Step 2 Install the two metal standoffs from the accessory kit into the system board in the metal standoff attachment locations, as shown in Figure 11-9. Use a 1/4-inch nut driver to tighten the standoffs. Locations for AIM standoffs are denoted by a star pattern around the standoff mounting holes.

Caution Make sure that the standoffs are installed straight. Tighten them gently but firmly. The shoulder must be seated tightly against the system board.

Step 3 Insert the plastic standoff (Figure 11-8) from the accessory kit into the hole in the system board. See Figure 11-9. Press the standoff firmly into the system board to be sure that it is locked to the board.

Note The plastic standoff snaps into the system board. Be sure to insert the locking end of the standoff into the system board. The locking end is the shortest end of the standoff. Figure 11-8identifies the locking end of the plastic standoff used with AIMs.

Note For most AIMs, the plastic snap-in standoff is white. For the AIM2-CUE-K9 and the AIM2-APPRE-104-K9, the plastic standoff is blue and has a slightly larger snap-in feature to accomodate the PCB which is thicker.
