CHAPTER 2: HARDWARE INSTALLATION
2.1INSTALLING CENTRAL PROCESSING UNIT (CPU)
Special Notice:
Remove Pin Cap before installation, and make good preservation for future use. When the CPU is removed, cover the Pin Cap on the empty socket to ensure pin legs won’t be damaged.
Pin-Cap
Step 1: Pull the socket locking lever out from the socket and then raise the lever up to a 90-degree angle.

Motherboard Manual 
Step 2: Look for the triangular cut edge on socket, and the golden dot on CPU should point forwards this triangular cut edge. The CPU will fit only in the correct orientation.
Step 2-1:
Step 2-2:
Step 3: Hold the CPU down firmly, and then lower the lever to locked position to complete the installation.
Step 4: Put the CPU Fan and heatsink assembly on the CPU and buckle it on the retention frame. Connect the CPU FAN power cable into the JCFAN1. This completes the installation.
