Step 2: Look for the white triangle on socket, and the gold triangle on
CPU should point forwards this white triangle. The CPU will fit
only in the correct orientation.
Step 3: Hold the CPU down firmly, and then close the lever 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.
