Chapter 2: Preparing for Installation
2. Preparing for Installation
This chapter describes safety precautions and product information you have to
know. Read this chapter before installing the Wireless Ethernet Extender.
Professional Installation Required
Seek assistance from a professional installer who is well trained in RF installation
and knowledgeable in the local regulations.
Safety Precautions
To keep you safe and install the hardware properly, read and follow these safety
precautions.
1. If you are installing the Wireless Ethernet Extender for the first time, for your
safety as well as others’, please assistance from a professional installer who has
received safety training on the hazards involved.
2. Keep safety as well as performance in mind when selecting your installation
site, especially where there are electric power and phone lines.
3. When installing the Wireless Ethernet Extender, note the following things:
• Do not use a metal ladder;
• Do not work on a wet or windy day;
•W
ear shoes with rubber soles and heels, rubber gloves, and a long-sleeved shirt
or jacket.
4. W
hen the system is operational, avoid standing directly in front of it. Strong RF
fields are present when the transmitter is on.
Installation Precautions
To keep the Wireless Ethernet Extender well while you are installing it, read and
follow these installation precautions.
1. U
sers MUST use a proper and well-installed grounding and surge arrestor with
the Wireless Ethernet Extender; otherwise, random lightning could easily cause
fatal damage to the unit.
WARNING: EMD (Lightning) DAMAGE IS NOT COVERED UNDER
WARRANTY.
2. Users MUST use the power cord and PoE injector shipped in the box with the
Wireless Ethernet Extender. Using other options will damage the unit.

Using the Grounding Wire
The extender has a grounding wire. Be sure to connect the extender, cables, and
PoE injector to earth ground properly during normal use to protect against surges
or ESD.
1. R
emove the screw on the grounding point at the bottom of the Wireless
Ethernet Extender.
Figure 3-4. Grounding point on the extender.
2. Put the grounding wire on the grounding point at the bottom of the Wireless

Chapter 3: System Installation
Install the External Antenna
The Wireless Ethernet Extender provides two reverse SMA antenna connectors for
connecting the external antennas.
Figure 3-6. External antenna connectors.
1. C
onnect your external antennas to the SMA-type connectors on top of the
Wireless Ethernet Extender. For longer distance, we recommend using
higher-gain antennas to best suit the application.
Figure 3-7. External antennas connected to the extender.
WARNING: U
sers MUST power off the extender first before connecting the
external antennas to it. Do not power on the device without physically
attaching the antenna; otherwise, your extender might be damaged.

3. Y
ou may turn one antenna 45 degrees to the left and the other 45 degrees to
the right. The tilted antennas couple together much less than if they are both
pointed in the same direction.
NOTE: Align the polarization of the antennas properly. Maximum signal strength
between bridges occurs when both antennas are using identical
polarization.
4. Tighten the connector joint clockwise to fix the antennas.
Figure 3-9. Tighten the connector clockwise.
Page 10
724-746-5500 | blackbox.com
Chapter 3: System Installation
5. To adjust antennas, loosen the connector joint counterclockwise first, then
adjust the antenna to the desired position. DO NOT bend or turn the antennas
without loosening the connector joint; otherwise, you might damage the
antennas.
6. Antenna installation is complete.
Figure 3-10. Installed antennas.
Mount the AP on a Pole
1. T urn the Wireless Ethernet Extender over. Put the pole mounting ring through
the middle hole of it.
NOTE: Unlock the pole mounting ring with a screw driver before putting it
through the device as the following right picture shows.

4. Configuration
The Wireless Ethernet Extender covers “Thin AP mode,” “AC+Thin AP mode,”
and “FAT AP mode.” The default mode is Thin AP. To allow the Wireless Ethernet
Extender to manage the thin APs, you need to switch one of the Wireless
Ethernet Extender to virtual controller mode first. To change the mode, do the
following.
1. T o connect the Wireless Ethernet Extender to your PC, plug one end of an
Ethernet cable into the LAN port of PoE injector the other end into the LAN
port of the PC. Then power on the Wireless Ethernet Extender using the PoE
from PoE injector.
2. Assign a static IP address to your PC that should be in the same network
segment with the Wireless Ethernet Extender. The default IP address of the
extender is 192.168.1.1; you may choose from 192.168.1.2 to 192.168.1.254.
Then click “OK.”
Figure 4-1. TCP/IP properties screen, general tab.
3. O
pen the web browser on your PC, type in the IP address (192.168.1.1) of the
Wireless Ethernet Extender in the address bar, and then press “Enter.”

Configure the AC+Thin AP mode
5. T o operate as AC+Thin AP mode, go to Basic Settings. From the Device Mode
drop-down list, select “Virtual AC” mode. To use the extender as a virtual
controller and access point concurrently, select “Virtual AC + Thin AP” mode.
Then assign an IP address to the Wireless Ethernet Extender and specify subnet
mask, gateway, and DNS address, respectively. Press “Apply” and wait for
about 50 seconds to take effect.
Figure 4-4. Basic settings screen.
NOTE: AC+ Thin AP mode allows the Wireless Ethernet Extender to operate as
access controller and thin AP at the same time.
NOTE: To operate the extender as a standalone Access Point, wireless client, or
bridge, select FAT AP from device mode.
For Virtual Controller + Thin AP mode, if you need to configure the wireless settings for the Wireless Ethernet Extender, especially SSID and encryption method,
go to Wireless Settings —> Wireless Networks and click on “#1 Wireless SSID”
for configuration. Click “Save” to save the settings.

hoose Wireless —> Basic Settings. The default is AP mode already. Here, you
can set the parameters to optimize your application, or you can leave them as
the default. Click “Apply” to save the parameters.
NOTE: In the example here, we only change the “Wireless Network Name (SSID)”
as “Join_me”, and later, we will show you if AP mode works correctly. In
addition, for better coverage of the AP, you may also use an external
antenna; if so, remember to set the antenna setting from “Internal (8 dBi)”
to “External (N-Type)” after your external antenna is successfully installed.
You are able to choose “External (N-Type)” only when you have installed the
external antenna; otherwise, it might cause damage to the Wireless Ethernet
Extender itself.

NOTE: The bridge uses the WDS protocol that is not defined as the standard, so
compatibility issues between equipment from different vendors may arise.
Moreover, Tree or Star shape network topology should be used in all WDS
use-cases (i.e. if AP2 and AP3 are specified as the WDS peers of AP1, AP2
should not be specified as the WDS peer of AP3 and AP3 should not be
specified as the WDS peer of AP2 in any case). Mesh and Ring network
topologies are not supported by WDS, so do not use them.
