Power Connections
The AP can be powered in one of the following ways:
•
Power over Ethernet (PoE)
Power is provided through the RJ45 Ethernet port (LAN port) on the top of the AP. This
is the preferred method of powering the AP on ceiling and high wall installations.
•
Power by external power supply
Where a PoE-capable Ethernet connection is unavailable or impractical, an external 12V
DC power supply may be ordered separately to power the AP from a standard AC wall
outlet.
Connecting an External DC Power Supply to the WS-AP3825
There are no wall mounts for the 12V DC power supplies. To connect a power supply to the
AP for everyday operation, mount the AP and plug the power supply in to the DC-IN port
(callout 3 in
). If you have taken the AP off its mount for configuration
and maintenance, you will still need to get power to it during the maintenance from a DC
power supply or PoE LAN connector.
Configuring AP Channel Settings
The WS-AP3825e must be installed by a professional installer. Before starting the
installation, the installer needs to determine/configure the following:
•
•
•
•
Configure Radio Transmit (Tx) Power
Determine the Antenna Model
The professional installer needs to determine antenna models and the number of antenna
ports for that model. The number of ports can be determined from visual inspection of the
antenna or from the antenna model name as follows:
•
If the antenna model name contains a T or X (for example PRO-AO-xTxxxxx or AO-
xXxxxxx), it is a triple port antenna.
•
If the antenna model name contains a D (for example PRO-AO-xDxxxxx), it is a dual port
antenna.
•
If the antenna model name contains an S (for example PRO-AO-xSxxxxx), it is a single
port antenna.
