PoE Injector Connections
After grounding the PoE Injector, it can be mounted on a wall or secured otherwise in an
accessible location. Figure 3-3 illustrates the placement of the RJ11 and RJ45 cables.
Figure 3-3 PoE Injector Indicators and Connectors
Connecting the PoE Injector:
1. Connect the PoE Injector to the power module via the PWR IN RJ11 jack
(see Figure 3-3).
2. Connect the PoE Injector to the computer or network via the ETH IN RJ45 jack
(see Figure 3-3).
3. Connect the PoE Injector via the RJ45 jack running from the ETH OUT port on
the back to the Ethernet Port ETH A on the unit (as shown in Figures 3-4a and
3-4b).
Note:
The RJ45 cable connector pin needs to be removed and re-attached
in order to t the ETH port gland on the unit. This is to ensure that the
connections are fully weather-proofed. Please refer to the following
instructions on connecting the RJ45 cable.

RJ45 Cable Connection:
1. Remove the RJ45 connector pin from the cable using pliers or other tool and
pass the cable through the ETH gland outer and inner covers as shown in
gure 3-5.
2. Remove 5mm of the outer shield cover for each colored inner cable and trim
them.
3. Match the color of each cable sequentially to the other end with respect to the
connector pin number and place it in the connector slot.
4. Use the crimping tool to crimp the cables and re-attach the RJ45 connector pin.
5. Screw on the inner gland cover onto the unit and then screw on the outer gland
cover onto the inner gland cover. Ensure that the cable is covered completely by
the outer gland cover with no room for water to enter.

Note:
The second RJ45 port, ETH B, as shown in Figure 3-4a/b/c, is available for
daisy chaining to another device. To connect the second device, follow the
procedure as outlined above. This is not applicable for the airClient Nexus
TOTAL (sB3413 and sB3414) and airClient TOTAL (sB3415) which does not
have a second ethernet port.

and log in to the unit using the Web GUI. It is recommended that the unit be congured and
tested on the bench before mounting in the outdoor location to ensure that it is performing
satisfactorily. Please refer to the relevant product User Guide for conguration information.
You can access the User Guide from the support center website at
http://www.smartbridges.com/support/
In order to return the device to default factory settings, you may use the reset button on
the side of the PoE Injector to reset the unit. You will need to press and hold the reset
button using a small pointed object such as a paperclip for 15-20 seconds. Refer to Fig 3-3.
During boot up, reset or other operations, the LED display will ash according to the table

Chapter 4 - Mounting
This section describes how to physically mount the smartBridges’ TOTAL series of products
on the site. The chapter contains the following sections:
• Important Considerations when Choosing the Mounting Location
1. Link Distance
2. Signal Path Clearance (Fresnel Zone)
• Mounting the TOTAL Unit
1. Tower or Pole Mounting
2. Wall Mounting
• Changing Antenna Polarization
Important Considerations when Choosing the Mounting
Location
Each Radio Frequency (RF) application is a unique installation. A site survey is needed
to determine the optimum use of the TOTAL unit to optimize link distance, coverage, and
network performance. The most important considerations are link length and clearance from
obstacles.
The following operating and environmental conditions should be taken into account when
performing a site survey:
• Data rates - Sensitivity and range are inversely proportional to data bit rates. The
data rate increases with a decrease in link distance and/or decrease in receiver
sensitivity.
• Antenna placement - Proper antenna conguration is critical in maximizing radio
range in maximizing radio range. In general, greater heights allow for longer
distances and the avoidance of obstructions. However, do not install the TOTAL
unit at the extreme top of a tower, radio mast or high building to minimize risk of
being directly struck by lightning. It is advisable to install it at least 2 feet below
such heights. Extra height may also increase potential interference from other
unlicensed radio systems.
Note:
Do not install the unit in the proximity of a TV or Radio receiving mast.

16

• Physical environment - Clear, open areas provide better radio range than
enclosed, crowded areas. Physical obstructions such as buildings, trees, or hills
can hinder performance of wireless devices. Avoid locating the TOTAL unit
where there is an obstruction between the sending and receiving antennas.
1. Link Distance
If there is no obstacle in the signal path, the maximum link distance depends primarily on the
type of antenna and the free space path loss. Ensure that your proposed mounting site is
within range of the remote antenna. To help estimate the range, the TOTAL unit has a built-in
Link Budget Calculator under Tools in the Web GUI which is accessible upon logging into
the unit. Please refer to the product User Guide for more information on this tool.
2. Signal Path Clearance (Fresnel Zone)
A radio beam travels from one antenna to another in a straight line. Therefore, the path
between the antennas must be free of major obstacles. The effects of obstacles and terrain,
both along and near the path, have a signicant bearing on the propagation of radio signals
and can cause both interference and signal cancellation.
When choosing a site, consider the effects of the following common obstacles:
• Trees and large plants - A tree directly in the signal path can completely block the
signal. You can avoid this by leaving sufcient clearance above the treetops.
You may need to leave extra clearance above smaller tress to allow for future
growth into the signal path.
• Man-made obstacles - A large round building such as a gas storage
reservoir or water tower that is partially in the path may cause some blocking.
These obstacles may also reect RF, which can lead to multi path interference
with other receivers. Objects in or near the path that have rectangular surfaces
can block and diffract signals over and around them.
• Earth surface - The earth’s curvature may also interfere with the signal if the
antenna is mounted too low. Mount the antenna just high enough to allow
adequate clearance from the ground.
Note:
For tower installations, you may need to climb the tower to verify a
clear signal path to the other antenna.
