About the Aruba AP-120 Series Access Points
The Aruba AP-120 series of wireless access points support the imminent IEEE 802.11n (currently draft
2.0) standard for high-performance WLAN. These access points use MIMO (Multiple-in, Multiple-out)
technology and other high-throughput mode techniques to deliver high-performance, pre-802.11n
2.4GHz and 5GHz functionality while simultaneously supporting existing 802.11a/b/g wireless services.
The AP-120 series access points are available in versions with single or dual radios and with integrated
antennas or RP-SMA interfaces that support detachable antennas. The AP-120 series access points work
only in conjunction with an Aruba Mobility Controller.
The Aruba AP-120 series access points provide the following capabilities:
zWireless transceiver
zProtocol-independent networking functionality
zIEEE 802.11a/b/g or 802.11n operation as a wireless access point
zIEEE 802.11a/b/g or 802.11n operation as a wireless air monitor

2Aruba AP-120 Series Indoor Access Point | Installation Guide
Before You Begin
WLAN Planning
Determine how many Aruba APs are needed for your wireless network deployment and where they will
be installed. You can easily accomplish this planning using Aruba’s automated RF Plan site-survey
software (available separately). This process is considered WLAN or RF planning and should have been
completed during the master Aruba Mobility Controller installation and configuration. In typical Aruba
installations, the mobility controllers are configured and installed before the APs.
For WLAN planning assistance, refer to the Indoor Access Points: Site Survey and Planning Pre-
Deployment Guide and the RF Plan Installation and User Guide.
Pre-Installation Network Requirements
After WLAN planning is complete and the appropriate products and their placement have been
determined, the Aruba Mobility Controller(s) must be installed and initial setup performed before the
Aruba Access Points are deployed.
For initial setup of the Mobility Controller, refer to the ArubaOS Quick Start Guide for the software
version installed on your controller.
Pre-Installation Checklist
Before installing your AP-120 series access point, be sure that you have the following:
zFor the AP-120/AP-124: External antennas as specified in the network deployment plan

It is important that you verify the items listed under Pre-Installation Checklist before you attempt to
set up and install an AP-120 series AP.
Aruba AP-120 Series Indoor Access Point | Installation Guide 3
Successful setup of an AP-120 series access point consists of four tasks, which must be performed in
this order:
1. Verify pre-installation connectivity.
2. Identify the specific installation location for each AP.
3. Install each AP.
4. Verify post-installation connectivity.
5. Configure each AP.
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 Mobility Controller when powered on.
Specifically, you must verify the following conditions:
zWhen connected to the network, each AP is assigned a valid IP address
zAPs are able to locate the Mobility Controller (Mobility Controller Discovery)
Refer to the ArubaOS Quick Start Guide for instructions on locating and connecting to the Mobility
Controller.
Identifying Specific Installation Locations
You can mount the AP-120 series access point on a wall or on the ceiling. 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.
NOTE
Aruba Networks, in compliance with governmental requirements, has designed the AP-120 series
access points so that only authorized network administrators can change the settings. For more
information about AP configuration, refer to the ArubaOS Quick Start Guide and Aruba OS User
Guide.
!
CAUTION
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
RF Radiation Exposure Statement: This equipment complies with FCC RF radiation exposure
limits. This equipment should be installed and operated with a minimum distance of 13.78 inches
(35 cm) 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. When
operated in the 5.15 to 5.25 GHz frequency range, this device is restricted to indoor use to reduce

4Aruba AP-120 Series Indoor Access Point | Installation Guide
Unidentified 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 AP to its fixed location.
RF absorbers include:
zCement/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 within
the concrete, blocking RF signals.
zNatural Items: Fish tanks, water fountains, ponds, and trees
zBrick
RF reflectors include:
zMetal 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
zDo not place an AP between two air conditioning/heating ducts. Make sure that APs are placed
below ducts to avoid RF disturbances.
RF interference sources include:
zMicrowave ovens and other 2.4 or 5 GHz objects (such as cordless phones)
zLunch rooms and call centers with cordless headsets
Installing the AP
Using the Integrated Wall-Mounting Slots
The keyhole-shaped slots on the back of the AP can be used to attach the device upright to an indoor
wall or shelf. When you choose the mounting location, allow additional space at the right of the unit for
cables.
1. At the mounting location, install two screw on the wall or shelf, 1 7/8 inches (4.7 cm) apart. If you
are attaching the device to drywall, Aruba recommends using appropriate wall anchors (not
included).
2. Align the mounting slots on the rear of the AP over the screws and slide the unit into place (see
Figure 2).
NOTE
Service to all Aruba Networks products should be performed by trained service personnel only.
