Reset Button To reset to factory defaults, press and hold the
Reset button for more than 10 seconds while the PowerBeam
is already poweredon. 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
Power The Power LED will light blue when the
device is connected to a power source.
Ethernet The Ethernet LED will light steady blue
when an active Ethernet connection is made and
flash when there is activity.
Signal In airOS®, you can modify the threshold
value for the wireless signal strength LEDs on the
Wireless tab under Signal LED Thresholds. Each LED
will light when the wireless signal strength is equal
to or greater than the LED’s threshold value. The
default threshold values for these LEDs are shown
below:
-65 dBm -73 dBm -80 dBm -94 dBm

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
harmful outdoor environments and destructive ESD events
with industrial‑grade, shielded Ethernet cable from Ubiquiti
Networks. For more details, visit www.ubnt.com/toughcable

Installation
1. Align and insert the tabs of the Adjustment Bracket into the
slots of the Dish Reflector. Rotate the Adjustment Bracket
counterclockwise until the alignment holes in the dish and
bracket align with each other.

2. Line up the Alignment Pins of the Rear Housing with the
alignment holes of the Adjustment Bracket. Push the Rear
Housing into the Adjustment Bracket.
Note: In high‑wind environments, you can add support
with additional hardware (not included):
1. Using the four holes in the Adjustment Bracket as a
template, drill four holes into the Dish Reflector with a
4.4 mm or 11/64" drill bit.
2. Secure the Dish Reflector to the Adjustment Bracket
using M4 screws, washers, and nuts (not included).

locked into place.
IMPORTANT: Before proceeding, lightly pull the Rear
Housing to confirm that it is locked into place.
4. Push in the sides of the Cable Door and detach it from the
Rear Housing.

5. Attach the Antenna Feed.
a. Insert the Antenna Feed into the Rear Housing, and push
