CHAPTER 1: INTRODUCTION
1.1 B
EFORE YOU START
Thank you for choosing our product. Before you start installing the
motherboard, please make sure you follow the instructions below:
Prepare a dry and stable working environment with
sufficient lighting.
Always disconnect the computer from power outlet
before operation.
Before you take the motherboard out from anti-static
bag, ground yourself properly by touching any safely
grounded appliance, or use grounded wrist strap to
remove the static charge.
Avoid touching the components on motherboard or the
rear side of the board unless necessary. Hold the board
on the edge, do not try to bend or flex the board.
Do not leave any unfastened small parts inside the
case after installation. Loose parts will cause short
circuits which may damage the equipment.
Keep the computer from dangerous area, such as heat
source, humid air and water.

CHAPTER 2: HARDWARE INSTALLATION
2.1 I
NSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Remove the socket protection cap.
Step 2: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
Step 3: Look for the white triangle on socket, and the gold triangle on
CPU should point towards this white triangle. The CPU will fit only
in the correct orientation.

Step 3: Hold the CPU down firmly, and then close the lever toward direct
B to complete the installation.
Step 4: Put the CPU Fan on the CPU and buckle it. Connect the CPU
FAN power cable to the JCFAN1. This completes the installation.
