| 9.2.7 | Preparing a drywall surface for a flush-mounted jack

To mount an RJ-45 jack in drywall, follow these steps:

1. Select a position for the jack that will be 30-45 cm above the floor.
2. Drill a small hole in the selected location.
3. Check for any obstructions behind the hole by bending a piece of wire, inserting it into the hole, and rotating it in a circle.
4. If the wire hits something, you know there is an obstruction there and must select a new location farther away from the first hole. Then you must do the last procedure again until you find an unobstructed location.
5. Determine the size of the opening you will need, for the box that will hold the jack, by tracing an outline of the template that was included with the box or bracket.
6. Before you cut into the wall, use a carpenter's level to make sure the opening will be straight.
7. Use a utility knife to cut the opening. Push the knife through the drywall, inside the template outline, until you have an opening that is large enough to accommodate the blade of either a keyhole saw or a drywall saw.
8. Insert the saw into the hole, and cut along the edge of the penciled outline. Continue cutting, carefully, along the line until you can pull out the piece of drywall.
9. Make sure the box or bracket will fit the opening.
10. If you're using a box to flush-mount the jack, do not secure the box until after you bring the cable to the opening.

Safety Procedure Any time you are working in walls, ceilings, or attics, it is extremely important that you remember to turn off the power to all circuits that go to, or pass through, the work area! If you are not sure if there are wires that pass through the section of the building in which you will be working, a good rule to follow is to shut off all power.
