Chapter 1 AP-85 Series Hardware Overview About the AP-85 Series The AP-85 Series consists of resilient, environmentally hardened, outdoor rated, dual-band IEEE 802.11a/b/g devices, which can be configured for deployment as a wireless access point, air monitor, mesh point, or mesh portal. This outdoor access point series is part of Aruba’s comprehensive wireless network solution.
Minimum Software Requirements The AP-85 Series requires ArubaOS 3.2.0 or later. ArubaOS software builds prior to version 3.2.0 do not support the AP-85 Series. If your network currently runs on a software build prior to 3.2.0, you must upgrade the software on your master and local controllers to 3.2.0 or later prior to installing an AP-85 in your existing network.
Hardware Model Overview AP-85 Series Front View The front of the AP-85 Series consists of LED status indicators (see Figure 1). For descriptions of the LEDs and their behavior, refer to LED Status Indicators on page 12. Figure 1 AP-85 Series Front View LED Status Indicators AP-85 Series Rear View The rear of the AP-85 Series consists of four mounting holes (see Figure 2). Refer to Chapter 3, “AP-85 Series Installation” on page 21 for mounting and installation instructions.
AP-85 Series Top View The top of the AP-85 Series consists of four, female N-type antenna interfaces (see Figure 3). Figure 3 AP-85 Series Top View Four, Female N-Type Antenna Interfaces. RADIO 0 supports 2.4 Ghz; RADIO 1 supports 5 GHz The AP-85 Series requires the use of detachable, outdoor rated antennas. Select the correct antenna type to support the required frequency band (2.4 or 5 GHz) and the desired coverage pattern.

If the AP-85FX/LX is not connected to a DC power source, the AP must be powered via an AC power source. An outdoor rated, three-wire, 8-foot long AC power cable (wiring harness) is supplied with the unit.

Chapter 2 Outdoor Planning and Deployment Considerations Planning and Deployment Considerations Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a successful Aruba WLAN deployment. Successfully evaluating the environment enables the proper selection of Aruba APs and antennas and assists in the determination of their placement for optimal RF coverage.

z Check the topology of the land between the antennas using topographical maps, aerial photos, or even satellite image data (software packages are available that may include this information for your area). z Avoid a path that may incur temporary blockage due to the movement of cars, trains, or aircraft. Antenna Height A reliable wireless bridge or mesh link is usually best achieved by mounting the antennas at each end high enough for a clear radio line of sight between them.
Figure 9 Antenna Height and Line of Sight Radio Line of Sight Visual Line of Sight 3 miles (4.8 km) 2.4 m A 5.4 m B 1.4 m 9m 20 m 17 m 12 m A wireless bridge or mesh link is deployed to connect building A to building B, which is located three miles (4.8 km) away. Mid-way between the two buildings is a small tree-covered hill. From the above table it can be seen that for a three-mile link, the object clearance required at the mid-point is 5.3 m (17.4 ft).
scan your proposed site using a spectrum analyzer to determine if there are any strong radio signals using the 802.11a/b/g channel frequencies. Always use a channel frequency that is furthest away from another signal. If radio interference is still a problem with your wireless bridge or mesh link, changing the antenna direction may improve the situation.

Chapter 3 AP-85 Series Installation Pre-Installation Network Setup Once WLAN planning is complete and the appropriate products and their placement have been determined, installation and initial setup of the Aruba Mobility Controller(s) is required prior to deployment of Aruba Outdoor Access Points. For initial setup of the Mobility Controller, refer to the ArubaOS Quick Start Guide for the software version installed on your controller.
Access Points are radio transmission devices and as such are subject to governmental regulation. Network administrators responsible for the configuration and operation of Access Points must comply with local broadcast regulations. Specifically, Access Points must use channel assignments appropriate to the location in which the Access Point will be used. ! CAUTION 1.
Mounting the AP-85 Preparing the AP-85 for Installation 1. Install the four included mounting bolts (M8 bolts with captive flat washer) into the four mounting holes on the rear of the AP-85 (see Figure 10). Leave approximately two to three threads showing on the mounting bolts.
