Installation Guidelines

Overview of the Indoor Installation

Placement of the RoamAbout Access Point

The ideal location to install your RoamAbout Access Point must satisfy the following requirements:

The location must be indoors to protect the unit from extreme weather conditions, excessive heat and humidity, and to keep the unit free from vibration and dust.

The location must provide a connection to a grounding type AC wall outlet (100-240 VAC), using the standard power cord supplied with the unit.

The AC wall outlet ground must be connected to the same grounding system as the RoamAbout Lightning Protector and antenna mast (see Grounding System on page 2-15).

The location must provide a connection to the network backbone via an Ethernet LAN cable going to a hub, bridge, or directly into a patch panel.

The location must be as close as possible to the point where the antenna cable will enter the building (see Placement of the Lightning Protector on page 2-8).
