Preparing for Installation

It is advisable to connect and check the PoE connection, Ethernet cables, and LEDs before installing the 
bridge in a hard-to-reach location. Additionally, observe the following items before mounting or 
connecting the bridge:

Grounding Point

In the event of electrostatic shock the connection of an insulated cable to the 
grounding point to an earthed point protects the unit from excessive electrical 
discharge. A grounding screw is provided in the package contents.

Integrated Antenna

Built in 5.0 GHz flat panel high-gain antenna.

WARNING:

 

 To comply with FCC radio frequency (RF) exposure limits, a minimum body-to-

antenna distance of 20 cm (8 in.) must be maintained when the bridge is operational.

WARNING:

  To avoid possible injury or damage to equipment, you must use power supply equipment 

that is safety certified according to UL, CSA, IEC, or other applicable national or international safety 
requirements for the country of use. All references to power supply in this document refer to equipment 
meeting these requirements.
