Lightning Protection Unit kit such as the HyperLink AL-CAT6HPJW Lightning Protector should be used. For more
information on Motorola Solution's PTP Lightning Protection Unit, refer to the PTP-LPU Technical Specifications.

2.6.3 Non Root Node Placement

The same guidelines as Root nodes apply to Non Root nodes with the exception of a backhaul requirement
The placement of Non Root nodes will depend heavily on the RF network design. Consider the guidelines for
optimizing wireless network performance when identifying potential mounting sites.
In addition, consider the following when planning for Non Root node placement:
• Light Poles, Utility Poles, or Traffic Poles
• Obtain all required supplemental agreements from local governments and utilities
• Obtain a generic mounting agreement that is not specify specific poles, since installation locations
may need to be modified during deployment
• Plan for AC power usage of 84 watts average, 126 watts peak
• The AP 7181 is rated for wind loading of up to160 miles per hour and 30 pounds per square foot.
• Ensure that proper grounding can be established
• The grounding cable for an AP 7181 must be a #8 gauge (10 mm) wire cross section and use a ring lug
that will fit the M5 grounding screw on the bottom of the unit
• Rooftops and Towers
• May require lease agreements
• Identify Access Point locations based on optimal communication with the Root nodes
• Non root node placement will be dependent on asset availability, terrain, etc.
• Ensure that nodes are placed at the same height
• Build the network outward from each root node, from least to greatest number of hops
As with Root node nodes, it should be noted it is incumbent upon the customer to obtain the required pole
attachment agreements for devices to be installed on traffic / utility poles. Obtaining the agreements can be a
lengthy process, so ample lead time must be allowed.
The potential pole locations should be logged with GPS to obtain accurate coordinates. Also log any identifying
numbers on the pole so this information can be provided to the appropriate utility agency. Alternate mounting
locations should also be identified in the event that your initial request is denied.
Specialized brackets may be required for attaching devices to decorative light poles and these brackets may have
to be custom fabricated. In this case, allow enough lead time for ordering the proper equipment.
Also consider any requirements to coordinate requests with multiple utility agencies within the same community.
Verify light pole selections have power available continuously and the power source is within the operational range
of the device being connected.
