ESD Precautions
Integrated circuits on computer boards are sensitive to static electricity.
To avoid damaging chips from electrostatic discharge, observe the
following precautions:
!Do not remove boards or integrated circuits from their anti-static
packaging until you are ready to install them.
!Before handling a board or integrated circuit, touch an unpainted
portion of the system unit chassis for a few seconds. This helps to
discharge any static electricity on your body.
!Wear a wrist-grounding strap, available from most electronic
component stores, when handling boards and components.

Introduction 1
C h a p t e r 1
Introduction
The SBC8153 CPU Card Family consists of PCI Pentium Industrial
CPU cards based on the Intel 430TX chipset and is fully designed for
harsh industrial environment. It features ZIF Socket 7 compatible with
various processors from Intel, AMD and Cyrix. This card
accommodates up to 256MB of DRAMs in FPM or EDO configurations
and a secondary level 512KB cache.
The SBC8153 CPU Card Family comes with onboard CPU
temperature sensor to protect your processor from overheating. The
power management feature provides power savings by slowing down
the CPU clock, turning OFF the monitor screen and stopping the HDD
spindle motor.

"CPU Slow Down: When system overheating is detected, CPU
slows down to prevent CPU damage. The CPU speed is restored
when temperature falls to a safe level. System overheat is
usually caused by malfunctioning of the CPU or system fan.
"Auto Fan OFF: To reduce energy consumption and system
noise, the system fan automatically powers OFF during sleep
mode.
"Temperature Monitoring and Alert: A sensor for the CPU
temperature on the SBC8153 monitors the CPU temperature
and alerts the user through the speaker when temperature
exceeds the safe heat level.

NOTE: The thermal specification of the AMD K6-2-400 CPU has a
maximum thermal power of 22.7W. When using the AMD K6-
2-400 on the SBC8153 CPU Card Family, make sure to install
a compatible CPU cooling fan that can sustain such thermal
power capacity. Ensure that the airflow specifications of the
fan are sufficient enough to provide ventilation to the voltage
regulators beside the CPU socket.
