486MBS Series Manual
Configuration
This chapter provides all the necessary information for installing the 486MBS Series into a stan-
dard PC chassis. Topics discussed include: installing the CPU (if necessary), DRAM installation,
jumper settings for CPU, cache and standard I/O.
Handling Precautions
The 486MBS has been designed to be as rugged as possible but it can be damaged if dropped,
jarred sharply or struck. Damage may also occur by using excessive force in performing certain
installation procedures such as forcing the system board into the chassis or placing too much torque
on a mounting screw.
Take special care when installing or removing the system memory SIMMs. Never force a SIMM
into a socket. Screwdrivers slipping off a screw and scraping the board can break a trace or compo-
nent leads, rendering the board unusable. Always handle the 486MBS Series with care.
Special Warranty Note:
Products returned for warranty repair will be inspected for damaged caused by improper installa-
tion and misuse as described in the previous section and the static warning below. Should the
board show signs of abuse, the warranty will become void and the customer will be billed for all
repairs and shipping and handling costs.
STATIC WARNING
The 486MBS Series contains delicate electronic semiconductors that are highly sensitive to
static electricity. These components, if subjected to a static electricity discharge, can be
weakened thereby reducing the serviceable life of the system board. BEFORE THE BOARD IS
REMOVED FROM ITS PROTECTIVE ANTISTATIC PACKAGING TAKE PROPER
PRECAUTIONS! Work on a conductive surface that is connected to ground. Before touching
any electronic device, ground your self by touching an unpainted metal object or, and highly
recommended, use a grounding strap.
