Reset Button To reset to factory defaults, press and hold the

Reset button for more than 10 seconds while the device is
poweredon. Alternatively, the device may be reset remotely
via a Reset button located on the bottom of the Gigabit
PoE adapter.

Release Button After you assemble the device, 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:

-73 dBm

-65 dBm

-80 dBm -94 dBm

Application Examples

The PowerBeam mounted outdoors with the Reflector

installed provides directional outdoor coverage (gain is
reflector‑dependent).

The PowerBeam mounted outdoors without the 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 Mounting Bracket into
the slots of the Reflector. Rotate the Mounting Bracket
counterclockwise until the alignment holes in the dish and

bracket align with each other.

2. For added support in high‑wind environments, insert four

Screws with Washers into the holes in the Reflector and
Mounting Bracket, and secure each screw with a Washer
and a Nylon Insert Lock Nut.
