Ethernet Ports
The 277 Series is equipped with two 10/100/1000Base-T (RJ-45) Gigabit Ethernet ports (WAN and LAN port) for
wired network connectivity. The WAN port supports 802.3at Power over Ethernet (PoE), accepting 48 VDC
(nominal) as a standard defined Powered Device (PD) from a Power Sourcing Equipment (PSE) such as a PoE
midspan injector. These ports have RJ-45 female connectors with the pin-outs shown in Figure 3.

Reset Button
The reset button can be used to return the AP to factory default settings. To reset the AP:
1. Power off the AP.
2. Press and hold the reset button using a small, narrow object, such as a paperclip.
3. Power on the AP without releasing the reset button. The system LED will flash within 5 seconds.
4. Release the reset button.
The system LED will flash again within 15 seconds indicating that the reset is completed. The AP will now
continue to boot with the factory default settings.
AC Power Interface
The 277 Series is capable of AC power in the range of 100 - 240 VAC. The power cord or power connector kit are
sold separately.
Grounding Point
Always remember to protect the AP by installing grounding lines. The grounding connection must be complete
before connecting power to the AP enclosure.

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.

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
mounting kit.
!
Use of this equipment adjacent to or stacked with other equipment should be avoided because it could result in
improper operation. If such use is necessary, this equipment and the other equipment should be observed to
verify that they are operating normally.
!
Portable RF communications equipment (including peripherals such as antenna cables and external antennas)
should be used no closer than 30 cm (12 inches) to any part of the access point. Otherwise, degradation of the
performance of this equipment could result.
!
RF Radiation Exposure Statement: This equipment complies with RF radiation exposure limits. This equipment
should be installed and operated with a minimum distance of 13.78 inches (35cm) between the radiator and
your body for 2.4 GHz and 5 GHz operations. This transmitter must not be co-located or operating in conjunction
with any other antenna or transmitter.
Déclaration sur les limites d'exposition aux radiofréquences : cet équipement est conforme aux limites
d'exposition aux rayonnements radioélectriques spécifiées. Il doit être installé et utilisé à une distance minimale
de 35 cm par rapport à votre corps pour les fréquences de 2,4 et 5 GHz. Cet émetteur-récepteur ne doit pas être
utilisé ou situé à proximité d'autres antennes ou émetteurs-récepteurs.
The IAP-277 access point does not ship with any mounting kit. The AP-270-MNT-H1 mounting kit is available as
accessories and must be ordered separately.
