Constructing a Jack Field
The control unit must be placed within 5 feet of an ac outlet, within one cord length (7, 14, 25 feet or up to a 400 feet of spooled DIW cable) of the network interface, and 6 inches above a jack field. See Figure 38.
FIGURE 38 A well-positioned control unit.
At the location where you plan to install your control unit, do as follows:
1Use the measurements in Figure 38 to mark positions on a wall (or other mounting surface) for the control unit and the jack field. Also, check that the distances from the control unit position to the ac outlet and the network interface are within limits and that the control unit’s distance from the floor allows for easy access.
2Attach a label to the outside of the right door of each jack panel box. Each label should identify the jacks in each box by wiring run number.
3Attach the boxes to each other by meshing their tongues and grooves. See Figure 39. Use only as many boxes as you need.
4Use appropriate screws to attach the jack panel boxes to the mounting surface.
