向上垂直提起Mac pro外壳。
提起外壳时,可以按着顶部的散热风扇。
The fan assembly is attached to the rest of the computer by two cables on the IO board side.
Tilt the assembly up away from the IO board.
Do not try to remove the fan assembly yet, as it is still attached by two cables.
While supporting the fan assembly with one hand, loosen the two T8 captive screws in the fan cable bracket.
These screws are captive in the Mac Pro. Do not try to remove these screws from your Mac Pro.
Flip the Mac Pro upside down, 180 degrees.
Remove five 5.1 mm T10 Torx screws from the outer perimeter of the lower case.
Gently separate the other side as well.
Flip the connector up and out of the way of the graphics card.
Repeat this procedure on the other graphics card.
Gently walk the interconnect board straight up off the logic board's slot connection.
It is recommended to lift one side and then the other.
Do not try to remove the interconnect board from the Mac Pro yet, as it is still connected to the IO board.
Flip the interconnect board up and over, exposing the IO board data cable.
Use the same sort of twisting and spreading motion with the flat end of a spudger to separate one side of the IO board data cable.
Remove the power supply cage from the top of the power supply.
By removing this cage, you are exposing internal components of the power supply. Be very careful not to touch any of the power supply components or circuitry.
Be careful not to drop any screws or tools into the power supply, as this may damage the power supply.
Gently shift the power supply to free the AC power inlet cable out of its plastic clip.
Be careful not to try to separate the power supply from the IO board assembly just yet, as it is still connected by the AC power inlet cable.
Lift the IO board up from the IO shield from the end with the AC plug.
Do not attempt to completely separate the IO board from the IO shield, as there are still two cables connecting the two components.
Set the assembly down on a flat surface to access the connectors on the IO board.
Use the tip of a spudger to flip the retaining flap on the IO shield ribbon cable ZIF connector.
Disconnect the IO shield ribbon cable.
