| 8.9.7 | Company B: MDF location
You have been directed to develop a wiring plan for company B, which occupies the sixteenth, seventeenth, and eighteenth floors of the same building as company A. A study has been conducted and all work areas have been mapped on a plan of each floor. The plans include the selections for the wiring closet on each floor. These are shown in the building profile in the graphic. Because company B only occupies three floors of the building, and because it is so far from the POP, you have made the decision to locate the MDF on the sixteenth floor. The remaining wiring closets, located on the seventeenth and eighteenth floors, will be IDFs.
