Chapter 3:
A5205 Sensor Zero Configuration
The A5205 Sensor comes with a zero configuration feature that 
enables users to take an unconfigured Sensor and place it on their 
network and have it automatically find and connect to the AirMagnet 
Enterprise Server without having to configure the Sensor first. This 
concept alleviates the cumbersome steps of configuring and 
managing Sensors during deployment. It also reduces the overhead 
during regular maintenance cycles. 
To take advantage of the Sensor zero configuration feature, the user 
must enable the zero configuration feature on the AirMagnet 
Enterprise Server. This feature also carries over to the Sensor 
properties screen on the AirMagnet Enterprise Console. The user can 
change the Sensor’s shared secret key from the Console and have it 
automatically forwarded to the Sensor. 
For more information on Sensor zero configuration, see AirMagnet 
Enterprise User Guide.
Installing the A5205 Sensor
For better performance, the A5205 Sensor should be installed where 
maximum field of view (FOV) can be achieved. This means that it 
should be deployed in places where it can cover as large an area as 
possible with little or no obstruction. The instructions below show 
how to install the sensor using the mounting bracket. 
Installing the A5205 Sensor on a Counter Top
The A5205 Sensor comes with four rubber pads on its back. The pads 
provide traction that help prevent the Sensor from skidding when it 
is placed on a flat (horizontal) surface, such as a counter top. 
A5205 Sensor User Guide.book  Page 13  Thursday, January 15, 2009  1:46 PM

14 Chapter 3: Installing A5205 Sensor
AirMagnet A5205 Sensor User Guide
To install the A5205 Sensor on counter top:
1) Place the A5205 Sensor on a desired counter top, making sure 
that the four rubber pads stay on the bottom of the Sensor for 
traction.
2) Connect the Sensor to the LAN using an RJ-45 cable. 
3) Connect the Sensor to the power source, unless PoE is used.
Mounting the A5205 Sensor on a Wall

the need to run the standard electrical wiring to each and every 
individual sensor. AirMagnet offers two PoE options, and customers 
can typically make their own choice based on the quality of the 
switch to which their AirMagnet sensors will be connected.
Powering Up via an 802.3af-Compliant PoE Injector
To power up A5205 Sensor via an 802.3af-compliant PoE Injector:
1) Connect the PoE injector (via the Data Only port) to a network 
switch or hub, using a 10/100 Ethernet cable. 
2) Connect the PoE injector (via the Power and Data port) to A5205 
Sensor using another 10/100 Ethernet cable.
3) Plug the power cord into an electrical outlet. See Figure 3-2.
