVAX 3800 VAXserver 3800 Operation

•

Making and restoring backup copies of system software or data files

•

Accessing devices and utilities in your system

2.6 Turning Off the System
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 o.
CAUTION: If you are using a diskless system that is part of a VAXcluster,
do not turn off, halt, or restart the system without consulting the cluster
manager. Performing any of these activities will interrupt the processes 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 Monitor (MDM)
software.
CAUTION: Halting your system without following the shutdown procedure
described in your system software manuals may result in loss of data.

You can halt the system in two ways:
•

You can press the Halt button twice - in to halt the system, and out
to enter console mode.

•

If the Break EnablelDisable switch on the CPU cover panel is set to
enable (indicated by the dot inside the circle) you can press the IBreakl
key on the console terminal. If the Break EnablelDisable switch is not
set to enable and you wish to halt the system by pressinglBreakl. change
the setting of the Break EnablelDisable switch from disable to enable.

When the console mode prompt »> displays on your screen, the system is
halted.
If you inadvertently halt the system, type "c IReturn f' at the console prompt.
The processes interrupted by the halt continue.

Addendum to Operation
This addendum describes the controls and indicators for the
RF71 Integrated Storage Element (lSE).

The RF71 Integrated Storage Element (ISE) is an intelligent fixed-disk
storage device that handles device operations internally rather than
through a disk controller. It has a formatted storage capacity of 400 Mbytes
and uses the Digital Storage System Interconnect (DSSI) bus and interface.
Your MicroVAX system can contain up to three RF71 ISEs.
When your system has multiple ISEs, DIGITAL recommends that you
separate them according to function. For example, if your system has two
ISEs, you may want to use them as follows.
•

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

•

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

Specifications for RF71 ISEs are listed in the attached Addendum to
Technical Information.
Controls for the RF71 ISEs are located on the Operator Control Panel (OCP)
behind the sliding window on the front of your system. 'lb access the OCP,
tum the key to position 2 or 3 and slide down the window. Figure 1 shows
the OCP.

3.1.2 TK70 Tape Drive
The TK70 tape drive is located behind the sliding window on the front of
the system. To use the drive, move the key to position 2 or 3 and slide down
the window.
The TK70 tape drive holds one removable magnetic tape cartridge. The
drive can read data written on either a COMPACTape II or COMPACTape
cartridge. You can identify the type of cartridge by the label on the
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. (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 II or COMPACTape that has been previously 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 cartridge 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 tell you 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
is loaded. A blinking yellow light indicates that the tape is in motion.

•

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 green light is blinking.

All three lights blinking simultaneously indicates a fault condition.

3-6 MicroVAX 3800 VAXserver 3800 Operation

Figure 3-3 shows the TK70 tape drive with the controls and indicator lights
labeled.
To operate the drive properly, you must carefully monitor the indicator
lights. The instructions for inserting and removing cartridges, which
appear later in this section, tell you what should happen at each step. A
table at the end of the section summarizes light and control combinations.

3.1.2.1 Design of the Drive
The TK70 tape drive operates 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 push
in the handle, 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
is complete, 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.

Operating System Options

3-7

When you press the Unload button, the tape rewinds into the cartridge
and the leaders uncouple.
3.1.2.2 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 and insert the label in the slot on the
front of the cartridge, as shown in Figure 3-4. The label is visible when
the tape is in the drive.
Figure 3-4:

Labeling a Tape Cartridge

To indicate that the tape was recorded on a TK70 tape drive, check the box
labeled 296MB. The 95MB box is used for tapes recorded on a TK50 drive.

3-8 MicroVAX 3800 VAXserver 3800 Operation

NOTE: Do not write on the tape cartridge or attach labels to the top, bottom,
or sides of the cartridge.
3.1.2.3 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.

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. Two icons on the switch indicate the write-protect status,
as shown in Figure 3-5. An orange rectangle is visible when the switch is
in the write-protect position. If you do not see an orange rectangle, slide
the switch toward the label slot.
When you insert a write-protected cartridge into the drive, the orange
indicator light comes on. The system recognizes the tape as being writeprotected under anyone of the following conditions:
•

The write-protect 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 writeprotection 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.

Operating System Options

3-9

Figure 3-5:

Tape Cartridge Write-Protect Switch

MLO-000961

•

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.

3-10 MicroVAX 3800 VAXserver 3800 Operation

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

•

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.

•

Keep tape cartridges away from direct sunlight, heaters, and other
sources of heat. Store tape cartridges in a stable temperature between
100 and 400 Celsius (50 0 and 1040 Fahrenheit).

•

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

•

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

Operating System Options

3-11

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.

2. 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.
NOTE: If the green light blinks rapidly when you push the handle
closed, the drive has detected a cartridge fault. Pull the handle open
and remove the cartridge. Use another cartridge.

Refer to your system software manual for instructions on how to use the
tape cartridge, for example, to load software or perform backup.
NOTE: If a cartridge is new, the drive performs a calibration sequence that
takes approximately 30 seconds when the drive receives the first command
from the operating system. The yellow light blinks rapidly and irregularly
during calibration.

3.1.2.6 Removing a Tape Cartridge

You must unload a tape before you can remove the cartridge from the tape
drive. Use the following procedure (see Figure 3-7):
1. Press the Unload button. You can also issue a software command to
unload the cartridge. Refer to your system software manuals for the
appropriate command.
The yellow light blinks slowly, as the tape rewinds and unloads into the
cartridge. This may take up to 90 seconds.
2. When the yellow light goes off and the green light comes on (you also
hear a beep), pull the handle open.
CAUTION: Move the handle only when the yellow indicator light is off
and the green indicator light is on. Moving the handle while the yellow
light is blinking could damage the drive.

3. Remove the tape cartridge and store it in its container.
4. Push the handle closed.
The green light remains on, indicating that there is power to the drive and
that you can safely move the handle.
CAUTION: Remove the tape cartridge from the tape drive when the cartridge
is not in use or before you turn off the system. Failure to remove the cartridge
may damage the tape cartridge.

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. Refer
to your terminal or printer manual for complete set-up instructions.
Generally, the default settings for your terminal are acceptable.
While most default settings are acceptable, you should perform the setup procedure for your terminal to ensure appropriate set-up values.
The two examples below provide set-up instructions for VT300-series
and VT200-series terminals:

3. Check the settings on the terminal attached to the modem. Depending
on the type of modem and the type of lines used, the baud rate may
be 300, 1200, or 2400. Other settings should be the same as those
described in the previous section.
Before using a phone line with modem support, you must set certain
parameters such as line speed. See your system software manuals for
details.

3.2.2 Synchronous Controllers
The following synchronous controllers are available for your MicroVAX
system:
•

DPVll-Single-line programmable controller

•

DSVll-Dual-line controller

•

KMV1A-Programmable communications interface, Q-bus controller

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 system.

•

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.

3.2.3 Network Controllers
Before using a network controller you must do the following:
1. Make sure the Ethernet cable (either standard transceiver cable or
ThinWire cable) is connected to the DESQA The light next to the
connector should be lit, indicating an active connection. If not lit, move
the Ethernet jumper to the proper position.

2. Make sure the Ethernet cable is properly connected to the network. A
transceiver cable can be connected in one of the following ways:
•

To an H4000 transceiver located on a traditional Ethernet

•

To a Local Network Interconnect (DELNI), which can be connected
to a larger Ethernet or can· serve to connect up to eight systems in
a local area network

3-20 MicroVAX 3800 VAXserver 3800 Operation

A ThinWire cable can be connected as follows:
•

To a ThinWire Ethernet Multiport Repeater (DEMPR) or ThinWire
Singleport Repeater (DESPR), which can be connected to a larger
Ethernet or can serve to connect many systems in a local area
network

•

To an available connection on a T-connector of other ThinWire nodes

3. Have the DECnet application installed on your system.
4. Register your node with the network manager so that your node is
recognized by other systems in the network.
Some software products, for example, Ethernet-based VAXcluster systems,
use the Ethernet hardware address of other systems to operate properly.
To find the hardware address of your Ethernet device, remove the front
panel of your system. The hardware address of your Ethernet device is
printed on a label on the DESQA Ethernet adapter module.
You can also use the command SHOW ETHER from console 1/0 mode.
The hardware address of your Ethernet device displays on the terminal
as shown in the following example:
»>SHOW ETHER
08-00-2B-03-50-5C

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

Appendix B

Reprogramming the KFQSA
Storage Adapter
This appendix describes how to reprogram the KFQSA storage adapter in
the event you are setting up a dual-host system or adding an expander with
additional ISEs to a previously installed MicroVAX 3800. If you are setting
up a dual-host system, follow the instructions in Section B.1, followed by
instructions for setting allocation classes in Section B.2. If you are adding
an expander with additional ISEs, follow the instructions in Section B.3.

B.1 Reprogramming the KFQSA for Dual-Host
Systems
The KFQSA module is a storage adapter that allows Q-bus host systems
which support the KFQSA to communicate with storage peripherals based
on the Digital Storage Architecture (DSA), using the Digital Storage System
Interconnect (DSSI). The DSSI bus supports six RF -series Integrated
Storage Elements (lSEs) and two KFQSA storage adapters, for a total of
eight devices.
The KFQSA makes a connection between the host and a requested ISE.
Each ISE has its own controller that contains the intelligence and logic
necessary to control data transfers over the DSSI bus.
The EEROM on the KFQSA contains an address configuration table. To set
up a dual-host system, you need to program the EEROM in both KFQSAs
(one in each host) to recognize all the ISEs in the dual-host system. You
also need to assign the KFQSA in the second host to node number six.
Figure B-1 is a diagram of the DSSI bus and an example of the nodes and
addresses in a dual-host configuration. Throughout this procedure, the host
with the lower number ISEs (0, 1,2) will be referred to as the first system,
the host with the higher number ISEs, as the second system.
NOTE: Either system need not have the maximum of three [SEs. Each
system can have between one and three [SEs.

Adding the second system's ISEs to the first system may bump the
address of another Q-bus device. Make sure that all device addresses,
other than those of the ISEs, have not changed. If the address
of a device differs between the two displays, your DIGITAL service
representative must reconfigure your system.
5. If no addresses are changed by the addition of the ISEs, repeat steps 1
through 4 for the second system.

NOTE: When repeating step 3.b. be sure to list all devices in the second
system, and all the ISEs in both systems (A and B).
6. Program the KFQSA in the first system.
Program the configuration table in the EEROM of the first KFQSA to
include all ISEs in the system, as follows. Refer to Example B-5.
a. At the console prompt for the first system, type SET HOST /UQSSP /MAINT
followed by a VAX address of one of the currently recognized ISEs
(from the list of addresses you obtained from using the SHOW
QBUS command-in most cases this address will be 20001468.)
This allows you to access the KFQSA in the system.
b. Type HELP to display a list of supported commands.
c.

Program the KFQSA to include each DSSI device in the dual-host
system:

12. Verify the procedure for both systems. For each system:
a. At the console prompt, type SHOW QBUS to verify that all addresses
are present and correct.
b. Type SHOW DEVICE to verify that all ISEs are displayed correctly.
NOTE: Be certain the ISE device names are the same for both
systems. If the device names (DUcv: where c represents the controller
number, and v represents the unit number) are not identical for both
systems, the ISE addresses were not assigned in the proper order (as
listed in the Configure Display).

B.2 Changing the ISE Allocation Class
This section describes how to change the ISE allocation class. For dual-host
configurations you must assign the same nonzero allocation class to both
host systems and their ISEs. The ISEs ship with the allocation class set to
zero.
Change the allocation class parameter using the console-based DUP driver
utility, as follows. Refer to Example B-7.
1. Determine the correct allocation class for the RF -series ISEs according

to the rules on clustering.
NOTE: In a dual-host configuration, you must assign the same
allocation class to both host systems and to the RF-series ISEs. This
allocation class must be different from that of other systems or of
hierarchical storage controllers (HSCs) in a cluster.

2. Enter console I/O mode as follows.
a. Set the Break EnablelDisable switch on the CPU cover panel of one
of the host systems to the enable position (up, dot inside the circle).
b. Set the on/off power switch on both systems to on (1).
Wait for the console prompt >>> to display.
3. At the console prompt, type SET HOST /DUP /UQSSP /DISK 0 PARAMS (0
through 5 for the ISE to which you want to connect) to start the DUP
server.
NOTE: This command is only valid after the KFQSA storage adapters
have been properly configured.

8-10 MicroVAX 3800 VAXserver 3800 Operation

4. At the PARAMS> prompt, type SHOW ALLCLASS to check the current
allocation class.
5. Type SET ALLCLASS 2 to set the new allocation class to 2 (or type the
number you desire).
6. Type SHOW ALLCLASS to check the new allocation class.
7. Type WRITE, then type y to save the new values into the EEROM, or N
to cancel the reprogramming.
8. Repeat steps 3 through 7 for each ISE in the dual-host system.

Storage Elements (ISEs) and two KFQSA storage adapters for a total of
eight devices.
The KFQSA makes a connection between the host and a requested ISE.
Each ISE has its own controller that contains the intelligence and logic
necessary to control data transfers over the DSSI bus.
The EEROM on the KFQSA contains an address configuration table. When
you are adding RF-series ISEs to your system, you need to program the
EEROM in the host system's KFQSA to recognize the new ISEs.
NOTE: Expanders shipped with your new Micro VAX or VAXserver 3800
system are factory-configured. The KFQSA. storage adapter only needs to
be reprogrammed if you are adding an R215F expander to a previously
installed Micro VAX or VAXserver 3800.

B213F expanders added to a previously installed Micro VAX or VAXserver
3800 system must be installed by a DIGITAL service representative.
Figure B-2 shows a diagram of the DSSI bus and an example of the nodes
and addresses in an expanded system.
NOTE: Either unit need not have the maximum of three ISEs. Each unit
can have between one and three ISEs.

4. Compare the Configure utility printout to that of the SHOW QBUS
display.
Adding the expander system's ISEs to the host system may bump the
address of another Q-bus device. Make sure that all device addresses,
other than those of the ISEs, have not changed. If the address
of a device differs between the two displays, your DIGITAL service
representative must reconfigure your system. If no addresses are
bumped by the addition of the ISEs, proceed to the next step to program
the KFQSA.
5. Program the KFQSA storage adapter.
Program the configuration table in the EEROM of the KFQSA to include
all ISEs in the system, as follows. Refer to Example B-12.
a. At the console prompt for the first system, type SET HOST /UQSSP /MAINT
followed by a VAX address of one of the currently recognized ISEs
(from the list of addresses you obtained from using the SHOW
QBUS command-in most cases this address will be 20001468.)
This allows you to access the KFQSA in the system.
b. Type HELP to display a list of supported commands.
c.

Program the KFQSA to include each DSSI device in the expanded
system:
For each DSSI device, type SET, followed by the node number, the
CSR address (from the list of addresses you obtained from the
Configure utility), and the model number (disk ISEs are model 21).

d. Type SHOW to display the configuration table you just programmed.
e.

Check the display against the output of the Configure command to
make sure the addresses are correct.
