CAUTION
This equipment generates, uses,
and
can radiate radio frequency energy
and
if
not installed
and
used in accor-
dance with the instructions manual, maycause interference to radio communications.
It
has
been tested
and
found to comply with the limits for a Class A computing device pursuantto Subpart J
of
Part
15 ofFCC Rules,
which
are
designed to provide reasonable protection against such interference when operated in a commercial
environment. Operation
of
this equipmentin a residential
area
is likely to cause interference in which case the
user
at
his own expense will
be
required to take whatever measures may be required to correctthe interfer-
ence.
This digital apparatus does not exceed the Class A limits for radio noise emissions from digital apparatusset
out in the Radio Interference Regulations
of
the Canadian Department
of
Communications.

This manual contains procedures for installing, cabling, and removing a Sun
3400CPU Board.
Procedures for configuring a Sun 3400 CPU Board are covered in the separate Sun
3400
CPU
Configuration Procedures manual.
Subjects that are not directly related to the boards, such as unpacking and setting
up the system, connecting the monitor and accessing the backplane, are covered
in the installation manual that came with your system.
The contents
of
this manual are:
General Description -describes the features
of
the Sun 3400 CPU board.
BoardInstallation andRemoval-describes how to install and how to remove
the Sun 3400 CPU board.
Cabling -describes how to connect the keyboard cable and an Ethernet cable to
the Sun 3400 CPU board and how to connect a mouse cable to the keyboard. This
chapter also includes information to help you predetermine compatibility before
connecting peripheral devices to the Sun 3400CPU board's serial ports.
Power-Up
and
Self-Test-describes
the functions
of
the Sun 3400 CPU board's
switches and
LEDs
indicators. This chapter also briefly describes procedures for
selecting normal
or
diagnostic mode boot-up.

The table
of
Revisions is a record
of
the revisions to this manual.
The Reader Comment Sheet at the back
of
this manual is for you to tell SUN
what you think
of
the usefulness and accuracy
of
this manual. Your comments
are important to us. Anything you tell us is greatly appreciated. After yournew
3400
CPU
board is installed and running, please take a few minutes to
fill
out this
sheet and return it to us.
We would like to emphasize that this Sun 3400
CPU
Board Installation
Procedures manual outlines rather than exhausts any
of
the topics it contains. The
documents listed below include related information. We urge you to read these
documents should you need further information
on
related topics.
A number
of
Sun systems use the Sun 3400 CPU. These systems are shipped
with a set
of
three documents; the System Overview, the System Enclosure Ins-
tallation Manual, and the CPU Installation Manual. The System Overview
describes the system and the documentation, the System Enclosure Installation
Manual describes how to unpackage and install the system, and the CPU Installa-
tion Manual (that's this one) describes how to cable the CPU and how to remove
)~
and replace it. It also provides other information specific to the CPU.

General Description
Standard features
of
the
Sun
3400
CPU
board include:
o
A 68030 central processor with separate internal 256 byte instruction and
data caches and
an
address translation cache (ATC)
for
CPU
address transla-
tion.
The
data cache is designed as a write-through cache.
Both
the data and
instruction caches are structured as
32
blocks
of
16 bytes each.
The
68030
runs
at
33 MHz.

A central cache configured as a 64 kbyte writebackcache.
An
1/0
cache that supports 16 byte blocks.
A 68882
floating
Point Coprocessor running
on
the same 33MHz clock as
the
CPU.
A
VMEbus
arbitration and diagnostic
mode
for
DVMA
interface testing
on
the
board.
64-bit
multiplexed address/data bus memory with support for both 8MB and
32MB
ECC
memory
boards and the
Sun-3
floating
Point
Accelerator
Board.
The
main memory address space is
30
bits.
P4
bus support that allows a variety
of
video daughter boards to
be
used.
P2
MEZZ
bus support that allows the
Sun
FPA+
to
be
used.
Interface circuitry that supports the
VMEbus,
Ethernet, two serial ports, the
keyboard, and the mouse.
An
optional feature is the Data Ciphering Protocol
(DCP)
Processorchip set. This
chip setprovides additional security for your sensitive files
by
encrypting net-
work data.
