7320: 2.4 & 5.4 GHz, DC Power, NoBatt, ETSI Preparing for Installation The Tropos 7320 router must be installed by a trained professional, value added reseller, or systems integrator who is familiar with RF planning issues and regulatory limits defined by the governing body of the country in which the unit will be installed.
Wood pole mounting only: two 1/4-inch diameter, 3 1/2-inch long lag bolts Site Planning To ensure safe and durable wiring, installation of the Tropos 7320 router must follow appropriate electrical and building codes. Follow the National Electrical Code (NEC) requirements, unless local codes in your area take precedence over the NEC code.
Chapter 1 Location Guidelines The Tropos 7320 router is a radio devices and therefore susceptible to interference that can reduce throughput and range. Follow these guidelines to ensure the best performance: Install the unit in an area where trees, buildings, and large steel structures do not obstruct radio signals to and from the antenna.
Make sure that grounding is complete before you connect power to the router. Safety Installing the Tropos 7320 router can pose a serious hazard. Be sure to take precautions to avoid the following: Exposure to high voltage lines during installation...

Chapter 1 Proper Use of Hose Clamps The mounting assembly for the Tropos 7320 router contains hose clamps to secure the router to the mounting structure. Figure 3 illustrates the proper use of the hose clamps. The clamps must be routed through slots in the pole bracket as shown in the figure, and then attached to the pole and tightened.
Chapter 1 Pole, Tower, and Streetlight Mounting Instructions This section explains how to mount the Tropos 7320 router on a pole, tower, or streetlight. It is best to mount the router to aluminum or galvanized steel structures. The mounting brackets are designed to pierce any oxidation layers that are on the outside of the pole, thereby assuring good quality connection to the grounded structure.
Figure 4 illustrates the proper method of mounting the router on an outdoor metal pole. Note Antennas must be clear of obstruction. Metal Pole Mounting FIGURE 4 Pole bracket (rotated) Sun shield trp_097 Router trp_153 trp_198 Tropos 7320 Router Installation Guide...
