Reset Button  To reset to factory defaults, press and hold the 
Reset button for more than 10 seconds while the PowerBeam 
is already poweredon. Alternatively, the PowerBeam may be 
reset remotely via a Reset button located on the bottom of the 
Gigabit PoE Adapter.
Release Button  After you assemble the PowerBeam, check 
the Release button; it should be fully engaged in the Release 
Button Slot of the Rear Housing. This ensures that the Antenna 
Feed is locked into place. If you need to remove the Antenna 
Feed, you must depress the Release button first.
LEDs
Signal  The default values (from left to right) are 
shown below:
LED will light blue when the wireless signal 
strength is equal to or above -65 dBm.
LED will light blue when the wireless signal 
strength is equal to or above -73 dBm.
LED will light blue when the wireless signal 
strength is equal to or above -80 dBm.
LED will light blue when the wireless signal 
strength is equal to or above -94 dBm.
Ethernet  The Ethernet LED will light steady blue 
when an active Ethernet connection is made and 
flash when there is activity.
Power  The Power LED will light blue when the 
device is connected to a power source.
Application Examples
The PowerBeam mounted outdoors with the Dish Reflector 
installed provides directional outdoor coverage (gain is 
reflector‑dependent).
The PowerBeam mounted outdoors without the Dish Reflector 
installed provides outdoor‑to‑indoor coverage using the 3 dBi 
Antenna Feed only.
Installation Requirements
•  13 mm wrench
•  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
Installation
1.  Line up the Alignment Pins of the Rear Housing with the 
alignment holes of the Dish Reflector. Insert the pins and 
push until they lock intoplace.
2.  Push in the sides of the Cable Door and detach it from the 
Rear Housing.
3.  Attach the Antenna Feed:
a.  Insert the Antenna Feed into the Rear Housing, and push 
until it locks into place with a click. 
b.  Lightly pull the Antenna Feed to ensure that it is locked 
into place and the Release button is fully engaged.

4.  Connect the Ethernet cable:
a.  Connect an Ethernet cable to the Ethernet Port of the 
Antenna Feed. 
b.  Re-attach the Cable Door to the Rear Housing.
5.  Attach two Flanged Bolts, two Lock Washers, and two Flat 
Washers to the bottom of the Mounting Bracket. Ensure that 
there is a gap of 8 mm between each Flat Washer and the 
Mounting Bracket.
Note: Ensure that each Lock Washer is always 
installed between the Flanged Bolt and Flat Washer.

7.  Attach one Pole Clamp to the Upper Pole Bracket Assembly.
a.  Insert two Carriage Bolts into the Upper Pole Bracket 
Assembly. 
b.  Slide the closed slotted hole of the Pole Clamp over one 
CarriageBolt. 
c.  Place one Serrated Flange Nut on each Carriage Bolt.
8.  Attach one Pole Clamp to the Lower Pole Bracket.
a.  Insert two Carriage Bolts into the Lower Pole Bracket. 
b.  Slide the closed slotted hole of the Pole Clamp over one 
CarriageBolt.
c.  Place one Serrated Flange Nut on each Carriage Bolt.
9.  Attach the Lower Pole Bracket to a pole.
a.  Ensure that the slots face up.
b.  Slide the open hole of the Pole Clamp over the 
corresponding CarriageBolt.
c.  Tighten the Serrated Flange Nuts of the CarriageBolts to 
secure the Lower Pole Bracket to the pole.
Note: The mounting assembly can accommodate a 
Ø 38 - 101 mm pole.

10. Set the correct distance between the Pole Brackets.
IMPORTANT: Find the Foam Gauge supplied with the 
packaging; DO NOT DISCARD IT.
a.  Hold the Upper Pole Bracket Assembly against the pole.
b.  Fit the Foam Gauge over the Upper and Lower Pole 
Brackets to set the correct distance between them.

Assembly
11. Attach the Upper Pole Bracket Assembly to the pole:
a.  Slide the open hole of the Pole Clamp over the 
corresponding CarriageBolt.
b.  Ensure that the brackets are aligned parallel to each 
other, and then tighten the Serrated Flange Nuts of the 
CarriageBolts to 50 N-m.
Brackets are properly aligned. Top view: Brackets are mis-aligned.
12. Remove the Foam Gauge.
13. Lift the Dish Reflector and align the two lower Flanged Bolts 
with the slots on the Lower Pole Bracket. Seat the bolts in 
the slots.
14. Attach the vertical slot of the Adjustment Arm to the upper 
right Mounting Bracket using a Flanged Bolt, Lock Washer, 
and FlatWasher.
15. Before adjusting the tilt angle, ensure that the five Flanged 
Bolts are loose enough to allow movement.
IMPORTANT: If you cannot spin the washers freely 
by hand, then loosen the Flanged Bolts until you can.
16. To adjust the tilt angle, turn the screw head of the elevation 
rod until the desired tilt is reached.
Note: If the PowerBeam is difficult to tilt up or down, 
use the Foam Gauge to check the spacing and 
ensure that the Flanged Bolts are loose enough.
17. Rotate the Support Arm down and attach its horizontal slot 
to the Upper Pole Bracket Assembly using a Flanged Bolt, 
Lock Washer, and FlatWasher.
Note: Ensure that the degree settings are the same 
on the Support Arm and Adjustment Arm.
