CHAPTER 2: HARDWARE INSTALLATION
2.1 INSTALLING CENTRAL PROCESSING UNIT (CPU)
Step 1: Pull the lever toward direction A from the socket and then raise the
lever up to a 90-degree angle.
90
Step 2: Look for the triangle cut edge on socket, and the gold dot on CPU
should point forwards this triangle cut edge. The CPU will fit only
in the correct orientation.

Step 3: Hold the CPU down firmly, and then lower the lever to locked
position to complete the installati on.
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.
2.2 FANHEADERS
These fan headers support cooling-fans built in the computer. The fan
cable and connector may be different according to the fan manufacturer.
Connect the fan cable to the connector while matching the black wire to
pin#1.

1. Unlock a DIMM slot by pressing the retaining clips outward. Align a
DIMM on the slot such that the notch on the DIMM matches the
break on the Slot.
2. Insert the DIMM vertically and firmly into the slot until the retaining
chip snap back in place and the DIMM is properly seated.
Note:
To remove the DDR modules, push the ejector tabs at both sides of the slot outward at
the same time, and pull the modules out vertically.
