Aruba 303P Series Campus Access Points
| Installation Guide
Before you install access points in a network environment, make sure that the access points 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 access point is assigned a valid IP address.
Access points are able to locate the controller.
Refer to the
ArubaOS Quick Start Guide
for instructions on locating and connecting to the controller.
Identifying Specific Installation Locations
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.
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
Installing the Access Point
The access point ships with a ceiling mount adapter to attach to a 9/16” or 15/16” ceiling rail. Additional ceiling or
wall mount kits are sold separately as accessories.
1. Pull the necessary cables through a prepared hole in the ceiling tile near where the access point will be
placed.
2. Place the mount adapter against the back of the access point with the mount adapter at an angle of
approximately 30 degrees to the tabs (see
Figure 3
).
Twist the mount adapter clockwise until it snaps into place in the tabs (see
Figure 3
).
Service to all Aruba products should be performed by trained service personnel only.
!
The installer is responsible for securing the access point onto the ceiling tile rail in accordance with the steps
below. Failure to properly install this product may result in physical injury and/or damage to property.
