2. Seat the AP-85 into the four keyholes on the mounting plate and tighten down the four mounting

bolts (M8 bolts) to secure the AP-85 in place (see Figure 12). The mounting plate should rest

between the captive flat washer on each of the mounting bolts and the rear of the AP-85.

Pole Mounting the AP-85 (1.5” to 3.5” Diameter)

To mount an AP-85 to a pole with a diameter of 1.5” to 3.5”:

1. Slide the long T-bolt through the opening in the mounting bracket (see Figure 13).

2. Attach the included retaining clip to the T-bolt (see Figure 13).

3. Screw the included nut onto the end of the T-bolt (see Figure 13).

4. Secure the mounting plate to the mounting bracket using the four included phillips head screws (see

Figure 13).

NOTE

The positioning of the keyholes on the mounting plate supports horizontal or vertical mounting of the

AP-85, which is achieved by rotating the device by 90 degrees and securing it to the mounting plate.

5. Wrap the pole mounting bracket around a 1.5” to 3.5” diameter pole and secure the bracket in place (see Figure 14). a. Wrap the pole mounting bracket around the pole. b. Slip the end of the T-bolt with nut through the opening in the pole mounting bracket. c. Maneuver the T-bolt to the top slot in the pole mounting bracket and tighten down the nut. Ensure that the nut is tightly secured and that the bracket cannot move. It must be secure to support the weight of the AP-85.

Positioning the AP-85 To adjust the angle of an AP-85 on a vertical pole: 1. Loosen the four M8 bolts on the side of the mounting plate and rotate the AP to the desired angle and tighten down the M8 bolts (see Figure 18). Figure 18 Positioning the AP-85 on a Vertical Pole M8 Positioning Bolts (4x, 2x per side) To adjust the angle of an AP-85 on a horizontal pole: 1. Rotate the entire mounting bracket to the desired angle and tighten the bracket into place (see Figure 19).

Connecting Required Cables RJ-45 CAT 5 Cable To weatherproof and connect an RJ-45 terminated CAT 5E or better cable to an AP-85 (see Figure 20), perform the following using the contents in the included kit that ships with your unit: The cable is not included and must be purchased separately. Purchase a suitable UV resistant, outdoor rated, CAT 5E or better RJ-45 cable for use with the AP-85. NOTE 1. Slide the cap over the terminated cable. 2. Slide the rubber grommet over the terminated cable. 3.

DC and AC Power Cables To connect the power cables (wiring harnesses): 1. Screw the two-wire, 8-foot long DC power cable (wiring harness) to the DC interface on the AP85TX, AP-85FX, or AP-85LX model. 2. Screw the three-wire, 8-foot long AC power cable (wiring harness) to the AC interface on the AP85FX or AP-85LX models only. Disconnect the AC mains before handling the AC power cable and connecting it to the AP-85.
PAGE 7
Fiber Optic Cable To utilize the fiber optic termination kit that ships with the AP-85FX/LX models: 1. Follow the instructions in the included Tyco document: Instruction Sheet 408-10079. Fiber optic cables are not included and must be purchased separately. Purchase a suitable UV resistant, outdoor rated, multi-mode fiber optic cable for use with the AP-85FX and a single-mode fiber optic cable for use with the AP-85LX.

Appendix A Understanding Antennas Aruba Antennas Before you can select the antenna type needed for the deployment, read the basic wireless antenna information provided in this section. This information will help you understand wireless antenna basics and Aruba antenna specifications. Understanding Wireless Antennas Omni-Directional vs. Directional Coverage For optimal performance of your wireless network, it is essential to understand the purpose behind proper antenna selection.

Antenna Beamwidth, Pattern, and Gain Considerations Antenna gain is a relative measure of how the antenna compares to an ideal isotropic radiator. An ideal, isotropic radiator would radiate power in all directions equally over a sphere. The relationship between gain, power, and propagation distance is detailed already in textbooks and Wiki's, so these expressions are not repeated here.

Now, still using the same ball with the same available surface area, how would you be able to stretch the ball farther out? One way is to press down on the top of the ball and squash it down vertically. This would keep the same basic shape in the horizontal plane (round), but it would force the ball to stretch, creating a pancake shape, in the vertical direction (see Figure 25).
PAGE 11
Understanding Antenna Pattern Plots and Specifications Traditional 2-D pattern plots and beamwidth specifications are like mental puzzles waiting to be solved because they only provide a snapshot of the information in two planes. These two planes are often referred to as the azimuth (H-plane or horizontal) and elevation (vertical or E-plane) planes. The azimuth view would be considered the view from directly above, viewing the antenna pattern on the horizontal plane.
