1. Identify the prerequisite and subsequent installation tasks that you must perform in conjunction with this task.

   See Installation Task Overview.

2. Determine where you are installing the switch.
3. Mark this location on each rack post with masking tape.
   

   Counting the number of rack units from the bottom of the rack to the mounting location assists you when marking the other rack posts.

4. Install eight cage nuts into the rack, two cage nuts for each rack post.

   Note -  Each RU mounting location on the rack post has three square holes. For installing the switch, there is no need for a cage nut in the center hole.
