Installation and Initialization
Tsunami MP-8100 Installation and Management Guide 24
NOTE: Write down the ports to which you have connected the antenna. This will be useful during the configuration of
MIMO parameters.
Units with integrated antennas must always be mounted in Square position to achieve Horizontal and Vertical polarization.
Step 10: Install Surge Protector
Proxim recommends two approved lightning surge protectors to be installed, one near to the device (supplied with the
product package) and the other near to the building ingress point.
Perform the following steps to ensure proper surge protection:
1. Mount the provided surge protector near the outdoor equipment and use 10 AWG or better wire to connect the
protector’s ground lug to the appropriate mounting ground point. The outdoor equipment and co-located surge
protector should have a common grounding point using the shortest possible grounding cable.
2. Mount a second surge protector near the building ingress and use 10 AWG or better wire to connect the protector’s
ground lug to earth ground as shown in the following figure.
NOTE: Use Outdoor-rated, UV protected, shielded Cat5e/Cat6 cable for the following.
3. Connect an RJ45 terminated cable between the indoor equipment and to the port on the surge protector at the
building ingress.
4. Connect a short RJ45 terminated cable between the outdoor equipment and the port on the co-located surge
protector.
5. Connect an RJ45 terminated cable between the two surge protectors on their remaining ports.
Step 11: Ground the Unit
To ensure proper grounding, use either of the ground points which are situated at the bottom corners of the unit and the
grounding screw provided to attach a ground wire of at least 10 AWG stranded to the unit. It is important to note that the
following ground guidelines are followed during installations:
1. Cut any extra ground wire length when finished connecting it to the single point earth ground.
2. Avoid sharp bends and never loop or coil up the ground wire, always connect it straight to ground.
3. A good earth ground impedance is less than 1.0 ohm.
4. Measure ground impedance at the point where the protector ground wire is connected and not at the ground rod.
5. Connect the protector ground wire and equipment ground (both power ground and telecomm ground) to a single
common ground.
6. Make sure all connections are fastened securely and are tight.
7. Never install during a storm and always follow your local safety codes.
8. Connect the grounding wire, which is supplied with the product package, to the grounding lug as shown below:
