Installing air shroud:
Align the air shroud with the guide slots on the system.
Lower the air shroud into the system until it is firmly seated.
NOTE When firmly seated, the memory socket and processor numbers marked on the air shroud aligns with the respective memory socket and processor numbers marked on the system.
Installing the expansion card risers:
If installed, remove the riser blanks and if required loosen the captive screws.
NOTE:Store the riser blanks for future use. Filler brackets must be installed in empty expansion card slots to maintain Federal Communications Commission (FCC) certification of the system. The brackets also keep dust and dirt out of the system and aid in proper cooling and airflow inside the system.
Holding the edges or the touch points, align the holes on the expansion card riser with the guides on the system board.
Lower the expansion card riser into place and press the touch points until the expansion card riser connector is fully seated on the system board connector.
Tighten the captive screws on the risers and system if any.
Installing a processor and heat sink module:
Align the pin 1 indicator of the heat sink to the system board and then place the processor and heat sink module (PHM) on the processor socket.
CAUTION To avoid damaging the fins on the heat sink, do not press down on the heat sink fins.
NOTE Ensure that the PHM is held parallel to the system board to prevent damaging the components.
Push the blue retention clips inward to allow the heat sink to drop into place.
Using the Torx #T30 screwdriver, tighten the screws on the heat sink in the order below:
Partially tighten the first screw (approximately three turns).
Tighten the second screw completely.
Return to the first screw and tighten it completely.
Installing a memory module:
Locate the appropriate memory module socket.
CAUTION Handle each memory module only by the card edges, ensuring not to touch the middle of the memory module or metallic contacts.
