Verifying Pre-Installation Connectivity
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.
Outdoor Planning and Deployment Considerations
Prior to deploying an outdoor wireless network, the environment must be evaluated to plan for a successful
WLAN deployment. Successfully evaluating the environment enables the proper selection of 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.
Identifying Specific Installation Locations
You can mount the 370 Series 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.
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 AP to its fixed
location. Examples of sources that degrade RF performance include:
Cement and brick
Aruba in compliance with governmental requirements, has designed the 370 Series access points so that only
authorized network administrators can change configuration settings. For more information about AP
configuration, refer to the ArubaOS Quick Start Guide and ArubaOS/Instant 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.
The instructions in this section are applicable to the 370 Series access points running ArubaOS only.
The rules for the 5600-5650 MHz band vary by region.
