Mounting Bracket
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. For more details, visit ui.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.

This Gigabit Ethernet port is used to connect the power and should be connected
to the LAN and DHCP server.
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.
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.

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:
The Ethernet LED will light steady blue when an active Ethernet connection is
made and flash when there is activity.
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).

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).
