Before You Begin

Refer to the sections below before beginning the installation process.

Pre-Installation Network Requirements

After WLAN planning is complete and the appropriate products and their placement have been

determined, the Aruba controller(s) must be installed and initial setup performed before the Aruba

APs are deployed.

For initial setup of the controller, refer to the ArubaOS Quick Start Guide for the software version

installed on your controller.

Pre-Installation Checklist

Before installing your AP, be sure that you have the items listed below:

Gigabit Ethernet cable of required length

IEEE 802.3at compliant PoE source or AC power source

Aruba Mobility Controller configured and installed on the network

Layer 2/3 network connectivity to your AP

One of the following network services:

Aruba Discovery Protocol (ADP)

DNS server with an “A” record

DHCP Server with vendor specific options

FCC Statement: Improper termination of access points installed in the United States configured to non-US

model controllers will be in violation of the FCC grant of equipment authorization. Any such willful or intentional

violation may result in a requirement by the FCC for immediate termination of operation and may be subject to

forfeiture (47 CFR 1.80).

This section is specific to the AP-277.

Verifying Pre-Installation Connectivity

Before you install APs in a network environment, make sure that the APs will be able to locate and

connect to the controller when they are powered on.

Specifically, you must verify the following conditions:

When connected to the network, each AP is assigned a valid IP address.

APs can locate the controller.

Refer to the ArubaOS Quick Start Guide for instructions on locating and connecting to the controller.

Outdoor 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 routers and antennas and assists in the determination of their placement for

optimal RF coverage. This process is considered WLAN or RF planning and Aruba’s system engineers

can assist in the outdoor planning process.

For WLAN systems being installed outdoors in the USA, the following requirement must be met.

1. Systems must be professionally installed by a qualified engineer familiar with WLAN, including

Aruba trained partners and resellers.

Identifying Specific Installation Locations

You can mount the IAP-277 access point on a wall or pole. Use the AP placement map generated by

Aruba’s RF Plan software application to determine the proper installation location(s). Each location

should be as close as possible to the center of the intended coverage area and should be free from

obstructions or obvious sources of interference. These RF absorbers/reflectors/interference sources

will impact RF propagation and should have been accounted for during the planning phase and

adjusted for in RF plan.

This section is specific to the AP-277.

External antennas for this device must be installed by an Aruba Certified Mobility Professional (ACMP) or other

Aruba-certified technician, using manufacturer-approved antennas only.

The Equivalent Isotropically Radiated Power (EIRP) levels for all external antenna devices must not exceed the

regulatory limit set by the host country/domain.

Installers are required to record the antenna gain for this device in the system management software.

Les antennes externes pour cet appareil doivent être installées par un professionnel de la mobilité certifié

Aruba (ACMP) ou un autre technicien certifié Aruba, en utilisant uniquement des antennes approuvées par le

fabricant.

Les niveaux équivalents de puissance à rayonnement isotrope (EIRP) pour tous les périphériques d'antenne

externe ne doivent pas dépasser la limite réglementaire définie par le pays hôte / domaine.

Les installateurs doivent enregistrer le gain d'antenne pour cet appareil dans le logiciel de gestion du système.

Aruba Networks, Inc., in compliance with governmental requirements, has designed the 277 Series access

points so that only authorized network administrators can change the settings. For more information about

access poit configuration, refer to the ArubaOS Quick Start Guide/Instant Quick Start Guide and ArubaOS User

Guide/Instant User Guide.

Aruba 277 Series Access Points | Installation Guide 7

Identifying Known RF Absorbers/Reflectors/Interference Sources

Identifying known RF absorbers, reflectors, and interference sources while in the field during the installation

phase is critical. Make sure that these sources are taken into consideration when you attach an access point to its

fixed location.

RF absorbers include:

Cement/concrete—Old concrete has high levels of water dissipation, which dries out the concrete, allowing

for potential RF propagation. New concrete has high levels of water concentration in the concrete, blocking

RF signals.

Natural Items—Fish tanks, water fountains, ponds, and trees

Brick

RF reflectors include:

Metal Objects—Metal pans between floors, rebar, fire doors, air conditioning/heating ducts, mesh windows,

blinds, chain link fences (depending on aperture size), refrigerators, racks, shelves, and filing cabinets.

Do not place an access point between two air conditioning/heating ducts. Make sure that access points are

placed below ducts to avoid RF disturbances.

RF interference sources include:

Microwave ovens and other 2.4 or 5 GHz objects (such as cordless phones)

Cordless headset such as those used in call centers or lunch rooms

Access Point Installation

The Aruba 277 Series access points can be installed on a wall or attached to a pole using the AP-270-MNT-H1
