Orient the securing clips so that the rubber-coated tabs are toward the back of the chassis.
NOTE: If the securing clips are installed so that the rubber-coated tabs are toward the front of the

While holding down the rubber-coated tab with one hand, push the latch on the securing clip
toward the heat-sink post until it locks the clip onto the post.
