C.4 Installing the Central Processing Unit (CPU)
The Point of Care Terminal's central processing unit (CPU) can be
upgraded to improve system performance. The Point of Care Terminal
provides one 479-pin socket (Socket 479). The CPU must come with an
attached heat sink and CPU fan to prevent overheating.
1. Detach and remove the plastic rear cover.
2. Unscrew the screws that secure the metal fan cover.
3. Detach the CPU fan power cable from the fan connector and
remove the four screws of the heat sink.
4. This will expose the entire CPU assembly underneath.
5. Locate the mPGA479M socket, Mark the Locked and Unlocked
positions on the socket with the universal symbol of the locked and
unlocked pictures shown below.
6. Insert the CPU with the correct orientation. The notched corner of
the CPU (with the white dot) should point towards the triangle
symbol on the socket.
Warning The CPU may be damaged if operated without a heat
sink and a fan.
Caution Always disconnect the power cord from your panel
PC when you are working on it. Do not make connec-
tions while the power is on as sensitive electronic
components can be damaged by the sudden rush of
power. Only experienced electronics personnel
should open the panel PC.
