Preface
This manual summarizes technical information about MicroVAX 3500 and
VAXserver 3500 systems. The manual 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
MicroVAX 3500 and VAXserver 3500 systems.

Chapter 3 contains information on expanding your system.

NOTE:

VAXserver 3500 systems are designed to offer maximum performance for

applications that do not require timesharing. Some of the devices and components

listed in this manual are designed for multiuser systems and may not be suitable
for a VAXserver system.

Contact your DIGITAL representative if you have any

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

Chapter

Base System Specifications
All MicroVAX 3500 and VAXserver 3500 base system components reside in a
BA213 chassis, with a 12-slot backplane. The base system includes a central
processor unit (CPU) module, and one to four MS650 memory modules. The

CPU module resides in slot 1 of the backplane. Memory modules can reside
in slots 2 through 5.

1.1

Base System Operation

Base system operation includes the KA650 firmware and the controls on the

CPU cover panel.

1.1.1

KA650 Firmware

Two read-only memory (ROM) chips on the KA650 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
KA650 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 console processor.

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

The system is powered up

The Reset button is pressed

The Q22-bus BHALT signal is asserted (or by pressing the

key

when the Break Enable/Disable switch is set to enable)
*

Halt button on the front control panel is pressed (RA70-based systems

only)

Base System Specifications

1—1

A HALT instruction is executed

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 cover panel. (The modes and

their meaning are described later in this chapter.) The console program then
determines the console device type and console language.

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

Performing normal

system tests

is displayed on the terminal.

As the tests progress, a series of numbers

displays on the console terminal. MicroVAX 3500 VAXserver 3500 Operation
describes the power-on sequence and shows examples of successful poweron operations.

MicroVAX Troubleshooting and Diagnostics 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 Break Enable/Disable switch on the CPU cover panel is set

to disable or enable.

If the Break Enable/Disable switch is set to disable, the CPU tries to load
and start (bootstrap) an operating system. It locates a 128-Kbyte 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.

MicroVAX 3500 VAXserver 3500 Technical Information

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.

If break is enabled, the console program enters console I/O mode in response
to any halt condition except the HALT instruction, 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 1/0
mode.

Use the BOOT command, followed by the device name as listed in

Table 1-1. For example, to boot from the TK70 tape drive, issue the following
command: BOOT MUAO.

For a list and description of the commands available in console I/O mode,

refer to the KA650 CPU Module Technical Manual.

1.1.2 CPU Cover Panel Operation
The outside of the CPU cover panel contains the following components, as

shown in Figure 1-1.

Break Enable/Disable switch

Power-Up Mode switch

Modified modular jack for the console terminal serial line unit (SLU)

The inside of the cover panel (shown in Figure 1-2) contains:
e

Battery backup unit (BBU) for the time-of-year clock and language
selection (see Section 1.1.2.4)

1.1.2.1 Switches

The three switches on the CPU panel are the Break Enable/Disable switch,
the Power-Up Mode switch, and the Baud Rate switch. The operation of
these switches is discussed on the following pages.

push the top until it locks into position.

Push in and turn clockwise the quarter-turn screws at the top and bottom
of the cover panel until the screws are tight.

You can now turn on the system and the new baud rate will be in effect.
1.1.2.2 LED Display

The red LED display on the CPU cover panel displays a numerical sequence
(in hexadecimal numbers) as the system runs its self-test diagnostics and

bootstrap routine. The countdown begins with F (15 in decimal) and ends with
3, if the processor enters console I/O mode (breaks enabled); and ends with
0, if the processor has successfully booted (breaks disabled). Simultaneously,
a countdown appears on the console terminal. See MicroVAX 3500 VAXserver
3500 Operation for examples of successful power-on sequences, and MicroVAX
Troubleshooting and Diagnostics for examples of problems you may encounter
during power-on.

1.1.2.3 Connectors

The console cable is connected to the CPU cover panel through a modified
modular jack (MM]). An internal cable connects the MM] to the CPU module.
A second internal cable connects the switches and LED display to the CPU
module.

1.1.2.4 Battery Backup Unit (BBU)
A battery backup unit (BBU), located on the inside of the CPU cover panel,

maintains the correct time-of-year and language selection on the CPU module
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
seven days if the system power is turned off.

1.2 Base System Specifications
The base system includes a KA650-AA /BA processor and one to four MS650
memory modules.

1.2.2 MS650 Memory Option
One MS650 memory option is available for MicroVAX and VAXserver systems.
Up to four MS650 modules can be used in MicroVAX and VAXserver systems.
The MS650 modules interface with the KA650-AA/BA CPU through the

MS650 local memory interconnect, made up of the CD rows of slots 1
through 5 of the backplane and a 50-pin cable.

1.2.2.1

The MS650-AA memory option is an 8-Mbyte, 39-bit wide array (32-bit data
and 7 error correction code (ECC) bits) implemented with 256-Kbyte dynamic

If you want to add other options to your system, your DIGITAL

sales representative can advise you.

Chapter 3 offers some guidelines on

determining what options you can add to your system.

Options must be properly configured so that the system recognizes them.
Each option in a system has a device address, commonly referred to as
a Control and Status Register (CSR) address, and an interrupt vector that

must be set when the option is installed.

Options are usually configured

by adjusting switches or jumpers on the modules.

Your DIGITAL service

representative configures the option properly when installing the option in
your system.

Self-maintenance customers can find information on setting CSR addresses

2.2.1.5 DSRVB DECserver 200
The DECserver 200 is an 8-line terminal server used to connect terminals to

a host computer on an Ethernet Local Area Network (LAN). Software for the

server is downline-loaded from a host to the server.
In two models:

The server is available
the modem control (MC) model has modem control and an

R5-232-C line interface; the data leads (DL) model has no modem control

and a DEC 423 (DECconnect) line interface.
