Installation Requirements

• 13 mm wrench

• Shielded Category 5 (or above) cabling with drain wire

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

• Surge protection should be used for all outdoor installations.
We recommend that you use two Ethernet Surge Protectors,
model ETH-SP, one near the PowerBeam and the other at the
entry point to the building. The ETH-SP will absorb power
surges and safely discharge them into the ground.

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:

-73 dBm

-65 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

1. Align and insert the tabs of the Dish Bracket into the

slots of the Dish Reflector. Rotate the Dish Bracket

counter-clockwise until the tabs lock into place.
