Ethernet Port The Ethernet port is a 10/100 Mbps port used
for data and supplies power to the PowerBridgeM. Power can
be provided by any of the following:
• PoE adapter (included)
• Ubiquiti Networks TOUGHSwitch™PoE
• Ubiquiti Networks EdgeRouter™PoE
Reset Button To reset to factory defaults, press and hold
the Reset button for more than 10 seconds while the
PowerBridgeM is already poweredon.

LEDs
Power The Power LED will light green when the
device is connected to a power source.
Ethernet The Ethernet LED will light steady green
when an active Ethernet connection is made and
flash when there is activity.
Signal In airOS, you can modify the wireless signal
strength threshold values for each LED on the
Advanced tab under Signal LED Thresholds. The
default values are shown below:
LED will light red when the wireless signal
strength is above -94 dBm.
LED will light amber when the wireless signal
strength is above -80 dBm.
LED will light green when the wireless signal
strength is above -73 dBm.
LED will light green when the wireless signal
strength is above -65 dBm.

Installation Requirements
• 13 mm or ½" wrench
• Flathead screwdriver
• Shielded Category 5 (or above) cabling should be used for
all wired Ethernet connections and should be grounded
through the AC ground of the PoE.
We recommend that you protect your networks from the
most brutal environments and devastating ESD attacks
with industrial-grade shielded Ethernet cable from Ubiquiti
Networks. For more details, visit www.ubnt.com/toughcable
Hardware Installation
To install the PowerBridgeM, perform the following steps:
1. The Port Cover is hinged to the PowerBridgeM and locked
with a screw. Use a flathead screwdriver to turn the locking
screw counter-clockwise until it is loose. Open the cover by
sliding it down and raising it up.

2. Connect an Ethernet cable to the Ethernet Port.
3. Close the Port Cover and lock it in place by turning the
locking screw clockwise.
4. Insert two Carriage Bolts into each Pole Bracket.

5. Connect the Pole Brackets to the U-Brackets using the four
Flange Bolts.

6. Mount the PowerBridgeM to the pole:
a. Position the Carriage Bolts around the pole at the
mounting location.
b. Slide a Pole Clamp onto each pair of Carriage Bolts.
c. Hand-tighten a Flange Nut on each Carriage Bolt.
Note: The mounting assembly can accommodate a
Ø 1.25" - 2.2" pole.
7. Rotate the PowerBridgeM to the correct azimuth towards
the other end of the wireless link.

8. Adjust the elevation angle as needed:
a. Loosen the four Flange Bolts on the U-Brackets.
b. Adjust the PowerBridgeM to the desired elevation tilt.
c. Tighten all bolts and nuts to approximately
25 N-m (18 lb-ft).

Powering the PowerBridgeM
The PowerBridgeM can be powered by the included PoE
Adapter or any of the following compatible PoE switches:
• TOUGHSwitch PoE, model TS-5-POE
• TOUGHSwitch PoE PRO, model TS-8-PRO
• EdgeRouter PoE, model ERPoe-5
Connecting to the PoE Adapter
1. Connect the other end of the Ethernet cable from the
PowerBridgeM to the Ethernet port labeled POE on the
PoEAdapter.
2. Connect an Ethernet cable from your LAN or computer to
the Ethernet port labeled LAN on the PoE Adapter.
