Pre-installed wall box

Cat5E UTP cable with network access installed in the wall box

One of the following power sources:

IEEE 802.3af/at-compliant Power over Ethernet (PoE) source

Aruba AP AC-DC adapter kit (sold separately)

One of the following network services:
Aruba Discovery Protocol (ADP)


This device in compliance with governmental requirements, and is designed the so that only authorized network
administrators can change the settings. For more information about access point configuration, refer to the
ArubaOS Quick Start Guide and ArubaOS User Guide.

Identifying Specific Installation Locations

The 303H Series access point must be secured to an Aruba-approved wall or to a desk mount kit. This access
point should be oriented vertically, with Ethernet ports facing downward to facilitate maximum antenna gain.
Use the access point 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 be accounted for during the planning phase and
adjusted for in RF plan.
!
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.

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
!
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.
