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
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 blue when the wireless signal
strength is above -65 dBm.
LED will light blue when the wireless signal
strength is above -73 dBm.
LED will light blue when the wireless signal
strength is above -80 dBm.
LED will light blue when the wireless signal
strength is 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 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 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. Align and insert the tabs of the Mounting Bracket into
the slots of the Reflector. Rotate the Mounting Bracket
counter-clockwise 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.
