Preface
This equipment generates, uses, and can radiate
radio frequency energy and, if not installed and
used in accordance with the instructions manual,
may cause interference to radio communications.
It has been tested and found to comply with the

Subpart J of Part 15 of FCC Rules, which are
designed to provide reasonable protection
against such interference when operated in a
commercial environment.
Operation of this equipment in 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 correct
the interference.

Introduction
This Installation and Operation Guide describes
how to configure and install the MAE486 and
MBE486 system boards. Any information that
pertains to one system board, but not the other,
will be clearly identified.
Precautions
Before you unpack your components, observe the
following precautions:
Handling the
c;ystem
board
Use extreme care when handling the system
board. Your system board contains very sensitive
components that are prone to damage from elec-
trostatic charge. The charge that every human
body carries will discharge when you touch the
metal of the system board and may damage the
components. Avoid touching any of the system
board metal leads. Before touching the system
board or its components, all of the electrostatic
charges must be discharged from your body to
earth ground.
Unpacking and
installing
All unpacking and installation should be done on
an antistatic mat connected to earth ground
through a one MegOhm resistor. You should wear
an antistatic wristband connected through a one
MegOhm
resistor to earth ground at the same
point as the antistatic mat.
Storing the
system board
If you will be storing the system board, use an
antistatic bag and an antistatic mat. This should
protect your system board and its components
until you are ready to use it.

Introduction Unpacking your components
Unpacking your components
After reading the precautions on page I-l,
ma1
sure you received the following components:
One MAE486 or MBE486 system board.
One diskette that contains the configuration
utility for configuring and testing the system
board.
This Installation and Operation Guide.
A BIOS User’s Manual for the appropriate
BIOS on the system board.
A warranty registration card.
If any components are missing or damaged, con-
tact your dealer immediately.
Please complete the warranty registration car
and return it to Mylex Corporation. This
will
protect your system board if it ever needs service.
What else
YOU
need
You will need the following items to configure
and install the MAE486 and MBE486 system
boards:
l
A large, clear, flat surface that provides easy
access to the system board.
l An industry-compatible enclosure with a
power supply sufficient to drive all compo-
nents in your system. (If you are upgrading
a.
existing system, the enclosure and power sup
ply must be industry standard.) Make sure
you check the power output capacity of the
l-2

What else you need Introduction
power supply to make sure it can drive all the
componets
in your system.
l
A small Phillips screwdriver.
l
A flat-blade screwdriver.
lA small pair of scissors or diagonal cutter.
l
A ballpoint pen.
l
An ashtray or other receptacle to hold loose
screws.
l
A grounded
(3-prong)
AC power outlet.
Using this Guide
This Installation and Operation Guide contains
all the information you need to set up and install
your MAE486 and MBE486 system boards.
