Step 5. Re-install the module handle (LACM heat sink bracket) to the LACM.
a. Place the module handle (LACM heat sink bracket) evenly on the LACM and align screw
holes.
b.
Tighten the five screws. Ensure that the screws are secured in place.
Step 6. Disengage the LACM from processors.
a. Fully loosen the eight Torx T20 nuts in the removal sequence shown on the heat-sink label
on the cold plate assembly and radiator.
b.
Grasp the middle of the module handle (LACM heat sink bracket) and one T20 screw
fastening the radiator to carefully lift the LACM from the processor sockets. If the LACM
cannot be fully lifted out of the socket, further loosen the Torx T20 nuts and try lifting the LACM
again.
Step 7. Place the LACM on the shipping tray.
Step 8. If there is any old thermal grease on the cold plates, gently clean the top of the cold plates with an
alcohol cleaning pad.
