memory cage to the bottom panel of the enclosure. 
 
Important: As you start to unscrew each short screw, look directly below the cage for the

If either of the two short mounting screws for the memory cage strip while you are 
attempting to remove it, the screw will stay attached to its hex standoff located below the 
cage and you will be unable to remove the screw. In this case, do the following. 
 
Note: To avoid scratching the enclosure in the following step, place a piece of sticky note 
paper or removable masking tape over the enclosure edge where you insert the wrench. 
 
•  Insert the Apple Mac Pro wrench (part number 922-8025) around the hex standoff located 
directly below the stripped screw, as illustrated. Turn the wrench to separate the hex standoff 
from the enclosure. If both screws are stripped, alternate turning the wrench between the 
two standoffs so that the memory cage rises evenly. 
 
•  Using a flat-blade screwdriver, lift the cage over both standoffs and slide the cage as 
described in step 3. 
 
See also the replacement note for cages with stripped screws in “Memory Cage with 
Rear Fan.” In addition, order screw 922-7703 to replace any stripped, short screws used in 
securing the memory cage.
