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.

Installation
This chapter describes the hardware installation procedures on
the SBC81872 all-in-one Socket479 CPU card. The following is
a list of typical peripherals required to build a minimum system:
Power supply and passive backplane
IBM™PC/AT keyboard
Display monitor
Floppy or hard disk with MS-DOS or Flash Disk emulator
3.1 System Memory
The SBC81872 industrial CPU card supports two 184-pin DDR
sockets for a maximum total memory up to 2GB.
3.2 CPU Installation
1.Using the method shown in Figure 1, place the new
processor Into the socket. Align the processor’s pin A1 with
the arrow on the micro-FCPGA socket. The pin A1 of the
processor is identified with an embroidered corner and pin
A1of socket is turn the actuator until The processor drops
completely in.
Note: You should not have to press down the processor. If the
processor doesn’t drop completely into the socket, turn the
actuator until the processor drops completely in.

CPU Cooler Installation
1.. For the first time of installation, please do it step by step.
2.. For the second time or later installation, please start from
step3.
Step1. Remove the liner on the insulator.
Step 2. Remove the release liner on the thermal tape. Be sure
that the blue film has been removed with liner. (only left the
magenta thermal interface on the base of the heat sink)
